Subject: [PATCH 001/855] [SCSI] blacklist REPORT LUNS usage on transtec arrays
They report being SCSI-3 but seem to give back rubbish to a
REPORT_LUNS command. Force them to be sequentially scanned.

Subject: [PATCH 002/855] [SCSI] ibmvscsi compatibility fix
Linda Xie ever so gently pointed out that she had a patch
to preserve compatibility with older SLES targets, and I told
her we didn't need to push it to mainline.
This patch explicitly checks the version of the IBMVSCSI target
and ensures that large scatterlists are not sent to older
targets.

Subject: [PATCH 003/855] [SCSI] aic7xxx: move to dma_get_required_mask() and
correct 39 bit assumptions
This patch moves aic7xxx over to the dma_get_required_mask() API and
dumps its open coded memory check.
It also appears from this bug:
https://bugzilla.redhat.com/bugzilla/show_bug.cgi?id=167049
That 39 bit addressing doesn't work on older cards. I surmise that the
AHC_LARGE_SCBS flag is the one that marks cards capable of using 39 bit
addressing, so I also folded that check into the code.

Subject: [PATCH 004/855] [PATCH] s390: TSO related fixes in qeth driver
Jeff,
I'm sorry seems that they have not been sent out either ...
ok here they come ...
[patch 3/4] s390: TSO related fixes in qeth driver
From: Frank Pavlic <pavlic@de.ibm.com>
TSO related fixes :
- changing value of large_send attribute while network traffic
is running caused program check and thus device recovery.
- Due to hardware restriction discard packet when it exceeds 60K
otherwise qeth will cause program checks and thus traffic stall
when trying to send such huge packets.

OK, my fault. Your fix is almost correct .. I was going to do this
eventually, honest, because there's no need to unprep and reprep a
command that comes in through scsi_queue_insert().
However, I decided to leave it in to exercise the scsi_unprep_request()
path just to make sure it was working. What's happening, I think, is
that we also use this path for retries. Since we kill and reget the
command each time, the retries decrement is never seen, so we're
retrying forever.

Subject: [PATCH 009/855] [TCP]: Compute in_sacked properly when we split up a
TSO frame.
The problem is that the SACK fragmenting code may incorrectly call
tcp_fragment() with a length larger than the skb->len. This happens
when the skb on the transmit queue completely falls to the LHS of the
SACK.
And add a BUG() check to tcp_fragment() so we can spot this kind of
error more quickly in the future.

Subject: [PATCH 014/855] [IPVS]: ip_vs_ftp breaks connections using
persistence
ip_vs_ftp when loaded can create NAT connections with unknown client
port for passive FTP. For such expectations we lookup with cport=0 on
incoming packet but it matches the format of the persistence templates
causing packets to other persistent virtual servers to be forwarded to
real server without creating connection. Later the reply packets are
treated as foreign and not SNAT-ed.
This patch changes the connection lookup for packets from clients:
* introduce IP_VS_CONN_F_TEMPLATE connection flag to mark the
connection as template
* create new connection lookup function just for templates -
ip_vs_ct_in_get
* make sure ip_vs_conn_in_get hits only connections with
IP_VS_CONN_F_NO_CPORT flag set when s_port is 0. By this way
we avoid returning template when looking for cport=0 (ftp)

Subject: [PATCH 015/855] [IPV6]: Fix per-socket multicast filtering in
sk_reuse case
per-socket multicast filters were not being applied to all sockets
in the case of an exact-match bound address, due to an over-exuberant
"return" in the look-up code. Fix below. IPv4 does not have this problem.
Thanks to Hoerdt Mickael for reporting the bug.

Subject: [PATCH 017/855] [LIB]: Consolidate _atomic_dec_and_lock()
Several implementations were essentialy a common piece of C code using
the cmpxchg() macro. Put the implementation in one spot that everyone
can share, and convert sparc64 over to using this.
Alpha is the lone arch-specific implementation, which codes up a
special fast path for the common case in order to avoid GP reloading
which a pure C version would require.

From 917afce1000d978dfd3f07da5da9d864bc49c77e Mon Sep 17 00:00:00 2001
From: Lennert Buytenhek <buytenh@wantstofly.org>

Subject: [PATCH 019/855] [ARM] 2911/1: ixp2000_reg_{read,write} accessors
Patch from Lennert Buytenhek
This patch:
- changes the ixp2000_reg_write accessor to take a 'volatile void *'
instead of a 'volatile unsigned long *', which then allows passing in
a u32 * as first argument without being greeted with a warning; and
- adds an ixp2000_reg_read accessor.
We can then use these accessors in ixp2000 code to access on-chip
peripherals, instead of directly dereferencing pointers. This is for
use by the ixp2000 microengine driver which was recently announced on
netdev. We can't use readl/writel on the ixp2000 since it is usually
run in big-endian mode, and on big-endian platforms, readl/writel
perform byteswapping.
A future patch will remove the readback from ixp2000_reg_write, since
it's not needed to prevent erratum #66, and add manual readbacks to the
places that need them (writes are not synchronous since we map in device
space using XCB=101 nowadays), such as interrupt disabling and GPIO
manipulation. See also:
http://lists.arm.linux.org.uk/pipermail/linux-arm-kernel/2005-February/027084.html
Patch has been ACKed by Jeff Garzik.

Subject: [PATCH 020/855] [ARM] 2909/1: remove IXP2000_PROD_ID
Patch from Lennert Buytenhek
The intel docs call it IXP2000_PRODUCT_ID, and we have a definition
for IXP2000_PRODUCT_ID as well, so IXP2000_PROD_ID can go. It's only
used in one place.

Subject: [PATCH 022/855] [ARM] 2905/1: enable the ixp2000 i2c bus driver in
ixp2000 defconfigs
Patch from Lennert Buytenhek
It's silly to have I2C enabled in all ixp2000 defconfigs but not to
have the ixp2000 bus driver enabled in any of them. This patch enables
CONFIG_I2C_IXP2000 for all in-tree ixp2000 boards.

Subject: [PATCH 027/855] [SCSI] atp870u: fix memory addressing bug
From: Alan Cox <alan@redhat.com>
The virt_to_bus() wasn't correctly taken out of this driver. It needs
to be able to track both physical and virtual addresses for its prd table.
Update the driver to do this with separate tracking entries.

Subject: [PATCH 028/855] [ARM] Tighten pfn_valid() test.
Thomas Gleixner reported that mmaping and unmapping each physical
page in turn eventually caused the kernel to oops. It appears
that pfn_valid() in the discontigmem case was too simplistic for
proper operation.
Tighten the logic so we also check if the PFN is within the range
of the selected memory node.

Subject: [PATCH 029/855] [PATCH] ppc64: Fix recent regression
As noted by Olof Johansson <olof@lixom.net>:
"A recent patch changed the way the LPAR bit is checked during early
boot. This resulted in a polarity change in a conditional branch
without changing the branch, causing at least some legacy machines to
not boot."
This fixes it.

Subject: [PATCH 031/855] [PATCH] vgacon: Fix sanity checking in vgacon_resize
Reported by: walt <wa1ter@myrealbox.com>
"I routinely switch the console font during bootup to
8x8 so I can get 50 lines per screen. Until 09 Sept,
just changing to the small font automatically gave me
all 50 lines -- but now I'm only getting 25 lines even
with the small font. The bottom half of the screen
displays the text that already scrolled off the top."
This bug is due to an erroneous check in the recently added hook,
vgacon_resize(). It checks the new height against the original number of
rows of the console. Because the original number of rows depends on both
the scanline and the font height, check it instead against the
scanline/fontheight.

Subject: [PATCH 037/855] [PATCH] bonding: plug reference count leak
Bonding leaks route structures when the ARP monitor is
configured to send probes over VLANs.
Originally reported by Ian Abel <ian.abel@mxtelecom.com>; his
original fix was modified by Jay Vosburgh to correct coding style and to
close a leak it missed.

Subject: [PATCH 040/855] [libata] fix PIO completion race
Make sure we that completion is the final action we take; prior to this
change, another CPU may have changed ap->pio_task_state before we tested
it a final time.
Spotted by, and original patch by Albert Lee @ IBM.
Also includes a minor optimization: eliminate a ton of unnecessary
queue_work() calls, simply by jumping to the beginning of the FSM
function ata_pio_task().

Subject: [PATCH 041/855] [SCSI] change port speed definitions for
scsi_transport_fc
obviously FC Port Speeds in scsi_transport_fc.h are defined according
to FC-HBA:
#define FC_PORTSPEED_1GBIT 1
#define FC_PORTSPEED_2GBIT 2
#define FC_PORTSPEED_10GBIT 4
#define FC_PORTSPEED_4GBIT 8
Problem is, whoever invented FC-HBA did not care about FC-FS or
FC-GS-x. Following FC-FS/FC-GS-x defintions of port speeds would look
like:
1 GBit: 0x0001
2 GBit: 0x0002
4 GBit: 0x0004
10GBit: 0x0008
(and new in FC-LS:
8 Gbit: 0x0010
16GBit: 0x0020)
I really appreciate if scsi_transport_fc.h would define port speeds
according to FC-GS-x/FC-FS. Thus mapping of port speed capabilities to
values defined in scsi_transport_fc.h can be avoided in the LLDD.
Attached is a patch to change the definitions.

+An ad-hoc collection of notes on IA64 MCA and INIT processing. Feel
+free to update it with notes about any area that is not clear.
+
+---
+
+MCA/INIT are completely asynchronous. They can occur at any time, when
+the OS is in any state. Including when one of the cpus is already
+holding a spinlock. Trying to get any lock from MCA/INIT state is
+asking for deadlock. Also the state of structures that are protected
+by locks is indeterminate, including linked lists.
+
+---
+
+The complicated ia64 MCA process. All of this is mandated by Intel's
+specification for ia64 SAL, error recovery and and unwind, it is not as
+if we have a choice here.
+
+* MCA occurs on one cpu, usually due to a double bit memory error.
+ This is the monarch cpu.
+
+* SAL sends an MCA rendezvous interrupt (which is a normal interrupt)
+ to all the other cpus, the slaves.
+
+* Slave cpus that receive the MCA interrupt call down into SAL, they
+ end up spinning disabled while the MCA is being serviced.
+
+* If any slave cpu was already spinning disabled when the MCA occurred
+ then it cannot service the MCA interrupt. SAL waits ~20 seconds then
+ sends an unmaskable INIT event to the slave cpus that have not
+ already rendezvoused.
+
+* Because MCA/INIT can be delivered at any time, including when the cpu
+ is down in PAL in physical mode, the registers at the time of the
+ event are _completely_ undefined. In particular the MCA/INIT
+ handlers cannot rely on the thread pointer, PAL physical mode can
+ (and does) modify TP. It is allowed to do that as long as it resets
+ TP on return. However MCA/INIT events expose us to these PAL
+ internal TP changes. Hence curr_task().
+
+* If an MCA/INIT event occurs while the kernel was running (not user
+ space) and the kernel has called PAL then the MCA/INIT handler cannot
+ assume that the kernel stack is in a fit state to be used. Mainly
+ because PAL may or may not maintain the stack pointer internally.
+ Because the MCA/INIT handlers cannot trust the kernel stack, they
+ have to use their own, per-cpu stacks. The MCA/INIT stacks are
+ preformatted with just enough task state to let the relevant handlers
+ do their job.
+
+* Unlike most other architectures, the ia64 struct task is embedded in
+ the kernel stack[1]. So switching to a new kernel stack means that
+ we switch to a new task as well. Because various bits of the kernel
+ assume that current points into the struct task, switching to a new
+ stack also means a new value for current.
+
+* Once all slaves have rendezvoused and are spinning disabled, the
+ monarch is entered. The monarch now tries to diagnose the problem
+ and decide if it can recover or not.
+
+* Part of the monarch's job is to look at the state of all the other
+ tasks. The only way to do that on ia64 is to call the unwinder,
+ as mandated by Intel.
+
+* The starting point for the unwind depends on whether a task is
+ running or not. That is, whether it is on a cpu or is blocked. The
+ monarch has to determine whether or not a task is on a cpu before it
+ knows how to start unwinding it. The tasks that received an MCA or
+ INIT event are no longer running, they have been converted to blocked
+ tasks. But (and its a big but), the cpus that received the MCA
+ rendezvous interrupt are still running on their normal kernel stacks!
+
+* To distinguish between these two cases, the monarch must know which
+ tasks are on a cpu and which are not. Hence each slave cpu that
+ switches to an MCA/INIT stack, registers its new stack using
+ set_curr_task(), so the monarch can tell that the _original_ task is
+ no longer running on that cpu. That gives us a decent chance of
+ getting a valid backtrace of the _original_ task.
+
+* MCA/INIT can be nested, to a depth of 2 on any cpu. In the case of a
+ nested error, we want diagnostics on the MCA/INIT handler that
+ failed, not on the task that was originally running. Again this
+ requires set_curr_task() so the MCA/INIT handlers can register their
+ own stack as running on that cpu. Then a recursive error gets a
+ trace of the failing handler's "task".
+
+[1] My (Keith Owens) original design called for ia64 to separate its
+ struct task and the kernel stacks. Then the MCA/INIT data would be
+ chained stacks like i386 interrupt stacks. But that required
+ radical surgery on the rest of ia64, plus extra hard wired TLB
+ entries with its associated performance degradation. David
+ Mosberger vetoed that approach. Which meant that separate kernel
+ stacks meant separate "tasks" for the MCA/INIT handlers.
+
+---
+
+INIT is less complicated than MCA. Pressing the nmi button or using
+the equivalent command on the management console sends INIT to all
+cpus. SAL picks one one of the cpus as the monarch and the rest are
+slaves. All the OS INIT handlers are entered at approximately the same
+time. The OS monarch prints the state of all tasks and returns, after
+which the slaves return and the system resumes.
+
+At least that is what is supposed to happen. Alas there are broken
+versions of SAL out there. Some drive all the cpus as monarchs. Some
+drive them all as slaves. Some drive one cpu as monarch, wait for that
+cpu to return from the OS then drive the rest as slaves. Some versions
+of SAL cannot even cope with returning from the OS, they spin inside
+SAL on resume. The OS INIT code has workarounds for some of these
+broken SAL symptoms, but some simply cannot be fixed from the OS side.
+
+---
+
+The scheduler hooks used by ia64 (curr_task, set_curr_task) are layer
+violations. Unfortunately MCA/INIT start off as massive layer
+violations (can occur at _any_ time) and they build from there.
+
+At least ia64 makes an attempt at recovering from hardware errors, but
+it is a difficult problem because of the asynchronous nature of these
+errors. When processing an unmaskable interrupt we sometimes need
+special code to cope with our inability to take any locks.
+
+---
+
+How is ia64 MCA/INIT different from x86 NMI?
+
+* x86 NMI typically gets delivered to one cpu. MCA/INIT gets sent to
+ all cpus.
+
+* x86 NMI cannot be nested. MCA/INIT can be nested, to a depth of 2
+ per cpu.
+
+* x86 has a separate struct task which points to one of multiple kernel
+ stacks. ia64 has the struct task embedded in the single kernel
+ stack, so switching stack means switching task.
+
+* x86 does not call the BIOS so the NMI handler does not have to worry
+ about any registers having changed. MCA/INIT can occur while the cpu
+ is in PAL in physical mode, with undefined registers and an undefined
+ kernel stack.
+
+* i386 backtrace is not very sensitive to whether a process is running
+ or not. ia64 unwind is very, very sensitive to whether a process is
+ running or not.
+
+---
+
+What happens when MCA/INIT is delivered what a cpu is running user
+space code?
+
+The user mode registers are stored in the RSE area of the MCA/INIT on
+entry to the OS and are restored from there on return to SAL, so user
+mode registers are preserved across a recoverable MCA/INIT. Since the
+OS has no idea what unwind data is available for the user space stack,
+MCA/INIT never tries to backtrace user space. Which means that the OS
+does not bother making the user space process look like a blocked task,
+i.e. the OS does not copy pt_regs and switch_stack to the user space
+stack. Also the OS has no idea how big the user space RSE and memory
+stacks are, which makes it too risky to copy the saved state to a user
+mode stack.
+
+---
+
+How do we get a backtrace on the tasks that were running when MCA/INIT
+was delivered?
+
+mca.c:::ia64_mca_modify_original_stack(). That identifies and
+verifies the original kernel stack, copies the dirty registers from
+the MCA/INIT stack's RSE to the original stack's RSE, copies the
+skeleton struct pt_regs and switch_stack to the original stack, fills
+in the skeleton structures from the PAL minstate area and updates the
+original stack's thread.ksp. That makes the original stack look
+exactly like any other blocked task, i.e. it now appears to be
+sleeping. To get a backtrace, just start with thread.ksp for the
+original task and unwind like any other sleeping task.
+
+---
+
+How do we identify the tasks that were running when MCA/INIT was
+delivered?
+
+If the previous task has been verified and converted to a blocked
+state, then sos->prev_task on the MCA/INIT stack is updated to point to
+the previous task. You can look at that field in dumps or debuggers.
+To help distinguish between the handler and the original tasks,
+handlers have _TIF_MCA_INIT set in thread_info.flags.
+
+The sos data is always in the MCA/INIT handler stack, at offset
+MCA_SOS_OFFSET. You can get that value from mca_asm.h or calculate it
+as KERNEL_STACK_SIZE - sizeof(struct pt_regs) - sizeof(struct
+ia64_sal_os_state), with 16 byte alignment for all structures.
+
+Also the comm field of the MCA/INIT task is modified to include the pid
+of the original task, for humans to use. For example, a comm field of
+'MCA 12159' means that pid 12159 was running when the MCA was
+delivered.

Subject: [PATCH 050/855] [DCCP]: Introduce DCCP_SOCKOPT_SERVICE
As discussed in the dccp@vger mailing list:
Now applications have to use setsockopt(DCCP_SOCKOPT_SERVICE, service[s]),
prior to calling listen() and connect().
An array of unsigned ints can be passed meaning that the listening sock accepts
connection requests for several services.
With this we can ditch struct sockaddr_dccp and use only sockaddr_in (and
sockaddr_in6 in the future).

Subject: [PATCH 052/855] [NETFILTER] CLUSTERIP: introduce reference counting
for entries
The CLUSTERIP target creates a procfs entry for all different cluster
IPs. Although more than one rules can refer to a single cluster IP (and
thus a single config structure), removal of the procfs entry is done
unconditionally in destroy(). In more complicated situations involving
deferred dereferencing of the config structure by procfs and creating a
new rule with the same cluster IP it's also possible that no entry will
be created for the new rule.
This patch fixes the problem by counting the number of entries
referencing a given config structure and moving the config list
manipulation and procfs entry deletion parts to the
clusterip_config_entry_put() function.

Subject: [PATCH 053/855] [NETFILTER] CLUSTERIP: use a bitmap to store node
responsibility data
Instead of maintaining an array containing a list of nodes this instance
is responsible for let's use a simple bitmap. This provides the
following features:
* clusterip_responsible() and the add_node()/delete_node() operations
become very simple and don't need locking
* the config structure is much smaller
In spite of the completely different internal data representation the
user-space interface remains almost unchanged; the only difference is
that the proc file does not list nodes in the order they were added.
(The target info structure remains the same.)

Subject: [PATCH 054/855] [NETFILTER]: Fix oops in conntrack event cache
ip_ct_refresh_acct() can be called without a valid "skb" pointer.
This used to work, since ct_add_counters() deals with that fact.
However, the recently-added event cache doesn't handle this at all.
This patch is a quick fix that is supposed to be replaced soon by a cleaner
solution during the pending redesign of the event cache.

From c58ec93245a1fb7354f9e331960380827b9f41db Mon Sep 17 00:00:00 2001
From: Michael Chan <mchan@broadcom.com>

Subject: [PATCH 059/855] [TG3]: Fix 4GB boundary tx handling
Fix and simplify the workaround code for the 4GB boundary tx buffer
hardware bug.
1. Need to unmap the original SKB's dma addresses if a new SKB cannot
be allocated.
2. Need to pass the base flag to tigon3_4gb_hwbug_workaround() or TSO
won't work properly.
3. The guilty entry and length parameters for
tigon3_4gb_hwbug_workaround() are removed as they are not necessary.
4. Remove assumption that only one fragment can hit the 4GB boundary.
Another fragment can hit 8GB for example.

Got confused with the crypto update. The last patch added a call to
destroy_workqueue() for a non-existent workqueue with the comment "Remove
device workqueue on module unload". This is nonsense. Remove the offending
hunk again.

When an asynchronous interruption occurs during the execution of the
'critical section' within the generic interruption handling code (entry.S),
a faulty check for a userspace PSW may result in a corrupted kernel stack
pointer which subsequently triggers a stack overflow check.

Subject: [PATCH 072/855] [PATCH] uml: breakpoint an arbitrary thread
This patch implements a stack trace for a thread, not unlike sysrq-t does.
The advantage to this is that a break point can be placed on showreqs, so that
upon showing the stack, you jump immediately into the debugger. While sysrq-t
does the same thing, sysrq-t shows *all* threads stacks. It also doesn't work
right now. In the future, I thought it might be acceptable to make this show
all pids stacks, but perhaps leaving well enough alone and just using sysrq-t
would be okay. For now, upon receiving the stack command, UML switches
context to that thread, dumps its registers, and then switches context back to
the original thread. Since UML compacts all threads into one of 4 host
threads, this sort of mechanism could be expanded in the future to include
other debugging helpers that sysrq does not cover.
Note by jdike - The main benefit to this is that it brings an arbitrary thread
back into context, where it can be examined by gdb. The fact that it dumps it
stack is secondary. This provides the capability to examine a sleeping
thread, which has existed in tt mode, but not in skas mode until now.
Also, the other threads, that sysrq doesn't cover, can be gdb-ed directly
anyway.

Subject: [PATCH 076/855] [PATCH] uml: preserve errno in error paths
The poster child for this patch is the third tuntap_user hunk. When an ioctl
fails, it properly closes the opened file descriptor and returns. However,
the close resets errno to 0, and the 'return errno' that follows returns 0
rather than the value that ioctl set. This caused the caller to believe that
the device open succeeded and had opened file descriptor 0, which caused no
end of interesting behavior.
The rest of this patch is a pass through the UML sources looking for places
where errno could be reset before being passed back out. A common culprit is
printk, which could call write, being called before errno is returned.
In some cases, where the code ends up being much smaller, I just deleted the
printk.
There was another case where a caller of run_helper looked at errno after a
failure, rather than the return value of run_helper, which was the errno value
that it wanted.

From: Jeff Dike <jdike@addtoit.com>
Date: Fri, 16 Sep 2005 19:27:50 -0700
Subject: [PATCH 077/855] [PATCH] uml: move libc code out of mem_user.c and
tempfile.c
The serial UML OS-abstraction layer patch (um/kernel dir).
This moves all system calls from mem_user.c and tempfile.c files under
os-Linux dir.

PowerQUICC I devices
Added ppc_sys device and system definitions for PowerQUICC I devices. This
will allow drivers for PQI to be proper platform device drivers. Currently
sys section contains only MPC885 and MPC866. Identification should be done
with identify_ppc_sys_by_name call, with board-specific "name" string
passed, since PQI do not have any register that could identify the SOC.

Subject: [PATCH 091/855] [PATCH] PR_GET_DUMPABLE returns incorrect info
2.6.13 incorporated Alan Cox's patch for /proc/sys/fs/suid_dumpable (one
version of this patch can be found here
http://marc.theaimsgroup.com/?l=linux-kernel&m=109647550421014&w=2 ).
This patch also made corresponding changes in kernel/sys.c to change the
prctl() PR_SET_DUMPABLE operation so that the permitted range of 'arg2' was
modified from 0..1 to 0..2.
However, a corresponding change was not made for PR_GET_DUMPABLE: if the
dumpable flag is non-zero, then PR_GET_DUMPABLE always returns 1, so that
the caller can't determine the true setting of this flag.

Subject: [PATCH 093/855] [PATCH] dell_rbu: enhancements and fixes
BUG fixes:
The driver used to allocate memory with spinlock held which has been
fixed in this patch.
The driver was printing the entire buffer when it received a invalid
entry in image_type. The fix is to only print a warning message and not
the buffer.
Usability enhancements:
It is possible that due to user error the /sys/class/firmware/dell_rbu
entries might be missing, this can happen if the user does the following
echo 1 > /sys/class/firmware/dell_rbu/loading
echo 0 > /sys/class/firmware/dell_rbu/loading
This will make the entries in /sys/class/firmware/ to disappear and the
only way get them back was bby unloading and loading the driver.
This patch makes the user recreate these entries by echoing init in to
image_type.
This patch has been tested with Libsmbios and Dell OpenManage.

Subject: [PATCH 095/855] [PATCH] epoll: fix delayed initialization bug
Al found a potential problem in epoll_create(), where the
file->private_data member was set after fd_install(). This is obviously
wrong since another thread might do a close() on that fd# before we set the
file->private_data member. This goes over 2.6.13 and passes a few basic
tests I've done here.
(akpm: snuck in a kzalloc() cleanup too)

Subject: [PATCH 097/855] [PATCH] i2c: kill an unused i2c_adapter struct member
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit
Kill an unused member of the i2c_adapter structure. This additionally
fixes a potential bug, because <linux/i2c.h> doesn't include
<linux/config.h>, so different files including <linux/i2c.h> could see a
different definition of the i2c_adapter structure, depending on them
including <linux/config.h> (or other header files themselves including
<linux/config.h>) before <linux/i2c.h>, or not.
Credits go to Jörn Engel for pointing me to the problem.

Subject: [PATCH 098/855] [PATCH] Add smp_mb__after_clear_bit() to
unlock_kiocb()
Add smp_mb__after_clear_bit() to unlock_kiocb()
AIO's use of wait_on_bit_lock()/wake_up_bit() forgot to add a barrier
between clearing its lock bit and calling wake_up_bit() so wake_up_bit()'s
unlocked waitqueue_active() can race. This puts AIO's use in line with the
others and the comment above wake_up_bit().

+ Chapter 13: Allocating memory
+
+The kernel provides the following general purpose memory allocators:
+kmalloc(), kzalloc(), kcalloc(), and vmalloc(). Please refer to the API
+documentation for further information about them.
+
+The preferred form for passing a size of a struct is the following:
+
+ p = kmalloc(sizeof(*p), ...);
+
+The alternative form where struct name is spelled out hurts readability and
+introduces an opportunity for a bug when the pointer variable type is changed
+but the corresponding sizeof that is passed to a memory allocator is not.
+
+Casting the return value which is a void pointer is redundant. The conversion
+from void pointer to any other pointer type is guaranteed by the C programming
+language.

Subject: [PATCH 101/855] [PATCH] files: fix preemption issues
With the new fdtable locking rules, you have to protect fdtable with either
->file_lock or rcu_read_lock/unlock(). There are some places where we
aren't doing either. This patch fixes those places.

ioctl
When doing ioctl HDIO_DRIVE_TASKFILE, the ide_task_t's request pointer is
never set, but flagged_taskfile and do_rw_taskfile pass it as a parameter
to the prehandler. The kernel will oops taskfile pio-out commands because
of this (taskfile pio-in doesn't use a prehandler). This fix sets the
request pointer at the time the request is created to stop this oops.

Subject: [PATCH 109/855] [SCSI] fix oops in scsi_release_buffers()
I found one other thing that needs to be fixed. The call to
scsi_release_buffers in scsi_unprep_request causes an oops, because the
sgtable has already been freed in scsi_io_completion. The following patch
is needed.

They seem to have been due to AMD errata 63/122; the fix is to disable
TLB flush filtering in SMP configurations.
Confirmed to fix the problem by Andrew Walrond <andrew@walrond.org>
[ Let's see if we'll have a better fix eventually, this is the Q&D
"let's get this fixed and out there" version ]

bond_init() is not releasing rtnl_sem after register_netdevice() and before
calling unregister_netdevice() (from bond_free_all()) in the exception
path. As the device registration is not completed (dev->reg_state ==
NETREG_REGISTERING), the call to unregister_netdevice() triggers
BUG_ON(dev->reg_state != NETREG_REGISTERED).

(Re: xfrm_lookup)
I think we should cache the per-socket route(dst_entry) only when the
IPv6 UDP socket is connect(2)'ed.
(which is same as IPv4 UDP send behavior)

Subject: [PATCH 120/855] [ARM] 2917/1: Make IXP4xx mach_desc's depend on
config options
Patch from Deepak Saxena
Building a kernel for IXDP425 currently includes the machine descriptors
for IXDP465 and PRPMC1100 even if those machines are not configured.
This means we can build a kernel that boots on those machines even
though the machine_is_xxx() macro will always return 0 and other bits
such as PCI won't be compiled in. This can lead to many wasted hours
wondering what you have done to your kernel to make it randomly crash
thus requireing large quantities of beer to be consumed. While I am
all for consumption of large quantities of beer, there are better
reasons to do so then stupid kernel bugs.

Subject: [PATCH 121/855] [SCSI] SCSI scanning and removal fixes
This patch (as545) fixes the list traversals in __scsi_remove_target and
scsi_forget_host. In each case the existing code list_for_each_entry_safe
in an _unsafe_ manner, because the list was not protected from outside
modification while the iteration was running.
The new scsi_forget_host routine takes the moderately controversial step
of iterating over devices for removal rather than iterating over targets.
This makes more sense to me because the current scheme treats targets as
second-class citizens, created and removed on demand, rather than as
objects corresponding to actual hardware. (Also I couldn't figure out any
safe way to iterate over the target list, since it's not so easy to tell
when a target has already been removed.)

Subject: [PATCH 127/855] [PATCH] IPoIB: Fix SA client retransmission strategy
We got a little mixed up with what the backoff member holds in the
IPoIB multicast group structure: sometimes it was used as a number of
seconds, and sometimes it was used as a number of jiffies. Fix the
code so that backoff is always in seconds.

Subject: [PATCH 128/855] [PATCH] IB/mthca: Initialize eq->nent before we use
it
In mthca_create_eq(), we call get_eqe() before setting eq->nent. This
is wrong, because get_eqe() uses eq->nent. Fix this, and clean up the
code a little while we're at it. (We got lucky with the current code,
because eq->nent was cleared to 0, which get_eqe() made happen to do
the right thing)

Subject: [PATCH 133/855] [SCSI] fix oops on usb storage device disconnect
We fix the oops by enforcing the host state model. There have also
been two extra states added: SHOST_CANCEL_RECOVERY and
SHOST_DEL_RECOVERY so we can take the model through host removal while
the recovery thread is active.

Subject: [PATCH 134/855] [SCSI] Fix thread termination for the SCSI error
handle
From: Alan Stern <stern@rowland.harvard.edu>
This patch (as561) fixes the error handler's thread-exit code. The
kthread_stop call won't wake the thread from a down_interruptible, so
the patch gets rid of the semaphore and simply does
set_current_state(TASK_INTERRUPTIBLE);
Signed-off-by: Alan Stern <stern@rowland.harvard.edu>
Modified to simplify the termination loop and correct the sleep condition.

Subject: [PATCH 135/855] [PATCH] IB/mthca: Don't try to set srq->last for
userspace SRQs
Userspace SRQs don't have a buffer allocated for them in the kernel, so
it doesn't make sense to set srq->last during initialization. In fact,
this can crash trying to follow a nonexistent buffer pointer.

Subject: [PATCH 136/855] [PATCH] Alpha: ISA IRQs fixup for dp264
Basically, this extends original dp264 fixup to all dp264 variations.
Here is one minor change: mask out bits 4-7 of a value assigned by SRM,
because
- newer consoles report ISA IRQs with offset 0xe0;
- even if console IRQ value is bogus, we'll have a value < 16
so it should be harmless as it won't clash with native IRQs.
Particularly this fixes USB interrupt problem on xp1000 and es40.

Subject: [PATCH 137/855] [SCSI] fusion core changes for SAS support
- various bits for SAS support from the LSI driver.
- use the device private data for the fusion target private data.
this should be using the midlayer target data framework, but we
can't move over to that until fusion has been switched to the
generic DV code
- use target ID and channel from the fusion target private data,
because those in scsi_device will be different for mptsas

From 0c33b27deb93178f10778b3d2669af1674793cef Mon Sep 17 00:00:00 2001
From: Christoph Hellwig <hch@lst.de>
Date: Fri, 9 Sep 2005 16:27:19 +0200
Subject: [PATCH 138/855] [SCSI] fusion SAS support (mptsas driver)
Adds the actual mptsas driver, based upon the LSI driver with new work
for SAS transport class integration from Eric Moore and me.
This obviously depends on the SAS transport class.

Subject: [PATCH 139/855] [SCSI] fusion SAS support (mptsas driver) updates
Summary of Changes:
* splitting mpt_interrupt per Christophs suggestion
about a month ago
* rename ScsiCfgData to SpiCfgData structure,
then move all the raid related info into
new structure called RaidCfgData. This is
done because SAS supports RAID, as well as SPI,
so the raid stuff should be seperate.
* incorrect timeout calculation for cntdn
inside WaitForDoorbellAck and WaitForDoortbellInt
* add support for interpreting SAS Log Info
* Increase Event Log Size from 0xA to 0x32
* Fix bug in mptsas/mptfc/mptspi - when controller
has Initiator Mode Disabled, and only running in
TargetMode, the mptctl would panic when loading.
The fix is to return 0, instead of -ENODEV, in
SCSI LLD respective probe routines
* Fix bug in mptlan.c - driver will panic if
there is host reset, due to dev being set to
zero in mpt_lan_ioc_reset
* Fix's for SPI - Echo Buffer
* Several fix's in mptscsih_io_done - FCP Response
info, RESIDUAL_MISMATCH, Data Underrun, etc.
* Cleanup Error Handling - EH handlers,
mptscsih_flush_cmds, and zeroing out ScsiLookup
from mptscsih_qcmd
* Cleanup asyn event handling from
mptscsih -> mptscsih_event_process. Also
added support for SAS Persistent Table Full,
an asyn event

Subject: [PATCH 141/855] [SCSI] zfcp: fix race conditions when accessing
erp_action lists
o always use locking when changing erp_action lists,
o avoid escalation to ERP_ACTION_REOPEN_PORT_FORCED if erp_action is
still in use for ERP_ACTION_REOPEN_PORT

Subject: [PATCH 142/855] [SCSI] zfcp: remove union zfcp_req_data, use unit
refcount for FCP commands
o union zfcp_req_data removed
o increment unit refcount when processing FCP commands
(This fixes a theoretical race: When all scsi commands of a unit
are aborted and the scsi_device is removed then the unit could be
removed before all fsf_requests of that unit are completely processed.)

Subject: [PATCH 145/855] [SCSI] zfcp: enhancement of zfcp debug features
Debug features (DBFs) els_dbf, cmd_dbf and abt_dbf were removed and
san_dbf, hba_dbf and scsi_dbf were introduced. The erp_dbf did not
change.
The new traces improve debugging of problems with zfcp, scsi-stack,
multipath and hardware in the SAN. san_dbf traces things like ELS and
CT commands, hba_dbf saves HBA specific information of requests, and
scsi_dbf saves FCP and SCSI specific information of requests. Common
to all new DBFs is that they provide a so called structured view. This

From aef4a983090fa590481a86d9690dc3fa6bb121fa Mon Sep 17 00:00:00 2001

Date: Tue, 13 Sep 2005 21:51:16 +0200
Subject: [PATCH 146/855] [SCSI] zfcp: provide support for NPIV
N_Port ID Virtualization (NPIV) allows a single FCP port to appear as
multiple, distinct ports providing separate port identification. NPIV
is supported by FC HBAs on System z9. zfcp was adapted to support this
new feature.

From 13e1e1f08c1c098c7574c1fa72bd8c67792dc89b Mon Sep 17 00:00:00 2001
From: Andreas Herrmann <aherrman@de.ibm.com>
Date: Mon, 19 Sep 2005 16:56:17 +0200
Subject: [PATCH 147/855] [SCSI] zfcp: add additional fc_host attributes
this patch adds some fc host attributes and removes its equivalents
from the zfcp_adapter structure and zfcp specific sysfs subtree.
Furthermore it removes superfluous calls to fc_remort_port_delete when
an adapter is set offline because rports will be removed by
fc_remove_host anyway.

+/*
+ * ip_conntrack_pptp.c - Version 3.0
+ *
+ * Connection tracking support for PPTP (Point to Point Tunneling Protocol).
+ * PPTP is a a protocol for creating virtual private networks.
+ * It is a specification defined by Microsoft and some vendors
+ * working with Microsoft. PPTP is built on top of a modified
+ * version of the Internet Generic Routing Encapsulation Protocol.
+ * GRE is defined in RFC 1701 and RFC 1702. Documentation of
+ * PPTP can be found in RFC 2637
+ *
+ * (C) 2000-2005 by Harald Welte <laforge@gnumonks.org>
+ *
+ * Development of this code funded by Astaro AG (http://www.astaro.com/)
+ *
+ * Limitations:
+ * - We blindly assume that control connections are always
+ * established in PNS->PAC direction. This is a violation
+ * of RFFC2673
+ * - We can only support one single call within each session
+ *
+ * TODO:
+ * - testing of incoming PPTP calls
+ *
+ * Changes:
+ * 2002-02-05 - Version 1.3
+ * - Call ip_conntrack_unexpect_related() from
+ * pptp_destroy_siblings() to destroy expectations in case
+ * CALL_DISCONNECT_NOTIFY or tcp fin packet was seen
+ * (Philip Craig <philipc@snapgear.com>)
+ * - Add Version information at module loadtime
+ * 2002-02-10 - Version 1.6
+ * - move to C99 style initializers
+ * - remove second expectation if first arrives
+ * 2004-10-22 - Version 2.0

+ *
+ * It has an optional key field, which may help us distinguishing two
+ * connections between the same two hosts.
+ *
+ * GRE is defined in RFC 1701 and RFC 1702, as well as RFC 2784
+ *
+ * PPTP is built on top of a modified version of GRE, and has a mandatory
+ * field called "CallID", which serves us for the same purpose as the key
+ * field in plain GRE.
+ *
+ * Documentation about PPTP can be found in RFC 2637

Subject: [PATCH 152/855] [NETFILTER] ip6tables: remove duplicate code
Some IPv6 matches have very similar loops to find IPv6 extension header
and we can unify them. This patch introduces ipv6_find_hdr() to do it.
I just checked that it can find the target headers in the packet which has
dst,hbh,rt,frag,ah,esp headers.

Subject: [PATCH 153/855] [NETFILTER]: Rename misnamed function
Both __ip_conntrack_expect_find and ip_conntrack_expect_find_get take
a reference to the expectation, the difference is that callers of
__ip_conntrack_expect_find must hold ip_conntrack_lock.

Subject: [PATCH 157/855] [TCP]: Handle SACK'd packets properly in
tcp_fragment().
The problem is that we're now calling tcp_fragment() in a context
where the packets might be marked as SACKED_ACKED or SACKED_RETRANS.
This was not possible before as you never retransmitted packets that
are so marked.
Because of this, we need to adjust sacked_out and retrans_out in
tcp_fragment(). This is exactly what the following patch does.
We also need to preserve the SACKED_ACKED/SACKED_RETRANS marking
if they exist.

Fix unchecked __get_user that could be tricked into generating a
memory read on an arbitrary address. The result of the read is not
returned directly but you may be able to divine some information about
it, or use the read to cause a crash on some architectures by reading
hardware state. CAN-2004-2492.
Fix from Al Viro, ack from Dave Miller.

Subject: [PATCH 160/855] [SPARC64]: Handle little-endian unaligned
loads/stores correctly.
Because we use byte loads/stores to cons up the value
in and out of registers, we can't expect the ASI endianness
setting to take care of this for us. So do it by hand.
This case is triggered by drivers/block/aoe/aoecmd.c in the
ataid_complete() function where it goes:
/* word 100: number lba48 sectors */
ssize = le64_to_cpup((__le64 *) &id[100<<1]);
This &id[100<<1] address is 4 byte, rather than 8 byte aligned,
thus triggering the unaligned exception.

Subject: [PATCH 171/855] [ARM] Prevent deadlock in page fault handler
As per x86, we may deadlock while trying to get the mmap semaphore.
Implement the same fix, which allows (eg) recursive faults to cause
an oops instead of deadlocking.

Subject: [PATCH 172/855] [PATCH] IPoIB: Don't flush workqueue from within
workqueue
ipoib_mcast_restart_task() is always called from within the
single-threaded IPoIB workqueue, so flushing the workqueue from within
the function can lead to a recursion overflow. But since we're
running in a single-threaded workqueue, we're already synchronized
against other items in the workqueue, so just get rid of the flush in
ipoib_mcast_restart_task().

Subject: [PATCH 179/855] [AF_PACKET]: Allow for > 8 byte hardware addresses.
The convention is that longer addresses will simply extend
the hardeware address byte arrays at the end of sockaddr_ll and
packet_mreq.
In making this change a small information leak was also closed.
The code only initializes the hardware address bytes that are
used, but all of struct sockaddr_ll was copied to userspace.
Now we just copy sockaddr_ll to the last byte of the hardware
address used.
For error checking larger structures than our internal
maximums continue to be allowed but an error is signaled if we can
not fit the hardware address into our internal structure.

Subject: [PATCH 181/855] [TCP]: Set default congestion control correctly for
incoming connections.
Patch from Joel Sing to fix the default congestion control algorithm
for incoming connections. If a new congestion control handler is added
(via module), it should become the default for new
connections. Instead, the incoming connections use reno. The cause is
incorrect initialisation causes the tcp_init_congestion_control()
function to return after the initial if test fails.

Subject: [PATCH 183/855] [SPARC] cs4231: Fix SBUS support in this driver.
From: Christopher Zimmermann <madroach@zakweb.de>
This patch enables SBus support for the cs4231 sound driver.
It is tested on an Ultra2. Capture and playback both work.
I experienced lags and crashes using certain threaded
players like ogg123 and mp3blaster, while the former is
lagging far more. This behavior may be specific to SMP
systems. It is reproducable using the dummy sound card
driver. Sox works flawlessly.
Setting up the calculation of ptr in snd_cs4231_playback_pointer
was a bit strange. I got it to work by not incrementing the
[pc]_periods_sent counter when starting DMA the first time
in cs4231_dma_trigger. Therefore this dummy thing.
[ I did some minor cleanups -DaveM ]

Subject: [PATCH 184/855] [PATCH] ppc64: Fix PCI flags when using OF device
tree
My code to set up the PCI tree from the Open Firmware device tree was
setting IORESOURCE_* flags on the resources for the devices, but not
the PCI_BASE_ADDRESS_* flags. This meant that some drivers
misbehaved, and /proc/pci showed the wrong types for the resources.
This fixes it.

When the main thread of a thread group has done pthread_exit() and died,
the other threads are still happily running, but will not be visible
under /proc because their leader is no longer accessible.
This fixes the access control so that we can see the sub-threads again.

Subject: [PATCH 186/855] [PATCH] Add printk_clock()
ia64's sched_clock() accesses per-cpu data which isn't set up at boot time.
Hence ia64 cannot use printk timestamping, because printk() will crash in
sched_clock().
So make printk() use printk_clock(), defaulting to sched_clock(), overrideable
by the architecture via attribute(weak).

Subject: [PATCH 187/855] [PATCH] PPC64: Fix boot for some pre-POWER4 systems
Some RS64 systems (such as F80) have non-python host bridges with EADS.
However, they have two EADS with 4 buses each under them, so the old logic
that assumed no more than 7 busses per PHB failed miserably.
Big thanks to Olaf Hering for helping me test this, he's got one of the few
machines that broke from the previous logic.
Also, to be a bit smarter at detecting the need for a PHB-level IOMMU table
by checking for the presence of an ISA bus. Only PHBs with ISA bridges
should need the PHB-level table.

Subject: [PATCH 191/855] [PATCH] ppc64: Build zImage.vmode for G5
zImage.vmode was recently added. It's a version of zImage in which the ELF
note section used by open firmware indicates that it requires a virtual
mode instance of OF instead of real mode. This allows it to work with
Apple OF, and thus is directly bootable (or netbootable) from OF command
line. (Unfortunately, pSeries OF sort-of requires real mode and Apple OF
sort-of requires virtual mode, and both tend to be unhappy if no notes
section specifies the mode at all).
However, we forgot to add zImage.vmode to the default G5 build. This
fixes it.

Subject: [PATCH 201/855] [PATCH] fat: fix adate
During a forensic analysis on the fat file system, I found than the result for
the last access date on this file system was different between the stat
command and the istat command (package tct-utils).
The istat command display a true date (the right windows date) but the stat
primitive (so stat, find, ls command) displays a wrong date.

Follow up to 4732efbeb997189d9f9b04708dc26bf8613ed721 - uml must just reuse
as-is the backing architecture support. There is a micro-fixup is needed for the
included file, which won't affect i386 behaviour at all.
I've not tested compilation on x86_64, only on x86, but the code is almost the
same except the culprit test, so everything should be ok on x86_64 too.

Subject: [PATCH 207/855] [PATCH] Remove unused var from asm/futex.h
As recently done by Russell King for ARM, commit
4732efbeb997189d9f9b04708dc26bf8613ed721 introduces a generic asm/futex.h copied
along most arches, which includes a "-ENOSYS support" to be changed if needed.
However, it includes an unused var (taken from the "real" version) which GCC
warns about.
Remove it from all arches having that file version (i.e. same GIT id).
$ git-diff-tree -r HEAD
and
$ git-ls-tree -r HEAD include/|grep 9feff4ce1424bc390608326240be369eb13aa648
may be more interesting than looking at the patch itself, to make sure I've
just copied the arm header to all other archs having the original dummy version
of this file.

I am a lamer :-(. Luckily, Luo Xin performed LTP testing and found this failure.
Btw, the fact that the patch in which I introduced this was merged shows that:
a) I'm really trusted by people
b) sometimes they're wrong about point a).
c) lack of time for reviewers.

Subject: [PATCH 212/855] [PATCH] uml: fix bogus HOST_ELF_CLASS symbol name
Even if with a bit of misunderstanding, Al fixed this in commit
95608261dae863bc43292e6fbd946a3abd3aa49f.
Well, the symbol was intended to come from userspace (it exists there on normal
host), but since some hosts may miss that, using the kernel one is just as fine.
However, rename it to be named consistently with the rest.
Actually, he missed converting ELFCLASS32 to coming from kernel headers. For
consistence, add ELFCLASS64 too.

Readd this header (deleted in 60d339f6fe0831060600c62418b71a62ad26c281). A
warning is spit out here about undeclared getpgrp().

Subject: [PATCH 214/855] [PATCH] uml: comment about cast build fix
Explain why the casting we do to silence this warning is indeed safe.
It is because the field we're casting from, though being 64-bit wide, was filled
with a pointer in first place by ourselves.

Subject: [PATCH 215/855] [PATCH] uml: fix compile warning after consolidation
patch
The header declaring this function wasn't included, so the function declaration
was totally bogus wrt. the proto - even if this wasn't going to fail at all.
It was so bad that the compile warning I got was "control reaches end of
non-void function", i.e. missing return. Actually, this has been there for ages,
the consolidation patch just added the warning which was needed to clean it up.
Nice. Really.

Fix bond_enslave link monitoring warning to check use_carrier status

as well as do_ioctl, and also uses the per-bond params.use_carrier
instead of the global use_carrier.

Subject: [PATCH 219/855] [PATCH] skge: expand ethtool debug register dump
Expand the returned data for ethtool debug access to include
all of the mapped PCI area; except for the small set of registers
that are for diagnostic RAM access. Access to those registers
will hang the system.

Subject: [PATCH 223/855] [SPARC64]: Remove ktlb.S instruction patching.
This was kind of ugly, and actually buggy. The bug was that
we didn't handle a machine with memory starting > 4GB. If
the 'prompmd' was allocated in physical memory > 4GB we'd
croak because the obp_iaddr_patch and obp_daddr_patch things
only supported a 32-bit physical address.
So fix this by just loading the appropriate values from two
variables in the kernel image, which is locked into the TLB
and thus accesses to them can't cause a recursive TLB miss.

Subject: [PATCH 225/855] [LLC]: Make llc_frame_alloc take a net_device as an
argument
So as to set the newly created sk_buff ->dev member with it, that way we stop
using dev_base->next, that is the wrong thing to do, as there may well be
several interfaces being used with LLC. This was not such a big problem after
all as most of the users of llc_alloc_frame were setting the correct dev, but
this way code is reduced.
This also fixes another bug in llc_station_ac_send_null_dsap_xid_c, that was
not setting the skb->dev field.

Subject: [PATCH 234/855] [SPARC64]: Break up inherit_prom_mappings() into it's
constituent parts.
This thing was just a huge monolithic mess, so chop it up.

Subject: [PATCH 244/855] [SPARC64]: Do not allocate OBP page tables using
bootmem
Just allocate them physically starting from the end of
the kernel image. This incredibly simplifies our MM
bootstrap in that we don't need any mappings in the linear
PAGE_OFFSET area working in order to bootstrap ourselves and
take over the trap table from the firmware.
Many further simplifications are possible now, and this also
sets the stage for CONFIG_DEBUG_PAGEALLOC support.

Subject: [PATCH 248/855] [SPARC64]: Remove unnecessary paging_init() cruft.
Because we don't access the PAGE_OFFSET linear mappings
any longer before we take over the trap table from the
firmware, we don't need to load dummy mappings there
into the TLB and we don't need the bootmap_base hack
any longer either.
While we are here, check for a larger than 8MB kernel
and halt the boot with an error message. We know that
doesn't work, so instead of failing mysteriously we
should let the user know exactly what's wrong.

Borrowing the structure of TCP/IP for this. On the receive of new connections I
was bh_lock_socking the _new_ sock, not the listening one, duh, now it survives
the ssh connections storm I've been using to test this specific bug.
Also fixes send side skb sock accounting.

Subject: [PATCH 251/855] [LLC]: fix llc_ui_recvmsg, making it behave like
tcp_recvmsg
In fact it is an exact copy of the parts that makes sense to LLC :-)

Subject: [PATCH 253/855] [PATCH] Driver Core: fis bus rescan devices race
bus_rescan_devices_helper() does not hold the dev->sem when it checks for
!dev->driver(). device_attach() holds the sem, but calls again
device_bind_driver() even when dev->driver is set.
What happens is that a first device_attach() call (module insertion time)
is on the way binding the device to a driver. Another thread calls
bus_rescan_devices(). Now when bus_rescan_devices_helper() checks for
dev->driver it is still NULL 'cos the the prior device_attach() is not yet
finished. But as soon as the first one releases the dev->sem the second
device_attach() tries to rebind the already bound device again.
device_bind_driver() does this blindly which leads to a corrupt
driver->klist_devices list (the device links itself, the head points to the
device). Later a call to device_release_driver() sets dev->driver to NULL
and breaks the link it has to itself on knode_driver. Rmmoding the driver
later calls driver_detach() which leads to an endless loop 'cos the list
head in klist_devices still points to the device. And since dev->driver is
NULL it's stuck with the same device forever. Boom. And rmmod hangs.
Very easy to reproduce with new-style pcmcia and a 16bit card. Just loop
modprobe <pcmcia-modules> ;cardctl eject; rmmod <card driver, pcmcia
modules>.
Easiest fix is to check if the device is already bound to a driver in
device_bind_driver(). This avoids the double binding.

Subject: [PATCH 255/855] [PATCH] fix class symlinks in sysfs
The class symlinks in sysfs don't properly handle changing device names.
To demonstrate, rename your network device from eth0 to eth1. Your
pci (or usb, or whatever) device will still have a 'net:eth0' link,
except now it points to /sys/class/net/eth1.
The attached patch makes sure the class symlink name changes when
the class device name changes. It isn't 100% correct, it should be
using sysfs_rename_link. Unfortunately, sysfs_rename_link doesn't exist.

Subject: [PATCH 259/855] [PATCH] fix drivers/pci/probe.c warning
This function expects an unsigned 32-bit type as its third argument:
static u32 pci_size(u32 base, u32 maxbase, u32 mask)
However, given these definitions:
#define PCI_BASE_ADDRESS_MEM_MASK (~0x0fUL)
#define PCI_ROM_ADDRESS_MASK (~0x7ffUL)
these two calls in drivers/pci/probe.c are problematic for architectures
for which a UL is not equivalent to a u32:
sz = pci_size(l, sz, PCI_BASE_ADDRESS_MEM_MASK);
sz = pci_size(l, sz, PCI_ROM_ADDRESS_MASK);
Hence the below compile warning when building for ARCH=ppc64:
drivers/pci/probe.c: In function `pci_read_bases':
/.../probe.c:168: warning: large integer implicitly truncated to unsigned type
/.../probe.c:218: warning: large integer implicitly truncated to unsigned type
Here is a simple fix.

- Bump UB_MAX_REQ_SG, this allows to burn CDs
- Drop initialization of urb.transfer_flags,
now that URB_UNLINK_ASYNC is gone
- Add forgotten processing of stalls at GetMaxLUN
- Remove a few more P3-tagged printks whose time has come
- Correct comment about ZIP-100

Subject: [PATCH 263/855] [PATCH] USB: ftdi_sio: allow baud rate to be changed
without raising RTS and DTR
I'm using a 2 port USB RS232 dongle to connect to a serial-IR cradle for
a bar code reader). Detecting the baudrate of the serial-IR involves
keeping DTR low while changing baudrate.
This works using normal 16550A serial ports as well as the FTDI driver
version 1.4.0 (Linux 2.6.8) but stopped working with the change to
"ensure RTS and DTR are raised when changing baudrate" introduced in
version 1.4.1 (Linux 2.6.9).
The attached patch fixes this, so RTS and DTR is only raised when
changing baudrate iff the previous baudrate was B0.

Subject: [PATCH 265/855] [PATCH] USB: sl811-hcd minor fixes
Three minor sl811-hcd fixes:
- Elminate memory leak on one (rare) disable/shutdown path.
- For periodic transfers that don't need to be scheduled, update
urb->start_frame to represent the transfer phase correctly.
- Report the (single) port as removable, by default.
Since no drivers yet use start_frame or that part of the hub descriptor,
only that leak is likely to ever matter.

Subject: [PATCH 266/855] [PATCH] USB: fix pegasus driver
Addresses some small bugs in the pegasus ethernet-over-USB driver.
Specifically, malformed long packets from the adapter could cause a kernel
panic; the interrupt interval calculation was inappropriate for high-speed
devices; the return code from read_mii_word was tested incorrectly; and
failure to unlink outstanding URBs before freeing them could lead to kernel
panics when unloading the driver.

Wire the MCA/INIT handler stacks into DTR[2] and track them in
IA64_KR(CURRENT_STACK). This gives the MCA/INIT handler stacks the
same TLB status as normal kernel stacks. Reload the old CURRENT_STACK

Subject: [PATCH 276/855] [SPARC64]: Rewrite bootup sequence.
Instead of all of this cpu-specific code to remap the kernel
to the correct location, use portable firmware calls to do
this instead.
What we do now is the following in position independant
assembler:
chosen_node = prom_finddevice("/chosen");
prom_mmu_ihandle_cache = prom_getint(chosen_node, "mmu");
vaddr = 4MB_ALIGN(current_text_addr());
prom_translate(vaddr, &paddr_high, &paddr_low, &mode);
prom_boot_mapping_mode = mode;
prom_boot_mapping_phys_high = paddr_high;
prom_boot_mapping_phys_low = paddr_low;
prom_map(-1, 8 * 1024 * 1024, KERNBASE, paddr_low);
and that replaces the massive amount of by-hand TLB probing and
programming we used to do here.
The new code should also handle properly the case where the kernel
is mapped at the correct address already (think: future kexec
support).
Consequently, the bulk of remap_kernel() dies as does the entirety
of arch/sparc64/prom/map.S
We try to share some strings in the PROM library with the ones used
at bootup, and while we're here mark input strings to oplib.h routines
with "const" when appropriate.
There are many more simplifications now possible. For one thing, we
can consolidate the two copies we now have of a lot of cpu setup code
sitting in head.S and trampoline.S.
This is a significant step towards CONFIG_DEBUG_PAGEALLOC support.

Subject: [PATCH 279/855] [PATCH] reboot: comment and factor the main reboot
functions
In the lead up to 2.6.13 I fixed a large number of reboot problems by
making the calling conventions consistent. Despite checking and double
checking my work it appears I missed an obvious one.
This first patch simply refactors the reboot routines so all of the
preparation for various kinds of reboots are in their own functions.
Making it very hard to get the various kinds of reboot out of sync.

Subject: [PATCH 280/855] [PATCH] suspend: cleanup calling of power off
methods.
In the lead up to 2.6.13 I fixed a large number of reboot problems by
making the calling conventions consistent. Despite checking and double
checking my work it appears I missed an obvious one.
The S4 suspend code for PM_DISK_PLATFORM was also calling device_shutdown
without setting system_state, and was not calling the appropriate
reboot_notifier.
This patch fixes the bug by replacing the call of device_suspend with
kernel_poweroff_prepare.
Various forms of this failure have been fixed and tracked for a while.
Thanks for tracking this down go to: Alexey Starikovskiy, Meelis Roos

Ossman <drzeus-list@drzeus.cx>

Subject: [PATCH 282/855] [PATCH] v9fs: make conv functions to check for conv
buffer overflow
buf_check_size function checks if the conv buffer has enough space for the
performed operation, but it doesn't return the result back to the calling
function, only logs an error in the log.
The report-back-error functionality was lost when buf_check_size was
converted from macro to inline function. The return in the macro used to
exit from the functions that include it, after the conversion it just exits
from the inline function itself.
The patch makes buf_check_size to return flag and all functions that use
it check if they should perform the operation, or exit.

Subject: [PATCH 284/855] [PATCH] v9fs: make copy of the transport prototype
instead of using it directly
When a new session is created it uses a template object of the specified
transport type to instantiate its own copy. The code for the making a copy of
the template object was lost, and the object itself is attached to the v9fs
session. This leads to many sessions using the same transport instead of
having their own copy.
The patch puts back the code that makes a copy of the template object.

__getname buffers to PATH_MAX
v9fs_vfs_readlink allocates space for the link using __getname and
errorneously uses strlen on the newly allocated buffer to check if the buffer
passed by the user is bigger than the one returned by __getname.
The patch replaces the strlen usage to PATH_MAX, which is the actual size of
the buffers returned by __getname.

Subject: [PATCH 286/855] [PATCH] v9fs: don't free root dentry & inode if error
occurs in v9fs_get_sb
If error occurs while in v9fs_get_sb after it calles sget, the dentry object
of the root and its inode may be freed twice -- once while handling the error
in v9fs_get_sb, and second time when v9fs_get_sb calles deactivate_super
(which in turn calls v9fs_kill_super)
The patch removes the unnecessary code that frees the root dentry and its
inode.

Subject: [PATCH 293/855] [PATCH] Fix mmap() of /dev/hpet
The address passed to io_remap_pfn_range() in hpet_mmap() does not need to
be converted using __pa(): it is already a physical address. This bug was
found and the patch suggested by Clay Harris.
I introduced this particular bug when making io_remap_pfn_range changes a
few months ago. In fact mmap()ing /dev/hpet has *never* previously worked:
before my changes __pa() was being executed on an ioremap()ed virtual
address, which is also invalid.

Subject: [PATCH 296/855] [PATCH] slab: fix handling of pages from foreign NUMA
nodes
The numa slab allocator may allocate pages from foreign nodes onto the
lists for a particular node if a node runs out of memory. Inspecting the
slab->nodeid field will not reflect that the page is now in use for the
slabs of another node.
This patch fixes that issue by adding a node field to free_block so that
the caller can indicate which node currently uses a slab.
Also removes the check for the current node from kmalloc_cache_node since
the process may shift later to another node which may lead to an allocation
on another node than intended.

Subject: [PATCH 298/855] [PATCH] ppc64: Fix LPAR regression
The recent iommu fix broke booting on some POWER4 and POWER5 LPAR boxes.
It looks like we have been calling the non LPAR iommu_dev_setup on LPAR
machines for a while. The recent iommu fix caused that code path to
fail.
It looks like we just need to hook up the devices iommu_table to the
parents one, so do that instead of calling iommu_dev_setup_pSeries and
crossing the streams.

Subject: [PATCH 301/855] [PATCH] ppc64: SMU driver update & i2c support
The SMU is the "system controller" chip used by Apple recent G5 machines
including the iMac G5. It drives things like fans, i2c busses, real time
clock, etc...
The current kernel contains a very crude driver that doesn't do much more
than reading the real time clock synchronously. This is a completely
rewritten driver that provides interrupt based command queuing, a userland
interface, and an i2c/smbus driver for accessing the devices hanging off
the SMU i2c busses like temperature sensors. This driver is a basic block
for upcoming work on thermal control for those machines, among others.

+ * i2c commands
+ *
+ * To issue an i2c command, first is to send a parameter block to the
+ * the SMU. This is a command of type 0x9a with 9 bytes of header
+ * eventually followed by data for a write:
+ *
+ * 0: bus number (from device-tree usually, SMU has lots of busses !)
+ * 1: transfer type/format (see below)
+ * 2: device address. For combined and combined4 type transfers, this
+ * is the "write" version of the address (bit 0x01 cleared)
+ * 3: subaddress length (0..3)
+ * 4: subaddress byte 0 (or only byte for subaddress length 1)
+ * 5: subaddress byte 1
+ * 6: subaddress byte 2
+ * 7: combined address (device address for combined mode data phase)
+ * 8: data length
+ *
+ * The transfer types are the same good old Apple ones it seems,
+ * that is:
+ * - 0x00: Simple transfer
+ * - 0x01: Subaddress transfer (addr write + data tx, no restart)
+ * - 0x02: Combined transfer (addr write + restart + data tx)
+ *
+ * This is then followed by actual data for a write.
+ *
+ * At this point, the OF driver seems to have a limitation on transfer
+ * sizes of 0xd bytes on reads and 0x5 bytes on writes. I do not know
+ * wether this is just an OF limit due to some temporary buffer size
+ * or if this is an SMU imposed limit. This driver has the same limitation
+ * for now as I use a 0x10 bytes temporary buffer as well
+ *
+ * Once that is completed, a response is expected from the SMU. This is
+ * obtained via a command of type 0x9a with a length of 1 byte containing
+ * 0 as the data byte. OF also fills the rest of the data buffer with 0xff's
+ * though I can't tell yet if this is actually necessary. Once this command
+ * is complete, at this point, all I can tell is what OF does. OF tests
+ * byte 0 of the reply:
+ * - on read, 0xfe or 0xfc : bus is busy, wait (see below) or nak ?
+ * - on read, 0x00 or 0x01 : reply is in buffer (after the byte 0)
+ * - on write, < 0 -> failure (immediate exit)
+ * - else, OF just exists (without error, weird)
+ *
+ * So on read, there is this wait-for-busy thing when getting a 0xfc or
+ * 0xfe result. OF does a loop of up to 64 retries, waiting 20ms and
+ * doing the above again until either the retries expire or the result
+ * is no longer 0xfe or 0xfc
+ *
+ * The Darwin I2C driver is less subtle though. On any non-success status
+ * from the response command, it waits 5ms and tries again up to 20 times,
+ * it doesn't differenciate between fatal errors or "busy" status.
+ *
+ * This driver provides an asynchronous paramblock based i2c command
+ * interface to be used either directly by low level code or by a higher
+ * level driver interfacing to the linux i2c layer. The current
+ * implementation of this relies on working timers & timer interrupts
+ * though, so be careful of calling context for now. This may be "fixed"
+ * in the future by adding a polling facility.

Subject: [PATCH 305/855] [PATCH] __kmalloc: Generate BUG if size requested is
too large.
I had an issue on ia64 where I got a bug in kernel/workqueue because
kzalloc returned a NULL pointer due to the task structure getting too big
for the slab allocator. Usually these cases are caught by the kmalloc
macro in include/linux/slab.h.
Compilation will fail if a too big value is passed to kmalloc.
However, kzalloc uses __kmalloc which has no check for that. This patch
makes __kmalloc bug if a too large entity is requested.

Only remove the UML pidfile and management socket if we created them.
Currently in case two UMLs are started with the same umid, the second will
remove the first's ones.
Probably we should also panic() at that point, not sure however.

Subject: [PATCH 310/855] [PATCH] uml: fix hang in TT mode on fault
The current code doesn't handle well general protection faults on the host -
it thinks that cr2 is always the address of a page fault. While actually, on
general protection faults, that address is not accessible, so we'd better
assume we couldn't satisfy the fault. Currently instead we think we've fixed
it, so we go back, retry the instruction and fault again endlessly.
This leads to the kernel hanging when doing copy_from_user(dest, -1, ...) in
TT mode, since reading *(-1) causes a GFP, and we don't support kernel
preemption.
Thanks to Luo Xin for testing UML with LTP and reporting the failures he got.

Subject: [PATCH 312/855] [PATCH] uml: run mconsole "sysrq" in process context
Things are breaking horribly with sysrq called in interrupt context. I want
to try to fix it, but probably this is simpler. To tell the truth, sysrq is
normally run in interrupt context, so there shouldn't be any problem.
There's also a warning from the fault handler because it's run in atomic
context (I have a patch for that, only I deferred it). This is why I'm doing
this.

Subject: [PATCH 313/855] [PATCH] uml: avoid fixing faults while atomic
Following i386, we should maybe refuse trying to fault in pages when we're
doing atomic operations, because to handle the fault we could need to take
already taken spinlocks.
Also, if we're doing an atomic operation (in the sense of in_atomic()) we're
surely in kernel mode and we're surely going to handle adequately the failed
fault, so it's safe to behave this way.
Currently, on UML SMP is rarely used, and we don't support PREEMPT, so this is
unlikely to create problems right now, but it might in the future.

setup_initial_poll is only called with sigio_lock() held, so use appropriate
allocation.
Also, parse_chan() can also be called when holding a spinlock (see line_open()
-> parse_chan_pair()).
I have sporadic problems (spinlock taken twice, with spinlock debugging on UP)
which could be caused by a sequence like "take spinlock, alloc and go to
sleep, take again the spinlock in the other thread".

printf - to report console failure
User get *a lot* confused when consoles don't work but we don't report
anything. And, as reported in the comment, using printk to report "your
console doesn't work" isn't likely to go that far.
Fix the problem on the base of this: stack consumption by host printf(). Use
kernel sprintf() and os_write_file, using a wild guess that one page will be
enough for the message, to preallocate the buffer with kmalloc().

Subject: [PATCH 320/855] [PATCH] Fix bd_claim() error code.
Problem: In some circumstances, bd_claim() is returning the wrong error
code.
If we try to swapon an unused block device that isn't swap formatted, we
get -EINVAL. But if that same block device is already mounted, we instead
get -EBUSY, even though it still isn't a valid swap device.
This issue came up on the busybox list trying to get the error message
from "swapon -a" right. If a swap device is already enabled, we get -EBUSY,
and we shouldn't report this as an error. But we can't distinguish the two
-EBUSY conditions, which are very different errors.
In the code, bd_claim() returns either 0 or -EBUSY, but in this case busy
means "somebody other than sys_swapon has already claimed this", and
_that_ means this block device can't be a valid swap device. So return
-EINVAL there.

+Device-mapper snapshot support
+==============================
+
+Device-mapper allows you, without massive data copying:
+
+*) To create snapshots of any block device i.e. mountable, saved states of
+the block device which are also writable without interfering with the
+original content;
+*) To create device "forks", i.e. multiple different versions of the
+same data stream.
+
+
+In both cases, dm copies only the chunks of data that get changed and
+uses a separate copy-on-write (COW) block device for storage.
+
+
+There are two dm targets available: snapshot and snapshot-origin.
+
+*) snapshot-origin <origin>
+
+which will normally have one or more snapshots based on it.
+You must create the snapshot-origin device before you can create snapshots.
+Reads will be mapped directly to the backing device. For each write, the
+original data will be saved in the <COW device> of each snapshot to keep
+its visible content unchanged, at least until the <COW device> fills up.
+
+
+*) snapshot <origin> <COW device> <persistent?> <chunksize>
+
+A snapshot is created of the <origin> block device. Changed chunks of
+<chunksize> sectors will be stored on the <COW device>. Writes will
+only go to the <COW device>. Reads will come from the <COW device> or
+from <origin> for unchanged data. <COW device> will often be
+smaller than the origin and if it fills up the snapshot will become
+useless and be disabled, returning errors. So it is important to monitor
+the amount of free space and expand the <COW device> before it fills up.
+
+<persistent?> is P (Persistent) or N (Not persistent - will not survive
+after reboot).
+
+
+How this is used by LVM2
+========================
+When you create the first LVM2 snapshot of a volume, four dm devices are used:

+1) a device containing the original mapping table of the source volume;
+2) a device used as the <COW device>;
+3) a "snapshot" device, combining #1 and #2, which is the visible snapshot

+4) the "original" volume (which uses the device number used by the original
+ source volume), whose table is replaced by a "snapshot-origin" mapping

+
+A fixed naming scheme is used, so with the following commands:

+lvcreate -L 100M --snapshot -n snap volumeGroup/base

Subject: [PATCH 323/855] [TCP]: Adjust Reno SACK estimate in tcp_fragment
Since the introduction of TSO pcount a year ago, it has been possible
for tcp_fragment() to cause packets_out to decrease. Prior to that,
tcp_retrans_try_collapse() was the only way for that to happen on the
retransmission path.
When this happens with Reno, it is possible for sasked_out to become
invalid because it is only an estimate and not tied to any particular
packet on the retransmission queue.
Therefore we need to adjust sacked_out as well as left_out in the Reno
case. The following patch does exactly that.
This bug is pretty difficult to trigger in practice though since you
need a SACKless peer with a retransmission that occurs just as the
cached MTU value expires.

Subject: [PATCH 328/855] [NETFILTER] Fix conntrack event cache deadlock/oops
This patch fixes a number of bugs. It cannot be reasonably split up in
multiple fixes, since all bugs interact with each other and affect the same
function:
Bug #1:
The event cache code cannot be called while a lock is held. Therefore, the
call to ip_conntrack_event_cache() within ip_ct_refresh_acct() needs to be
moved outside of the locked section. This fixes a number of 2.6.14-rcX
oops and deadlock reports.
Bug #2:
We used to call ct_add_counters() for unconfirmed connections without
holding a lock. Since the add operations are not atomic, we could race
with another CPU.
Bug #3:
ip_ct_refresh_acct() lost REFRESH events in some cases where refresh
(and the corresponding event) are desired, but no accounting shall be
performed. Both, evenst and accounting implicitly depended on the skb
parameter bein non-null. We now re-introduce a non-accounting
"ip_ct_refresh()" variant to explicitly state the desired behaviour.

Subject: [PATCH 330/855] [PATCH] 8390 Tx fix for non i386 machines
While this is true, E8390_CMD is zero on i386, and thus there should be no
effect for these machines. Machines like Mac, Amiga etc. which use Alan's
clever register mapping may have a non-zero E8390_CMD and result in bogus
"transmitter busy" type messages from this bug.
Fixes BUG# 3991.

Subject: [PATCH 332/855] [PATCH] pci: fixup parent subordinate busnr
I believe the change that broke things is introduction of
pci_fixup_parent_subordinate_busnr().
The patch here does two things:
- hunk #1 should fix the problems you've seen when you boot without
additional "pci" kernel options;
- hunk #2 supposedly fixes boot with "pci=assign-busses" option which
otherwise hangs Acer TM81xx machines as reported.
Please try this with and without "pci=assign-busses". If it boots,
I'd like to see 'lspci -vvx' for both cases.

Subject: [PATCH 336/855] Make sure SIGKILL gets proper respect
Bhavesh P. Davda <bhavesh@avaya.com> noticed that SIGKILL wouldn't
properly kill a process under just the right cicumstances: a stopped
task that already had another signal queued would get the SIGKILL
queued onto the shared queue, and there it would remain until SIGCONT.
This simplifies the signal acceptance logic, and fixes the bug in the
process.
Losely based on an earlier patch by Bhavesh.

Subject: [PATCH 339/855] [PATCH] ppc64: Fix huge pages MMU mapping bug
Current kernel has a couple of sneaky bugs in the ppc64 hugetlb code that
cause huge pages to be potentially left stale in the hash table and TLBs
(improperly invalidated), with all the nasty consequences that can have.
One is that we forgot to set the "secondary" bit in the hash PTEs when
hashing a huge page in the secondary bucket (fortunately very rare).
The other one is on non-LPAR machines (like Apple G5s), flush_hash_range()
which is used to flush a batch of PTEs simply did not work for huge pages.
Historically, our huge page code didn't batch, but this was changed without
fixing this routine. This patch fixes both.

We have to introduce a separate Kconfig menu entry for the NFQUEUE targets.
They cannot "just" depend on nfnetlink_queue, since nfnetlink_queue could
be linked into the kernel, whereas iptables can be a module.

Subject: [PATCH 350/855] [NET]: Protect neigh_stat_seq_fops by CONFIG_PROC_FS
From: Amos Waterland <apw@us.ibm.com>
If CONFIG_PROC_FS is not selected, the compiler emits this warning:
net/core/neighbour.c:64: warning: `neigh_stat_seq_fops' defined but not used
Which is correct, because neigh_stat_seq_fops is in fact only
initialized and used by code that is protected by CONFIG_PROC_FS. So
this patch fixes that up.

Subject: [PATCH 356/855] [SCSI] allow REPORT LUN scanning even for LUN 0 PQ of
3
Currently we just ignore the device, which means there are a few
arrays out there that we don't find.
This patch updates the scsi_report_lun_scan() to take a target instead
of a device so it can be called on a return of
SCSI_SCAN_TARGET_PRESENT, which is what a PQ 3 device returns.

Subject: [PATCH 357/855] [SCSI] qla2xxx: fix remote port timeout with qla2xxx
driver
This patch fixes a hole in the rport unblock handling when processing
fabric events via the ADISC/PLOGI device state machine. Original code
would not properly 'unblock' the port upon the port reloging into the
fabric.

Subject: [PATCH 361/855] [SPARC64]: Add CONFIG_DEBUG_PAGEALLOC support.
The trick is that we do the kernel linear mapping TLB miss starting
with an instruction sequence like this:
ba,pt %xcc, kvmap_load
xor %g2, %g4, %g5
succeeded by an instruction sequence which performs a full page table
walk starting at swapper_pg_dir.
We first take over the trap table from the firmware. Then, using this
constant PTE generation for the linear mapping area above, we build
the kernel page tables for the linear mapping.
After this is setup, we patch that branch above into a "nop", which
will cause TLB misses to fall through to the full page table walk.
With this, the page unmapping for CONFIG_DEBUG_PAGEALLOC is trivial.

Subject: [PATCH 362/855] [SPARC64]: Probe D/I/E-cache config and use.
At boot time, determine the D-cache, I-cache and E-cache size and
line-size. Use them in cache flushes when appropriate.
This change was motivated by discovering that the D-cache on
UltraSparc-IIIi and later are 64K not 32K, and the flushes done by the
Cheetah error handlers were assuming a 32K size.
There are still some pieces of code that are hard coding things and
will need to be fixed up at some point.
While we're here, fix the D-cache and I-cache parity error handlers
to run with interrupts disabled, and when the trap occurs at trap
level > 1 log the event via a counter displayed in /proc/cpuinfo.

Subject: [PATCH 365/855] [PATCH] yenta: auto-tune EnE bridges for CardBus
cards
Echo Audio cardbus products are known to be incompatible with EnE bridges.
in order to maybe solve the problem a EnE specific test bit has to be set,
another cleared...but other setups have a good chance to break when just
forcing the bits. so do the whole thingy automatically.
The patch adds a hook in cb_alloc() that allows special tuning for the
different chipsets. for ene just match the Echo products and set/clear the
test bits, defaults to do the same thing as w/o the patch to not break
working setups.

Subject: [PATCH 366/855] [PATCH] yenta: don't mess with bridge control
register
In interrupt probing (both ISA and PCI) the bridge control register is used
to change interrupt routing to ISA or PCI by changing bit 7. But this bit
only controls the routing of card functional interrupts, not the CSC
interrupts which are used for interrupt probing.
A bad side effect of messing with this register in yenta_probe_irq() is
that it can lead to irq storms if a card is inserted and already powered by
the BIOS.
Usage in yenta_sock_init() and yenta_config_init() seem to be fishy as well.

pci_set_power_state is not needed, as we call pci_enable_device() somewhere
else. Also, the resource we write to PCI_BASE_ADDRESS_0 needs to be converted
to bus-centric view first.

Subject: [PATCH 376/855] [IB] mthca: Fix doorbell record resource leak
If we allocate a bunch of doorbell records and then free them, we'll
end up with completely empty pages, which we then free. However, when
we come back to allocate more doorbell pages, we have to reallocate
those empty pages rather than always trying to take a slot that we've
never used. If we don't, we eventually use up every slot and fail to
allocate a doorbell record, even though we have plenty of free space.

Patch from Vincent Sanders
A recent patch which made IXP4xx mach_desc's depend on config options
had the effect of not building the kernel for several machines it
possibly could be, this patch updates the default config to ensure all
possible machines are built for by default.

From 63c47c286d062d93e0501d60797274c84a587e97 Mon Sep 17 00:00:00 2001
From: Roland Dreier <rolandd@cisco.com>
Date: Mon, 26 Sep 2005 13:01:03 -0700
Subject: [PATCH 381/855] [IB] uverbs: Close some exploitable races
Al Viro pointed out that the current IB userspace verbs interface
allows userspace to cause mischief by closing file descriptors before
we're ready, or issuing the same command twice at the same time. This
patch closes those races, and fixes other obvious problems such as a
module reference leak.
Some other interface bogosities will require an ABI change to fix
properly, so I'm deferring those fixes until 2.6.15.

If input message rate from userspace is too high, do not drop them,
but try to deliver using work queue allocation.
Failing there is some kind of congestion control.
It also removes warn_on on this condition, which scares people.

Subject: [PATCH 386/855] [NETFILTER]: Fix invalid module autoloading by
splitting iptable_nat
When you've enabled conntrack and NAT as a module (standard case in all
distributions), and you've also enabled the new conntrack netlink
interface, loading ip_conntrack_netlink.ko will auto-load iptable_nat.ko.
This causes a huge performance penalty, since for every packet you iterate
the nat code, even if you don't want it.
This patch splits iptable_nat.ko into the NAT core (ip_nat.ko) and the
iptables frontend (iptable_nat.ko). Threfore, ip_conntrack_netlink.ko will
only pull ip_nat.ko, but not the frontend. ip_nat.ko will "only" allocate
some resources, but not affect runtime performance.
This separation is also a nice step in anticipation of new packet filters
(nf-hipac, ipset, pkttables) being able to use the NAT core.

From 7a8cf29d69e077dfe90e327859201fd9b75a47ce Mon Sep 17 00:00:00 2001
From: Mark Haverkamp <markh@osdl.org>
Date: Thu, 22 Sep 2005 09:15:24 -0700
Subject: [PATCH 388/855] [SCSI] aacraid: Greater than 2TB capacity support
Received from Mark Salyzyn from Adaptec.
There are a few adapters that are capable of creating devices with this large
of a capacity, but now that we have the large fib support in, the management
applications will be capable of generating them. The problem is, once they are
created, the driver will not be able to access the devices correctly without
this patch.

Subject: [PATCH 390/855] [SCSI] aacraid: handle AIF hotplug events (update)
Received from Mark Salyzyn from Adaptec.
Hotplug sniffs the AIFs (events) from the adapter and if a container
change resulting in the device going offline (container zero), online
(container zero completed) or changing capacity (morph) it will take
actions by calling the appropriate API.

Subject: [PATCH 392/855] [SCSI] aacraid: initialization timeout
Received from Mark Salyzyn from Adaptec.
In the rare instances where the adapter, or the motherboard, is
misbehaving; driver initialization or shutdown becomes problematic. By
introducing a 3 minute timeout on the first interrupt driven command
during initialization, or the issuance of the adapter shutdown command
during driver unload, we can resolve the lockup problems induced by
common (but rare) hardware misbehaviors.
The timeout during initialization, should it occur, is accompanied by a
message presented to the console and the logs indicating that the user
should inspect and resolve problems with interrupt routing.

Subject: [PATCH 393/855] [SCSI] aacraid: fib size math fix
Received from Mark Salyzyn from Adaptec.
The size of the command packet's scatter gather list maximum size was
miscalculated in the low range leading to the driver initialization
limiting the maximum i/o size that could go to the Adapter. There were
no negative operational side effects resulting from this bad math, only
a subtle limit in performance of the Adapter at the top end of the
range.

Subject: [PATCH 394/855] [SCSI] aacraid: remove aac_insert_entry
Received from Mark Salyzyn from Adaptec.
High Priority Queues have *never* been used in the entire history of the
aac based adapters. Associated with this, aac_insert_entry can be
removed, SavedIrql can be removed & padding variable can be removed.
With the movement of SavedIrql out & replaced with an automatic variable
qflags, the locking can be refined somewhat. The sparse warnings did not
catch the need for byte swapping in the 'dprintk' debugging print
macros, so fixed this up when this code was moved outside of the now
refined locking.

Subject: [PATCH 395/855] [SPARC64]: Simplify Spitfire D-cache page flush.
It tries to batch up the tag loads and comparisons, and
then the stores. And this is just complicated instead
of efficient.
Also, make the symbol of the Cheetah version more grepable.

Subject: [PATCH 396/855] [SPARC64]: Do not do TLB pre-filling any more.
In order to do it correctly on UltraSPARC-III+ and later we'd
need to add some complicated code to set the TAG access extension
register before loading the TLB.
Since this optimization gives questionable gains, it's best to
just remove it for now instead of adding the fix for Ultra-III+

Subject: [PATCH 398/855] [PATCH] useless includes of linux/irq.h in arch/i386
Most of these guys are simply not needed (pulled by other stuff
via asm-i386/hardirq.h). One that is not entirely useless is hilarious -
arch/i386/oprofile/nmi_timer_int.c includes linux/irq.h... as a way to
get linux/errno.h

Subject: [PATCH 402/855] [PATCH] missing dependency on arm O= builds
arm maketools needs include/asm-arm in place in the build tree.
On normal builds it's always there, of course, but on O= it's created
(by generic code) too late - when we get to asm-offset.h.
We used to get away with that by accident - creation of
include/asm-arm/arch symlink creates include/asm-arm and it happened
to go before maketools. However, we did not have such dependency,
so that luck didn't last - now maketools is picked first and we are screwed.
Both the symlink and maketools are prerequisites of the same
target (archprepare). This fix is obvious - make the latter explicitly
depend on the former and be done with that.

Subject: [PATCH 405/855] [TG3]: 5780 PHY fixes
Fix 5780 PHY related problems:
1. MAC_RX_MODE reset must be done before setting up the MAC_MODE
register on 5705_PLUS chips or the chip will stop receiving after
a while. The MAC_RX_MODE reset is needed to prevent intermittently
losing the first receive packet on serdes chips.
2. Skip MAC loopback test on 5780 because of hardware errata. Normal
traffic including PHY loopback is not affected by the errata.
3. PHY loopback fails intermittently on 5708S and this is fixed by
putting the PHY in loopback mode first before programming the MAC
mode register. A MAC_RX_MODE reset is also added.
4. Return -EINVAL in tg3_nway_reset() if device is in TBI mode. Allow
nway_reset if 5780S is in parallel detect mode.
5. Add missing PHY IDs in KNOWN_PHY_ID() macro.

Date: Tue, 27 Sep 2005 12:13:10 -0700
Subject: [PATCH 406/855] [TG3]: misc. fixes
Fix interrupt test handler by adding check for IRQ assertion in
PCI_STATE register in addition to the status block updated bit.
Add test for valid ethernet address in tg3_set_mac_addr().
Add tg3_bus_string() to setup the PCI bus speed/width string for all
PCI/PCIX/PCI Express devices. This is used to print the bus type
during init_one().

Subject: [PATCH 412/855] [NET]: Reorder some hot fields of struct net_device
Place them on separate cache lines in SMP to lower memory bouncing
between multiple CPU accessing the device.
- One part is mostly used on receive path (including
eth_type_trans()) (poll_list, poll, quota, weight, last_rx,
dev_addr, broadcast)
- One part is mostly used on queue transmit path (qdisc)
(queue_lock, qdisc, qdisc_sleeping, qdisc_list, tx_queue_len)
- One part is mostly used on xmit path (device)
(xmit_lock, xmit_lock_owner, priv, hard_start_xmit, trans_start)
'features' is placed outside of these hot points, in a location that
may be shared by all cpus (because mostly read)
name_hlist is moved close to name[IFNAMSIZ] to speedup __dev_get_by_name()

Subject: [PATCH 413/855] [NET]: Fix module reference counts for loadable
protocol modules
I have been experimenting with loadable protocol modules, and ran into
several issues with module reference counting.
The first issue was that __module_get failed at the BUG_ON check at
the top of the routine (checking that my module reference count was
not zero) when I created the first socket. When sk_alloc() is called,
my module reference count was still 0. When I looked at why sctp
didn't have this problem, I discovered that sctp creates a control
socket during module init (when the module ref count is not 0), which
keeps the reference count non-zero. This section has been updated to
address the point Stephen raised about checking the return value of
try_module_get().
The next problem arose when my socket init routine returned an error.
This resulted in my module reference count being decremented below 0.
My socket ops->release routine was also being called. The issue here
is that sock_release() calls the ops->release routine and decrements
the ref count if sock->ops is not NULL. Since the socket probably
didn't get correctly initialized, this should not be done, so we will
set sock->ops to NULL because we will not call try_module_get().
While searching for another bug, I also noticed that sys_accept() has
a possibility of doing a module_put() when it did not do an
__module_get so I re-ordered the call to security_socket_accept().

+ *
+ * This driver uses the sungem driver (c) David Miller
+ * (davem@redhat.com) as its basis.
+ *
+ * The cassini chip has a number of features that distinguish it from
+ * the gem chip:
+ * 4 transmit descriptor rings that are used for either QoS (VLAN) or
+ * load balancing (non-VLAN mode)
+ * batching of multiple packets
+ * multiple CPU dispatching
+ * page-based RX descriptor engine with separate completion rings
+ * Gigabit support (GMII and PCS interface)
+ * MIF link up/down detection works
+ *
+ * RX is handled by page sized buffers that are attached as fragments to
+ * the skb. here's what's done:
+ * -- driver allocates pages at a time and keeps reference counts
+ * on them.
+ * -- the upper protocol layers assume that the header is in the skb
+ * itself. as a result, cassini will copy a small amount (64 bytes)
+ * to make them happy.
+ * -- driver appends the rest of the data pages as frags to skbuffs
+ * and increments the reference count
+ * -- on page reclamation, the driver swaps the page with a spare page.
+ * if that page is still in use, it frees its reference to that page,
+ * and allocates a new page for use. otherwise, it just recycles the
+ * the page.
+ *
+ * NOTE: cassini can parse the header. however, it's not worth it
+ * as long as the network stack requires a header copy.
+ *
+ * TX has 4 queues. currently these queues are used in a round-robin
+ * fashion for load balancing. They can also be used for QoS. for that
+ * to work, however, QoS information needs to be exposed down to the driver
+ * level so that subqueues get targetted to particular transmit rings.
+ * alternatively, the queues can be configured via use of the all-purpose
+ * ioctl.
+ *
+ * RX DATA: the rx completion ring has all the info, but the rx desc
+ * ring has all of the data. RX can conceivably come in under multiple
+ * interrupts, but the INT# assignment needs to be set up properly by
+ * the BIOS and conveyed to the driver. PCI BIOSes don't know how to do
+ * that. also, the two descriptor rings are designed to distinguish between
+ * encrypted and non-encrypted packets, but we use them for buffering
+ * instead.
+ *
+ * by default, the selective clear mask is set up to process rx packets.

Subject: [PATCH 421/855] [APPLETALK]: Fix broadcast bug.
From: Oliver Dawid <oliver@helios.de>
we found a bug in net/appletalk/ddp.c concerning broadcast packets. In
kernel 2.4 it was working fine. The bug first occured 4 years ago when
switching to new SNAP layer handling. This bug can be splitted up into a
sending(1) and reception(2) problem:
Sending(1)
In kernel 2.4 broadcast packets were sent to a matching ethernet device
and atalk_rcv() was called to receive it as "loopback" (so loopback
packets were shortcutted and handled in DDP layer).
When switching to the new SNAP structure, this shortcut was removed and
the loopback packet was send to SNAP layer. The author forgot to replace
the remote device pointer by the loopback device pointer before sending
the packet to SNAP layer (by calling ddp_dl->request() ) therfor the
packet was not sent back by underlying layers to ddp's atalk_rcv().
Reception(2)
In atalk_rcv() a packet received by this loopback mechanism contains now
the (rigth) loopback device pointer (in Kernel 2.4 it was the (wrong)
remote ethernet device pointer) and therefor no matching socket will be
found to deliver this packet to. Because a broadcast packet should be
send to the first matching socket (as it is done in many other protocols
(?)), we removed the network comparison in broadcast case.
Below you will find a patch to correct this bug. Its diffed to kernel
2.6.14-rc1

Subject: [PATCH 424/855] [PATCH] mm: move_pte to remap ZERO_PAGE
Move the ZERO_PAGE remapping complexity to the move_pte macro in
asm-generic, have it conditionally depend on
__HAVE_ARCH_MULTIPLE_ZERO_PAGE, which gets defined for MIPS.
For architectures without __HAVE_ARCH_MULTIPLE_ZERO_PAGE, move_pte becomes
a noop.
From: Hugh Dickins <hugh@veritas.com>
Fix nasty little bug we've missed in Nick's mremap move ZERO_PAGE patch.
The "pte" at that point may be a swap entry or a pte_file entry: we must
check pte_present before perhaps corrupting such an entry.
Patch below against 2.6.14-rc2-mm1, but the same bug is in 2.6.14-rc2's
mm/mremap.c, and more dangerous there since it's affecting all arches: I
think the safest course is to send Nick's patch and Yoichi's build fix and
this fix (build tested) on to Linus - so only MIPS can be affected.

Subject: [PATCH 429/855] [PATCH] v9fs: fix races in fid allocation
Fid management cleanup. The patch attempts to fix the races in dentry's
fid management.
Dentries don't keep the opened fids anymore, they are moved to the file
structs. Ideally there should be no more than one fid with fidcreate equal
to zero in the dentry's list of fids.
v9fs_fid_create initializes the important fields (fid, fidcreated) before
v9fs_fid is added to the list. v9fs_fid_lookup returns only fids that are
not created by v9fs_create. v9fs_fid_get_created returns the fid created
by the same process by v9fs_create (if any) and removes it from dentry's
list

Subject: [PATCH 432/855] [PATCH] swsusp: remove wrong code from data_free
The following patch removes some wrong code from the data_free() function
in swsusp.
This function could only be called if there's an error while writing the
suspend image to swap, so it is not triggered easily. However, if
triggered, it would probably corrupt some memory.

have synced TSCs
This should resolve the issue seen in bugme bug #5105, where it is assumed
that dualcore x86_64 systems have synced TSCs. This is not the case, and
alternate timesources should be used instead.
For more details, see:
http://bugzilla.kernel.org/show_bug.cgi?id=5105
Andi's earlier concerns that the TSCs should be synced on dualcore systems
have been resolved by confirmation from AMD folks that they can be
unsynced.

Subject: [PATCH 444/855] [PATCH] device-mapper: Fix queue_if_no_path
initialisation
When creating a multipath device, if the queue_if_no_path parameter is
specified it gets ignored.
While the queue_if_no_path variable is correctly set to 1, the
saved_queue_if_no_path gets set to 0. When the device is subsequently made
live (resumed), the saved value (0) always overwrites the live value (1) so
the option *always* gets turned off.
The fix adds a parameter to the queue_if_no_path() function to indicate
whether the previous value should be preserved or not - if not, as when the
device is being set up, the saved value is set to the new value (1).

Subject: [PATCH 446/855] [PATCH] kmalloc_node IRQ safety fix
In kmalloc_node we are checking if the allocation is for the same node when
interrupts are "on". This may lead to an allocation on another node than
intended.
This patch just shifts the check for the current node in __cache_alloc_node
when interrupts are disabled.

Subject: [PATCH 448/855] [PATCH] Keys: Add possessor permissions to keys [try
#3]
The attached patch adds extra permission grants to keys for the possessor of a
key in addition to the owner, group and other permissions bits. This makes
SUID binaries easier to support without going as far as labelling keys and key
targets using the LSM facilities.
This patch adds a second "pointer type" to key structures (struct key_ref *)
that can have the bottom bit of the address set to indicate the possession of
a key. This is propagated through searches from the keyring to the discovered
key. It has been made a separate type so that the compiler can spot attempts
to dereference a potentially incorrect pointer.
The "possession" attribute can't be attached to a key structure directly as
it's not an intrinsic property of a key.
Pointers to keys have been replaced with struct key_ref *'s wherever
possession information needs to be passed through.
This does assume that the bottom bit of the pointer will always be zero on
return from kmem_cache_alloc().
The key reference type has been made into a typedef so that at least it can be
located in the sources, even though it's basically a pointer to an undefined
type. I've also renamed the accessor functions to be more useful, and all
reference variables should now end in "_ref".

Rename IPoIB driver's path_lookup() to ipoib_path_lookup() to avoid a
clashes with the kernel global path_lookup(). We don't hit this with
the current kernel source, but some external patches seem to trigger
this, and it's cleaner to avoid clashing with global names anyway.

From 5fd29752f09cabff582f65c0ce35518db4c64937 Mon Sep 17 00:00:00 2001
From: "David S. Miller" <davem@sunset.davemloft.net>
Date: Wed, 28 Sep 2005 20:41:45 -0700
Subject: [PATCH 458/855] [SPARC64]: Fix fault handling in unaligned trap
handler.
We were not calling kernel_mna_trap_fault() correctly.
Instead of being fancy, just return 0 vs. -EFAULT from
the assembler stubs, and handle that return value as
appropriate.
Create an "__retl_efault" stub for assembler exception
table entries and use it where possible.
Signed-off-by: David S. Miller <davem@davemloft.net>

Date: Wed, 28 Sep 2005 21:06:47 -0700
Subject: [PATCH 459/855] [SPARC64]: Simplify user fault fixup handling.
Instead of doing byte-at-a-time user accesses to figure
out where the fault occurred, read the saved fault_address
from the current thread structure.
For the sake of defensive programming, if the fault_address
does not fall into the user buffer range, simply assume the
whole area faulted. This will cause the fixup for
copy_from_user() to clear the entire kernel side buffer.

Subject: [PATCH 467/855] [ARM] Don't include asm/arch/hardware.h directly
Since asm/hardware.h's only reason for existing is to include
asm/arch/hardware.h, it's completely pointless to include both.

Subject: [PATCH 468/855] [ARM] Don't include mach-types.h unnecessarily
It's pointless to include mach-types.h if you're not going to use
anything from it. These references were removed as a result of:
grep -lr 'asm/mach-types\.h' . | xargs grep -L 'machine_is_\|MACH_TYPE_\|MACHINE_START\|machine_type'

Subject: [PATCH 471/855] [PATCH] uml makefiles sanitized
UML makefiles sanitized:
- number of generated headers reduced to 2 (from user-offsets.c and
kernel-offsets.c resp.). The rest is made constant and simply
includes those two.
- mk_... helpers are gone now that we don't need to generate these
headers
- arch/um/include2 removed since everything under arch/um/include/sysdep
is constant now and symlink can point straight to source tree.
- dependencies seriously simplified.

Subject: [PATCH 472/855] [PATCH] proc_mkdir() should be used to create procfs
directories
A bunch of create_proc_dir_entry() calls creating directories had crept
in since the last sweep; converted to proc_mkdir().

Subject: [PATCH 480/855] [PATCH] ppc32 ld.script fix for building on ppc64
In arch/ppc/boot/ld.script we need OUTPUT_ARCH(powerpc:common) for the
same reasons why we need it in vmlinux.lds.S; when we build on ppc64
box, we need to be explicit about the target.
See http://linus.bkbits.net:8080/linux-2.5/cset@1.1784.8.10 for the
corresponding fix in vmlinux.lds.S.

interaction
do_signal_stop:
for_each_thread(t) {
if (t->state < TASK_STOPPED)

}
However, TASK_NONINTERACTIVE > TASK_STOPPED, so this loop will not
count TASK_INTERRUPTIBLE | TASK_NONINTERACTIVE threads.
See also wait_task_stopped(), which checks ->state > TASK_STOPPED.

[ We really probably should always use the appropriate bitmasks to test
task states, not do it like this. Using something like
#define TASK_RUNNABLE (TASK_RUNNING | TASK_INTERRUPTIBLE | \
TASK_UNINTERRUPTIBLE | TASK_NONINTERACTIVE)
and then doing "if (task->state & TASK_RUNNABLE)" or similar. But the
ordering of the task states is historical, and keeping the ordering
does make sense regardless. ]

Any tests using < TASK_STOPPED or the like are left over from the time
when the TASK_ZOMBIE and TASK_DEAD bits were in the same word, and it
served to check for "stopped or dead". I think this one in
do_signal_stop is the only such case. It has been buggy ever since
exit_state was separated, and isn't testing the exit_state value.

Subject: [PATCH 493/855] [PATCH] x86_64: Fix mce_log
The attempt to fixup the lockless mce log buffer introduced an infinite loop
when trying to find a free entry.
And:
Using rcu_dereference() to load mcelog.next doesn't seem to be sufficient
enough to ensure that mcelog.next is loaded each time around the loop in
mce_log(). Instead, use an explicit rmb() to ensure that the compiler gets it
right.
AK: turned the smp_wmbs into true wmbs to make sure they are not
reordered by the compiler on UP.

and return without releasing it. This fixes it. With that patch, the
driver is rock solid with my experimental thermal control (which bangs
it pretty hard) racing with real time clock and cpufreq handling.

Subject: [PATCH 496/855] [ARM] 2941/1: Fix running legacy binaries from a
soft-float root filesystem with CONFIG_IWMMXT.
Patch from Daniel Jacobowitz
Thread flags are inherited on fork(). In order for a binary which has
the iWMMXt coprocessor enabled to run a binary which needs the FPA
emulation, we need to explicitly clear TIF_USING_IWMMXT if we are not
going to set it.

Subject: [PATCH 497/855] [TCP]: Revert
6b251858d377196b8cea20e65cae60f584a42735
But retain the comment fix.
Alexey Kuznetsov has explained the situation as follows:
--------------------
I think the fix is incorrect. Look, the RFC function init_cwnd(mss) is
not continuous: f.e. for mss=1095 it needs initial window 1095*4, but
for mss=1096 it is 1096*3. We do not know exactly what mss sender used
for calculations. If we advertised 1096 (and calculate initial window
3*1096), the sender could limit it to some value < 1096 and then it
will need window his_mss*4 > 3*1096 to send initial burst.
See?
So, the honest function for inital rcv_wnd derived from
tcp_init_cwnd() is:
init_rcv_wnd(mss)=
min { init_cwnd(mss1)*mss1 for mss1 <= mss }
It is something sort of:
if (mss < 1096)
return mss*4;
if (mss < 1096*2)
return 1096*4;
return mss*2;
(I just scrablled a graph of piece of paper, it is difficult to see or
to explain without this)
I selected it differently giving more window than it is strictly
required. Initial receive window must be large enough to allow sender
following to the rfc (or just setting initial cwnd to 2) to send
initial burst. But besides that it is arbitrary, so I decided to give
slack space of one segment.
Actually, the logic was:
If mss is low/normal (<=ethernet), set window to receive more than
initial burst allowed by rfc under the worst conditions
i.e. mss*4. This gives slack space of 1 segment for ethernet frames.
For msses slighlty more than ethernet frame, take 3. Try to give slack
space of 1 frame again.
If mss is huge, force 2*mss. No slack space.
Value 1460*3 is really confusing. Minimal one is 1096*2, but besides
that it is an arbitrary value. It was meant to be ~4096. 1460*3 is
just the magic number from RFC, 1460*3 = 1095*4 is the magic :-), so
that I guess hands typed this themselves.

Subject: [PATCH 498/855] [TCP]: Don't over-clamp window in tcp_clamp_window()
From: Alexey Kuznetsov <kuznet@ms2.inr.ac.ru>
Handle better the case where the sender sends full sized
frames initially, then moves to a mode where it trickles
out small amounts of data at a time.
This known problem is even mentioned in the comments
above tcp_grow_window() in tcp_input.c, specifically:
...
* The scheme does not work when sender sends good segments opening
* window and then starts to feed us spagetti. But it should work
* in common situations. Otherwise, we have to rely on queue collapsing.
...
When the sender gives full sized frames, the "struct sk_buff" overhead
from each packet is small. So we'll advertize a larger window.
If the sender moves to a mode where small segments are sent, this
ratio becomes tilted to the other extreme and we start overrunning
the socket buffer space.
tcp_clamp_window() tries to address this, but it's clamping of
tp->window_clamp is a wee bit too aggressive for this particular case.
Fix confirmed by Ion Badulescu.

Subject: [PATCH 503/855] [SPARC64]: Fix several bugs in flush_ptrace_access().
1) Use cpudata cache line sizes, not magic constants.
2) Align start address in cheetah case so we do not get
unaligned address traps. (pgrep was good at triggering
this, via /proc/${pid}/cmdline accesses)

Subject: [PATCH 504/855] [RADEON]: Fix unaligned I/O port access during probe.
The driver does a readl() on DEVICE_ID which is 2-byte aligned and
2-bytes in size. It's doing this read just to flush write buffers.
Create IN16() and OUT16() macros, and use the former to do this I/O
load.

Date: Fri, 30 Sep 2005 16:07:04 +0100
Subject: [PATCH 507/855] [ARM] 2939/1: Fix compilation error in
arch/arm/mm/flush.c
Patch from Catalin Marinas
When CONFIG_CPU_CACHE_VIPT is defined, the flush_pfn_alias() function is
implicitely declared and it later conflicts with its actual definition.
This patch moves the function definition to the beginning of the file.

It might be version-dependent, but at least 4.0.1 refuses to accept

Subject: [PATCH 521/855] [PATCH] i386: include linux/irq.h rather than
asm/hw_irq.h
I need the following patch to compile -git8 here, otherwise these
files fail to compile (asm/hw_irq.h needs definitions from
linux/irq.h and that file provides the required include ordering).
I did not do a full audit, though there looks to be many other
places that should get the same treatment, if this is the right
way to do it.

Subject: [PATCH 522/855] [PATCH] SELinux - fix SCTP socket bug and general IP
protocol handling
The following patch updates the way SELinux classifies and handles IP
based protocols.
Currently, IP sockets are classified by SELinux as being either TCP, UDP
or 'Raw', the latter being a default for IP socket that is not TCP or UDP.
The classification code is out of date and uses only the socket type
parameter to socket(2) to determine the class of IP socket. So, any
socket created with SOCK_STREAM will be classified by SELinux as TCP, and
SOCK_DGRAM as UDP. Also, other socket types such as SOCK_SEQPACKET and
SOCK_DCCP are currently ignored by SELinux, which classifies them as
generic sockets, which means they don't even get basic IP level checking.
This patch changes the SELinux IP socket classification logic, so that
only an IPPROTO_IP protocol value passed to socket(2) classify the socket
as TCP or UDP. The patch also drops the check for SOCK_RAW and converts
it into a default, so that socket types like SOCK_DCCP and SOCK_SEQPACKET
are classified as SECCLASS_RAWIP_SOCKET (instead of generic sockets).
Note that protocol-specific support for SCTP, DCCP etc. is not addressed
here, we're just getting these protocols checked at the IP layer.
This fixes a reported problem where SCTP sockets were being recognized as
generic SELinux sockets yet still being passed in one case to an IP level
check, which then fails for generic sockets.
It will also fix bugs where any SOCK_STREAM socket is classified as TCP or
any SOCK_DGRAM socket is classified as UDP.
This patch also unifies the way IP sockets classes are determined in
selinux_socket_bind(), so we use the already calculated value instead of
trying to recalculate it.

Subject: [PATCH 524/855] [PATCH] aio: lock around kiocbTryKick()
Only one of the run or kick path is supposed to put an iocb on the run
list. If both of them do it than one of them can end up referencing a
freed iocb. The kick patch could set the Kicked bit before acquiring the
ctx_lock and putting the iocb on the run list. The run path, while holding
the ctx_lock, could see this partial kick and mistake it for a kick that
was deferred while it was doing work with the run_list NULLed out. It
would then race with the kick thread to add the iocb to the run list.
This patch moves the kick setting under the ctx_lock so that only one of
the kick or run path queues the iocb on the run list, as intended.

Subject: [PATCH 525/855] [PATCH] aio: remove unlocked task_list test and
resulting race
Only one of the run or kick path is supposed to put an iocb on the run
list. If both of them do it than one of them can end up referencing a
freed iocb. The kick path could delete the task_list item from the wait
queue before getting the ctx_lock and putting the iocb on the run list.
The run path was testing the task_list item outside the lock so that it
could catch ki_retry methods that return -EIOCBRETRY *without* putting the
iocb on a wait queue and promising to call kick_iocb. This unlocked check
could then race with the kick path to cause both to try and put the iocb on
the run list.
The patch stops the run path from testing task_list by requring that any
ki_retry that returns -EIOCBRETRY *must* guarantee that kick_iocb() will be
called in the future. aio_p{read,write}, the only in-tree -EIOCBRETRY
users, are updated.

Subject: [PATCH 529/855] [PATCH] uml: fix page faults in SKAS3 mode.
I hadn't been running a SKAS3 host when testing the "uml: fix hang in TT mode
on fault" patch (commit 546fe1cbf91d4d62e3849517c31a2327c992e5c5), and I
didn't think enough to the missing trap_no in SKAS3 mode.
In fact, the resulting kernel doesn't work at all in SKAS3 mode.

Revert commit 12ebcd73e40e09f0dfddf89e465cc0541e0ff8b1, i.e. [PATCH] uml: run
mconsole "sysrq" in process context on request from Jeff Dike.
a) sysrq may be run when the scheduler is non-functioning
b) the warning I wanted to fix actually came from the fault handler run in
atomic context. But I fixed that not to take the semaphore in a separate
patch.
c) the fault handler is run because of a fault, and that fault was
unaffected by this patch.

Subject: [PATCH 532/855] [PATCH] uml: remove empty hostfs_truncate method
Calling truncate() on hostfs spits a kernel warning "Something isn't
implemented here", but it still works fine.
Indeed, hostfs i_op->truncate doesn't do anything. But hostfs_setattr() ->
set_attr() correctly detects ATTR_SIZE and calls truncate() on the host. So
we should be safe (using ftruncate() may be better, in case the file is
unlinked on the host, but we aren't sure to have the file open for writing,
and reopening it would cause the same races; plus nobody should expect UML to
be so careful).
So, the warning is wrong, because the current implementation is working. Al,
am I correct, and can the warning be therefore dropped?

Subject: [PATCH 534/855] [PATCH] ioc4_serial: Remove bogus error message
This change removes a bogus error message from the IOC4 serial driver
interrupt handler.
This error message is bogus for two reasons. First, it can never occur
given that current code takes care to initialize IOC4 in such a way that
these "unknown" interrupts could never occur. Second, this code fails to
take into account that other drivers can share the IOC4 interrupt mechanism
through SA_SHIRQ, and thus this driver is not in-fact "all-knowing".
Finally, this error message triggers every time some "unknown" interrupt
occurs -- it's not rate limited or repetition limited in any way, thereby
effectively denying use of the console device. Given its bogosity in the
first place, it's best to just get rid of it entirely.

Subject: [PATCH 536/855] [PATCH] sbp2: fix deadlocks and delays on device
removal/rmmod
Fixes for deadlocks of the ieee1394 and scsi subsystems and long delays in
futile error recovery attempts when SBP-2 devices are removed or drivers are
unloaded.
- Complete commands quickly with DID_NO_CONNECT if the 1394 node is gone or if
the 1394 low-level driver was unloaded.
- Skip unnecessary work in the eh_abort_handler and eh_device_reset_handler if
the node or 1394 low-level driver is gone.
- Let scsi's high-level shut down gracefully when sbp2 is being unloaded or
detached from the 1394 unit. A call to scsi_remove_device is added for this
purpose, which requires us to store a scsi_device pointer.
- scsi_device pointer is obtained from slave_alloc hook and cleared by
slave_destroy. This avoids usage of the pointer after the scsi device was
deleted e.g. by the user via scsi_mod's sysfs interface.

Subject: [PATCH 537/855] [PATCH] sbp2: default to serialize_io=1
Set serialize_io=1 by default. This is safer and required by seemingly more
and more hardware. It causes little or no performance loss for S400 devices.
Performance of S800 1394b devices may drop by 25...30%. Therefore make the
parameter's description and dmesg message clearer about performance impact.
Update description of the max_speed parameter too. IEEE1394_SPEED_MAX is
currently S800.

Units were not detected if the local IRM performed a bus reset. ("The root

often seen with iPods and other SBP-2 devices). Rearrange the order of IRM
duties and node scanning. TODO: Audit the ROM caching and parsing code for
underlying issues.

Subject: [PATCH 547/855] [PATCH] utilization of kprobe_mutex is incorrect on
x86_64
The up()/down() orders are incorrect in arch/x86_64/kprobes.c file.
kprobe_mutext is used to protect the free kprobe instruction slot list.
arch_prepare_kprobe applies for a slot from the free list, and
arch_remove_kprobe returns a slot to the free list. The incorrect up()/down()
orders to operate on kprobe_mutex fail to protect the free list. If 2 threads
try to get/return kprobe instruction slot at the same time, the free slot list
might be broken, or a free slot might be applied by 2 threads.

Subject: [PATCH 548/855] [PATCH] x86_64: fix the BP node_to_cpumask
Fix the BP node_to_cpumask. 2.6.14-rc* broke the boot cpu bit as the
cpu_to_node(0) is now not setup early enough for numa_init_array.
cpu_to_node[] is setup much later at srat_detect_node on acpi srat based
em64t machines. This seems like a problem on amd machines too, Tested on
em64t though. /sys/devices/system/node/node0/cpumap shows up sanely after
this patch.

Subject: [PATCH 549/855] [PATCH] x86_64 early numa init fix
The tests Alok carried out on Petr's box confirmed that cpu_to_node[BP] is
not setup early enough by numa_init_array due to the x86_64 changes in
2.6.14-rc*, and unfortunately set wrongly by the work around code in
numa_init_array(). cpu_to_node[0] gets set with 1 early and later gets set
properly to 0 during identify_cpu() when all cpus are brought up, but
confusing the numa slab in the process.
Here is a quick fix for this. The right fix obviously is to have
cpu_to_node[bsp] setup early for numa_init_array(). The following patch
will fix the problem now, and the code can stay on even when
cpu_to_node{BP] gets fixed early correctly.
Thanks to Petr for access to his box.

The old 550Mhz titanium powerbook can switch to a lower frequency
(500Mhz). A user has been repeately reporting overtemp conditions on his
machine at high speed so this simple patch adds support to PowerMac
cpufreq for this machine. The difference in frequency isn't big but seem
enough to fix that user's problems. The patch has been around for some
time now and doesn't seem to cause any problem, so I suppose it could go

Subject: [PATCH 558/855] Fix inequality comparison against "task->state"
We should always use bitmask ops, rather than depend on some ordering of
the different states. With the TASK_NONINTERACTIVE flag, the inequality
doesn't really work.
Oleg Nesterov argues (likely correctly) that this test is unnecessary in
the first place. However, the minimal fix for now is to at least make
it work in the presense of TASK_NONINTERACTIVE. Waiting for consensus
from Roland & co on potential bigger cleanups.

Subject: [PATCH 561/855] [PATCH] pmac/radeonfb: Add suspend support for M11
chip in new iBook 12"
This adds suspend support for the Radeon M11 chip in 12" iBooks
manufactured after July 2005. I don't know if the new 14" iBooks also
have that chip, so they might also be supported.
The chip identifies itself as "RV350 NV" (pci id 0x4e56), revision 0x80.
Apple calls it "Snowy", xfree86 names it "ATI FireGL Mobility T2 (M11)
NV (AGP)". So, we seem to be lucky here: The suspend-code for the M10
(which also is a "RV350 NV") works flawless for that chip.

Subject: [PATCH 565/855] [SCSI] fix potential panic with proc on module
removal
There's a problem in our host release in that it calls
scsi_proc_hostdir_rm(). However, if you hold a reference to the host as
you remove the module, the host template (which proc uses) will be freed
and the system will panic when the host device is finally released.
Fix this by moving scsi_proc_hostdir_rm() to where it should be: in
scsi_remove_host().

In these drivers, scsi_remove_host() is called too late, at the point
it is called, the driver has already shut down too far to accept any
I/O that the shutdown might generate. Any generated I/O actually
triggers a panic.
Fix this by calling scsi_remove_host() as early as possible and not
calling scsi_host_put() until just before we kfree the ahc_softc.

Subject: [PATCH 567/855] [PATCH] alpha: fix kernel alignment traps
Pass in the pointer to the on-stack registers rather than using them
directly as the arguments.
Ivan noticed that I missed a spot when purging the registers as first
stack parameter idiom.

+The canonical patch subject line is:
+
+ Subject: [PATCH 001/123] [<area>:] <explanation>
+
+The canonical patch message body contains the following:
+
+ - A "from" line specifying the patch author.
+
+ - An empty line.
+
+ - The body of the explanation, which will be copied to the
+ permanent changelog to describe this patch.
+
+ - The "Signed-off-by:" lines, described above, which will
+ also go in the changelog.
+
+ - A marker line containing simply "---".
+
+ - Any additional comments not suitable for the changelog.
+
+ - The actual patch (diff output).
+
+The Subject line format makes it very easy to sort the emails
+alphabetically by subject line - pretty much any email reader will
+support that - since because the sequence number is zero-padded,
+the numerical and alphabetic sort is the same.
+
+See further details on how to phrase the "<explanation>" in the
+"Subject:" line in Andrew Morton's "The perfect patch", referenced
+below.
+
+The "from" line must be the very first line in the message body,
+and has the form:
+
+ From: Original Author <author@example.com>
+
+The "from" line specifies who will be credited as the author of the
+patch in the permanent changelog. If the "from" line is missing,
+then the "From:" line from the email header will be used to determine
+the patch author in the changelog.
+
+The explanation body will be committed to the permanent source
+changelog, so should make sense to a competent reader who has long
+since forgotten the immediate details of the discussion that might
+have led to this patch.
+
+The "---" marker line serves the essential purpose of marking for patch
+handling tools where the changelog message ends.
+
+One good use for the additional comments after the "---" marker is for
+a diffstat, to show what files have changed, and the number of inserted
+and deleted lines per file. A diffstat is especially useful on bigger
+patches. Other comments relevant only to the moment or the maintainer,
+not suitable for the permanent changelog, should also go here.

Subject: [PATCH 570/855] [SCSI] Legacy MegaRAID: Fix READ CAPACITY
Some Legacy megaraid cards can't actually cope with the scatter/gather
version of the READ CAPACITY command (which is what we now send them
since altering all SCSI internal I/O to go via the block layer). Fix
this (and a few other broken megaraid driver assumptions) by sending
the non-sg version of the command if the sg list only has a single
element.

Subject: [PATCH 572/855] [PATCH] x86_64: Fix numa node topology detection for
srat based x86_64 boxes
2.6.14-rc2 does not assign cpus to proper nodeids on our em64t numa boxen.
Our boxes use acpi srat for parsing the numa information.
srat_detect_node() used phys_proc_id[] to get to the cpu's local apic id,
but phys_proc_id[] represents the cpu<->initial_apic_id mapping. The
following patch fixes this problem. Now apicid_to_node[] is properly
indexed with the local apic id.

Subject: [PATCH 573/855] [NET]: Fix packet timestamping.
I've found the problem in general. It affects any 64-bit
architecture. The problem occurs when you change the system time.
Suppose that when you boot your system clock is forward by a day.
This gets recorded down in skb_tv_base. You then wind the clock back
by a day. From that point onwards the offset will be negative which
essentially overflows the 32-bit variables they're stored in.
In fact, why don't we just store the real time stamp in those 32-bit
variables? After all, we're not going to overflow for quite a while
yet.
When we do overflow, we'll need a better solution of course.

Subject: [PATCH 575/855] [TG3]: Refine AMD K8 write-reorder chipset test.
Test for VIA K8T800 north bridge instead of AMD K8 HyperTransport
bridge based on new information from Andi Kleen. The AMD
HyperTransport interface is not responsible for PCI transactions
and so the re-ordering is more likely done by the VIA north bridge.
This code is subject to change if we get more information from AMD
or VIA.
PCI Express devices are excluded from doing the read flush since all
chipsets in the write_reorder list are PCI chipsets.

Subject: [PATCH 576/855] [INET]: speedup inet (tcp/dccp) lookups
Arnaldo and I agreed it could be applied now, because I have other
pending patches depending on this one (Thank you Arnaldo)
(The other important patch moves skc_refcnt in a separate cache line,
so that the SMP/NUMA performance doesnt suffer from cache line ping pongs)
1) First some performance data :
--------------------------------
tcp_v4_rcv() wastes a *lot* of time in __inet_lookup_established()
The most time critical code is :
sk_for_each(sk, node, &head->chain) {
if (INET_MATCH(sk, acookie, saddr, daddr, ports, dif))
goto hit; /* You sunk my battleship! */
}
The sk_for_each() does use prefetch() hints but only the begining of
"struct sock" is prefetched.
As INET_MATCH first comparison uses inet_sk(__sk)->daddr, wich is far
away from the begining of "struct sock", it has to bring into CPU
cache cold cache line. Each iteration has to use at least 2 cache
lines.
This can be problematic if some chains are very long.
2) The goal
-----------
The idea I had is to change things so that INET_MATCH() may return
FALSE in 99% of cases only using the data already in the CPU cache,
using one cache line per iteration.
3) Description of the patch
---------------------------
Adds a new 'unsigned int skc_hash' field in 'struct sock_common',
filling a 32 bits hole on 64 bits platform.
struct sock_common {
unsigned short skc_family;
volatile unsigned char skc_state;
unsigned char skc_reuse;
int skc_bound_dev_if;
struct hlist_node skc_node;
struct hlist_node skc_bind_node;
atomic_t skc_refcnt;
+ unsigned int skc_hash;
struct proto *skc_prot;
};
Store in this 32 bits field the full hash, not masked by (ehash_size -
1) Using this full hash as the first comparison done in INET_MATCH
permits us immediatly skip the element without touching a second cache
line in case of a miss.
Suppress the sk_hashent/tw_hashent fields since skc_hash (aliased to
sk_hash and tw_hash) already contains the slot number if we mask with
(ehash_size - 1)
File include/net/inet_hashtables.h
64 bits platforms :
#define INET_MATCH(__sk, __hash, __cookie, __saddr, __daddr, __ports, __dif)\
(((__sk)->sk_hash == (__hash))
((*((__u64 *)&(inet_sk(__sk)->daddr)))== (__cookie)) && \
((*((__u32 *)&(inet_sk(__sk)->dport))) == (__ports)) && \
(!((__sk)->sk_bound_dev_if) || ((__sk)->sk_bound_dev_if == (__dif))))
32bits platforms:
#define TCP_IPV4_MATCH(__sk, __hash, __cookie, __saddr, __daddr, __ports, __dif)\
(((__sk)->sk_hash == (__hash)) && \
(inet_sk(__sk)->daddr == (__saddr)) && \
(inet_sk(__sk)->rcv_saddr == (__daddr)) && \
(!((__sk)->sk_bound_dev_if) || ((__sk)->sk_bound_dev_if == (__dif))))
- Adds a prefetch(head->chain.first) in
__inet_lookup_established()/__tcp_v4_check_established() and
__inet6_lookup_established()/__tcp_v6_check_established() and
__dccp_v4_check_established() to bring into cache the first element of the
list, before the {read|write}_lock(&head->lock);

Subject: [PATCH 577/855] [NET]: Fix "sysctl_net.c:36: error: 'core_table'
undeclared here"
During the build for ARM machine type "fortunet", this error occurred:
CC net/sysctl_net.o
net/sysctl_net.c:36: error: 'core_table' undeclared here (not in a function)
It appears that the following configuration settings cause this error
due to a missing include:
CONFIG_SYSCTL=y
CONFIG_NET=y
# CONFIG_INET is not set
core_table appears to be declared in net/sock.h. if CONFIG_INET were
defined, net/sock.h would have been included via:
sysctl_net.c -> net/ip.h -> linux/ip.h -> net/sock.h
so include it directly.

The breakage is caused by the change to use the CB area for flagging
whether a packet has been queued due to proxy_delay. This area gets
cleared every time arp_rcv gets called. Unfortunately packets delayed
due to proxy_delay also go through arp_rcv when they are reprocessed.
In fact, I can't think of a reason why delayed proxy packets should go
through netfilter again at all. So the easiest solution is to bypass
that and go straight to arp_process.
This is essentially what would've happened before netfilter support
was added to ARP.

Subject: [PATCH 581/855] [IPV4]: Replace __in_dev_get with
__in_dev_get_rcu/rtnl
The following patch renames __in_dev_get() to __in_dev_get_rtnl() and
introduces __in_dev_get_rcu() to cover the second case.
1) RCU with refcnt should use in_dev_get().
2) RCU without refcnt should use __in_dev_get_rcu().
3) All others must hold RTNL and use __in_dev_get_rtnl().
There is one exception in net/ipv4/route.c which is in fact a pre-existing
race condition. I've marked it as such so that we remember to fix it.
This patch is based on suggestions and prior work by Suzanne Wood and
Paul McKenney.

From: Peter Tiedemann <ptiedem@de.ibm.com>
From: Frank Pavlic <pavlic@de.ibm.com>
minor qeth fixes:
- free old skb in qeth_realloc_headroom after duplicating skb
- disable IPV6 support for Hipersockets devices
- call ccw_device_set_offline on every channel regardless
of the return value of the prior ccw_device_set_offline calls
- allocate qdio structures in DMA-area
- schedule recovery of appropriate card
when cable has been inserted again.
- add missing initialization of card->lock
- write sequence number in skb->cb for SNA protocol which
requires strictly serialized packets.

This patch removes backwards compatibility for old ifenslave
binaries (ifenslave prior to verison 1.0.0).
I did not similarly modify ifenslave itself; with sysfs on the
horizon, I don't see that as being worthwhile.

The patch below is necessary to allow my Digital DS21143 Tulip rev 48
ethernet interface to work in a 10Mbit Half Duplex network. Without
it, the driver keeps retrying other modes in an endless loop. It seems
like someone already had the same problem with a rev 65 board :)

Subject: [PATCH 596/855] [netdrvr starfire] fix highmem and broken firmware
issues
Unfortunately, [your patch] might address the crash but doesn't address
the real problem. It turns out that the problem is one of padding
(the firmware cksum engine works only on 32-bit chunks, yuck), so
the special casing for length == 1 wasn't sufficient anyway.
This patch addresses the issue, as well the other issue of i386 +
CONFIG_HIGHMEM being broken. It is pretty much the same workaround
that Adaptec themselves used in their Windows driver. I have yet to
check if it fixes the problem when the skb is non-linear, but this
patch _will_ solve the problem for 99% of the users out there (those
not using sendfile).

Subject: [PATCH 604/855] [IPV4]: fib_trie root-node expansion
The patch below introduces special thresholds to keep root node in the trie
large. This gives a flatter tree at the cost of a modest memory increase.
Overall it seems to be gain and this was also proposed by one the authors
of the paper in recent a seminar.
Main table after loading 123 k routes.
Aver depth: 3.30
Max depth: 9
Root-node size 12 bits
Total size: 4044 kB
With the patch:
Aver depth: 2.78
Max depth: 8
Root-node size 15 bits
Total size: 4150 kB
An increase of 8-10% was seen in forwading performance for an rDoS attack.

Subject: [PATCH 608/855] [PATCH] bfs iget() abuses
bfs_fill_super() walks the inode table to get the bitmap of free inodes
and collect stats. It has no business using iget() for that - it's a
lot of extra work, extra icache pollution and more complex code.
Switched to walking the damn thing directly.
Note: that also allows to kill ->i_dsk_ino in there - separate patch if
Tigran can confirm that this field can be zero only for deleted inodes
(i.e. something that could only be found during that scan and not by
normal lookups).

Subject: [PATCH 610/855] [PATCH] uml: Fix sysrq-r support for skas mode
The old code had the IP and SP coming from the registers in the thread
struct, which are completely wrong since those are the userspace
registers. This fixes that by pulling the correct values from the
jmp_buf in which the kernel state of each thread is stored.

Subject: [PATCH 611/855] [ARM] 2949/1: Hynix h720x Run mode
Patch from Sascha Hauer
After coming out of idle mode the h720x goes into slow mode. Switch
it back to run mode.

Subject: [PATCH 612/855] [ARM] 2950/1: i.MX gpio setup function
Patch from Sascha Hauer
Current implementation of imx_gpio_mode does not allow to
configure all alternate routing possibilities of the i.MX. With
this patch every bit in the gpio setup registers has a
corresponding bit in the gpio_mode parameter, so every routing
should be possible now.

No need to align struct inet_ehash_bucket on a 8 bytes boundary.
On 32 bits Uniprocessor, that's a waste of 4 bytes per struct (50 %)
On other platforms, the attribute is useless, natual alignement is already 8.

Subject: [PATCH 617/855] [PATCH] x86_64: Drop global bit from early low
mappings
Drop global bit from early low mappings
Suggested by Linus, originally also proposed by Suresh.
This fixes a race condition with early start of udev, originally
tracked down by Suresh B. Siddha. The problem was that switching
to the user space VM would not clear the global low mappings
for the beginning of memory, which lead to memory corruption.
Drop the global bits.
The kernel mapping stays global because it should stay constant.

Subject: [PATCH 631/855] [PATCH] fix the breakage in sparc headers
If we switch extern inline to static inline, we'd better switch the
pre-declarations we use to say that these puppies have
__attribute_const__ on them.
Otherwise we get extern declaration followed by static inline one.
Which makes gcc unhappy, and for a good reason...

Subject: [PATCH 632/855] [PATCH] ppc: Fix timekeeping with HZ=250 on some Mac
models
Older Macs which uses the VIA chip timers to calibrate the timebase used
some code that wouldn't work if HZ wasn't divisible by 100...
This fixes it at least for 250. Not totally perfect but should be
enough for now (so it at least works with the default value which is now
250).
There is still a potential issue with the core using CLOCK_TICK_RATE to
maintain xtime and CLOCK_TICK_RATE value on ppc32 is pure crap, but that
is a different problem, this patch at least brings us back to our
previous situation.

Since changeset 98a82febb6340466824c3a453738d4fbd05db81a AX.25 is passing
received IP and ARP packets to the stack through netif_rx() but we don't
set the skb->mac.raw to right value which may result in a crash with
applications that use a packet socket.

Subject: [PATCH 641/855] [SPARC64]: Fix initrd when net booting.
By allocating early memory for the firmware page tables, we
can write over the beginning of the initrd image.
So what we do now is:
1) Read in firmware translations table while still on the
firmware's trap table.
2) Switch to Linux trap table.
3) Init bootmem.
4) Build firmware page tables using __alloc_bootmem().
And this keeps the initrd from being clobbered.

Subject: [PATCH 643/855] [IA64] Avoid kernel hang during CMC interrupt storm
I've noticed a kernel hang during a storm of CMC interrupts, which was
tracked down to the continual execution of the interrupt handler.
There's code in the CMC handler that's supposed to disable CMC
interrupts and switch to polling mode when it sees a bunch of CMCs.
Because disabling CMCs across all CPUs isn't safe in interrupt context,
the disable is done with a schedule_work(). But with continual CMC
interrupts, the schedule_work() never gets executed.
The following patch immediately disables CMC interrupts for the current
CPU. This then allows (at least) one CPU to ignore CMC interrupts,
execute the schedule_work() code, and disable CMC interrupts on the rest
of the CPUs.

Subject: [PATCH 645/855] [SCTP] Fix sctp_get{pl}addrs() API to work with
32-bit apps on 64-bit kernels.
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit
The old socket options are marked with a _OLD suffix so that the
existing 32-bit apps on 32-bit kernels do not break.

Subject: [PATCH 646/855] [SCTP] Fix SCTP socket options to work with 32-bit
apps on 64-bit kernels.
Adds alignment attribute to a few structures used with SCTP socket
options so that the sizes and offsets remain the same when built using
either 32 or 64 bit tools.

Subject: [PATCH 647/855] Avoid 'names_cache' memory leak with
CONFIG_AUDITSYSCALL
The nameidata "last.name" is always allocated with "__getname()", and
should always be free'd with "__putname()".
Using "putname()" without the underscores will leak memory, because the
allocation will have been hidden from the AUDITSYSCALL code.
Arguably the real bug is that the AUDITSYSCALL code is really broken,
but in the meantime this fixes the problem people see.
Reported by Robert Derr, patch by Rick Lindsley.

Subject: [PATCH 658/855] [ALSA] remove redundent assignment to the ac97 device
structure
AC97 Codec
Don't use dev.platform_data to store a reference to the containing
ac97_t structure. Such assignment is redundent since we can deduce the
ac97_t structure location from the contained device structure. This
sets platform_data free for other purposes.

AC97 Codec
A single call to the driver suspend/resume method for each device is
enough. The level and SUSPEND_*/RESUME_* arguments are deprecated and
said to be removed eventually anyway (no other subsystem are using them
anymore except platform devices).

Subject: [PATCH 677/855] [SPARC]: Fix p9100 framebuffer in 2.6
The attached patch fixes the p9100 framebuffer so that text is viewable
(not black on black, like it was before the patch). The linux logo
displays for a very short period of time, then is replaced by a grey
box. This leads me to believe that this framebuffer would have problems
in X, but since there hasn't been a weitek driver for X in several
millennia, this isn't something that I can confirm or deny.
But this patch does get color console working on my SPARCbook 3TX.

Subject: [PATCH 680/855] [PATCH] fix do_coredump() vs SIGSTOP race
Let's suppose we have 2 threads in thread group:
A - does coredump
B - has pending SIGSTOP
thread A thread B
do_coredump: get_signal_to_deliver:
lock(->sighand)
->signal->flags = SIGNAL_GROUP_EXIT
unlock(->sighand)
lock(->sighand)
signr = dequeue_signal()
->signal->flags |= SIGNAL_STOP_DEQUEUED
return SIGSTOP;
do_signal_stop:
unlock(->sighand)
coredump_wait:
zap_threads:
lock(tasklist_lock)
send SIGKILL to B
// signal_wake_up() does nothing
unlock(tasklist_lock)
lock(tasklist_lock)
lock(->sighand)
re-check sig->flags & SIGNAL_STOP_DEQUEUED, yes
set_current_state(TASK_STOPPED);
finish_stop:
schedule();
// ->state == TASK_STOPPED
wait_for_completion(&startup_done)
// waits for complete() from B,
// ->state == TASK_UNINTERRUPTIBLE
We can't wake up 'B' in any way:
SIGCONT will be ignored because handle_stop_signal() sees
->signal->flags & SIGNAL_GROUP_EXIT.
sys_kill(SIGKILL)->__group_complete_signal() will choose
uninterruptible 'A', so it can't help.
sys_tkill(B, SIGKILL) will be ignored by specific_send_sig_info()
because B already has pending SIGKILL.
This scenario is not possbile if 'A' does do_group_exit(), because
it sets sig->flags = SIGNAL_GROUP_EXIT and delivers SIGKILL to
subthreads atomically, holding both tasklist_lock and sighand->lock.
That means that do_signal_stop() will notice !SIGNAL_STOP_DEQUEUED
after re-locking ->sighand. And it is not possible to any other
thread to re-add SIGNAL_STOP_DEQUEUED later, because dequeue_signal()
can only return SIGKILL.
I think it is better to change do_coredump() to do sigaddset(SIGKILL)
and signal_wake_up() under sighand->lock, but this patch is much
simpler.

+ ===================
+ KEY REQUEST SERVICE
+ ===================
+
+The key request service is part of the key retention service (refer to
+Documentation/keys.txt). This document explains more fully how that the
+requesting algorithm works.
+
+The process starts by either the kernel requesting a service by calling
+request_key():
+
+ struct key *request_key(const struct key_type *type,
+ const char *description,
+ const char *callout_string);
+
+Or by userspace invoking the request_key system call:
+
+ key_serial_t request_key(const char *type,
+ const char *description,
+ const char *callout_info,
+ key_serial_t dest_keyring);
+
+The main difference between the two access points is that the in-kernel
+interface does not need to link the key to a keyring to prevent it from being
+immediately destroyed. The kernel interface returns a pointer directly to the
+key, and it's up to the caller to destroy the key.
+
+The userspace interface links the key to a keyring associated with the process
+to prevent the key from going away, and returns the serial number of the key to
+the caller.
+
+
+===========
+THE PROCESS
+===========
+
+A request proceeds in the following manner:
+
+ (1) Process A calls request_key() [the userspace syscall calls the kernel
+ interface].
+
+ (2) request_key() searches the process's subscribed keyrings to see if there's
+ a suitable key there. If there is, it returns the key. If there isn't, and
+ callout_info is not set, an error is returned. Otherwise the process
+ proceeds to the next step.
+
+ (3) request_key() sees that A doesn't have the desired key yet, so it creates
+ two things:
+
+ (a) An uninstantiated key U of requested type and description.
+
+ (b) An authorisation key V that refers to key U and notes that process A
+ is the context in which key U should be instantiated and secured, and
+ from which associated key requests may be satisfied.
+
+ (4) request_key() then forks and executes /sbin/request-key with a new session
+ keyring that contains a link to auth key V.
+
+ (5) /sbin/request-key execs an appropriate program to perform the actual
+ instantiation.
+
+ (6) The program may want to access another key from A's context (say a
+ Kerberos TGT key). It just requests the appropriate key, and the keyring
+ search notes that the session keyring has auth key V in its bottom level.
+
+ This will permit it to then search the keyrings of process A with the
+ UID, GID, groups and security info of process A as if it was process A,
+ and come up with key W.
+
+ (7) The program then does what it must to get the data with which to
+ instantiate key U, using key W as a reference (perhaps it contacts a
+ Kerberos server using the TGT) and then instantiates key U.
+
+ (8) Upon instantiating key U, auth key V is automatically revoked so that it
+ may not be used again.
+
+ (9) The program then exits 0 and request_key() deletes key V and returns key
+ U to the caller.
+
+This also extends further. If key W (step 5 above) didn't exist, key W would be
+created uninstantiated, another auth key (X) would be created [as per step 3]
+and another copy of /sbin/request-key spawned [as per step 4]; but the context
+specified by auth key X will still be process A, as it was in auth key V.
+
+This is because process A's keyrings can't simply be attached to
+/sbin/request-key at the appropriate places because (a) execve will discard two
+of them, and (b) it requires the same UID/GID/Groups all the way through.
+
+
+======================
+NEGATIVE INSTANTIATION
+======================
+
+Rather than instantiating a key, it is possible for the possessor of an
+authorisation key to negatively instantiate a key that's under construction.
+This is a short duration placeholder that causes any attempt at re-requesting
+the key whilst it exists to fail with error ENOKEY.
+
+This is provided to prevent excessive repeated spawning of /sbin/request-key
+processes for a key that will never be obtainable.
+
+Should the /sbin/request-key process exit anything other than 0 or die on a
+signal, the key under construction will be automatically negatively
+instantiated for a short amount of time.
+
+
+====================
+THE SEARCH ALGORITHM
+====================
+
+A search of any particular keyring proceeds in the following fashion:
+
+ (1) When the key management code searches for a key (keyring_search_aux) it
+ firstly calls key_permission(SEARCH) on the keyring it's starting with,
+ if this denies permission, it doesn't search further.
+
+ (2) It considers all the non-keyring keys within that keyring and, if any key
+ matches the criteria specified, calls key_permission(SEARCH) on it to see
+ if the key is allowed to be found. If it is, that key is returned; if
+ not, the search continues, and the error code is retained if of higher
+ priority than the one currently set.
+
+ (3) It then considers all the keyring-type keys in the keyring it's currently
+ searching. It calls key_permission(SEARCH) on each keyring, and if this
+ grants permission, it recurses, executing steps (2) and (3) on that
+ keyring.
+
+The process stops immediately a valid key is found with permission granted to
+use it. Any error from a previous match attempt is discarded and the key is
+returned.
+
+When search_process_keyrings() is invoked, it performs the following searches
+until one succeeds:
+
+ (1) If extant, the process's thread keyring is searched.
+
+ (2) If extant, the process's process keyring is searched.
+
+ (3) The process's session keyring is searched.
+
+ (4) If the process has a request_key() authorisation key in its session
+ keyring then:
+
+ (a) If extant, the calling process's thread keyring is searched.
+
+ (b) If extant, the calling process's process keyring is searched.
+
+ (c) The calling process's session keyring is searched.
+
+The moment one succeeds, all pending errors are discarded and the found key is
+returned.
+
+Only if all these fail does the whole thing fail with the highest priority
+error. Note that several errors may have come from LSM.
+
+The error priority is:
+
+ EKEYREVOKED > EKEYEXPIRED > ENOKEY
+
+EACCES/EPERM are only returned on a direct search of a specific keyring where
+the basal keyring does not grant Search permission.

Date: Fri, 7 Oct 2005 16:41:24 +0100
Subject: [PATCH 685/855] [PATCH] Keys: Possessor permissions should be
additive
This patch makes the possessor permissions on a key additive with
user/group/other permissions on the same key.
This permits extra rights to be granted to the possessor of a key without
taking away any rights conferred by them owning the key or having common group
membership.

Subject: [PATCH 687/855] [PATCH] gfp flags annotations - part 1
- added typedef unsigned int __nocast gfp_t;
- replaced __nocast uses for gfp flags with gfp_t - it gives exactly
the same warnings as far as sparse is concerned, doesn't change
generated code (from gcc point of view we replaced unsigned int with
typedef) and documents what's going on far better.

Subject: [PATCH 702/855] [PATCH] uml: restore include breakage, breaking
binary format of COW driver
Commit 44456d37b59d8e541936ed26d8b6e08d27e88ac1, between 2.6.13-rc3 and -rc4,
was a "nice cleanup" which broke something. Revert the offending part.
It broke because:
a) because this part doesn't fall under the description
b) the author didn't know what he was doing here
c) the author didn't try to compile the existing code and see that it worked
perfectly.
d) the author didn't ask us what was happening
e) you didn't either, and somebody there should have learned that UML is a bit
different.
In fact, UML is special in linking to host libc and using its includes.
In particular, since host includes always define both __BIG_ENDIAN and
__LITTLE_ENDIAN, ntohll() macros started thinking to be in a big-endian world;
and on-disk compatibility was broken.
Many thanks go to Nix for reporting the problem and correctly diagnosing an
endianness problem.
Btw, this patch restores the previous code, which worked; but the definitions
would be uncorrect if used in kernelspace files.
Next patch addresses that.

Subject: [PATCH 705/855] [PATCH] x86_64: Set up safe page tables during resume
The following patch makes swsusp avoid the possible temporary corruption
of page translation tables during resume on x86-64. This is achieved by
creating a copy of the relevant page tables that will not be modified by
swsusp and can be safely used by it on resume.
The problem is that during resume on x86-64 swsusp may temporarily
corrupt the page tables used for the direct mapping of RAM. If that
happens, a page fault occurs and cannot be handled properly, which leads
to the solid hang of the affected system. This leads to the loss of the
system's state from before suspend and may result in the loss of data or
the corruption of filesystems, so it is a serious issue. Also, it
appears to happen quite often (for me, as often as 50% of the time).
The problem is related to the fact that (at least) one of the PMD
entries used in the direct memory mapping (starting at PAGE_OFFSET)
points to a page table the physical address of which is much greater
than the physical address of the PMD entry itself. Moreover,
unfortunately, the physical address of the page table before suspend
(i.e. the one stored in the suspend image) happens to be different to
the physical address of the corresponding page table used during resume
(i.e. the one that is valid right before swsusp_arch_resume() in
arch/x86_64/kernel/suspend_asm.S is executed). Thus while the image is
restored, the "offending" PMD entry gets overwritten, so it does not
point to the right physical address any more (i.e. there's no page
table at the address pointed to by it, because it points to the address
the page table has been at during suspend). Consequently, if the PMD
entry is used later on, and it _is_ used in the process of copying the
image pages, a page fault occurs, but it cannot be handled in the normal
way and the system hangs.
In principle we can call create_resume_mapping() from
swsusp_arch_resume() (ie. from suspend_asm.S), but then the memory
allocations in create_resume_mapping(), resume_pud_mapping(), and
resume_pmd_mapping() must be made carefully so that we use _only_
NosaveFree pages in them (the other pages are overwritten by the loop in
swsusp_arch_resume()). Additionally, we are in atomic context at that
time, so we cannot use GFP_KERNEL. Moreover, if one of the allocations
fails, we should free all of the allocated pages, so we need to trace
them somehow.
All of this is done in the appended patch, except that the functions
populating the page tables are located in arch/x86_64/kernel/suspend.c
rather than in init.c. It may be done in a more elegan way in the
future, with the help of some swsusp patches that are in the works now.

Subject: [PATCH 706/855] [PATCH] uml: fix x86_64 with !CONFIG_FRAME_POINTER
UML/x86_64 doesn't run when built with frame pointers disabled. There
was an implicit frame pointer assumption in the stub segfault handler.
With frame pointers disabled, UML dies on handling its first page fault.
The container-of part of this is from Paolo Giarrusso <blaisorblade@yahoo.it>.

Date: Sun, 9 Oct 2005 10:37:47 +1000
Subject: [PATCH 708/855] [PATCH] ide: Workaround PM problem
The logic in ide_do_request() doesn't guarantee that both drives will be
serviced after a call. It may "forget" to service one in some
circumstances, including when one of the drive is suspended (it will
eventually fail to service the slave when the master is suspended for
example). This prevents the wakeup requests that gets queued on wakeup
from sleep from beeing serviced in some cases when 2 drives are sharing
an IDE bus.
The problem is deep enough in the way this code works (and there are
probably a few other problematic but rare corner cases) and fixing it
would require some major rethinking of the way IDE decides which channel
to service. This is not 2.6.14 material. However, in the meantime,
Bart has accepted this simple workaround that will fix the crash on
wakeup from sleep since this specific corner case is actually hitting
users to get into 2.6.14.

Subject: [PATCH 709/855] [PATCH] i386: fix stack alignment for signal handlers
This fixes the setup of the alignment of the signal frame, so that all
signal handlers are run with a properly aligned stack frame.
The current code "over-aligns" the stack pointer so that the stack frame
is effectively always mis-aligned by 4 bytes. But what we really want
is that on function entry ((sp + 4) & 15) == 0, which matches what would
happen if the stack were aligned before a "call" instruction.

Undo wrong change in global_flush_tlb. We need to flush the caches in all
cases, not just when pages were reverted. This was a bogus optimization
added earlier, but it was wrong.

Subject: [PATCH 716/855] [SPARC64]: Fix Ultra5, Ultra60, et al. boot failures.
On the boot processor, we need to do the move onto the Linux trap
table a little bit differently else we'll take unhandlable faults in
the firmware address space.
Previously we would do the following:
1) Disable PSTATE_IE in %pstate.
2) Set %tba by hand to sparc64_ttable_tl0
3) Initialize alternate, mmu, and interrupt global
trap registers.
4) Call prom_set_traptable()
That doesn't work very well actually with the way we boot the kernel
VM these days. It worked by luck on many systems because the firmware
accesses for the prom_set_traptable() call happened to be loaded into
the TLB already, something we cannot assume.
So the new scheme is this:
1) Clear PSTATE_IE in %pstate and set %pil to 15
2) Call prom_set_traptable()
3) Initialize alternate, mmu, and interrupt global
trap registers.
and this works quite well. This sequence has been moved into a
callable function in assembler named setup-trap_table(). The idea is
that eventually trampoline.S can use this code as well. That isn't
possible currently due to some complications, but eventually we should
be able to do it.
Thanks to Meelis Roos for the Ultra5 boot failure report.

Subject: [PATCH 717/855] [PATCH] Fix signal sending in usbdevio on async URB
completion
If a process issues an URB from userspace and (starts to) terminate
before the URB comes back, we run into the issue described above. This
is because the urb saves a pointer to "current" when it is posted to the
device, but there's no guarantee that this pointer is still valid
afterwards.
In fact, there are three separate issues:
1) the pointer to "current" can become invalid, since the task could be
completely gone when the URB completion comes back from the device.
2) Even if the saved task pointer is still pointing to a valid task_struct,
task_struct->sighand could have gone meanwhile.
3) Even if the process is perfectly fine, permissions may have changed,
and we can no longer send it a signal.
So what we do instead, is to save the PID and uid's of the process, and
introduce a new kill_proc_info_as_uid() function.

K8
Need to use long long, not long when RMWing a MSR. I think
it's harmless right now, but still should be better fixed
if AMD adds any bits in the upper 32bit of HWCR.
Bug was introduced with the TLB flush filter fix for i386

Subject: [PATCH 725/855] [NETFILTER] nfnetlink: use highest bit of nfa_type to
indicate nested TLV
As Henrik Nordstrom pointed out, all our efforts with "split endian" (i.e.
host byte order tags, net byte order values) are useless, unless a parser
can determine whether an attribute is nested or not.
This patch steals the highest bit of nfattr.nfa_type to indicate whether
the data payload contains a nested nfattr (1) or not (0).
This will break userspace compatibility, but luckily no kernel with
nfnetlink was released so far.

It breaks non-PCI builds, it's probably better to have a more

needs this is still questionable.

Subject: [PATCH 733/855] [IPSEC] Fix block size/MTU bugs in ESP
This patch fixes the following bugs in ESP:
* Fix transport mode MTU overestimate. This means that the inner MTU
is smaller than it needs be. Worse yet, given an input MTU which
is a multiple of 4 it will always produce an estimate which is not
a multiple of 4.
For example, given a standard ESP/3DES/MD5 transform and an MTU of
1500, the resulting MTU for transport mode is 1462 when it should
be 1464.
The reason for this is because IP header lengths are always a multiple
of 4 for IPv4 and 8 for IPv6.
* Ensure that the block size is at least 4. This is required by RFC2406
and corresponds to what the esp_output function does. At the moment
this only affects crypto_null as its block size is 1.

Subject: [PATCH 734/855] [NETFILTER]: Use only 32bit counters for
CONNTRACK_ACCT
Initially we used 64bit counters for conntrack-based accounting, since we
had no event mechanism to tell userspace that our counters are about to
overflow. With nfnetlink_conntrack, we now have such a event mechanism and
thus can save 16bytes per connection.

pSeries_irq_bus_setup is marked __devinit but references s7a_workaround
which is marked __initdata.
Depending on who got the memory for s7a_workaround (and if the value was
now positive), it was possible for PCI hotplugged devices to have 3
subtracted from their interrupt number. This would happen randomly and
caused me much confusion :)

Subject: [PATCH 744/855] [PATCH] dell_rbu: changes in packet update mechanism
In the current dell_rbu code ver 2.0 the packet update mechanism makes the
user app dump every individual packet in to the driver.
This adds in efficiency as every packet update makes the
/sys/class/firmware/dell_rbu/loading and data files to disappear and reappear
again. Thus the user app needs to wait for the files to reappear to dump
another packet. This slows down the packet update tremendously in case of
large number of packets. I am submitting a new patch for dell_rbu which will
change the way we do packet updates;
In the new method the user app will create a new single file which has already
packetized the rbu image and all the packets are now staged in this file.
This driver also creates a new entry in
/sys/devices/platform/dell_rbu/packet_size ; the user needs to echo the packet
size here before downloading the packet file.
The user should do the following:
create one single file which has all the packets stacked together.
echo the packet size in to /sys/devices/platform/dell_rbu/packet_size.
echo 1 > /sys/class/firmware/dell_rbu/loading
cat the packetfile > /sys/class/firmware/dell_rbu/data
echo 0 > /sys/class/firmware/dell_rbu/loading
The driver takes the file which came through /sys/class/firmware/dell_rbu/data
and takes chunks of paket_size data from it and place in contiguous memory.
This makes packet update process very efficient and fast. As all the packet
update happens in one single operation. The user can still read back the
downloaded file from /sys/devices/platform/dell_rbu/data.

Subject: [PATCH 745/855] [PATCH] v9fs: remove additional buffer allocation
from v9fs_file_read and v9fs_file_write
v9fs_file_read and v9fs_file_write use kmalloc to allocate buffers as big
as the data buffer received as parameter. kmalloc cannot be used to
allocate buffers bigger than 128K, so reading/writing data in chunks bigger
than 128k fails.
This patch reorganizes v9fs_file_read and v9fs_file_write to allocate only
buffers as big as the maximum data that can be sent in one 9P message.

Subject: [PATCH 746/855] [PATCH] nfsacl: Solaris VxFS compatibility fix
Here is a compatibility fix between Linux and Solaris when used with VxFS
filesystems: Solaris usually accepts acl entries in any order, but with
VxFS it replies with NFSERR_INVAL when it sees a four-entry acl that is not
in canonical form. It may also fail with other non-canonical acls -- I
can't tell, because that case never triggers: We only send non-canonical
acls when we fake up an ACL_MASK entry.
Instead of adding fake ACL_MASK entries at the end, inserting them in the
correct position makes Solaris+VxFS happy. The Linux client and server
sides don't care about entry order. The three-entry-acl special case in
which we need a fake ACL_MASK entry was handled in xdr_nfsace_encode. The
patch moves this into nfsacl_encode.

reported that it broke an existing application, and that madvise() works
without error on anonymous mappings on Solaris.
This means that madvise() will remain non-standards-compliant: we should
return -EBADF for all requests against non-file-backed vma's, but Linux only
does this for MADV_WILLNEED requests.

Subject: [PATCH 748/855] [PATCH] ppc highmem fix
I've noticed that the calculations for seg_size and nr_segs in
__dma_sync_page_highmem() (arch/ppc/kernel/dma-mapping.c) are wrong. The
incorrect calculations can result in either an oops or a panic when running
fsck depending on the size of the partition.
The problem with the seg_size calculation is that it can result in a
negative number if size is offset > size. The problem with the nr_segs
caculation is returns the wrong number of segments, e.g. it returns 1 when
size is 200 and offset is 4095, when it should return 2 or more.

Nir Tzachar <tzachar@cs.bgu.ac.il> points out that if an ELF file specifies a
zero-length bss at a whacky address, we cannot load that binary because
padzero() tries to zero out the end of the page at the whacky address, and
that may not be writeable.
See also http://bugzilla.kernel.org/show_bug.cgi?id=5411
So teach load_elf_binary() to skip the bss settng altogether if the elf file
has a zero-length bss segment.

Subject: [PATCH 754/855] [SPARC64]: Fix net booting on Ultra5
We were not doing alignment properly when remapping the kernel image.
What we want is a 4MB aligned physical address to map at KERNBASE.
Mistakedly we were 4MB aligning the virtual address where the kernel
initially sits, that's wrong.
Instead, we should PAGE align the virtual address, then 4MB align the
physical address result the prom gives to us.

Subject: [PATCH 755/855] [PATCH] uml: revert block driver use of host AIO
The patch to use host AIO support that I submitted early after 2.6.13 exposed
some problems in the block driver. I have fixes for these, but am not
comfortable putting them into 2.6.14 at this late date. So, this patch reverts
the use of host AIO.
I will resubmit the original patch, plus fixes to the driver after 2.6.14
in order to get a reasonable amount of testing before they're exposed to
the general public.

Subject: [PATCH 757/855] [PATCH] ppc32: Fix timekeeping
Interestingly enough, ppc32 had broken timekeeping for ages... It
worked, but probably drifted a bit more than could be explained by the
actual bad precision of the timebase calibration. We discovered that
recently when somebody figured out that the common code was using
CLOCK_TICK_RATE to correct the timekeeing, and ppc32 had a completely
bogus value for it.
This patch turns it into something saner. Probably not as good as doing
something based on the actual timebase frequency precision but I'll
leave that sort of math to others. This at least makes it better for
the common HZ values.

Subject: [PATCH 758/855] [PATCH] ppc32: Tell userland about lack of standard
TB
Glibc is about to get some new high precision timer stuff that relies on
the standard timebase of the PPC architecture.
However, some (rare & old) CPUs do not have such timebase and it is a
bit annoying to have your stuff just crash because you are running on
the wrong CPU...
This exposes to userland a CPU feature bit that tells that the current
processor doesn't have a standard timebase. It's negative logic so that
glibc will still "just work" on older kernels (it will just be unhappy
on those old CPUs but that doesn't really matter as distro tend to
update glibc & kernel at the same time).

Patch from Nicolas Pitre
Either no one is using an ARM710 with recent kernels, or all ARM710s
still in use are not afflicted by this swi bug. Nevertheless, the code
to work around the ARM710 swi bug is itself currently buggy since it
uses r8 as a pointer to S_PC while in fact it holds the spsr content
these days. Fix that, and simplify the code as well.

Patch from George G. Davis
When building for CPU_V6 targets, we should use -mtune=arm1136j-s rather
than -mtune=strongarm but fall back to the later in case someone is
using an older toolchain (although they should really upgrade instead).

The function serial_pxa_set_termios() is calling uart_update_timeout()

uart_update_timeout() expects the baud rate in this place.
This results in a bogus port->timeout which is proportional to the

Subject: [PATCH 770/855] [SPARC64]: Fix boot failures on SunBlade-150
The sequence to move over to the Linux trap tables from
the firmware ones needs to be more air tight. It turns
out that to be %100 safe we do need to be able to translate
OBP mappings in our TLB miss handlers early.
In order not to eat up a lot of kernel image memory with
static page tables, just use the translations array in
the OBP TLB miss handlers. That solves the bulk of the
problem.
Furthermore, to make sure the OBP TLB miss path will work
even before the fixed MMU globals are loaded, explicitly
load %g1 to TLB_SFSR at the beginning of the i-TLB and
d-TLB miss handlers.
To ease the OBP TLB miss walking of the prom_trans[] array,
we sort it then delete all of the non-OBP entries in there
(for example, there are entries for the kernel image itself
which we're not interested in at all).
We also save about 32K of kernel image size with this change.
Not a bad side effect :-)
There are still some reasons why trampoline.S can't use the
setup_trap_table() yet. The most noteworthy are:
1) OBP boots secondary processors with non-bias'd stack for
some reason. This is easily fixed by using a small bootup
stack in the kernel image explicitly for this purpose.
2) Doing a firmware call via the normal C call prom_set_trap_table()
goes through the whole OBP enter/exit sequence that saves and
restores OBP and Linux kernel state in the MMUs. This path
unfortunately does a "flush %g6" while loading up the OBP locked
TLB entries for the firmware call.
If we setup the %g6 in the trampoline.S code properly, that
is in the PAGE_OFFSET linear mapping, but we're not on the
kernel trap table yet so those addresses won't translate properly.
One idea is to do a by-hand firmware call like we do in the
early bootup code and elsewhere here in trampoline.S But this
fails as well, as aparently the secondary processors are not
booted with OBP's special locked TLB entries loaded. These
are necessary for the firwmare to processes TLB misses correctly
up until the point where we take over the trap table.
This does need to be resolved at some point.

Subject: [PATCH 771/855] [BRIDGE]: fix race on bridge del if
This fixes the RCU race on bridge delete interface. Basically,
the network device has to be detached from the bridge in the first
step (pre-RCU), rather than later. At that point, no more bridge traffic
will come in, and the other code will not think that network device
is part of a bridge.
This should also fix the XEN test problems.

net/ipv4/tcp_output.c:438!"
This is the second report of this bug. Unfortunately the first
reporter hasn't been able to reproduce it since to provide more
debugging info.
So let's apply this patch for 2.6.14 to
1) Make this non-fatal.
2) Provide the info we need to track it down.

Subject: [PATCH 778/855] [NETFILTER]: Fix OOPSes on machines with
discontiguous cpu numbering.
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit
Original patch by Harald Welte, with feedback from Herbert Xu
and testing by Sébastien Bernard.
EBTABLES, ARP tables, and IP/IP6 tables all assume that cpus
are numbered linearly. That is not necessarily true.
This patch fixes that up by calculating the largest possible
cpu number, and allocating enough per-cpu structure space given
that.

Subject: [PATCH 779/855] [NET]: Disable NET_SCH_CLK_CPU for SMP x86 hosts
Opterons with frequency scaling have fully unsynchronized TSCs
running at different frequencies, so using TSCs there is not a good idea.
Also some other x86 boxes have this problem. gettimeofday should be good
enough, so just disable it.

be lost due to memory pressure or process' receiving queue overflowed,
so caller is warned must be prepared. That is why struct cn_msg [main
connector's message header] contains u32 seq and u32 ack fields.
+
+/*****************************************/
+Userspace usage.
+/*****************************************/
+2.6.14 has a new netlink socket implementation, which by default does not
+allow to send data to netlink groups other than 1.
+So, if to use netlink socket (for example using connector)
+with different group number userspace application must subscribe to
+that group. It can be achieved by following pseudocode:
+
+s = socket(PF_NETLINK, SOCK_DGRAM, NETLINK_CONNECTOR);
+
+l_local.nl_family = AF_NETLINK;
+l_local.nl_groups = 12345;
+l_local.nl_pid = 0;
+
+if (bind(s, (struct sockaddr *)&l_local, sizeof(struct sockaddr_nl)) == -1) {
+ perror("bind");
+ close(s);
+ return -1;
+}
+
+{
+ int on = l_local.nl_groups;
+ setsockopt(s, 270, 1, &on, sizeof(on));
+}
+
+Where 270 above is SOL_NETLINK, and 1 is a NETLINK_ADD_MEMBERSHIP socket
+option. To drop multicast subscription one should call above socket option
+with NETLINK_DROP_MEMBERSHIP parameter which is defined as 0.
+
+2.6.14 netlink code only allows to select a group which is less or equal to
+the maximum group number, which is used at netlink_kernel_create() time.
+In case of connector it is CN_NETLINK_USERS + 0xf, so if you want to use
+group number 12345, you must increment CN_NETLINK_USERS to that number.
+Additional 0xf numbers are allocated to be used by non-in-kernel users.
+
+Due to this limitation, group 0xffffffff does not work now, so one can
+not use add/remove connector's group notifications, but as far as I know,
+only cn_test.c test module used it.
+
+Some work in netlink area is still being done, so things can be changed in
+2.6.15 timeframe, if it will happen, documentation will be updated for that
+kernel.

Subject: [PATCH 783/855] [SPARC64]: Eliminate PCI IOMMU dma mapping size
limit.
The hairy fast allocator in the sparc64 PCI IOMMU code
has a hard limit of 256 pages. Certain devices can
exceed this when performing very large I/Os.
So replace with a more simple allocator, based largely
upon the arch/ppc64/kernel/iommu.c code.
Signed-off-by: David S. Miller <davem@davemloft.net>

Subject: [PATCH 784/855] [ARM] 3009/1: S3C2410 - io.h offsets too large for
LDRH/STRH
Patch from Ben Dooks
The __inwc/__outwc calls are capable of creating
LDRH and STRH instructions with offsets over 8bits
as GCC does not have a constraint for an 8bit
offset.

Patch from Deepak Saxena
This patch fixes L7200 so that it builds in 2.6.latest. I do not
have the hardware so don't know if it actually still works, but
the changes are fairly trivial. I am not even sure if anyone
still maintains, uses, or cares about this machine type.

Subject: [PATCH 792/855] [SPARC64]: Fix powering off on SMP.
Doing a "SUNW,stop-self" firmware call on the other cpus is not the
correct thing to do when dropping into the firmware for a halt,
reboot, or power-off.
For now, just do nothing to quiet the other cpus, as the system should
be quiescent enough. Later we may decide to implement smp_send_stop()
like the other SMP platforms do.
Based upon a report from Christopher Zimmermann.

Subject: [PATCH 800/855] [PATCH] wireless/airo: Build fix
The aironet PCI driver has a build dependency on ISA that prevent the
driver to compile on systems that doesn't support ISA, like x86_64. The
driver really doesn't depend on ISA, it does some ISA stuff in the
initialization code, since the driver supports both ISA and PCI cards. So
the driver should depend on ISA_DMA_API to build on all systems, and this
will not hurt PCI at all.

Subject: [PATCH 811/855] [PATCH]: highest_possible_processor_id() has to be a
macro
... otherwise, things like alpha and sparc64 break and break
badly. They define cpu_possible_map to something else in smp.h
*AFTER* having included cpumask.h.
If that puppy is a macro, expansion will happen at the actual
caller, when we'd already seen #define cpu_possible_map ... and we will
get the right thing used.
As an inline helper it will be tokenized before we get to that
define and that's it; no matter what we define later, it won't affect
anything. We get modules with dependency on cpu_possible_map instead
of the right symbol (phys_cpu_present_map in case of sparc64), or outright
link errors if they are built-in.

Subject: [PATCH 812/855] Fix memory ordering bug in page reclaim
As noticed by Nick Piggin, we need to make sure that we check the page
count before we check for PageDirty, since the dirty check is only valid
if the count implies that we're the only possible ones holding the page.
We always did do this, but the code needs a read-memory-barrier to make
sure that the orderign is also honored by the CPU.
(The writer side is ordered due to the atomic decrement and test on the
page count, see the discussion on linux-kernel)

Subject: [PATCH 813/855] [PATCH] list: add missing rcu_dereference on first
element
It seems that all the list_*_rcu primitives are missing a memory barrier
on the very first dereference. For example,
#define list_for_each_rcu(pos, head) \
for (pos = (head)->next; prefetch(pos->next), pos != (head); \
pos = rcu_dereference(pos->next))
It will go something like:
pos = (head)->next
prefetch(pos->next)
pos != (head)
do stuff
We're missing a barrier here.
pos = rcu_dereference(pos->next)
fetch pos->next
barrier given by rcu_dereference(pos->next)
store pos
Without the missing barrier, the pos->next value may turn out to be stale.
In fact, if "do stuff" were also dereferencing pos and relying on
list_for_each_rcu to provide the barrier then it may also break.
So here is a patch to make sure that we have a barrier for the first
element in the list.

Subject: [PATCH 814/855] [PATCH] SVGATextMode fix
Fix bug 5441.
I didn't know about messy programs like svgatextmode... Couldn't this be
integrated in some linux/drivers/video/console/svgacon.c ?... So because
of the existence of the svgatextmode program, the kernel is not supposed to
touch to CRT_OVERFLOW/SYNC_END/DISP/DISP_END/OFFSET ?
Disabling the check in vgacon_resize() might help indeed, but I'm really
not sure whether it will work for any chipset: in my patch, CRT registers
are set at each console switch, since stty rows/cols apply to consoles
separately...
The attached solution is to keep the test, but if it fails, we assume that
the caller knows what it does (i.e. it is svgatextmode) and then disable
any further call to vgacon_doresize. Svgatextmode is usually used to
_expand_ the display, not to shrink it. And it is harmless in the case of
a too big stty rows/cols: the display will just be cropped. I tested it on
my laptop, and it works fine with svgatextmode.
A better solution would be that svgatextmode explicitely tells the kernel
not to care about video timing, but for this an interface needs be defined
and svgatextmode be patched.

Subject: [PATCH 815/855] [PATCH] fix vpx3220 offset issue in SECAM
Fix bug #5404 in kernel bugzilla.
It basically updates the vpx3220 initialization tables with some newer
values that we've had in CVS for a while (and that, for some reason, never
ended up in the kernel... must've gotten lost). Those fix a ~16 pixels
noise at the top of the picture in at least SECAM, although (now that I
think about it) PAL was probably affected, also.

Fix the fact that the svideo input will only give input in black/white in
some circumstances. Reason is that in the PCI controller driver (zr36067),
after setting input, we reset norm, which overwrites the input register
with the default. This patch makes it always set the correct value for the
input when changing norm.

Subject: [PATCH 817/855] Increase default RCU batching sharply
Dipankar made RCU limit the batch size to improve latency, but that
approach is unworkable: it can cause the RCU queues to grow without
bounds, since the batch limiter ended up limiting the callbacks.
So make the limit much higher, and start planning on instead limiting
the batch size by doing RCU callbacks more often if the queue looks like
it might be growing too long.

Increased use of scatter-gather by usb-storage driver after 2.6.13 has
exposed a buggy codepath in isp116x-hcd, which was probably never
visited before: bug happened only for those urbs, for which
URB_SHORT_NOT_OK was set AND short transfer occurred.
The fix attached was tested in 2 ways: (a) it fixed failing
initialization of a flash drive with an embedded hub; (b) the fix was
tested with 'usbtest' against a modified g_zero driver (on top of
net2280), which generated short bulk IN transfers of various lengths
including multiples and non-multiples of max_packet_length.

Subject: [PATCH 819/855] [PATCH] USB: fix bug in handling of highspeed usb HID
devices
During the development of an USB device I found a bug in the handling of
Highspeed HID devices in the kernel.
What happened?
Highspeed HID devices are correctly recognized and enumerated by the
kernel. But even if usbhid kernel module is loaded, no HID reports are
received by the kernel.
The output of the hardware USB analyzer told me that the host doesn't
even poll for interrupt IN transfers (even the "interrupt in" USB
transfer are polled by the host).
After some debugging in hid-core.c I've found the reason.
In case of a highspeed device, the endpoint interval is re-calculated in
driver/usb/input/hid-core.c:
line 1669:
/* handle potential highspeed HID correctly */
interval = endpoint->bInterval;
if (dev->speed == USB_SPEED_HIGH)
interval = 1 << (interval - 1);
Basically this calculation is correct (refer to USB 2.0 spec, 9.6.6).
This new calculated value of "interval" is used as input for
usb_fill_int_urb:
line 1685:
usb_fill_int_urb(hid->urbin, dev, pipe, hid->inbuf, 0,
hid_irq_in, hid, interval);
Unfortunately the same calculation as above is done a second time in
usb_fill_int_urb in the file include/linux/usb.h:
line 933:
if (dev->speed == USB_SPEED_HIGH)
urb->interval = 1 << (interval - 1);
else
urb->interval = interval;
This means, that if the endpoint descriptor (of a high speed device)
specifies e.g. bInterval = 7, the urb->interval gets the value:
hid-core.c: interval = 1 << (7-1) = 0x40 = 64
urb->interval = 1 << (interval -1) = 1 << (63) = integer overflow
Because of this the value of urb->interval is sometimes negative and is
rejected in core/urb.c:
line 353:
/* too small? */
if (urb->interval <= 0)
return -EINVAL;
The conclusion is, that the recalculaton of the interval (which is
necessary for highspeed) should not be made twice, because this is
simply wrong. ;-)
Re-calculation in usb_fill_int_urb makes more sense, because it is the
most general approach. So it would make sense to remove it from
hid-core.c.
Because in hid-core.c the interval variable is only used for calling
usb_fill_int_urb, it is no problem to remove the highspeed
re-calculation in this file.

This fixes an issue where some modular configurations would not cause

This makes call_rcu() keep track of how many events there are on the RCU

Subject: [PATCH 829/855] [PATCH] aio: revert lock_kiocb()
lock_kiocb() was introduced to serialize retrying and cancellation. In the
process of doing so it tried to sleep waiting for KIF_LOCKED while holding
the ctx_lock spinlock. Recent fixes have ensured that multiple concurrent
retries won't be attempted for a given iocb. Cancel has other problems and
has no significant in-tree users that have been complaining about it. So
for the immediate future we'll revert sleeping with the lock held and will
address proper cancellation and retry serialization in the future.

When interrupt 0 occur:

o if CONFIG_CPU_IXP46X is set, codes in upper interrupt handling will be trigerred. But since this is not supper interrupt, the "cmp" in the upper interrupt handling portion will set the Z flag and return

Subject: [PATCH 836/855] [PATCH] vesafb: Fix display corruption on display
blank
Reported by: Bob Tracy <rct@gherkin.frus.com>
"...I've got a Toshiba notebook (730XCDT -- Pentium 150MMX) for which
I'm using the Vesa FB driver. When the machine has been idle for some
time and the driver attempts to powerdown the display, rather than the
display going blank, it goes gray with several strange lines. When I
hit the "shift" key or other-wise wake up the display, the old video
state is not fully restored..."
vesafb recently added a blank method which has only 2 states, powerup and
powerdown. The powerdown state is used for all blanking levels, but in his
case, powerdown does not work correctly for higher levels of display
powersaving. Thus, for intermediate power levels, use software blanking,
and use only hardware blanking for an explicit powerdown.

Subject: [PATCH 837/855] [ARM] 3023/1: pxa-regs: Typo in ARM pxa register

Patch from Paul Schulz
The following trivial patch is to fix what looks like a typo in the PXA register
definitions. The correction comes directly from the definition in the
Intel Documentation.
http://www.intel.com/design/pca/applicationsprocessors/manuals/278693.htm
Intel(R) PXA 255 Processor - Developers Manual - Jan 2004 - Page 12-33
Neither 'UDCCS_IO_ROF' or 'UDCCS_IO_DME' are currently used elseware
in the main code (from grep of tree)... The current definitions have been
in the code since at lease 2.4.7.

Subject: [PATCH 838/855] [PATCH] Handle spurious page fault for hugetlb region
The hugetlb pages are currently pre-faulted. At the time of mmap of
hugepages, we populate the new PTEs. It is possible that HW has already
cached some of the unused PTEs internally. These stale entries never
get a chance to be purged in existing control flow.
This patch extends the check in page fault code for hugepages. Check if
a faulted address falls with in size for the hugetlb file backing it.
We return VM_FAULT_MINOR for these cases (assuming that the arch
specific page-faulting code purges the stale entry for the archs that
need it).

Subject: [PATCH 840/855] [PATCH] Fix cpu timers exit deadlock and races
Oleg Nesterov reported an SMP deadlock. If there is a running timer
tracking a different process's CPU time clock when the process owning
the timer exits, we deadlock on tasklist_lock in posix_cpu_timer_del via
exit_itimers.
That code was using tasklist_lock to check for a race with __exit_signal
being called on the timer-target task and clearing its ->signal.
However, there is actually no such race. __exit_signal will have called
posix_cpu_timers_exit and posix_cpu_timers_exit_group before it does
that. Those will clear those k_itimer's association with the dying
task, so posix_cpu_timer_del will return early and never reach the code
in question.
In addition, posix_cpu_timer_del called from exit_itimers during execve
or directly from timer_delete in the process owning the timer can race
with an exiting timer-target task to cause a double put on timer-target
task struct. Make sure we always access cpu_timers lists with sighand
lock held.

hugetlbfs allows truncation of its files (should it?), but hugetlb.c often
forgets that: crashes and misaccounting ensue.
copy_hugetlb_page_range better grab the src page_table_lock since we don't
want to guess what happens if concurrently truncated. unmap_hugepage_range
rss accounting must not assume the full range was mapped. follow_hugetlb_page
must guard with page_table_lock and be prepared to exit early.
Restyle copy_hugetlb_page_range with a for loop like the others there.

Subject: [PATCH 843/855] [PATCH] raw1394: fix locking in the presence of SMP
and interrupts
Changes all spinlocks that can be held during an irq handler to disable
interrupts while the lock is held. Changes spin_[un]lock_irq to use the
irqsave/irqrestore variants for robustness and readability.
In raw1394.c:handle_iso_listen(), don't grab host_info_lock at all -- we're
not accessing host_info_list or host_count, and holding this lock while
trying to tasklet_kill the iso tasklet this can cause an ABBA deadlock if
ohci:dma_rcv_tasklet is running and tries to grab host_info_lock in
raw1394.c:receive_iso. Test program attached reliably deadlocks all SMP
machines I have been able to test without this patch.

Subject: [PATCH 844/855] [PATCH] Three one-liners in md.c
The main problem fixes is that in certain situations stopping md arrays may
take longer than you expect, or may require multiple attempts. This would
only happen when resync/recovery is happening.
This patch fixes three vaguely related bugs.
1/ The recent change to use kthreads got the setting of the
process name wrong. This fixes it.
2/ The recent change to use kthreads lost the ability for
md threads to be signalled with SIG_KILL. This restores that.
3/ There is a long standing bug in that if:
- An array needs recovery (onto a hot-spare) and
- The recovery is being blocked because some other array being
recovered shares a physical device and
- The recovery thread is killed with SIG_KILL
Then the recovery will appear to have completed with no IO being
done, which can cause data corruption.
This patch makes sure that incomplete recovery will be treated as
incomplete.
Note that any kernel affected by bug 2 will not suffer the problem of bug
3, as the signal can never be delivered. Thus the current 2.6.14-rc
kernels are not susceptible to data corruption. Note also that if arrays
are shutdown (with "mdadm -S" or "raidstop") then the problem doesn't
occur. It only happens if a SIGKILL is independently delivered as done by
'init' when shutting down.

Subject: [PATCH 847/855] [PATCH] Threads shouldn't inherit PF_NOFREEZE
The PF_NOFREEZE process flag should not be inherited when a thread is
forked. This patch (as585) removes the flag from the child.
This problem is starting to show up more and more as drivers turn to the
kthread API instead of using kernel_thread(). As a result, their kernel
threads are now children of the kthread worker instead of modprobe, and
they inherit the PF_NOFREEZE flag. This can cause problems during system
suspend; the kernel threads are not getting frozen as they ought to be.

Subject: [PATCH 850/855] [PATCH] swiotlb: make sure initial DMA allocations
really are in DMA memory
This introduces a limit parameter to the core bootmem allocator; The new
parameter indicates that physical memory allocated by the bootmem
allocator should be within the requested limit.
We also introduce alloc_bootmem_low_pages_limit, alloc_bootmem_node_limit,
alloc_bootmem_low_pages_node_limit apis, but alloc_bootmem_low_pages_limit
is the only api used for swiotlb.
The existing alloc_bootmem_low_pages() api could instead have been
changed and made to pass right limit to the core allocator. But that
would make the patch more intrusive for 2.6.14, as other arches use
alloc_bootmem_low_pages(). We may be done that post 2.6.14 as a
cleanup.
With this, swiotlb gets memory within 4G for both x86_64 and ia64
arches.

Subject: [PATCH 852/855] [PATCH] scsi_error thread exits in TASK_INTERRUPTIBLE
state.
Found in the -rt patch set. The scsi_error thread likely will be in the
TASK_INTERRUPTIBLE state upon exit. This patch fixes this bug.

Subject: [PATCH 853/855] [PATCH] build fix for uml/amd64
Missing half of the [PATCH] uml: Fix sysrq-r support for skas mode
We need to remove these (UPT_[DEFG]S) from the read side as well as the
write one - otherwise it simply won't build.

The -rc4 release was supposed to be the last -rc, but here goes. The
RCU fixes and the swiotlb changes need an -rc for final testing.

Subject: [PATCH 855/855] [PATCH] Fix handling spurious page fault for hugetlb
region
This reverts commit 3359b54c8c07338f3a863d1109b42eebccdcf379 and
replaces it with a cleaner version that is purely based on page table
operations, so that the synchronization between inode size and hugetlb
mappings becomes moot.
