[ Upstream commit a861790afaa8b6369eee8a88c5d5d73f5799c0c6 ] iscsit_tpg_check_network_portal() has nested for_each loops and is supposed to return true when a match is found.

commit aec12836e7196e4d360b2cbf20cf7aa5139ad2ec upstream. When setting up autonegotiation for 88E1118R and compatible PHYs, a software reset of PHY is issued before setting up polarity. This is incorrect as changes of MDI Crossover Mode bits are disruptive to the normal operation and must be followed by a software reset to take effect. Let's patch m88e1118_config_aneg() to fix the issue mentioned before by invoking software reset of the PHY just after setting up MDI-x polarity.

commit fe4f57bf7b585dca58f1496c4e2481ecbae18126 upstream. It is mandatory for a software to issue a reset upon modifying RGMII Receive Timing Control and RGMII Transmit Timing Control bit fields of MAC Specific Control register 2 (page 2, register 21) otherwise the changes won't be perceived by the PHY (the same is applicable for a lot of other registers). Not setting the RGMII delays on the platforms that imply it' being done on the PHY side will consequently cause the traffic loss. We discovered that the denoted soft-reset is missing in the m88e1121_config_aneg() method for the case if the RGMII delays are modified but the MDIx polarity isn't changed or the auto-negotiation is left enabled, thus causing the traffic loss on our platform with Marvell Alaska 88E1510 installed. Let's fix that by issuing the soft-reset if the delays have been actually set in the m88e1121_config_aneg_rgmii_delays() method.

commit bb8e52e4906f148c2faf6656b5106cf7233e9301 upstream. Commit c2426d2a ("ima: added support for new kernel cmdline parameter ima_template_fmt") introduced an additional check on the ima_template variable to avoid multiple template selection. Unfortunately, ima_template could be also set by the setup function of the ima_hash= parameter, when it calls ima_template_desc_current(). This causes attempts to choose a new template with ima_template= or with ima_template_fmt=, after ima_hash=, to be ignored. Achieve the goal of the commit mentioned with the new static variable template_setup_done, so that template selection requests after ima_hash= are not ignored. Finally, call ima_init_template_list(), if not already done, to initialize the list of templates before lookup_template_desc() is called. Reported-by:

commit 9aa422ad326634b76309e8ff342c246800621216 upstream. The function tipc_mon_rcv() allows a node to receive and process domain_record structs from peer nodes to track their views of the network topology. This patch verifies that the number of members in a received domain record does not exceed the limit defined by MAX_MON_DOMAIN, something that may otherwise lead to a stack overflow. tipc_mon_rcv() is called from the function tipc_link_proto_rcv(), where we are reading a 32 bit message data length field into a uint16. To avert any risk of bit overflow, we add an extra sanity check for this in that function. We cannot see that happen with the current code, but future designers being unaware of this risk, may introduce it by allowing delivery of very large (> 64k) sk buffers from the bearer layer. This potential problem was identified by Eric Dumazet. This fixes CVE-2022-0435 Reported-by:

commit bd2db32e7c3e35bd4d9b8bbff689434a50893546 upstream. It was reported that the mmc host structure could be accessed after it was freed in moxart_remove(), so fix this by saving the base register of the device and using it instead of the pointer dereference.

commit eda0cf1202acf1ef47f93d8f92d4839213431424 upstream. Add a specific test for the reload issue fixed with commit 23c54263efd7cb ("netfilter: nft_set_pipapo: allocate pcpu scratch maps on clone"). Add to set, then flush set content + restore without other add/remove in the transaction. On kernels before the fix, this test case fails: net,mac with reload [FAIL] Signed-off-by:Florian Westphal <fw@strlen.de> Reviewed-by:

commit 2bdfd2825c9662463371e6691b1a794e97fa36b4 upstream. It was found that a "suspicious RCU usage" lockdep warning was issued with the rcu_read_lock() call in update_sibling_cpumasks(). It is because the update_cpumasks_hier() function may sleep. So we have to release the RCU lock, call update_cpumasks_hier() and reacquire it afterward. Also add a percpu_rwsem_assert_held() in update_sibling_cpumasks() instead of stating that in the comment. Fixes: 4716909c ("cpuset: Track cpusets that use parent's effective_cpus") Signed-off-by:

commit 4223f86512877b04c932e7203648b37eec931731 upstream. Make MediaTek MT753x DSA driver enable MediaTek Gigabit PHYs driver to properly control MT7530 and MT7531 switch PHYs. A noticeable change is that the behaviour of switchport interfaces going up-down-up-down is no longer there.

commit cdce59a1549190b66f8e3fe465c2b2f714b98a94 upstream. Current code does not fully takes care of krealloc() error case, which could lead to silent memory corruption or a kernel bug. This patch fixes that. Also it cleans up some duplicated error handling logic from various functions in fast_commit.c file. Reported-by:

commit 897026aaa73eb2517dfea8d147f20ddb0b813044 upstream. While running "./check -I 200 generic/475" it sometimes gives below kernel BUG().

commit 31a074a0c62dc0d2bfb9b543142db4fe27f9e5eb upstream. For now in ext4_mb_new_blocks_simple, if we found a block which should be excluded then will switch to next group, this may probably cause 'group' run out of range. Change to check next block in the same group when get a block should be excluded. Also change the search range to EXT4_CLUSTERS_PER_GROUP and add error checking. Signed-off-by:

commit 599ea31d13617c5484c40cdf50d88301dc351cfc upstream. During fast commit replay procedure, we clear inode blocks bitmap in ext4_ext_clear_bb(), this may cause ext4_mb_new_blocks_simple() allocate blocks still in use. Make ext4_fc_record_regions() also record physical disk regions used by inodes during replay procedure. Then ext4_mb_new_blocks_simple() can excludes these blocks in use. Signed-off-by:
