30 Sep '24

From: Roland Xu <mu001999(a)outlook.com> stable inclusion from stable-v6.6.51 commit 85f03ca98e07cd0786738b56ae73740bce0ac27f category: bugfix bugzilla: https://gitee.com/src-openeuler/kernel/issues/IAU9M4 CVE: CVE-2024-46829 Reference: https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git/commit/?id… -------------------------------- commit d33d26036a0274b472299d7dcdaa5fb34329f91b upstream. rt_mutex_handle_deadlock() is called with rt_mutex::wait_lock held. In the good case it returns with the lock held and in the deadlock case it emits a warning and goes into an endless scheduling loop with the lock held, which triggers the 'scheduling in atomic' warning. Unlock rt_mutex::wait_lock in the dead lock case before issuing the warning and dropping into the schedule for ever loop.

[PATCH OLK-6.6] dma-buf: heaps: Fix off-by-one in CMA heap fault handler

From: "T.J. Mercier" <tjmercier(a)google.com> mainline inclusion from mainline-v6.11 commit ea5ff5d351b520524019f7ff7f9ce418de2dad87 category: bugfix bugzilla: https://gitee.com/src-openeuler/kernel/issues/IAU9M8 CVE: CVE-2024-46852 Reference: https://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git/commit/?… -------------------------------- Until VM_DONTEXPAND was added in commit 1c1914d6e8c6 ("dma-buf: heaps: Don't track CMA dma-buf pages under RssFile") it was possible to obtain a mapping larger than the buffer size via mremap and bypass the overflow check in dma_buf_mmap_internal. When using such a mapping to attempt to fault past the end of the buffer, the CMA heap fault handler also checks the fault offset against the buffer size, but gets the boundary wrong by 1. Fix the boundary check so that we don't read off the end of the pages array and insert an arbitrary page in the mapping.

[PATCH OLK-6.6] spi: rockchip: Resolve unbalanced runtime PM / system PM handling
by Zheng Zucheng 30 Sep '24

30 Sep '24

From: Brian Norris <briannorris(a)chromium.org> stable inclusion from stable-v6.6.51 commit d034bff62faea1a2219e0d2f3d17263265f24087 category: bugfix bugzilla: https://gitee.com/src-openeuler/kernel/issues/IAU9NV CVE: CVE-2024-46846 Reference: https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git/commit/?id… -------------------------------- commit be721b451affbecc4ba4eaac3b71cdbdcade1b1b upstream. Commit e882575efc77 ("spi: rockchip: Suspend and resume the bus during NOIRQ_SYSTEM_SLEEP_PM ops") stopped respecting runtime PM status and simply disabled clocks unconditionally when suspending the system. This causes problems when the device is already runtime suspended when we go to sleep -- in which case we double-disable clocks and produce a WARNing. Switch back to pm_runtime_force_{suspend,resume}(), because that still seems like the right thing to do, and the aforementioned commit makes no explanation why it stopped using it. Also, refactor some of the resume() error handling, because it's not actually a good idea to re-disable clocks on failure.

[PATCH OLK-5.10] perf cpumap: Wrapper for CPU map indices
by Yushan Wang 30 Sep '24

30 Sep '24

driver inclusion category: feature bugzilla: https://gitee.com/openeuler/kernel/issues/IAQFZR CVE: NA ---------------------------------------------------------------------- Linux mainline changed the type of perf CPU map into struct perf_cpu to avoid confuses of CPU maps from cpu. The change affects a lot of infrastructures of Perf tool which this patchset depends on to fix perf undesirably scrutinizing events on offline CPUs issue[1]. This patch, with the purpose of adapting of following patches from Linux mainline to openeuler, is a mere copy of the patch [2] which changes the type of perf CPU map with careful refaction of affected code.

[PATCH OLK-6.6] scsi: lpfc: Handle mailbox timeouts in lpfc_get_sfp_info
by Zheng Qixing 30 Sep '24

30 Sep '24

From: Justin Tee <justin.tee(a)broadcom.com> mainline inclusion from mainline-v6.11-rc1 commit ede596b1434b57c0b3fd5c02b326efe5c54f6e48 category: bugfix bugzilla: https://gitee.com/src-openeuler/kernel/issues/IAU9N8 CVE: CVE-2024-46842 Reference: https://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git/commit/?… -------------------------------- The MBX_TIMEOUT return code is not handled in lpfc_get_sfp_info and the routine unconditionally frees submitted mailbox commands regardless of return status. The issue is that for MBX_TIMEOUT cases, when firmware returns SFP information at a later time, that same mailbox memory region references previously freed memory in its cmpl routine. Fix by adding checks for the MBX_TIMEOUT return code. During mailbox resource cleanup, check the mbox flag to make sure that the wait did not timeout. If the MBOX_WAKE flag is not set, then do not free the resources because it will be freed when firmware completes the mailbox at a later time in its cmpl routine. Also, increase the timeout from 30 to 60 seconds to accommodate boot scripts requiring longer timeouts.

This issue arises when EHT-PHY capabilities shows support for a bandwidth and MCS-NSS set for that particular bandwidth is filled by zeros and due to this, driver obtains peer_nss as 0 and sending this value to firmware causes crash. Address this issue by implementing a validation step for the peer_nss value before passing it to the firmware. If the value is greater than zero, proceed with forwarding it to the firmware. However, if the value is invalid, reject the association request to prevent potential firmware crashes.
