[PATCH 5.15.y] scsi: lpfc: Fix a possible data race in lpfc_unregister_fcf_rescan()

by bin.lan.cn＠windriver.com

From: Tuo Li <islituo(a)gmail.com> [ Upstream commit 0e881c0a4b6146b7e856735226208f48251facd8 ] The variable phba->fcf.fcf_flag is often protected by the lock phba->hbalock() when is accessed. Here is an example in lpfc_unregister_fcf_rescan(): spin_lock_irq(&phba->hbalock); phba->fcf.fcf_flag |= FCF_INIT_DISC; spin_unlock_irq(&phba->hbalock); However, in the same function, phba->fcf.fcf_flag is assigned with 0 without holding the lock, and thus can cause a data race: phba->fcf.fcf_flag = 0; To fix this possible data race, a lock and unlock pair is added when accessing the variable phba->fcf.fcf_flag.

[PATCH] bcachefs: Add error handling for zlib_deflateInit2()

by Wentao Liang

In attempt_compress(), the return value of zlib_deflateInit2() needs to be checked. A proper implementation can be found in pstore_compress(). Add an error check and return 0 immediately if the initialzation fails.

Don't backport 757b000f7b93 ("timekeeping: Fix possible inconsistencies in _COARSE clockids")

by Thomas Gleixner

Hi! It turned out that this commit causes a regression for adjtimex() users, so it will be reverted in mainline. There is a different fix available which does not have that problem, which will be marked with a Fixes tag and will be suitable for backporting. Thanks, tglx

[PATCH 1/2] accel/ivpu: Fix the NPU's DPU frequency calculation

by Maciej Falkowski

From: Andrzej Kacprowski <Andrzej.Kacprowski(a)intel.com> Fix the frequency returned to the user space by the DRM_IVPU_PARAM_CORE_CLOCK_RATE GET_PARAM IOCTL. The kernel driver returned CPU frequency for MTL and bare PLL frequency for LNL - this was inconsistent and incorrect for both platforms. With this fix the driver returns maximum frequency of the NPU data processing unit (DPU) for all HW generations. This is what user space always expected. Also do not set CPU frequency in boot params - the firmware does not use frequency passed from the driver, it was only used by the early pre-production firmware. With that we can remove CPU frequency calculation code. Show NPU frequency in FREQ_CHANGE interrupt when frequency tracking is enabled.
