[PATCH OLK-5.10] media: v4l2-tpg: prevent the risk of a division by zero

From: Mauro Carvalho Chehab <mchehab+huawei(a)kernel.org> stable inclusion from stable-v5.10.230 commit 054931ca3cfcb8e8fa036e887d6f379942b02565 category: bugfix bugzilla: https://gitee.com/src-openeuler/kernel/issues/IB5ATB CVE: CVE-2024-50287 Reference: https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git/commit/?h=… -------------------------------- media: v4l2-tpg: prevent the risk of a division by zero commit e6a3ea83fbe15d4818d01804e904cbb0e64e543b upstream. As reported by Coverity, the logic at tpg_precalculate_line() blindly rescales the buffer even when scaled_witdh is equal to zero. If this ever happens, this will cause a division by zero. Instead, add a WARN_ON_ONCE() to trigger such cases and return without doing any precalculation.

[PATCH OLK-5.10] x86/sgx: Fix deadlock in SGX NUMA node search
by Zhao Yipeng 26 Dec '24

26 Dec '24

From: Aaron Lu <aaron.lu(a)intel.com> mainline inclusion from mainline-v6.12-rc1 commit 9c936844010466535bd46ea4ce4656ef17653644 category: bugfix bugzilla: https://gitee.com/src-openeuler/kernel/issues/IAYQRL CVE: CVE-2024-49856 Reference: https://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git/commit/?… -------------------------------- x86/sgx: Fix deadlock in SGX NUMA node search When the current node doesn't have an EPC section configured by firmware and all other EPC sections are used up, CPU can get stuck inside the while loop that looks for an available EPC page from remote nodes indefinitely, leading to a soft lockup. Note how nid_of_current will never be equal to nid in that while loop because nid_of_current is not set in sgx_numa_mask. Also worth mentioning is that it's perfectly fine for the firmware not to setup an EPC section on a node. While setting up an EPC section on each node can enhance performance, it is not a requirement for functionality. Rework the loop to start and end on *a* node that has SGX memory. This avoids the deadlock looking for the current SGX-lacking node to show up in the loop when it never will.

[PATCH OLK-5.10] printk: Fix the qspinlock deadloop caused by zap_locks()
by Li Huafei 26 Dec '24

26 Dec '24

hulk inclusion category: bugfix bugzilla: https://gitee.com/openeuler/kernel/issues/IBC1RM CVE: NA -------------------------------- printk calls zap_locks() to bypass logbuf_lock during panic. If the current system uses qspinlock, it may cause a deadloop in queued_spin_lock_slowpath(). Consider the following locking sequence: cpu1: (0, 0, 1) cpu2: (0, 1, 1) cpu3: (3, 1, 1) If zap_locks() is called at this time, cpu2 may acquire the lock first, and then cpu3 acquires the lock. When cpu3 releases the lock, it checks if the tail is itself. Originally, it should be, but after zap_locks(), the tail is modified to 0. At this point, cpu3 thinks there are other contenders, it will first set the locked bit and then wait for the contender to set its next pointer. However, in reality, there are no other contenders, so cpu3 will hold the lock (locked bit is 1) and loop here, causing other CPUs that want to acquire the lock to be stuck. To fix this problem, the lock initialization in zap_locks() can be degraded to clear locked_pending and retain the tail, avoiding misjudgment.
