[PATCH openEuler-5.10] ARM: spectre-v2: turn off the mitigation via boot cmdline param
by Zheng Zengkai 19 Oct '21

19 Oct '21

From: "GONG, Ruiqi" <gongruiqi1(a)huawei.com> hulk inclusion category: feature feature: switch of spectre mitigation bugzilla: 180851 https://gitee.com/openeuler/kernel/issues/I4EF1O ------------------------------------------------- We enable spectre mitigation by default for ARM32, which may cause performance regression. To offer an option to turn off this feature, implement a cmdline parameter 'nospectre_v2' compatible with mainline, which sets up a switch to skip invalidating BTB/icache for A9/A15 in context switching and user abort.

[PATCH openEuler-5.10 1/2] sched/rt: Fix double enqueue caused by rt_effective_prio
by Zheng Zengkai 19 Oct '21

19 Oct '21

From: Peter Zijlstra <peterz(a)infradead.org> stable inclusion from stable-5.10.58 commit a3e6bd0c71bb5e4821aff9ab8f221bfc08039d73 bugzilla: 176984 https://gitee.com/openeuler/kernel/issues/I4E2P4 Reference: https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git/commit/?id… -------------------------------- commit f558c2b834ec27e75d37b1c860c139e7b7c3a8e4 upstream. Double enqueues in rt runqueues (list) have been reported while running a simple test that spawns a number of threads doing a short sleep/run pattern while being concurrently setscheduled between rt and fair class. WARNING: CPU: 3 PID: 2825 at kernel/sched/rt.c:1294 enqueue_task_rt+0x355/0x360 CPU: 3 PID: 2825 Comm: setsched__13 RIP: 0010:enqueue_task_rt+0x355/0x360 Call Trace: __sched_setscheduler+0x581/0x9d0 _sched_setscheduler+0x63/0xa0 do_sched_setscheduler+0xa0/0x150 __x64_sys_sched_setscheduler+0x1a/0x30 do_syscall_64+0x33/0x40 entry_SYSCALL_64_after_hwframe+0x44/0xae list_add double add: new=ffff9867cb629b40, prev=ffff9867cb629b40, next=ffff98679fc67ca0. kernel BUG at lib/list_debug.c:31! invalid opcode: 0000 [#1] PREEMPT_RT SMP PTI CPU: 3 PID: 2825 Comm: setsched__13 RIP: 0010:__list_add_valid+0x41/0x50 Call Trace: enqueue_task_rt+0x291/0x360 __sched_setscheduler+0x581/0x9d0 _sched_setscheduler+0x63/0xa0 do_sched_setscheduler+0xa0/0x150 __x64_sys_sched_setscheduler+0x1a/0x30 do_syscall_64+0x33/0x40 entry_SYSCALL_64_after_hwframe+0x44/0xae __sched_setscheduler() uses rt_effective_prio() to handle proper queuing of priority boosted tasks that are setscheduled while being boosted. rt_effective_prio() is however called twice per each __sched_setscheduler() call: first directly by __sched_setscheduler() before dequeuing the task and then by __setscheduler() to actually do the priority change. If the priority of the pi_top_task is concurrently being changed however, it might happen that the two calls return different results. If, for example, the first call returned the same rt priority the task was running at and the second one a fair priority, the task won't be removed by the rt list (on_list still set) and then enqueued in the fair runqueue. When eventually setscheduled back to rt it will be seen as enqueued already and the WARNING/BUG be issued. Fix this by calling rt_effective_prio() only once and then reusing the return value. While at it refactor code as well for clarity. Concurrent priority inheritance handling is still safe and will eventually converge to a new state by following the inheritance chain(s).

[PATCH openEuler-1.0-LTS] soc: aspeed: lpc-ctrl: Fix boundary check for mmap
by Yang Yingliang 18 Oct '21

18 Oct '21

From: Iwona Winiarska <iwona.winiarska(a)intel.com> stable inclusion from linux-4.19.207 commit 9c8891b638319ddba9cfa330247922cd960c95b0 CVE: CVE-2021-42252 -------------------------------- commit b49a0e69a7b1a68c8d3f64097d06dabb770fec96 upstream. The check mixes pages (vm_pgoff) with bytes (vm_start, vm_end) on one side of the comparison, and uses resource address (rather than just the resource size) on the other side of the comparison. This can allow malicious userspace to easily bypass the boundary check and map pages that are located outside memory-region reserved by the driver.

[PATCH openEuler-1.0-LTS 1/2] mmap: userswap: fix memory leak in do_mmap
by Yang Yingliang 18 Oct '21

18 Oct '21

From: Xiongfeng Wang <wangxiongfeng2(a)huawei.com> hulk inclusion category: bugfix bugzilla: https://gitee.com/openeuler/kernel/issues/I4AHP2 CVE: NA ------------------------------------------------- When userswap is enabled, the memory pointed by 'pages' is not freed in abnormal branch in do_mmap(). To fix the issue and keep do_mmap() mostly unchanged, we rename do_mmap() to __do_mmap() and extract the memory alloc and free code out of __do_mmap(). When __do_mmap() returns a error value, we goto the error label to free the memory.

From: Desmond Cheong Zhi Xi <desmondcheongzx(a)gmail.com> stable inclusion from stable-v5.10.44 commit aa8591a58cbd2986090709e4202881f18e8ae30e bugzilla:https://bugzilla.openeuler.org/show_bug.cgi?id=435 CVE: NA ------------------------------------------------- commit c336a5ee984708db4826ef9e47d184e638e29717 upstream. This patch eliminates the following smatch warning: drivers/gpu/drm/drm_auth.c:320 drm_master_release() warn: unlocked access 'master' (line 318) expected lock '&dev->master_mutex' The 'file_priv->master' field should be protected by the mutex lock to '&dev->master_mutex'. This is because other processes can concurrently modify this field and free the current 'file_priv->master' pointer. This could result in a use-after-free error when 'master' is dereferenced in subsequent function calls to 'drm_legacy_lock_master_cleanup()' or to 'drm_lease_revoke()'. An example of a scenario that would produce this error can be seen from a similar bug in 'drm_getunique()' that was reported by Syzbot: https://syzkaller.appspot.com/bug?id=148d2f1dfac64af52ffd27b661981a540724f8… In the Syzbot report, another process concurrently acquired the device's master mutex in 'drm_setmaster_ioctl()', then overwrote 'fpriv->master' in 'drm_new_set_master()'. The old value of 'fpriv->master' was subsequently freed before the mutex was unlocked.
