From: Zhang Jianhua <chris.zjh(a)huawei.com> hulk inclusion category: bugfix bugzilla: 182892, https://gitee.com/openeuler/kernel/issues/I4F04R -------- While reboot the system by sysrq, the following bug will be occur. BUG: sleeping function called from invalid context at kernel/locking/semaphore.c:90 in_atomic(): 0, irqs_disabled(): 128, non_block: 0, pid: 10052, name: rc.shutdown CPU: 3 PID: 10052 Comm: rc.shutdown Tainted: G W O 5.10.0 #1 Call trace: dump_backtrace+0x0/0x1c8 show_stack+0x18/0x28 dump_stack+0xd0/0x110 ___might_sleep+0x14c/0x160 __might_sleep+0x74/0x88 down_interruptible+0x40/0x118 virt_efi_reset_system+0x3c/0xd0 efi_reboot+0xd4/0x11c machine_restart+0x60/0x9c emergency_restart+0x1c/0x2c sysrq_handle_reboot+0x1c/0x2c __handle_sysrq+0xd0/0x194 write_sysrq_trigger+0xbc/0xe4 proc_reg_write+0xd4/0xf0 vfs_write+0xa8/0x148 ksys_write+0x6c/0xd8 __arm64_sys_write+0x18/0x28 el0_svc_common.constprop.3+0xe4/0x16c do_el0_svc+0x1c/0x2c el0_svc+0x20/0x30 el0_sync_handler+0x80/0x17c el0_sync+0x158/0x180 The reason for this problem is that irq has been disabled in machine_restart() and then it calls down_interruptible() in virt_efi_reset_system(), which would occur sleep in irq context, it is dangerous! Commit 99409b935c9a("locking/semaphore: Add might_sleep() to down_*() family") add might_sleep() in down_interruptible(), so the bug info is here. down_trylock() can solve this problem, cause there is no might_sleep.

[PATCH kernel-4.19 1/2] fuse: truncate pagecache on atomic_o_trunc
by Yang Yingliang 22 Oct '21

22 Oct '21

From: Miklos Szeredi <mszeredi(a)redhat.com> mainline inclusion from mainline-5.14 commit 76224355db7570cbe6b6f75c8929a1558828dd55 category: bugfix bugzilla: 181107 CVE: NA --------------------------- fuse_finish_open() will be called with FUSE_NOWRITE in case of atomic O_TRUNC. This can deadlock with fuse_wait_on_page_writeback() in fuse_launder_page() triggered by invalidate_inode_pages2(). Fix by replacing invalidate_inode_pages2() in fuse_finish_open() with a truncate_pagecache() call. This makes sense regardless of FOPEN_KEEP_CACHE or fc->writeback cache, so do it unconditionally.

[PATCH kernel-4.19 1/4] ext4: check and update i_disksize properly
by Yang Yingliang 22 Oct '21

22 Oct '21

From: Zhang Yi <yi.zhang(a)huawei.com> mainline inclusion from mainline-5.15-rc4 commit 4df031ff5876d94b48dd9ee486ba5522382a06b2 category: perf bugzilla: NA CVE: NA --------------------------- After commit 3da40c7b0898 ("ext4: only call ext4_truncate when size <= isize"), i_disksize could always be updated to i_size in ext4_setattr(), and we could sure that i_disksize <= i_size since holding inode lock and if i_disksize < i_size there are delalloc writes pending in the range upto i_size. If the end of the current write is <= i_size, there's no need to touch i_disksize since writeback will push i_disksize upto i_size eventually. So we can switch to check i_size instead of i_disksize in ext4_da_write_end() when write to the end of the file. we also could remove ext4_mark_inode_dirty() together because we defer inode dirtying to generic_write_end() or ext4_da_write_inline_data_end().

[PATCH kernel-4.19] net:fix tcp timeout retransmits are always missing 2 times
by Yang Yingliang 21 Oct '21

From: jiazhenyuan <jiazhenyuan(a)uniontech.com> mainline inclusion from mainline-v5.4-rc2 commit 3256a2d6ab1f71f9a1bd2d7f6f18eb8108c48d17 category: bugfix bugzilla: https://gitee.com/openeuler/kernel/issues/I4AFRJ?from=project-issue CVE: NA --------------------------------------------------------------- tcp: adjust rto_base in retransmits_timed_out() The cited commit exposed an old retransmits_timed_out() bug which assumed it could call tcp_model_timeout() with TCP_RTO_MIN as rto_base for all states. But flows in SYN_SENT or SYN_RECV state uses a different RTO base (1 sec instead of 200 ms, unless BPF choses another value) This caused a reduction of SYN retransmits from 6 to 4 with the default /proc/sys/net/ipv4/tcp_syn_retries value.

[PATCH kernel-4.19 1/6] mm/page_alloc.c: memory hotplug: free pages as higher order
by Yang Yingliang 20 Oct '21

20 Oct '21

From: Arun KS <arunks(a)codeaurora.org> mainline inclusion from mainline-v5.1-rc1 commit a9cd410a3d296846a8125aa43d97a573a354c472 category: feature bugzilla: 182882 CVE: NA ----------------------------------------------- When freeing pages are done with higher order, time spent on coalescing pages by buddy allocator can be reduced. With section size of 256MB, hot add latency of a single section shows improvement from 50-60 ms to less than 1 ms, hence improving the hot add latency by 60 times. Modify external providers of online callback to align with the change.

[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).

hi gouhao: 这个补丁删除了hibmc_connector_init使用点，导致hibmc_connector_init函数申明但无使用点告警。同时注意到本patch部分代码在主线通过 be8c8403f63cf ("drm/hisilicon: Code refactoring for hibmc_drv_vdac") 合入，因此希望能够直接将该patch作为本patch的前向补丁一起合入。 best regard >>>>>>>>>>>>>>>>>>>>>>>>>> [WARNING] build_arm64_kabi <<<<<<<<<<<<<<<<<<<<<<<<<< make ARCH=arm64 CROSS_COMPILE=aarch64-linux-gnu- defconfig && make -j8 ARCH=arm64 CROSS_COMPILE=aarch64-linux-gnu- drivers/gpu/drm/hisilicon/hibmc/hibmc_drm_vdac.c:125:1: warning: ‘hibmc_connector_init’ defined but not used [-Wunused-function] hibmc_connector_init(struct hibmc_drm_private *priv) ^~~~~~~~~~~~~~~~~~~~ ==================================END================================== On 2021/9/18 11:11, Gou Hao wrote: > From: Tian Tao <tiantao6(a)hisilicon.com> mainline inclusion from > mainline-v5.14.0-rc7 commit a0d078d06e516184e2f575f3803935697b5e3ac6 > category: bugfix bugzilla: > https://gitee.com/openeuler/kernel/issues/I469VQCVE: NA The > modification of hibmc_vdac_init in the original patch cannot be > incorporated.

[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.
