[PATCH openEuler-1.0-LTS] HID: i2c-hid: remove I2C_HID_READ_PENDING flag to prevent lock-up

From: Nam Cao <namcao(a)linutronix.de> mainline inclusion from mainline-v6.9-rc6 commit 9c0f59e47a90c54d0153f8ddc0f80d7a36207d0e category: bugfix bugzilla: https://gitee.com/src-openeuler/kernel/issues/I9QRN6 CVE: CVE-2024-35997 Reference: https://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git/commit/?… -------------------------------- The flag I2C_HID_READ_PENDING is used to serialize I2C operations.

For instance, [kworker] tls_encrypt_done(..., err=<negative error from crypto request>) tls_err_abort(.., err) sk->sk_err = err; [task] splice_from_pipe_feed ... tls_sw_do_sendpage if (sk->sk_err) { ret = -sk->sk_err; // ret is positive splice_from_pipe_feed (continued) ret = actor(...) // ret is still positive and interpreted as bytes // written, resulting in underflow of buf->len and // sd->len, leading to huge buf->offset and bogus // addresses computed in later calls to actor() Fix all tls_err_abort() callers to pass a negative error code consistently and centralize the error-prone sign flip there, throwing in a warning to catch future misuse and uninlining the function so it really does only warn once.

[PATCH openEuler-1.0-LTS] nvmem: Fix shift-out-of-bound (UBSAN) with byte size cells
by Cai Xinchen 25 May '24

25 May '24

From: Stephen Boyd <swboyd(a)chromium.org> stable inclusion from stable-v4.19.213 commit eb0fc8e7170e61eaf65d28dee4a8baf4e86b19ca category: bugfix bugzilla: https://gitee.com/src-openeuler/kernel/issues/I9RD7J CVE: CVE-2021-47497 Reference: https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git/commit/?id… -------------------------------- commit 5d388fa01fa6eb310ac023a363a6cb216d9d8fe9 upstream. If a cell has 'nbits' equal to a multiple of BITS_PER_BYTE the logic *p &= GENMASK((cell->nbits%BITS_PER_BYTE) - 1, 0); will become undefined behavior because nbits modulo BITS_PER_BYTE is 0, and we subtract one from that making a large number that is then shifted more than the number of bits that fit into an unsigned long. UBSAN reports this problem: UBSAN: shift-out-of-bounds in drivers/nvmem/core.c:1386:8 shift exponent 64 is too large for 64-bit type 'unsigned long' CPU: 6 PID: 7 Comm: kworker/u16:0 Not tainted 5.15.0-rc3+ #9 Hardware name: Google Lazor (rev3+) with KB Backlight (DT) Workqueue: events_unbound deferred_probe_work_func Call trace: dump_backtrace+0x0/0x170 show_stack+0x24/0x30 dump_stack_lvl+0x64/0x7c dump_stack+0x18/0x38 ubsan_epilogue+0x10/0x54 __ubsan_handle_shift_out_of_bounds+0x180/0x194 __nvmem_cell_read+0x1ec/0x21c nvmem_cell_read+0x58/0x94 nvmem_cell_read_variable_common+0x4c/0xb0 nvmem_cell_read_variable_le_u32+0x40/0x100 a6xx_gpu_init+0x170/0x2f4 adreno_bind+0x174/0x284 component_bind_all+0xf0/0x264 msm_drm_bind+0x1d8/0x7a0 try_to_bring_up_master+0x164/0x1ac __component_add+0xbc/0x13c component_add+0x20/0x2c dp_display_probe+0x340/0x384 platform_probe+0xc0/0x100 really_probe+0x110/0x304 __driver_probe_device+0xb8/0x120 driver_probe_device+0x4c/0xfc __device_attach_driver+0xb0/0x128 bus_for_each_drv+0x90/0xdc __device_attach+0xc8/0x174 device_initial_probe+0x20/0x2c bus_probe_device+0x40/0xa4 deferred_probe_work_func+0x7c/0xb8 process_one_work+0x128/0x21c process_scheduled_works+0x40/0x54 worker_thread+0x1ec/0x2a8 kthread+0x138/0x158 ret_from_fork+0x10/0x20 Fix it by making sure there are any bits to mask out.

From: Nicolas Pitre <nico(a)fluxnic.net> stable inclusion from stable-v4.19.312 commit fc7dfe3d123f00e720be80b920da287810a1f37d category: bugfix bugzilla: https://gitee.com/src-openeuler/kernel/issues/I9Q994 CVE: CVE-2024-35823 Reference: https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git/commit/?id… -------------------------------- commit 1581dafaf0d34bc9c428a794a22110d7046d186d upstream. This is the same issue that was fixed for the VGA text buffer in commit 39cdb68c64d8 ("vt: fix memory overlapping when deleting chars in the buffer"). The cure is also the same i.e. replace memcpy() with memmove() due to the overlaping buffers.

[PATCH openEuler-1.0-LTS] ipv6: Fix infinite recursion in fib6_dump_done().
by Zhengchao Shao 25 May '24

25 May '24

From: Kuniyuki Iwashima <kuniyu(a)amazon.com> stable inclusion from stable-v4.19.312 commit 9472d07cd095cbd3294ac54c42f304a38fbe9bfe category: bugfix bugzilla: https://gitee.com/src-openeuler/kernel/issues/I9QG76 CVE: CVE-2024-35886 Reference: https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git/commit/?id… -------------------------------- commit d21d40605bca7bd5fc23ef03d4c1ca1f48bc2cae upstream. syzkaller reported infinite recursive calls of fib6_dump_done() during netlink socket destruction. [1] From the log, syzkaller sent an AF_UNSPEC RTM_GETROUTE message, and then the response was generated. The following recvmmsg() resumed the dump for IPv6, but the first call of inet6_dump_fib() failed at kzalloc() due to the fault injection. [0] 12:01:34 executing program 3: r0 = socket$nl_route(0x10, 0x3, 0x0) sendmsg$nl_route(r0, ... snip ...) recvmmsg(r0, ... snip ...) (fail_nth: 8) Here, fib6_dump_done() was set to nlk_sk(sk)->cb.done, and the next call of inet6_dump_fib() set it to nlk_sk(sk)->cb.args[3]. syzkaller stopped receiving the response halfway through, and finally netlink_sock_destruct() called nlk_sk(sk)->cb.done(). fib6_dump_done() calls fib6_dump_end() and nlk_sk(sk)->cb.done() if it is still not NULL. fib6_dump_end() rewrites nlk_sk(sk)->cb.done() by nlk_sk(sk)->cb.args[3], but it has the same function, not NULL, calling itself recursively and hitting the stack guard page. To avoid the issue, let's set the destructor after kzalloc().

[PATCH OLK-5.10] net: atlantic: eliminate double free in error handling logic

25 May '24

From: Igor Russkikh <irusskikh(a)marvell.com> mainline inclusion from mainline-v6.8-rc1 commit b3cb7a830a24527877b0bc900b9bd74a96aea928 category: bugfix bugzilla: https://gitee.com/src-openeuler/kernel/issues/I9Q919 CVE: CVE-2023-52664 Reference: https://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git/commit/?… -------------------------------- Driver has a logic leak in ring data allocation/free, where aq_ring_free could be called multiple times on same ring, if system is under stress and got memory allocation error. Ring pointer was used as an indicator of failure, but this is not correct since only ring data is allocated/deallocated. Ring itself is an array member. Changing ring allocation functions to return error code directly. This simplifies error handling and eliminates aq_ring_free on higher layer.

[PATCH OLK-5.10] ipv6: Fix infinite recursion in fib6_dump_done().
by Zhengchao Shao 25 May '24

25 May '24

From: Kuniyuki Iwashima <kuniyu(a)amazon.com> stable inclusion from stable-v5.10.215 commit fd307f2d91d40fa7bc55df3e2cd1253fabf8a2d6 category: bugfix bugzilla: https://gitee.com/src-openeuler/kernel/issues/I9QG76 CVE: CVE-2024-35886 Reference: https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git/commit/?id… -------------------------------- commit d21d40605bca7bd5fc23ef03d4c1ca1f48bc2cae upstream. syzkaller reported infinite recursive calls of fib6_dump_done() during netlink socket destruction. [1] From the log, syzkaller sent an AF_UNSPEC RTM_GETROUTE message, and then the response was generated. The following recvmmsg() resumed the dump for IPv6, but the first call of inet6_dump_fib() failed at kzalloc() due to the fault injection. [0] 12:01:34 executing program 3: r0 = socket$nl_route(0x10, 0x3, 0x0) sendmsg$nl_route(r0, ... snip ...) recvmmsg(r0, ... snip ...) (fail_nth: 8) Here, fib6_dump_done() was set to nlk_sk(sk)->cb.done, and the next call of inet6_dump_fib() set it to nlk_sk(sk)->cb.args[3]. syzkaller stopped receiving the response halfway through, and finally netlink_sock_destruct() called nlk_sk(sk)->cb.done(). fib6_dump_done() calls fib6_dump_end() and nlk_sk(sk)->cb.done() if it is still not NULL. fib6_dump_end() rewrites nlk_sk(sk)->cb.done() by nlk_sk(sk)->cb.args[3], but it has the same function, not NULL, calling itself recursively and hitting the stack guard page. To avoid the issue, let's set the destructor after kzalloc().

[PATCH OLK-5.10] drm/amdgpu: handle the case of pci_channel_io_frozen only in amdgpu_pci_resume
by Xiongfeng Wang 24 May '24

24 May '24

From: Guchun Chen <guchun.chen(a)amd.com> mainline inclusion from mainline-v5.15-rc5 commit 248b061689a40f4fed05252ee2c89f87cf26d7d8 category: bugfix bugzilla: https://gitee.com/src-openeuler/kernel/issues/I9R4NB CVE: CVE-2021-47421 Reference: https://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git/commit/?… -------------------------------- In current code, when a PCI error state pci_channel_io_normal is detectd, it will report PCI_ERS_RESULT_CAN_RECOVER status to PCI driver, and PCI driver will continue the execution of PCI resume callback report_resume by pci_walk_bridge, and the callback will go into amdgpu_pci_resume finally, where write lock is releasd unconditionally without acquiring such lock first. In this case, a deadlock will happen when other threads start to acquire the read lock. To fix this, add a member in amdgpu_device strucutre to cache pci_channel_state, and only continue the execution in amdgpu_pci_resume when it's pci_channel_io_frozen.

[PATCH openEuler-1.0-LTS] hwmon: (mlxreg-fan) Return non-zero value when fan current state is enforced from sysfs
by Zheng Yejian 24 May '24

24 May '24

From: Vadim Pasternak <vadimp(a)nvidia.com> stable inclusion from stable-v4.19.209 commit 5c6e0bce647d9cb32a17d58ffa669b3421fcc6ca category: bugfix bugzilla: https://gitee.com/src-openeuler/kernel/issues/I9R4O0 CVE: CVE-2021-47393 Reference: https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git/commit/?id… -------------------------------- [ Upstream commit e6fab7af6ba1bc77c78713a83876f60ca7a4a064 ] Fan speed minimum can be enforced from sysfs. For example, setting current fan speed to 20 is used to enforce fan speed to be at 100% speed, 19 - to be not below 90% speed, etcetera. This feature provides ability to limit fan speed according to some system wise considerations, like absence of some replaceable units or high system ambient temperature. Request for changing fan minimum speed is configuration request and can be set only through 'sysfs' write procedure. In this situation value of argument 'state' is above nominal fan speed maximum. Return non-zero code in this case to avoid thermal_cooling_device_stats_update() call, because in this case statistics update violates thermal statistics table range. The issues is observed in case kernel is configured with option CONFIG_THERMAL_STATISTICS. Here is the trace from KASAN: [ 159.506659] BUG: KASAN: slab-out-of-bounds in thermal_cooling_device_stats_update+0x7d/0xb0 [ 159.516016] Read of size 4 at addr ffff888116163840 by task hw-management.s/7444 [ 159.545625] Call Trace: [ 159.548366] dump_stack+0x92/0xc1 [ 159.552084] ? thermal_cooling_device_stats_update+0x7d/0xb0 [ 159.635869] thermal_zone_device_update+0x345/0x780 [ 159.688711] thermal_zone_device_set_mode+0x7d/0xc0 [ 159.694174] mlxsw_thermal_modules_init+0x48f/0x590 [mlxsw_core] [ 159.700972] ? mlxsw_thermal_set_cur_state+0x5a0/0x5a0 [mlxsw_core] [ 159.731827] mlxsw_thermal_init+0x763/0x880 [mlxsw_core] [ 160.070233] RIP: 0033:0x7fd995909970 [ 160.074239] Code: 73 01 c3 48 8b 0d 28 d5 2b 00 f7 d8 64 89 01 48 83 c8 ff c3 66 0f 1f 44 00 00 83 3d 99 2d 2c 00 00 75 10 b8 01 00 00 00 0f 05 <48> 3d 01 f0 ff ..

[PATCH openEuler-1.0-LTS] ipv6: fix race condition between ipv6_get_ifaddr and ipv6_del_addr
by Zhao Mengmeng 24 May '24

24 May '24

From: Jiri Benc <jbenc(a)redhat.com> stable inclusion from stable-v4.19.313 commit b4b3b69a19016d4e7fbdbd1dbcc184915eb862e1 category: bugfix bugzilla: https://gitee.com/src-openeuler/kernel/issues/I9QRPL CVE: CVE-2024-35969 Reference: https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git/commit/?id… -------------------------------- [ Upstream commit 7633c4da919ad51164acbf1aa322cc1a3ead6129 ] Although ipv6_get_ifaddr walks inet6_addr_lst under the RCU lock, it still means hlist_for_each_entry_rcu can return an item that got removed from the list. The memory itself of such item is not freed thanks to RCU but nothing guarantees the actual content of the memory is sane. In particular, the reference count can be zero. This can happen if ipv6_del_addr is called in parallel. ipv6_del_addr removes the entry from inet6_addr_lst (hlist_del_init_rcu(&ifp->addr_lst)) and drops all references (__in6_ifa_put(ifp) + in6_ifa_put(ifp)). With bad enough timing, this can happen: 1. In ipv6_get_ifaddr, hlist_for_each_entry_rcu returns an entry. 2. Then, the whole ipv6_del_addr is executed for the given entry. The reference count drops to zero and kfree_rcu is scheduled. 3. ipv6_get_ifaddr continues and tries to increments the reference count (in6_ifa_hold). 4.

[PATCH OLK-5.10] ipv6: fix race condition between ipv6_get_ifaddr and ipv6_del_addr
by Zhao Mengmeng 23 May '24

23 May '24

From: Jiri Benc <jbenc(a)redhat.com> stable inclusion from stable-v5.10.216 commit 3fb02ec57ead2891a2306af8c51a306bc5945e70 category: bugfix bugzilla: https://gitee.com/src-openeuler/kernel/issues/I9QRPL CVE: CVE-2024-35969 Reference: https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git/commit/?id… -------------------------------- [ Upstream commit 7633c4da919ad51164acbf1aa322cc1a3ead6129 ] Although ipv6_get_ifaddr walks inet6_addr_lst under the RCU lock, it still means hlist_for_each_entry_rcu can return an item that got removed from the list. The memory itself of such item is not freed thanks to RCU but nothing guarantees the actual content of the memory is sane. In particular, the reference count can be zero. This can happen if ipv6_del_addr is called in parallel. ipv6_del_addr removes the entry from inet6_addr_lst (hlist_del_init_rcu(&ifp->addr_lst)) and drops all references (__in6_ifa_put(ifp) + in6_ifa_put(ifp)). With bad enough timing, this can happen: 1. In ipv6_get_ifaddr, hlist_for_each_entry_rcu returns an entry. 2. Then, the whole ipv6_del_addr is executed for the given entry. The reference count drops to zero and kfree_rcu is scheduled. 3. ipv6_get_ifaddr continues and tries to increments the reference count (in6_ifa_hold). 4. The rcu is unlocked and the entry is freed. 5. The freed entry is returned. Prevent increasing of the reference count in such case. The name in6_ifa_hold_safe is chosen to mimic the existing fib6_info_hold_safe. [ 41.506330] refcount_t: addition on 0; use-after-free.

[PATCH OLK-6.6] Bluetooth: L2CAP: Fix slab-use-after-free in l2cap_connect()

Also make the l2cap_connect() return type void. Nothing is using the returned value but it is ugly to return a potentially freed pointer.

[PATCH OLK-5.10] drm/i915/gt: Reset queue_priority_hint on parking

From: Chris Wilson <chris(a)chris-wilson.co.uk> stable inclusion from stable-v5.10.216 commit fe34587acc995e7b1d7a5d3444a0736721ec32b3 category: bugfix bugzilla: https://gitee.com/src-openeuler/kernel/issues/I9L5FX CVE: CVE-2024-26937 Reference: https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git/commit/?h=… -------------------------------- commit 4a3859ea5240365d21f6053ee219bb240d520895 upstream. Originally, with strict in order execution, we could complete execution only when the queue was empty. Preempt-to-busy allows replacement of an active request that may complete before the preemption is processed by HW. If that happens, the request is retired from the queue, but the queue_priority_hint remains set, preventing direct submission until after the next CS interrupt is processed.

[PATCH OLK-6.6 v2] mm: add thp anon pmd size mapping align control
by Ze Zuo 23 May '24

23 May '24

From: Kefeng Wang <wangkefeng.wang(a)huawei.com> hulk inclusion category: feature bugzilla: https://gitee.com/openeuler/kernel/issues/I9R7N8 CVE: NA ------------------------------------------------- After committing df0ad0579ac9 ('mm: align larger anonymous mappings on THP boundaries'), we found a number of issues, eg, a significant increase in memory access latency on arm64, which was addressed by commit bb713c2a4a43 (arm64: mmap: disable align larger anonymous mappings on THP boundaries), but subsequently found on x86 that the patch also resulted in a significant degradation of the SPECCPU test. Commit 449846913eb6('mm: huge_memory: add thp mapping align control') has implemented the sysfs interface control of 64 KB aligned mapping in arm64, based on this for thp_align_mapping to add a new bit to control pmd size page alignment, where the 64K alignment mapping enable for arm64 will depend on the new bits being turned on. it is disabled by default, and could be enabled by /sys/kernel/mm/transparent_hugepage/thp_mapping_align.

by Zhang Qiao 23 May '24

23 May '24

hulk inclusion category: bugfix bugzilla: https://gitee.com/openeuler/kernel/issues/I9RMHW CVE: NA -------------------------------- When perform load balance, a NUMA imbalance is allowed if busy CPUs is less than the maximum threshold, it keeps a pair of communication tasks on the current node when the destination is lightly loaded. 1. But, calculate_imbalance() use local->sum_nr_running, it may not be accurate, because communication tasks is on busiest group, so should be busiest->sum_nr_running. 2. At the same time, idles cpus are used to calculate imbalance, but the group_weight may not be the same between local and busiest groups. In this case, even if both groups are very idle, imbalance will be calculated very large, so the imbalance is calculated by calculating the difference of busy cpus between groups.

[PATCH OLK-6.6] mm: add thp anon pmd size mapping align control

23 May '24

From: Kefeng Wang <wangkefeng.wang(a)huawei.com> hulk inclusion category: feature bugzilla: https://gitee.com/openeuler/kernel/issues/I9R7N8 CVE: NA ------------------------------------------------- After committing df0ad0579ac9 ('mm: align larger anonymous mappings on THP boundaries'), we found a number of issues, eg, a significant increase in memory access latency on arm64, which was addressed by commit bb713c2a4a43 (arm64: mmap: disable align larger anonymous mappings on THP boundaries), but subsequently found on x86 that the patch also resulted in a significant degradation of the SPECCPU test. Commit 449846913eb6('mm: huge_memory: add thp mapping align control') has implemented the sysfs interface control of 64 KB aligned mapping in arm64, based on this for thp_align_mapping to add a new bit to control pmd size page alignment, where the 64K alignment mapping enable for arm64 will depend on the new bits being turned on. it is disabled by default, and could be enabled by /sys/kernel/mm/transparent_hugepage/thp_mapping_align.

[PATCH openEuler-1.0-LTS] netfilter: nft_flow_offload: reset dst in route object after setting up flow
by Liu Jian 22 May '24

22 May '24

From: Pablo Neira Ayuso <pablo(a)netfilter.org> mainline inclusion from mainline-v6.8-rc6 commit 9e0f0430389be7696396c62f037be4bf72cf93e3 category: bugfix bugzilla: https://gitee.com/src-openeuler/kernel/issues/I9Q8LQ CVE: CVE-2024-27403 Reference: https://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git/commit/?… --------------------------- dst is transferred to the flow object, route object does not own it anymore.

[PATCH OLK-5.10] kobject: Fix global-out-of-bounds in kobject_action_type()
by Xia Fukun 22 May '24

22 May '24

hulk inclusion category: bugfix bugzilla: https://gitee.com/openeuler/kernel/issues/I9REGZ CVE: NA -------------------------------- The following c language code can trigger KASAN's global variable out-of-bounds access error in kobject_action_type(): int main() { int fd; char *filename = "/sys/block/ram12/uevent"; char str[86] = "offline"; int len = 86; fd = open(filename, O_WRONLY); if (fd == -1) { printf("open"); exit(1); } if (write(fd, str, len) == -1) { printf("write"); exit(1); } close(fd); return 0; } Function kobject_action_type() receives the input parameters buf and count, where count is the length of the string buf. In the use case we provided, count is 86, the count_first is 85. Buf points to a string with a length of 86, and its first seven characters are "offline". In line 87 of the code, kobject_actions[action] is the string "offline" with the length of 7,an out-of-boundary access will appear: kobject_actions[action][85]. Modify the judgment logic in line 87. If the length of the string kobject_actions[action] is greater than count_first(e.g. buf is "off", count is 3), continue the loop. Otherwise, the match is considered successful. This change means that our test case will be successfully parsed as an offline event and no out-of-bounds access error will occur.

[PATCH OLK-5.10] LoongArch: Define the __io_aw() hook as mmiowb()
by Hui Tang 22 May '24

22 May '24

From: Huacai Chen <chenhuacai(a)loongson.cn> mainline inclusion from mainline-v6.9-rc1 commit 9c68ece8b2a5c5ff9b2fcaea923dd73efeb174cd category: bugfix bugzilla: https://gitee.com/src-openeuler/kernel/issues/I9Q939 CVE: CVE-2024-35818 Reference: https://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git/commit/?… -------------------------------- Commit fb24ea52f78e0d595852e ("drivers: Remove explicit invocations of mmiowb()") remove all mmiowb() in drivers, but it says: "NOTE: mmiowb() has only ever guaranteed ordering in conjunction with spin_unlock(). However, pairing each mmiowb() removal in this patch with the corresponding call to spin_unlock() is not at all trivial, so there is a small chance that this change may regress any drivers incorrectly relying on mmiowb() to order MMIO writes between CPUs using lock-free synchronisation." The mmio in radeon_ring_commit() is protected by a mutex rather than a spinlock, but in the mutex fastpath it behaves similar to spinlock. We can add mmiowb() calls in the radeon driver but the maintainer says he doesn't like such a workaround, and radeon is not the only example of mutex protected mmio. So we should extend the mmiowb tracking system from spinlock to mutex, and maybe other locking primitives. This is not easy and error prone, so we solve it in the architectural code, by simply defining the __io_aw() hook as mmiowb(). And we no longer need to override queued_spin_unlock() so use the generic definition. Without this, we get such an error when run 'glxgears' on weak ordering architectures such as LoongArch: radeon 0000:04:00.0: ring 0 stalled for more than 10324msec radeon 0000:04:00.0: ring 3 stalled for more than 10240msec radeon 0000:04:00.0: GPU lockup (current fence id 0x000000000001f412 last fence id 0x000000000001f414 on ring 3) radeon 0000:04:00.0: GPU lockup (current fence id 0x000000000000f940 last fence id 0x000000000000f941 on ring 0) radeon 0000:04:00.0: scheduling IB failed (-35).

However, when the control flow returns to si_dpm_sw_init, it goes to label dpm_failed and calls si_dpm_fini, which calls amdgpu_free_extended_power_table again and free those fields again. Thus a double-free is triggered.

[PATCH OLK-5.10] netfilter: nf_tables: use timestamp to check for set element timeout
by Liu Jian 22 May '24

22 May '24

mainline inclusion from mainline-v6.8-rc4 commit 7395dfacfff65e9938ac0889dafa1ab01e987d15 category: bugfix bugzilla: https://gitee.com/src-openeuler/kernel/issues/I9O0MR CVE: CVE-2024-27397 Reference: https://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git/commit/?… --------------------------- Add a timestamp field at the beginning of the transaction, store it in the nftables per-netns area. Update set backend .insert, .deactivate and sync gc path to use the timestamp, this avoids that an element expires while control plane transaction is still unfinished. .lookup and .update, which are used from packet path, still use the current time to check if the element has expired. And .get path and dump also since this runs lockless under rcu read size lock. Then, there is async gc which also needs to check the current time since it runs asynchronously from a workqueue.

[PATCH openEuler-22.03-LTS-SP1] net/smc: reduce rtnl pressure in smc_pnet_create_pnetids_list()
by Zhengchao Shao 22 May '24

22 May '24

From: Eric Dumazet <edumazet(a)google.com> stable inclusion from stable-v5.10.215 commit bc4d1ebca11b4f194e262326bd45938e857c59d2 category: bugfix bugzilla: https://gitee.com/src-openeuler/kernel/issues/I9QGJZ CVE: CVE-2024-35934 Reference: https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git/commit/?id… -------------------------------- [ Upstream commit 00af2aa93b76b1bade471ad0d0525d4d29ca5cc0 ] Many syzbot reports show extreme rtnl pressure, and many of them hint that smc acquires rtnl in netns creation for no good reason [1] This patch returns early from smc_pnet_net_init() if there is no netdevice yet. I am not even sure why smc_pnet_create_pnetids_list() even exists, because smc_pnet_netdev_event() is also calling smc_pnet_add_base_pnetid() when handling NETDEV_UP event.

[PATCH OLK-6.6 v2 00/37] mm: Some bugfix and optimization
by Liu Shixin 22 May '24

22 May '24

Patch [1-21] is series "Rearrange batched folio freeing" and three bugfix. Patch [22-26] is series "Clean up __folio_put()". Patch [27] add trace of alloc_contig_migrate_range. Patch [28-30] is three bugfix about hugetlb. Patch [31] is an performance optimization of pcp draining. Patch [32] is a minor improve of _deferred_list which benefit from debug. This patch is from series "Various significant MM patches". Other patches are not related to this patch, so don't backport together. Patch "mm: Free up PG_slab" may also benefit for us, but have compile problem need to fix, so not in this series. Patch [33-36] is part of series "Improve anon_vma scalability for anon VMAs". Patch "mm: Fix some minor per-VMA lock issues in userfaultfd" is not in backport because it depends on patch "userfaultfd: use per-vma locks in userfaultfd operations" Patch [37] fix a bug introduced by patch "mm: turn folio_test_hugetlb into a PageType" which is from the previous backport. v1->v2: Add patch [37].

[PATCH OLK-5.10] netfilter: nf_tables: discard table flag update with pending basechain deletion
by Liu Jian 22 May '24

22 May '24

From: Pablo Neira Ayuso <pablo(a)netfilter.org> stable inclusion from stable-v5.10.215 commit b58d0ac35f6d75ec1db8650a29dfd6f292c11362 category: bugfix bugzilla: https://gitee.com/src-openeuler/kernel/issues/I9QG9F CVE: CVE-2024-35897 Reference: https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git/commit/?id… --------------------------- commit 1bc83a019bbe268be3526406245ec28c2458a518 upstream. Hook unregistration is deferred to the commit phase, same occurs with hook updates triggered by the table dormant flag. When both commands are combined, this results in deleting a basechain while leaving its hook still registered in the core.
