[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. Reset dst in route object, otherwise if flow_offload_add() fails, error path releases dst twice, leading to a refcount underflow.

[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.
