[PATCH OLK-6.6] ext4: default enable iomap for buffered IO and large folio
by Zhang Yi 22 May '24

22 May '24

hulk inclusion category: feature bugzilla: https://gitee.com/openeuler/kernel/issues/I9PXA8 CVE: NA -------------------------------- Enable iomap path for buffered IO and large folio on 4k pagesize by default, and allow switching iomap path and buffered_head path through remount. The path switch doesn't take effect until the activing inodes destroyed.

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.
