[PATCH OLK-5.10] net/sched: act_mirred: don't override retval if we already lost the skb
by Zhengchao Shao 13 Apr '24

From: Jakub Kicinski <kuba(a)kernel.org> mainline inclusion from mainline-v6.8-rc6 commit 166c2c8a6a4dc2e4ceba9e10cfe81c3e469e3210 category: bugfix bugzilla: https://gitee.com/src-openeuler/kernel/issues/I9E2LZ CVE: CVE-2024-26739 Reference: https://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git/commit/?… -------------------------------- If we're redirecting the skb, and haven't called tcf_mirred_forward(), yet, we need to tell the core to drop the skb by setting the retcode to SHOT. If we have called tcf_mirred_forward(), however, the skb is out of our hands and returning SHOT will lead to UaF. Move the retval override to the error path which actually need it.

[PATCH OLK-6.6 0/2] mm: batch mm counter updating in filemap_map_pages()
by Peng Zhang 13 Apr '24

13 Apr '24

From: ZhangPeng <zhangpeng362(a)huawei.com> Like copy_pte_range()/zap_pte_range(), make mm counter batch updating in filemap_map_pages(), since folios type are same(MM_SHMEMPAGES or MM_FILEPAGES) in filemap_map_pages(), only check the first folio type is enough, the 'lat_pagefault -P 1 file' test from lmbench shows 12% improvement, and the percpu_counter_add_batch() is gone from perf flame graph.
