[PATCH OLK-6.6 v4 00/39] High Performance Container Resource View Isolation -- Stage 2
by GONG Ruiqi 01 Aug '25

01 Aug '25

v4: - Fix compile failure of bpf_mem_failure() when CONFIG_MEMORY_FAILURE=n - Move iterator target for diskstats & partitions into block/bpf-rvi.c, to avoid unexpected "kABI changes" (actually no) v3: - Optimize swaptotal's estimation and make it a stand-alone function v2: - Remove pidns's refcount from the loadavg global list. - Optimize calculation of swap{total,usage,free} for swap and meminfo - Fix a put_task_struct() missing for bpf_disk_seqf_start() - Remove ineffective build control in samples/bpf/Makefile - Clean up some commented code --- Common supports: bpf-rvi: cpuset: Fix missing of

[PATCH OLK-5.10] net_sched: sch_sfq: don't allow 1 packet limit
by Wang Liang 01 Aug '25

01 Aug '25

From: Octavian Purdila <tavip(a)google.com> mainline inclusion from mainline-v6.14-rc1 commit 10685681bafce6febb39770f3387621bf5d67d0b category: bugfix bugzilla: https://gitee.com/src-openeuler/kernel/issues/IBVH45 CVE: CVE-2024-57996 Reference: https://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git/commit/?… -------------------------------- The current implementation does not work correctly with a limit of 1. iproute2 actually checks for this and this patch adds the check in kernel as well.

TBF is out of tokens so it schedules itself for later. * the second packet is sent and TBF tries to queues it to SFQ. qdisc qlen is now 2 and because the SFQ limit is 1 the packet is dropped by SFQ. At this point qlen is 1, and all of the SFQ slots are empty, however q->tail is not NULL. At this point, assuming no more packets are queued, when sch_dequeue runs again it will decrement the qlen for the current empty slot causing an underflow and the subsequent out of bounds access.

[PATCH OLK-5.10] net/sched: act_ct: fix ref leak when switching zones
by Wang Liang 01 Aug '25

01 Aug '25

From: Marcelo Ricardo Leitner <marcelo.leitner(a)gmail.com> mainline inclusion from mainline-v5.18-rc1 commit bcb74e132a76ce0502bb33d5b65533a4ed72d159 category: bugfix bugzilla: https://gitee.com/src-openeuler/kernel/issues/IBP2JY CVE: CVE-2022-49183 Reference: https://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git/commit/?… -------------------------------- When switching zones or network namespaces without doing a ct clear in between, it is now leaking a reference to the old ct entry. That's because tcf_ct_skb_nfct_cached() returns false and tcf_ct_flow_table_lookup() may simply overwrite it. The fix is to, as the ct entry is not reusable, free it already at tcf_ct_skb_nfct_cached().
