[PATCH openEuler-5.10 01/50] inet: fully convert sk->sk_rx_dst to RCU rules
by Zheng Zengkai 31 May '22

31 May '22

From: Eric Dumazet <edumazet(a)google.com> mainline inclusion from mainline-v5.16-rc7 commit 8f905c0e7354ef261360fb7535ea079b1082c105 category: bugfix bugzilla: 186714 https://gitee.com/src-openeuler/kernel/issues/I57QUK -------------------------------- syzbot reported various issues around early demux, one being included in this changelog [1] sk->sk_rx_dst is using RCU protection without clearly documenting it. And following sequences in tcp_v4_do_rcv()/tcp_v6_do_rcv() are not following standard RCU rules. [a] dst_release(dst); [b] sk->sk_rx_dst = NULL; They look wrong because a delete operation of RCU protected pointer is supposed to clear the pointer before the call_rcu()/synchronize_rcu() guarding actual memory freeing. In some cases indeed, dst could be freed before [b] is done. We could cheat by clearing sk_rx_dst before calling dst_release(), but this seems the right time to stick to standard RCU annotations and debugging facilities.

[PATCH openEuler-5.10 1/6] slub: add back check for free nonslab objects
by Zheng Zengkai 28 May '22

28 May '22

From: Kefeng Wang <wangkefeng.wang(a)huawei.com> mainline inclusion from mainline-v5.16-rc1 commit d0fe47c64152a63ceed4b9f29ac56371407fa7b4 category: bugfix bugzilla: https://gitee.com/openeuler/kernel/issues/I57LS2 CVE: NA backport: openEuler-22.03-LTS -------------------------------- After commit f227f0faf63b ("slub: fix unreclaimable slab stat for bulk free"), the check for free nonslab page is replaced by VM_BUG_ON_PAGE, which only check with CONFIG_DEBUG_VM enabled, but this config may impact performance, so it only for debug. Commit 0937502af7c9 ("slub: Add check for kfree() of non slab objects.") add the ability, which should be needed in any configs to catch the invalid free, they even could be potential issue, eg, memory corruption, use after free and double free, so replace VM_BUG_ON_PAGE to WARN_ON_ONCE, add object address printing to help use to debug the issue.

[PATCH openEuler-5.10 v2 1/4] ipv6: per-netns exclusive flowlabel checks

28 May '22

From: Willem de Bruijn <willemb(a)google.com> stable inclusion from stable-v5.10.102 commit 4f523f15e5d753ac055302bc29ca9677d6692eed bugzilla: https://gitee.com/openeuler/kernel/issues/I575QT Reference: https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git/commit/?id… -------------------------------- commit 0b0dff5b3b98c5c7ce848151df9da0b3cdf0cc8b upstream. Ipv6 flowlabels historically require a reservation before use. Optionally in exclusive mode (e.g., user-private). Commit 59c820b2317f ("ipv6: elide flowlabel check if no exclusive leases exist") introduced a fastpath that avoids this check when no exclusive leases exist in the system, and thus any flowlabel use will be granted. That allows skipping the control operation to reserve a flowlabel entirely. Though with a warning if the fast path fails: This is an optimization. Robust applications still have to revert to requesting leases if the fast path fails due to an exclusive lease. Still, this is subtle. Better isolate network namespaces from each other. Flowlabels are per-netns. Also record per-netns whether exclusive leases are in use. Then behavior does not change based on activity in other netns.
