[PATCH openEuler-22.03-LTS-SP1] nvme-fabrics: use reserved tag for reg read/write command
by Guo Mengqi 27 Aug '24

27 Aug '24

From: Chunguang Xu <chunguang.xu(a)shopee.com> mainline inclusion from mainline-v6.10-rc3 commit 7dc3bfcb4c9cc58970fff6aaa48172cb224d85aa category: bugfix bugzilla: https://gitee.com/src-openeuler/kernel/issues/IAGEKB CVE: CVE-2024-41082 Reference: https://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git/commit/?… -------------------------------- In some scenarios, if too many commands are issued by nvme command in the same time by user tasks, this may exhaust all tags of admin_q. If a reset (nvme reset or IO timeout) occurs before these commands finish, reconnect routine may fail to update nvme regs due to insufficient tags, which will cause kernel hang forever. In order to workaround this issue, maybe we can let reg_read32()/reg_read64()/reg_write32() use reserved tags. This maybe safe for nvmf: 1. For the disable ctrl path, we will not issue connect command 2. For the enable ctrl / fw activate path, since connect and reg_xx() are called serially. So the reserved tags may still be enough while reg_xx() use reserved tags.

[PATCH openEuler-1.0-LTS] net/ipv6: Fix the RT cache flush via sysctl using a previous delay

From: Petr Pavlu <petr.pavlu(a)suse.com> stable inclusion from stable-v4.19.317 commit ebde6e8a52c68dc45b4ae354e279ba74788579e7 category: bugfix bugzilla: https://gitee.com/openeuler/kernel/issues/IAMPH5 Reference: https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git/commit/?id… ------------------------------------------------- [ Upstream commit 14a20e5b4ad998793c5f43b0330d9e1388446cf3 ] The net.ipv6.route.flush system parameter takes a value which specifies a delay used during the flush operation for aging exception routes. The written value is however not used in the currently requested flush and instead utilized only in the next one. A problem is that ipv6_sysctl_rtcache_flush() first reads the old value of net->ipv6.sysctl.flush_delay into a local delay variable and then calls proc_dointvec() which actually updates the sysctl based on the provided input. Fix the problem by switching the order of the two operations. Fixes: 4990509f19e8 ("[NETNS][IPV6]: Make sysctls route per namespace.")

From: Eric Dumazet <edumazet(a)google.com> stable inclusion from stable-v4.19.317 commit 06f208ae0670ef97b0bf253a5523863e113026b6 category: bugfix bugzilla: https://gitee.com/src-openeuler/kernel/issues/IAMPH5 Reference: https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git/commit/?id… --------------------------- [ Upstream commit d37fe4255abe8e7b419b90c5847e8ec2b8debb08 ] tcp_v6_syn_recv_sock() calls ip6_dst_store() before inet_sk(newsk)->pinet6 has been set up. This means ip6_dst_store() writes over the parent (listener) np->dst_cookie. This is racy because multiple threads could share the same parent and their final np->dst_cookie could be wrong. Move ip6_dst_store() call after inet_sk(newsk)->pinet6 has been changed and after the copy of parent ipv6_pinfo.

From: Zijun Hu <quic_zijuhu(a)quicinc.com> mainline inclusion from mainline-v6.11-rc1 commit dd6e9894b451e7c85cceb8e9dc5432679a70e7dc category: bugfix bugzilla: https://gitee.com/src-openeuler/kernel/issues/IAKPXP CVE: CVE-2024-42292 Reference: https://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git/commit/?… -------------------------------- zap_modalias_env() wrongly calculates size of memory block to move, so will cause OOB memory access issue if variable MODALIAS is not the last one within its @env parameter, fixed by correcting size to memmove.
