During iscsi_tcp host and session removal we can remove the session from sysfs then remove the host from sysfs. At this point we know userspace is not accessing the kernel via sysfs so we can free the session and host.

Handle this gracefully. The best option would be unregistering the MPLS from the device completely on failure, but unfortunately mpls_ifdown() can fail. So failing fully is also unreliable. Another option is to register the new table first then only remove old one if the new one succeeds. That requires more code, changes order of notifications and two tables may be visible at the same time. sysctl point is not used in the rest of the code - set to NULL on failures and skip unregister if already NULL.

[PATCH openEuler-1.0-LTS] mm/sharepool: Fix null-pointer-deference in sp_free_area
by Yongqiang Liu 22 Feb '23

22 Feb '23

From: Wang Wensheng <wangwensheng4(a)huawei.com> hulk inclusion category: bugfix bugzilla: https://gitee.com/openeuler/kernel/issues/I6G76L CVE: NA ---------------------------------------------- When a process is deleted from a group, the process does not apply for memory from the shared group. Otherwise, the UAF problem occurs. We checked this, but it didn't do a good job of preventing sp_alloc and del_task concurrency. The process applies for memory after passing the check, which violates our requirements and causes problems. The solution is to place the checked code in the critical area to ensure that no memory can be allocated after the check is passed.

From: Liu Shixin <liushixin2(a)huawei.com> hulk inclusion category: bugfix bugzilla: https://gitee.com/openeuler/kernel/issues/I6AXGS CVE: NA -------------------------------- syzbot is reporting GFP_KERNEL allocation with oom_lock held when reporting memcg OOM [1]. If this allocation triggers the global OOM situation then the system can livelock because the GFP_KERNEL allocation with oom_lock held cannot trigger the global OOM killer because __alloc_pages_may_oom() fails to hold oom_lock. The problem mentioned above has been fixed by patch[2]. The is the same problem in memcg_memfs_info feature too. Refer to the patch[2], fix it by removing the allocation from mem_cgroup_print_memfs_info() completely, and pass static buffer when calling from memcg OOM path.

[PATCH openEuler-1.0-LTS 1/2] net: bridge: mcast: add and enforce startup query interval minimum

From: Nikolay Aleksandrov <nikolay(a)nvidia.com> mainline inclusion from mainline-v5.16-rc8 commit f83a112bd91a494cdee671aec74e777470fb4a07 category: bugfix bugzilla: https://gitee.com/openeuler/kernel/issues/I6DKZJ CVE: NA Reference: https://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git/commit/?… -------------------------------- As reported[1] if startup query interval is set too low in combination with large number of startup queries and we have multiple bridges or even a single bridge with multiple querier vlans configured we can crash the machine. Add a 1 second minimum which must be enforced by overwriting the value if set lower (i.e. without returning an error) to avoid breaking user-space. If that happens a log message is emitted to let the admin know that the startup interval has been set to the minimum. It doesn't make sense to make the startup interval lower than the normal query interval so use the same value of 1 second. The issue has been present since these intervals could be user-controlled.

[PATCH openEuler-1.0-LTS] media: vivid: fix compose size exceed boundary

[PATCH openEuler-5.10-LTS-SP1 01/87] NFSD: Fix verifier returned in stable WRITEs
by Jialin Zhang 13 Feb '23

13 Feb '23

From: Chuck Lever <chuck.lever(a)oracle.com> stable inclusion from stable-v5.10.143 commit d3d885507b52b28f54770a42d650251876d433a3 category: bugfix bugzilla: https://gitee.com/openeuler/kernel/issues/I6D0U6 Reference: https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git/commit/?id… -------------------------------- commit f11ad7aa653130b71e2e89bed207f387718216d5 upstream. RFC 8881 explains the purpose of the write verifier this way: > The final portion of the result is the field writeverf. This field > is the write verifier and is a cookie that the client can use to > determine whether a server has changed instance state (e.g., server > restart) between a call to WRITE and a subsequent call to either > WRITE or COMMIT. But then it says: > This cookie MUST be unchanged during a single instance of the > NFSv4.1 server and MUST be unique between instances of the NFSv4.1 > server. If the cookie changes, then the client MUST assume that > any data written with an UNSTABLE4 value for committed and an old > writeverf in the reply has been lost and will need to be > recovered. RFC 1813 has similar language for NFSv3. NFSv2 does not have a write verifier since it doesn't implement the COMMIT procedure. Since commit 19e0663ff9bc ("nfsd: Ensure sampling of the write verifier is atomic with the write"), the Linux NFS server has returned a boot-time-based verifier for UNSTABLE WRITEs, but a zero verifier for FILE_SYNC and DATA_SYNC WRITEs. FILE_SYNC and DATA_SYNC WRITEs are not followed up with a COMMIT, so there's no need for clients to compare verifiers for stable writes. However, by returning a different verifier for stable and unstable writes, the above commit puts the Linux NFS server a step farther out of compliance with the first MUST above. At least one NFS client (FreeBSD) noticed the difference, making this a potential regression. [Removed down_write to fix the conflict in the cherry-pick. The down_write functionality was no longer needed there. Upstream commit 555dbf1a9aac6d3150c8b52fa35f768a692f4eeb titled nfsd: Replace use of rwsem with errseq_t removed those and replace it with new functionality that was more scalable. This commit is already backported onto 5.10 and so removing down_write ensures consistency with that change. Tested by compiling and booting successfully. - kochera] Reported-by: Rick Macklem <rmacklem(a)uoguelph.ca> Link: https://lore.kernel.org/linux-nfs/YQXPR0101MB096857EEACF04A6DF1FC6D9BDD749@… Fixes: 19e0663ff9bc ("nfsd: Ensure sampling of the write verifier is atomic with the write") Signed-off-by: Chuck Lever <chuck.lever(a)oracle.com> Signed-off-by: Michael Kochera <kochera(a)google.com> Signed-off-by: Greg Kroah-Hartman <gregkh(a)linuxfoundation.org> Signed-off-by: Jialin Zhang <zhangjialin11(a)huawei.com> Reviewed-by: Zheng Zengkai <zhengzengkai(a)huawei.com> --- fs/nfsd/vfs.c | 4 ++++ 1 file changed, 4 insertions(+) diff --git a/fs/nfsd/vfs.c b/fs/nfsd/vfs.c index c852bb5ff212..a4ae1fcd2ab1 100644 --- a/fs/nfsd/vfs.c +++ b/fs/nfsd/vfs.c @@ -1014,6 +1014,10 @@ nfsd_vfs_write(struct svc_rqst *rqstp, struct svc_fh *fhp, struct nfsd_file *nf, iov_iter_kvec(&iter, WRITE, vec, vlen, *cnt); since = READ_ONCE(file->f_wb_err); if (flags & RWF_SYNC) { + if (verf) + nfsd_copy_boot_verifier(verf, + net_generic(SVC_NET(rqstp), + nfsd_net_id)); host_err = vfs_iter_write(file, &iter, &pos, flags); if (host_err < 0) nfsd_reset_boot_verifier(net_generic(SVC_NET(rqstp), -- 2.25.1

From: Yipeng Zou <zouyipeng(a)huawei.com> hulk inclusion category: feature bugzilla: https://gitee.com/openeuler/kernel/issues/I6BO2R CVE: NA -------------------------------- Now, There is some issues about LPI migration on ARM SMP platform. For example, NIC device generates MSI and sends LPI to CPU0 via ITS, meanwhile irqbalance running on CPU1 set irq affinty of NIC to CPU1, the next interrupt will be sent to CPU2, due to the state of irq is still in progress, kernel does not end up performing irq handler on CPU2, which results in some userland service timeouts, the sequence of events is shown as follows: NIC CPU0 CPU1 Generate IRQ#1 READ_IAR Lock irq_desc Set IRQD_IN_PROGRESS Unlock irq_desc Lock irq_desc Change LPI Affinity Unlock irq_desc Call irq_handler Generate IRQ#2 READ_IAR Lock irq_desc Check IRQD_IN_PROGRESS Unlock irq_desc Return from interrupt#2 Lock irq_desc Clear IRQD_IN_PROGRESS Unlock irq_desc return from interrupt#1 For this scenario, We can enable CONFIG_GENERIC_PENDING_IRQ to avoid this. The CONFIG_GENERIC_PENDING_IRQ will delay all action that modify LPI affinity until the next interrupt eoi handler.

T1 is added into journal->j_checkpoint_transactions. 3. Get bh prepare to write while doing checkpoing: PA PB do_get_write_access jbd2_log_do_checkpoint spin_lock(&jh->b_state_lock) if (buffer_dirty(bh)) clear_buffer_dirty(bh) // clear buffer dirty set_buffer_jbddirty(bh) transaction = journal->j_checkpoint_transactions jh = transaction->t_checkpoint_list if (!buffer_dirty(bh)) __jbd2_journal_remove_checkpoint(jh) // bh won't be flushed jbd2_cleanup_journal_tail __jbd2_journal_file_buffer(jh, transaction, BJ_Reserved) 4. Aborting journal/Power-cut before writing latest bh on journal area. In this way we get a corrupted filesystem with bh's data lost. Fix it by moving the clearing of buffer_dirty bit just before the call to __jbd2_journal_file_buffer(), both bit clearing and jh->b_transaction assignment are under journal->j_list_lock locked, so that jbd2_log_do_checkpoint() will wait until jh's new transaction fininshed even bh is currently not dirty. And journal_shrink_one_cp_list() won't remove jh from checkpoint list if the buffer head is reused in do_get_write_access(). Fetch a reproducer in [Link].

This makes stacktrace on the 'pop' insn fail and incorrect stacktrace result can be returned. To prevent reliable stacktrace broken, check the insns when unwind pt_regs stack frame: When there are 'push;pop' combination and both insns don't change orc entry, it means the stack state is inconsistent with orc on pop.

Due to the fact this requirement was added at the same time we added new rmap/reflink intents, we missed the cleanup of those items. In theory, this means shadow buffers can be leaked in a very small window when a shutdown is initiated. Testing with KASAN shows this leak does not happen in practice - we haven't identified a single leak in several years of shutdown testing since ~v4.8 kernels. However, the intent whiteout cleanup mechanism results in every cancelled intent in exactly the same state as this tiny race window creates and so if intents down clean up shadow buffers on final release we will leak the shadow buffer for just about every intent we create.

[PATCH openEuler-5.10-LTS-SP1 01/20] xfs: fix potential log item leak
by Jialin Zhang 07 Feb '23

07 Feb '23

From: Dave Chinner <dchinner(a)redhat.com> mainline inclusion from mainline-v5.19-rc1 commit c230a4a85bcdbfc1a7415deec6caf04e8fca1301 category: bugfix bugzilla: 187372, https://gitee.com/openeuler/kernel/issues/I5K0OM CVE: NA Reference: https://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git/commit/?… -------------------------------- Ever since we added shadown format buffers to the log items, log items need to handle the item being released with shadow buffers attached. Due to the fact this requirement was added at the same time we added new rmap/reflink intents, we missed the cleanup of those items. In theory, this means shadow buffers can be leaked in a very small window when a shutdown is initiated. Testing with KASAN shows this leak does not happen in practice - we haven't identified a single leak in several years of shutdown testing since ~v4.8 kernels. However, the intent whiteout cleanup mechanism results in every cancelled intent in exactly the same state as this tiny race window creates and so if intents down clean up shadow buffers on final release we will leak the shadow buffer for just about every intent we create. Hence we start with this patch to close this condition off and ensure that when whiteouts start to be used we don't leak lots of memory.

From: Trond Myklebust <trond.myklebust(a)hammerspace.com> mainline inclusion from mainline-v5.11-rc1 commit 9ed5af268e88f6e5b65376be98d652b37cb20d7b bugzilla: https://gitee.com/openeuler/kernel/issues/I6D0MJ Reference: https://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git/commit/?… -------------------------------- rpc_prepare_reply_pages() currently expects the 'hdrsize' argument to contain the length of the data that we expect to want placed in the head kvec plus a count of 1 word of padding that is placed after the page data. This is very confusing when trying to read the code, and sometimes leads to callers adding an arbitrary value of '1' just in order to satisfy the requirement (whether or not the page data actually needs such padding). This patch aims to clarify the code by changing the 'hdrsize' argument to remove that 1 word of padding. This means we need to subtract the padding from all the existing callers.

[PATCH OLK-5.10] net: hns3: add support handling tx dhcp packets for ROH
by Ke Chen 06 Feb '23

06 Feb '23

driver inclusion category: feature bugzilla: https://gitee.com/openeuler/kernel/issues/I6BSMN ----------------------------------------------------------------------- For ROH distributed scenario, EID is allocated by DHCP mode. Driver needs to convert the origin MAC address to EID format, and updates the destination MAC, chaddr and client id(if exists) when transmit DHCP packets. Meantime, the chaddr field should follow the source mac address, in order to make the dhcp server reply to the right client. For the payload of dhcp packet changed, so the checksum of L4 should be calculated too.

[OLK-5.10 v2 1/3] net: Use u64_stats_fetch_begin_irq() for stats fetch.
by Wang Yufen 06 Feb '23

06 Feb '23

From: Sebastian Andrzej Siewior <bigeasy(a)linutronix.de> stable inclusion from stable-v5.10.142 commit d71a1c9fce184718d1b3a51a9e8a6e31cbbb45ce category: bugfix bugzilla: https://gitee.com/openeuler/kernel/issues/I6D0ZE Reference: https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git/commit/?id… ------------------------------------------------- commit 278d3ba61563ceed3cb248383ced19e14ec7bc1f upstream. On 32bit-UP u64_stats_fetch_begin() disables only preemption. If the reader is in preemptible context and the writer side (u64_stats_update_begin*()) runs in an interrupt context (IRQ or softirq) then the writer can update the stats during the read operation. This update remains undetected. Use u64_stats_fetch_begin_irq() to ensure the stats fetch on 32bit-UP are not interrupted by a writer. 32bit-SMP remains unaffected by this change. Cc: "David S.

[PATCH openEuler-1.0-LTS 1/3] mm: hwpoison: refactor refcount check handling
by Yongqiang Liu 04 Feb '23

04 Feb '23

From: Yang Shi <shy828301(a)gmail.com> stable inclusion from stable-v5.15.86 commit a62b1bc603a1ded739e7cf543da29a3eb93cc534 category: bugfix bugzilla: https://gitee.com/openeuler/kernel/issues/I6AR36 CVE: NA Reference: https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git/commit/?id… -------------------------------- commit dd0f230a0a80ff396c7ce587f16429f2a8131344 upstream. Memory failure will report failure if the page still has extra pinned refcount other than from hwpoison after the handler is done. Actually the check is not necessary for all handlers, so move the check into specific handlers. This would make the following keeping shmem page in page cache patch easier. There may be expected extra pin for some cases, for example, when the page is dirty and in swapcache.

[PATCH openEuler-1.0-LTS 1/6] dhugetlb: backport dynamic hugetlb feature
by Yongqiang Liu 04 Feb '23

04 Feb '23

From: Liu Shixin <liushixin2(a)hauwei.com> hulk inclusion category: feature bugzilla: 46904, https://gitee.com/openeuler/kernel/issues/I6BDME CVE: NA -------------------------------- This feature has already beed supported on x86_64 and this is the origin description: Dynamic hugetlb which is based on Hugetlb, supports to be splited dynamically in a specified cgroup. We add a hugetlb_pool in a mem_cgroup to manage dynamic hugetlb for corresponding cgroup. After dynamic hugepages are allocated for a cgroup, these hugepages can be used as 1G/2M/4K pages by split/merge opreation. It is now supported on arm64. This feature will be limited to depends on ARM64_4K_PAGES and not support cont-bits hugepage. We merge the previous patches into one patch which is patch[1]. While merge the code ,we found some code can be isolated by config DYNAMIC_HUGETLB, so we add patch[2] to re-isolated them. In patch[3], we restrict the feature on mentioned limit. The patch[4] add skip of dissolve hugepage which may conflict with memory hotplug and memory failure. The patch[5] set DYNAMIC_HUGETLB to y in hulk_defconfig to enable by default. This patch includes all previous patches and the patches list is recorded in bugzilla.

[OLK-5.10 1/3] net: Use u64_stats_fetch_begin_irq() for stats fetch.
by Wang Yufen 03 Feb '23

03 Feb '23

From: Sebastian Andrzej Siewior <bigeasy(a)linutronix.de> stable inclusion from stable-v5.10.142 commit d71a1c9fce184718d1b3a51a9e8a6e31cbbb45ce category: bugfix bugzilla: 188217 Reference: https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git/commit/?id… ------------------------------------------------- commit 278d3ba61563ceed3cb248383ced19e14ec7bc1f upstream. On 32bit-UP u64_stats_fetch_begin() disables only preemption. If the reader is in preemptible context and the writer side (u64_stats_update_begin*()) runs in an interrupt context (IRQ or softirq) then the writer can update the stats during the read operation. This update remains undetected. Use u64_stats_fetch_begin_irq() to ensure the stats fetch on 32bit-UP are not interrupted by a writer. 32bit-SMP remains unaffected by this change. Cc: "David S.

[OLK-5.10 1/7] geneve: do not use RT_TOS for IPv6 flowlabel
by Wang Yufen 03 Feb '23

03 Feb '23

From: Matthias May <matthias.may(a)westermo.com> stable inclusion from stable-v5.10.138 commit 38b83883ce4e4efe8ff0a727192219cac2668d42 category: bugfix bugzilla: 188217 Reference: https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git/commit/?id… ------------------------------------------------- commit ca2bb69514a8bc7f83914122f0d596371352416c upstream. According to Guillaume Nault RT_TOS should never be used for IPv6. Quote: RT_TOS() is an old macro used to interprete IPv4 TOS as described in the obsolete RFC 1349. It's conceptually wrong to use it even in IPv4 code, although, given the current state of the code, most of the existing calls have no consequence. But using RT_TOS() in IPv6 code is always a bug: IPv6 never had a "TOS" field to be interpreted the RFC 1349 way. There's no historical compatibility to worry about.

From: Szymon Heidrich <szymon.heidrich(a)gmail.com> maillist inclusion category: bugfix bugzilla: https://gitee.com/src-openeuler/kernel/issues/I6AQJP CVE: CVE-2023-23559 Reference: https://patchwork.kernel.org/project/linux-wireless/patch/20230111175031.70… ------------------------------- Since resplen and respoffs are signed integers sufficiently large values of unsigned int len and offset members of RNDIS response will result in negative values of prior variables. This may be utilized to bypass implemented security checks to either extract memory contents by manipulating offset or overflow the data buffer via memcpy by manipulating both offset and len.

Prior to this commit the following command would trigger an unhandled page fault in the kernel: root@(none):/linus/fs/fat# insmod ./fat.ko "foo=bar \"" [ 33.870507] BUG: unable to handle page fault for address: ffff888204252608 [ 33.872180] #PF: supervisor read access in kernel mode [ 33.873414] #PF: error_code(0x0000) - not-present page [ 33.874650] PGD 4401067 P4D 4401067 PUD 0 [ 33.875321] Oops: 0000 [#1] SMP DEBUG_PAGEALLOC PTI [ 33.876113] CPU: 16 PID: 399 Comm: insmod Not tainted 5.19.0-dbg-DEV #4 [ 33.877193] Hardware name: QEMU Standard PC (i440FX + PIIX, 1996), BIOS 1.16.0-debian-1.16.0-4 04/01/2014 [ 33.878739] RIP: 0010:next_arg+0xd1/0x110 [ 33.879399] Code: 22 75 1d 41 c6 04 01 00 41 80 f8 22 74 18 eb 35 4c 89 0e 45 31 d2 4c 89 cf 48 c7 02 00 00 00 00 41 80 f8 22 75 1f 41 8d 42 ff <41> 80 3c 01 22 75 14 41 c6 04 01 00 eb 0d 48 c7 02 00 00 00 00 41 [ 33.882338] RSP: 0018:ffffc90001253d08 EFLAGS: 00010246 [ 33.883174] RAX: 00000000ffffffff RBX: ffff888104252608 RCX: 0fc317bba1c1dd00 [ 33.884311] RDX: ffffc90001253d40 RSI: ffffc90001253d48 RDI: ffff888104252609 [ 33.885450] RBP: ffffc90001253d10 R08: 0000000000000022 R09: ffff888104252609 [ 33.886595] R10: 0000000000000000 R11: ffffffff82c7ff20 R12: 0000000000000282 [ 33.887748] R13: 00000000ffff8000 R14: 0000000000000000 R15: 0000000000007fff [ 33.888887] FS: 00007f04ec7432c0(0000) GS:ffff88813d300000(0000) knlGS:0000000000000000 [ 33.890183] CS: 0010 DS: 0000 ES: 0000 CR0: 0000000080050033 [ 33.891111] CR2: ffff888204252608 CR3: 0000000100f36005 CR4: 0000000000170ee0 [ 33.892241] Call Trace: [ 33.892641] <TASK> [ 33.892989] parse_args+0x8f/0x220 [ 33.893538] load_module+0x138b/0x15a0 [ 33.894149] ? prepare_coming_module+0x50/0x50 [ 33.894879] ? kernel_read_file_from_fd+0x5f/0x90 [ 33.895639] __se_sys_finit_module+0xce/0x130 [ 33.896342] __x64_sys_finit_module+0x1d/0x20 [ 33.897042] do_syscall_64+0x44/0xa0 [ 33.897622] entry_SYSCALL_64_after_hwframe+0x63/0xcd [ 33.898434] RIP: 0033:0x7f04ec85ef79 [ 33.899009] Code: 48 8d 3d da db 0d 00 0f 05 eb a5 66 0f 1f 44 00 00 48 89 f8 48 89 f7 48 89 d6 48 89 ca 4d 89 c2 4d 89 c8 4c 8b 4c 24 08 0f 05 <48> 3d 01 f0 ff ff 73 01 c3 48 8b 0d c7 9e 0d 00 f7 d8 64 89 01 48 [ 33.901912] RSP: 002b:00007fffae81bfe8 EFLAGS: 00000246 ORIG_RAX: 0000000000000139 [ 33.903081] RAX: ffffffffffffffda RBX: 0000559c5f1d2640 RCX: 00007f04ec85ef79 [ 33.904191] RDX: 0000000000000000 RSI: 0000559c5f1d12a0 RDI: 0000000000000003 [ 33.905304] RBP: 0000000000000000 R08: 0000000000000000 R09: 0000000000000000 [ 33.906421] R10: 0000000000000003 R11: 0000000000000246 R12: 0000559c5f1d12a0 [ 33.907526] R13: 0000000000000000 R14: 0000559c5f1d25f0 R15: 0000559c5f1d12a0 [ 33.908631] </TASK> [ 33.908986] Modules linked in: fat(+) [last unloaded: fat] [ 33.909843] CR2: ffff888204252608 [ 33.910375] ---[ end trace 0000000000000000 ]--- [ 33.911172] RIP: 0010:next_arg+0xd1/0x110 [ 33.911796] Code: 22 75 1d 41 c6 04 01 00 41 80 f8 22 74 18 eb 35 4c 89 0e 45 31 d2 4c 89 cf 48 c7 02 00 00 00 00 41 80 f8 22 75 1f 41 8d 42 ff <41> 80 3c 01 22 75 14 41 c6 04 01 00 eb 0d 48 c7 02 00 00 00 00 41 [ 33.914643] RSP: 0018:ffffc90001253d08 EFLAGS: 00010246 [ 33.915446] RAX: 00000000ffffffff RBX: ffff888104252608 RCX: 0fc317bba1c1dd00 [ 33.916544] RDX: ffffc90001253d40 RSI: ffffc90001253d48 RDI: ffff888104252609 [ 33.917636] RBP: ffffc90001253d10 R08: 0000000000000022 R09: ffff888104252609 [ 33.918727] R10: 0000000000000000 R11: ffffffff82c7ff20 R12: 0000000000000282 [ 33.919821] R13: 00000000ffff8000 R14: 0000000000000000 R15: 0000000000007fff [ 33.920908] FS: 00007f04ec7432c0(0000) GS:ffff88813d300000(0000) knlGS:0000000000000000 [ 33.922125] CS: 0010 DS: 0000 ES: 0000 CR0: 0000000080050033 [ 33.923017] CR2: ffff888204252608 CR3: 0000000100f36005 CR4: 0000000000170ee0 [ 33.924098] Kernel panic - not syncing: Fatal exception [ 33.925776] Kernel Offset: disabled [ 33.926347] Rebooting in 10 seconds..

From: Huajingjing <huajingjing1(a)huawei.com> driver inclusion category: bugfix bugzilla: https://gitee.com/openeuler/kernel/issues/I67J42 CVE: NA ------------------------------------------------- The BMA software is a system management software offered by Huawei. It supports the status monitoring, performance monitoring and event monitoring of various components, including server CPUs, memory hard disks, NICs, IB cards, PCIe cards, RAID controller cards and optical modules. In this version, the system resets due to the BMA spin lock when the memory usage is too high, the vulnerability has been rectified.

When checking for libc rseq support in the library constructor, don't only depend on the symbols presence, check that the registration was completed. This targets a scenario where the libc has rseq support but it is not wired for the current architecture in 'bits/rseq.h', we want to fallback to our internal registration mechanism.

[PATCH openEuler-5.10-LTS-SP1 01/14] tracing/osnoise: Properly unhook events if start_per_cpu_kthreads() fails

On the next tracer enable, hooks get not installed due to trace_osnoise_callback_enabled flag. And on the further tracer disable an attempt to remove non-installed hooks happened, hitting a WARN_ON_ONCE() in tracepoint_remove_func(). Fix the error path by adding the missing part of cleanup. While at this, introduce osnoise_unhook_events() to avoid code duplication between this error path and normal tracer disable.

[PATCH openEuler-5.10-LTS 01/21] tmpfs: do not allocate pages on read
by Jialin Zhang 18 Jan '23

18 Jan '23

From: Hugh Dickins <hughd(a)google.com> mainline inclusion from mainline-v5.18-rc1 commit 56a8c8eb1eaf21261be8cdc4e3715239ac087342 category: bugfix bugzilla: https://gitee.com/openeuler/kernel/issues/I6113U CVE: NA Reference: https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git/commit/?id… -------------------------------- Mikulas asked in "Do we still need commit a0ee5ec520ed ('tmpfs: allocate on read when stacked')?" in [1] Lukas noticed this unusual behavior of loop device backed by tmpfs in [2]. Normally, shmem_file_read_iter() copies the ZERO_PAGE when reading holes; but if it looks like it might be a read for "a stacking filesystem", it allocates actual pages to the page cache, and even marks them as dirty. And reads from the loop device do satisfy the test that is used. This oddity was added for an old version of unionfs, to help to limit its usage to the limited size of the tmpfs mount involved; but about the same time as the tmpfs mod went in (2.6.25), unionfs was reworked to proceed differently; and the mod kept just in case others needed it. Do we still need it? I cannot answer with more certainty than "Probably not". It's nasty enough that we really should try to delete it; but if a regression is reported somewhere, then we might have to revert later. It's not quite as simple as just removing the test (as Mikulas did): xfstests generic/013 hung because splice from tmpfs failed on page not up-to-date and page mapping unset. That can be fixed just by marking the ZERO_PAGE as Uptodate, which of course it is: do so in pagecache_init() - it might be useful to others than tmpfs. My intention, though, was to stop using the ZERO_PAGE here altogether: surely iov_iter_zero() is better for this case? Sadly not: it relies on clear_user(), and the x86 clear_user() is slower than its copy_user() [3]. But while we are still using the ZERO_PAGE, let's stop dirtying its struct page cacheline with unnecessary get_page() and put_page().

When checking for libc rseq support in the library constructor, don't only depend on the symbols presence, check that the registration was completed. This targets a scenario where the libc has rseq support but it is not wired for the current architecture in 'bits/rseq.h', we want to fallback to our internal registration mechanism.

[PATCH openEuler-1.0-LTS 1/6] crypto: ecdh - avoid unaligned accesses in ecdh_set_secret()
by Yongqiang Liu 11 Jan '23

11 Jan '23

From: Ard Biesheuvel <ardb(a)kernel.org> stable inclusion from stable-v4.19.164 commit 85637bc064f4fd5539d4173798d8cb55dde7fc0a category: bugfix bugzilla: https://gitee.com/openeuler/kernel/issues/I65ZD2 CVE: NA -------------------------------- commit 17858b140bf49961b71d4e73f1c3ea9bc8e7dda0 upstream. ecdh_set_secret() casts a void* pointer to a const u64* in order to feed it into ecc_is_key_valid(). This is not generally permitted by the C standard, and leads to actual misalignment faults on ARMv6 cores. In some cases, these are fixed up in software, but this still leads to performance hits that are entirely avoidable. So let's copy the key into the ctx buffer first, which we will do anyway in the common case, and which guarantees correct alignment.

[PATCH openEuler-1.0-LTS 1/8] mm/hwpoison: do not lock page again when me_huge_page() successfully recovers
by Yongqiang Liu 11 Jan '23

11 Jan '23

From: Naoya Horiguchi <naoya.horiguchi(a)nec.com> mainline inclusion from mainline-v5.13 commit ea6d0630100b285f059d0a8d8e86f38a46407536 category: bugfix bugzilla: 188222, https://gitee.com/openeuler/kernel/issues/I69SHF CVE: NA -------------------------------- Currently me_huge_page() temporary unlocks page to perform some actions then locks it again later. My testcase (which calls hard-offline on some tail page in a hugetlb, then accesses the address of the hugetlb range) showed that page allocation code detects this page lock on buddy page and printed out "BUG: Bad page state" message. check_new_page_bad() does not consider a page with __PG_HWPOISON as bad page, so this flag works as kind of filter, but this filtering doesn't work in this case because the "bad page" is not the actual hwpoisoned page. So stop locking page again. Actions to be taken depend on the page type of the error, so page unlocking should be done in ->action() callbacks. So let's make it assumed and change all existing callbacks that way.

From: Tony Lu <tonylu(a)linux.alibaba.com> anolis inclusion from devel-5.10-v5.10.134-12 commit b90e28f7170e1ae40c572f9f80a50bbdc8f8b99f category: feature bugzilla: https://gitee.com/openeuler/kernel/issues/I697AN CVE: NA Reference: https://gitee.com/anolis/cloud-kernel/commit/b90e28f7170e1ae40c572f9f80a50b… --------------------------- OpenAnolis Bug Tracker:0000282 This is achieved by broadcasting ARP or ND packets to all of its slave devices on transmit side. The switch will take further actions based on proper configuration. A new sysctl knob "net.bonding.broadcast_arp_or_nd" is introduced which controls the behaviour of broadcasting.

[PATCH openEuler-5.10-LTS 1/9] xfs: get rid of assert from xfs_btree_islastblock
by Zheng Zengkai 06 Jan '23

06 Jan '23

From: Guo Xuenan <guoxuenan(a)huawei.com> mainline inclusion from mainline-v6.1-rc4 commit 8c25febf23963431686f04874b96321288504127 category: bugfix bugzilla: https://gitee.com/openeuler/kernel/issues/I4KIAO CVE: NA Reference: https://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git/commit/?… -------------------------------- xfs_btree_check_block contains debugging knobs. With XFS_DEBUG setting up, turn on the debugging knob can trigger the assert of xfs_btree_islastblock, test script as follows: while true do mount $disk $mountpoint fsstress -d $testdir -l 0 -n 10000 -p 4 >/dev/null echo 1 > /sys/fs/xfs/sda/errortag/btree_chk_sblk sleep 10 umount $mountpoint done Kick off fsstress and only *then* turn on the debugging knob. If it happens that the knob gets turned on after the cntbt lookup succeeds but before the call to xfs_btree_islastblock, then we *can* end up in the situation where a previously checked btree block suddenly starts returning EFSCORRUPTED from xfs_btree_check_block. Kaboom. Darrick give a very detailed explanation as follows: Looking back at commit 27d9ee577dcce, I think the point of all this was to make sure that the cursor has actually performed a lookup, and that the btree block at whatever level we're asking about is ok. If the caller hasn't ever done a lookup, the bc_levels array will be empty, so cur->bc_levels[level].bp pointer will be NULL. The call to xfs_btree_get_block will crash anyway, so the "ASSERT(block);" part is pointless. If the caller did a lookup but the lookup failed due to block corruption, the corresponding cur->bc_levels[level].bp pointer will also be NULL, and we'll still crash. The "ASSERT(xfs_btree_check_block);" logic is also unnecessary. If the cursor level points to an inode root, the block buffer will be incore, so it had better always be consistent. If the caller ignores a failed lookup after a successful one and calls this function, the cursor state is garbage and the assert wouldn't have tripped anyway. So get rid of the assert.

[PATCH openEuler-1.0-LTS 1/2] misc: sgi-gru: fix use-after-free error in gru_set_context_option, gru_fault and gru_handle_user_call_os
by Yongqiang Liu 05 Jan '23

From: Zheng Wang <zyytlz.wz(a)163.com> mainline inclusion from mainline-v6.2-rc1 commit 643a16a0eb1d6ac23744bb6e90a00fc21148a9dc category: bugfix bugzilla: https://gitee.com/src-openeuler/kernel/issues/I5UBUF CVE: CVE-2022-3424 Reference: https://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git/commit?i… -------------------------------- In some bad situation, the gts may be freed gru_check_chiplet_assignment. The call chain can be gru_unload_context->gru_free_gru_context->gts_drop and kfree finally. However, the caller didn't know if the gts is freed or not and use it afterwards. This will trigger a Use after Free bug. Fix it by introducing a return value to see if it's in error path or not. Free the gts in caller if gru_check_chiplet_assignment check failed.
