[PATCH] drm/atomic-helper: Bump vblank timeout to 100 ms
by jiazhenyuan＠uniontech.com 21 Jun '22

21 Jun '22

Presumably this is because the DSI display is command-mode only and the state machine will take some time setting up its state for the first display update, and we hit a timeout. 100 ms makes it pass without problems.

[PATCH openEuler-1.0-LTS] RDMA/cma: Do not change route.addr.src_addr.ss_family
by tangbin 21 Jun '22

21 Jun '22

From: Jason Gunthorpe <jgg(a)nvidia.com> mainline inclusion from mainline-v5.15-rc4 commit bc0bdc5afaa740d782fbf936aaeebd65e5c2921d category: bugfix bugzilla: https://gitee.com/openeuler/kernel/issues/I59840 CVE: CVE-2021-4028 -------------------------------- Conflicts: The conditional statement to verify RDMA_CM_IDLE state is a little bit different from the upstream to 4.19. The commit 732d41c545bb (RDMA/cma: Make the locking for automatic state transition more clear) is missing from 4.19. So, the context has been modified. If the state is not idle then rdma_bind_addr() will immediately fail and no change to global state should happen. For instance if the state is already RDMA_CM_LISTEN then this will corrupt the src_addr and would cause the test in cma_cancel_operation(): if (cma_any_addr(cma_src_addr(id_priv)) && !id_priv->cma_dev) To view a mangled src_addr, eg with a IPv6 loopback address but an IPv4 family, failing the test. This would manifest as this trace from syzkaller: BUG: KASAN: use-after-free in __list_add_valid+0x93/0xa0 lib/list_debug.c:26 Read of size 8 at addr ffff8881546491e0 by task syz-executor.1/32204 CPU: 1 PID: 32204 Comm: syz-executor.1 Not tainted 5.12.0-rc8-syzkaller #0 Hardware name: Google Google Compute Engine/Google Compute Engine, BIOS Google 01/01/2011 Call Trace: __dump_stack lib/dump_stack.c:79 [inline] dump_stack+0x141/0x1d7 lib/dump_stack.c:120 print_address_description.constprop.0.cold+0x5b/0x2f8 mm/kasan/report.c:232 __kasan_report mm/kasan/report.c:399 [inline] kasan_report.cold+0x7c/0xd8 mm/kasan/report.c:416 __list_add_valid+0x93/0xa0 lib/list_debug.c:26 __list_add include/linux/list.h:67 [inline] list_add_tail include/linux/list.h:100 [inline] cma_listen_on_all drivers/infiniband/core/cma.c:2557 [inline] rdma_listen+0x787/0xe00 drivers/infiniband/core/cma.c:3751 ucma_listen+0x16a/0x210 drivers/infiniband/core/ucma.c:1102 ucma_write+0x259/0x350 drivers/infiniband/core/ucma.c:1732 vfs_write+0x28e/0xa30 fs/read_write.c:603 ksys_write+0x1ee/0x250 fs/read_write.c:658 do_syscall_64+0x2d/0x70 arch/x86/entry/common.c:46 entry_SYSCALL_64_after_hwframe+0x44/0xae Which is indicating that an rdma_id_private was destroyed without doing cma_cancel_listens().

[PATCH openEuler-1.0-LTS 1/2] tcp: change source port randomizarion at connect() time
by Yongqiang Liu 17 Jun '22

17 Jun '22

From: Eric Dumazet <edumazet(a)google.com> stable inclusion from stable-v4.19.246 commit ddec440133913a6b8880e53b896d521a4b7ff24f category: bugfix bugzilla: https://gitee.com/src-openeuler/kernel/issues/I5C3A9 CVE: CVE-2022-32296 -------------------------------- commit 190cc82489f46f9d88e73c81a47e14f80a791e1a upstream. RFC 6056 (Recommendations for Transport-Protocol Port Randomization) provides good summary of why source selection needs extra care. David Dworken reminded us that linux implements Algorithm 3 as described in RFC 6056 3.3.3 Quoting David : In the context of the web, this creates an interesting info leak where websites can count how many TCP connections a user's computer is establishing over time. For example, this allows a website to count exactly how many subresources a third party website loaded. This also allows: - Distinguishing between different users behind a VPN based on distinct source port ranges. - Tracking users over time across multiple networks. - Covert communication channels between different browsers/browser profiles running on the same computer - Tracking what applications are running on a computer based on the pattern of how fast source ports are getting incremented. Section 3.3.4 describes an enhancement, that reduces attackers ability to use the basic information currently stored into the shared 'u32 hint'.

[PATCH openEuler-1.0-LTS 1/3] powerpc/32: Fix overread/overwrite of thread_struct via ptrace
by Yongqiang Liu 15 Jun '22

15 Jun '22

From: Michael Ellerman <mpe(a)ellerman.id.au> mainline inclusion from mainline-v5.19-rc2 commit 8e1278444446fc97778a5e5c99bca1ce0bbc5ec9 category: bugfix bugzilla: https://gitee.com/src-openeuler/kernel/issues/I5C43D CVE: CVE-2022-32981 -------------------------------- The ptrace PEEKUSR/POKEUSR (aka PEEKUSER/POKEUSER) API allows a process to read/write registers of another process. To get/set a register, the API takes an index into an imaginary address space called the "USER area", where the registers of the process are laid out in some fashion. The kernel then maps that index to a particular register in its own data structures and gets/sets the value. The API only allows a single machine-word to be read/written at a time. So 4 bytes on 32-bit kernels and 8 bytes on 64-bit kernels. The way floating point registers (FPRs) are addressed is somewhat complicated, because double precision float values are 64-bit even on 32-bit CPUs. That means on 32-bit kernels each FPR occupies two word-sized locations in the USER area. On 64-bit kernels each FPR occupies one word-sized location in the USER area. Internally the kernel stores the FPRs in an array of u64s, or if VSX is enabled, an array of pairs of u64s where one half of each pair stores the FPR. Which half of the pair stores the FPR depends on the kernel's endianness. To handle the different layouts of the FPRs depending on VSX/no-VSX and big/little endian, the TS_FPR() macro was introduced. Unfortunately the TS_FPR() macro does not take into account the fact that the addressing of each FPR differs between 32-bit and 64-bit kernels. It just takes the index into the "USER area" passed from userspace and indexes into the fp_state.fpr array. On 32-bit there are 64 indexes that address FPRs, but only 32 entries in the fp_state.fpr array, meaning the user can read/write 256 bytes past the end of the array. Because the fp_state sits in the middle of the thread_struct there are various fields than can be overwritten, including some pointers. As such it may be exploitable. It has also been observed to cause systems to hang or otherwise misbehave when using gdbserver, and is probably the root cause of this report which could not be easily reproduced: https://lore.kernel.org/linuxppc-dev/dc38afe9-6b78-f3f5-666b-986939e40fc6@k… Rather than trying to make the TS_FPR() macro even more complicated to fix the bug, or add more macros, instead add a special-case for 32-bit kernels. This is more obvious and hopefully avoids a similar bug happening again in future. Note that because 32-bit kernels never have VSX enabled the code doesn't need to consider TS_FPRWIDTH/OFFSET at all. Add a BUILD_BUG_ON() to ensure that 32-bit && VSX is never enabled.

[PATCH openEuler-1.0-LTS] sctp: use call_rcu to free endpoint

To prevent the sk free, as a holder of the sk, ep should be alive when calling lock_sock(). This patch uses call_rcu() and moves sock_put and ep free into sctp_endpoint_destroy_rcu(), so that it's safe to try to hold the ep under rcu_read_lock in sctp_transport_traverse_process(). If sctp_endpoint_hold() returns true, it means this ep is still alive and we have held it and can continue to dump it; If it returns false, it means this ep is dead and can be freed after rcu_read_unlock, and we should skip it. In sctp_sock_dump(), after locking the sk, if this ep is different from tsp->asoc->ep, it means during this dumping, this asoc was peeled off before calling lock_sock(), and the sk should be skipped; If this ep is the same with tsp->asoc->ep, it means no peeloff happens on this asoc, and due to lock_sock, no peeloff will happen either until release_sock. Note that delaying endpoint free won't delay the port release, as the port release happens in sctp_endpoint_destroy() before calling call_rcu(). Also, freeing endpoint by call_rcu() makes it safe to access the sk by asoc->base.sk in sctp_assocs_seq_show() and sctp_rcv(). Thanks Jones to bring this issue up. v1->v2: - improve the changelog. - add kfree(ep) into sctp_endpoint_destroy_rcu(), as Jakub noticed.

A number of HID drivers already call hid_is_using_ll_driver() but only for the detection of if this is a USB device or not. Make this more obvious by creating hid_is_usb() and calling the function that way. Also converts the existing hid_is_using_ll_driver() functions to use the new call.

[PATCH openEuler-1.0-LTS] netfilter: nf_tables: disallow non-stateful expression in sets earlier
by Yongqiang Liu 14 Jun '22

14 Jun '22

From: Pablo Neira Ayuso <pablo(a)netfilter.org> mainline inclusion from mainline-v5.19-rc1 commit 520778042ccca019f3ffa136dd0ca565c486cedd category: bugfix bugzilla: 186905, https://gitee.com/src-openeuler/kernel/issues/I5B3QZ CVE: CVE-2022-1966 -------------------------------- Since 3e135cd499bf ("netfilter: nft_dynset: dynamic stateful expression instantiation"), it is possible to attach stateful expressions to set elements. cd5125d8f518 ("netfilter: nf_tables: split set destruction in deactivate and destroy phase") introduces conditional destruction on the object to accomodate transaction semantics. nft_expr_init() calls expr->ops->init() first, then check for NFT_STATEFUL_EXPR, this stills allows to initialize a non-stateful lookup expressions which points to a set, which might lead to UAF since the set is not properly detached from the set->binding for this case. Anyway, this combination is non-sense from nf_tables perspective. This patch fixes this problem by checking for NFT_STATEFUL_EXPR before expr->ops->init() is called. The reporter provides a KASAN splat and a poc reproducer (similar to those autogenerated by syzbot to report use-after-free errors). It is unknown to me if they are using syzbot or if they use similar automated tool to locate the bug that they are reporting. For the record, this is the KASAN splat.

[PATCH openEuler-1.0-LTS] nvme: Assign subsys instance from first ctrl
by Chen Taotao 09 Jun '22

09 Jun '22

mainline inclusion from mainline-5.3.0-rc3 commit 733e4b69d508d03c20adfdcf4bd27abc60fae9cc category: bugfix bugzilla: https://gitee.com/openeuler/kernel/issues/I5986O CVE: NA -------------------------------- The namespace disk names must be unique for the lifetime of the subsystem. This was accomplished by using their parent subsystems' instances which were allocated independently from the controllers connected to that subsystem. This allowed name prefixes assigned to namespaces to match a controller from an unrelated subsystem, and has created confusion among users examining device nodes. Ensure a namespace's subsystem instance never clashes with a controller instance of another subsystem by transferring the instance ownership to the parent subsystem from the first controller discovered in that subsystem.

[PATCH] nvme: Assign subsys instance from first ctrl upstream 733e4b69
by Chen Taotao 06 Jun '22

06 Jun '22

The namespace disk names must be unique for the lifetime of the subsystem. This was accomplished by using their parent subsystems' instances which were allocated independently from the controllers connected to that subsystem. This allowed name prefixes assigned to namespaces to match a controller from an unrelated subsystem, and has created confusion among users examining device nodes. Ensure a namespace's subsystem instance never clashes with a controller instance of another subsystem by transferring the instance ownership to the parent subsystem from the first controller discovered in that subsystem.

[PATCH OLK-5.10 0/4] eulerfs: improve the creation of persister
by Gou Hao 02 Jun '22

02 Jun '22

Patch series "improve the creation of persister". The main modification is to create a persistent thread only when a NUMA node has an online CPU at least, instead of on all NUMA nodes. In the current code, the number of NUMA nodes is obtained when the module is loaded, and the same number of persistent threads are created when the file system is mounted. However, we should ignore NUMA nodes that do not have an online CPU. So we should decide how many threads to create according to the online CPU condition when initializing persist. Patch4 is a bugfix about dep_init(). Gou Hao (4): eulerfs: add socket_num to eufs_sb_info eulerfs: create persister on node when it has online cpu eulerfs: record persister num eulerfs: fix potential sbi->persisters free error fs/eulerfs/dep.c | 48 +++++++++++++++++++++++++++--------------- fs/eulerfs/euler.h | 2 -- fs/eulerfs/euler_def.h | 1 + fs/eulerfs/super.c | 21 ++++-------------- 4 files changed, 36 insertions(+), 36 deletions(-) -- 2.20.1

[PATCH openEuler-5.10-LTS 01/31] 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 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

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

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.

[PATCH openEuler-5.10 01/26] readahead: introduce FMODE_CTL_WILLNEED to read first 2MB of file
by Zheng Zengkai 23 May '22

23 May '22

From: Yufen Yu <yuyufen(a)huawei.com> hulk inclusion category: feature bugzilla: https://gitee.com/openeuler/kernel/issues/I53R0H CVE: NA backport: openEuler-22.03-LTS ------------------------------------------------- In some scenario, likely spark-sql, almost all meta file's size is less then 2MB and applications read these smaller files in random mode. That means, it may issue multiple times random io to rotate disk, which can cause performance degradation. To improve the small files random read, we try to read the first 2MB into pagecache on the first time of read. Then it can avoid multiple random io. In fact, applications can call fadvise system with POSIX_FADV_WILLNEED to achieve this goal. But, some apps may cannot easily do that. So, we provide a new file flag FMODE_CTL_WILLNEED.

[PATCH openEuler-5.10 01/39] skmsg: Lock ingress_skb when purging
by Zheng Zengkai 21 May '22

21 May '22

From: Wang Yufen <wangyufen(a)huawei.com> mainline inclusion from mainline-v5.13-rc1 commit 37f0e514db660f03f8982b8f4fbbd4b2740abe7d category: feature bugzilla: https://gitee.com/openeuler/kernel/issues/I545NW Reference: https://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git/commit/?… -------------------------------- Currently we purge the ingress_skb queue only when psock refcnt goes down to 0, so locking the queue is not necessary, but in order to be called during ->close, we have to lock it here.

[PATCH openEuler-5.10 1/2] net/x25: Fix null-ptr-deref caused by x25_disconnect

From: Duoming Zhou <duoming(a)zju.edu.cn> stable inclusion from stable-v5.10.110 commit 5c94b6205e87411dbe9dc1ca088eb36b8837fb47 category: bugfix bugzilla: https://gitee.com/src-openeuler/kernel/issues/I5661B CVE: CVE-2022-1516 Reference: https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git/commit/?id… -------------------------------- [ Upstream commit 7781607938c8371d4c2b243527430241c62e39c2 ] When the link layer is terminating, x25->neighbour will be set to NULL in x25_disconnect(). As a result, it could cause null-ptr-deref bugs in x25_sendmsg(),x25_recvmsg() and x25_connect(). One of the bugs is shown below. (Thread 1) | (Thread 2) x25_link_terminated() | x25_recvmsg() x25_kill_by_neigh() | ... x25_disconnect() | lock_sock(sk) ... | ... x25->neighbour = NULL //(1) | ... | x25->neighbour->extended //(2) The code sets NULL to x25->neighbour in position (1) and dereferences x25->neighbour in position (2), which could cause null-ptr-deref bug. This patch adds lock_sock() in x25_kill_by_neigh() in order to synchronize with x25_sendmsg(), x25_recvmsg() and x25_connect(). What`s more, the sock held by lock_sock() is not NULL, because it is extracted from x25_list and uses x25_list_lock to synchronize.

[PATCH openEuler-5.10 01/43] rcu: Prevent expedited GP from enabling tick on offline CPU
by Zheng Zengkai 10 May '22

10 May '22

From: "Paul E. McKenney" <paulmck(a)kernel.org> mainline inclusion from mainline-v5.17-rc1 commit 147f04b14adde831eb4a0a1e378667429732f9e8 category: bugfix bugzilla: https://gitee.com/openeuler/kernel/issues/I53ILL CVE: NA ------------------------------------------------------------------------- If an RCU expedited grace period starts just when a CPU is in the process of going offline, so that the outgoing CPU has completed its pass through stop-machine but has not yet completed its final dive into the idle loop, RCU will attempt to enable that CPU's scheduling-clock tick via a call to tick_dep_set_cpu(). For this to happen, that CPU has to have been online when the expedited grace period completed its CPU-selection phase. This is pointless: The outgoing CPU has interrupts disabled, so it cannot take a scheduling-clock tick anyway. In addition, the tick_dep_set_cpu() function's eventual call to irq_work_queue_on() will splat as follows: smpboot: CPU 1 is now offline WARNING: CPU: 6 PID: 124 at kernel/irq_work.c:95 +irq_work_queue_on+0x57/0x60 Modules linked in: CPU: 6 PID: 124 Comm: kworker/6:2 Not tainted 5.15.0-rc1+ #3 Hardware name: QEMU Standard PC (Q35 + ICH9, 2009), BIOS +rel-1.14.0-0-g155821a-rebuilt.opensuse.org 04/01/2014 Workqueue: rcu_gp wait_rcu_exp_gp RIP: 0010:irq_work_queue_on+0x57/0x60 Code: 8b 05 1d c7 ea 62 a9 00 00 f0 00 75 21 4c 89 ce 44 89 c7 e8 +9b 37 fa ff ba 01 00 00 00 89 d0 c3 4c 89 cf e8 3b ff ff ff eb ee <0f> 0b eb b7 +0f 0b eb db 90 48 c7 c0 98 2a 02 00 65 48 03 05 91 6f RSP: 0000:ffffb12cc038fe48 EFLAGS: 00010282 RAX: 0000000000000001 RBX: 0000000000005208 RCX: 0000000000000020 RDX: 0000000000000001 RSI: 0000000000000001 RDI: ffff9ad01f45a680 RBP: 000000000004c990 R08: 0000000000000001 R09: ffff9ad01f45a680 R10: ffffb12cc0317db0 R11: 0000000000000001 R12: 00000000fffecee8 R13: 0000000000000001 R14: 0000000000026980 R15: ffffffff9e53ae00 FS: 0000000000000000(0000) GS:ffff9ad01f580000(0000) +knlGS:0000000000000000 CS: 0010 DS: 0000 ES: 0000 CR0: 0000000080050033 CR2: 0000000000000000 CR3: 000000000de0c000 CR4: 00000000000006e0 DR0: 0000000000000000 DR1: 0000000000000000 DR2: 0000000000000000 DR3: 0000000000000000 DR6: 00000000fffe0ff0 DR7: 0000000000000400 Call Trace: tick_nohz_dep_set_cpu+0x59/0x70 rcu_exp_wait_wake+0x54e/0x870 ? sync_rcu_exp_select_cpus+0x1fc/0x390 process_one_work+0x1ef/0x3c0 ? process_one_work+0x3c0/0x3c0 worker_thread+0x28/0x3c0 ? process_one_work+0x3c0/0x3c0 kthread+0x115/0x140 ? set_kthread_struct+0x40/0x40 ret_from_fork+0x22/0x30 ---[ end trace c5bf75eb6aa80bc6 ]--- This commit therefore avoids invoking tick_dep_set_cpu() on offlined CPUs to limit both futility and false-positive splats.

[PATCH openEuler-5.10 01/13] ixgbe: add the ability for the PF to disable VF link state
by Zheng Zengkai 27 Apr '22

27 Apr '22

From: Slawomir Mrozowicz <slawomirx.mrozowicz(a)intel.com> mainline inclusion from mainline-v5.18-rc1 commit 366fd1000995d4cf64e1a61a0d78a051550b9841 category: bugfix bugzilla: 186597, https://gitee.com/src-openeuler/kernel/issues/I532H9 CVE: CVE-2021-33061 Reference: https://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git/commit/?… -------------------------------- Add support for ndo_set_vf_link_state the Network Device Option that allows the PF driver to control the virtual link state of the VF devices. Without this change a VF cannot be disabled/enabled by the administrator. In the implementation the auto state takes over PF link state to VF link setting, the enable state is not supported, the disable state shut off the VF link regardless of the PF setting.

From: Hangyu Hua <hbh25y(a)gmail.com> stable inclusion from stable-v5.10.110 commit 5318cdf4fd834856ce71238b064f35386f9ef528 category: bugfix bugzilla: 186592 https://gitee.com/src-openeuler/kernel/issues/I51YBQ?from=project-issue CVE: CVE-2022-28388 Reference: https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git/commit/?id… -------------------------------- commit 3d3925ff6433f98992685a9679613a2cc97f3ce2 upstream.

[PATCH openEuler-1.0-LTS] x86/tsc: Make cur->adjusted values in package#1 to be the same
by LeoLiuoc 26 Apr '22

26 Apr '22

zhaoxin inclusion category: bugfix bugzilla: https://gitee.com/openeuler/kernel/issues/I54V2W CVE: NA ---------------------------------------------------------------- When resume from S4 on Zhaoxin 2 packages platform that support X86_FEATURE_TSC_ADJUST, the following warning messages appear: [ 327.445302] [Firmware Bug]: TSC ADJUST differs: CPU15 45960750 --> 78394770. Restoring [ 329.209120] [Firmware Bug]: TSC ADJUST differs: CPU14 45960750 --> 78394770. Restoring [ 329.209128] [Firmware Bug]: TSC ADJUST differs: CPU13 45960750 --> 78394770. Restoring [ 329.209138] [Firmware Bug]: TSC ADJUST differs: CPU12 45960750 --> 78394770. Restoring [ 329.209151] [Firmware Bug]: TSC ADJUST differs: CPU11 45960750 --> 78394770. Restoring [ 329.209160] [Firmware Bug]: TSC ADJUST differs: CPU10 45960750 --> 78394770. Restoring [ 329.209169] [Firmware Bug]: TSC ADJUST differs: CPU9 45960750 --> 78394770. Restoring The reason is: Step 1: Bring up. TSC is sync after bring up with following settings: MSR 0x3b cur->adjusted Package#0 CPU 0-7 0 0 Package#1 first CPU value1 value1 Package#1 non-first CPU value1 value1 Step 2: Suspend to S4. Settings in Step 1 are not changed in this Step. Step 3: Bring up caused by S4 wake up event. TSC is sync when bring up with following settings: MSR 0x3b cur->adjusted Package#0 CPU 0-7 0 0 Package#1 first CPU value2 value2 Package#1 non-first CPU value2 value2 Step 4: Resume from S4. When resuming from S4, Current TSC synchronous mechanism cause following settings: MSR 0x3b cur->adjusted Package#0 CPU 0-7 0 0 Package#1 first CPU value2 value2 Package#1 non-first CPU value2 value1 In these Steps, value1 != 0 and value2 != value1. In Step4, as function tsc_store_and_check_tsc_adjust() do, when the value of MSR 0x3b on the non-first online CPU in package#1 is equal to the value of cur->adjusted on the first online CPU in the same package, the cur->adjusted value on this non-first online CPU will hold the old value1. This cause function tsc_verify_tsc_adjust() set the value of MSR 0x3b on the non-first online CPUs in the package#1 to the old value1 and print the beginning warning messages. Fix it by setting cur->adjusted value on the non-first online CPU in a package to the value of MSR 0x3b on the same CPU when they are not equal.

zhaoxin inclusion category: bugfix bugzilla: https://gitee.com/openeuler/kernel/issues/I54V27 CVE: NA ---------------------------------------------------------------- In AHCI spec, PhyRdy Change Interrupt cannot coexist with Link Power Management (LPM). While LPM driver would disable PhyRdy Change interrupt without checking whether HBA supports LPM or not before enabling it. Therefore, if enabling LPM from LPM driver by default, we can not disable it from BIOS without influence Hotplug out capability.
