[PATCH OLK-6.6 v2] btrfs: fix data races when accessing the reserved amount of block reserves
by Baokun Li 28 Apr '24

28 Apr '24

From: Filipe Manana <fdmanana(a)suse.com> stable inclusion from stable-v6.6.23 commit 82220b1835baaebf4ae2e490f56353a341a09bd2 category: bugfix bugzilla: https://gitee.com/src-openeuler/kernel/issues/I9HKBL CVE: CVE-2024-26905 Reference: https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git/commit/?id… -------------------------------- [ Upstream commit e06cc89475eddc1f3a7a4d471524256152c68166 ] At space_info.c we have several places where we access the ->reserved field of a block reserve without taking the block reserve's spinlock first, which makes KCSAN warn about a data race since that field is always updated while holding the spinlock. The reports from KCSAN are like the following: [117.193526] BUG: KCSAN: data-race in btrfs_block_rsv_release [btrfs] / need_preemptive_reclaim [btrfs] [117.195148] read to 0x000000017f587190 of 8 bytes by task 6303 on cpu 3: [117.195172] need_preemptive_reclaim+0x222/0x2f0 [btrfs] [117.195992] __reserve_bytes+0xbb0/0xdc8 [btrfs] [117.196807] btrfs_reserve_metadata_bytes+0x4c/0x120 [btrfs] [117.197620] btrfs_block_rsv_add+0x78/0xa8 [btrfs] [117.198434] btrfs_delayed_update_inode+0x154/0x368 [btrfs] [117.199300] btrfs_update_inode+0x108/0x1c8 [btrfs] [117.200122] btrfs_dirty_inode+0xb4/0x140 [btrfs] [117.200937] btrfs_update_time+0x8c/0xb0 [btrfs] [117.201754] touch_atime+0x16c/0x1e0 [117.201789] filemap_read+0x674/0x728 [117.201823] btrfs_file_read_iter+0xf8/0x410 [btrfs] [117.202653] vfs_read+0x2b6/0x498 [117.203454] ksys_read+0xa2/0x150 [117.203473] __s390x_sys_read+0x68/0x88 [117.203495] do_syscall+0x1c6/0x210 [117.203517] __do_syscall+0xc8/0xf0 [117.203539] system_call+0x70/0x98 [117.203579] write to 0x000000017f587190 of 8 bytes by task 11 on cpu 0: [117.203604] btrfs_block_rsv_release+0x2e8/0x578 [btrfs] [117.204432] btrfs_delayed_inode_release_metadata+0x7c/0x1d0 [btrfs] [117.205259] __btrfs_update_delayed_inode+0x37c/0x5e0 [btrfs] [117.206093] btrfs_async_run_delayed_root+0x356/0x498 [btrfs] [117.206917] btrfs_work_helper+0x160/0x7a0 [btrfs] [117.207738] process_one_work+0x3b6/0x838 [117.207768] worker_thread+0x75e/0xb10 [117.207797] kthread+0x21a/0x230 [117.207830] __ret_from_fork+0x6c/0xb8 [117.207861] ret_from_fork+0xa/0x30 So add a helper to get the reserved amount of a block reserve while holding the lock. The value may be not be up to date anymore when used by need_preemptive_reclaim() and btrfs_preempt_reclaim_metadata_space(), but that's ok since the worst it can do is cause more reclaim work do be done sooner rather than later. Reading the field while holding the lock instead of using the data_race() annotation is used in order to prevent load tearing.

From: Dan Carpenter <dan.carpenter(a)linaro.org> mainline inclusion from mainline-v6.8-rc4 commit cffe487026be13eaf37ea28b783d9638ab147204 category: bugfix bugzilla: https://gitee.com/src-openeuler/kernel/issues/I9HJRD CVE: CVE-2024-26828 Reference: https://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git/commit/?… -------------------------------- In this loop, we step through the buffer and after each item we check if the size_left is greater than the minimum size we need. However, the problem is that "bytes_left" is type ssize_t while sizeof() is type size_t. That means that because of type promotion, the comparison is done as an unsigned and if we have negative bytes left the loop continues instead of ending.

When size > 0, nfs4_listxattr() does not return an error because either generic_listxattr() or nfs4_listxattr_nfs4_label() consumes exactly all the bytes then size is 0 when calling nfs4_listxattr_nfs4_user() which then triggers the following kernel BUG: [ 99.403778] kernel BUG at mm/usercopy.c:102!

[PATCH openEuler-1.0-LTS V1] sched/rt: Disallow writing invalid values to sched_rt_period_us
by Cheng Yu 27 Apr '24

27 Apr '24

From: Cyril Hrubis <chrubis(a)suse.cz> stable inclusion from stable-v4.19.308 commit 2d931472d4740d3ada7011cc4c3499948d3a22fa category: bugfix bugzilla: https://gitee.com/openeuler/kernel/issues/I9K4JZ Reference: https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git/commit/?h=… -------------------------------- [ Upstream commit 079be8fc630943d9fc70a97807feb73d169ee3fc ] The validation of the value written to sched_rt_period_us was broken because: - the sysclt_sched_rt_period is declared as unsigned int - parsed by proc_do_intvec() - the range is asserted after the value parsed by proc_do_intvec() Because of this negative values written to the file were written into a unsigned integer that were later on interpreted as large positive integers which did passed the check: if (sysclt_sched_rt_period <= 0) return EINVAL; This commit fixes the parsing by setting explicit range for both perid_us and runtime_us into the sched_rt_sysctls table and processes the values with proc_dointvec_minmax() instead. Alternatively if we wanted to use full range of unsigned int for the period value we would have to split the proc_handler and use proc_douintvec() for it however even the Documentation/scheduller/sched-rt-group.rst describes the range as 1 to INT_MAX. As far as I can tell the only problem this causes is that the sysctl file allows writing negative values which when read back may confuse userspace.

[PATCH openEuler-1.0-LTS V1] sched/rt: Fix sysctl_sched_rr_timeslice intial value
by Cheng Yu 27 Apr '24

27 Apr '24

From: Cyril Hrubis <chrubis(a)suse.cz> stable inclusion from stable-v4.19.308 commit 41b7572dea9f7196d075b40d5ac8aafdb5f4b0d4 category: bugfix bugzilla: https://gitee.com/openeuler/kernel/issues/I9K34B Reference: https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git/commit/?h=… -------------------------------- [ Upstream commit c7fcb99877f9f542c918509b2801065adcaf46fa ] There is a 10% rounding error in the intial value of the sysctl_sched_rr_timeslice with CONFIG_HZ_300=y.

The problem it found is the intial sysctl file value which was computed as: static int sysctl_sched_rr_timeslice = (MSEC_PER_SEC / HZ) * RR_TIMESLICE; which works fine as long as MSEC_PER_SEC is multiple of HZ, however it introduces 10% rounding error for CONFIG_HZ_300: (MSEC_PER_SEC / HZ) * (100 * HZ / 1000) (1000 / 300) * (100 * 300 / 1000) 3 * 30 = 90 This can be easily fixed by reversing the order of the multiplication and division.

[PATCH OLK-6.6] sched: disable sched_autogroup by default
by Zhang Qiao 26 Apr '24

26 Apr '24

From: Jialin Zhang <zhangjialin11(a)huawei.com> hulk inclusion category: performance bugzilla: https://gitee.com/openeuler/kernel/issues/I9JZXF CVE: NA -------------------------------- This option optimizes the scheduler for common desktop workloads by automatically creating and populating task groups. This separation of workloads isolates aggressive CPU burners (like build jobs) from desktop applications. Task group autogeneration is currently based upon task session. We do not need this for mostly server workloads, so just disable by default. If you need this feature really, just enable it by sysctl: sysctl -w kernel.sched_autogroup_enabled=1 Signed-off-by: Jialin Zhang <zhangjialin11(a)huawei.com> Reviewed-by: Xie XiuQi <xiexiuqi(a)huawei.com> Signed-off-by: Zheng Zengkai <zhengzengkai(a)huawei.com> Signed-off-by: Zhang Qiao <zhangqiao22(a)huawei.com> --- kernel/sched/autogroup.c | 2 +- 1 file changed, 1 insertion(+), 1 deletion(-) diff --git a/kernel/sched/autogroup.c b/kernel/sched/autogroup.c index 991fc9002535..e2c2d4e5735f 100644 --- a/kernel/sched/autogroup.c +++ b/kernel/sched/autogroup.c @@ -4,7 +4,7 @@ * Auto-group scheduling implementation: */ -unsigned int __read_mostly sysctl_sched_autogroup_enabled = 1; +unsigned int __read_mostly sysctl_sched_autogroup_enabled; static struct autogroup autogroup_default; static atomic_t autogroup_seq_nr; -- 2.18.0.huawei.25

[PATCH openEuler-1.0-LTS] net/ipv6: avoid possible UAF in ip6_route_mpath_notify()
by Ziyang Xuan 26 Apr '24

26 Apr '24

From: Eric Dumazet <edumazet(a)google.com> stable inclusion from stable-v4.19.310 commit 31ea5bcc7d4cd1423de6be327a2c034725704136 category: bugfix bugzilla: https://gitee.com/src-openeuler/kernel/issues/I9HK9R CVE: CVE-2024-26852 -------------------------------- [ Upstream commit 685f7d531264599b3f167f1e94bbd22f120e5fab ] syzbot found another use-after-free in ip6_route_mpath_notify() [1] Commit f7225172f25a ("net/ipv6: prevent use after free in ip6_route_mpath_notify") was not able to fix the root cause. We need to defer the fib6_info_release() calls after ip6_route_mpath_notify(), in the cleanup phase.

26 Apr '24

From: Eric Dumazet <edumazet(a)google.com> stable inclusion from stable-v4.19.310 commit e431c3227864b5646601c97f5f898d99472f2914 category: bugfix bugzilla: https://gitee.com/src-openeuler/kernel/issues/I9HK9B CVE: CVE-2024-26857 -------------------------------- [ Upstream commit 1ca1ba465e55b9460e4e75dec9fff31e708fec74 ] syzbot triggered a bug in geneve_rx() [1] Issue is similar to the one I fixed in commit 8d975c15c0cd ("ip6_tunnel: make sure to pull inner header in __ip6_tnl_rcv()") We have to save skb->network_header in a temporary variable in order to be able to recompute the network_header pointer after a pskb_inet_may_pull() call. pskb_inet_may_pull() makes sure the needed headers are in skb->head.

[PATCH openEuler-1.0-LTS v3] x86/hyperv: Fix NULL deref in set_hv_tscchange_cb() if Hyper-V setup fails
by Yu Liao 26 Apr '24

26 Apr '24

From: Sean Christopherson <seanjc(a)google.com> stable inclusion from stable-v4.19.218 commit b20ec58f8a6f4fef32cc71480ddf824584e24743 category: bugfix bugzilla: https://gitee.com/src-openeuler/kernel/issues/I9FNFO CVE: CVE-2021-47217 Reference: https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git/commit/?id… -------------------------------- commit daf972118c517b91f74ff1731417feb4270625a4 upstream. Check for a valid hv_vp_index array prior to derefencing hv_vp_index when setting Hyper-V's TSC change callback. If Hyper-V setup failed in hyperv_init(), the kernel will still report that it's running under Hyper-V, but will have silently disabled nearly all functionality.
