[PATCH openEuler-1.0-LTS v2] xen-netback: don't produce zero-size SKB frags
by Ziyang Xuan 20 Feb '24

From: Jan Beulich <jbeulich(a)suse.com> stable inclusion from stable-v4.19.306 commit 5bb8270789c88c0e4ad78c0de2f274f2275c7f6c category: bugfix bugzilla: https://gitee.com/src-openeuler/kernel/issues/I8YCSC CVE: CVE-2023-46838 Reference: https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git/commit/?id… -------------------------------- commit c7ec4f2d684e17d69bbdd7c4324db0ef5daac26a upstream. While frontends may submit zero-size requests (wasting a precious slot), core networking code as of at least 3ece782693c4b ("sock: skb_copy_ubufs support for compound pages") can't deal with SKBs when they have all zero-size fragments. Respond to empty requests right when populating fragments; all further processing is fragment based and hence won't encounter these empty requests anymore. In a way this should have been that way from the beginning: When no data is to be transferred for a particular request, there's not even a point in validating the respective grant ref. That's no different from e.g. passing NULL into memcpy() when at the same time the size is 0. This is XSA-448 / CVE-2023-46838.

[PATCH openEuler-1.0-LTS] tty: fix return value for unsupported ioctls
by Yi Yang 19 Feb '24

19 Feb '24

From: Johan Hovold <johan(a)kernel.org> stable inclusion from stable-v4.19.191 commit 76d7fc0857bc4033415fcad905db13753d0febc7 category: bugfix bugzilla: https://gitee.com/openeuler/kernel/issues/I926JG CVE: NA Reference: https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git/commit/?id… -------------------------------- [ Upstream commit 1b8b20868a6d64cfe8174a21b25b74367bdf0560 ] Drivers should return -ENOTTY ("Inappropriate I/O control operation") when an ioctl isn't supported, while -EINVAL is used for invalid arguments. Fix up the TIOCMGET, TIOCMSET and TIOCGICOUNT helpers which returned -EINVAL when a tty driver did not implement the corresponding operations. Note that the TIOCMGET and TIOCMSET helpers predate git and do not get a corresponding Fixes tag below.

[PATCH OLK-6.6] fs,hugetlb: fix NULL pointer dereference in hugetlbs_fill_super
by Liu Shixin 19 Feb '24

19 Feb '24

From: Oscar Salvador <osalvador(a)suse.de> mainline inclusion from mainline-v6.8-rc4 commit 79d72c68c58784a3e1cd2378669d51bfd0cb7498 category: bugfix bugzilla: https://gitee.com/src-openeuler/kernel/issues/I8ZGZK CVE: CVE-2024-0841 Reference: https://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git/commit/?… -------------------------------- When configuring a hugetlb filesystem via the fsconfig() syscall, there is a possible NULL dereference in hugetlbfs_fill_super() caused by assigning NULL to ctx->hstate in hugetlbfs_parse_param() when the requested pagesize is non valid. E.g: Taking the following steps: fd = fsopen("hugetlbfs", FSOPEN_CLOEXEC); fsconfig(fd, FSCONFIG_SET_STRING, "pagesize", "1024", 0); fsconfig(fd, FSCONFIG_CMD_CREATE, NULL, NULL, 0); Given that the requested "pagesize" is invalid, ctxt->hstate will be replaced with NULL, losing its previous value, and we will print an error: ... ... case Opt_pagesize: ps = memparse(param->string, &rest); ctx->hstate = h; if (!ctx->hstate) { pr_err("Unsupported page size %lu MB\n", ps / SZ_1M); return -EINVAL; } return 0; ... ... This is a problem because later on, we will dereference ctxt->hstate in hugetlbfs_fill_super() ... ... sb->s_blocksize = huge_page_size(ctx->hstate); ... ... Causing below Oops. Fix this by replacing cxt->hstate value only when then pagesize is known to be valid. kernel: hugetlbfs: Unsupported page size 0 MB kernel: BUG: kernel NULL pointer dereference, address: 0000000000000028 kernel: #PF: supervisor read access in kernel mode kernel: #PF: error_code(0x0000) - not-present page kernel: PGD 800000010f66c067 P4D 800000010f66c067 PUD 1b22f8067 PMD 0 kernel: Oops: 0000 [#1] PREEMPT SMP PTI kernel: CPU: 4 PID: 5659 Comm: syscall Tainted: G E 6.8.0-rc2-default+ #22 5a47c3fef76212addcc6eb71344aabc35190ae8f kernel: Hardware name: Intel Corp.

[PATCH OLK-5.10] fs,hugetlb: fix NULL pointer dereference in hugetlbs_fill_super
by Liu Shixin 19 Feb '24

19 Feb '24

From: Oscar Salvador <osalvador(a)suse.de> mainline inclusion from mainline-v6.8-rc4 commit 79d72c68c58784a3e1cd2378669d51bfd0cb7498 category: bugfix bugzilla: https://gitee.com/src-openeuler/kernel/issues/I8ZGZK CVE: CVE-2024-0841 Reference: https://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git/commit/?… -------------------------------- When configuring a hugetlb filesystem via the fsconfig() syscall, there is a possible NULL dereference in hugetlbfs_fill_super() caused by assigning NULL to ctx->hstate in hugetlbfs_parse_param() when the requested pagesize is non valid. E.g: Taking the following steps: fd = fsopen("hugetlbfs", FSOPEN_CLOEXEC); fsconfig(fd, FSCONFIG_SET_STRING, "pagesize", "1024", 0); fsconfig(fd, FSCONFIG_CMD_CREATE, NULL, NULL, 0); Given that the requested "pagesize" is invalid, ctxt->hstate will be replaced with NULL, losing its previous value, and we will print an error: ... ... case Opt_pagesize: ps = memparse(param->string, &rest); ctx->hstate = h; if (!ctx->hstate) { pr_err("Unsupported page size %lu MB\n", ps / SZ_1M); return -EINVAL; } return 0; ... ... This is a problem because later on, we will dereference ctxt->hstate in hugetlbfs_fill_super() ... ... sb->s_blocksize = huge_page_size(ctx->hstate); ... ... Causing below Oops. Fix this by replacing cxt->hstate value only when then pagesize is known to be valid. kernel: hugetlbfs: Unsupported page size 0 MB kernel: BUG: kernel NULL pointer dereference, address: 0000000000000028 kernel: #PF: supervisor read access in kernel mode kernel: #PF: error_code(0x0000) - not-present page kernel: PGD 800000010f66c067 P4D 800000010f66c067 PUD 1b22f8067 PMD 0 kernel: Oops: 0000 [#1] PREEMPT SMP PTI kernel: CPU: 4 PID: 5659 Comm: syscall Tainted: G E 6.8.0-rc2-default+ #22 5a47c3fef76212addcc6eb71344aabc35190ae8f kernel: Hardware name: Intel Corp.

[PATCH OLK-6.6 0/1] sched: migtate user interface from smart grid to sched bpf
by Liao Chen 07 Feb '24

Migtating user interface from smart grid to sched bpf, which allows users to set SCHED_GRID_QOS_TASK_LEVEL through: /proc/${pid}/task/${pid}/tag interface. Although arbitrary integer value could be assigned to <tag>, currnetly we clamp the value of SCHED_GRID_QOS_TASK_LEVEL to 0-7, which maintains consistency.

[PATCH openEuler-1.0-LTS] xen-netback: don't produce zero-size SKB frags
by Ziyang Xuan 06 Feb '24

06 Feb '24

From: Jan Beulich <jbeulich(a)suse.com> stable inclusion from stable-v5.10.209 commit 5bb8270789c88c0e4ad78c0de2f274f2275c7f6c category: bugfix bugzilla: https://gitee.com/src-openeuler/kernel/issues/I8YCSC CVE: CVE-2023-46838 Reference: https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git/commit/?id… -------------------------------- commit c7ec4f2d684e17d69bbdd7c4324db0ef5daac26a upstream. While frontends may submit zero-size requests (wasting a precious slot), core networking code as of at least 3ece782693c4b ("sock: skb_copy_ubufs support for compound pages") can't deal with SKBs when they have all zero-size fragments. Respond to empty requests right when populating fragments; all further processing is fragment based and hence won't encounter these empty requests anymore. In a way this should have been that way from the beginning: When no data is to be transferred for a particular request, there's not even a point in validating the respective grant ref. That's no different from e.g. passing NULL into memcpy() when at the same time the size is 0. This is XSA-448 / CVE-2023-46838.

Migtating user interface from smart grid to sched bpf, which allows users to set SCHED_GRID_QOS_TASK_LEVEL through: /proc/${pid}/task/${pid}/tag interface. Although arbitrary integer value could be assigned to <tag>, currnetly we clamp the value of SCHED_GRID_QOS_TASK_LEVEL to 0-7, which maintains consistency.

[PATCH OLK-6.6] sched/deadline.c: pick and check task if double_lock_balance() unlock the rq
by Zhao Wenhui 05 Feb '24

05 Feb '24

From: Li Bin <huawei.libin(a)huawei.com> hulk inclusion category: bugfix bugzilla: 47435 CVE: NA --------------------------- push_dl_task() pick the first pushable task and find an eligible lowest_rq, then double_lock_balance(rq, lowest_rq). So if double_lock_balance() unlock the rq (when double_lock_balance() return 1), we have to check if this task is still on the rq. The problem is that the check conditions are not sufficient: if (unlikely(task_rq(task) != rq || !cpumask_test_cpu(later_rq->cpu, &task->cpus_allowed) || task_running(rq, task) || !dl_task(task) || !task_on_rq_queued(task))) { cpu2 cpu1 cpu0 push_dl_task(rq1) pick task_A on rq1 find rq0 double_lock_balance(rq1, rq0) unlock(rq1) rq1 __schedule pick task_A run task_A sleep (dequeued) lock(rq0) lock(rq1) do_above_check(task_A) task_rq(task_A) == rq1 cpus_allowed unchanged task_running == false dl_task(task_A) == true try_to_wake_up(task_A) select_cpu = cpu3 enqueue(rq3, task_A) task_A->on_rq = 1 task_on_rq_queued(task_A) above_check passed, return rq0 ... migrate task_A from rq1 to rq0 So we can't rely on these checks of task_A to make sure the task_A is still on the rq1, even though we hold the rq1->lock. This patch will repick the first pushable task to be sure the task is still on the rq.

Migtating user interface from smart grid to sched bpf, which allows users to set SCHED_GRID_QOS_TASK_LEVEL through: /proc/${pid}/task/${pid}/tag interface. Although arbitrary integer value could be assigned to <tag>, currnetly we clamp the value of SCHED_GRID_QOS_TASK_LEVEL to 0-7, which maintains consistency.

[PATCH OLK-6.6] sched/rt.c: pick and check task if double_lock_balance() unlock the rq
by Zhao Wenhui 05 Feb '24

05 Feb '24

From: Zhou Chengming <zhouchengming1(a)huawei.com> hulk inclusion category: bugfix bugzilla: 47435 CVE: NA --------------------------- push_rt_task() pick the first pushable task and find an eligible lowest_rq, then double_lock_balance(rq, lowest_rq). So if double_lock_balance() unlock the rq (when double_lock_balance() return 1), we have to check if this task is still on the rq. The problem is that the check conditions are not sufficient: if (unlikely(task_rq(task) != rq || !cpumask_test_cpu(lowest_rq->cpu, &task->cpus_allowed) || task_running(rq, task) || !rt_task(task) || !task_on_rq_queued(task))) { cpu2 cpu1 cpu0 push_rt_task(rq1) pick task_A on rq1 find rq0 double_lock_balance(rq1, rq0) unlock(rq1) rq1 __schedule pick task_A run task_A sleep (dequeued) lock(rq0) lock(rq1) do_above_check(task_A) task_rq(task_A) == rq1 cpus_allowed unchanged task_running == false rt_task(task_A) == true try_to_wake_up(task_A) select_cpu = cpu3 enqueue(rq3, task_A) task_A->on_rq = 1 task_on_rq_queued(task_A) above_check passed, return rq0 ... migrate task_A from rq1 to rq0 So we can't rely on these checks of task_A to make sure the task_A is still on the rq1, even though we hold the rq1->lock. This patch will repick the first pushable task to be sure the task is still on the rq.

[PATCH OLK-6.6] mm/memcontrol: fix out-of-bound access in mem_cgroup_sysctls_init
by Jinjiang Tu 05 Feb '24

hulk inclusion category: bugfix bugzilla: https://gitee.com/openeuler/kernel/issues/I90E0C CVE: NA -------------------------------- Patchset[1] supports to remove the sentinel element in the ctl_table when registering it to sysctl. However, the patchset fails to handle when the array is empty, leading to out-of-bound access in insert_header. When CONFIG_MEMCG_OOM_PRIORITY and CONFIG_MEMCG_SWAP_QOS are disabled, mem_cgroup_sysctls is a empty array, mem_cgroup_sysctls_init() calls register_sysctl_init() to register it. This leads to out-of-bound access.
