[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.
