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

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.

[PATCH OLK-5.10] netfilter: nf_tables: reject QUEUE/DROP verdict parameters
by Dong Chenchen 04 Feb '24

04 Feb '24

From: Florian Westphal <fw(a)strlen.de> mainline inclusion from mainline-v6.8-rc2 commit f342de4e2f33e0e39165d8639387aa6c19dff660 category: bugfix bugzilla: https://gitee.com/src-openeuler/kernel/issues/I90B2K CVE: CVE-2024-1086 Reference: https://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git/commit/?… -------------------------------- This reverts commit e0abdadcc6e1. core.c:nf_hook_slow assumes that the upper 16 bits of NF_DROP verdicts contain a valid errno, i.e. -EPERM, -EHOSTUNREACH or similar, or 0. Due to the reverted commit, its possible to provide a positive value, e.g. NF_ACCEPT (1), which results in use-after-free. Its not clear to me why this commit was made. NF_QUEUE is not used by nftables; "queue" rules in nftables will result in use of "nft_queue" expression. If we later need to allow specifiying errno values from userspace (do not know why), this has to call NF_DROP_GETERR and check that "err <= 0" holds true.

[PATCH openEuler-1.0-LTS] netfilter: nf_tables: reject QUEUE/DROP verdict parameters
by Dong Chenchen 04 Feb '24

04 Feb '24

From: Florian Westphal <fw(a)strlen.de> mainline inclusion from mainline-v6.8-rc2 commit f342de4e2f33e0e39165d8639387aa6c19dff660 category: bugfix bugzilla: https://gitee.com/src-openeuler/kernel/issues/I90B2K CVE: CVE-2024-1086 Reference: https://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git/commit/?… -------------------------------- This reverts commit e0abdadcc6e1. core.c:nf_hook_slow assumes that the upper 16 bits of NF_DROP verdicts contain a valid errno, i.e. -EPERM, -EHOSTUNREACH or similar, or 0. Due to the reverted commit, its possible to provide a positive value, e.g. NF_ACCEPT (1), which results in use-after-free. Its not clear to me why this commit was made. NF_QUEUE is not used by nftables; "queue" rules in nftables will result in use of "nft_queue" expression. If we later need to allow specifiying errno values from userspace (do not know why), this has to call NF_DROP_GETERR and check that "err <= 0" holds true.

[PATCH OLK-6.6 0/4] memory tiering: calculate abstract distance based on ACPI HMAT
by Tong Tiangen 04 Feb '24

04 Feb '24

We have the explicit memory tiers framework to manage systems with multiple types of memory, e.g., DRAM in DIMM slots and CXL memory devices. Where, same kind of memory devices will be grouped into memory types, then put into memory tiers. To describe the performance of a memory type, abstract distance is defined. Which is in direct proportion to the memory latency and inversely proportional to the memory bandwidth. To keep the code as simple as possible, fixed abstract distance is used in dax/kmem to describe slow memory such as Optane DCPMM. To support more memory types, in this series, we added the abstract distance calculation algorithm management mechanism, provided a algorithm implementation based on ACPI HMAT, and used the general abstract distance calculation interface in dax/kmem driver. So, dax/kmem can support HBM (high bandwidth memory) in addition to the original Optane DCPMM. Huang Ying (4): memory tiering: add abstract distance calculation algorithms management acpi, hmat: refactor hmat_register_target_initiators() acpi, hmat: calculate abstract distance with HMAT dax, kmem: calculate abstract distance with general interface drivers/acpi/numa/hmat.c | 146 ++++++++++++++++++++----------- drivers/dax/kmem.c | 62 ++++++++++--- include/linux/memory-tiers.h | 39 +++++++++ mm/memory-tiers.c | 165 ++++++++++++++++++++++++++++++++++- 4 files changed, 344 insertions(+), 68 deletions(-) -- 2.25.1

[PATCH OLK-6.6 0/4] Introduce page eject for arm64
by Wupeng Ma 04 Feb '24

04 Feb '24

From: Ma Wupeng <mawupeng1(a)huawei.com> Page ejection is achieved by soft_offline_page and unpoison_memory. A linked list is maintained to log the pfns which are offlined by this module. Only the pfns present in the list is allowed to go online. The follow sysfs is introduced to online/offline page via this module, since there is a internal linked list to record all offlined pages, remove_page is introduce to remove this page from list. - /sys/kernel/page_eject/online_page - /sys/kernel/page_eject/offline_page - /sys/kernel/page_eject/remove_page Ma Wupeng (4): mm/hwpoison: Export symbol soft_offline_page mm/memory-failure: introduce soft_online_page mm: page_eject: Introuduce page ejection config: update defconfig for PAGE_EJECT arch/arm64/configs/openeuler_defconfig | 1 + drivers/ras/Kconfig | 10 + drivers/ras/Makefile | 1 + drivers/ras/page_eject.c | 249 +++++++++++++++++++++++++ include/linux/mm.h | 1 + mm/memory-failure.c | 40 ++-- 6 files changed, 288 insertions(+), 14 deletions(-) create mode 100644 drivers/ras/page_eject.c -- 2.25.1

[PATCH OLK-6.6 0/4] memory tiering: calculate abstract distance based on ACPI HMAT
by Tong Tiangen 03 Feb '24

03 Feb '24

We have the explicit memory tiers framework to manage systems with multiple types of memory, e.g., DRAM in DIMM slots and CXL memory devices. Where, same kind of memory devices will be grouped into memory types, then put into memory tiers. To describe the performance of a memory type, abstract distance is defined. Which is in direct proportion to the memory latency and inversely proportional to the memory bandwidth. To keep the code as simple as possible, fixed abstract distance is used in dax/kmem to describe slow memory such as Optane DCPMM. To support more memory types, in this series, we added the abstract distance calculation algorithm management mechanism, provided a algorithm implementation based on ACPI HMAT, and used the general abstract distance calculation interface in dax/kmem driver. So, dax/kmem can support HBM (high bandwidth memory) in addition to the original Optane DCPMM. Huang Ying (4): memory tiering: add abstract distance calculation algorithms management acpi, hmat: refactor hmat_register_target_initiators() acpi, hmat: calculate abstract distance with HMAT dax, kmem: calculate abstract distance with general interface drivers/acpi/numa/hmat.c | 146 ++++++++++++++++++++----------- drivers/dax/kmem.c | 62 ++++++++++--- include/linux/memory-tiers.h | 39 +++++++++ mm/memory-tiers.c | 165 ++++++++++++++++++++++++++++++++++- 4 files changed, 344 insertions(+), 68 deletions(-) -- 2.25.1

[PATCH OLK-6.6] mm/memcontrol: fix out-of-bound access in mem_cgroup_sysctls_init
by Jinjiang Tu 02 Feb '24

02 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.

[PATCH openEuler-22.03-LTS v2] drm/atomic: Fix potential use-after-free in nonblocking commits
by Guo Mengqi 02 Feb '24

02 Feb '24

From: Daniel Vetter <daniel.vetter(a)ffwll.ch> stable inclusion from stable-v5.10.188 commit f09c0ac142c59495262dd80545f261b2aeeba538 category: bugfix bugzilla: https://gitee.com/src-openeuler/kernel/issues/I8YD5O CVE: CVE-2023-51043 Reference: https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git/commit/?id… -------------------------------- commit 4e076c73e4f6e90816b30fcd4a0d7ab365087255 upstream. This requires a bit of background. Properly done a modeset driver's unload/remove sequence should be drm_dev_unplug(); drm_atomic_helper_shutdown(); drm_dev_put(); The trouble is that the drm_dev_unplugged() checks are by design racy, they do not synchronize against all outstanding ioctl. This is because those ioctl could block forever (both for modeset and for driver specific ioctls), leading to deadlocks in hotunplug. Instead the code sections that touch the hardware need to be annotated with drm_dev_enter/exit, to avoid accessing hardware resources after the unload/remove has finished. To avoid use-after-free issues all the involved userspace visible objects are supposed to hold a reference on the underlying drm_device, like drm_file does. The issue now is that we missed one, the atomic modeset ioctl can be run in a nonblocking fashion, and in that case it cannot rely on the implied drm_device reference provided by the ioctl calling context. This can result in a use-after-free if an nonblocking atomic commit is carefully raced against a driver unload. Fix this by unconditionally grabbing a drm_device reference for any drm_atomic_state structures.

[PATCH openEuler-22.03-LTS-SP2 v2] drm/atomic: Fix potential use-after-free in nonblocking commits
by Guo Mengqi 02 Feb '24

02 Feb '24

From: Daniel Vetter <daniel.vetter(a)ffwll.ch> stable inclusion from stable-v5.10.188 commit f09c0ac142c59495262dd80545f261b2aeeba538 category: bugfix bugzilla: https://gitee.com/src-openeuler/kernel/issues/I8YD5O CVE: CVE-2023-51043 Reference: https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git/commit/?id… -------------------------------- commit 4e076c73e4f6e90816b30fcd4a0d7ab365087255 upstream. This requires a bit of background. Properly done a modeset driver's unload/remove sequence should be drm_dev_unplug(); drm_atomic_helper_shutdown(); drm_dev_put(); The trouble is that the drm_dev_unplugged() checks are by design racy, they do not synchronize against all outstanding ioctl. This is because those ioctl could block forever (both for modeset and for driver specific ioctls), leading to deadlocks in hotunplug. Instead the code sections that touch the hardware need to be annotated with drm_dev_enter/exit, to avoid accessing hardware resources after the unload/remove has finished. To avoid use-after-free issues all the involved userspace visible objects are supposed to hold a reference on the underlying drm_device, like drm_file does. The issue now is that we missed one, the atomic modeset ioctl can be run in a nonblocking fashion, and in that case it cannot rely on the implied drm_device reference provided by the ioctl calling context. This can result in a use-after-free if an nonblocking atomic commit is carefully raced against a driver unload. Fix this by unconditionally grabbing a drm_device reference for any drm_atomic_state structures. Strictly speaking this isn't required for blocking commits and TEST_ONLY calls, but it's the simpler approach.

[PATCH OLK-6.6 0/7] mm: improve performance of accounted kernel memory allocations
by Liu Shixin 01 Feb '24

01 Feb '24

This patchset improves the performance of accounted kernel memory allocations by ~30% as measured by a micro-benchmark [1]. The benchmark is very straightforward: 1M of 64 bytes-large kmalloc() allocations. Below are results with the disabled kernel memory accounting, the original state and with this patchset applied. | | Kmem disabled | Original | Patched | Delta | |-------------+---------------+----------+---------+--------| | User cgroup | 29764 | 84548 | 59078 | -30.0% | | Root cgroup | 29742 | 48342 | 31501 | -34.8% | As we can see, the patchset removes the majority of the overhead when there is no actual accounting (a task belongs to the root memory cgroup) and almost halves the accounting overhead otherwise. The main idea is to get rid of unnecessary memcg to objcg conversions and switch to a scope-based protection of objcgs, which eliminates extra operations with objcg reference counters under a rcu read lock. More details are provided in individual commit descriptions. Roman Gushchin (7): mm: kmem: optimize get_obj_cgroup_from_current() mm: kmem: add direct objcg pointer to task_struct mm: kmem: make memcg keep a reference to the original objcg mm: kmem: scoped objcg protection percpu: scoped objcg protection mm: kmem: reimplement get_obj_cgroup_from_current() mm: kmem: properly initialize local objcg variable in current_obj_cgroup() include/linux/memcontrol.h | 28 +++++- include/linux/sched.h | 4 + include/linux/sched/mm.h | 4 + mm/memcontrol.c | 187 +++++++++++++++++++++++++++++++------ mm/percpu.c | 8 +- mm/slab.h | 15 +-- 6 files changed, 204 insertions(+), 42 deletions(-) -- 2.25.1
