[PATCH OLK-6.6 0/1] sched: migtate user interface from smart grid to sched bpf
by Liao Chen 05 Feb '24

05 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 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.

In some scenarios where we need attach task bind to isolated CPUs in task_group, the same problem will occur. Isolated CPUs and non-isolate CPUs are not in the same root_domain. and the hrtimer only check the cpumask of this_rq's root_domain. so when the handler of RT_BANDWIDTH hrtimer is running on the isolated CPU, it will leaved the non-isolated CPUs indefinitely throttled.

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

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.

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.

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] 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. The KASAN report is as follows: ================================================================== BUG: KASAN: global-out-of-bounds in insert_header+0x4b/0x2b0 Read of size 4 at addr ffffffff99c03a58 by task swapper/0/1 Call Trace: <TASK> dump_stack_lvl+0x37/0x50 print_address_description.constprop.0+0x6b/0x3d0 ? insert_header+0x4b/0x2b0 print_report+0xb5/0x270 ? kasan_addr_to_slab+0xd/0xa0 kasan_report+0xb0/0xe0 ? insert_header+0x4b/0x2b0 insert_header+0x4b/0x2b0 __register_sysctl_table+0x1d3/0x220 __register_sysctl_init+0x24/0x50 mem_cgroup_init+0x1cd/0x1e0 ? __pfx_mem_cgroup_init+0x10/0x10 do_one_initcall+0x8e/0x320 ? __pfx_do_one_initcall+0x10/0x10 ? __pfx_parse_args+0x10/0x10 ? __kmem_cache_alloc_node+0x1e0/0x480 ? kasan_set_track+0x25/0x30 ? __kasan_kmalloc+0x7f/0x90 do_initcalls+0xe0/0x1b0 kernel_init_freeable+0x242/0x320 ? __pfx_kernel_init+0x10/0x10 kernel_init+0x1f/0x1e0 ? calculate_sigpending+0x63/0x70 ret_from_fork+0x34/0x60 ? __pfx_kernel_init+0x10/0x10 ret_from_fork_asm+0x1b/0x30 </TASK> The buggy address belongs to the variable: mem_cgroup_sysctls+0x18/0x20 The buggy address belongs to the physical page: Memory state around the buggy address: ffffffff99c03900: 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 ffffffff99c03980: 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 >ffffffff99c03a00: f9 f9 f9 f9 f9 f9 f9 f9 f9 f9 f9 f9 00 00 f9 f9 ^ ffffffff99c03a80: f9 f9 f9 f9 04 f9 f9 f9 f9 f9 f9 f9 00 f9 f9 f9 ffffffff99c03b00: f9 f9 f9 f9 04 f9 f9 f9 f9 f9 f9 f9 04 f9 f9 f9 ================================================================== To fix it, check if mem_cgroup_sysctls is a empty array before calling register_sysctl_init().

[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. Strictly speaking this isn't required for blocking commits and TEST_ONLY calls, but it's the simpler approach. Thanks to shanzhulig for the initial idea of grabbing an unconditional reference, I just added comments, a condensed commit message and fixed a minor potential issue in where exactly we drop the final reference.

[PATCH openEuler-1.0-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-v4.19.291 commit 73a82b22963defa87204f0f9f44a534adf7f831a 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. Thanks to shanzhulig for the initial idea of grabbing an unconditional reference, I just added comments, a condensed commit message and fixed a minor potential issue in where exactly we drop the final reference.

[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

[PATCH OLK-6.6 0/6] 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. v5: - fixed another refcnt bug spotted by Vlastimil - small refactoring of current_obj_cgroup() - added a patch for get_obj_cgroup() refactoring v4: - fixed a bug spotted by Vlastimil - cosmetic changes, per Vlastimil v3: - fixed a bug spotted by Shakeel - added some comments, per Shakeel v2: - fixed a bug discovered by Naresh Kamboju - code changes asked by Johannes (added comments, open-coded bit ops) - merged in a couple of small fixes v1: - made the objcg update fully lockless - fixed !CONFIG_MMU build issues rfc: https://lwn.net/Articles/945722/ -- [1]: static int memory_alloc_test(struct seq_file *m, void *v) { unsigned long i, j; void **ptrs; ktime_t start, end; s64 delta, min_delta = LLONG_MAX; ptrs = kvmalloc(sizeof(void *) * 1000000, GFP_KERNEL); if (!ptrs) return -ENOMEM; for (j = 0; j < 100; j++) { start = ktime_get(); for (i = 0; i < 1000000; i++) ptrs[i] = kmalloc(64, GFP_KERNEL_ACCOUNT); end = ktime_get(); delta = ktime_us_delta(end, start); if (delta < min_delta) min_delta = delta; for (i = 0; i < 1000000; i++) kfree(ptrs[i]); } kvfree(ptrs); seq_printf(m, "%lld us\n", min_delta); return 0; } -- Signed-off-by: Roman Gushchin (Cruise) <roman.gushchin(a)linux.dev> Roman Gushchin (6): 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() 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

[PATCH openEuler-1.0-LTS] block: fix memleak of bio integrity data

From: Justin Tee <justin.tee(a)broadcom.com> mainline inclusion from mainline-v5.5-rc1 commit ece841abbed2da71fa10710c687c9ce9efb6bf69 category: bugfix bugzilla: https://gitee.com/openeuler/kernel/issues/I8ZZ4S CVE: NA Reference: https://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git/commit/?… -------------------------------- 7c20f11680a4 ("bio-integrity: stop abusing bi_end_io") moves bio_integrity_free from bio_uninit() to bio_integrity_verify_fn() and bio_endio(). This way looks wrong because bio may be freed without calling bio_endio(), for example, blk_rq_unprep_clone() is called from dm_mq_queue_rq() when the underlying queue of dm-mpath is busy. So memory leak of bio integrity data is caused by commit 7c20f11680a4. Fixes this issue by re-adding bio_integrity_free() to bio_uninit().

[PATCH openEuler-1.0-LTS 1/2] net: prevent rewrite of msg_name in sock_sendmsg()
by Liu Jian 01 Feb '24

01 Feb '24

From: Jordan Rife <jrife(a)google.com> stable inclusion from stable-v4.19.297 commit 3d62f2577c7414e5b94e4baad6eb621165960f30 category: bugfix bugzilla: https://gitee.com/openeuler/kernel/issues/I90DDU CVE: NA Reference: https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git/commit/?id… --------------------------- [ Upstream commit 86a7e0b69bd5b812e48a20c66c2161744f3caa16 ] Callers of sock_sendmsg(), and similarly kernel_sendmsg(), in kernel space may observe their value of msg_name change in cases where BPF sendmsg hooks rewrite the send address. This has been confirmed to break NFS mounts running in UDP mode and has the potential to break other systems. This patch: 1) Creates a new function called __sock_sendmsg() with same logic as the old sock_sendmsg() function. 2) Replaces calls to sock_sendmsg() made by __sys_sendto() and __sys_sendmsg() with __sock_sendmsg() to avoid an unnecessary copy, as these system calls are already protected. 3) Modifies sock_sendmsg() so that it makes a copy of msg_name if present before passing it down the stack to insulate callers from changes to the send address.

[PATCH openEuler-1.0-LTS] tracing/kprobes: Do the notrace functions check without kprobes on ftrace
by Liu Chuang 31 Jan '24

31 Jan '24

From: Masami Hiramatsu <mhiramat(a)kernel.org> stable inclusion from stable-v4.19.169 commit 4ec3187d17c6915f02e40b2c7b1f41d0fdda1eb4 category: bugfix bugzilla: https://gitee.com/openeuler/kernel/issues/I9093Z CVE: NA Reference: https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git/commit/?id… -------------------------------- commit 7bb83f6fc4ee84e95d0ac0d14452c2619fb3fe70 upstream. Enable the notrace function check on the architecture which doesn't support kprobes on ftrace but support dynamic ftrace. This notrace function check is not only for the kprobes on ftrace but also sw-breakpoint based kprobes. Thus there is no reason to limit this check for the arch which supports kprobes on ftrace. This also changes the dependency of Kconfig. Because kprobe event uses the function tracer's address list for identifying notrace function, if the CONFIG_DYNAMIC_FTRACE=n, it can not check whether the target function is notrace or not.

[PATCH openEuler-1.0-LTS] mm/filemap: avoid buffered read/write race to read inconsistent data

Hence adding the missing read memory barrier to fix this. This is a Load-Load reordering issue, which only occurs on some weak mem-ordering architectures (e.g. ARM64, ALPHA), but not on strong mem-ordering architectures (e.g. X86). And theoretically the problem doesn't only happen on ext4, filesystems that call filemap_read() but don't hold inode lock (e.g. btrfs, f2fs, ubifs ...) will have this problem, while filesystems with inode lock (e.g. xfs, nfs) won't have this problem.

[PATCH OLK-6.6] ubifs: Queue up space reservation tasks if retrying many times

There are 2 empty LEBs used for index nodes, which is calculated as min_idx_lebs - idx_lebs = 2. In theory, LEB 15 and 33 should be reclaimed as free state after committing, but it is now in taken state. After looking the realization of reserve_space(), there's a possible situation: LEB 15: free 2000 dirty 248000 used 3952 (jhead 2) LEB 23: free 2000 dirty 248104 used 3848 (bud, taken) LEB 33: free 2000 dirty 251952 used 0 (bud, taken) wb_workfn wb_workfn_2 do_writepage // write 3000 bytes ubifs_jnl_write_data make_reservation reserve_space ubifs_garbage_collect ubifs_find_dirty_leb // ret ENOSPC, dirty LEBs are taken nospc_retries++ // 1 ubifs_run_commit do_commit LEB 15: free 2000 dirty 248000 used 3952 (jhead 2) LEB 23: free 2000 dirty 248104 used 3848 (dirty) LEB 33: free 2000 dirty 251952 used 0 (dirty) do_writepage // write 2000 bytes for 3 times ubifs_jnl_write_data // grabs 15\23\33 LEB 15: free 0 dirty 248000 used 5952 (bud, taken) LEB 23: free 0 dirty 248104 used 5848 (jhead 2) LEB 33: free 0 dirty 253952 used 0 (bud, taken) reserve_space ubifs_garbage_collect ubifs_find_dirty_leb // ret ENOSPC, dirty LEBs are taken if (nospc_retries++ < 2) // false ubifs_ro_mode ! Fetch a reproducer in Link. The dirty LEBs could be grabbed by other threads, which fails finding dirty LEBs of GC in current thread, so make_reservation() could try many times to invoke GC&&committing, but current realization limits the times of retrying as 'nospc_retries'(twice). Fix it by adding a wait queue, start queuing up space reservation tasks when someone task has retried gc + commit for many times. Then there is only one task making space reservation at any time, and it can always make success under the premise of correct budgeting.

[PATCH openEuler-1.0-LTS] net/sched: sch_hfsc: upgrade 'rt' to 'sc' when it becomes a inner curve
by Zhengchao Shao 31 Jan '24

31 Jan '24

From: Pedro Tammela <pctammela(a)mojatatu.com> stable inclusion from stable-v4.19.297 commit a39a303c06dffaf851e418d814808f5eae669de2 category: bugfix bugzilla: https://gitee.com/openeuler/kernel/issues/I902AI CVE: NA Reference: https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git/commit/?id… -------------------------------- commit a13b67c9a015c4e21601ef9aa4ec9c5d972df1b4 upstream. Christian Theune says: I upgraded from 6.1.38 to 6.1.55 this morning and it broke my traffic shaping script, leaving me with a non-functional uplink on a remote router. A 'rt' curve cannot be used as a inner curve (parent class), but we were allowing such configurations since the qdisc was introduced. Such configurations would trigger a UAF as Budimir explains: The parent will have vttree_insert() called on it in init_vf(), but will not have vttree_remove() called on it in update_vf() because it does not have the HFSC_FSC flag set. The qdisc always assumes that inner classes have the HFSC_FSC flag set. This is by design as it doesn't make sense 'qdisc wise' for an 'rt' curve to be an inner curve. Budimir's original patch disallows users to add classes with a 'rt' parent, but this is too strict as it breaks users that have been using 'rt' as a inner class. Another approach, taken by this patch, is to upgrade the inner 'rt' into a 'sc', warning the user in the process. It avoids the UAF reported by Budimir while also being more permissive to bad scripts/users/code using 'rt' as a inner class. Users checking the `tc class ls [...]` or `tc class get [...]` dumps would observe the curve change and are potentially breaking with this change. v1->v2: https://lore.kernel.org/all/20231013151057.2611860-1-pctammela@mojatatu.com/ - Correct 'Fixes' tag and merge with revert (Jakub) Cc: Christian Theune <ct(a)flyingcircus.io> Cc: Budimir Markovic <markovicbudimir(a)gmail.com> Fixes: b3d26c5702c7 ("net/sched: sch_hfsc: Ensure inner classes have fsc curve") Signed-off-by: Pedro Tammela <pctammela(a)mojatatu.com> Acked-by: Jamal Hadi Salim <jhs(a)mojatatu.com> Link: https://lore.kernel.org/r/20231017143602.3191556-1-pctammela@mojatatu.com Signed-off-by: Jakub Kicinski <kuba(a)kernel.org> Signed-off-by: Greg Kroah-Hartman <gregkh(a)linuxfoundation.org> Signed-off-by: Zhengchao Shao <shaozhengchao(a)huawei.com> --- net/sched/sch_hfsc.c | 18 ++++++++++++++---- 1 file changed, 14 insertions(+), 4 deletions(-) diff --git a/net/sched/sch_hfsc.c b/net/sched/sch_hfsc.c index 60e71a4ce0af..bb9b42002708 100644 --- a/net/sched/sch_hfsc.c +++ b/net/sched/sch_hfsc.c @@ -913,6 +913,14 @@ hfsc_change_usc(struct hfsc_class *cl, struct tc_service_curve *usc, cl->cl_flags |= HFSC_USC; } +static void +hfsc_upgrade_rt(struct hfsc_class *cl) +{ + cl->cl_fsc = cl->cl_rsc; + rtsc_init(&cl->cl_virtual, &cl->cl_fsc, cl->cl_vt, cl->cl_total); + cl->cl_flags |= HFSC_FSC; +} + static const struct nla_policy hfsc_policy[TCA_HFSC_MAX + 1] = { [TCA_HFSC_RSC] = { .len = sizeof(struct tc_service_curve) }, [TCA_HFSC_FSC] = { .len = sizeof(struct tc_service_curve) }, @@ -1021,10 +1029,6 @@ hfsc_change_class(struct Qdisc *sch, u32 classid, u32 parentid, if (parent == NULL) return -ENOENT; } - if (!(parent->cl_flags & HFSC_FSC) && parent != &q->root) { - NL_SET_ERR_MSG(extack, "Invalid parent - parent class must have FSC"); - return -EINVAL; - } if (classid == 0 || TC_H_MAJ(classid ^ sch->handle) != 0) return -EINVAL; @@ -1077,6 +1081,12 @@ hfsc_change_class(struct Qdisc *sch, u32 classid, u32 parentid, cl->cf_tree = RB_ROOT; sch_tree_lock(sch); + /* Check if the inner class is a misconfigured 'rt' */ + if (!(parent->cl_flags & HFSC_FSC) && parent != &q->root) { + NL_SET_ERR_MSG(extack, + "Forced curve change on parent 'rt' to 'sc'"); + hfsc_upgrade_rt(parent); + } qdisc_class_hash_insert(&q->clhash, &cl->cl_common); list_add_tail(&cl->siblings, &parent->children); if (parent->level == 0) -- 2.34.1

'pci_stop_and_remove_bus_device_locked()' will be called. This function will get the global mutex lock 'pci_rescan_remove_lock', and remove the slot. If the irq thread 'pciehp_ist' is still running, we will wait until it exits. If a pciehp interrupt happens immediately after we remove the slot by sysfs, but before we free the pciehp irq in 'pci_stop_and_remove_bus_device_locked()'. 'pciehp_ist' will hung because the global mutex lock 'pci_rescan_remove_lock' is held by the sysfs operation. But the sysfs operation is waiting for the pciehp irq thread 'pciehp_ist' ends. Then a hung task occurs. So this two kinds of operation, removing through attention buttion and removing through /sys/devices/pci***/remove, should not be excuted at the same time. This patch add a global variable to mark that one of these operations is under processing. When this variable is set, if another operation is requested, it will be rejected. We use a global variable 'slot_being_removed_rescaned' to mark whether a slot is being removed or rescaned. This will cause a slot hotplug operation is delayed if another slot is being remove or rescaned. But if these two slots are under different root ports, they should not influence each other. This patch make the flag 'slot_being_removed_rescanned' per root port so that one slot hotplug operation doesn't influence slots below another root port. We record the root port in struct pci_dev when the pci device is initialized and added into the system instead of using 'pcie_find_root_port()' to find the root port when we need it. Because iterating the pci tree needs the protection of 'pci_lock_rescan_remove()'. This will make the problem more complexed because the lock is very coarse-grained. We don't need to worry about 'use-after-free' because child pci devices are always removed before the root port device is removed.
