The patch titled Subject: memcontrol: ensure memcg acquired by id is properly set up has been added to the -mm mm-hotfixes-unstable branch. Its filename is memcontrol-ensure-memcg-acquired-by-id-is-properly-set-up.patch This patch will shortly appear at https://git.kernel.org/pub/scm/linux/kernel/git/akpm/25-new.git/tree/patche… This patch will later appear in the mm-hotfixes-unstable branch at git://git.kernel.org/pub/scm/linux/kernel/git/akpm/mm Before you just go and hit "reply", please: a) Consider who else should be cc'ed b) Prefer to cc a suitable mailing list as well c) Ideally: find the original patch on the mailing list and do a reply-to-all to that, adding suitable additional cc's *** Remember to use Documentation/process/submit-checklist.rst when testing your code *** The -mm tree is included into linux-next via the mm-everything branch at git://git.kernel.org/pub/scm/linux/kernel/git/akpm/mm and is updated there every 2-3 working days ------------------------------------------------------ From: Johannes Weiner <hannes(a)cmpxchg.org> Subject: memcontrol: ensure memcg acquired by id is properly set up Date: Wed, 23 Aug 2023 15:54:30 -0700 In the eviction recency check, we attempt to retrieve the memcg to which the folio belonged when it was evicted, by the memcg id stored in the shadow entry. However, there is a chance that the retrieved memcg is not the original memcg that has been killed, but a new one which happens to have the same id. This is a somewhat unfortunate, but acceptable and rare inaccuracy in the heuristics. However, if we retrieve this new memcg between its allocation and when it is properly attached to the memcg hierarchy, we could run into the following NULL pointer exception during the memcg hierarchy traversal done in mem_cgroup_get_nr_swap_pages(): [ 155757.793456] BUG: kernel NULL pointer dereference, address: 00000000000000c0 [ 155757.807568] #PF: supervisor read access in kernel mode [ 155757.818024] #PF: error_code(0x0000) - not-present page [ 155757.828482] PGD 401f77067 P4D 401f77067 PUD 401f76067 PMD 0 [ 155757.839985] Oops: 0000 [#1] SMP [ 155757.887870] RIP: 0010:mem_cgroup_get_nr_swap_pages+0x3d/0xb0 [ 155757.899377] Code: 29 19 4a 02 48 39 f9 74 63 48 8b 97 c0 00 00 00 48 8b b7 58 02 00 00 48 2b b7 c0 01 00 00 48 39 f0 48 0f 4d c6 48 39 d1 74 42 <48> 8b b2 c0 00 00 00 48 8b ba 58 02 00 00 48 2b ba c0 01 00 00 48 [ 155757.937125] RSP: 0018:ffffc9002ecdfbc8 EFLAGS: 00010286 [ 155757.947755] RAX: 00000000003a3b1c RBX: 000007ffffffffff RCX: ffff888280183000 [ 155757.962202] RDX: 0000000000000000 RSI: 0007ffffffffffff RDI: ffff888bbc2d1000 [ 155757.976648] RBP: 0000000000000001 R08: 000000000000000b R09: ffff888ad9cedba0 [ 155757.991094] R10: ffffea0039c07900 R11: 0000000000000010 R12: ffff888b23a7b000 [ 155758.005540] R13: 0000000000000000 R14: ffff888bbc2d1000 R15: 000007ffffc71354 [ 155758.019991] FS: 00007f6234c68640(0000) GS:ffff88903f9c0000(0000) knlGS:0000000000000000 [ 155758.036356] CS: 0010 DS: 0000 ES: 0000 CR0: 0000000080050033 [ 155758.048023] CR2: 00000000000000c0 CR3: 0000000a83eb8004 CR4: 00000000007706e0 [ 155758.062473] DR0: 0000000000000000 DR1: 0000000000000000 DR2: 0000000000000000 [ 155758.076924] DR3: 0000000000000000 DR6: 00000000fffe0ff0 DR7: 0000000000000400 [ 155758.091376] PKRU: 55555554 [ 155758.096957] Call Trace: [ 155758.102016] <TASK> [ 155758.106502] ? __die+0x78/0xc0 [ 155758.112793] ? page_fault_oops+0x286/0x380 [ 155758.121175] ? exc_page_fault+0x5d/0x110 [ 155758.129209] ? asm_exc_page_fault+0x22/0x30 [ 155758.137763] ? mem_cgroup_get_nr_swap_pages+0x3d/0xb0 [ 155758.148060] workingset_test_recent+0xda/0x1b0 [ 155758.157133] workingset_refault+0xca/0x1e0 [ 155758.165508] filemap_add_folio+0x4d/0x70 [ 155758.173538] page_cache_ra_unbounded+0xed/0x190 [ 155758.182919] page_cache_sync_ra+0xd6/0x1e0 [ 155758.191738] filemap_read+0x68d/0xdf0 [ 155758.199495] ? mlx5e_napi_poll+0x123/0x940 [ 155758.207981] ? __napi_schedule+0x55/0x90 [ 155758.216095] __x64_sys_pread64+0x1d6/0x2c0 [ 155758.224601] do_syscall_64+0x3d/0x80 [ 155758.232058] entry_SYSCALL_64_after_hwframe+0x46/0xb0 [ 155758.242473] RIP: 0033:0x7f62c29153b5 [ 155758.249938] Code: e8 48 89 75 f0 89 7d f8 48 89 4d e0 e8 b4 e6 f7 ff 41 89 c0 4c 8b 55 e0 48 8b 55 e8 48 8b 75 f0 8b 7d f8 b8 11 00 00 00 0f 05 <48> 3d 00 f0 ff ff 77 33 44 89 c7 48 89 45 f8 e8 e7 e6 f7 ff 48 8b [ 155758.288005] RSP: 002b:00007f6234c5ffd0 EFLAGS: 00000293 ORIG_RAX: 0000000000000011 [ 155758.303474] RAX: ffffffffffffffda RBX: 00007f628c4e70c0 RCX: 00007f62c29153b5 [ 155758.318075] RDX: 000000000003c041 RSI: 00007f61d2986000 RDI: 0000000000000076 [ 155758.332678] RBP: 00007f6234c5fff0 R08: 0000000000000000 R09: 0000000064d5230c [ 155758.347452] R10: 000000000027d450 R11: 0000000000000293 R12: 000000000003c041 [ 155758.362044] R13: 00007f61d2986000 R14: 00007f629e11b060 R15: 000000000027d450 [ 155758.376661] </TASK> This patch fixes the issue by moving the memcg's id publication from the alloc stage to online stage, ensuring that any memcg acquired via id must be connected to the memcg tree.

I reproduced the error, the combination of gcc-11.1 and binutils 2.37 does cause errors. What a surprise, since binutils 2.36 and 2.38 are fine. I used git bisect to locate this commit[1] for binutils. I'll test this diff in more detail later. Thanks!

[tip: x86/urgent] x86/fpu: Invalidate FPU state correctly on exec()

by tip-bot2 for Rick Edgecombe

The following commit has been merged into the x86/urgent branch of tip: Commit-ID: 1f69383b203e28cf8a4ca9570e572da1699f76cd Gitweb: https://git.kernel.org/tip/1f69383b203e28cf8a4ca9570e572da1699f76cd Author: Rick Edgecombe <rick.p.edgecombe(a)intel.com> AuthorDate: Fri, 18 Aug 2023 10:03:05 -07:00 Committer: Thomas Gleixner <tglx(a)linutronix.de> CommitterDate: Thu, 24 Aug 2023 11:01:45 +02:00 x86/fpu: Invalidate FPU state correctly on exec() The thread flag TIF_NEED_FPU_LOAD indicates that the FPU saved state is valid and should be reloaded when returning to userspace. However, the kernel will skip doing this if the FPU registers are already valid as determined by fpregs_state_valid(). The logic embedded there considers the state valid if two cases are both true: 1: fpu_fpregs_owner_ctx points to the current tasks FPU state 2: the last CPU the registers were live in was the current CPU. This is usually correct logic. A CPU’s fpu_fpregs_owner_ctx is set to the current FPU during the fpregs_restore_userregs() operation, so it indicates that the registers have been restored on this CPU. But this alone doesn’t preclude that the task hasn’t been rescheduled to a different CPU, where the registers were modified, and then back to the current CPU. To verify that this was not the case the logic relies on the second condition. So the assumption is that if the registers have been restored, AND they haven’t had the chance to be modified (by being loaded on another CPU), then they MUST be valid on the current CPU. Besides the lazy FPU optimizations, the other cases where the FPU registers might not be valid are when the kernel modifies the FPU register state or the FPU saved buffer. In this case the operation modifying the FPU state needs to let the kernel know the correspondence has been broken. The comment in “arch/x86/kernel/fpu/context.h” has: /* ... * If the FPU register state is valid, the kernel can skip restoring the * FPU state from memory. * * Any code that clobbers the FPU registers or updates the in-memory * FPU state for a task MUST let the rest of the kernel know that the * FPU registers are no longer valid for this task. * * Either one of these invalidation functions is enough. Invalidate * a resource you control: CPU if using the CPU for something else * (with preemption disabled), FPU for the current task, or a task that * is prevented from running by the current task. */ However, this is not completely true. When the kernel modifies the registers or saved FPU state, it can only rely on __fpu_invalidate_fpregs_state(), which wipes the FPU’s last_cpu tracking. The exec path instead relies on fpregs_deactivate(), which sets the CPU’s FPU context to NULL. This was observed to fail to restore the reset FPU state to the registers when returning to userspace in the following scenario: 1. A task is executing in userspace on CPU0 - CPU0’s FPU context points to tasks - fpu->last_cpu=CPU0 2. The task exec()’s 3. While in the kernel the task is preempted - CPU0 gets a thread executing in the kernel (such that no other FPU context is activated) - Scheduler sets task’s fpu->last_cpu=CPU0 when scheduling out 4. Task is migrated to CPU1 5. Continuing the exec(), the task gets to fpu_flush_thread()->fpu_reset_fpregs() - Sets CPU1’s fpu context to NULL - Copies the init state to the task’s FPU buffer - Sets TIF_NEED_FPU_LOAD on the task 6. The task reschedules back to CPU0 before completing the exec() and returning to userspace - During the reschedule, scheduler finds TIF_NEED_FPU_LOAD is set - Skips saving the registers and updating task’s fpu→last_cpu, because TIF_NEED_FPU_LOAD is the canonical source. 7. Now CPU0’s FPU context is still pointing to the task’s, and fpu->last_cpu is still CPU0. So fpregs_state_valid() returns true even though the reset FPU state has not been restored. So the root cause is that exec() is doing the wrong kind of invalidate. It should reset fpu->last_cpu via __fpu_invalidate_fpregs_state(). Further, fpu__drop() doesn't really seem appropriate as the task (and FPU) are not going away, they are just getting reset as part of an exec. So switch to __fpu_invalidate_fpregs_state(). Also, delete the misleading comment that says that either kind of invalidate will be enough, because it’s not always the case.

[PATCH AUTOSEL 6.4 01/11] idmaengine: make FSL_EDMA and INTEL_IDMA64 depends on HAS_IOMEM

by Sasha Levin

From: Baoquan He <bhe(a)redhat.com> [ Upstream commit b1e213a9e31c20206f111ec664afcf31cbfe0dbb ] On s390 systems (aka mainframes), it has classic channel devices for networking and permanent storage that are currently even more common than PCI devices. Hence it could have a fully functional s390 kernel with CONFIG_PCI=n, then the relevant iomem mapping functions [including ioremap(), devm_ioremap(), etc.] are not available. Here let FSL_EDMA and INTEL_IDMA64 depend on HAS_IOMEM so that it won't be built to cause below compiling error if PCI is unset. -------- ERROR: modpost: "devm_platform_ioremap_resource" [drivers/dma/fsl-edma.ko] undefined!
