c192ac7 Linus Torvalds 09 July 2023, 17:29:53 UTC MAINTAINERS 2: Electric Boogaloo We just sorted the entries and fields last release, so just out of a perverse sense of curiosity, I decided to see if we can keep things ordered for even just one release. The answer is "No. No we cannot". I suggest that all kernel developers will need weekly training sessions, involving a lot of Big Bird and Sesame Street. And at the yearly maintainer summit, we will all sing the alphabet song together. I doubt I will keep doing this. At some point "perverse sense of curiosity" turns into just a cold dark place filled with sadness and despair.

fb49c45 Suren Baghdasaryan 08 July 2023, 19:12:12 UTC fork: lock VMAs of the parent process when forking When forking a child process, the parent write-protects anonymous pages and COW-shares them with the child being forked using copy_present_pte(). We must not take any concurrent page faults on the source vma's as they are being processed, as we expect both the vma and the pte's behind it to be stable. For example, the anon_vma_fork() expects the parents vma->anon_vma to not change during the vma copy. A concurrent page fault on a page newly marked read-only by the page copy might trigger wp_page_copy() and a anon_vma_prepare(vma) on the source vma, defeating the anon_vma_clone() that wasn't done because the parent vma originally didn't have an anon_vma, but we now might end up copying a pte entry for a page that has one. Before the per-vma lock based changes, the mmap_lock guaranteed exclusion with concurrent page faults. But now we need to do a vma_start_write() to make sure no concurrent faults happen on this vma while it is being processed. This fix can potentially regress some fork-heavy workloads. Kernel build time did not show noticeable regression on a 56-core machine while a stress test mapping 10000 VMAs and forking 5000 times in a tight loop shows ~5% regression. If such fork time regression is unacceptable, disabling CONFIG_PER_VMA_LOCK should restore its performance. Further optimizations are possible if this regression proves to be problematic.

33313a7 Suren Baghdasaryan 08 July 2023, 19:12:11 UTC mm: lock newly mapped VMA which can be modified after it becomes visible mmap_region adds a newly created VMA into VMA tree and might modify it afterwards before dropping the mmap_lock. This poses a problem for page faults handled under per-VMA locks because they don't take the mmap_lock and can stumble on this VMA while it's still being modified. Currently this does not pose a problem since post-addition modifications are done only for file-backed VMAs, which are not handled under per-VMA lock. However, once support for handling file-backed page faults with per-VMA locks is added, this will become a race. Fix this by write-locking the VMA before inserting it into the VMA tree. Other places where a new VMA is added into VMA tree do not modify it after the insertion, so do not need the same locking.

fdb54d9 Andrey Konovalov 05 July 2023, 12:44:02 UTC kasan, slub: fix HW_TAGS zeroing with slub_debug Commit 946fa0dbf2d8 ("mm/slub: extend redzone check to extra allocated kmalloc space than requested") added precise kmalloc redzone poisoning to the slub_debug functionality. However, this commit didn't account for HW_TAGS KASAN fully initializing the object via its built-in memory initialization feature. Even though HW_TAGS KASAN memory initialization contains special memory initialization handling for when slub_debug is enabled, it does not account for in-object slub_debug redzones. As a result, HW_TAGS KASAN can overwrite these redzones and cause false-positive slub_debug reports. To fix the issue, avoid HW_TAGS KASAN memory initialization when slub_debug is enabled altogether. Implement this by moving the __slub_debug_enabled check to slab_post_alloc_hook. Common slab code seems like a more appropriate place for a slub_debug check anyway.

While updating mailmap for the going-away address, I also found that on current systems the manpage linked from the header comment changed. And in fact it looks like the git mailmap feature got its own manpage. This patch (of 2): On recent systems the git-shortlog manpage only tells people to See gitmailmap(5) So instead of sending people on a scavenger hunt, put that info into the header directly.

We got here due to a couple of bugs, each of which by itself was not quite enough to cause a problem: First of all, before commit c33c794828f2("mm: ptep_get() conversion"), the BUG() statement in huge_pte_alloc() was itself fragile: it relied upon compiler behavior to only read the pte once, despite using it twice in the same conditional. Next, commit c33c794828f2 ("mm: ptep_get() conversion") broke that delicate situation, by causing all direct pte reads to be done via READ_ONCE(). And so READ_ONCE() got called twice within the same BUG() conditional, leading to comparing (potentially, occasionally) different versions of the pte, and thus to false BUG() reports. Fix this by taking a single snapshot of the pte before using it in the BUG conditional. Now, that commit is only partially to blame here but, people doing bisections will invariably land there, so this will help them find a fix for a real crash. And also, the previous behavior was unlikely to ever expose this bug--it was fragile, yet not actually broken. So that's why I chose this commit for the Fixes tag, rather than the commit that created the original BUG() statement.

2b4f3b4 Suren Baghdasaryan 06 July 2023, 01:13:59 UTC fork: lock VMAs of the parent process when forking Patch series "Avoid memory corruption caused by per-VMA locks", v4. A memory corruption was reported in [1] with bisection pointing to the patch [2] enabling per-VMA locks for x86. Based on the reproducer provided in [1] we suspect this is caused by the lack of VMA locking while forking a child process. Patch 1/2 in the series implements proper VMA locking during fork. I tested the fix locally using the reproducer and was unable to reproduce the memory corruption problem. This fix can potentially regress some fork-heavy workloads. Kernel build time did not show noticeable regression on a 56-core machine while a stress test mapping 10000 VMAs and forking 5000 times in a tight loop shows ~7% regression. If such fork time regression is unacceptable, disabling CONFIG_PER_VMA_LOCK should restore its performance. Further optimizations are possible if this regression proves to be problematic. Patch 2/2 disables per-VMA locks until the fix is tested and verified. This patch (of 2): When forking a child process, parent write-protects an anonymous page and COW-shares it with the child being forked using copy_present_pte(). Parent's TLB is flushed right before we drop the parent's mmap_lock in dup_mmap(). If we get a write-fault before that TLB flush in the parent, and we end up replacing that anonymous page in the parent process in do_wp_page() (because, COW-shared with the child), this might lead to some stale writable TLB entries targeting the wrong (old) page. Similar issue happened in the past with userfaultfd (see flush_tlb_page() call inside do_wp_page()). Lock VMAs of the parent process when forking a child, which prevents concurrent page faults during fork operation and avoids this issue. This fix can potentially regress some fork-heavy workloads. Kernel build time did not show noticeable regression on a 56-core machine while a stress test mapping 10000 VMAs and forking 5000 times in a tight loop shows ~7% regression. If such fork time regression is unacceptable, disabling CONFIG_PER_VMA_LOCK should restore its performance. Further optimizations are possible if this regression proves to be problematic.

Since f26e58bf6f54 ("PCI/AER: Enable error reporting when AER is native"), the PCI core does this for all devices during enumeration, so the driver doesn't need to do it itself. Remove the redundant pci_enable_pcie_error_reporting() call from the driver. Also remove the corresponding pci_disable_pcie_error_reporting() from the driver .remove() path. Note that this only controls ERR_* Messages from the device.

cb6e45c Robert Hancock 06 June 2023, 18:25:58 UTC i2c: xiic: Don't try to handle more interrupt events after error In xiic_process, it is possible that error events such as arbitration lost or TX error can be raised in conjunction with other interrupt flags such as TX FIFO empty or bus not busy. Error events result in the controller being reset and the error returned to the calling request, but the function could potentially try to keep handling the other events, such as by writing more messages into the TX FIFO. Since the transaction has already failed, this is not helpful and will just cause issues. This problem has been present ever since: commit 7f9906bd7f72 ("i2c: xiic: Service all interrupts in isr") which allowed non-error events to be handled after errors, but became more obvious after: commit 743e227a8959 ("i2c: xiic: Defer xiic_wakeup() and __xiic_start_xfer() in xiic_process()") which reworked the code to add a WARN_ON which triggers if both the xfer_more and wakeup_req flags were set, since this combination is not supposed to happen, but was occurring in this scenario. Skip further interrupt handling after error flags are detected to avoid this problem.

89dbb33 Takashi Iwai 06 July 2023, 15:53:57 UTC ALSA: jack: Fix mutex call in snd_jack_report() snd_jack_report() is supposed to be callable from an IRQ context, too, and it's indeed used in that way from virtsnd driver. The fix for input_dev race in commit 1b6a6fc5280e ("ALSA: jack: Access input_dev under mutex"), however, introduced a mutex lock in snd_jack_report(), and this resulted in a potential sleep-in-atomic. For addressing that problem, this patch changes the relevant code to use the object get/put and removes the mutex usage. That is, snd_jack_report(), it takes input_get_device() and leaves with input_put_device() for assuring the input_dev being assigned. Although the whole mutex could be reduced, we keep it because it can be still a protection for potential races between creation and deletion.
