2023-06-15ext4: drop the call to ext4_error() from ext4_get_group_info()Fabio M. De Francesco1-11/+9
A recent patch added a call to ext4_error() which is problematic since some callers of the ext4_get_group_info() function may be holding a spinlock, whereas ext4_error() must never be called in atomic context. This triggered a report from Syzbot: "BUG: sleeping function called from invalid context in ext4_update_super" (see the link below). Therefore, drop the call to ext4_error() from ext4_get_group_info(). In the meantime use eight characters tabs instead of nine characters ones.

2023-06-15Revert "ext4: remove unnecessary check in ext4_bg_num_gdb_nometa"Kemeng Shi1-1/+4
This reverts commit ad3f09be6cfe332be8ff46c78e6ec0f8839107aa. The reverted commit was intended to simpfy the code to get group descriptor block number in non-meta block group by assuming s_gdb_count is block number used for all non-meta block group descriptors. However s_gdb_count is block number used for all meta *and* non-meta group descriptors. So s_gdb_group will be > actual group descriptor block number used for all non-meta block group which should be "total non-meta block group" / "group descriptors per block", e.g. s_first_meta_bg.

2023-06-12zswap: do not shrink if cgroup may not zswapNhat Pham1-2/+9
Before storing a page, zswap first checks if the number of stored pages exceeds the limit specified by memory.zswap.max, for each cgroup in the hierarchy. If this limit is reached or exceeded, then zswap shrinking is triggered and short-circuits the store attempt. However, since the zswap's LRU is not memcg-aware, this can create the following pathological behavior: the cgroup whose zswap limit is 0 will evict pages from other cgroups continually, without lowering its own zswap usage. This means the shrinking will continue until the need for swap ceases or the pool becomes empty. As a result of this, we observe a disproportionate amount of zswap writeback and a perpetually small zswap pool in our experiments, even though the pool limit is never hit. More generally, a cgroup might unnecessarily evict pages from other cgroups before we drive the memcg back below its limit. This patch fixes the issue by rejecting zswap store attempt without shrinking the pool when obj_cgroup_may_zswap() returns false.

2023-06-12page cache: fix page_cache_next/prev_miss off by oneMike Kravetz1-10/+16
Ackerley Tng reported an issue with hugetlbfs fallocate here[1]. The issue showed up after the conversion of hugetlb page cache lookup code to use page_cache_next_miss. Code in hugetlb fallocate, userfaultfd and GUP is now using page_cache_next_miss to determine if a page is present the page cache. The following statement is used. present = page_cache_next_miss(mapping, index, 1) != index; There are two issues with page_cache_next_miss when used in this way. 1) If the passed value for index is equal to the 'wrap-around' value, the same index will always be returned. This wrap-around value is 0, so 0 will be returned even if page is present at index 0. 2) If there is no gap in the range passed, the last index in the range will be returned. When passed a range of 1 as above, the passed index value will be returned even if the page is present. The end result is the statement above will NEVER indicate a page is present in the cache, even if it is. As noted by Ackerley in [1], users can see this by hugetlb fallocate incorrectly returning EEXIST if pages are already present in the file. In addition, hugetlb pages will not be included in core dumps if they need to be brought in via GUP. userfaultfd UFFDIO_COPY also uses this code and will not notice pages already present in the cache. It may try to allocate a new page and potentially return ENOMEM as opposed to EEXIST. Both page_cache_next_miss and page_cache_prev_miss have similar issues. Fix by: - Check for index equal to 'wrap-around' value and do not exit early. - If no gap is found in range, return index outside range. - Update function description to say 'wrap-around' value could be returned if passed as index.

2023-06-12nilfs2: reject devices with insufficient block countRyusuke Konishi1-1/+42
The current sanity check for nilfs2 geometry information lacks checks for the number of segments stored in superblocks, so even for device images that have been destructively truncated or have an unusually high number of segments, the mount operation may succeed. This causes out-of-bounds block I/O on file system block reads or log writes to the segments, the latter in particular causing "a_ops->writepages" to repeatedly fail, resulting in sync_inodes_sb() to hang. Fix this issue by checking the number of segments stored in the superblock and avoiding mounting devices that can cause out-of-bounds accesses. To eliminate the possibility of overflow when calculating the number of blocks required for the device from the number of segments, this also adds a helper function to calculate the upper bound on the number of segments and inserts a check using it.

2023-06-12lib/test_vmalloc.c: avoid garbage in page arrayLorenzo Stoakes1-1/+1
It turns out that alloc_pages_bulk_array() does not treat the page_array parameter as an output parameter, but rather reads the array and skips any entries that have already been allocated. This is somewhat unexpected and breaks this test, as we allocate the pages array uninitialised on the assumption it will be overwritten. As a result, the test was referencing uninitialised data and causing the PFN to not be valid and thus a WARN_ON() followed by a null pointer deref and panic. In addition, this is an array of pointers not of struct page objects, so we need only allocate an array with elements of pointer size. We solve both problems by simply using kcalloc() and referencing sizeof(struct page *) rather than sizeof(struct page).

2023-06-12nilfs2: fix possible out-of-bounds segment allocation in resize ioctlRyusuke Konishi1-0/+9
Syzbot reports that in its stress test for resize ioctl, the log writing function nilfs_segctor_do_construct hits a WARN_ON in nilfs_segctor_truncate_segments(). It turned out that there is a problem with the current implementation of the resize ioctl, which changes the writable range on the device (the range of allocatable segments) at the end of the resize process. This order is necessary for file system expansion to avoid corrupting the superblock at trailing edge. However, in the case of a file system shrink, if log writes occur after truncating out-of-bounds trailing segments and before the resize is complete, segments may be allocated from the truncated space. The userspace resize tool was fine as it limits the range of allocatable segments before performing the resize, but it can run into this issue if the resize ioctl is called alone. Fix this issue by changing nilfs_sufile_resize() to update the range of allocatable segments immediately after successful truncation of segment space in case of file system shrink.

2023-06-12kexec: support purgatories with .text.hot sectionsRicardo Ribalda1-1/+13
Patch series "kexec: Fix kexec_file_load for llvm16 with PGO", v7. When upreving llvm I realised that kexec stopped working on my test platform. The reason seems to be that due to PGO there are multiple .text sections on the purgatory, and kexec does not supports that. This patch (of 4): Clang16 links the purgatory text in two sections when PGO is in use: [ 1] .text PROGBITS 0000000000000000 00000040 00000000000011a1 0000000000000000 AX 0 0 16 [ 2] .rela.text RELA 0000000000000000 00003498 0000000000000648 0000000000000018 I 24 1 8 ...

This causes that image->start is calculated twice, once for .text and another time for .text.hot. The second calculation leaves image->start in a random location. Because of this, the system crashes immediately after: kexec_core: Starting new kernel Link: https://lkml.kernel.org/r/20230321-kexec_clang16-v7-0-b05c520b7296@chromium.org Link: https://lkml.kernel.org/r/20230321-kexec_clang16-v7-1-b05c520b7296@chromium.org Fixes: 930457057abe ("kernel/kexec_file.c: split up __kexec_load_puragory") Signed-off-by: Ricardo Ribalda <ribalda@chromium.org> Reviewed-by: Ross Zwisler <zwisler@google.com> Reviewed-by: Steven Rostedt (Google) <rostedt@goodmis.org> Reviewed-by: Philipp Rudo <prudo@redhat.com> Cc: Albert Ou <aou@eecs.berkeley.edu> Cc: Baoquan He <bhe@redhat.com> Cc: Borislav Petkov (AMD) <bp@alien8.de> Cc: Christophe Leroy <christophe.leroy@csgroup.eu> Cc: Dave Hansen <dave.hansen@linux.intel.com> Cc: Dave Young <dyoung@redhat.com> Cc: Eric W.

2023-06-12mm/uffd: allow vma to merge as much as possiblePeter Xu1-2/+6
We used to not pass in the pgoff correctly when register/unregister uffd regions, it caused incorrect behavior on vma merging and can cause mergeable vmas being separate after ioctls return. For example, when we have: vma1(range 0-9, with uffd), vma2(range 10-19, no uffd) Then someone unregisters uffd on range (5-9), it should logically become: vma1(range 0-4, with uffd), vma2(range 5-19, no uffd) But with current code we'll have: vma1(range 0-4, with uffd), vma3(range 5-9, no uffd), vma2(range 10-19, no uffd) This patch allows such merge to happen correctly before ioctl returns. This behavior seems to have existed since the 1st day of uffd. Since pgoff for vma_merge() is only used to identify the possibility of vma merging, meanwhile here what we did was always passing in a pgoff smaller than what we should, so there should have no other side effect besides not merging it. Let's still tentatively copy stable for this, even though I don't see anything will go wrong besides vma being split (which is mostly not user visible).

2023-06-12mm/uffd: fix vma operation where start addr cuts part of vmaPeter Xu1-0/+5
Patch series "mm/uffd: Fix vma merge/split", v2. This series contains two patches that fix vma merge/split for userfaultfd on two separate issues. Patch 1 fixes a regression since 6.1+ due to something we overlooked when converting to maple tree apis. The plan is we use patch 1 to replace the commit "2f628010799e (mm: userfaultfd: avoid passing an invalid range to vma_merge())" in mm-hostfixes-unstable tree if possible, so as to bring uffd vma operations back aligned with the rest code again. Patch 2 fixes a long standing issue that vma can be left unmerged even if we can for either uffd register or unregister. Many thanks to Lorenzo on either noticing this issue from the assert movement patch, looking at this problem, and also provided a reproducer on the unmerged vma issue [1]. [1] https://gist.github.com/lorenzo-stoakes/a11a10f5f479e7a977fc456331266e0e This patch (of 2): It seems vma merging with uffd paths is broken with either register/unregister, where right now we can feed wrong parameters to vma_merge() and it's found by recent patch which moved asserts upwards in vma_merge() by Lorenzo Stoakes: https://lore.kernel.org/all/ZFunF7DmMdK05MoF@FVFF77S0Q05N.cambridge.arm.com/ It's possible that "start" is contained within vma but not clamped to its start. We need to convert this into either "cannot merge" case or "can merge" case 4 which permits subdivision of prev by assigning vma to prev. As we loop, each subsequent VMA will be clamped to the start. This patch will eliminate the report and make sure vma_merge() calls will become legal again. One thing to mention is that the "Fixes: 29417d292bd0" below is there only to help explain where the warning can start to trigger, the real commit to fix should be 69dbe6daf104. Commit 29417d292bd0 helps us to identify the issue, but unfortunately we may want to keep it in Fixes too just to ease kernel backporters for easier tracking.

2023-06-12radix-tree: move declarations to headerArnd Bergmann4-6/+15
The xarray.c file contains the only call to radix_tree_node_rcu_free(), and it comes with its own extern declaration for it. This means the function definition causes a missing-prototype warning: lib/radix-tree.c:288:6: error: no previous prototype for 'radix_tree_node_rcu_free' [-Werror=missing-prototypes] Instead, move the declaration for this function to a new header that can be included by both, and do the same for the radix_tree_node_cachep variable that has the same underlying problem but does not cause a warning with gcc.

2023-06-12nilfs2: fix incomplete buffer cleanup in nilfs_btnode_abort_change_key()Ryusuke Konishi1-2/+10
A syzbot fault injection test reported that nilfs_btnode_create_block, a helper function that allocates a new node block for b-trees, causes a kernel BUG for disk images where the file system block size is smaller than the page size. This was due to unexpected flags on the newly allocated buffer head, and it turned out to be because the buffer flags were not cleared by nilfs_btnode_abort_change_key() after an error occurred during a b-tree update operation and the buffer was later reused in that state. Fix this issue by using nilfs_btnode_delete() to abandon the unused preallocated buffer in nilfs_btnode_abort_change_key().

2023-06-12io_uring/io-wq: don't clear PF_IO_WORKER on exitJens Axboe1-3/+0
A recent commit gated the core dumping task exit logic on current->flags remaining consistent in terms of PF_{IO,USER}_WORKER at task exit time. This exposed a problem with the io-wq handling of that, which explicitly clears PF_IO_WORKER before calling do_exit(). The reasons for this manual clear of PF_IO_WORKER is historical, where io-wq used to potentially trigger a sleep on exit. As the io-wq thread is exiting, it should not participate any further accounting. But these days we don't need to rely on current->flags anymore, so we can safely remove the PF_IO_WORKER clearing.

2023-06-12smb/client: print "Unknown" instead of bogus link speed valueEnzo Matsumiya1-1/+46
The virtio driver for Linux guests will not set a link speed to its paravirtualized NICs. This will be seen as -1 in the ethernet layer, and when some servers (e.g. samba) fetches it, it's converted to an unsigned value (and multiplied by 1000 * 1000), so in client side we end up with: 1) Speed: 4294967295000000 bps in DebugData. This patch introduces a helper that returns a speed string (in Mbps or Gbps) if interface speed is valid (>= SPEED_10 and <= SPEED_800000), or "Unknown" otherwise. The reason to not change the value in iface->speed is because we don't know the real speed of the HW backing the server NIC, so let's keep considering these as the fastest NICs available. Also print "Capabilities: None" when the interface doesn't support any.

2023-06-09s390/dasd: Use correct lock while counting channel queue lengthJan Höppner1-2/+2
The lock around counting the channel queue length in the BIODASDINFO ioctl was incorrectly changed to the dasd_block->queue_lock with commit 583d6535cb9d ("dasd: remove dead code"). This can lead to endless list iterations and a subsequent crash. The queue_lock is supposed to be used only for queue lists belonging to dasd_block. For dasd_device related queue lists the ccwdev lock must be used. Fix the mentioned issues by correctly using the ccwdev lock instead of the queue lock.
