Essentially these cases all imply that, tree-log.c:copy_items(), is not invoked for the leafs that delimit holes, because nothing changed those leafs in the current transaction. And it's precisely copy_items() where we currenly detect and log holes, which works as long as the holes are between file extent items in the input leaf or between the beginning of input leaf and the previous leaf or between the last item in the leaf and the next leaf. First example where we miss a hole: *) The extent items of the inode span multiple leafs; *) The punched hole covers a range that affects only the extent items of the first leaf; *) The fsync operation is done in full mode (BTRFS_INODE_NEEDS_FULL_SYNC is set in the inode's runtime flags). That results in the hole not existing after replaying the log tree. For example, if the fs/subvolume tree has the following layout for a particular inode: Leaf N, generation 10: [ ... INODE_ITEM INODE_REF EXTENT_ITEM (0 64K) EXTENT_ITEM (64K 128K) ] Leaf N + 1, generation 10: [ EXTENT_ITEM (128K 64K) ... ] If at transaction 11 we punch a hole coverting the range [0, 128K[, we end up dropping the two extent items from leaf N, but we don't touch the other leaf, so we end up in the following state: Leaf N, generation 11: [ ... INODE_ITEM INODE_REF ] Leaf N + 1, generation 10: [ EXTENT_ITEM (128K 64K) ... ] A full fsync after punching the hole will only process leaf N because it was modified in the current transaction, but not leaf N + 1, since it was not modified in the current transaction (generation 10 and not 11). As a result the fsync will not log any holes, because it didn't process any leaf with extent items. Second example where we will miss a hole: *) An inode as its items spanning 5 (or more) leafs; *) A hole is punched and it covers only the extents items of the 3rd leaf. This resulsts in deleting the entire leaf and not touching any of the other leafs. So the only leaf that is modified in the current transaction, when punching the hole, is the first leaf, which contains the inode item. During the full fsync, the only leaf that is passed to copy_items() is that first leaf, and that's not enough for the hole detection code in copy_items() to determine there's a hole between the last file extent item in the 2nd leaf and the first file extent item in the 3rd leaf (which was the 4th leaf before punching the hole). Fix this by scanning all leafs and punch holes as necessary when doing a full fsync (less common than a non-full fsync) when the NO_HOLES feature is enabled. The lack of explicit file extent items to mark holes makes it necessary to scan existing extents to determine if holes exist. A test case for fstests follows soon.

If someone wants it applied there, or to any other stable or longterm tree, then please email the backport, including the original git commit id to <stable(a)vger.kernel.org>. thanks, greg k-h ------------------ original commit in Linus's tree ------------------ >From 547c556f4db7c09447ecf5f833ab6aaae0c5ab58 Mon Sep 17 00:00:00 2001 From: Eric Biggers <ebiggers(a)google.com> Date: Tue, 31 Dec 2019 12:11:49 -0600 Subject: [PATCH] ext4: fix deadlock allocating crypto bounce page from mempool ext4_writepages() on an encrypted file has to encrypt the data, but it can't modify the pagecache pages in-place, so it encrypts the data into bounce pages and writes those instead. All bounce pages are allocated from a mempool using GFP_NOFS. This is not correct use of a mempool, and it can deadlock. This is because GFP_NOFS includes __GFP_DIRECT_RECLAIM, which enables the "never fail" mode for mempool_alloc() where a failed allocation will fall back to waiting for one of the preallocated elements in the pool. But since this mode is used for all a bio's pages and not just the first, it can deadlock waiting for pages already in the bio to be freed. This deadlock can be reproduced by patching mempool_alloc() to pretend that pool->alloc() always fails (so that it always falls back to the preallocations), and then creating an encrypted file of size > 128 KiB. Fix it by only using GFP_NOFS for the first page in the bio. For subsequent pages just use GFP_NOWAIT, and if any of those fail, just submit the bio and start a new one. This will need to be fixed in f2fs too, but that's less straightforward.

FAILED: patch "[PATCH] ext4: fix deadlock allocating crypto bounce page from mempool" failed to apply to 4.9-stable tree

The patch below does not apply to the 4.9-stable tree. If someone wants it applied there, or to any other stable or longterm tree, then please email the backport, including the original git commit id to <stable(a)vger.kernel.org>. thanks, greg k-h ------------------ original commit in Linus's tree ------------------ >From 547c556f4db7c09447ecf5f833ab6aaae0c5ab58 Mon Sep 17 00:00:00 2001 From: Eric Biggers <ebiggers(a)google.com> Date: Tue, 31 Dec 2019 12:11:49 -0600 Subject: [PATCH] ext4: fix deadlock allocating crypto bounce page from mempool ext4_writepages() on an encrypted file has to encrypt the data, but it can't modify the pagecache pages in-place, so it encrypts the data into bounce pages and writes those instead. All bounce pages are allocated from a mempool using GFP_NOFS. This is not correct use of a mempool, and it can deadlock. This is because GFP_NOFS includes __GFP_DIRECT_RECLAIM, which enables the "never fail" mode for mempool_alloc() where a failed allocation will fall back to waiting for one of the preallocated elements in the pool. But since this mode is used for all a bio's pages and not just the first, it can deadlock waiting for pages already in the bio to be freed. This deadlock can be reproduced by patching mempool_alloc() to pretend that pool->alloc() always fails (so that it always falls back to the preallocations), and then creating an encrypted file of size > 128 KiB. Fix it by only using GFP_NOFS for the first page in the bio. For subsequent pages just use GFP_NOWAIT, and if any of those fail, just submit the bio and start a new one. This will need to be fixed in f2fs too, but that's less straightforward.
