snapshots and inode_cache flush\n\nThe btrfs snapshotting code requires that once a root has been\nsnapshotted, we don\u0027t change it during a commit.\n\nBut there are two cases to lead to tree corruptions:\n\n1) multi-thread snapshots can commit serveral snapshots in a transaction,\n and this may change the src root when processing the following pending\n snapshots, which lead to the former snapshots corruptions;\n\n2) the free inode cache was changing the roots when it root the cache,\n which lead to corruptions.\n\nThis fixes things by making sure we force COW the block after we create a\nsnapshot during commiting a transaction, then any changes to the roots\nwill result in COW, and we get all the fs roots and snapshot roots to be\nconsistent.\n\nSigned-off-by: Liu Bo

This is because\nwe try to steal from the delalloc block rsv to satisfy a reservation to update\nthe inode. The problem with this is we don\u0027t explicitly save space for updating\nthe inode when doing delalloc. This is kind of a problem and we\u0027ve gotten away\nwith this because way back when we just stole from the delalloc reserve without\nany questions, and this worked out fine because generally speaking the leaf had\nbeen modified either by the mtime update when we did the original write or\nbecause we just updated the leaf when we inserted the file extent item, only on\nrare occasions had the leaf not actually been modified, and that was still ok\nbecause we\u0027d just use a block or two out of the over-reservation that is\ndelalloc.\n\nThen came the delayed inode stuff. This is amazing, except it wants a full\nreservation for updating the inode since it may do it at some point down the\nroad after we\u0027ve written the blocks and we have to recow everything again. This\nworked out because the delayed inode stuff just stole from the global reserve,\nthat is until recently when I changed that because it caused other problems.\n\nSo here we are, we\u0027re doing everything right and being screwed for it. So take\nan extra reservation for the inode at delalloc reservation time and carry it\nthrough the life of the delalloc reservation. If we need it we can steal it in\nthe delayed inode stuff. If we have already stolen it try and do a normal\nmetadata reservation. If that fails try to steal from the delalloc reservation.\nIf _that_ fails we\u0027ll get a WARN_ON() so I can start thinking of a better way to\nsolve this and in the meantime we\u0027ll steal from the global reserve.\n\nWith this patch I ran xfstests 13 in a loop for a couple of hours and didn\u0027t see\nany problems.\n\nSigned-off-by: Josef Bacik \u003cjosef@redhat.com\u003e\nSigned-off-by: Chris Mason \u003cchris.mason@oracle.com\u003e\n" }, { "commit": "917c16b2b69fc2eeb432eabca73258f08c58361e", "tree": "3eb8b7d59bbb8c7d6cb54876428b485e72878692", "parents": [ "45ea6095c8f0d6caad5658306416a5d254f1205e" ], "author": { "name": "Chris Mason", "email": "chris.mason@oracle.com", "time": "Tue Nov 08 14:49:59 2011 -0500" }, "committer": { "name": "Chris Mason", "email": "chris.mason@oracle.com", "time": "Tue Nov 08 14:49:59 2011 -0500" }, "message": "Btrfs: fix oops on NULL trans handle in btrfs_truncate\n\nIf we fail to reserve space in the transaction during truncate, we can\nerror out with a NULL trans handle.

It\u0027s\nnot the delayed insertion stuffs fault, it\u0027s all just stupid. When marking an\ninode dirty for oh say updating the time on it, we just do a\nbtrfs_join_transaction, which doesn\u0027t reserve any space. This is stupid because\nwe\u0027re going to have to have space reserve to make this change, but we do it\nbecause it\u0027s fast because chances are we\u0027re going to call it over and over again\nand it doesn\u0027t matter. Well thanks to the delayed insertion stuff this is\nmostly the case, so we do actually need to make this reservation. So if\ntrans-\u003ebytes_reserved is 0 then try to do a normal reservation. If not return\nENOSPC which will make the btrfs_dirty_inode start a proper transaction which\nwill let it do the whole ENOSPC dance and reserve enough space for the delayed\ninsertion to steal the reservation from the transaction.\n\nThe other stupid thing we do is not reserve space for the inode when writing to\nthe thing. Usually this is ok since we have to update the time so we\u0027d have\nalready done all this work before we get to the endio stuff, so it doesn\u0027t\nmatter. But this is stupid because we could write the data after the\ntransaction commits where we changed the mtime of the inode so we have to cow\nall the way down to the inode anyway. This used to be masked by the delalloc\nreservation stuff, but because we delay the update it doesn\u0027t get masked in this\ncase. So again the delayed insertion stuff bites us in the ass. So if our\ntrans-\u003eblock_rsv is delalloc, just steal the reservation from the delalloc\nreserve. Hopefully this won\u0027t bite us in the ass, but I\u0027ve said that before.\n\nWith this patch stress.sh no longer spits out those stupid warnings (famous last\nwords).

I was migrating the bytes from the transaction reserve to the\nglobal reserve and then releasing from the global reserve in\nbtrfs_end_transaction(). The problem with this is that a migrate will jack up\nthe size for the destination, but leave the size alone for the source, with the\nidea that you can do a release normally on the source and it all washes out, and\nthen you can do a release again on the destination and it works out right. My\nway was skipping the release on the trans_block_rsv which still had the jacked\nup size from our original reservation. So instead release manually from the\nglobal reserve if this transaction was using it, and then set the\ntrans-\u003eblock_rsv back to the trans_block_rsv so that btrfs_end_transaction\ncleans everything up properly. With this patch xfstest 83 doesn\u0027t emit warnings\nabout leaking space.

Sometimes we were allowing tree log blocks to be reused after\nthe tree log was committed but before the transaction commit was done.\n\nThis allowed a future metadata write to overwrite the tree log data. It\nis fixed by adding a new variant of freeing reserved extents that always\npins them. Credit goes to Stefan Behrens and Arne Jansen for many many\nhours spent tracking this bug down.\n\nDuring tree log replay, we do a pass through the tree log and pin all\nthe extents we find. This makes sure the replay code won\u0027t go in and\nuse any of those blocks for new allocations during replay. The problem\nis the free space cache isn\u0027t honoring these pinned extents. So the\nallocator can end up handing them out, leading to all kinds of problems\nduring replay.\n\nThe fix here is to force any free space cache to load while we pin the\nextents, and then to make sure we remove the pinned extents from the\nfree space rbtree.\n\nSigned-off-by: Chris Mason \u003cchris.mason@oracle.com\u003e\nReported-by: Stefan Behrens \u003csbehrens@giantdisaster.de\u003e\n" }, { "commit": "1eae31e918972bbeefc119d23c1d67674f49a301", "tree": "b6c1df4d25699812a83f107187b407d53abeb82e", "parents": [ "cd354ad613a393424f85333ceed6b15e07fb94ae" ], "author": { "name": "Chris Mason", "email": "chris.mason@oracle.com", "time": "Fri Oct 14 06:31:20 2011 -0400" }, "committer": { "name": "Chris Mason", "email": "chris.mason@oracle.com", "time": "Sun Nov 06 03:03:47 2011 -0500" }, "message": "Btrfs: make sure btrfs_remove_free_space doesn\u0027t leak EAGAIN\n\nbtrfs_remove_free_space needs to make sure to set ret back to a\nvalid return value after setting it to EAGAIN, otherwise we return\nit to the callers.\n\nSigned-off-by: Chris Mason \u003cchris.mason@oracle.com\u003e\n" }, { "commit": "cd354ad613a393424f85333ceed6b15e07fb94ae", "tree": "98261d8cc0a0f3808fd34037629a92d31a670b19", "parents": [ "dff51cd1c60856c28f5d22a571294c2b70b6b322" ], "author": { "name": "Chris Mason", "email": "chris.mason@oracle.com", "time": "Thu Oct 20 15:45:37 2011 -0400" }, "committer": { "name": "Chris Mason", "email": "chris.mason@oracle.com", "time": "Sun Nov 06 03:03:47 2011 -0500" }, "message": "Btrfs: don\u0027t wait as long for more batches during SSD log commit\n\nWhen we\u0027re doing log commits, we try to wait for more writers to come in\nand make the commit bigger.
