This will write b_data, which was never triggered on and thus\ncontains a wrong (old) checksum.\n\nThis patch fixes the problem by calling the trigger at the moment data is\nfrozen for journal commit - i.e., either when b_frozen_data is created by\ndo_get_write_access or just before we write a buffer to the log if\nb_frozen_data does not exist. We also rename the trigger to t_frozen as\nthat better describes when it is called.\n\nSigned-off-by: Jan Kara \u003cjack@suse.cz\u003e\nSigned-off-by: Mark Fasheh \u003cmfasheh@suse.com\u003e\nSigned-off-by: Joel Becker \u003cjoel.becker@oracle.com\u003e\n" }, { "commit": "5a0790c2c4a18435759a70e1562450035d778339", "tree": "80acb12d0e37196cf60ae4ca150c6b556115f302", "parents": [ "07a038245b28df9196ffb2e8cc626e9b956a4e23" ], "author": { "name": "Andi Kleen", "email": "andi@firstfloor.org", "time": "Mon Jun 14 13:28:03 2010 -0400" }, "committer": { "name": "Theodore Ts\u0027o", "email": "tytso@mit.edu", "time": "Mon Jun 14 13:28:03 2010 -0400" }, "message": "ext4: remove initialized but not read variables\n\nNo real bugs found, just removed some dead code.\n\nFound by gcc 4.6\u0027s new warnings.\n\nSigned-off-by: Andi Kleen \u003cak@linux.intel.com\u003e\nSigned-off-by: \"Theodore Ts\u0027o\" \u003ctytso@mit.edu\u003e\n" }, { "commit": "8ac97b74bca1fc8a63b28cc6121519d1cfa2af99", "tree": "04f00eada6c77edd95b6a56446e4a330266274e5", "parents": [ "c2d45b4da042720ae94648b417d0e051742441d4" ], "author": { "name": "Bill Pemberton", "email": "wfp5p@virginia.edu", "time": "Fri Apr 30 09:34:31 2010 -0400" }, "committer": { "name": "Jiri Kosina", "email": "jkosina@suse.cz", "time": "Tue May 11 10:04:36 2010 +0200" }, "message": "jbd2: use NULL instead of 0 when pointer is needed\n\nFixes sparse warning:\n\nfs/jbd2/journal.c:1892:9: warning: Using plain integer as NULL pointer\n\nSigned-off-by: Bill Pemberton \u003cwfp5p@virginia.edu\u003e\nCC: linux-ext4@vger.kernel.org\nSigned-off-by: Jiri Kosina \u003cjkosina@suse.cz\u003e\n" }, { "commit": "d2eecb03936878ec574ade5532fa83df7d75dde7", "tree": "f7ef8bd29096ba6c073308cd3b674857be1545d4", "parents": [ "f8ec9d6837241865cf99bed97bb99f4399fd5a03" ], "author": { "name": "Theodore Ts\u0027o", "email": "tytso@mit.edu", "time": "Mon Dec 07 10:36:20 2009 -0500" }, "committer": { "name": "Theodore Ts\u0027o", "email": "tytso@mit.edu", "time": "Mon Dec 07 10:36:20 2009 -0500" }, "message": "ext4: Use slab allocator for sub-page sized allocations\n\nNow that the SLUB seems to be fixed so that it respects the requested\nalignment, use kmem_cache_alloc() to allocator if the block size of\nthe buffer heads to be allocated is less than the page size.\nPreviously, we were using 16k page on a Power system for each buffer,\neven when the file system was using 1k or 4k block size.\n\nSigned-off-by: \"Theodore Ts\u0027o\" \u003ctytso@mit.edu\u003e\n\n\n" }, { "commit": "3ebfdf885acedafcadceb4007e77438479094135", "tree": "1bd9a4b223aa22e201af9a87868a33ec53605daf", "parents": [ "c8afb44682fcef6273e8b8eb19fab13ddd05b386" ], "author": { "name": "Andrew Morton", "email": "akpm@linux-foundation.org", "time": "Wed Dec 23 08:05:15 2009 -0500" }, "committer": { "name": "Theodore Ts\u0027o", "email": "tytso@mit.edu", "time": "Wed Dec 23 08:05:15 2009 -0500" }, "message": "jbd2: don\u0027t use __GFP_NOFAIL in journal_init_common()\n\nIt triggers the warning in get_page_from_freelist(), and it isn\u0027t\nappropriate to use __GFP_NOFAIL here anyway.\n\nAddresses http://bugzilla.kernel.org/show_bug.cgi?id\u003d14843\n\nReported-by: Christian Casteyde \u003ccasteyde.christian@free.fr\u003e\nSigned-off-by: Andrew Morton \u003cakpm@linux-foundation.org\u003e\nSigned-off-by: \"Theodore Ts\u0027o\" \u003ctytso@mit.edu\u003e\n" }, { "commit": "765f8361902d015c864d5e62019b2f139452d7ef", "tree": "f872385ae91fc926b036038e583a7f72ab5f3459", "parents": [ "39bc680a8160bb9d6743f7873b535d553ff61058" ], "author": { "name": "Yin Kangkai", "email": "kangkai.yin@intel.com", "time": "Tue Dec 15 14:48:25 2009 -0800" }, "committer": { "name": "Jan Kara", "email": "jack@suse.cz", "time": "Wed Dec 23 13:44:13 2009 +0100" }, "message": "jbd: jbd-debug and jbd2-debug should be writable\n\njbd-debug and jbd2-debug is currently read-only (S_IRUGO), which is not\ncorrect.

Then, before they can be dirtied again,\n kjournald exits, seeing the UMOUNT flag and the dirty pages are\n never written to the backing block device, causing long symlink\n corruption and exposing new or previously freed block data to\n userspace.\n\nThis can be reproduced with a script created by Eric Sandeen\n\u003csandeen@redhat.com\u003e:\n\n #!/bin/bash\n\n umount /mnt/test2\n mount /dev/sdb4 /mnt/test2\n rm -f /mnt/test2/*\n dd if\u003d/dev/zero of\u003d/mnt/test2/bigfile bs\u003d1M count\u003d512\n touch /mnt/test2/thisisveryveryveryveryveryveryveryveryveryveryveryveryveryveryveryverylongfilename\n ln -s /mnt/test2/thisisveryveryveryveryveryveryveryveryveryveryveryveryveryveryveryverylongfilename\n /mnt/test2/link\n umount /mnt/test2\n mount /dev/sdb4 /mnt/test2\n ls /mnt/test2/\n\nThis patch fixes jbd2_journal_start_commit() to always return 1 when\nthere\u0027s a transaction committing or queued for commit.\n\nSigned-off-by: Jan Kara \u003cjack@suse.cz\u003e\nSigned-off-by: \"Theodore Ts\u0027o\" \u003ctytso@mit.edu\u003e\nCC: Eric Sandeen \u003csandeen@redhat.com\u003e\nCC: linux-ext4@vger.kernel.org\n" }, { "commit": "c225aa57ff4ffe715df4692676b77c815a337236", "tree": "af70801def246873525ca5003b1a91adf91e024b", "parents": [ "18e352e4a73465349711a9324767e1b2453383e2" ], "author": { "name": "Simon Holm Thøgersen", "email": "odie@cs.aau.dk", "time": "Sun Jan 11 22:34:01 2009 -0500" }, "committer": { "name": "Theodore Ts\u0027o", "email": "tytso@mit.edu", "time": "Sun Jan 11 22:34:01 2009 -0500" }, "message": "ext4: fix wrong use of do_div\n\nthe following warning:\n\nfs/jbd2/journal.c: In function ‘jbd2_seq_info_show’:\nfs/jbd2/journal.c:850: warning: format ‘%lu’ expects type ‘long\nunsigned int’, but argument 3 has type ‘uint32_t’\n\nis caused by wrong usage of do_div that modifies the dividend in-place\nand returns the quotient.

Just before writing a metadata\nbuffer to the journal, jbd2 will optionally call a commit trigger associated\nwith the buffer. If the journal is aborted, an abort trigger will be\ncalled on any dirty buffers as they are dropped from pending\ntransactions.\n\nocfs2 will use this feature.\n\nInitially I tried to come up with a more generic trigger that could be\nused for non-buffer-related events like transaction completion. It\ndoesn\u0027t tie nicely, because the information a buffer trigger needs\n(specific to a journal_head) isn\u0027t the same as what a transaction\ntrigger needs (specific to a tranaction_t or perhaps journal_t). So I\nimplemented a buffer set, with the understanding that\njournal/transaction wide triggers should be implemented separately.\n\nThere is only one trigger set allowed per buffer. I can\u0027t think of any\nreason to attach more than one set. Contrast this with a journal or\ntransaction in which multiple places may want to watch the entire\ntransaction separately.\n\nThe trigger sets are considered static allocation from the jbd2\nperspective. ocfs2 will just have one trigger set per block type,\nsetting the same set on every bh of the same type.\n\nSigned-off-by: Joel Becker \u003cjoel.becker@oracle.com\u003e\nCc: \"Theodore Ts\u0027o\" \u003ctytso@mit.edu\u003e\nCc: \u003clinux-ext4@vger.kernel.org\u003e\nSigned-off-by: Mark Fasheh \u003cmfasheh@suse.com\u003e\n" }, { "commit": "4a9bf99b205448ec1f0cbdee1776a29f9c503ce4", "tree": "a1bd3a27526debaf972460c4ea0df0fd423c4026", "parents": [ "ba80b1019aa722b24506db1ee755e0bb2f513022" ], "author": { "name": "Theodore Ts\u0027o", "email": "tytso@mit.edu", "time": "Sat Jan 03 22:56:44 2009 -0500" }, "committer": { "name": "Theodore Ts\u0027o", "email": "tytso@mit.edu", "time": "Sat Jan 03 22:56:44 2009 -0500" }, "message": "jbd2: Add pid and journal device name to the \"kjournald2 starting\" message\n\nSigned-off-by: \"Theodore Ts\u0027o\" \u003ctytso@mit.edu\u003e\n" }, { "commit": "c31910672376dfb8d020e32afa7249763bcd924a", "tree": "3f2b95a1d4a4da76d85d5bf32534fa3d15a82eac", "parents": [ "c39a7f84d7845aa95d1c7c168f38215aedcc13c2" ], "author": { "name": "Theodore Ts\u0027o", "email": "tytso@mit.edu", "time": "Tue Jan 06 11:14:25 2009 -0500" }, "committer": { "name": "Theodore Ts\u0027o", "email": "tytso@mit.edu", "time": "Tue Jan 06 11:14:25 2009 -0500" }, "message": "ext4: Remove code to create the journal inode\n\nThis code has been obsolete in quite some time, since the supported\nmethod for adding a journal inode is to use tune2fs (or to creating\nnew filesystem with a journal via mke2fs or mkfs.ext4).\n\nSigned-off-by: \"Theodore Ts\u0027o\" \u003ctytso@mit.edu\u003e\n" }, { "commit": "1a0d3786dd57dbd74f340322054c3d618b999dcf", "tree": "b10b3ed6cb60ee34a4e8140e60da2ecc34b52f32", "parents": [ "498e5f24158da7bf8fa48074a70e370e22844492" ], "author": { "name": "Theodore Ts\u0027o", "email": "tytso@mit.edu", "time": "Wed Nov 05 00:09:22 2008 -0500" }, "committer": { "name": "Theodore Ts\u0027o", "email": "tytso@mit.edu", "time": "Wed Nov 05 00:09:22 2008 -0500" }, "message": "jbd2: Remove a large array of bh\u0027s from the stack of the checkpoint routine\n\njbd2_log_do_checkpoint()n is one of the kernel\u0027s largest stack users.\nMove the array of buffer head\u0027s from the stack of jbd2_log_do_checkpoint()\nto the in-core journal structure.\n\nSigned-off-by: \"Theodore Ts\u0027o\" \u003ctytso@mit.edu\u003e\n" }, { "commit": "30773840c19cea60dcef39545960d541b1ac1cf8", "tree": "f220a2dce451a40dc7264e8fd70c77c5a3908873", "parents": [ "d7cfa4684d82f58e5d7cb73b8a3c88c169937f25" ], "author": { "name": "Theodore Ts\u0027o", "email": "tytso@mit.edu", "time": "Sat Jan 03 20:27:38 2009 -0500" }, "committer": { "name": "Theodore Ts\u0027o", "email": "tytso@mit.edu", "time": "Sat Jan 03 20:27:38 2009 -0500" }, "message": "ext4: add fsync batch tuning knobs\n\nAdd new mount options, min_batch_time and max_batch_time, which\ncontrols how long the jbd2 layer should wait for additional filesystem\noperations to get batched with a synchronous write transaction.\n\nSigned-off-by: \"Theodore Ts\u0027o\" \u003ctytso@mit.edu\u003e\n" }, { "commit": "d7cfa4684d82f58e5d7cb73b8a3c88c169937f25", "tree": "1a47a0b3f6a9964c965e590fb3c438c8916bc357", "parents": [ "e07f7183a486cf9783d1f8c9d2997b5b39eeb2d4" ], "author": { "name": "Theodore Ts\u0027o", "email": "tytso@mit.edu", "time": "Wed Dec 17 00:20:45 2008 -0500" }, "committer": { "name": "Theodore Ts\u0027o", "email": "tytso@mit.edu", "time": "Wed Dec 17 00:20:45 2008 -0500" }, "message": "ext4: display average commit time\n\nDisplay the average commit time (which is used by the ext4 fsync\nbatching patch) in /proc/fs/jbd2/*/info for performance tuning\npurposes.\n\nSigned-off-by: \"Theodore Ts\u0027o\" \u003ctytso@mit.edu\u003e\n" }, { "commit": "2423840ded13e6d3b52d88aff8d033bb78fafd08", "tree": "9c82375eb1f17a635de090aa0f944b67c41fc981", "parents": [ "8c3f25d8950c3e9fe6c9849f88679b3f2a071550" ], "author": { "name": "Sami Liedes", "email": "sliedes@cc.hut.fi", "time": "Sun Nov 02 19:23:30 2008 -0500" }, "committer": { "name": "Theodore Ts\u0027o", "email": "tytso@mit.edu", "time": "Sun Nov 02 19:23:30 2008 -0500" }, "message": "jbd2: deregister proc on failure in jbd2_journal_init_inode\n\njbd2_journal_init_inode() does not call jbd2_stats_proc_exit() on all\nfailure paths after calling jbd2_stats_proc_init().
