The root cause of this bug was the fact that if\nan uninitalized bitmap block gets read in by userspace (which\ne2fsprogs does try to avoid, but can happen when the blocksize is less\nthan the pagesize and an adjacent blocks is read into memory)\next4_read_block_bitmap() was erroneously depending on the buffer\nuptodate flag to decide whether it needed to initialize the bitmap\nblock in memory --- i.e., to set the standard set of blocks in use by\na block group (superblock, bitmaps, inode table, etc.). Essentially,\next4_read_block_bitmap() assumed it was the only routine that might\ntry to read a block containing a block bitmap, which is simply not\ntrue. \n\nTo fix this, ext4_read_block_bitmap() and ext4_read_inode_bitmap()\nmust always initialize uninitialized bitmap blocks. Once a block or\ninode is allocated out of that bitmap, it will be marked as\ninitialized in the block group descriptor, so in general this won\u0027t\nresult any extra unnecessary work.\n\nSigned-off-by: Frederic Bohe \u003cfrederic.bohe@bull.net\u003e\nSigned-off-by: \"Theodore Ts\u0027o\" \u003ctytso@mit.edu\u003e\n" }, { "commit": "c2ea3fde61f1df1dbf062345f23277dcd6f01dfe", "tree": "53ecbf57416326810540494e814c05753bf30874", "parents": [ "240799cdf22bd789ea6852653c3b879d35ad0a6c" ], "author": { "name": "Theodore Ts\u0027o", "email": "tytso@mit.edu", "time": "Fri Oct 10 09:40:52 2008 -0400" }, "committer": { "name": "Theodore Ts\u0027o", "email": "tytso@mit.edu", "time": "Fri Oct 10 09:40:52 2008 -0400" }, "message": "ext4: Remove old legacy block allocator\n\nSigned-off-by: \"Theodore Ts\u0027o\" \u003ctytso@mit.edu\u003e\n" }, { "commit": "af5bc92dded4d98dfeabc8b5b9812571345b263d", "tree": "5cfaf27e673a09d3ad1341c175559be0a3ea990d", "parents": [ "e5f8eab8851dff162e7ade46f084cb8575dc45f7" ], "author": { "name": "Theodore Ts\u0027o", "email": "tytso@mit.edu", "time": "Mon Sep 08 22:25:24 2008 -0400" }, "committer": { "name": "Theodore Ts\u0027o", "email": "tytso@mit.edu", "time": "Mon Sep 08 22:25:24 2008 -0400" }, "message": "ext4: Fix whitespace checkpatch warnings/errors\n\nSigned-off-by: \"Theodore Ts\u0027o\" \u003ctytso@mit.edu\u003e\n\n" }, { "commit": "4776004f54e4190e104caf620fd0fa5909412236", "tree": "ebd37cb847d58d434ad4ea3bd98c77256f05347e", "parents": [ "1f7c14c62ce63805f9574664a6c6de3633d4a354" ], "author": { "name": "Theodore Ts\u0027o", "email": "tytso@mit.edu", "time": "Mon Sep 08 23:00:52 2008 -0400" }, "committer": { "name": "Theodore Ts\u0027o", "email": "tytso@mit.edu", "time": "Mon Sep 08 23:00:52 2008 -0400" }, "message": "ext4: Add printk priority levels to clean up checkpatch warnings\n\nSigned-off-by: \"Theodore Ts\u0027o\" \u003ctytso@mit.edu\u003e\n\n" }, { "commit": "c001077f4003fa75793bb62979baa6241dd8eb19", "tree": "74d37ab68e3cfe514b8a46bd8324ba713bdc605f", "parents": [ "37609fd5ae62db75026d9f53096a1fbc35e040d9" ], "author": { "name": "Eric Sandeen", "email": "sandeen@redhat.com", "time": "Tue Aug 19 22:19:50 2008 -0400" }, "committer": { "name": "Theodore Ts\u0027o", "email": "tytso@mit.edu", "time": "Tue Aug 19 22:19:50 2008 -0400" }, "message": "ext4: Fix bug where we return ENOSPC even though we have plenty of inodes\n\nThe find_group_flex() function starts with best_flex as the\nparent_fbg_group, which happens to have 0 inodes free.

Since the impact on the block allocator is\nminimal, this patch should have little or no effect on other block\nallocation algorithms. By controlling the inode allocation, it can\nbasically control where the initial search for new block begins and\nthus indirectly manipulate the block allocator.\n\nThis allocator favors data and meta-data locality so the disk will\ngradually be filled from block group zero upward. This helps improve\nperformance by reducing seek time.

This is this the most time consuming part\nof the filesystem check. The unintialized block group feature can greatly\nreduce e2fsck time by eliminating checking of uninitialized inodes.\n\nWith this feature, there is a a high water mark of used inodes for each block\ngroup. Block and inode bitmaps can be uninitialized on disk via a flag in the\ngroup descriptor to avoid reading or scanning them at e2fsck time. A checksum\nof each group descriptor is used to ensure that corruption in the group\ndescriptor\u0027s bit flags does not cause incorrect operation.\n\nThe feature is enabled through a mkfs option\n\n\tmke2fs /dev/ -O uninit_groups\n\nA patch adding support for uninitialized block groups to e2fsprogs tools has\nbeen posted to the linux-ext4 mailing list.\n\nThe patches have been stress tested with fsstress and fsx. In performance\ntests testing e2fsck time, we have seen that e2fsck time on ext3 grows\nlinearly with the total number of inodes in the filesytem. In ext4 with the\nuninitialized block groups feature, the e2fsck time is constant, based\nsolely on the number of used inodes rather than the total inode count.\nSince typical ext4 filesystems only use 1-10% of their inodes, this feature can\ngreatly reduce e2fsck time for users. With performance improvement of 2-20\ntimes, depending on how full the filesystem is.\n\nThe attached graph shows the major improvements in e2fsck times in filesystems\nwith a large total inode count, but few inodes in use.\n\nIn each group descriptor if we have\n\nEXT4_BG_INODE_UNINIT set in bg_flags:\n Inode table is not initialized/used in this group. So we can skip\n the consistency check during fsck.\nEXT4_BG_BLOCK_UNINIT set in bg_flags:\n No block in the group is used. So we can skip the block bitmap\n verification for this group.\n\nWe also add two new fields to group descriptor as a part of\nuninitialized group patch.\n\n __le16 bg_itable_unused; /* Unused inodes count */\n __le16 bg_checksum; /* crc16(sb_uuid+group+desc) */\n\nbg_itable_unused:\n\nIf we have EXT4_BG_INODE_UNINIT not set in bg_flags\nthen bg_itable_unused will give the offset within\nthe inode table till the inodes are used. This can be\nused by fsck to skip list of inodes that are marked unused.\n\nbg_checksum:\nNow that we depend on bg_flags and bg_itable_unused to determine\nthe block and inode usage, we need to make sure group descriptor\nis not corrupt. We add checksum to group descriptor to\ndetect corruption.
