Many files:
pass*.c, super.c: Massive changes to avoid using printf and com_err
routines. All diagnostic messages are now routed through the
fix_problem interface.
pass2.c (check_dir_block): Check for duplicate '.' and '..' entries.
problem.c, problem.h: Add new problem codes PR_2_DUP_DOT and
PR_2_DUP_DOT_DOT.
problem.c: Added new problem codes for some of the superblock
corruption checks, and for the pass header messages. ("Pass
1: xxxxx")
util.c (print_resource_track): Now takes a description argument.
super.c, unix.c, e2fsck.c: New files to separate out the
operating-specific operations out from e2fsck.c. e2fsck.c now
contains the global e2fsck context management routines, and
super.c contains the "pass 0" initial validation of the
superblock and global block group descriptors.
pass1.c, pass2.c, pass3.c, pass4.c, pass5.c, util.c: Eliminate
(nearly) all global variables and moved them to the e2fsck
context structure.
problem.c, problem.h: Added new problem codes PR_0_SB_CORRUPT,
PR_0_FS_SIZE_WRONG, PR_0_NO_FRAGMENTS, PR_0_BLOCKS_PER_GROUP,
PR_0_FIRST_DATA_BLOCK
expect.1, expect.2:

that superblock to be used after a restart; otherwise changes to the
block group descriptors end up getting ignored.

the problem message if e2fsck is run with the -n option.
problem.c, problem.h (PR_2_SET_FILETYPE, PR_2_BAD_FILETYPE): Add new

ChangeLog, mke2fs.c, tune2fs.8.in:
tune2fs.8.in: Fix minor display bug in the nroff.
mke2fs.c (show_stats, write_inode_tables): Use the log10 function to
calculate the display of block numbers so that things look nice on an
80 character display.
mke2fs.c (usage): Add the sparse-super-flag to the usage message.
ChangeLog, e2fsck.c, pass1.c, pass2.c, problem.c, problem.h, unix.c:
unix.c (main): Move ext2fs_close() after e2fsck_free_context() since
e2fsck_free_context may reference data in ctx->fs.
e2fsck.c (e2fsck_reset_context): Make sure ctx->fs is non-NULL before
checking ctx->fs->dblist.
pass1.c (e2fsck_pass1): Use the device check subroutine on FIFO's and
Socket's, so that we catch bogus immutable inodes.
pass2.c (process_bad_inode): Process bad socket and fifo's.
problem.h, problem.c: Define new problem codes PR_2_BAD_FIFO and
PR_2_BAD_SOCKET.

e2fsck: don't clobber critical metadata during check_blocks
If we encounter an inode with IND/DIND/TIND blocks or internal extent
tree blocks that point into critical FS metadata such as the
superblock, the group descriptors, the bitmaps, or the inode table,
it's quite possible that the validation code for those blocks is not
going to like what it finds, and it'll ask to try to fix the block.
Unfortunately, this happens before duplicate block processing (pass
1b), which means that we can end up doing stupid things like writing
extent blocks into the inode table, which multiplies e2fsck'
destructive effect and can render a filesystem unfixable.
To solve this, create a bitmap of all the critical FS metadata. If
before pass1b runs (basically check_blocks) we find a metadata block
that points into these critical regions, continue processing that
block, but avoid making any modifications, because we could be
misinterpreting inodes as block maps. Pass 1b will find the
multiply-owned blocks and fix that situation, which means that we can
then restart e2fsck from the beginning and actually fix whatever
problems we find.

fix_problem interface.
pass2.c (check_dir_block): Check for duplicate '.' and '..' entries.
problem.c, problem.h: Add new problem codes PR_2_DUP_DOT and
PR_2_DUP_DOT_DOT.
problem.c: Added new problem codes for some of the superblock
corruption checks, and for the pass header messages. ("Pass
1: xxxxx")
util.c (print_resource_track): Now takes a description argument.
super.c, unix.c, e2fsck.c: New files to separate out the
operating-specific operations out from e2fsck.c. e2fsck.c now
contains the global e2fsck context management routines, and
super.c contains the "pass 0" initial validation of the
superblock and global block group descriptors.
pass1.c, pass2.c, pass3.c, pass4.c, pass5.c, util.c: Eliminate
(nearly) all global variables and moved them to the e2fsck
context structure.
problem.c, problem.h: Added new problem codes PR_0_SB_CORRUPT,
PR_0_FS_SIZE_WRONG, PR_0_NO_FRAGMENTS, PR_0_BLOCKS_PER_GROUP,
PR_0_FIRST_DATA_BLOCK
expect.1, expect.2:
Updated tests to align with e2fsck problem.c changes.
