blob: 9d1816bc81722769359d78da1dfa42eb518f0e59 [file] [log] [blame]
2003-04-21 Theodore Ts'o <tytso@mit.edu>
* Release of E2fsprogs 1.33
2003-04-19 Theodore Ts'o <tytso@mit.edu>
* rehash.c: Fix lint warnings by including string.h and ctype.h
* pass2.c (dict_de_cmp): Fix lint warnings by using const pointers.
* unix.c (e2fsck_simple_progress), e2fsck.h: Fix lint warnings by
using const pointers. Remove unused variables.
2003-04-17 Theodore Ts'o <tytso@mit.edu>
* rehash.c (name_cmp): Sort the deleted inodes to the end of the
list, for portability to systems that whose qsort does not
perform a stable sort.
2003-04-16 Theodore Ts'o <tytso@mit.edu>
* unix.c: Bracket progress bar output with control-A and control-B
characters. These characters are used as in-band
signalling to allow a logging program to filter out the
progress bar.
(PRS): Use setvbuf instead of setbuf to force stdout and
stderr to be non-buffered when the stdout/stderr are a pipe.
This fixes a cosmetic problem when using e2fsck under
logsave.
2003-04-12 Theodore Ts'o <tytso@mit.edu>
* unix.c: Add #ifdef around #include <sys/ioctl.h>
2003-04-05 Theodore Ts'o <tytso@mit.edu>
* super.c (check_super_block): Update the global free block and
inode counters from the block group specific counters
quietly. This is needed for an experimental patch which
eliminates locking the entire filesystem when allocating
blocks or inodes; if the filesystem is not unmounted
cleanly, the global counts may not be accurate.
2003-03-17 Theodore Ts'o <tytso@mit.edu>
* util.c: Explicitly declare e2fsck_global_ctx as extern for the
benefit of the Apple Darwin port.
2003-03-15 Theodore Ts'o <tytso@mit.edu>
* rehash.c (e2fsck_rehash_dir): If user specified the -n option,
skip trying to write out directory.
(e2fsck_rehash_directories): Fix the percentage
calculation in the progress bar.
2003-03-14 Theodore Ts'o <tytso@mit.edu>
* problem.c, problem.h (PR_2_REPORT_DUP_DIRENT): Add new problem
code.
* pass2.c (check_dir_block): Check for duplicate filenames within
a single directory block (because this is the easy case;
we don't currently check for duplicates that span
directory blocks, for now. Eventually for htree
directories we can do this by searching for all directory
blocks that have a hash overflow, and then searching the
adjacent blocks to find all other potential duplicates.)
* iscan.c, scantest.c, unix.c: And #ifdef protection around
#include of malloc.h
* rehash.c (duplicate_search_and_fix): Now search for duplicates
filenames, and either prompt to remove a complete
duplicate entry, or to rename a duplicate filename.
(e2fsck_rehash_dir): Use a progress bar to report
progress, and don't print all of the directory inodes as
they are optimized.
* problem.c, problem.h (PR_2_DUPLICATE_DIRENT,
PR_2_NON_UNIQUE_FILE): New problem codes.
* unix.c (e2fsck_simple_progress), e2fsck.h: New function which
can be called to provide specialized progress bars that
are not related to the top-level pass-based completion
percentage.
* pass3.c (e2fsck_adjust_inode_count), e2fsck.h: Export previously
static function.
2003-03-06 <tytso@mit.edu>
* e2fsck.8.in: Fix minor nit in the -C option. (Addresses Debian
bug #173612)
2003-03-01 Theodore Ts'o <tytso@mit.edu>
* Makefile.in, journal.c, unix.c: Use blkid functions to find the
journal from the UUID, and to interpret the device
specification.
* e2fsck.c: Free the blkid_cache when releasing the e2fsck context
structure.
* e2fsck.h: If strnlen is not present, define it as a macro which
calls e2fsck_strlen(). Add prototype for string_copy().
Add blkid_cache to e2fsck context, and make
filesystem_name, device_name, and journal_name be
non-const variables.
* pass1.c, pass2.c: Remove static strnlen function
* util.c (string_copy, e2fsck_strnlen): New functions
2003-01-29 Theodore Ts'o <tytso@mit.edu>
* unix.c (usage): Make descripton -c be a bit more explicit
2003-01-22 Theodore Ts'o <tytso@mit.edu>
* pass1.c (check_blocks): Use the EXT2_I_SIZE macro.
2003-01-02 Theodore Ts'o <tytso@mit.edu>
* unix.c (main): Detect if there is an attempt to run the journal
twice, and abort with an error if this is the case.
(Address IBM Bugzilla bug #1226)
2002-12-18 Theodore Ts'o <tytso@mit.edu>
* pass2.c (strnlen): Provide strnlen if libc doesn't.
2003-11-19 Theodore Ts'o <tytso@mit.edu>
* unix.c (PRS): Print an error if more than one of the -p/-a, -n
or -y options are specified.
2002-11-12 Theodore Ts'o <tytso@mit.edu>
* problem.c: Make HTREE problems PR_PREEN_OK, so that we don't
abort an e2fsck after the filesystem has been mounted
using the 2.4 ext2 codebase.
2002-11-09 Theodore Ts'o <tytso@mit.edu>
* Release of E2fsprogs 1.32
2002-11-08 Theodore Ts'o <tytso@mit.edu>
* Release of E2fsprogs 1.31
2002-11-08 <tytso@snap.thunk.org>
* unix.c (main): Fix a bug where e2fsck could erroneously mark a
filesystem as being valid if it was being checked and it
is interrupted with a ^C. (Bug introduced in e2fsprogs
1.28.)
* unix.c (PRS), journal.c: Set the default level of journal
debugging to be 0, and allow the user to set the level of
journal debugging by using the E2FSCK_JBD_DEBUG
environment variable.
* pass1.c (new_table_block), super.c (check_super_block), swapfs.c
(swap_filesys): Clear EXT2_FLAG_MASTER_SB_ONLY to make
sure the backup superblocks and group descriptors are
updated when we make an important change to the
superblocks and/or group descriptors. (i.e., generating a
UUID, allocating filesystem metadata, or byte-swapping the
filesystem.)
2002-11-07 Theodore Ts'o <tytso@mit.edu>
* e2fsck.h, unix.c (main, check_mount): Fix e2fsck so that it
returns the appropriate exit code, so that the boot
scripts will be told that they need to automatically
reboot.
2002-10-31 Theodore Ts'o <tytso@mit.edu>
* Release of E2fsprogs 1.30
2002-10-31 Theodore Ts'o <tytso@mit.edu>
* unix.c (usage), e2fsck.8.in: Add the -D option to the usage and
command synopsis. (Addresses Debian bug #167108)
* pass1.c (e2fsck_pass1): Check the superblock write time to see
whether or not we can safely do the LOW_DTIME checks.
(Addresses Sourceforge bug #620980)
2002-10-30 Theodore Ts'o <tytso@mit.edu>
* Makefile.in (install): Search all compression extensions when
deleting old man pages.
* pass1.c (mark_table_blocks): Fix bug in meta_bg support; only
mark blocks legacy group descriptor blocks up to
s_first_meta_bg.
2002-10-20 Theodore Ts'o <tytso@valinux.com>
* pass1.c (mark_table_blocks): Add support for the meta_blockgroup
filesystem format.
2002-10-13 Theodore Ts'o <tytso@mit.edu>
* pass3.c (e2fsck_get_lost_and_found): Pass in mode 700 to
ext2fs_new_inode().
* unix.c (show_stats): Fix format bug if NLS is in use.
* journal.c, pass1.c, revoke.c, util.c: Fix gcc -Wall nits.
2002-10-08 Theodore Ts'o <tytso@mit.edu>
* pass3.c (e2fsck_get_lost_and_found): Create the lost+found
directory with mode 0700.
2002-10-02 Theodore Y. Ts'o <tytso@mit.edu>
* pass2.c (parse_int_node, check_dir_block): Add byte-swap
functions around the htree code, so that it works on
big-endian machines.
* swapfs.c (swap_filesys): For PPC machines, byte-swap the bitmap,
since PPC big-endian filesystems were historically wierd.
This is just for the regression test, since no one
actually uses them anymore...
2002-09-30 Theodore Ts'o <tytso@mit.edu>
* problem.c, problem.h (PR_2_HTREE_BAD_LIMIT,
PR_2_HTREE_BAD_COUNT, PR_2_HTREE_HASH_ORDER,
PR_2_HTREE_BAD_DEPTH): Add new problem codes.
* pass2.c (salvage_directory, check_dir_block): Avoid counting
directory entries twice during a directory salvage. Make
the salvaging algorithm smarter about directory entry size
overruns.
(parse_int_node): Add check to make sure the limit and
count fields in the node headers are sane. Also check
to make sure the hash table in ascending order.
(pass2, htree_depth): For all leaf nodes, determine their
depth in the tree, and make sure it matches with the depth
in the htree root information.
2002-09-29 Theodore Ts'o <tytso@mit.edu>
* pass2.c (check_dir_block): Do a more paranoid check when trying
to determine whether or not a directory entry is a
completely empty leaf block or leaf node. Otherwise
e2fsck might get confused into thinking that a valid dxdir
was corrupted.
* rehash.c (e2fsck_rehash_dir): Apply patch from Christopher Li
which avoids creating an empty directory entry at the end
of the directory block. This screws up earlier versions
of the indexed directory patch.
2002-09-28 Theodore Ts'o <tytso@mit.edu>
* rehash.c (write_directory): Clear the index flag if by
reoptimizing the directory, we bring it back into a
non-indexed state.
(e2fsck_rehash_dir): Allow directories that contain two
blocks to be indexed. Otherwise when they grow, they
never will be indexed by the kernel.
* unix.c (main): Only update the master superblock; there's no
point updating the backup superblocks, and it speeds up
fsck slightly.
* pass2.c (salvage_directory): New function called by
check_dir_block() which is much more sophisticated about
how it salvages corrupted filesystems.
2001-09-24 Theodore Tso <tytso@mit.edu>
* Release of E2fsprogs 1.29
2002-09-06 Theodore Ts'o <tytso@mit.edu>
* rehash.c (copy_dir_entries): Fix bug which caused corrupted
directories if there are 4 or 8 bytes left over in a
directory page when optimizing/reindexing a directory.
2001-08-31 Theodore Tso <tytso@thunk.org>
* Release of E2fsprogs 1.28
2002-08-31 Theodore Ts'o <tytso@mit.edu>
* ehandler.c (e2fsck_handle_read_error): If the user asks to
ignore the error, offer to try forcing a write of the
block to the disk; sometimes this will cause the drive to
remap the bad block.
2002-08-31 Theodore Ts'o <tytso@valinux.com>
* pass2.c (e2fsck_pass2): If this is a HTREE directory, sort the
dblist so that the first block of all of the directories
is handled first so we can read the hash version
information.
(check_dir_block): Examine the root node for correctness,
and offer to clear it if it is not correct. Also copy the
hash version to the dx_dir structure, so that the proper
hash function can be used for other blocks in the
directory.
* problem.c, problem.h (PR_2_HTREE_BAD_ROOT): Add new problem code.
2002-08-21 Theodore Ts'o <tytso@mit.edu>
* problem.c: Fix PR_1_RELOC_BLOCK_ALLOCATE message to explain that
it is necessary to find contiguous blocks in a particular
block group.
2002-08-17 Theodore Ts'o <tytso@mit.edu>
* e2fsck.8.in: Add clarifying text describing how e2fsck works
with ext3 filesytems. (Addresses Debian bug #145044).
* pass1.c (handle_htree): Add support for EXT2_HASH_TEA
* e2fsck.h, e2fsck.c (e2fsck_allocate_context): Add new field to
the e2fsck context, ext_attr_ver, which specifies the EA
format version.
* unix.c (usage, parse_extended_opts, PRS), e2fsck.8.in: Add new
option -E, which allows the users to specify extended
options. Added ea_ver extended option.
* pass1.c (e2fsck_pass1_check_device_inode): Add ext2_filsys
argument to this function, so we can account for the
presence of extended attribute blocks attached to device
inodes.
(e2fsck_pass1_check_symlink, e2fsck_pass1): Take into
account the fact that symlinks can also have extended
attribute blocks.
(check_ext_attr): Don't be flexible about the EA format
version. Check against the version number in
ctx->ext_attr_ver.
(check_blocks): Check all inodes, so that we account for
extended attribute blocks belonging to special files.
Clean up i_size checks.
* pass1b.c (pass1b): Check all inodes, so that we account for
extended attribute blocks belonging to special files.
(delete_file_block): Use ext2fs_alloc_block_stats() to
update the filesystem statistics.
(delete_file): Attempt to decrement the extended
attribute refcount, and free the EA block if the count
hits zero.
(clone_file): Fixed bugs in EA handling. Don't call
block_iterate on inodes that don't have a valid i_block[]
array. Reread the base inode since it may have been
changed by ext2fs_block_iterate. When updating inodes as
part of cloning an EA block, write out the correct inode
structure.
* pass2.c (deallocate_inode_block, deallocate_inode): Use standard
ext2fs_alloc_*_stats functions to update the filesystem
statistics.
(deallocate_inode): Attempt to decrement the extended
attribute refcount, and free the EA block if the count
hits zero.
(e2fsck_process_bad_inode): Add extra argument to calls
to e2fsck_pass1_check_device_inode ().
* pass3.c (e2fsck_get_lost_and_found): Use standard
ext2fs_alloc_*_stats functions to update the filesystem.
statistics when creating /lost+found.
(adjust_inode_count): Remove debugging code that can never
be triggered.
* pass4.c (disconnect_inode): Add explanation about why we only
clear inodes that have no data blocks and no EA blocks.
Use ext2fs_inode_alloc_stats2 function to update the
filesystem statistics when clearing a zero-length inode.
* problem.c, problem.h (PR_1B_ADJ_EA_REFCOUNT,
PR_2_ADJ_EA_REFCOUNT): Add new problem codes.
* super.c (release_inode_block), (release_orphan_inodes): Use the
standard ext2fs_alloc_*_stats functions to update the
filesystem statistics.
(release_inode_blocks): Attempt to decrement the extended
attribute refcount, and free the EA block if the count
hits zero.
2002-08-01 Theodore Ts'o <tytso@mit.edu>
* dict.c, dict.h: New file from kazlib 1.20 which implements a
red-black tree
* pass1b.c: Massive changes to take advantage of dict.c. This
removes several O(n**2) algorithms from the rare case
where there are a large number of blocks claimed by
multiple inodes.
2002-07-24 Theodore Ts'o <tytso@mit.edu>
* e2fsck.8.in, e2fsck.h, pass3.c (e2fsck_pass3), unix.c, rehash.c:
Add new option -D, which requests e2fsck to optimize all
directories. Rehash.c will also compress and sort
non-indexed directories.
* problem.c, problem.h: Rename PR_3A_REHASH_* to PR_3A_OPTIMIZE_*
* unix.c (PRS): Make sure the signal_cancel is registered without
SA_RESTART.
* rehash.c (e2fsck_rehash_dir, copy_dir_entries, calculate_tree):
Restructured code in e2fsck_rehash_dir into two new
subroutines to make the code more understandable/maintainable.
(set_root_node): Fixed bug which caused the root node to
be invalid on non-FILETYPE filesystems due to an
unitialized variable.
(calculate_tree): Fix bug where pointers which might get
invalidated if realloc() moves outdir->buf around.
(e2fsck_rehash_dir): Fix memory leak bug.
* pass3.c (e2fsck_get_lost_and_found), e2fsck.h, e2fsck.c:
Exported as a public interface a function for finding the
lost and found directory. Cache the location of the lost
and found directory in the e2fsck context structure.
* util.c (ask_yn, read_a_char): Note when the user has typed ^C,
and abort processing by longjmp'ing to ctx->abort_loc.
2002-07-23 Theodore Ts'o <tytso@mit.edu>
* pass1.c (e2fsck_pass1): If e2fsck is run with -n, don't create
the dirs_to_hash list, since we don't want to reindex
directories if the filesystem is opened read-only.
2002-07-21 Theodore Ts'o <tytso@mit.edu>
* e2fsck.8.in: Document new exit code FSCK_CANCELED
* unix.c (PRS, signal_cancel): Capture SIGINT and SIGTERM signals
and set a flag in the e2fsck context indicating that
cancellation has been requested, so that e2fsck will exit
only at safe points.
(main): Change the exit handling so that if a cancellation
is requested, return FSCK_CANCELED (a new exit code 32).
e2fsck can now return more than one exit code as part of a
bitmask (as had been documented in the man page).
* pass2.c (e2fsck_pass2, check_dir_block), pass3.c (e2fsck_pass3),
pass4.c (e2fsck_pass4): Check to see if a cancellation was
requested, and abort processing if necessary.
2002-07-19 Theodore Ts'o <tytso@mit.edu>
* rehash.c, Makefile.in: New file which rewrites directories using
the htree format.
* problem.c (fix_problem), problemP.h (PR_PREEN_NOHDR): Add option
which suppresses the header printed when in preen mode.
* pass3.c (e2fsck_pass3): If there are entries on the dirs_to_hash
list, call e2fsck_rehash_directories to reindex those
directories.
(e2fsck_expand_directory): Generalize the old
expand_dirctory() function so it can expand a directory to
a guaranteed minimum size.
* e2fsck.h (struct e2fsck_struct): Add the dirs_to_hash list. Add
new function prototypes for rehash.c and for
e2fsck_expand_directory().
* e2fsck.c (e2fsck_reset_context): Free the dirs_to_hash list.
* pass1.c (e2fsck_pass1): Initialize the dirs_to_hash list if the
htree feature is present in the filesystem.
(check_blocks): If a non-htree directory has more than 2
blocks, put it on the dirs_to_hash list.
* pass2.c (clear_htree): Add corrupt htree directories to the
dirs_to_hash list.
* problem.h, problem.c (PR_3A_PASS_HEADER, PR_3A_REHASH_ITER,
PR_3A_REHASH_DIR_ERR, PR_3A_REHASH_DIR_HEADER,
PR_3A_REHASH_DIR, PR_3A_REHASH_DIR_END): Add new problem codes
* pass2.c (parse_int_node), problem.c (PR_2_HTREE_BADBLK): Fix
problem display.
2002-07-15 Theodore Ts'o <tytso@mit.edu>
* pass2.c (e2fsck_pass2): Use dx_dir->numblocks instead of
dx_dir->ino to indicate that a bad inode was cleared.
2002-06-26 Theodore Ts'o <tytso@mit.edu>
* pass1.c (check_blocks): Move htree handling to handle_htree().
Factor out calls to ext2fs_write_inode so that it happens
if dirty_inode is non-zero.
(handle_htree): Add checks for invalid htree root, invalid
hash version, invalid hash version, and htree depth too deep.
* problem.h, problem.c (PR_1_HTREE_NODIR, PR_1_HTREE_BADROOT,
PR_1_HTREE_HASHV, PR_1_HTREE_INCOMPAT, PR_1_HTREE_DEPTH):
Add new problem codes.
* pass2.c (parse_int_node): Fix silly typo.
(check_dir_block): Change to use new ext2fs_dirhash()
function prototype.
(pass2): Fixed two minor bugs discovered by the test case:
Don't stop checking dxdir's after clearing a bad inode.
If there is a bad max hash, make sure the bad_dir flag
is set to make sure we try to clear inode.
2002-06-25 Theodore Ts'o <tytso@mit.edu>
* e2fsck.c (e2fsck_reset_context): Free the dx_dirinfo structure.
* message.c: Add new abbrevations @h and @p, "HTREE directory
inode" and "problem in".
* pass1.c (check_blocks): If the inode has the INDEX_FL flag,
register the block into the indexed directory data
structures. Or if the filesystem doesn't have the
DIR_INDEX flag, offer to clear the INDEX_FL.
* pass2.c (e2fsck_pass2, parse_int_node): Add support check htree
directories (we don't check all possible corruptions yet).
* problem.h, problem.h (PR_1_HTREE_SET, PR_2_HTREE_NOTREF,
PR_2_HTREE_DUPREF, PR_2_HTREE_MIN_HASH, PR_2_HTREE_MAX_HASH,
PR_2_HTREE_CLEAR, PR_2_HTREE_FCLR, PR_2_HTREE_BADBLK): Add
new problem codes.
* unix.c (main): If ENABLE_HTREE is not defined, complain if the
filesystem has the dir_index feature.
* Makefile.in, e2fsck.h, dx_dirinfo.c: New file (and group of
functions) which keeps track of blocks in HTREE directory
blocks.
2002-05-22 Andreas Dilger <adilger@clusterfs.com>
* super.c (check_superblock): Check that the number of inodes and
blocks in a group is less than 2^16, so that the free inode
and block counts for a group fit into the group descriptor
table fields. Any more than that would need a COMPAT flag.
2002-05-22 Theodore Ts'o <tytso@mit.edu>
* pass1.c (check_ext_attr): Update to support the V2 Bestbits EA
format. We automatically determine from the first EA
block we visit whether we are using the V1 or V2 format.
2002-05-21 Theodore Ts'o <tytso@mit.edu>
* pass1.c (process_block): If an inode has too many blocks or
is too big, then offer to truncate the inode.
(check_blocks): Don't bother checking the size to see if
it's too big, since that's just a symptom, not the disease
(which we're now appropriately checking in process_block).
* problem.c, problem.h: Add new problem codes PR_1_INODE_TOOBIG,
PR_1_TOOBIG_DIR, PR_1_TOOBIG_REG, PR_1_TOOBIG_SYMLINK, and
add the latch code PR_LATCH_TOOBIG.
2002-05-20 Theodore Ts'o <tytso@mit.edu>
* e2fsck.h, pass1.c (e2fsck_pass1_check_symlink), pass2.c
(e2fsck_process_bad_inode): Add an extra
argument so a scratch buffer can be passed into the
function.
* pass1.c (e2fsck_pass1_check_device_inode,
e2fsck_pass1_check_symlink): If the EXT2_INDEX_FL flag is
set, then the device/FIFO is invalid.
(check_immutable): Don't check for EXT2_INDEX_FL; we take
care of that elsewhere now.
(e2fsck_pass1): Check to see if the symlink is valid
before we offer to clear any immutable bits. This matches
the order in which we check other special files.
* pass2.c (e2fsck_pass2): Allocate a bigger scratch buffer so we
can pass part of it to e2fsck_process_bad_inode.
* pass4.c (e2fsck_pass4): If we need to call
e2fsck_process_bad_inode(), allocate the necessary scratch
buffer.
* problem.h, problem.c: Change PR_2_SYMLINK_SIZE to be
PR_2_INVALID_SYMLINK, and change the text
accordingly. Revert the text change for PR_1_SET_IMMUTABLE
since we no longer check for EXT2_INDEX_FL in
check_immutable().
2002-05-18 Andreas Dilger <adilger@clusterfs.com>
* pass1.c (e2fsck_pass1_check_symlink): Remove checks of
immutable/append-only checks, since this is handled by
check_immutable. For non-fast symlinks, read in the
data block and check the length to make sure it
matches with the inode size.
(check_immutable): Generalize to also check for the
EXT2_INDEX_FL flag.
(check_blocks): For non-regular files, signal a bad inode
size if i_size_high is non-zero.
* pass2.c: Only count large files if they are regular files
(not just if they aren't directories).
* problem.c, problem.h: Change comment for PR_2_SYMLINK_SIZE
to indicate that it can be triggered by any symlink,
not fast symlink. Change text for PR_1_SET_IMMUTABLE
to indicate that it the EXT2_INDEX_FL was set.
2002-05-17 Theodore Ts'o <tytso@mit.edu>
* pass1.c (e2fsck_pass1): When calculating max_sizes, omit capping
this value by the calculated value of max_sect_sizes.
The inode may be a sparse inode, and the limit of
max_sect_sizes assumed a non-sparse inode and a limit
based on a 32-bit i_blocks field measured in 512 sectors.
* super.c (check_super_block): Fix check for s_log_block_size so
that takes into account fact that there is an offset of
EXT2_MIN_BLOCK_LOG_SIZE.
* pass1.c: Allocate max_sizes array to be big enough to support
the larger block sizes.
2002-05-16 Andreas Dilger <adilger@clusterfs.com>
* unix.c (main), util.c (get_backup_sb): Use EXT2_MAX_BLOCK_SIZE
instead of using a hardcoded value of 4096.
* super.c (check_super_block): Change checks for s_log_block_size
s_log_frag_size so they support the larger block sizes.
* pass1.c (e2fsck_pass1): Calculate max_sizes array for block
sizes up to EXT2_MAX_BLOCK_SIZE (to support block sizes
greater than 4k).
2002-03-08 Theodore Tso <tytso@mit.edu>
* Release of E2fsprogs 1.27
2002-03-07 Theodore Tso <tytso@mit.edu>
* journal.c, pass5.c, revoke.c: Fix gcc -Wall complaints
2002-03-07 Theodore Tso <tytso@mit.edu>
* unix.c (main): Don't close the filesystem before calling
fatal_error(); this just causes a needless warning about a
bad I/O manager magic number.
* journal.c (e2fsck_check_ext3_journal): Offer to clear the inode
in case the journal is too small, or the inode number in
the superblock doesn't appear to be random.
2002-03-06 Theodore Tso <tytso@mit.edu>
* problem.h, problem.c: PR_5_BLOCK_RANGE_UNUSED,
PR_5_BLOCK_RANGE_USED, PR_5_INODE_RANGE_UNUSED,
PR_5_INODE_RANGE_USED: Add new problem codes.
* pass5.c (check_block_bitmaps, check_inode_bitmaps): Collapse
reporting of adjacent blocks and inodes into a range.
2002-03-04 Philipp Thomas <pthomas@suse.de>
* unix.c (main): Newer libintl needs LC_CTYPE to be set in
addition to LC_MESSAGES.
2002-02-24 Theodore Tso <tytso@mit.edu>
* Makefile.in (install): Install hard links for man pages for
fsck.ext2 and fsck.ext3. Remove any compressed man
pages before installing the man pages.
2002-02-22 Theodore Tso <tytso@mit.edu>
* journal.c: Improve code maintainability and reduce code size by
moving common code paths in e2fsck_journal_init_dev() and
e2fsck_journal_init_inode() into e2fsck_get_journal().
Also fixed a memory leak in recover_ext3_journal().
* super.c (release_orphan_inodes): Fix memory leak.
2002-02-03 Theodore Tso <tytso@thunk.org>
* Release of E2fsprogs 1.26
2001-12-24 Theodore Tso <tytso@mit.edu>
* unix.c (PRS): Don't allow the -c and -l/-L options to be
specified at the same time.
* e2fsck.h (E2F_OPT_WRITECHECK), unix.c (PRS),
badblocks.c (read_bad_blocks_file): If two -c options are
specified, then perform a non-destructive read/write scan
of the disk.
* e2fsck.8.in: Document the double -c option; also encourage users
to use -c instead of the -l/-L options since it's too hard
for users to get things like the blocksize parameter correct.
2001-12-23 Theodore Tso <tytso@mit.edu>
* util.c (get_backup_sb): This function now searches for the
backup superblock by iterating over possible blocksizes
instead of defaulting a guess of 8193 if the superblock
isn't available.
* message.c (expand_percent_expression), unix.c (main): Pass in
new parameters to get_backup_sb. Also, in unix.c, use the
blocksize paramter in the e2fsck context structure instead
of using a static variable, since get_backup_sb wants to
be able to set the blocksize paramter.
* e2fsck.h: Update function prototype for get_backup_sb; also add
the blocksize parameter to the e2fsck context structure.
* Makefile.in, jfs_user.h: Move linux/jbd.h to
ext2fs/kernel-jbd.h, to avoid using the system header
file version of hbd.h when using diet glibc (since it
forcibly adds /usr/include to the beginning of the
include search path.)
2001-12-21 Theodore Tso <tytso@mit.edu>
* problem.c (fix_problem): Use ctx->filesystem_name if the
ctx->device_name is NULL.
* journal.c (e2fsck_check_ext3_journal): Give the opportunity to
run the journal even if recovery flag is cleared. If
we're using a backup superblock, run the journal by
default.
* e2fsck.h (E2F_OPT_FORCE), unix.c (PRS, check_if_skip): Use a
bitfield in the e2fsck context flags word to indicate
whether or not a check should be forced. This allows the
journal code to set the option if necessary to force a
filesystem check.
* problem.h, problem.c: Remove PR_0_JOURNAL_RESET_JOURNAL, and add
PR_0_JOURNAL_RUN and PR_0_JOURNAL_RUN_DEFAULT. Update
problem decription texts.
2001-12-16 Theodore Tso <tytso@mit.edu>
* e2fsck.h (ext2fs_get_refcount_size), unix.c (check_mount, PRS),
pass1.c (adjust_extattr_refcount),
ea_refcount.c (ea_refcount_create): Fix gcc -Wall nits.
* recovery.c, revoke.c: Update to versions from 2.4.17-pre8.
* journal.c, jfs_user.h: Update support code for new version of
recover.c and revoke.c. Fix support for filesystems with
external journals.
2001-11-30 Gabriel Paubert <paubert@iram.es>
* journal.c (e2fsck_journal_load): Fix an endianness bug.
2001-11-26 Theodore Tso <tytso@mit.edu>
* super.c (check_super_block): Make sure that if the inode table
or allocation bitmap is zero, that it is marked as
invalid, so that in pass #1, a new bitmap/inode table gets
properly allocated. (Addresses Debian Bug #116975)
2001-11-24 Theodore Tso <tytso@mit.edu>
* e2fsck.8.in: Fix minor typo in man page and clarify device
specification.
2001-10-07 Theodore Tso <tytso@mit.edu>
* journal.c (clear_v2_journal_fields, e2fsck_journal_load): If the
V2 fields are set on a V1 journal superblock, or an
internal V2 journal has s_nr_users is non-zero, clear the
entire journal superblock beyond the V1 superblock. This
fixes botched V1->V2 updates.
* problem.c, problem.h (PR_0_CLEAR_V2_JOURNAL): Add new problem code.
2001-09-20 Theodore Tso <tytso@mit.edu>
* e2fsck.h, journal.c (e2fsck_move_ext3_journal): Add new function
which will automatically relocate the ext3 journal from a
visible file to an invisible journal file if the
filesystem has been opened read/write.
* super.c (check_super_block): Add call to e2fsck_move_ext3_journal
* problem.c, problem.h (PR_0_MOVE_JOURNAL, PR_0_ERR_MOVE_JOURNAL):
Add new problem codes.
2001-09-20 Theodore Tso <tytso@thunk.org>
* Release of E2fsprogs 1.25
2001-09-19 Theodore Tso <tytso@mit.edu>
* unix.c (main): If a superblock is specified explicitly by the
user, don't try to automatically fall back to an
alternate superblock.
2001-09-02 Theodore Tso <tytso@thunk.org>
* Release of E2fsprogs 1.24a
2001-08-30 Theodore Tso <tytso@thunk.org>
* Release of E2fsprogs 1.24
2001-08-30 Theodore Tso <tytso@valinux.com>
* pass1.c (e2fsck_pass1): For EXT2_RESIZE_INO, allow its i_mode to
either be zero or a regular file (for compatibility with
Andreas's on-line resizing programs).
2001-08-27 Theodore Tso <tytso@valinux.com>
* unix.c (main): Remove EXT2FS_VERSION from the version display,
since it only confuses people.
* pass1.c (strnlen): Provide strnlen if libc doesn't.
2001-08-15 Theodore Tso <tytso@valinux.com>
* Release of E2fsprogs 1.23
2001-08-13 Theodore Tso <tytso@valinux.com>
* super.c (release_orphan_inodes): If the filesystem contains
errors, don't run the orphan * list, since the orphan list
can't be trusted.
* pass1.c (check_size): Fix logic in check_size; the previous code
only offered to clear the inode size fields if both size
and i_size_high were zero.
(e2fsck_pass1_check_device_inode): If i_blocks is
non-zero, then assume that the device/socket/fifo inode
is bogus.
2001-08-09 Theodore Tso <tytso@valinux.com>
* pass1.c, pass2.c, problem.c, problem.h: Fix bug introduced by
Andreas's symlink code; check_blocks() was unconditionally
testing inode_bad_map without checking to see if it
existed first. Fixed problem a different way; we now no
longer check inode_bad_map at all, since the file might
not get deleted in pass 2 anyway. We move the large file
feature reconciliation code to to e2fsck_pass2(), and in
deallocate_inode() in pass2.c, we decrement the large
files counter if we're about to delete a large file.
* unix.c (show_stats): Print the number of large files in verbose
mode.
2001-08-07 Theodore Tso <tytso@valinux.com>
* journal.c (recover_ext3_journal): If s_errno is set in the
journal superblock, set the EXT2_ERROR_FS flag in the
filesystem superblock after the journal is run.
2001-08-04 Andreas Dilger <root@lynx.adilger.int>
* message.c: Change comments for %D and %d expansion in e2fsck
problem codes. It was not consistent which was for dirent
expansion, and which was for directory number expansion.
* problem.c (PR_2_FINAL_RECLEN, PR_2_BAD_FILETYPE): Fix problem
codes which got caught by the confusion between %D and %d.
2001-08-04 Theodore Tso <tytso@valinux.com>
* problem.c (PR_2_SYMLINK_SIZE): Change description to make it
more clear (and remove %s expansion). Also add missing
periods to the end of a number of problem descriptions.
* pass2.c (e2fsck_process_bad_inode): Remove unneeded problem
context string set now that the problem description for
PR_2_SYMLINK_SIZE has been changed.
* pass1.c (e2fsck_pass1_check_symlink): Consolidate some checks,
and check the validity of the symlink block here (so that
we detect this case here instead of later). Also use
sizeof(inode->i_block) instead EXT2_LINK_DIR.
2001-07-30 Theodore Tso <tytso@valinux.com>
* unix.c (check_mount): Remove the code which tested for the root
filesystem being mounted read-only, and depend on the
results flags from ext2fs_check_if_mounted.
2001-07-29 Theodore Tso <tytso@valinux.com>
* unix.c (check_if_skip): Free the e2fsck context structure on a
normal clean filesystem exit, to make it easier to find
real memory leaks.
(PRS): Only update the path to include /sbin at the
beginning if the -c option is given, again to make it
easier to find memory leaks.
(main): Move the final print_resource_track call after the
filesystem and the context are freed.
* journal.c (e2fsck_journal_init_dev): Avoid memory leak if we
need to search for the journal device.
(e2fsck_journal_release): Free the journal IO channel when
we release the journal handle, to avoid a memory leak.
* e2fsck.c (e2fsck_reset_context): Fix bug; only close the io
channel if it is *different* from the filesystem io
channel.
2001-07-27 Theodore Tso <tytso@valinux.com>
* problem.c (PR_1_SET_IMMUTABLE): Clarify problem message.
* pass1.c (e2fsck_pass1): Check for symlinks that have the
immutable flag set (and offer to clear them).
2001-07-26 Theodore Tso <tytso@valinux.com>
* pass1.c (e2fsck_pass1): Free ctx->block_ea_map at the end of
pass 1.
2001-07-25 Theodore Tso <tytso@valinux.com>
* pass1.c (check_ext_attr): Skip zero-length EA entries.
* problem.c: PR_1_EA_ALLOC_COLLISION shouldn't abort, but should
prompt to clear the EA block.
2001-07-22 Theodore Tso <tytso@valinux.com>
* journal.c (ll_rw_block): Use ctx->journal_io instead of the
filesystem's io_channel.
(e2fsck_journal_init_dev): New function which supports
initialization of the external journal.
(e2fsck_get_journal): Remove code which flagged an error
if the superblock reported the use of an external journal.
(ext3_journal_via_mount): Remove unsued, #ifdefed out function.
* problem.c, problem.h: Removed error codes no longer used
(PR_0_JOURNAL_UNSUPP_DEV, PR_0_JOURNAL_BAD_DEV,
PR_0_JOURNAL_UNSUPP_UUID) and replace them with new error
codes related with failures in loading the external
journal (PR_0_JOURNAL_UNSUPP_MULTIFS,
PR_0_CANT_FIND_JOURNAL, PR_0_EXT_JOURNAL_BAD_SUPER).
Also changed the text assocated with PR_0_JOURNAL_BAD_UUID
to reflect the case where the external journal isn't
correct for this filesystem.
* unix.c (PRS), e2fsck.8.in: Add new option -j which allows
the user to specify the pathname to find the external journal.
* e2fsck.c (e2fsck_reset_context): Close journal_io if it isn't
the same as the filesystem io_channel.
* e2fsck.h: Add new fields (journal_io and journal_name) in the
context structure to support external journals.
2001-07-20 Theodore Tso <tytso@valinux.com>
* unix.c (main): Add an explicit warning when the filesystem is
left not completely fixed when e2fsck exits. (Addresses
Debian bug #104502.)
2001-07-19 Theodore Tso <tytso@valinux.com>
* pass1.c (check_ext_attr): The entire EA block is now checked to
make sure that parts of the EA block aren't being used for
multiple purposes.
* Makefile.in e2fsck.h, region.c: New file which is used to detect
collisions in extended attribute block.
* problem.h, problem.c (PR_1_EA_MULTI_BLOCK, PR_1_EA_ALLOC_REGION,
PR_1_EA_ALLOC_COLLISION, PR_1_EA_BAD_NAME,
PR_1_EA_BAD_VALUE): Add new problem codes.
2001-07-10 Theodore Tso <tytso@valinux.com>
* journal.c (e2fsck_run_ext3_journal): Only call ext3_flush() if
the superblock is dirty.
2001-07-07 Theodore Tso <tytso@valinux.com>
* pass1b.c (pass1b, process_pass1b_block): Change the num_bad
field calculation so that it only counts EA block entries
as a single multiply claimed block (since once we clone
the EA blocks for one inode, we fix the problem for all of
the other inodes). Also, I moved the num_bad calculation
from process_pass1b_block to the end of pass1b. This
fixes a *significant* performance bug in pass1b which hit
people who had to had a lot of multiply claimed blocks.
(Can you say O(n**3) boys and girls? I knew you could...
Fortunately, this case didn't happen that much in actual
practice.)
* pass1.c (e2fsck_pass1): Defer inodes which have an extended
attribute block for later processing to avoid extra seeks
across the disk.
(process_inode_cmp): If there is no indirect block, sort
by the extended attribute (i_file_acl) block.
* pass1b.c (clone_file_block): Fix bugs when cloning extended
attribute blocks. Moved free of block_buf to after the
code which clones the extattr block, and fixed logic for
changing pointers to the extended attribute field in the
inodes which were affected.
(decrement_badcount): New function which is used whenever
we need to decrement the number of files which claim a
particular bad block. Fixed bug where delete_file wasn't
checking check_if_fs_block() before clearing the entry in
block_dup_map. This could cause a block which was claimed
by multiple files as well as the filesystem metadata to
not be completely fixed.
* pass1.c (adjust_extattr_refcount): Add new function which
adjusts the reference counts of extended attribute blocks
if needed, both up and down.
(e2fsck_pass1): If the refcount or refcount_extra
structure are present, call adjust_extattr_refcount(),
and free it afterwards.
* problem.h, problem.c (PR_1_EXTATTR_READ_ABORT,
PR_1_EXTATTR_REFCOUNT, PR_1_EXTATTR_WRITE): Add new
problem codes.
2001-07-02 Theodore Tso <tytso@valinux.com>
* pass1.c (e2fsck_pass1, check_ext_attr, check_blocks): Add
initial support for scanning extended attribute blocks.
* e2fsck.c (e2fsck_reset_context): free extended attribute
refcount structure.
* e2fsck.h: Add new fields for accounting for the extended
attribute blocks.
* Makefile.in, ea_refcount.c, e2fsck.h: Add new file which
implements a reference count abstraction.
* problem.c, problem.h: Add new problem codes PR_1_ALLOCATE_REFCOUNT,
PR_1_READ_EA_BLOCK, PR_1_BAD_EA_BLOCK, PR_2_FILE_ACL_BAD
* message.c: Add "@a" as an abbreviation for "extended attribute"
* pass1b.c (clone_file): Add code which handles cloning an
extended attribute block.
* pass1b.c (delete_file):
* pass2.c (deallocate_inode): If the inode contains an extended
attribute block in the file_acl field, clear it and
deallocate the block.
2001-06-28 Theodore Tso <tytso@valinux.com>
* pass2.c (e2fsck_process_bad_inode): Deal with inodes which are
marked bad because of an invalid file_acl (either because
EXT2_FEATURE_COMPAT_EXT_ATTR is not set, or because the
block number in file_acl is bad.
2001-06-29 Theodore Tso <tytso@valinux.com>
* unix.c (show_stats): Use long long to calculate the percentage
of the number of blocks in use in the filesystem.
2001-06-23 Theodore Tso <tytso@valinux.com>
* Release of E2fsprogs 1.22
2001-06-22 Theodore Tso <tytso@valinux.com>
* flushb.c: Use platform independent method of defining the
BLKFLSBUF ioctl. Also include sys/mount.h since on newer
platforms BLKFLSBUF is defined there.
2001-06-19 Theodore Tso <tytso@valinux.com>
* super.c (release_inode_blocks): Don't try to release the blocks
if the orphaned inode is a device file, symlink, or some
other kind of special file that doesn't have a block list.
2001-06-15 Theodore Tso <tytso@valinux.com>
* Release of E2fsprogs 1.21
2001-06-13 Theodore Tso <tytso@valinux.com>
* unix.c (check_if_skip): Adapted patch from Andreas Dilger which
prints the number of mounts or days elapsed since the last
check when e2fsck is forced to check an otherwise clean
filesystem.
2001-06-12 Theodore Tso <tytso@valinux.com>
* badblocks.c: Stop using the compatibility badblocks function,
and use the ext2fs_badblocks_* functions instead.
2001-06-11 Theodore Tso <tytso@valinux.com>
* unix.c (PRS): Fix bug introduced in 1.20 which broke the -F
flag.
* Makefile.in: Add message.c and swapfs.c to the list of source
files to build the make depend.
* swapfs.c, unix.c: Only support the -s and -S options to e2fsck
if ENABLE_SWAPFS is defined.
2001-06-08 Theodore Tso <tytso@valinux.com>
* recover.c, revoke.c: Synchronize with ext3 0.7a
2001-06-02 Theodore Tso <tytso@valinux.com>
* recovery.c (scan_revoke_records): Fix bug in recovery code;
missing byte order conversion.
* pass1.c (mark_inode_bad): Replace alloc_bad_map with a function
which sets the bit in the bad inode bitmap.
(e2fsck_pass1): Check for fast symlinks with an invalid
size, and set the bad inode map in that case.
(check_size): Check i_size_high for special files and
prompt to clear it along with i_size if non-zero.
* pass2.c (e2fsck_process_bad_inode): Check for fast symlinks with
an invalid size and prompt the user if the inode should be
cleared.
* problem.h, problem.c (PR_2_SYMLINK_SIZE): Added new problem code.
2001-06-01 Theodore Tso <tytso@valinux.com>
* problem.c, problem.h: Change PR_0_JOURNAL_UNSUPP_INCOMPAT and
PR_0_JOURNAL_UNSUPP_ROCOMPAT so they aren't fatal errors,
but prompt to see if the user should abort. Removed the
PR_0_JOURNAL_RESET_COMPAT problem code.
* journal.c (e2fsck_journal_load): If there are incompatible
journal flags, just return an error code.
(e2fsck_check_ext3_journal): If e2fsck_journal_load
returns an error code indicating that there are
incompatible journal flag, check to see if we should
abort, and then offer to clear the journal.
(Addresses Debian bug #98527.)
* Makefile.in: Move include/asm/types.h.in to
lib/ext2fs/ext2_types.h.in.
2001-06-01 Theodore Tso <tytso@valinux.com>
* pass1.c (pass1_get_blocks, pass1_read_inode, pass1_write_inode,
pass1_check_directory): Add a safety check to make sure
ctx->stashed_inode is non-zero.
* pass1b.c (pass1b): Use e2fsck_use_inode_shortcuts() to disable
the inode shortcut processing, instead of manually
clearing only half of the function pointers that needed to
be NULL'ed out. This caused nasty bugs if the last inode
in the filesystem needed dup block processing.
* pass1b.c (clone_file_block): When cloning a directory's metadata
block, don't try to update the directory block list
database, since indirect blocks aren't stored in the
database and the resulting error will abort the file clone
operation.
2001-05-25 Theodore Tso <tytso@valinux.com>
* Release of E2fsprogs 1.20
2001-05-25 Theodore Tso <tytso@valinux.com>
* journal.c (e2fsck_journal_reset_super): Remove extraneous line
2001-05-23 Theodore Tso <tytso@valinux.com>
* journal.c (e2fsck_journal_reset_super): Fix bug; the reset
journal wasn't getting written out to disk since the dirty
bit wasn't being set on the buffer.
(e2fsck_journal_load): Don't print an error message if the
journal version number is wrong; just return a error code
reflecting this fact. If the block type in the journal
superblcok is obviously not a version number, report the
journal is corrupted.
(e2fsck_check_ext3_journal): On an unsupported journal
version, prompt to abort by default, but then offer a
chance to clear the journal as corrupt.
* problem.c, problem.h (PR_0_JOURNAL_UNSUPP_VERSION): Added new
problem code.
2001-05-14 Theodore Tso <tytso@valinux.com>
* pass1.c: Treat inodes with a low dtime (that were from a
corrupted orphan list) specially.
* problem.c, problem.h: Add new problem codes PR_1_LOW_DTIME and
PR_1_ORPHAN_LIST_REFUGEES, and a new latch group,
PR_LATCH_LOW_DTIME.
* problemP.h: Expand the size of the problem flag to be an int
instead of a short. Expand space in the flag word which
is reserved for problem latch flags from 3 bits to 8 bits.
* e2fsck.h, scantest.c: Change location of ext2_fs.h to be
ext2fs/ext2_fs.h
* super.c (check_super_block): Be more strict on checking
s_r_blocks_count superblock field.
2001-05-13 Theodore Tso <tytso@valinux.com>
* problem.c, problem.h (PR_0_JOURNAL_UNSUPP_ROCOMPAT,
PR_0_JOURNAL_UNSUPP_INCOMPAT, PR_0_JOURNAL_RESET_COMPAT):
New problem codes.
* journal.c (e2fsck_journal_load): Use a problem code to
report unsupported feature flags. There is code to
clear unsupported flags, but since this is dangerous,
it's not allowed in the problem code table.
2001-05-11 Andreas Dilger <adilger@turbolinux.com>
* journal.c (e2fsck_journal_reset_super): initialize the journal
sequence number to a random value to avoid recovering
bad transactions from a corrupt journal.
2001-05-13 Theodore Tso <tytso@valinux.com>
* journal.c: Code cleanup; initialize journal_enable_debug using
an initializer.
2001-05-12 Theodore Tso <tytso@valinux.com>
* unix.c (PRS): Skip validation of -C's file descriptor if it is
zero, since that is special case.
2001-05-09 Theodore Tso <tytso@valinux.com>
* super.c (release_orphan_inodes): Add gettext quoting around
"Truncating" and "Clearing" for i18n.
2001-05-05 Theodore Tso <tytso@valinux.com>
* util.c (fatal_error): Use the correct magic number when checking
the magic number for the io_channel data structure. Also
remove extraneous call to io_channel_flush() that was left
over from an editing session.
* pass2.c (check_dir_block): Ignore EXT2_ET_DIR_CORRUPTED errors
from ext2fs_read_dir_block().
2001-05-01 Theodore Tso <tytso@valinux.com>
* unix.c (PRS): Validate the completion information file
descriptor so that the completion bar won't get
accidentally written onto the disk.
* e2fsck.8.in: Add explanation that you can use mke2fs -n -b
blocksize to printout alternate superblock locations.
2001-04-26 Theodore Tso <tytso@valinux.com>
* unix.c (check_if_skip): If the max_mount_count is zero, treat it
as having no count set.
2001-04-16 Theodore Tso <tytso@valinux.com>
* super.c (check_super_block): Fix bad calculation of
inodes_per_block, and tighten min/max checks to be a bit
more paranoid. Thanks to Andreas Dilger for pointing out
this bug.
2001-03-29 Theodore Tso <tytso@valinux.com>
* journal.c (mark_buffer_uptodate): Add emulation of kernel
function mark_buffer_uptodate.
* recovery.c, revoke.c: Synchronize with 0.6b ext3 files.
2001-02-12 Theodore Tso <tytso@valinux.com>
* journal.c (e2fsck_run_ext3_journal): Force a flush of the
filesystem and io_channel before replaying the journal.
2001-01-17 Theodore Ts'o <tytso@valinux.com>
* pass1.c (check_blocks): Fix large file checking code so that
files > 2GB are considered large files, and restrict
directories from being > 2GB.
2001-01-12 Theodore Ts'o <tytso@valinux.com>
* journal.c (e2fsck_journal_fix_unsupported_super): Remove unused
function. Add FIXME notes to e2fsck_get_journal(), from
Andreas Dilger.
* pass1.c (e2fsck_pass1): Cap the maximum legal size of a file by
the limit caused by the fact that i_blocks is in 512 byte
units, and that the Linux buffer cache also fundamentally
assumes 512 byte sectors.
Make sure that the journal inode is a regular file, and
when clearing an unused journal inode, make sure the
icount db is updated.
* problem.c, problem.h (PR_1_JOURNAL_BAD_MODE): Add new problem code.
* problem.c: For PR_1_RESERVED_BAD_MODE, print a description of
the reserved inode. In PR_0_JOURNAL_HAS_JOURNAL, prompt
to clear the journal, rather than deleting it (which is
more accurate). (From Andreas Dilger.)
* journal.c: Make sure all functions which return an error code
use the errcode_t return type, and not "int"
(e2fsck_journal_release): Add new parameter, "drop",
which is used when we just want to deallocate the journal
without trying to write out any changes.
(mark_buffer_clean): New function
(e2fsck_check_ext3_journal): If we fail loading the
journal, make sure we free all memory associated with it.
(recover_ext3_journal): If we fail to load the journal or
initialize the revoke data structures, make sure we free all
memory associated with the journal.
* message.c (special_inode_name): Add more special inode names
(From Andreas Dilger)
* util.c (fatal_error): Check to make sure the io_manager data
structure is sane before trying to flush the io_channel.
(From Andreas Dilger)
* mtrace.h, super.c, pass2.c: Minor whitespace cleanups, from
Andreas Dilger.
* journal.c (e2fsck_journal_fix_bad_inode): Set pctx->ino to the
bad journal number.
* problem.c (PR_0_JOURNAL_BAD_INODE): Use pctx->ino instead of
pctx->num when printing the bad journal inode number.
2001-01-11 <tytso@snap.thunk.org>
* pass1.c (process_block): Remove dead code which was never
getting executed.
* iscan.c, unix.c, e2fsck.h: Don't use NOARGS, and use
ext2fs_sync_device() instead of using BLKFLSBUF.
* flushb.c: Don't use NOARGS anymore; everything is STDC these days.
* dirinfo.c, e2fsck.h, emptydir.c, iscan.c, jfs_user.h, journal.c,
message.c, pass1.c, pass1b.c, pass2.c, pass3.c, pass4.c,
pass5.c, problem.h, scantest.c, super.c, swapfs.c: Change
ino_t to ext2_ino_t.
2001-01-09 <tytso@snap.thunk.org>
* problem.c: Fix another broken @F vs @f problem.
2001-01-06 <tytso@snap.thunk.org>
* journal.c, pass1.c, pass1b.c, pass3.c, recovery.c, revoke.c,
super.c, unix.c, util.c: Fix random gcc -Wall complaints.
* jfs_user.h: Use more sophisticated inline handling to allow
building with --enable-gcc-wall
2001-01-03 <tytso@snap.thunk.org>
* pass1.c (e2fsck_pass1): Moved journal inode handling out to its
own block; if the journal inode is not in use, and it
contains data, offer to clear it.
* problem.h, problem.c (PR1_JOURNAL_INODE_NOT_CLEAR): Add new
problem code.
* problem.c: Modified problem table to use a new abbreviations.
* message.c: Add @j abbreviation for journal, and @v abbreviation
for device.
* jfs_user.h: Moved contents of jfs_e2fsck.h into jfs_user.h.
* journal.c (e2fsck_check_ext3_journal): Force a fsck if we remove
the journal stored on a reserved inode. Also force a fsck
if the journal appears to exist while !NEEDS_RECOVERY, and
we forcibly reset the journal.
2001-01-01 <tytso@snap.thunk.org>
* journal.c, pass1.c, super.c, unix.c: Replace use of struct
ext2fs_sb with struct ext2_super_block.
* pass1.c (check_blocks): Remove use of EXT2_HAS_*_FEATURE macros.
2000-12-31 <tytso@snap.thunk.org>
* jfs_compat.h: Remove uneeded header file.
2000-12-30 <tytso@snap.thunk.org>
* malloc.h, mtrace.c: Renamed malloc.h to mtrace.h to avoid
conflicts with the system header file.
* problem.h: Fixed numbering of pass1 error messages; an extra 0
had slipped into some of the numbers. (Pointed out by
Andreas Dilger)
* journal.c (e2fsck_journal_fix_corrupt_super): Clean up
unnecessary automatic variable. Add explanatory comment
about the kernel emulation routines. (Suggested by
Andreas Dilger)
2000-12-13 Theodore Ts'o <tytso@valinux.com>
* journal.c (e2fsck_check_ext3_journal): Check to make sure the
journal fields are consistent if any of the superblock
fields are set. (Backs out erroneous change made by sct,
pointed out by Andreas.)
* unix.c (main): Clarify coments (no code changes)
* super.c (release_orphan_inodes): Fix spelling typo in error message.
* pass1.c (e2fsck_pass1): Offer to update the filesystem revision
level if we need to set large files flag. Patch from
Andreas Dilger.
* super.c (check_super_block): If we have any of the compatibility
flags set, we need to have a revision 1 filesystem. Most
kernels will not check the flags on a rev 0 filesystem
and we may have corruption issues because of the
incompatible changes to the filesystem. Patch from Andreas
Dilger.
* problem.c, problem.h (PR_0_FS_REV_LEVEL, PR_1_FS_REV_LEVEL): Add
new problem codes.
2000-12-09 <tytso@snap.thunk.org>
* flushb.c: Fix flushb so that it does something other than waste
disk space when built on systems with modern header files
and add a non-subtle Copyright Licensing restriction so
Yann will remove it from the Debian Distribution. (Now
violates the Debian Free Software Guidelines, on purpose.)
* journal.c (e2fsck_check_ext3_journal): If JFS_DEBUG is defined
at the top level, set the JFS debuging level to 2.
* jfs_e2fsck.h, jfs_user.h: Replaces jfs_compat.h. The jfs.h file
has been moved to the include/linux directory.
* journal.c, revoke.c, recovery.c: Updated files from Stephen to
support the V2 superblock and revoke processing. The
journal.c and revoke.c files are copies from the ext3
kernel source.
* Makefile.in: Added revoke.c to the list of source/object files.
2000-11-16 Theodore Ts'o <tytso@valinux.com>
* pass1b.c: Change routines to use PR_1B_BLOCK_ITERATE when
reporting problems rather than using com_err directly.
* problem.c, problem.h (PR_1B_BLOCK_ITERATE): Add new problem code.
* message.c (expand_percent_expression): Add safety check. If
ctx->str is NULL, print "NULL" instead of dereferencing
the null pointer.
* pass1b.c, pass2.c, pass3.c: Change calls to ext2fs_block_iterate
to ext2fs_block_iterate2, to support 64-bit filesizes and
to speed things up slightly by avoiding the use of the
ext2fs_block_iterate's compatibility shim layer.
2000-10-30 <tytso@snap.thunk.org>
* util.c (get_backup_sb): Calculate backup superblock correctly
when the blocksize is > 1k.
2000-10-26 <tytso@snap.thunk.org>
* jfs.h, jfs_compat.h, journal.c: Updated to include the
definition of the new journal superblock format; still
only supports V1 superblocks for now. (From sct)
2000-10-24 <tytso@snap.thunk.org>
* super.c (release_inode_block, release_inode_blocks,
release_orphan_inodes): Add code to deal with truncating
inodes which are still in use (but which are on the orphan
list because they need truncation).
* problem.c, problem.h: Rename PR_0_CLEAR_ORPHAN_INODE to
PR_0_ORPHAN_CLEAR_INODE, and remove
PR_0_ORPHAN_INODE_INUSE.
* journal.c (e2fsck_run_ext3_journal): Add i18n support, and print
a message when the journal is being recovered.
* pass1.c (e2fsck_pass1): Don't check the i_mode field for the
journal inode, if it is in use.
2000-09-12 <tytso@valinux.com>
* extend.c:
* flushb.c: Add include of nls-enable.h which is necessary so that
they can compile correctly.
2000-08-22 <tytso@valinux.com>
* unix.c (main): If we're doing a read-only check, skip the
journal playback, but don't abort the e2fsck run.
* super.c (release_orphan_inodes): Fix typo; should do bounds
checking on next_ino instead of ino.
* jfs_compat.h (J_ASSERT):
* journal.c (e2fsck_run_ext3_journal):
* pass3.c (adjust_inode_count): Use fatal_error() instead of exit().
* unix.c: Use fatal_error() instead of exit() whenever possible.
Also fix the fsck exit codes so that we use FSCK_USAGE
when it is appropriate. Rename global_signal_ctx to
e2fsck_global_ctx and let it be exported globally.
* util.c (fatal_error): Try to flush the I/O manager before
forcing an exit.
2000-08-20 <tytso@valinux.com>
* journal.c (e2fsck_journal_load): Fix **nasty** bug which caused
e2fsck_check_ext3_journal to smash the journal because
journal->j_transaction_sequence wasn't getting
initialized.
* journal.c: (recover_ext3_journal, e2fsck_run_ext3_journal): Move
call to e2fsck_clear_recover from recover_ext3_journal to
after the filesystem has been closed and reopened.
Otherwise, the superblock in the filesystem handle will
probably be stale, and will overwrite the newer version of
the superblock written by the log recovery.
* message.c (expand_inode_expression): Add support for %Iu and %Ig
* problem.h (PR_0_CLEAR_ORPHAN_INODE): Add new problem code.
* super.c (release_orphan_inodes, release_inode_block,
release_inode_blocks): Update the block group descriptor
counts when freeing the orphan inode. Use
PR_0_CLEAR_ORPHAN_INODE to report when we clear an orphan.
* journal.c (e2fsck_run_ext3_journal): Fix a bug where we
attempted to reopen the filesystem using the device name
instead of the filesystem name.
2000-08-18 <tytso@valinux.com>
* Makefile.in: Update the make dependencies
* problem.c, problem.h: Add the problem codes:
PR_0_ORPHAN_ILLEGAL_BLOCK_NUM,
PR_0_ORPHAN_ALREADY_CLEARED_BLOCK,
PR_0_ORPHAN_ILLEGAL_HEAD_INODE,
PR_0_ORPHAN_ILLEGAL_INODE, PR_0_ORPHAN_INODE_INUSE
* super.c (release_inode_blocks, release_orphan_inodes,
check_super_block): Add support for clearing orphaned
inodes from the unmounted filesystem.
* journal.c (e2fsck_recover_ext3_journal): Remove the last orphan
check; this is now handled in check_super_block ---
non-journaled filesystems can use the orphan list in the
future. Also, move the the re-opening of the filesystem
to e2fsck_run_ext3_journal().
2000-07-12 Andreas Dilger <adilger@turbolinux.com>
* journal.c: implement loading of ext3 journal for recovery code
* problem.c (fix_problem): return answer from PR_AFTER_CODE to caller.
Add journal problems.
* recovery.c (journal_recover): user-space ext3 journal recovery code
* unix.c (main) : check journal and do recovery in separate steps
2000-08-07 <tytso@snap.thunk.org>
* unix.c (calc_percent): Make sure that we don't take a floating
exception if the max value is zero. (should normally
never happen, but...)
2000-07-13 <tytso@valinux.com>
* Release of E2fsprogs 1.19
2000-07-06 Theodore Ts'o <tytso@valinux.com>
* unix.c (check_if_skip): Modify algorithm for checking
s_max_mnt_count to match with the kernel. (If
s_max_mnt_count is negative, ignore the mnt_count check.)
* unix.c (e2fsck_update_progress): Adjust the width of the
progress bar dynamically, based on the filesystem name
that we need to display.
* unix.c (main): If the ext3 needs_recovery flag is set, call
e2fsck_run_ext3_journal() and then restart the e2fsck run.
* journal.c (e2fsck_run_ext3_journal): New file which contains
logic to recover the ext3 journal. This version relies on
the kernel being able to mount the filesystem in order to
run the journal.
2000-07-05 Theodore Ts'o <tytso@valinux.com>
* unix.c (e2fsck_update_progress): Only save and check the last
percentage after multiplying it by 10, nor 1000, since we
only need to save values to a tenth of a percent (and the
percentage is already from 0 .. 100%, not 0 .. 1).
Also, re-arrange the logic so that we do the time
check only after doing the percentage check, and we
only advance the spinner if we're about to display it.
2000-07-04 Theodore Ts'o <tytso@valinux.com>
* pass1.c (e2fsck_pass1): Check to see if the ext3 s_last_orphan
field is set; if so, clear it, so that ext3 mounting code
won't get confused by the fact that we've cleared out the
orphaned inodes.
2000-06-10 Theodore Ts'o <tytso@valinux.com>
* pass5.c (check_block_bitmaps, check_inode_bitmaps): Add error
checking for a "should never happen case".
* problem.c, problem.h (PR_5_COPY_IBITMAP_ERROR,
PR_5_COPY_BBITMAP_ERROR): Add new error codes.
2000-05-27 Theodore Ts'o <tytso@valinux.com>
* pass1.c (pass1, check_size): Apply patch from Chris Wedgewood
(cw@foof.org) which checks to see if special devices have
a non-zero size, and deals with it.
* problem.c, problem.h (PR1_SET_NONZSIZE): Add new problem code.
2000-05-18 Theodore Ts'o <tytso@valinux.com>
* Makefile.in (install): Create a symbolic link for fsck.ext3 as
well.
2000-05-08 Theodore Ts'o <tytso@valinux.com>
* problem.c, problem.h (PR_0_HURD_CLEAR_FILETYPE): Add new problem
code.
* super.c (check_super_block): If the OS type in the superblock is
the Hurd, check to see if the filetype feature is set, and
offer to clear it if so. This needs to be done since the
Hurd doesn't properly support the filetype feature.
(And since the hurd allows the transmogrification of files
to special files and vice versa --- for no good reason
that I can understand --- it can't support the filetype
feature for the forseeable future, either.)
2000-04-03 Theodore Ts'o <tytso@valinux.com>
* unix.c: For platforms that don't define optarg.h, manually
define optarg and optind.
2000-03-20 Theodore Ts'o <tytso@valinux.com>
* pass1.c (check_immutable, e2fsck_pass1_check_device_inode):
Check for the append-only as well as the immutable flag.
* problem.c (PR_1_SET_IMMUTABLE): Adjust message to include
append-only flag. Fix comment for compression flag.
2000-02-12 <tytso@snap.thunk.org>
* unix.c (e2fsck_update_progress): Limit the number of updates to
the progress bars to 8 times a second. This allows a 9600
baud console link to keep up.
2000-02-11 <tytso@snap.thunk.org>
* unix.c (main): If compression is enabled on the filesystem,
print a warning message (for now).
* message.c: Add new compression shortcut: @c == compress
* problem.c, problem.h (PR_1_COMPR_SET): Add new error code.
* pass1.c (check_blocks): If the inode has EXT2_COMPRBLK_FL flag
set, check to see if the filesystem supports compression.
If it does pass this information down to process_block()
so it can treat the compressed block flag words
correctly. If not, offer to clear the flag, since it
shouldn't be set.
(process_block): If an inode has the compressed inode flag
set, allow EXT2FS_COMPRESSED_BLKADDR.
* pass1b.c (process_pass1b_block, delete_file_block,
clone_file_block):
* pass2.c (deallocate_inode_block): Use HOLE_BLKADDR to check to
see if the block can be skipped.
2000-02-08 <tytso@snap.thunk.org>
* util.c: Make resource tracking message more concise.
* e2fsck.h:
* pass1.c (mark_table_blocks, e2fsck_pass1): Remove
ctx->block_illegal_map, since it's not needed by pass1,
and pass1b has been modified to calculate it manually if
needed. This reduces the memory footprint needed by e2fsck.
* pass1b.c (check_if_fs_block): New static function which returns
whether or not a block overlaps with filesystem metadata.
This replaces consulting the block_illegal_map bitmap.
* Makefile.in: Call sync after finishing building all in this
directory.
* unix.c (PRS): sync the filesystem before trying to use
BLKFLSBUF, to minimize the chance of causing dirty blocks
to get dropped.
* e2fsck.h: Manually define BLKFLSBUF if not defined, and we're on
a Linux/i386 system.
* pass3.c (check_directory): Only do the loop detection algorithm
if we've searched over 2048 parent directories and haven't
found the end yet. This means that in the common case, we
don't allocate or clear the inode_loop_detection bitmap,
which for large systems, merely clearing the bitmap for
each directory was turning out to be quite expensive.
Thanks to Jani Jaakkola (jjaakkol@cs.helsinki.fi) for
identifying this problem.
2000-02-06 Theodore Ts'o <tytso@valinux.com>
* badblocks.c, e2fsck.h, ehandler.c, emptydir.c, extend.c,
flushb.c, iscan.c, message.c, pass1.c, pass1b.c, pass3.c
pass4.c, pass5.c, problem.c, scantest.c, swapfs.c,
unix.c, util.c: Add Internationalization support as
suggested by Marco d'Itri <md@linux.it>.
2000-02-02 Theodore Ts'o <tytso@valinux.com>
* e2fsck.h, flushb.c, scantest.c: Remove uneeded include of
linux/fs.h
2000-01-18 Theodore Ts'o <tytso@valinux.com>
* Makefile.in: Since LIBUUID can sometimes include "-lsocket"
we need a separate DEPLIBUUID that can be used in
Makefile's dependency rules.
1999-11-23 <tytso@valinux.com>
* e2fsck.8.in: Update language about where to find a backup
superblock.
1999-11-19 <tytso@valinux.com>
* pass1.c (process_inodes): Add shortcut handling; if
process_inodes_count is zero, return right away, to avoid
calling qsort with a non-positive count.
* message.c (safe_print): Fix to properly display ^A, ^B, etc. and
to print Delete as ^?
* Makefile.in (distclean): Remove TAGS and Makefile.in.old from
the source directory.
1999-11-10 <tytso@valinux.com>
* Release of E2fsprogs 1.18
1999-11-10 <tytso@valinux.com>
* problem.c (fix_problem): Support a new flag, PR_PREEN_NO which
means the answer is assumed to be no in preen mode. This
is now used in the PR_1_SET_IMMUTABLE code, so that in
preen mode we ignore these inodes and just print a warning
message.
1999-11-09 <tytso@valinux.com>
* pass1.c (e2fsck_pass1): If the filesystem does not support
imagic inodes, if an inode has the imagic flag set, offer
to clear the imagic flag. If a valid device/fifo/socket
has the immutable flag set, call the new helper function
check_immutable() to offerto clear the immutable flag.
* pass2.c (check_filetype): Use the new ext2_file_type() helper
function instead of calculating the file_type information
manually.
* pass3.c (e2fsck_reconnect_file): When adding a link to
lost+found, calculate the filetype information so that
ext2fs_link() can use the information if applicable.
(get_lost_and_found): Create the /lost+found directory
with the correct filetype information if applicable.
* util.c (ext2_file_type), e2fsck.h: New function which returns
the directory entry file type information given the
inode's mode bits.
* problem.c, problem.h: Added new problem codes PR_1_SET_IMAGIC
and PR_1_SET_IMMUTABLE.
1999-11-07 <tytso@valinux.com>
* pass4.c (e2fsck_pass4): Clear inode_imagic_map after freeing it,
to prevent it from getting freed twice.
1999-11-06 <tytso@valinux.com>
* unix.c (main): Close the filesystem before freeing the context,
so that in the event of a free()-related segmentation
violation, the filesystem is properly closed and written
out.
1999-10-27 <tytso@valinux.com>
* e2fsck.c (e2fsck_reset_context): When freeing
ctx->inode_reg_map, we weren't zero'ing
ctx->inode_reg_map, which could cause a segfault later on
in the e2fsck run.
1999-10-26 <tytso@valinux.com>
* problem.h (PR_2_SPLIT_DOT): Fix excess zero in problem code (now
matches the standard convention).
1999-10-26 <tytso@valinux.com>
* Release of E2fsprogs 1.17
1999-10-26 <tytso@valinux.com>
* message.c (safe_print): Make safe_print take an char instead of
an unsigned char to fix gcc warnings.
1999-10-25 <tytso@valinux.com>
* util.c: For NT portability, don't redefine getchar(), since
stdio defines that. Instead we introduce a new
abstract macro read_a_char() which is #defined to the
right function as necessary.
* problem.c, problem.h (PR_2_NULL_NAME): Add new problem code.
* pass2.c (check_dir_block): Require that the length of the
directory entry be at least 12 bytes. Check to see if the
filename is zero-length, and flag that as an error.
1999-10-22 <tytso@valinux.com>
* Release of E2fsprogs 1.16
1999-10-22 <tytso@valinux.com>
* pass2.c (check_filetype): If the filetype filesystem feature is
not set, and a directory entry has a dirent feature, offer
to clear it (since 2.0 kernels will do complain will
interpret it as a very large name length field).
* problem.c (PR_2_CLEAR_FILETYPE): Add new problem code.
1999-10-21 <tytso@valinux.com>
* e2fsck.8.in: Update man page to use a more standard format (bold
option flags and italicized variables), as suggested by
Andreas Dilger (adilger@enel.ucalgary.ca)
* pass4.c (e2fsck_pass4): If an inode is set in the
inode_imagic_map bitmap, don't check to see if it is
disconnected from the inode tree (because it almost
certainly will be). Free inode_imagic_map at the end of
pass 4.
* pass2.c (check_dir_block, check_filetype): If the FILETYPE
feature is set, check the directory entry's filetype
information field, and fix/set it if necessary.
(e2fsck_pass2): Free the inode_reg_map bitmap at the end
of pass 2.
* pass1.c (e2fsck_pass1, alloc_imagic_map): Allocate and fill in
information for inode_reg_map and inode_imagic_map, which
indicates which inodes are regular files and AFS inodes,
respectively.
Since only the master superblock is written during a
restart, force that superblock to be used after a restart;
otherwise changes to the block group descriptors end up
getting ignored.
* problem.c, problemP.h: If e2fsck is run -n, make def_yn variable
be 0 for "no". Add support for a new flag, PR_NO_NOMSG,
which supresses 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 problem codes.
* message.c (expand_dirent_expression): Add support for %dt which
prints the dirent type information.
* e2fsck.c (e2fsck_reset_context): Free new bitmaps (inode_reg_map
and inode_imagic_map).
* e2fsck.h (e2fsck_t): Add new inode_reg_map and inode_magic_map
to the context structure.
1999-09-24 <tytso@valinux.com>
* unix.c (PRS), util.c (ask_yn): Add #ifdef's to make
e2fsprogs easier to port to non-Unix platforms.
1999-09-07 <tytso@valinux.com>
* pass3.c (adjust_inode_count): Fix bug where we didn't keep the
internal and external inode counts in sync when we
decremented an inode whose link count was already zero.
Now we skip incrementing or decrementing both link counts
if we would cause an overflow condition.
(expand_dir, expand_dir_proc): Change where we update the
inode block count and size files so that the block count
field is updated correctly when we create an indirect block.
1999-08-05 <tytso@valinux.com>
* super.c (check_super_block): Check to see whether the
inodes_per_group value in the superblock is insanely too
high.
1999-08-02 <tytso@valinux.com>
* pass1b.c (clone_file_block): Don't clear the dup_map flag if
the block also shares data with the fs metadata when
the count drops to 1, since the block should still be
cloned, as fs metadata isn't included in the count.
1999-07-18 Theodore Ts'o <tytso@valinux.com>
* Release of E2fsprogs 1.15
1999-07-19 <tytso@valinux.com>
* unix.c (usage): Add minimalist emergency help to the usage
message.
1999-07-18 <tytso@valinux.com>
* unix.c: Add support for calculating a progress bar if the -C0
option is given. The function e2fsck_clear_progbar()
clears the progress bar and must be called before any
message is issued. SIGUSR1 will enable the progress bar,
and SIGUSR2 will disable the progress bar. This is used
by fsck to handle parallel filesystem checks. Also, set
the device_name from the filesystem label if it is
available.
* e2fsck.h: Add new flags E2F_FLAG_PROG_BAR and
E2F_FLAG_PROG_SUPRESS. Add new field in the e2fsck
structure which contains the last tenth of a percent
printed for the user.
* message.c (print_e2fsck_message): Add call to
e2fsck_clear_progbar().
* pass1.c (e2fsck_pass1):
* pass2.c (e2fsck_pass2):
* pass3.c (e2fsck_pass3):
* pass4.c (e2fsck_pass4):
* pass5.c (e2fsck_pass5): Add call to e2fsck_clear_progbar when
printing the resource tracking information.
* pass5.c (check_block_bitmaps, check_inode_bitmaps): If there is
an error in the bitmaps, suppress printing the progress
bar using the suppression flag for the remainder of the
check, in order to clean up the display.
1999-06-30 <tytso@valinux.com>
* unix.c (check_mount): Clean up the abort message displayed when
the filesystem is mounted and either stdout or stdin isn't
a tty.

* pass1.c (pass1_get_blocks, pass1_read_inode, pass1_write_inode,
pass1_check_directory, e2fsck_use_inode_shortcuts): Make
pass1_* be private static functions, and create new
function e2fsck_use_inode_shortcuts which sets and clears
the inode shortcut functions in the fs structure.
* e2fsck.h:
* pass2.c (e2fsck_process_bad_inode): Make process_bad_inode() an
exported function.
* pass4.c (e2fsck_pass4): Call e2fsck_process_bad_inode to check
if a disconnected inode has any problems before
connecting it to /lost+found. Bug and suggested fix by
Pavel Machek <pavel@bug.ucw.cz>
1999-06-21 <tytso@valinux.com>
* unix.c (main): Add missing space in the disk write-protected
message.
1999-05-22 <tytso@rsts-11.mit.edu>
* problem.c, problem.h (PR_0_INODE_COUNT_WRONG): Add new problem
code.
* super.c (check_super_block): Add check to make sure the total
number of inodes is sane, since this can be calculated
from the number of groups times the number of inodes per
group. Offer to correct it if it is incorrect.
1999-03-19 <tytso@rsts-11.mit.edu>
* pass5.c (check_block_end): Fix fencepost condition where when
clearing the block padding we were missing the last position
in the bitmap.
1999-05-17 <tytso@rsts-11.mit.edu>

* util.c (print_resource_track): Use mallinfo if present to get
more accurate malloc statistics.
* pass3.c (get_lost_and_found): Check to see if lost+found is a
plain file; if so, offer to unlink it.

1999-03-09 Theodore Ts'o <tytso@rsts-11.mit.edu>
* problem.c: Fix problem message for PR_1_BAD_GROUP_DESCRIPTORS so
that the block group number is printed. Add new prompt,
PROMPT_UNLINK.
1999-01-09 Theodore Ts'o <tytso@rsts-11.mit.edu>
* Release of E2fsprogs 1.14
1999-01-09 Theodore Ts'o <tytso@rsts-11.mit.edu>
* message.c (safe_print): New function which prints strings,
converting non-printable characters using the '^' and
M-notation. This function is now used to print directory
name entries and pathnames.
Mon Jan 4 02:28:59 1999 Theodore Y. Ts'o <tytso@mit.edu>
* unix.c (main): Reset the context before calling ext2fs_close(),
to avoid referencing already freed memory.
1998-12-15 Theodore Ts'o <tytso@rsts-11.mit.edu>
* Release of E2fsprogs 1.13
1998-12-03 Theodore Ts'o <tytso@rsts-11.mit.edu>
* Makefile.in: Updated dependencies.
1998-11-27 Theodore Ts'o <tytso@rsts-11.mit.edu>
* pass3.c (get_lost_and_found): If the filesystem is not opened
read-only, then force /lost+found to be created if it is
not present.
* problem.c: Allow PR_3_NO_LF_DIR to be handled during a preen
operation.
1998-10-28 Theodore Ts'o <tytso@rsts-11.mit.edu>
* 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.
1998-10-09 Theodore Ts'o <tytso@rsts-11.mit.edu>
* 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.
1998-09-02 Theodore Ts'o <tytso@rsts-11.mit.edu>
* problem.c: Add PR_3_NO_DIRINFO error code.
* super.c (check_super_value): Rename min and max to min_val and
max_val to avoid possible cpp macro conflicts.
* pass4.c (e2fsck_pass4): Rename max to maxgroup, to avoid
possible cpp macro conflicts.
* pass3.c (e2fsck_pass3): Rename max to maxdirs, to avoid possible
cpp macro conflicts.
(check_directory): Fix logic to avoid possible core dump
in the case of ext2fs_get_dir_info returning NULL. (By
the time we get here, it should never happen, but...).
Also simply/streamline the control flow of the function.
1998-08-17 Theodore Ts'o <tytso@rsts-11.mit.edu>
* unix.c (check_if_skip): Move the "not cleanly mounted" check
ahead of the maximal mount and too long since checked tests.
(reserve_stdio_fds): Make sure 0,1,2 file descriptors are
open, so that we don't open the filesystem using the same
file descriptor as stdout or stderr.
1998-08-01 Theodore Ts'o <tytso@rsts-11.mit.edu>
* pass2.c (e2fsck_pass2): Fix the progress accounting so that we
get to 100%.
* pass3.c (e2fsck_pass3): Change progress accounting to be
consistent with the other e2fsck passes.
* e2fsck.c (e2fsck_run): At the end of each pass, call the
progress function with the pass number set to zero.
* unix.c (e2fsck_update_progress): If the pass number is zero,
ignore the call, since that indicates that we just want to
deallocate any progress structures.
1998-07-09 Theodore Ts'o <tytso@rsts-11.mit.edu>
* Release of E2fsprogs 1.12
1998-07-09 Theodore Ts'o <tytso@rsts-11.mit.edu>
* unix.c (main): Fix typo in checking the incompat feature set; it
should be checked against EXT2_LIB_FEATURE_INCOMPAT_SUPP.
1998-07-07 Theodore Ts'o <tytso@rsts-11.mit.edu>
* badblocks.c (test_disk): Don't clear the existing bad blocks
list when using e2fsck -c, since it may cause blocks with
marginal errors to be dropped from the bad blocks list.
Mon Jul 6 10:32:11 1998 Theodre Ts'o <tytso@lurch.mit.edu>
* pass1.c (e2fsck_pass1): Use ext2fs_sb structure for
compatibility with older kernels.
1998-06-25 Theodore Ts'o <tytso@rsts-11.mit.edu>
* unix.c (e2fsck_update_progress): Remove unused variables.
1998-06-10 Theodore Ts'o <tytso@rsts-11.mit.edu>
* pass1.c, problem.h: Change blkcnt_t to be e2_blkcnt_t to avoid
collision with LFS API.
* pass1.c (e2fsck_pass1): Fix bug so that ext2_max_sizes is
properly initialized.
(e2fsck_pass1): Don't allow the the boot loader inode to
be a directory (clear the inode mode field if so).
1998-05-07 Theodore Ts'o <tytso@rsts-11.mit.edu>
* unix.c (PRS): Added new option -C, which causes e2fsck to print
progress updates so that callers can keep track of the
completion progress of e2fsck. Designed for use by
progress, except for -C 0, which prints a spinning report
which may be useful for some users.
* pass5.c (e2fsck_pass5): Use a finer-grained progress reporting
scheme (useful for larger filesystems).
* e2fsck.h: Add progress_fd and progress_pos, for use by the Unix
progress reporting functions.
1998-04-28 Theodore Ts'o <tytso@rsts-11.mit.edu>
* pass1.c (process_inode_cmp): Use EXT2_QSORT_TYPE to define the
appropriate return type for comparison functions for qsort.
* e2fsck.h: Add #ifdef protection for unistd.h
* super.c: Remove header files already included by e2fsck.h
1998-04-26 Theodore Ts'o <tytso@rsts-11.mit.edu>
* dirinfo.c (e2fsck_add_dir_info): Update function to pass the old
size of the memory to be resized to ext2fs_resize_mem().
1998-03-30 Theodore Ts'o <tytso@rsts-11.mit.edu>
* Makefile.in: Change to use new installation directory variables
convention. Fix uninstall rules to take $(DESTDIR) into
account. Remove cat8dir from the installdirs target,
since modern man package don't necessarily put the cat
directory in /usr/man/cat?.
1998-03-29 Theodore Ts'o <tytso@rsts-11.mit.edu>
* super.c, e2fsck.h: Always declare e2fsck_get_device_size() as an
extern in e2fsck.h to prevent -Wall warnings.
* pass4.c (e2fsck_pass4): Remove unused variable 'j'.
1998-03-28 Theodore Ts'o <tytso@rsts-11.mit.edu>
* super.c (check_super_block): Fix broken superblock sanity check
when calculating blocks_per_group if s_log_frag_size !=
s_log_block_size. Since we don't support fragments, this
isn't a bug deal, but it's good to get it fixed.
1998-03-23 Theodore Ts'o <tytso@rsts-11.mit.edu>
* unix.c: Fix bug in check of feature set, to make sure we can
really fix this filesystem.
* problem.h: Make blkcount type to be of type blkcnt_t. Make the
num field be a 64 bit type. Add the problem code
PR_1_FEATURE_LARGE_FILES
* problem.c: Add table entry for the problem code
PR_1_FEATURE_LARGE_FILES.
* pass1.c (e2fsck_pass1): A non-zero i_dir_acl field is only
a problem for directory inodes. (Since it is also
i_size_high now.) If there are no large_files, then
clear the LARGE_FLAG feature flag. If there are
large_files, but the LARGE_FLAG feature flag is not set,
complain and offer to fix it.
(check_blocks): Add support to deal with non-directory
inodes that have i_size_high set (i.e., large_files).
Don't give an error if a directory has preallocated
blocks, to support the DIR_PREALLOC feature.
(process_block, process_bad_block): The blockcnt variable
is a type of blkcnt_t, for conversion to the new
block_iterate2.
* pass2.c (process_bad_inode): A non-zero i_dir_acl field is only
a problem for directory inodes. (Since it is also
i_size_high now.)
* message.c (expand_inode_expression): Print a 64-bits of the
inode size for non-directory inodes. (Directory inodes
can only use a 32-bit directory acl size, since
i_size_high is shared with i_dir_acl.) Add sanity check
so that trying to print out the directory acl on a
non-directory inode will print zero.
(expand_percent_expression): %B and %N, which print
pctx->blkcount and pctx->num, can now be 64 bit
variables. Print them using the "%lld" format if
EXT2_NO_64_TYPE is not defined.
* e2fsck.h: Add the large_flagsfield to the e2fsck context.
* e2fsck.c (e2fsck_reset_context): Clear the large_flags
field.
Sun Mar 8 23:08:08 1998 Theodore Ts'o <tytso@rsts-11.mit.edu>
* pass3.c (fix_dotdot_proc):
* pass2.c (check_dot, check_dotdot, check_name, check_dir_block):
* message.c (expand_dirent_expression): Mask off the high eight
bits of the directory entry's name_len field, so that it
can be used for other purposes.
Fri Feb 27 00:01:39 1998 Theodore Ts'o <tytso@rsts-11.mit.edu>
* e2fsck.c (e2fsck_run): Since E2F_FLAG_SIGNAL_MASK doesn't
include EXT2_FLAG_RESTART anymore, we need to adjust this
routine so that it *does* return in the case of it seeing
EXT2_FLAG_RESTART.
* pass1.c (e2fsck_pass1): ext2_get_next_inode() may call the group
done callback function, which may set context abort
flags. So we need to test the context abort flags after
we call ext2_get_next_inode().
(process_inodes): If we abort due out of process_inodes,
do a clean exit by breaking out of the for loop instead of
just returning.
* e2fsck.h (E2F_FLAG_SIGNAL_MASK): EXT2_FLAG_RESTART shouldn't be
considered a SIGNAL mask (i.e., requiring an immediate
abort of processing to restart). FLAG_RESTART just means
that we want to restart once pass 1 is complete.
Tue Feb 24 15:19:40 1998 Theodore Ts'o <tytso@rsts-11.mit.edu>
* Change the progress function to return an integer; if returns 1,
then the progress function is expected to have set the
e2fsck context flag signalling a user abort, and the
caller should also initiate a user abort.
Tue Feb 17 19:03:44 1998 Theodore Ts'o <tytso@rsts-11.mit.edu>
* pass5.c (check_block_bitmaps, check_inode_bitmaps): Don't call
end_problem_latch() unless there was actually a problem
latched. Simplifies semantics of the latch processing.
Mon Feb 16 17:31:44 1998 Theodore Ts'o <tytso@rsts-11.mit.edu>
* e2fsck.h: Add new field, priv_data to the e2fsck context
structure. It should be used by callers of the e2fsck
functions only, and not by anything in e2fsck itself.
Mon Feb 7 17:31:04 1998 Theodore Ts'o <tytso@rsts-11.mit.edu>
* super.c: Instead of call ext2fs_get_device_size(), define and call
e2fsck_get_device_size(). (This function may be stubbed
out in special versions of e2fsck.)
* pass3.c, pass4.c: Remove extra calls to the progress function
that weren't needed.
* mke2fs.8.in: Update man page to note that the format of the bad
block file is the same as the one generated by badblocks.
Sun Feb 1 07:57:14 1998 Theodore Ts'o <tytso@rsts-11.mit.edu>
* dirinfo.c, e2fsck.c: Don't include com_err.h; it isn't needed.
* e2fsck.h: Include <time.h> since it is needed
* super.c: If EXT2_SKIP_UUID is defined, then skip the UUID
processing.
Tue Jan 20 15:37:01 1998 Theodore Ts'o <tytso@rsts-11.mit.edu>
* unix.c (main): In the case where the filesystem revision is too
high, print the message about the superblock possibly
being corrupt.
* e2fsck.8.in: Add expanded comments about how the -b option
works.
Sat Jan 17 13:02:16 1998 Theodore Ts'o <tytso@rsts-11.mit.edu>
* e2fsck.h: If EXT2_FLAT_INCLUDES is defined, then assume all of
the ext2-specific header files are in a flat directory.
* dirinfo.c, ehandler.c, pass1.c, pass1b.c, pass2.c, pass5.c,
super.c, swapfs.c, unix.c: Explicitly cast all assignments
from void * to be compatible with C++.
Tue Jan 6 11:30:24 1998 Theodore Ts'o <tytso@rsts-11.mit.edu>
* unix.c (sync_disk): Remove sync_disk and calls to that function,
since ext2fs_close() now takes care of this.
Mon Dec 29 14:45:42 1997 Theodore Ts'o <tytso@rsts-11.mit.edu>
* pass1.c, pass1b.c, pass2.c, pass3.c, swapfs, badblocks.c,
ehandler.c, unix.c: Change use of private to be priv_data,
to avoid C++ reserved name clash.
Fri Nov 28 09:30:26 1997 Theodore Ts'o <tytso@rsts-11.mit.edu>
* dirinfo.c (e2fsck_add_dir_info): Use ext2fs_get_num_dirs instead
of e2fsck_get_num_dirs, which has been removed.
Tue Nov 25 15:54:35 1997 Theodore Ts'o <tytso@rsts-11.mit.edu>
* Makefile.in (PROGS): Remove @EXTRA_PROGS@, since we don't want
to compile and install flushb.
Mon Nov 24 06:48:00 1997 Theodore Ts'o <tytso@rsts-11.mit.edu>
* pass1.c (e2fsck_pass1_check_device_inode): For now, only check
to make sure the extra i_blocks in a device are cleared if
the immutable flag is set.
* util.c (print_resource_track): Fix typo which caused the
time/resource tracking to print "Pass 1 :" instead of
"Pass 1: ".
Thu Nov 20 16:02:23 1997 Theodore Ts'o <tytso@rsts-11.mit.edu>
* pass3.c (expand_directory): Fix bug which could cause core dump
when expanding the directory, and the bitmaps hadn't yet
been read in. Also, only use ext2fs_write_dir_block when
writing a directory block, not when writing out a fresh
indirect block.
Wed Nov 19 16:15:44 1997 Theodore Ts'o <tytso@rsts-11.mit.edu>
* pass1.c (process_bad_block): Fix bug where first_block wasn't
getting incremented, which caused user to get a
"Programming error?" warning if there was a bad block in a
non-primary superblock/group_descriptor. Also fixed
another bug so that ext2fs_bg_has_super() is consulted, to
avoid problems when using a filesystem with the
sparse_groups option set and there are bad blocks at the
beginning of a group which doesn't have a superblock.
Thu Nov 6 16:10:20 1997 Theodore Ts'o <tytso@rsts-11.mit.edu>
* pass1.c, pass2.c, pass3.c, pass4.c, pass5.c: Add calls to the
progress indicator function.

get_device_size returns EXT2_EXT_UNIMPLEMENTED.
* iscan.c (main): Don't use fatal_error() anymore.
* pass1b.c, swapfs.c, badblocks.c: Set E2F_FLAG_ABORT instead of
calling fatal_error(0).
* problem.c, pass3.c (PR_3_ROOT_NOT_DIR_ABORT,
PR_3_NO_ROOT_INODE_ABORT): New problem codes.
* problem.c, pass2.c (PR_2_SPLIT_DOT): New problem code.
* problem.c, pass1.c (PR_1_SUPPRESS_MESSAGES): New problem code.
* problemP.h: New file which separates out the private fix_problem
data structures.
* util.c, dirinfo.c, pass1.c, pass1b.c, pass2.c, pass5.c, super.c,
swapfs.c util.c: allocate_memory() now takes a e2fsck
context as its first argument, and rename it to be
e2fsck_allocate_memory().
Mon Nov 3 14:35:29 1997 Theodore Ts'o <tytso@rsts-11.mit.edu>
* unix.c (main): Add a special case check for the error code EROFS
and display an appropriate error message for this case.
* [lots of files]: Change ext2fs_read_inode, ext2fs_write_inode
to take the e2fsck context as their first argument.
Change dir_info.c routines to take an e2fsck_context,
renamed them to start with e2fsck_ to avoid namespace
issues, and changed them to store the directory
information inside the e2fsck context.
Added e2fsck_run() which calls all of the e2fsck passes in
the correct order, and which handles the return of abort
codes. Added abort processing, both via setjmp/longjmp
and via flags in the e2fsck context. Use a flag in the
e2fsck context instead of the restart_e2fsck global
variable. Change uses of free and malloc to
ext2fs_free_mem and ext2fs_get_mem.
Fri Oct 31 01:12:43 1997 Theodore Ts'o <tytso@rsts-11.mit.edu>
* pass1.c, pass3.c: Rename new error codes to _ET_ in them for
consistency.
Sat Oct 25 00:10:58 1997 Theodore Ts'o <tytso@rsts-11.mit.edu>
* pass3.c (get_lost_and_found): Check error return of
EXT2_FILE_NOT_FOUND instead of ENOTDIR
* pass1.c (pass1_check_directory): Return EXT2_NO_DIRECTORY
instead of ENOTDIR
Fri Oct 24 00:12:39 1997 Theodore Ts'o <tytso@rsts-11.mit.edu>
* unix.c (PRS): Make the variable which getopt returns into be
an int, so that it won't lose on platforms where char is
unsigned.
* pass1b.c (clone_file): Fix bug in error reporting in the case
where cs.errcode is non-zero.
Sun Oct 19 21:12:11 1997 Theodore Ts'o <tytso@rsts-11.mit.edu>
* pass*.c, super.c, unix.c, util.c, e2fsck.h: Place #ifdef
RESOURCE_TRACK around code which uses init_resource_track
and print_resource_track. (Not all systems have timeval)

Fri Oct 3 13:40:03 1997 Theodore Ts'o <tytso@rsts-11.mit.edu>
* 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.
Sat Sep 6 17:13:28 1997 Theodore Ts'o <tytso@rsts-11.mit.edu>
* pass2.c (check_dir_block): Check for duplicate '.' and '..'
entries.

PR_2_DUP_DOT_DOT.
Tue Sep 2 09:04:51 1997 Theodore Ts'o <tytso@rsts-11.mit.edu>
* 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.
Mon Aug 25 10:23:13 1997 Theodore Ts'o <tytso@rsts-11.mit.edu>
* 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

* pass1.c (pass1, check_device_inode), pass2.c
(process_bad_inode): Use a more stringent test for a valid
device.

Thu Jun 12 00:25:31 1997 Theodore Ts'o <tytso@rsts-11.mit.edu>
* pass1.c (mark_table_blocks): Mark the superblock and group
descriptor blocks first, so that any conflicts between
these and the bitmap or inode table blocks is noticed.
* problem.c: Fix message printed out when a block or inode bitmap
conflicts with other fs data, has the correct group number
in it.
Tue Jun 10 12:07:37 1997 Theodore Ts'o <tytso@rsts-11.mit.edu>
* pass2.c (pass2): Check the error return from ext2fs_dblist_iterate.
Thu May 8 22:45:27 1997 Theodore Ts'o <tytso@rsts-11.mit.edu>
* e2fsck.8.in: Fix minor typos and grammer oops found by Bill
Hawes (whawes@star.net).
* badblocks.c (read_bad_blocks_file): Pass the blocksize to the
bad blocks command so that all of the filesystem gets
tested in the case where the blocksize 2048 or 4096.
Thu Apr 24 12:16:42 1997 Theodre Ts'o <tytso@localhost.mit.edu>

Thu Apr 10 13:51:16 1997 Theodore Ts'o <tytso@rsts-11.mit.edu>
* pass1b.c (clone_file_block): If we clone a directory, we need to
update the dblist entry so that we check (and correct) the
right directory block.
Sun Apr 6 09:13:12 1997 Theodore Ts'o <tytso@rsts-11.mit.edu>
* pass1.c (process_block): Don't clear blocks references to
filesystem metadata; let pass 1B handle this case.
* problem.c, problem.h: Add new problem, PR_1B_SHARE_METADATA.
* pass1b.c (pass1d): Deal with a block which is shared with
filesystem metadata.
* e2fsck.h: Make block_illegal_map be a global variable
Sat Apr 5 11:51:58 1997 Theodore Ts'o <tytso@rsts-11.mit.edu>
* e2fsck.c, pass1.c (mark_table_blocks): Support the sparse_super
feature.
(get_backup_sb): New function which attempts to obtain the
correct backup superblock (if possible).
Fri Apr 4 10:46:26 1997 Theodore Ts'o <tytso@rsts-11.mit.edu>
* e2fsck.c (main): Check the version of the library, and warn if
the library is out of date; this happens generally due to
users who manually install e2fsprogs.
* pass1.c (pass1_get_blocks): If the passed in inode number for
get_blocks isn't what we're expecting pass back
EXT2_ET_CALLBACK_NOT_HANDLED.
Wed Mar 12 13:32:05 1997 Theodore Y. Ts'o <tytso@mit.edu>
* Release of E2fsprogs version 1.07
Tue Mar 11 10:31:47 1997 Theodore Ts'o <tytso@rsts-11.mit.edu>
* icount.c: New file which implements an inode count abstraction.
This significantly reduces amount of memory needed to
check really large filesystems.
* pass1.c, pass2.c, pass3.c, pass4.c: Modified to use the icount
abstraction.
Fri Mar 7 08:28:55 1997 Theodore Ts'o <tytso@rsts-11.mit.edu>
* dirinfo.c (dir_info_iter): New function which allows iteration
over the directories in the dir_info map.
* pass3.c (pass3, check_directory): Speed up pass 3 by iterating
over all directories in the dir_info structure, instead of
iterating all inodes looking for directories, and then
looking up the directories using get_dir_info().
Sat Feb 1 11:33:43 1997 Theodore Ts'o <tytso@rsts-11.mit.edu>
* pass1.c (pass1, process_block):
* pass2.c (pass2): Use the ext2_dblist abstraction instead of
manual code to manage the directory block list information.
* pass1.c (check_blocks), pass1b.c (pass1b), pass2.c
(deallocate_inode): Call the ext2 library routine
ext2_inode_has_valid_blocks() instead of
inode_has_valid_blocks().
* swapfs.c (swap_inodes): Add check so that we don't try to call
swap_inode_blocks unless the inode has valid blocks.
(Otherwise a long fast symlink might cause
swap_inode_blocks to erroneously get called.)
Wed Jan 22 14:42:53 1997 Theodore Ts'o <tytso@rsts-11.mit.edu>
* problem.c, problem.h: Added entries for PR_2_DOT_NULL_TERM and
PR_2_DOT_DOT_NULL_TERM.
* pass2.c (check_dot, check_dot_dot): Make sure the new . and
.. entries are null-terminated, since the 2.0 kernel
requires this (for no good reason).
Mon Jan 20 20:05:11 1997 Theodore Ts'o <tytso@rsts-11.mit.edu>
* pass1.c (pass1): Set the EXT2_SF_SKIP_MISSING_ITABLE flag so
that we can recover from missing inode tables.
* dirinfo.c (get_dir_info): If there are no directories in the
dir_info abstraction, don't core dump (because dir_info is
NULL).
* e2fsck.c (main): Don't try using the backup superblocks if there
aren't any.
(check_super_block): If there are illegal inode table or
bitmaps, set the filesystem as being in error.
Wed Jan 15 11:32:01 1997 Theodore Ts'o <tytso@rsts-11.mit.edu>
* pass2.c (check_dir_block): Added check to make sure that rec_len
is a a multiple of 4 (so that the directory entries are
4-byte aligned).
Sat Dec 28 12:16:32 1996 Theodore Ts'o <tytso@rsts-11.mit.edu>
* Makefile.in (uninstall): Uninstall all programs in the PROGS
line.
(PROGS): Don't build and install the extend program by
default.
Sat Dec 7 16:41:02 1996 Theodore Ts'o <tytso@rsts-11.mit.edu>
* pass1.c (process_inodes): Make sure the stashed_ino variable is
saved and restored as well.
(pass1): For fast sym links, skip the check_blocks
processing step altogether.
Mon Dec 2 09:28:24 1996 Theodore Ts'o <tytso@rsts-11.mit.edu>
* problem.c, message.c: New files, to completely refurbish how
filesystem problems are reported to the user. The
diagnostic messages are now encoded out in an easily
customizable, extensible format. The messages printed out
in preen mode are all on one line, and contain the device
name.
Fri Nov 29 20:26:08 1996 Theodore Ts'o <tytso@rsts-11.mit.edu>
* swapfs.c (swap_inodes): When swapping a filesystem, ignore
deleted files.
* pass1.c (pass1): Ignore missing inode table errors during the
scan, and just skip past those inodes.
* pass3.c (check_root): Remove root_ino argument, and assume that
the root inode must be EXT2_ROOT_INO. Move responsibility
of setting the parent of the root inode in the directory
inode structure to pass2().
* pass2.c (check_dir_block): Don't allow links to the root
directory.
* dirinfo.c (add_dir_info): Remove last argument to add_dir_info,
since the inode is no longer used.
Tue Oct 15 00:06:49 1996 Theodore Ts'o <tytso@rsts-11.mit.edu>
* e2fsck.c (main): If the superblock magic number is wrong, or the
block group fails a sanity check, then automatically
restart trying to use the backup superblocks.
* pass1.c (mark_table_blocks): Make the inode tables ahead of
everything else; in the case where a bitmap block overlays
the inode table, the inode table should take precedence.
* pass2.c (maybe_clear_entry): Make the deleted/unused error
message fit on one line, since the error can happen during
a preen pass. (We eventually need to revamp the whole
e2fsck error reporting and prompting system, but that's a
job for another day.)
Mon Oct 14 22:29:49 1996 Theodore Ts'o <tytso@rsts-11.mit.edu>
* e2fsck.c (main): Read in the list badblocks into fs->badblocks
for the benefit of the inode scan functions.
* pass1.c (pass1): If ext2fs_get_next_inode() returns an error
indicating that an inode is in a bad block, mark that
inode as being used, as well as in the inode "bb" map.
* pass2.c (maybe_clear_entry): New function which generalizes the
error cases when a directory entry needs to be cleared.
(check_dir_block): If an inode is in the "bb" map, offer
to clear the directory entry, since the inode is in a bad
block.
* pass4.c (pass4): If an inode is marked as used, but is is marked
in the "bb" map, don't process it as a disconnected inode.
Tue Oct 8 02:02:03 1996 Theodore Ts'o <tytso@rsts-11.mit.edu>
* Release of E2fsprogs version 1.06
Mon Oct 7 00:45:30 1996 Theodore Ts'o <tytso@rsts-11.mit.edu>
* e2fsck.c (main): Print out the version number of the shared
library when using the -V option.
* swapfs.c (swap_filesys): Change EXT2_SWAP to EXT2_FLAG_SWAP for
consistency's sake.
* e2fsck.c (main): By setting EXT2_FLAG_MASTER_SB_ONLY, only write
out the backup superblocks when we know we have a valid
filesystem.
Tue Oct 1 22:00:29 1996 Theodore Ts'o <tytso@rsts-11.mit.edu>
* util.c (preenhalt): Make it explicit on preenhalt that running
e2fsck manually means without the -a or -p flag.
Fri Sep 27 14:41:08 1996 Theodore Ts'o <tytso@rsts-11.mit.edu>
* pass1.c (pass1): Add support for the EXT2_BOOT_LOADER inode.
(Linux/FT actually sets the mode bits, so we have to
handle it specially.)
* e2fsck.c (check_if_skip): Print a message if the filesystem is
just dirty, so that the user knows that it's about to be
checked (since this will take a while).
Mon Sep 16 17:00:01 1996 Theodore Ts'o <tytso@rsts-11.mit.edu>
* pass4.c: If a disconnected inode is zero-length, prompt to
delete it instead of connecting it to lost+found.
Thu Sep 12 15:23:07 1996 Theodore Ts'o <tytso@rsts-11.mit.edu>
* Release of E2fsprogs version 1.05
Fri Aug 30 20:24:30 1996 Theodore Ts'o <tytso@rsts-11.mit.edu>
* pass4.c (pass4): If the user refuses to connect an unattached
inode to lost+found, don't try to set i_links_count. This
is bad, since if the user says yes, the inode will be
marked as unused, which is not necessarily the right
thing, especially since the rest of the cleanup doesn't
happen here.
* pass2.c (deallocate_inode): Set inode_link_info[ino] when
dellocating an inode. (Not strictly necessary, but...)
* pass4.c (pass4): Add "bonehead" explanation to the "programming
error" message.
Tue Aug 27 11:26:32 1996 Theodore Ts'o <tytso@rsts-11.mit.edu>
* e2fsck.c (PRS,main): Added new options -s and -S. -s will
byte-swap the filesystem so that it is normalized. -S
will byte-swap the filesystem regardless of its current
byte-order.
* swapfs.c: New file, which will byte-swap a filesystem.
Tue Aug 20 09:41:37 1996 Theodore Ts'o <tytso@rsts-11.mit.edu>
* pass1.c (pass1): Change handling on files with non-zero dtime
and non-zero i_link_count; before we treated them as
deleted file per botched ext2 0.3c kernel behavior. We
now clear dtime instead.
Mon Aug 19 23:33:57 1996 Theodore Ts'o <tytso@rsts-11.mit.edu>
* e2fsck.c (main): If e2fsck sets the clean bit, even if
nothing else is changed, make sure FSCK_NONDESTRUCT is
set (since after all having the filesystem set to
invalid is an error. :-)
Fri Aug 9 10:25:13 1996 Theodore Ts'o <tytso@rsts-11.mit.edu>
* pass1.c (process_block): Make sure that meta data doesn't get
accidentally set in the dir_blocks array (which could
happen in some error condtions).
* pass1.c (pass1):
* pass2.c (process_bad_inode): Check for fragments in a
OS-independent fashion.
Thu Aug 8 15:20:54 1996 Theodore Ts'o <tytso@rsts-11.mit.edu>
* e2fsck.c (check_if_skip): Close the filesystem when skipping the
cleanup for the filesystem.
Mon Jul 22 22:03:28 1996 Theodore Ts'o <tytso@rsts-11.mit.edu>
* e2fsck.c: Improve corrupt_msg, so that it's less confusing.
Thu May 16 11:12:30 1996 Theodore Ts'o <tytso@rsts-11.mit.edu>
* Release of E2fsprogs version 1.04
Wed May 15 21:41:29 1996 Theodore Ts'o <tytso@rsts-11.mit.edu>
* e2fsck.c (relocate_hint): Issue a hint that the user may wish to
try "e2fsck -b 8193" before allowing e2fsck to relocate
inode table blocks.
* Makefile.in (e2fsck): Build e2fsck statically or dynamically
depending on the option to configure. Added targets for
e2fsck.static and e2fsck.shared for people who want to
build a static or shared variant manually.
Wed Mar 27 00:33:40 1996 <tytso@rsts-11.mit.edu>
* Release of E2fsprogs version 1.03
Tue Mar 26 12:03:42 1996 <tytso@rsts-11.mit.edu>
* e2fsck.c (show_stats): Don't use floating point to display
percentage of non-contiguous files, as different libc
handle result truncation differently, and this causes the
test suite to bomb out depending on which libc you are
using.
* util.c (allocate_memory): Fix error message to omit extraneous
%%s.
Tue Mar 5 03:50:40 1996 <tytso@rsts-11.mit.edu>
* pass4.c (pass4):
* pass2.c (check_dir_block):
* pass1.c (pass1): Add support for dynamic first inode revision.
Wed Feb 14 16:27:30 1996 <tytso@rsts-11.mit.edu>
* pass3.c (check_root): Fix spelling typo
Mon Feb 5 22:30:30 1996 <tytso@rsts-11.mit.edu>
* e2fsck.c (check_super_block): If the superblock fails certain
internal consistency checks, exit with a fatal error after
printing the "superblock is corrupt message".
Wed Jan 31 11:06:08 1996 <tytso@rsts-11.mit.edu>
* Release of E2fsprogs version 1.02
Wed Dec 15 21:24:26 1996 <tytso@rsts-11.mit.edu>
* pass1.c (process_block): Check to see if a file is "fragmented".
i.e., non-contiguous. Note that any file which is larger
than the block group is guaranteed to be non-contiguous.
We may want to use a different hueristic for deciding
whether or not a file is "fragmented".
* e2fsck.c (show_stats): Print statistics of how many
non-contiguous files are on the system.
Fri Dec 15 19:19:47 1995 <tytso@rsts-11.mit.edu>
* badblocks.c (read_bad_blocks_file, test_disk): Fold
functionality of test_disk() (which runs badblocks) into
read_bad_blocks_file(); test_disk() now calls
read_bad_blocks_file() with a NULL bad_blocks_file
argument.
Mon Nov 20 18:30:10 1995 <tytso@rsts-11.mit.edu>
* e2fsck.c (check_mount): Use #if defined(__linux__) instead of
#if defined(linux). The latter won't work if we're
compiling -ansi.
Mon Oct 30 20:31:17 1995 <tytso@rsts-11.mit.edu>
* e2fsck.c (check_mount): For Linux systems, the check to see if
the root is mounted read-only has to be done for all
filesystems, not just for the root filesystem, due to the
way that some /etc/rc scripts are set up.
Thu Oct 26 12:05:30 1995 <tytso@rsts-11.mit.edu>
* Makefile.in (install): Strip programs when they are installed.
(e2fsck): Build e2fsck statically.
Wed Oct 25 21:18:16 1995 <tytso@rsts-11.mit.edu>
* util.c (preenhalt): Preenhalt now takes an argument, which is an
ext2fs_filsys; this allows it to set the EXT2_ERROR_FS
flag in the superblock in cases where preenhalt is called.
All calls to preenhalt() were changed to either
preenhalt(fs) or preenhalt(NULL) in a few cases where the
fs pointer was not available. (Most notable, for block
read/write errors.)
Mon Sep 4 21:41:03 1995 Remy Card <card@bbj>
* ehandler.c:
util.c: Include <sys/time.h> before <sys/resource.h>. BSD needs it.
Mon Sep 4 10:14:49 1995 <tytso@rsts-11.mit.edu>
* e2fsck.c (show_stats): Show statistics about how many inodes
have indirect, doubly indirect, and triply indirect
blocks. Allow up to 8 digits for statistics, instead of
merely 6, so things look pretty for large filesystems.
* pass1.c (pass1): Keep statistics about indirect, doubly
indirect, and triply indirect blocks.
* pass1.c (unwind_pass1): Clear the above statistics when unwinding
pass 1.
Fri Aug 18 15:17:10 1995 Theodore Y. Ts'o <tytso@dcl>
* util.c, ehandler.c: Move #include of <sys/resource.h> after
#include of "e2fsck.h", since sys/resource.h may depend on
sys/time.h, which is #included in e2fsck.h.
Thu Aug 17 22:33:37 1995 <tytso@rsts-11.mit.edu>
* e2fsck.c (check_mount): Use the new ext2fs_check_if_mounted()
function to determine if the device is mounted.
* e2fsck.c (main): Add better error messages if ext2fs_open()
fails.
Wed Aug 16 16:25:02 1995 <tytso@rsts-11.mit.edu>
* pass1.c (check_blocks): If we're clearing a directory, clear
pb.is_dir so we don't do the following check of making
sure the directory size matches; this is pointless, since
we've already cleared the inode.
Fri Aug 11 09:08:54 1995 Theodore Y. Ts'o <tytso@lurch.mit.edu>
* pass1.c (bad_primary_block): New function, called by
process_bad_block, which explains the facts of life to the
user when a block in the primary superblock or primary
group descriptors is bad.
* pass2.c (check_dot): Handle the case where the first directory
entry is used, but not ".".
* pass2.c (check_dotdot): Handle the case where the second directory
entry is used, but is not "..".
Thu Aug 10 10:05:10 1995 Theodore Y. Ts'o <tytso@lurch.mit.edu>
* e2fsck.c (check_super_block): Get the size of the physical
device and if it is smaller than the reported size of the
filesystem, report an error.
Sat Aug 12 03:39:18 1995 Remy Card <card@bbj>
* e2fsck.c (check_if_skip): Print the number of allocated files and
blocks on clean filesystems.
Fri Aug 11 14:15:36 1995 Remy Card <card@bbj>
* e2fsck.8: Updated date and version number.
Thu Aug 10 14:26:01 1995 Remy Card <card@bbj>
* pass1.c (check_blocks): Check that directory size matches *exactly*
the count of allocated blocks.
Wed Aug 9 21:21:24 1995 Theodore Y. Ts'o <tytso@dcl>
* pass1b.c (pass1d): Free the shared[] array when we're done with
it to avoid a memory leak.
* pass1.c (unwind_pass1): Use ext2fs_free_block_bitmap to free the
block_dup_map.
* pass2.c (process_bad_inode): When clearing the inode, make sure
the pathname is freed, to prevent a memory leak.
* pass5.c (check_inode_bitmaps): Free free_array and dir_array
when we're finished with them.
(check_block_bitmaps): Free free_array when we're finished
with them.
* Makefile.in (e2fsck, flushb): Use $(LD) instead of $(CC) when
linking the executable.
* pass2.c (process_bad_inode): Even on OS's that don't support the
fragment fields, make sure the Linux equivalent fields are
set to zero. If an OS wants to reuse these fields, which
is probably a bad idea (although we may get desperate in
the future) this code will have to be changed.
* pass1.c (dir_block_cmp): If the block numbers are equal, compare
on the inode field, and then blockcnt field. This is just
to keep the ordering of dir_blocks the same on all
platforms when there are more than on missing directory
blocks, which are indicated directories with holes, which
are indicated with the block number being set to zero.
Sun Aug 6 15:40:58 1995 Theodore Y. Ts'o <tytso@lurch.mit.edu>
* pass1.c (check_blocks, process_block): check_blocks() modified
to call the ext2fs_block_iterate() with BLOCK_FLAG_HOLE if
the inode is a directory. process_block() now checks to
see if a directory has a "hole", or missing block. If so,
this fact is recorded in the directory block list so that
the problem can be resolved in pass #2.
* pass2.c (allocate_dir_block): Added allocate_dir_block() to
allocate new blocks for directories with "holes". Called
out of check_dir_block if a block in the directory block
list is zero.
* pass3.c (get_lost_and_found): Move location of free(block) to
prevent possible memory leak.
Sat Aug 5 12:42:22 1995 Theodore Y. Ts'o <tytso@lurch.mit.edu>
* pass2.c (check_dir_block): Use a automatic, fixed-saize array
instead of alloca() --- alloca is not portable! Check to
make sure the filename is not longer than EXT2_NAME_LEN,
and offer to fix it by truncating it, since it should
never happen.
* e2fsck.c (PRS): Use malloc() instead of alloca() --- alloca() is
not portable!! In any case putenv() in some systems must
take a static character array or malloc()'ed memory;
passing memory allocated using alloca() to putenv() is not
advisable.
* pass2.c (check_dot, check_dotdot): Use malloc() instead of
alloca() --- alloca() is not portable!!!
Tue Jul 18 20:04:02 1995 <tytso@rsx-11.mit.edu>
* pass1b.c (pass1c):
* pass3.c (check_root, get_lost_and_found):
* pass2.c (check_dir_block): Use ext2fs_{read,write}_dir_block
to read/write the directory block.
Mon Jul 17 04:00:56 1995 <tytso@rsx-11.mit.edu>
* util.c (ask_yn): Apply patch supplied by Peter A. Zaitcev to
make sure VMIN and VTIME are set correct.
Fri Jul 14 19:26:29 1995 <tytso@rsx-11.mit.edu>
* pass1.c (mark_block_used): Change to be an inline function.
Assume that the block validity checks are already done,
and use the fast variant of the bitmap functions.
Thu Jul 13 08:10:55 1995 <tytso@rsx-11.mit.edu>
* pass5.c (check_block_bitmaps, check_inode_bitmaps): Check the
bounds of the bitmaps in advance, and then use the fast
variant of e2fs_test_{block,inode}_bitmap.
* pass1.c (mark_block_used): Use ext2_fast_mark_block_bitmap since
the bounds checking has already been done earlier.
Wed Jul 12 02:22:46 1995 <tytso@rsx-11.mit.edu>
* pass1.c (pass1): Allocate and free the block_illegal_map, which
is used for shortcut processing in process_block.
(mark_table_blocks): Initialize block_illegal_map with the
filesystem blocks.
(describe_illegal_block): New helper function that
describes why a block is illegal.
(process_block): Use block_illegal_map as a shortcut
to determine whether a block is bad. Use
describe_illegal_block to print out why the block is illegal.
Mon Jun 12 19:11:06 1995 Theodore Y. Ts'o (tytso@dcl)
* flushb.c: Don't include <linux/fs.h> if it doesn't exist.
* scantest.c: Don't include <linux/fs.h>, <getopt.h>, or
<mntent.h> if they don't exist. (Mostly so that "make
depend" works.)
* pass1.c, pass1b.c, pass3.c, badblocks.c: Include <errno.h> (if
it exists).
* e2fsck.c, scantest.c: Don't include <getopt.h> if it doesn't
exist.
Mon Jun 12 08:37:49 1995 Theodore Y. Ts'o <tytso@lurch.mit.edu>
* pass2.c (process_bad_inode, check_for_zero_long,
check_for_zero_char): Change long to u32, and char to u8.
Sun Jun 11 15:05:57 1995 Theodore Y. Ts'o <tytso@lurch.mit.edu>
* util.c (inode_has_valid_blocks):
* pass2.c (process_bad_inode):
* pass1.c (pass1, check_blocks, pass1_check_directory): Use
LINUX_S_IS* instead of S_IS*.
* e2fsck.h: Don't #include <sys/stat.h>
* flushb.c (main): Add #ifdef BLKFLSBUF around ioctl. (Although
this program is pretty much useless if BLKFLSBUF isn't
supported.)
* e2fsck.c, badblocks.c: Add #include <errno.h>, since errno is
used.
Thu Jun 8 12:31:19 1995 Miles Bader <miles@churchy.gnu.ai.mit.edu>
* pass2.c (check_dot, check_dotdot, check_dir_block): Use alloca
to allocate space for file names instead of using fixed size buffers.
(process_bad_inode): Only check inode frag fields if
HAVE_EXT2_FRAGS is defined (by configure).
* pass1.c (pass1): Only check the inode frag fields if
HAVE_EXT2_FRAGS is defined (by configure).
* e2fsck.c (check_mount): Only check for a mounted filesystem if
HAVE_MNTENT_H is defined (by configure).
(PRS): Use alloca to allocate the new path string, instead of
having a fixed size buffer (which was the wrong size anyway).
(PRS): Only support the -F (flush) option if the BLKFLSBUF ioctl
is defined.
* e2fsck.h: Only include <linux/fs.h> if HAVE_LINUX_FS_H is
defined (by configure).
* Makefile.in: Rewritten to conform to GNU coding standards and
support separate compilation directories.
Thu Apr 6 15:04:36 1995 Remy Card <card@bbj.ibp.fr>
* pass1.c (pass1): Test the mode in reserved inodes (must be zero).
Sat Mar 11 13:12:16 1995 Theodore Y. Ts'o <tytso@localhost>
* pass1.c (unwind_pass1): Clear the file type statistics counter
when pass 1 needs to be restarted from scratch.
* pass1.c (handle_fs_bad_blocks): Fix bug where bitmap blocks were
being reallocated to blocks in the next block group,
instead of the current block grup.
* pass1.c (pass1, check_blocks): Set inode_link_info[ino] whenever
inode.i_links_count is set.
Tue Feb 14 01:38:04 1995 Theodore Y. Ts'o (tytso@rt-11)
* pass1.c (process_block): Add checks for if the block is
trepassing on a superblock or group descriptor table.
Sat Dec 31 00:52:11 1994 <tytso@rsx-11.mit.edu>
* main.c (corrupt_msg): Extend the message which is printed out
when the superblock is corrupt, to include the suggestion
of using the -b option to specify an alternate superblock.

* badblocks.c (read_bad_blocks_file): If we are adding or
replacing bad blocks in the bad blocks inode, sanity check
the bad block inode first, and clear out any illegal blocks.
* pass2.c (check_name): Don't bomb out if the attempt to get the
pathname of the containing directory returns an error; the
directory may be too badly damaged to expect that
ext2fs_get_pathname will always succeed. Use "???" if the
pathname can't be obtained (it's only for a printf to the
user anyway).
The name of the containing directory and the bad filename
were incorrectly interchanged in the user message. Fixed.
* pass2.c (check_name, check_dir_block): Use a common static
string for the unknown pathname.

* Fixed lots of printf formats to make sure that block and inode
numbers are printed as unsigned integers.
Mon Oct 24 14:10:46 1994 (tytso@rsx-11)
* pass5.c (check_block_end): Fix calculation of how the last block
in the block bitmap should be calculated.
Wed Sep 7 10:01:13 1994 (tytso@rsx-11)
* pass1b.c (pass1_dupblocks): Fix declaration of dup_inode_map to
be an ext2fs_inode_bitmap, and free it properly.
* e2fsck.h
* e2fsck.c (main): Folded in Remy Card's changes to add a revision
level to the superblock.
Wed Aug 17 22:00:20 1994 Remy Card (card@bbj)
* e2fsck.c (usage): Fixed bogus usage message.
Wed Aug 17 11:21:45 1994 Theodore Y. Ts'o (tytso@rt-11)
* pass1.c (process_bad_block): Fixed bug so that blocks in the
backup superblocks and group descriptors are handled gracefully.
