journal.c, pass1.c, super.c, unix.c: Replace use of struct ext2fs_sb
with struct ext2_super_block.
ChangeLog, debugfs.c:
debugfs.c Replace use of struct ext2fs_sb with struct ext2_super_block.
|
|
super.c (release_orphan_inodes): Fix spelling typo in error message.
ChangeLog, unix.c:
unix.c (main): Clarify coments (no code changes)
ChangeLog, journal.c:
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): If we're doing a read-only check, skip the journal
playback, but don't abort the e2fsck run.
|
|
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.
|
|
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().
debugfs.c:
debugfs.c (finish_range): Make sure the pager FILE pointer to use.
configure, configure.in, ChangeLog:
configure.in (JFS_DEBUG): Add support for --enable-jfs-debug
|
|
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
jfs.h, recovery.c: Files ext3 kernel code.
jfs_compat.h: Compatibility header file to allow kernel code to be
linked to e2fsck.
|
|
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...)
|
|
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.
|
|
Makefile.in (install): Install resize2fs in /sbin, not /usr/sbin.
ChangeLog, unix.c:
unix.c: 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.
ChangeLog:
Fix minor wording error in Chagelog.
|
|
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).
|
|
badblocks.c, dumpe2fs.c, e2label.c, mke2fs.c, tune2fs.c, uuidgen.c:
For platforms that don't define optarg.h, manually define optarg and
optind.
ChangeLog, main.c:
main.c: For platforms that don't define optarg.h, manually define
optarg and optind.
ChangeLog, unix.c:
unix.c: For platforms that don't define optarg.h, manually define
optarg and optind.
|
|
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.
|
|
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.
ChangeLog, Makefile.in:
Makefile.in: Exclude the internationalization files from being
distributed.
ChangeLog, configure, configure.in:
configure.in: Add support for --enable-compression. This is
experimental code only for now, which is why it's under --enable test.
Once it's stable, it will always be compiled in.
TODO:
Commit additional TODO items.

|
bitops.h (ext2fs_mark_generic_bitmap, ext2fs_unmark_generic_bitmap,
ext2fs_mark_block_bitmap, ext2fs_unmark_block_bitmap,
ext2fs_mark_inode_bitmap, ext2fs_unmark_inode_bitmap): Change to
return the previous state of the bit that is being marked or unmarked.
For speed optimization.
ChangeLog, pass3.c:
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.
ChangeLog, Makefile.in, e2fsck.h, unix.c:
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.
|
|
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>.
|
|
pass4.c (e2fsck_pass4): Clear inode_imagic_map after freeing it, to
prevent it from getting freed twice.
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.
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.
problem.h (PR_2_SPLIT_DOT): Fix excess zero in problem code (now
matches the standard convention).
|
|
unix.c (PRS), util.c (ask_yn): Add #ifdef's to make e2fsprogs easier
to port to non-Unix platforms.
|
|
unix.c (usage): Add minimalist emergency help to the usage message.
|
|
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.
|
|
unix.c (check_mount): Clean up the abort message displayed when the
filesystem is mounted and either stdout or stdin isn't a tty.
|
|
dir_iterate.c (ext2fs_process_dir_block): Check for corrupted
directory entry before calling the callback function. This should
prevent some core dumps of insufficiently paranoid callback functions.
ChangeLog, unix.c:
unix.c (main): Add missing space in the disk write-protected message.
|
|
unix.c (reserve_stdio_fds): Add safety check in case reserve_stdio_fds
couldn't open /dev/null.
|
|
unix.c (main): Reset the context before calling ext2fs_close(), to
avoid referencing already freed memory.
ChangeLog, llseek.c:
llseek.c (ext2fs_llseek): Change ext2fs_llseek() in the non-Linux case
to use EINVAL by default, unless it isn't defined, in which case we
use EXT2_ET_INVALID_ARGUMENT instead.
ChangeLog, mk_cmds.sh.in:
mk_cmds.sh.in: Fixed portability bug in shell script; we were
depending on a bash'ism.
ChangeLog, uuid.c:
uuid.c: Use asm/types.h instead of linux/types.h, to be consistent
with other locations where we've had to do this to work around glibc.
|
|
tune2fs.8.in: Fix minor display bug in the nroff.
mke2fs.c (show_stats, write_inode_tables): Use the log10 function to
calculate the display of block numbers so that things look nice on an
80 character display.
mke2fs.c (usage): Add the sparse-super-flag to the usage message.
ChangeLog, e2fsck.c, pass1.c, pass2.c, problem.c, problem.h, unix.c:
unix.c (main): Move ext2fs_close() after e2fsck_free_context() since
e2fsck_free_context may reference data in ctx->fs.
e2fsck.c (e2fsck_reset_context): Make sure ctx->fs is non-NULL before
checking ctx->fs->dblist.
pass1.c (e2fsck_pass1): Use the device check subroutine on FIFO's and
Socket's, so that we catch bogus immutable inodes.
pass2.c (process_bad_inode): Process bad socket and fifo's.
problem.h, problem.c: Define new problem codes PR_2_BAD_FIFO and
PR_2_BAD_SOCKET.
|
|
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.
|
|
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.
emptydir.c:
Commit partially done file.
ChangeLog, badblocks.c:
badblocks.c (ext2fs_badblocks_list_add): Use a bigger increment than
10 blocks when we need to expand the size of the badblocks list.
|
|
unix.c (main): Fix typo in checking the incompat feature set; it
should be checked against EXT2_LIB_FEATURE_INCOMPAT_SUPP.
|
|
Add a -V option which displays the current version.
ChangeLog, unix.c:
unix.c (e2fsck_update_progress): Remove unused variables.
ChangeLog, inode.c:
inode.c (get_next_blockgroup): Fix bug where if get_next_blockgroup()
is called early because of a missing inode table in a block group, the
current_inode counter wasn't incremented correctly.
ChangeLog, tst_uuid.c:
tst_uuid.c (main): Fixed bogus declaration of the main's argv parameter.
ChangeLog, test_icount.c:
test_icount.c (main): Fix main() declaration so that it returns int,
not void.
Many files:
fsck.c (ignore): Remove unused variable cp.
chattr.c (fatal_error):
tune2fs.c (usage):
lsattr.c (usage):
dumpe2fs.c (usage):
badblocks.c (usage): Remove volatile from declaration.
fsck.c: Change use of strdup to be string_copy, since we don't trust
what glibc is doing with strdup. (Whatever it is, it isn't pretty.)
|
|
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.
|
|
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.
ChangeLog, expect.1:
f_messy_inode: Modify test to deal with changes to support 64-bit size
files. (/MAKEDEV had i_dir_acl, now i_size_high, set.)
|
|
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.
|
|
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.
|
|
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++.
unix.c (sync_disk): Remove sync_disk and calls to that function,
since ext2fs_close() now takes care of this.
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.
|
|
pass1.c, pass2.c, pass3.c, pass4.c, pass5.c: Add calls to the progress
indicator function.
pass1.c (scan_callback): Add call to the progress feedback function
(if it exists).
super.c (check_super_block): Skip the device size check if the
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().
problemP.h:
New file which contains the private problem abstraction definitions.
Makefile.pq:
Remove include of MAKEFILE.STD, which doesn't exist at this point.
|
|
Add a special case check for the error code EROFS and display an
appropriate error message for this case.
|
|
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.
|
|
fsck.c:
chattr.c: Remove #include of getopt.h, since it's not needed.
tune2fs.c (main):
lsattr.c (main):
badblocks.c (main):
dumpe2fs.c (main):
mke2fs.c (PRS): Make the variable which getopt returns into be
an int, so that it won't lose on platforms where char is
unsigned.
ChangeLog, unix.c:
Make the variable which getopt returns into be an int, so that it
won't lose on platforms where char is unsigned.
|
|
Place #ifdef RESOURCE_TRACK around code which uses init_resource_track
and print_resource_track. (Not all systems have timeval)
|
|
pass*.c, super.c: Massive changes to avoid using printf and com_err
routines. All diagnostic messages are now routed through the
fix_problem interface.
pass2.c (check_dir_block): Check for duplicate '.' and '..' entries.
problem.c, problem.h: Add new problem codes PR_2_DUP_DOT and
PR_2_DUP_DOT_DOT.
problem.c: Added new problem codes for some of the superblock
corruption checks, and for the pass header messages. ("Pass
1: xxxxx")
util.c (print_resource_track): Now takes a description argument.
super.c, unix.c, e2fsck.c: New files to separate out the
operating-specific operations out from e2fsck.c. e2fsck.c now
contains the global e2fsck context management routines, and
super.c contains the "pass 0" initial validation of the
superblock and global block group descriptors.
pass1.c, pass2.c, pass3.c, pass4.c, pass5.c, util.c: Eliminate
(nearly) all global variables and moved them to the e2fsck
context structure.
problem.c, problem.h: Added new problem codes PR_0_SB_CORRUPT,
PR_0_FS_SIZE_WRONG, PR_0_NO_FRAGMENTS, PR_0_BLOCKS_PER_GROUP,
PR_0_FIRST_DATA_BLOCK
expect.1, expect.2:
Updated tests to align with e2fsck problem.c changes.
