E2fsprogs 1.31 (Nomvember 8, 2002)
|
|
==================================
|
|
|
|
Update EVMS ext2fsim plugin with EVMS 1.2. (We still support
|
|
compiling the fsim plugin with EVMS 1.0 and 1.1.) Add better error
|
|
handling for child process that die unexpectly. Add a hack to force
|
|
mkfs to create filesystems that won't cause problems with hardware
|
|
that has 2k or 4k minimum blocksize requirements. Read from child
|
|
processes in non-blocking mode, so that the GUI continues to update.
|
|
|
|
Fix e2fsck so that it returns the appropriate exit code when the root
|
|
filesystem has been changed, so that system's rc scripts will be told that
|
|
the system needs to be rebooted.
|
|
|
|
Fix a bug in ext2fs_flush/ext2fs_close; when the MASTER_SB_ONLY flag
|
|
was set, some of the descriptor blocks that should have been written
|
|
out were getting skipped.
|
|
|
|
Changed e2fsck to force out changes to the backup copies of the
|
|
superblock and block group descriptors when important changes are made
|
|
to those data structures.
|
|
|
|
Fix a bug where e2fsck could erroneously mark a filesystem as being
|
|
clean if a check of dirty filesystem is interrupted with a ^C. (Bug
|
|
introduced in e2fsprogs 1.28.)
|
|
|
|
If journal debuging is enabled using --enable-jbd-debug, the debugging
|
|
level is now set via the E2FSCK_JBD_DEBUG environment variable.
|
|
|
|
If byteswapping support is disabled using configure --disable-swapfs,
|
|
skip the tests which depend on byte-swapping, so that "make check"
|
|
won't bomb out.
|
|
|
|
Lshattr will now display the indexed directory flag. Also, some of
|
|
the more esoteric compression flags are supressed unless compression
|
|
support has been enabled.
|
|
|
|
Update man pages.
|
|
|
|
|
|
E2fsprogs 1.30 (October 31, 2002)
|
|
=================================
|
|
|
|
When resizing a filesystem, and inodes need to moved, resize2fs will
|
|
update the inode's ctime field, and the mtime field of the containing
|
|
directories, so that incremental backups using dump/restore will work
|
|
correctly.
|
|
|
|
In order to avoid spurious errors, e2fsck wil check the last
|
|
superblock write time to determine whether or not it can safely use
|
|
the LOW_DTIME checks to determine if there are inodes on the orphan
|
|
inode linked list that had somehow gotten disconnected. (Addresses
|
|
Sourceforge bug #620980)
|
|
|
|
Partition in /proc/partitions that being with the string "lvm" are
|
|
considered real partitions even if they do not end with a number.
|
|
|
|
Fixed a bug in the the uuid generation function, where if /dev/urandom
|
|
is not present, but /dev/random is, and there isn't sufficient
|
|
entropy, the get_random_byte function could spin a loop forever.
|
|
|
|
E2fsck, mke2fs, etc. will now reliably notice when image files are
|
|
mounted using the loopback interface. (Addresses Sourceforge bug
|
|
#619119)
|
|
|
|
When flushing buffers (as is done by badblocks, for example) check to
|
|
see if the BLKFLSBUF ioctl succeeds, and if so, avoid using the
|
|
FDFLUSH ioctl which causes the MD device driver which causes confusing
|
|
syslog messages about obselete ioctl messages. (Addresses Sourceforge
|
|
bug #545832).
|
|
|
|
Debugfs's write command now checks to see if the destination filename
|
|
exists before creating it. (Addresses Sourceforge bug #478195.)
|
|
|
|
When installing man pages, search for compressed man pages using all
|
|
commonly used compression extensions (i.e., .Z, .gz, .bz2, etc.)
|
|
|
|
Fixed a bug in fsck where multiple filesystems specified on the
|
|
command were not being checked in parallel due to a logic bug
|
|
introduced to support the FSCK_MAX_INST environment variable.
|
|
|
|
We have added a new superblock field, s_mkfs_time, which indicates
|
|
when a filesystem was created. It is set via mke2fs, and printed out
|
|
by dumpe2fs, but is not actually touched by the kernel.
|
|
|
|
Dumpe2fs has been made more robust by not aborting if there is an
|
|
error reading the block/inode bitmaps; instead it will still print out
|
|
the location of the block/inode bitmaps and inode table.
|
|
|
|
Add support for the an alternative block group descriptor layout which
|
|
allows for on-line resizing without needing to prepare the filesystem
|
|
in advance. (This is the incomat feature flag meta_bg.)
|
|
|
|
Add support for storing default mount options in the superblock, so
|
|
that the filesystem can be mounted with specific mount options without
|
|
needing to specify them on the mount command line or in the /etc/fstab
|
|
file.
|
|
|
|
Add support for a new inode flag, which is to be used for indicating
|
|
the top of directory hierarchies for the Orlov block allocator.
|
|
|
|
Fix e2fsck so that if it creates the lost+found directory, it does so
|
|
with the more apporpriate permissions of 0700. Also change
|
|
mklost+found so that it also creates the directory 0700.
|
|
|
|
Fixed format bug in e2fsck if NLS is in use.
|
|
|
|
Add a German translation for e2fsprogs's NLS support.
|
|
|
|
Fixed e2fsck so that it more handles BAD_BLOCK_IN_INODE_TABLE even at
|
|
the beginning of the inode table. This won't matter much, since if
|
|
there is a bad block at the beginning of the inode table, the root
|
|
directory won't be available. But at least e2fsck won't crash in this
|
|
case.
|
|
|
|
Fixed endian problems in the htree code for e2fsck and debugfs.
|
|
|
|
When byte-swapping a filesystem on a PPC architecture, byte-swap the
|
|
bitmaps since the historical big-endian ext2 variant had byte-swapped
|
|
bitmaps, and the ext2fs library assumes this. This fixes the
|
|
regression test suite on PPC machines.
|
|
|
|
Fix e2image so that it handles a bad block in the inode table
|
|
appropriately.
|
|
|
|
E2fsck now uses a more sophisticated algorithm to salvage corrupted
|
|
directories that recovers more information in the corrupted directory
|
|
block.
|
|
|
|
E2fsck now performs additional consistency checks on indexed (HTREE)
|
|
directories.
|
|
|
|
Fix bug where efsck might get confused about whether a completely
|
|
empty directory block is an empty leaf block or an interior htree
|
|
node. This could cause e2fsck to get confused into think that a valid
|
|
indexed directory was corrupted.
|
|
|
|
E2fsck no longer creates an empty directory entry at the end of a
|
|
directory block when optimizing a directory. This would cause some
|
|
earlier versions of the dxdir kernel code to corrupt the directory
|
|
when attempting to split a node containing an empty directory entry.
|
|
|
|
E2fsck could sometimes in rare circumstances leave the indexed flag
|
|
set after a small directory was optimized by compressing it instead of
|
|
indexing it. (This should never happen in real life, since
|
|
directories that small wouldn't have been indexed, but better safe
|
|
than sorry.)
|
|
|
|
E2fsck now only updates the master superblock in all cases. This
|
|
slightly shortens its run time.
|
|
|
|
Ext2ed can deal with directory entries of length 0; previously it
|
|
would get stuck in an infinite loop.
|
|
|
|
Fsck now has support for reiserfs volumes when parsing LABEL= and UUID=
|
|
specifiers. (Sourceforge patch #613447)
|
|
|
|
Badblocks will now work correctly on read-only devices such as
|
|
CD-ROM's. (Sourceforge patch #600451)
|
|
|
|
Updated and clarified man pages. (Addresses Debian bug #167108)
|
|
|
|
|
|
E2fsprogs 1.29 (September 24, 2002)
|
|
===================================
|
|
|
|
Fixed a bug in e2fsck which could corrupt a directory when optimizing
|
|
it (via the -D option) or rebuiliding the hash tree index with a 1 in
|
|
512 probability, due to a fence post error.
|
|
|
|
Fixed a bug in the LVM support code which caused LABEL='xxx' not to
|
|
work correctly.
|
|
|
|
Mke2fs now enables the directory indexing flag by default. (Since
|
|
this is a compatible feature flag, it's safe to do so.)
|
|
|
|
Tune2fs will support setting the directory indexing feature flag. It
|
|
will automatically set up the default hash algorithm and hash seed
|
|
fields in the superblock.
|
|
|
|
If the bone-headed user enters the root filesystem twice in
|
|
/etc/fstab, the -R option which skips the root filesystem will skip
|
|
all of them. (Addresses Debian bug #159423). Note! This is not a
|
|
precedent for dealing intelligently with any other kind of doubled
|
|
entry in /etc/fstab!
|
|
|
|
|
|
Programmer's notes:
|
|
-------------------
|
|
|
|
Removed perror declaration in lib/et/internal.h. All modern systems
|
|
can be expected to define perror() these days. Besides, the lib/et
|
|
code wasn't using perror at all anyway. :-)
|
|
|
|
|
|
E2fsprogs 1.28 (August 31, 2002)
|
|
================================
|
|
|
|
Add support for the Hashed-Tree Directory Indexing to e2fsck. Support
|
|
for setting the htree flag is not included yet, although it can be
|
|
manually turned on via the debugfs program.
|
|
|
|
Clarified e2fsck error message which is printed when it cannot find
|
|
sufficient contiguous block when relcating filesystem metadata.
|
|
|
|
Added support for building an EVMS plugin module for ext2/3. This
|
|
module is substantially the same as the EVMS module shipping with EVMS
|
|
1.1, with one or two bugfixes. E2fsprogs can also build this plugin
|
|
for use with EVMS 1.0 (which did not include the ext2 plugin module),
|
|
if the configure --enable-old-evms flag is given.
|
|
|
|
Fsck will search through EVMS volumes when trying to resolve
|
|
filesystem specifications such as LABEL=xxx or UUID=xxx.
|
|
|
|
Added a new utility program, /sbin/findfs, which will return
|
|
filesystem specifications such as LABEL=xxx or UUID=xxx, and prints
|
|
the device name.
|
|
|
|
Update and clarified various man pages. (addresses Debian Bug #145044,
|
|
#146437, #131350, #151990, #144621, #141938)
|
|
|
|
If there are no filesystems specified on fsck's command line, fsck now
|
|
treat that as if the -As options were given. Previously it would
|
|
simply do nothing. (Addresses Debian Bug #153102)
|
|
|
|
Mke2fs no longer treats a failure to be able to clear the MD signature
|
|
at the end of the filesystem as a fatal error. (Addresses Debian Bug
|
|
#155007)
|
|
|
|
The e2p library functions (which are used by lsattr and chattr) now
|
|
double check to make sure the file is a regular file or directory
|
|
before attempting to use the ext2 ioctls. Some device drivers
|
|
unfortunately respond to the ext2 ioctl's with unknown behaviour.
|
|
(Addresses Debian Bug #152029).
|
|
|
|
The extended attribute handling has been updated to correspond with
|
|
the latest V2 bestbits ACL code.
|
|
|
|
Fixed bug in e2fsck which caused it to not clear the dtime field when
|
|
processing truncated inodes on the orphan list. This could cause data
|
|
loss(!) if a filesystem is rebooted before a truncate has been
|
|
committed.
|
|
|
|
E2fsck now uses red/black trees in pass1b, which removes some O(n**2)
|
|
algorithms. This makes e2fsck much faster in the case of severely
|
|
corrupted filesystems where a large number of blocks are claimed by a
|
|
large number of inodes. (Thanks to the 2.5 IDE device driver for
|
|
inspiring this work.)
|
|
|
|
Resize2fs has been significantly sped up when shrinking and expanding
|
|
a filesystem by a very small number of blocks (for example, when EVMS
|
|
is converting a partition to be an EVMS legacy volume).
|
|
|
|
Added a new option to e2fsck, -D, which will optimize or compress all
|
|
of the directories in the filesystem.
|
|
|
|
E2fsck now catches SIGINT and SIGTERM to make sure it will can
|
|
properly clean up and only exit at safe points. Fsck will pass
|
|
SIGINT/SIGTERM to its child processes, and wait until they have all
|
|
exited before it exits.
|
|
|
|
The uuid parsing code in the uuid library now properly complains when
|
|
an illegally formated uuid is presented to it. (Addresses Debian bug
|
|
#152891)
|
|
|
|
Restrict use of the 2.4 setrlimit ABI f*ckup to kernels between 2.4.10
|
|
and 2.4.17, since the workaround can cause problems when using a 2.4
|
|
kernel with an old version of glibc built with the 2.2 headers.
|
|
|
|
Fixed a bug in mke2fs where it wasn't properly clearing the initial
|
|
superblock used by other filesystems. (Addresses Debian bug #147256.)
|
|
|
|
Added support for the synchronous directory feature written by Andrew
|
|
Morton.
|
|
|
|
The debugfs program can delete directories using the rmdir command.
|
|
|
|
Add support for 8k and 16k filesystems (for systems with page sizes
|
|
that are greater or equal to 8k or 16k, respectively). Note that
|
|
these filesystems can not be mounted on x86 systems, or other systems
|
|
with only 4k page sizes, due to limitations in the current Linux VM
|
|
code.
|
|
|
|
Resize2fs requires that the filesystem state be valid and have no
|
|
errors; otherwise, e2fsck -f must be run first. (Previously it simply
|
|
required that the last fsck time be greater than the last mount time.)
|
|
|
|
Configure now defaults the man pages directory to /usr/share/man on
|
|
Linux systems.
|
|
|
|
E2fsck now offers to truncate inodes which contain too many blocks (so
|
|
that i_blocks would overflow. Also fixed handling of large sparse
|
|
files.
|
|
|
|
E2fsck now more completely checks for symlink validity, including
|
|
requiring NULL termination and length checks.
|
|
|
|
E2fsck will offer to try forcing a disk write to remap a bad block
|
|
after finding a read error when reading a filesystem metadata block.
|
|
|
|
Fixed a bug in debugfs which caused the -b and -s options to crash
|
|
debugfs, as well as breaking the testb, setb, and clearb functions.
|
|
|
|
Added a bmap command to debugfs which calculates the logical to
|
|
physical block mapping for a particular inode.
|
|
|
|
Fixed a bug in code which checked to see if a device was mounted which
|
|
sometimes (rarely) failed in the case of a plain file.
|
|
|
|
Fixed a bug in resize2fs where when it reported an error, it would
|
|
print a message erroneously indicating that the filesystem had been
|
|
resized before it aborted.
|
|
|
|
When resizing a plain file which is smaller than the requested size,
|
|
resize2fs will attempt to extended the file so that programs like
|
|
e2fsck will not complain that the file is too small.
|
|
|
|
Resize2fs will print the actual new size of the filesystem when it is
|
|
finished resizing.
|
|
|
|
Fixed a bug in debugfs where "ls -l" would report incorrectl file type
|
|
information on big-endian systems.
|
|
|
|
|
|
Programmer's notes:
|
|
-------------------
|
|
|
|
Fixed collisions with C++ reserved words.
|
|
|
|
Added portability fixes for building e2fsprogs on the HURD and AIX.
|
|
|
|
Added the ext2ed program for creation of test cases. (ext2ed has many
|
|
limitations and bugs which make it unsuitable for production use.)
|
|
|
|
The ext2fs_read_dir_block2 and ext2fs_write_dir_block now take a new
|
|
flag, EXT2_DIRBLOCK_V2_STRUCT, which will will reverse when the
|
|
name_len field is byte swampped on big-endian machines, since in the
|
|
V2 structure, name_len is a char field which is doesn't need to be
|
|
byte swapped --- except if an old-style kernel had byte-swapped the
|
|
name_len field as part of the V1 structure.
|
|
|
|
|
|
E2fsprogs 1.27 (March 8, 2002)
|
|
==============================
|
|
|
|
The warning messages for mke2fs now go to standard error.
|
|
|
|
Fixed to make sure "make check" runs all of the test programs with
|
|
LD_LIBRARY_PATH set, so that we test the libraries in the build tree.
|
|
|
|
The mke2fs program checks the boot sector for the BSD disk label, and
|
|
avoids erasing it if it is there.
|
|
|
|
Fixed a bug in e2fsck which caused it to core dump if the journal
|
|
inode was missing when it was supposed to be there.
|
|
|
|
E2fsck now prints ranges in pass 5 when printing deltas for the block
|
|
and inode bitmaps.
|
|
|
|
Debugfs's "ls -l" command now will print out the file type information
|
|
in the directory entry.
|
|
|
|
Create man pages and hard links for fsck.ext3 and mkfs.ext3. If
|
|
mke2fs is invoked as mkfs.ext3, create the filesystem with a journal.
|
|
|
|
Debugfs can now examine the experimental directory indexing
|
|
information.
|
|
|
|
Fixed bug in debugfs which caused it to core dump if modify_inode is
|
|
called without an open filesystem.
|
|
|
|
The debugfs lsdel command now runs its output through a pager first.
|
|
|
|
When installing manual pages, remove the compressed manual pages first.
|
|
|
|
Synchronized with Debian's packaging information for e2fsprogs-1.26-1.
|
|
|
|
Fix the 2.4 resource limitation workaround introduced in 1.26 which
|
|
actually broke things on mips32, sparc32, and Alpha platforms.
|
|
|
|
Updated the I18N code so that calls to setlocate(LC_CTYPE, 0) are made
|
|
(which is required by the newer libintl libraries).
|
|
|
|
Programmer's notes:
|
|
-------------------
|
|
|
|
Fixed various gcc -Wall complaints.
|
|
|
|
Fixed a few memory leaks in the e2fsck journaling code, and in the
|
|
ismounted code checking for a swap device.
|
|
|
|
Add new inode I/O abstraction interface which exports an inode as
|
|
an I/O object.
|
|
|
|
Exported ext2_file_flush as a public interface.
|
|
|
|
In ext2_file_write, we now mark the buffer void * argument as a const, since ext2_file_write doesn't modify the buffer.
|
|
|
|
Lots of small random portability fixes to make e2fsprogs build under
|
|
AIX --- even without the 5L compatibility toolkit, and even using the
|
|
uber-crippled AIX native C compiler.
|
|
|
|
|
|
E2fsprogs 1.26 (February 3, 2002)
|
|
=================================
|
|
|
|
Dumpe2fs will keep going now if the bad block inode can't be read.
|
|
(Previously it stopped with a fatal error.)
|
|
|
|
E2fsck will now give an opportunity to run the journal even if the
|
|
recovery flag is not set. This is the default behaviour if e2fsck is
|
|
using a backup superblock, since the needs_recovery flag will never be
|
|
set in the backup superblock copies.
|
|
|
|
E2fsck now automatically finds the backup superblock/group descriptors
|
|
even when the primary superblock is completely destroyed for 2k and 4k
|
|
filesystems. (Previously it just guessed/assumed that we were dealing
|
|
with a 1k filesystem in that case, and users had to manually specify
|
|
the backup superblock number.)
|
|
|
|
Fixed a bug in e2fsck where it dereferences a null pointer when there
|
|
is a problem opening a filesystem in preen mode.
|
|
|
|
E2fsck now handles external journals correctly; previously it trashed
|
|
the external journal device if the journal needed to be replayed.
|
|
|
|
Work around ulimit incompatibility problem caused by recent 2.4
|
|
kernels; the unix IO module will automatically try to set any resource
|
|
limits to be infinite on startup.
|
|
|
|
Fixed a bug in e2fsck where it wasn't allocating a new block or inode
|
|
bitmap if it wasn't present and the blocksize was 2k or 4k.
|
|
(Addresses Debian Bug #116975)
|
|
|
|
E2fsck will check and fix botched ext3 V1 to V2 superblock updates by
|
|
clearing the new V2 fields if they do not make sense or if the ext3
|
|
superblock is version 1 superblock.
|
|
|
|
E2fsck will automatically relocate the ext3 journal from a visible
|
|
file (i.e., /.journal) to an hidden inode if the filesystem has been
|
|
opened read/write. This allows the users to add a journal while the
|
|
filesystem is mounted, but the next time the system is rebooted, the
|
|
journal file will disappear. This avoids problems with backups,
|
|
stupid operators with superuser bits, etc.
|
|
|
|
Fix a bug in fsck where it would not support a filesystem type of
|
|
"auto" if the device was specified in terms of LABEL=xxx or UUID=xxx.
|
|
|
|
Fsck now supports fstab entries of the form "ext3,ext2". It will also
|
|
automatically identify reiserfs filesystems.
|
|
|
|
The number of processes spawned by fsck can now be limited using the
|
|
FSCK_MAX_INST environment variable.
|
|
|
|
Fsck now searchs the LVM proc hierarchy to find logical volumes which
|
|
should be searched for UUID and label information.
|
|
|
|
Work around a bug in 2.4.10+ kernels by trying to unset the filesize
|
|
limit if at all possible, when opening a block device. (The filesize
|
|
limit shouldn't be applied against writes to a block device.)
|
|
|
|
In mke2fs and e2fsck, specifying the -c option twice will now do
|
|
a read/write test on the disk. Update the man pages to encourage
|
|
using the -c option, and to discouraging running badblocks separately,
|
|
since users tend to forget to set the blocksize when running
|
|
badblocks.
|
|
|
|
Mke2fs now automatically clears the immutable attribute on a
|
|
pre-existing .journal file left over from a previous failed attempt to
|
|
add a journal to an alreadyy-mounted filesystem.
|
|
|
|
Fixed mke2fs's exit codes to consistently indicate when the mke2fs
|
|
operation failed.
|
|
|
|
Mke2fs now creates the lost+found directory with permissions of 0700,
|
|
so that files that had previously lived in protected directory are
|
|
safe if they get dropped in lost+found and the system administrator
|
|
doesn't deal with immediately. (Addresses Debian #bug 118443)
|
|
|
|
Mke2fs and e2fsck (and all programs that use the
|
|
ext2fs_check_if_mounted function) will now properly identify that a
|
|
device is mounted, even in cases where devfs has confused things with
|
|
multiple devices names with the same identity, or if a dim-witted
|
|
system administrator has done something stupid like creating device
|
|
file aliases in their home directory. Also now checks for swap devices
|
|
by using /proc/swaps. (Addresses Debian bug #106622)
|
|
|
|
Added a new option (-T) to tune2fs which sets the time a filesystem
|
|
was last checked.
|
|
|
|
Speed up e2image when creating sparse raw image files by optimizing
|
|
away excess lseek() system calls.
|
|
|
|
Fix support of large (> 2GB) files when used as a filesystem in
|
|
mke2fs, tune2fs, debugfs, and findsuper.
|
|
|
|
Debugfs's stat and icheck commands now properly deals with large (>
|
|
2GB) files.
|
|
|
|
Debugfs's set_super_value command now prints out the list of valid
|
|
superblock fields which can be set using the command.
|
|
|
|
Debugfs's rm and kill_file command now updates the superblock free block
|
|
and inode counts, thus keeping the filesystem consistent.
|
|
|
|
Debugfs's lsdel command now takes an optional argument which allows
|
|
the user to only see the most recently deleted files.
|
|
|
|
A new command (undel) was added to debugfs which automates
|
|
undeleting a deleted inode and linking it back to a directory.
|
|
|
|
Debugfs's ls command now takes a new option, -d, which lists
|
|
deleted directory entries.
|
|
|
|
Debugfs's testb, freeb, setb, and find_free_block commands now take an
|
|
optional count argument.
|
|
|
|
Add support for a new ext2 file attribute, EXT2_NOTAIL_FL, which will
|
|
be used to signal that a particular inode should not be eligible for
|
|
tail-merging --- this is needed for programs like LILO.
|
|
|
|
The findsuper (an unreleased, uninstalled utility program) has been
|
|
improved to add extra validity checks and to add a progress meter.
|
|
(It is still an unsupported program; the officially supported way to
|
|
recover from a trashed partition table is to use gpart; findsuper is
|
|
for wizards only. :-)
|
|
|
|
Debugfs was fixed to compile with "configure --disable-swapfs".
|
|
|
|
Cleaned up various manual pages. (Addresses Debian bug #119624, #120171)
|
|
|
|
Added new translation file for Turkish.
|
|
|
|
Programmer's notes:
|
|
-------------------
|
|
|
|
Fix general gcc -Wall complaints.
|
|
|
|
E2fsprogs (mostly) works with the dietlibc.
|
|
|
|
The programming texinfo file has been expanded to include description
|
|
of additional libext2fs functions. (Still not compeltely done, but a
|
|
lot of the more important functions have been documented.)
|
|
|
|
Added a umask structure to struct_ext2_filsys, which currently only
|
|
modifies the behaviour of ext2fs_mkdir(), but if we add any file
|
|
creation functions to libext2fs, we should also make sure they respect
|
|
the umask setting.
|
|
|
|
The build-rpm script was fixed to be a bit more safe.
|
|
|
|
The tests' Makefile now has a way of automating test case creation
|
|
for e2fsck, using "make testnew".
|
|
|
|
Created a new function, ext2fs_dir_iterate2 which passes more
|
|
information to the callback function (identical to the one used by
|
|
ext2fs_dblist_dir_iterate). The directory iterator functions take a
|
|
new flag, DIRENT_FLAG_INCLUDE_REMOVED, which will return deleted
|
|
directory entries. If the directory entry is deleted, the callback
|
|
function will be called with the entry paraemter set to
|
|
DIRENT_DELETED_FILE.
|
|
|
|
Added new functions, ext2fs_inode_alloc_stats and
|
|
ext2fs_block_alloc_stats, which takes updates block/inode allocation
|
|
statistics in the bitmaps, block group descriptors, and superblock
|
|
when inodes or blocks are allocated or deallocated.
|
|
|
|
|
|
E2fsprogs 1.25 (September 20, 2001)
|
|
===================================
|
|
|
|
This is primarily a bug-fix release; no new features were added, but
|
|
there are a number of embarassing bug fixes and cleanups applied.
|
|
|
|
Fix a bug mke2fs which causes stack garbage to be written to disk when
|
|
zapping disk sectors. (This bug could cause mke2fs to core dump for
|
|
some kernels, I suspect with security enhancement patches.)
|
|
|
|
Remove unneeded #include of <linux/config.h> which was breaking
|
|
building e2fsprogs on the Hurd. (Addresses Debian bug #112414.)
|
|
|
|
Updated tune2fs man page to reflect the fact that adding or removing a
|
|
journal doesn't require running e2fsck.
|
|
|
|
Remove use of AC_REQUIRE from autoconf which had been used to prevent
|
|
AC_CANONICAL_HOST from being called twice; unfortunately this causes
|
|
recent autoconf to bomb out since they don't allow AC_REQUIRE to be
|
|
used outside of autoconf macros. Fortunately, it doesn't seem to be
|
|
necessary any more, anyway.
|
|
|
|
E2fsck will now not fall back to an alternate superblock if the user
|
|
specifies the superblock location explicitly on the command-line.
|
|
This allows easier recovery from a situation where the primary
|
|
superblock and block groups are slightly corrupted, but the backup
|
|
superblocks are completely broken.
|
|
|
|
Fix problem which caused compile_et and mk_cmds to blow up if
|
|
e2fsprogs was in a directory with a pathname that contained spaces.
|
|
|
|
We are now more paranoid about checking the entry in /etc/mtab to make
|
|
sure the filesystem is really mounted, since some broken distributions
|
|
(read: Slackware) don't initialize /etc/mtab before checking non-root
|
|
filesystems. (Slackware also doesn't check the root filesystem
|
|
separately, and reboot if the root filesystem had changes applied to
|
|
it, which is dangerous and broken, but there's nothing I can do about
|
|
that.)
|
|
|
|
Make UUID library C++ friendly by adding appropriate extern "C"
|
|
declarations and using const in the function declarations.
|
|
|
|
Fix up the com_err texinfo file so that it can product a valid info
|
|
file (previously, it could only be used to generate paper
|
|
documentation using texinfo.tex).
|
|
|
|
|
|
E2fsprogs 1.24a (September 2, 2001)
|
|
===================================
|
|
|
|
Fix brown-paper bug in mke2fs which caused it to segfault when
|
|
printing the version string.
|
|
|
|
|
|
E2fsprogs 1.24 (August 30, 2001)
|
|
================================
|
|
|
|
Revert the BLKGETSIZE64 support, since for some distributions, this
|
|
ioctl has been used by an unofficial kernel patch to update the last
|
|
sector on the disk, and this was causing disk corruption problems as a
|
|
result.
|
|
|
|
Mke2fs is now more careful about zapping swap space signatures and
|
|
other filesystem/raid superblock magic values so that programs like
|
|
mount who try to use hueristics to determine the filesystem type of a
|
|
partition are less likely to be confused.
|
|
|
|
E2fsck will no longer complain if the the mode of EXT2_RESIZE_INO is a
|
|
regular file (since Andreas Dilger's on-line resizing tools will set
|
|
its mode bits).
|
|
|
|
Fixed some minor texinfo, man pages nits for spelling errors,
|
|
texinfo warnings, etc. (Addresses Debian bug #110621.)
|
|
|
|
E2fsprogs program no longer print the filesystem version number
|
|
(i.e. 0.5b), since it only confuses people and doesn't serve any real
|
|
purpose.
|
|
|
|
E2fsck will once again compile under libc5, since it will supply its
|
|
own version of strnlen if necesssary.
|
|
|
|
mke2fs and tune2fs will allow the use of UUID= or LABEL= specifiers
|
|
when specifying the external journal device. tune2fs will also search
|
|
devices looking for the externla journal debice when removing.
|
|
|
|
E2fsprogs 1.23 (August 15, 2001)
|
|
================================
|
|
|
|
Add initial support for extended attributes (EA); e2fsck will
|
|
correctly handle a filesystem with EA's and check the EA blocks for
|
|
corruptions.
|
|
|
|
E2fsck's symlink sanity checking has been cleaned up. It now checks
|
|
the i_size value of fast symlinks, and checks for immutable flags
|
|
being set of symlinks, etc.
|
|
|
|
E2fsck now offers to clear inodes which are special files that have a
|
|
non-zero i_blocks or i_size field. (The i_size field check was in the
|
|
previous version of the code, but due to a bug it didn't offer to
|
|
clear the inode unless i_size and i_size_high were both non-zero.)
|
|
|
|
E2image can now create "raw" image files, which only contain the
|
|
filesystem metadata placed in a spare file so that e2fsck, dumpe2fs,
|
|
debugfs, etc., can be run directly on the raw image file.
|
|
|
|
Add support for the 64-bit block device patches.
|
|
|
|
Fixed bugs in creating external journals with a 1k blocksize.
|
|
|
|
Add initial support for external journals (so long as the external
|
|
journal only supports a single filesystem) in e2fsck.
|
|
|
|
Remove requirement for needing to run fsck on a filesystem after
|
|
removing a journal (either internal or external).
|
|
|
|
The man pages now document how to create and manage external journals.
|
|
|
|
Speed up the check of an ext3 filesystems by avoiding a needless flush
|
|
of all of the superblock and block group descriptors.
|
|
|
|
Speed up creating an internal journal using tune2fs in the case where
|
|
the filesystem has a lot blocks already allocated.
|
|
|
|
Tune2fs has been fixed to make sure that only error messages go to
|
|
stderr, and normal message go to stdout. (Addresses Debian bug #108555)
|
|
|
|
Fixed a minor bug in mke2fs; if -O none is passed to mke2fs, it will
|
|
now not set the sparse_super feature. (Addresses Debian bug #108165)
|
|
|
|
Add support in fsck for the filesystem type "auto".
|
|
|
|
Fsck -A will not try to interpret device names for filesystems which
|
|
have a pass number is 0. (Addresses Debian bug #106696).
|
|
|
|
Fsck prints a warning message if now valid filesystems are passed to
|
|
it. (Addresses Debian Bug #107458.)
|
|
|
|
E2fsck now gives an explicit warning if there filesystem still has
|
|
errors at the end of the run. (Addresses Debian bug #104502)
|
|
|
|
E2fsck will set the EXT2_ERROR_FS flag if the journal superblock
|
|
reflects an error. E2fsck will also not run the orphan list if the
|
|
filesystem contains errors, since the orphan list might be corrupted.
|
|
|
|
E2fsck now prints the number of large files when given the -v option.
|
|
|
|
Fixed minor memory leaks in e2fsck.
|
|
|
|
Some minor man pages updates. (Addresses Debian bug #30833, #108174)
|
|
|
|
|
|
E2fsprogs 1.22 (June 22, 2001)
|
|
==============================
|
|
|
|
Fixed a bug in e2fsck's handling of orphan inodes which are special
|
|
files (i.e., block/character device files, named FIFO's, etc.).
|
|
|
|
Fixed a bug accidentally introduced in e2fsprogs 1.21 which caused
|
|
tune2fs to fail at adding a journal to a mounted filesystem.
|
|
|
|
Fixed a few big-endian bugs in e2fsprogs
|
|
* The directory block functions were accidentally reporting
|
|
some directories as corrupted when they weren't.
|
|
* If e2fsprogs is compiled --disable-swapfs, the C language
|
|
equivalents weren't being included for big-endian platforms.
|
|
(Fixes Debian bug #101686).
|
|
|
|
Fixed a Hurd compilation problem. (Addresses Debian bug #101361)
|
|
|
|
Programmer's notes:
|
|
-------------------
|
|
|
|
Use platform independent method of defining the BLKFLSBUF and FDFLUSH
|
|
ioctls, and allow them to be defined for non-i386 platforms.
|
|
|
|
The uuid.h header file is now protected against multiple inclusions.
|
|
|
|
E2fsprogs is now being developed using BitKeeper. Changed the test
|
|
scripts to deal with BK's stripping CR characgters from text files,
|
|
and changed the top-level Makefile.in to avoid including BitKeeper
|
|
files when generating the source tarball.
|
|
|
|
|
|
E2fsprogs 1.21 (June 15, 2001)
|
|
==============================
|
|
|
|
Added new configure flags which allow a subset e2fsprogs to be built;
|
|
this is most useful for boot floopies, since the resulting shared
|
|
libraries and programs are slimmed down by removing features that
|
|
aren't necessary for a boot floppy. The new flags that were added
|
|
are: --disable-swapfs, which removes support for byte swapping old
|
|
legacy PPC/68k filesystems, --disable-debugfs, which removes support
|
|
for debugfs from the libext2fs library, --disable-imager, which
|
|
removes support for the e2image program, and --disable-resizer, which
|
|
removes support for resize2fs.
|
|
|
|
E2fsck now prints the number of mounts or days elapsed since the last
|
|
check when e2fsck is forced to check an otherwise clean filesystem.
|
|
|
|
Tune2fs now prints an informative message about how often a filesystem
|
|
will be checked when adding a journal to the filesystem, to remind the
|
|
user that he/she may want to adjust those parameters using tune2fs
|
|
-c/-i.
|
|
|
|
Worked around hurd brain-damage which causes e2fsck to sometimes
|
|
believe a filesystem is the root filesystem based on device numbers
|
|
(since Hurd doesn't have dev_t's, which is arguably a POSIX.1
|
|
violation).
|
|
|
|
Fixed a bug introduced in 1.20 which caused e2fsck to abort with an
|
|
erroneous error with the -F option was specified.
|
|
|
|
Fixed a ext3 recovery bug in the revoke handling; synchronized with
|
|
ext3 0.7a.
|
|
|
|
Fixed two bugs in e2fsck's handling of dup block handling, dealing
|
|
with relatively uncommon edge cases: a directory with an indirect
|
|
block which is claimed by another file, and when the last inode in the
|
|
filesystem has blocks claimed by another file.
|
|
|
|
E2fsck now checks to see if the i_size field of a fast symlink is too
|
|
big, and offers to clear the symlink if so.
|
|
|
|
E2fsck now checks to see if i_size_high of special files is non-zero,
|
|
and offers to clear i_size_high.
|
|
|
|
Fix e2fsck's handling of incompatible journal flags so that the user
|
|
has chance to abort, and then has the option to clear out the journal
|
|
entirely. (Addresses Debian bug #98527.)
|
|
|
|
Fixed a bug in fsck which could cause it to core dump if a mix of
|
|
standard and non-standard device names are used in /etc/fstab.
|
|
(Debian bug #100559)
|
|
|
|
Fixed a bug in debugfs which caused read errors when copying a file to
|
|
not be noticed.
|
|
|
|
The debugfs set_super_value command can now modify the s_lastcheck field.
|
|
|
|
Fixed a bug in lsattr and chattr which was accidentally introduced in
|
|
1.20 to support > 2GB files; both lsattr and chattr wasn't reading
|
|
directories correctly because the change modified the layout of struct
|
|
dirent to be incompatible with the libe2p shared library.
|
|
|
|
Cleaned up the mke2fs manual page and included a discussion about why
|
|
it's good to periodically check the filesystem even when journaling is
|
|
enabled.
|
|
|
|
Programmer's notes:
|
|
-------------------
|
|
|
|
Fix general gcc -Wall complaints.
|
|
|
|
The types needed by the ext2 header files are now provided by
|
|
lib/ext2fs/ext2_types.h, instead of include/asm/types.h.
|
|
|
|
Integers are now preferred to longs when trying to find a 32-bit type
|
|
in ext2_types.h. Also, if linux/types.h has already been defined,
|
|
don't try to redefine the types.
|
|
|
|
Fixed make depend script so that it automatically corrects the
|
|
pathname cleanups performed by make -M, so I don't have to fix them up
|
|
by hand.
|
|
|
|
Fixed the d_loaddump test case to be more robust, and not depend on
|
|
bash'isms.
|
|
|
|
Removed debugfs's dependence on pread(), which was accidentally
|
|
intrudced in e2fsprogs 1.20
|
|
|
|
Fixed a performance bug in the libext2fs's icount routine; the size
|
|
estimate of the icount array was incorrectly being calculated.
|
|
|
|
Removed use of the badblocks compatibility functions in the e2fsprogs
|
|
programs.
|
|
|
|
Added paranoia code which protects against strange cases where /etc
|
|
isn't on the root filesystem, or if /etc/mtab doesn't exist.
|
|
|
|
The header file ext2_types.h is now installed.
|
|
|
|
Autoconf is used to determine when we are on big-endian machines,
|
|
instead of doing run-time tests, to save a few bytes of code.
|
|
|
|
The ext2fs_mark_generic_bitmap and ext2fs_unmark_generic_bitmap
|
|
functions are no longer inline functions, which saves space and
|
|
doesn't really cost any real performance.
|
|
|
|
The ext2fs library no longer depends on the e2p library. (What need
|
|
there was of it --- namely, fsetflags, was coded in-line).
|
|
|
|
Fixed the makefile so that lib/ext2fs/ext2_types.h is generated even
|
|
when the user is stupid and tries compiling the package using "make
|
|
install" as root.
|
|
|
|
Miscellaneous code cleanups:
|
|
* Added missing files from Makefile.in's SRCS file, so that
|
|
their dependencies would be properly calculated.
|
|
* Removed redundant code
|
|
* Fixed comments in code
|
|
* Removed no-longer unneeded argsused #pragma.
|
|
|
|
|
|
E2fsprogs 1.20 (May 20, 2001)
|
|
=============================
|
|
|
|
Add support for replaying the ext3 journal purely in user mode,
|
|
including handling the orphaned inode list. Used code contributed by
|
|
Andreas Dilger, with bug fixes and the orphaned inode handling done
|
|
by Theodore Ts'o.
|
|
|
|
The mke2fs and tune2fs programs can create or modify a filesystem to
|
|
include an ext3 journal. Tune2fs also can be used to remove an ext3
|
|
journal from a filesystem.
|
|
|
|
E2fsck will now check for the existence of a linked list of orphan
|
|
inodes in the superblock, and clear those inodes before starting the
|
|
rest of the filesystem check (but after the journal playback).
|
|
|
|
E2fsck now validates the file descriptor passed to the -C option,
|
|
which saves against the completion bar getting written to an
|
|
unexpected location, such as the disk being checked. (Debian
|
|
bug/wishlist #55220)
|
|
|
|
E2fsck will now bump the filesystem revision number from zero to one
|
|
if any of the compatibility bits are set.
|
|
|
|
Fixed a bug where a badly corrupted directory on a big endian system
|
|
could cause e2fsck to die with a bus error. The
|
|
ext2fs_read_dir_block() and ext2fs_process_dir_block() functions in
|
|
the ext2 library now does alignment sanity checks on the rec_len field
|
|
of the directory entry before using it.
|
|
|
|
The ext2 library has been enhanced to make tune2fs safe to run on
|
|
mounted filesystems. (Users could usually get away with using tune2fs
|
|
on mounted filesystems before, but with the advent of ext3 and
|
|
journaling, it became important to make tune2fs was *really* safe for
|
|
use even when the filesystem being modified is mounted.) E2label is
|
|
now implemented by tune2fs using an argv[0] dispatch, so that e2label
|
|
is also now safe for use on mounted filesystems.
|
|
|
|
Added a new program, e2image, which creates a backup of critical ext2
|
|
filesystem data structures. The generated image file can be examined
|
|
using dumpe2fs and debugfs. In the future, e2fsck will be able to use
|
|
the image file to help recover very badly damaged filesystems.
|
|
|
|
Fixed a number of LFS bugs in e2fsck; very, very large (> 2**42) files
|
|
no longer cause e2fsck to bomb out. Also treat files > 2GB as being
|
|
large file when deciding whether or not the filesystem has large files.
|
|
|
|
Fixed lsattr and chattr so that they work correctly on large files.
|
|
(Fixes Debian bug #72690.)
|
|
|
|
Removed limitation in get_device_size() which imposed a one terrabyte
|
|
filesystem limitation. (Most 2.2 kernels still have a signed int
|
|
problem which cause 1 TB block device limitation. Fortunately, the
|
|
kernel patches to fix this are much easier than fixing the 2TB
|
|
limitation in the kernel. :-)
|
|
|
|
A max_mount_count of zero is now treated as if no mount count were
|
|
set. (Previously, no mount count was indicated by using -1, and a
|
|
mount count of zero caused e2fsck to always be run.)
|
|
|
|
Mke2fs supports two new filesystem types largefile and largefile4.
|
|
|
|
Mke2fs now adds some randomness in s_max_mount_count so that multiple
|
|
filesystems won't be all checked at the same time under normal
|
|
operations.
|
|
|
|
Fixed bug in the progress bar printing code which could cause e2fsck
|
|
to core dump on an illegal filesystem.
|
|
|
|
Fixed bug in fsck which could allow more than one instance of e2fsck
|
|
to be printing a progress bar. (Debian bug #65267)
|
|
|
|
Fsck using a UUID or a LABEL specifier will work even if devfs is
|
|
compiled into the kernel and not mounted. If the pathnames in
|
|
/proc/partitions are incorrect, fsck will search /dev for the correct
|
|
device (using the new ext2fs_find_block_device library function).
|
|
Fsck now also checks the RAID devices first so that they are properly
|
|
found when they are in use. Support has also been added to support
|
|
additional IDE disks and the DAC 960 device names. (Debian bug #94159)
|
|
|
|
Fixed a bug in fsck which caused it not deal properly with 16
|
|
byte long filesystem labels.
|
|
|
|
Fsck's -t option has been made a lot more flexible. The semantics for
|
|
what happens if a comma-separated list to fsck has been regularized,
|
|
and it is now possible to filter what filesystems will get checked
|
|
based what is in the filesystem's fstab entry's option field. (Debian
|
|
bug #89483.)
|
|
|
|
The dumpe2fs program can now print out the group description
|
|
information in hex, and also prints the location of the superblock and
|
|
block group descriptor for those block groups that have them.
|
|
|
|
Mke2fs now clears the ext2 superblock before it starts creating a
|
|
filesystem, so that the superblock magic number is only written if the
|
|
filesystem creation process successfully completes.
|
|
|
|
The debugfs program's stat command now pretty-prints the blocks used
|
|
by an inode so that it's more compact and informative.
|
|
|
|
The debugfs stats command now uses the same libe2p code (which is used
|
|
by dumpe2fs) to print the superblock header information. This is more
|
|
complete, and it avoids a bit of code duplication.
|
|
|
|
Added a new debugfs command, set_super_value (ssv) which allows the
|
|
user to set arbitrary superblock fields.
|
|
|
|
Debugfs was extended to support inode numbers in hex (by prefixing
|
|
them with 0x), and so that modify_inode can set the inode generation
|
|
number. Also, there is now a new function command called logdump
|
|
which will dump an ext3 journal.
|
|
|
|
Fixed a bug in debugfs so that quitting out of the pager doesn't kill
|
|
debugfs.
|
|
|
|
Debugfs's dump command now stops immediately upon reporting a disk
|
|
read error. (Fixed a bug in ext2fs_file_read library routine which
|
|
caused debugfs not to stop.) (Debian bug #79163)
|
|
|
|
On systems with /proc/mounts (mainly Linux systems), /proc/mounts is
|
|
checked before /etc/mtab is used, since /proc/mounts is more likely to
|
|
be accurate.
|
|
|
|
Added portability fixes for Solaris and Linux/ia64.
|
|
|
|
Various manual pages were clarified and cleaned up. (Fixed debian
|
|
bugs #63442, #67446, and #87216)
|
|
|
|
|
|
Programmer's notes:
|
|
-------------------
|
|
|
|
The e2fsck message printer now supports %Iu and %Ig, which will print
|
|
out the inode's user and group owners, respectively.
|
|
|
|
E2fsprogs now includes its own version of include/linux/ext2_fs.h, so
|
|
that no longer dependent on the system having the correct version of
|
|
the kernel header files.
|
|
|
|
Added a new function to libext2, ext2fs_find_block_device(), which
|
|
searches the system (i.e., /dev, /devfs, /devices) for a pathname to a
|
|
device given its device number.
|
|
|
|
Added a new function to libext2, ext2fs_sync_device, which centralizes
|
|
all of the places which might try to use the BLKFLSBUF or FDFLUSH
|
|
ioctls (and usually failing to define them since the system header
|
|
files don't usually do this for us, and we're trying to avoid usage of
|
|
kernel include files now).
|
|
|
|
Added new utility programs in tests/progs: random_exercise and
|
|
hold_inode. They aren't built by default; they're useful for
|
|
exercising ext3 filesystem code.
|
|
|
|
Added a new ext2 filesystem flag, EXT2_FLAG_SUPER_ONLY, which causes
|
|
the filesystem close functions to only update the superblock, and to
|
|
not touch the block group descriptors. Needed by tune2fs when
|
|
modifying a mounted filesystem.
|
|
|
|
Got rid of struct ext2fs_sb and replaced it with the standard struct
|
|
ext2_super_block from include/linux/ext2_fs.h. Note: this may break
|
|
source (but not binary) compatibility of some users of the ext2
|
|
library. Those applications should just simply do a global search and
|
|
replace of struct ext2fs_sb with struct ext2_super_block, and include
|
|
the new header file <ext2fs/ext2_fs.h> which defines it.
|
|
|
|
The ino_t type has been renamed ext2_ino_t to protect applications
|
|
that attempt to compile -D_FILE_OFFSET_BITS=64, since this
|
|
inexplicably changes ino_t(!?). So we use ext2_ino_t to avoid an
|
|
unexpected ABI change.
|
|
|
|
The Makefiles have been reworked so that "make check" can be run from
|
|
the top-level Makefile.
|
|
|
|
Fix general gcc -Wall complaints and removed dead code.
|
|
|
|
Remove use of NOARGS, because we assume everyone does ANSI C these
|
|
days.
|
|
|
|
Added build-rpm script from sct.
|
|
|
|
New functions ext2fs_image_{inode,super,bitmap}_{read,write} added
|
|
to support e2image.
|
|
|
|
New function ext2fs_flush_icache which must be called if the
|
|
application program modifies the inode table blocks without going
|
|
through ext2fs_write_inode() interface.
|
|
|
|
New ext2fs_check_mount_point() function, which will return the mount
|
|
point of a device if mounted.
|
|
|
|
The io_channel abstraction now has an optional interface,
|
|
io_channel_write_range, which allows specific byte ranges to be
|
|
written.
|
|
|
|
The unix_io IO channel now supports write-through caching, so that
|
|
journal creation is more efficient.
|
|
|
|
Added x86 assembly language routines to support byte swapping, to
|
|
reduce executable size.
|
|
|
|
Fixed bug in the utility program subst so that it's possible to
|
|
replace a substitution variable with a zero-length string.
|
|
|
|
Fixed numbering e2fsck pass1 problem numbers; an extra zero had
|
|
slipped into some of the problem number.
|
|
|
|
E2fsprogs 1.19 (July 13, 2000)
|
|
==============================
|
|
|
|
Release the resize2fs program since the timeout before it could
|
|
be released under the GPL has finally expired.
|
|
|
|
Add experimental support needed for the ext2 compression patches.
|
|
This requires compiling e2fsprogs with the --enable-compression flag
|
|
to the configure script.
|
|
|
|
Added ext3 journalling support. E2fsck will run the journal (if
|
|
necessary) by temporarily mounting the filesystem. /sbin/fsck.ext3 is
|
|
installed as a symlink to e2fsck. Fsck has been taught about ext3,
|
|
and treats it the same as ext2 in terms of the progress bar logic.
|
|
Dumpe2fs will display the superblock journaling information if the
|
|
filesystem has a journal. The ext2 library will now permit opening an
|
|
ext3 filesystem with the recovery flag set. This is necessary for
|
|
on-line dump's to work correctly, but there may be issues with this
|
|
working well since ext3 is much less agressive about syncing blocks to
|
|
the filesystem, since they're safe on the journal.
|
|
|
|
Tune2fs and e2fsck have been changed to allow the mount_count check to
|
|
be disabled by setting max_mount_count to -1. (This was already
|
|
supported by the kernel.)
|
|
|
|
Create a symbolic link for fsck.ext3, since the e2fsprogs utilities
|
|
are used for ext3 as well.
|
|
|
|
Added internationalization support for e2fsprogs; must be enabled
|
|
by passing --enable-nls to configure.
|
|
|
|
Always use the provided ext2fs header files to insulate ourselves from
|
|
kernel version changes. Which include files are used by e2fsprogs
|
|
have also been cleaned up to improve portability.
|
|
|
|
Limit the number of times that e2fsck updates the progress bar so that
|
|
people who are booting using a 9600 baud console don't get swampped by
|
|
too many updates.
|
|
|
|
Improved the loop detection algorithm in e2sck's pass #3 so that it is
|
|
much, much faster for large filesystems with a large number of
|
|
directories.
|
|
|
|
The memory footprint for e2fsck is now slightly smaller than before.
|
|
|
|
E2fsck now checks if special devices have a non-zero size, and offers
|
|
to clear the size field if it finds such an inode.
|
|
|
|
E2fsck now checks if special devices have the append-only flag set,
|
|
and offers to clear the inode.
|
|
|
|
E2fsck now properly handles some "should never fail" cases during a
|
|
bitmap copy in pass5.
|
|
|
|
E2fsck now properly prints control characters in filenames as ^A .. ^Z.
|
|
|
|
E2fsck now calculates the correct location of the backup superblock in
|
|
the case of filesystem blocksizes > 1k.
|
|
|
|
Fixed a bug in e2fsck's calculation of the number of inodes_per_block
|
|
which normally didn't cause problems under most filesystem parameters,
|
|
but could cause a valid superblock to be rejected in extreme cases.
|
|
Other checks for validating superblock values were made more
|
|
stringent.
|
|
|
|
Added non-destructive write testing to the badblocks program, courtesy
|
|
of David Beattie. The badblocks also now has an option to input the
|
|
current set of bad blocks, so that known bad blocks are skipped to
|
|
speed up the badblocks test. There is also a persistent rescan
|
|
feature which causes badblocks to run until it has completed some
|
|
number of passes without discovering any new bad blocks.
|
|
|
|
Badblocks now checks to see if the device is mounted and refuses to do
|
|
the tests involving writing to the device if it is mounted. Also,
|
|
badblocks now allows the number of blocks to be checked to be
|
|
defaulted to the size of the partition.
|
|
|
|
Fixed a bug in fsck which didn't allow non-root users to be able to
|
|
check filesystems if there were any LABEL= or UUID= entries in
|
|
/etc/fstab.
|
|
|
|
The Hurd doesn't support the filetype filesystem feature. The mke2fs
|
|
program now makes sure that for the Hurd, the filestype feature is
|
|
turned off. E2fsck will check to see if the filetype feature is
|
|
turned on for Hurd filesystems, and offer to turn off the feature.
|
|
|
|
Mke2fs now has a safety check to make sure the number of blocks do not
|
|
exceed 32 bits even on a 64 bit platform.
|
|
|
|
Really fixed a bug in fsck to allow "fsck -As" to run interactive
|
|
fsck's. (For those people who like to do interactive fsck's in the
|
|
/etc/rc scripts!?!)
|
|
|
|
Debugfs has a few new features: the rdump command, which will do a
|
|
recursive dump of a directory and all of its contents, and the lcd
|
|
command which does a local chdir (much like the ftp command of the
|
|
same name). In addition, the debugfs program and the open_filesystem
|
|
command now takes three new options: -b and -s, which allows the
|
|
blocksize and superblock location to be specified, and the -c option
|
|
which is used in catastrophic situations where the block group
|
|
descriptors are corrupt. If the -c option is specified, debugfs will
|
|
skip trying to read in the block and inode bitmaps.
|
|
|
|
Debufs's lsdel command was fixed to handle bad blocks in the inode
|
|
table.
|
|
|
|
A Y2K bug in debugfs's "ls -l" handling was fixed by switching to use
|
|
4 digit years.
|
|
|
|
General improvements in error messages
|
|
|
|
- Mke2fs prints a sane error message if the partition size is zero
|
|
(usually because the partition table wasn't reread by the
|
|
kernel due to the partition being busy), instead of "invalid
|
|
argument passed to ext2 library while initializing superblock".
|
|
|
|
- Fsck now prints more self-explanatory message if an invalid UUID=
|
|
or LABEL= specification is passed to it.
|
|
|
|
UUID library changed to use the LGPL.
|
|
|
|
Fixed a bug in the UUID library where very rapid calls to the
|
|
time-based UUID generator could cause duplicate UUID's to be returned.
|
|
This was not a problem for e2fsprogs, but it could be a problem for
|
|
other users of the library.
|
|
|
|
Make the UUID library more robust in the face of missing or an
|
|
improper /dev/urandom or /dev/random files.
|
|
|
|
Added some random portability fixes for Solaris.
|
|
|
|
Some minor man page updates.
|
|
|
|
Fixed a memory leak in the ss library.
|
|
|
|
|
|
Programmer's notes:
|
|
-------------------
|
|
|
|
We now try to use lseek64 and open64 from the LFS if possible.
|
|
|
|
The 3rd parameter in e2p's print_flags is now a flags word, instead of
|
|
a boolean option.
|
|
|
|
The mark and unmark bitmap functions now return the previous state of
|
|
the bit that was being changed, which is useful for some speed
|
|
optimizations.
|
|
|
|
The following functions have been added to enhance the badblocks list
|
|
handling in libext2fs: ext2fs_write_bb_FILE, ext2fs_read_bb_FILE2, and
|
|
ext2fs_badblocks_equal.
|
|
|
|
The ext2 header files now have the latest journalling fields to the
|
|
superblock.
|
|
|
|
The ext2fs_mkdir function in libext2fs now properly backs out of error
|
|
conditions robustly.
|
|
|
|
Cleaned up makefiles:
|
|
- to cleanly compile with the -j flag.
|
|
- so distclean removes all generated files.
|
|
- so in case of an error while installing header files, the make aborts.
|
|
|
|
Fix test_script so that it works correctly when compiling in the
|
|
source directory.
|
|
|
|
The random UUID generation routine has been made slightly better in
|
|
the case where /dev/random doesn't exist. (Use of randomly-based UUID
|
|
is still not recommended if /dev/random doesn't exist, however; it's
|
|
better to use the time/ethernet MAC address UUID in this case.)
|
|
|
|
Clean up the build process so it's more friendly in case of missing
|
|
directories.
|
|
|
|
The ext2fs header file can now be #include'd into C++ programs.
|
|
|
|
The e2p.h header file is now installed.
|
|
|
|
Added workaround to a gawk 3.0.5 bug in lib/ss/mk_cmds.
|
|
|
|
|
|
|
|
E2fsprogs 1.18 (November 10, 1999)
|
|
==================================
|
|
|
|
Fix a core dumping bug in e2fsck if an imagic inode is present or
|
|
(more rarely) if the filesystem is badly corrupted enough that e2fsck
|
|
has to restart pass 1 processing. E2fsck now closes the filesystem
|
|
before freeing a large number of its data structures, so in the case
|
|
of future memory faults, at least the fixed filesystem will be fully
|
|
written out.
|
|
|
|
If a filesystem doesn't support imagic inodes, and e2fsck discovers an
|
|
imagic inode, it will offer to clear the imagic flag.
|
|
|
|
E2fsck will now offer to clear the immutable flag on special files
|
|
(device/socket/fifos) when running it in non-preen mode.
|
|
|
|
E2fsck will now set the filetype when creating /lost+found, and when
|
|
connected orphaned inodes to /lost+found.
|
|
|
|
Debugfs's ncheck and icheck commands now handles the case where there
|
|
are bad blocks in the inode table without bombing out.
|
|
|
|
The badblocks list processing code has been made more efficiently for
|
|
appending a large number of (ordered) badblocks to the badblocks list.
|
|
|
|
Some minor man page updates.
|
|
|
|
Fsck now allows interactive e2fsck's when using fsck -As (not a common
|
|
mode, but some people like to do this in boot scripts for silly reasons).
|
|
|
|
Programmer's notes:
|
|
-------------------
|
|
|
|
The internal e2fsck problem code for PR_2_SPLIT_DOT was fixed to meet
|
|
with the problem code convention.
|
|
|
|
The badblocks list regression test program has been updated to work
|
|
with previously made API name changes.
|
|
|
|
The ext2fs_free() command now uses the new badblocks API to avoid
|
|
using the compatibility layer.
|
|
|
|
Added new regression test cases; the run_e2fsck test script now
|
|
supports the ability for a test case to run a prepratory command
|
|
before running e2fsck.
|
|
|
|
E2fsprogs 1.17 (October 26, 1999)
|
|
=================================
|
|
|
|
Fixed nasty typo in fsck which caused parallelized fsck's to go into an
|
|
infinite loop.
|
|
|
|
Fixed a bug in fsck where it used strncmp to compare a binary UUID,
|
|
thus potentially causing problems if a binary UUID contained a NULL
|
|
character.
|
|
|
|
E2fsck now uses stricter checks for directory entries in pass 2:
|
|
zero-length filenames are not allowed; neither are 8 byte long
|
|
directory entries.
|
|
|
|
The debugfs "dirty" command now clears the filesystem valid bit.
|
|
(Previously this just set the dirty-as-in-needs-writing-out-to-disk
|
|
bit in the in-core superblock image. The new functionality is more
|
|
what the user expects, and is more useful.)
|
|
|
|
Added a debugging hook to test parallel fsck; if the environment
|
|
variable FSCK_FORCE_ALL_PARALLEL, then filesystems on the same drive
|
|
will be checked in parallel when they normally would not be.
|
|
|
|
Programmer's notes:
|
|
-------------------
|
|
|
|
Fixed some #ifdef's for compilation under the Hurd OS.
|
|
|
|
Fixed minor W2K compatibility problems.
|
|
|
|
Fixed some miscellaneous GCC warnings.
|
|
|
|
|
|
E2fsprogs 1.16 (October 22, 1999)
|
|
=================================
|
|
|
|
Fixed a race condition bug in fsck; when printing a progress bar, if
|
|
checking multiple filesystems in parallel, it was possible for fsck to
|
|
send e2fsck a SIGUSR1 signal before e2fsck had installed its signal
|
|
handler, which would cause it to terminate with a signal 10.
|
|
|
|
E2fsck now properly handles filesystems that have the
|
|
INCOMPAT_FILETYPE feature turned on. It can be used to convert a
|
|
filesystem into using or not using FILETYPE feature.
|
|
|
|
E2fsck now properly handles filesystems that have the IMAGIC feature
|
|
turned on (this is used on Linux AFS servers).
|
|
|
|
The mke2fs program now creates filesystems that have the filetype and
|
|
sparse_superblock features enabled by default, unless it is run on a
|
|
pre-2.2 kernel. These features are not supported by a pre-2.2 kernel,
|
|
so there is now a new flag -O which allows the user to specify with
|
|
which features she would like to create the filesystem; "mke2fs -O
|
|
none" will create a filesystsem compatible with 2.0 kernels.
|
|
|
|
The tune2fs program now has a -O option which allows the user to set
|
|
and reset "safe" filesystem features. Currently, the only ones which
|
|
allows to be modified are the filetype and sparse_superblock features.
|
|
Note setting or clearing either feature will require running e2fsck on
|
|
the filesystem afterwards. (n.b. Clearing the sparse_superblock feature
|
|
requires that there is enough free space on the filesystem for the
|
|
extra superblocks which will be created by e2fsck.)
|
|
|
|
Debugfs can now set and print filesystem features in the superblock
|
|
using the "features" command. Dumpe2fs will print out the complete
|
|
set of features when listing the superblock.
|
|
|
|
Dumpe2fs has new options -f (force) and -h (header-only).
|
|
|
|
Fixed a bug in e2fsck which could cause the PROGRAMMING ERROR/bonehead
|
|
message to come up. This could happen when decrementing or
|
|
incrementing a link count could result in an overflow.
|
|
|
|
Fixed a bug in e2fsck where the block count on the lost+found
|
|
directory would not be properly incremented when the directory was
|
|
expanded to the point where an indirect block needed to be allocated.
|
|
|
|
E2fsck now makes some additional sanity checks on the superblock to
|
|
avoid crashing or giving a memory allocation error if some of the
|
|
values in the superblock are unresonable (but the superblock otherwise
|
|
looks valid).
|
|
|
|
Fixed a bug in e2fsck where a very badly corrupted filesystem might
|
|
require two passes to completely fix the filesystem. This happened if
|
|
an inode claimed blocks that was part of the filesystem metadata
|
|
(typically, when garbage was written into an inode table or indirect
|
|
block, since this kind of filesystem corruption normally doesn't
|
|
happen otherwise).
|
|
|
|
On the Alpha, glibc declares st_flags although it isn't actually used;
|
|
the configure script was improved to detect this case so that
|
|
e2fsprogs can avoid using the non-functional stat field.
|
|
|
|
The manual pages were updated to use a more consistent formatting
|
|
style consistent with standard Unix man pages. Mke2fs's man page
|
|
added documentation for a few previously undocumented options.
|
|
|
|
Fixed minor display bugs in tune2fs and mke2fs.
|
|
|
|
Programmer's notes:
|
|
-------------------
|
|
|
|
Improved portability of e2fsprogs to non-Unix systems (in particular, NT).
|
|
|
|
Added features to parse and print feature strings into the e2p library.
|
|
(e2p_feature2string, e2p_string2feature, e2p_edit_feature).
|
|
|
|
ext2fs_mkdir() and ext2fs_new_dir_block() now creates directories
|
|
whose directory entries contain proper filetype information if the
|
|
filesystem supports it.
|
|
|
|
ext2fs_link() now uses the low 3 bits of its flags parameter to pass
|
|
the directory entry filetype information. This is used to set the
|
|
directory entry filetype information if the filesystem supports it.
|
|
|
|
Fixed a bug in ext2fs_expand_dir() where the block count in a
|
|
directory's inode would not be properly incremented when the directory
|
|
was expanded to the point where an indirect block needed to be
|
|
allocated.
|
|
|
|
|
|
E2fsprogs 1.15 (July 18, 1999)
|
|
==============================
|
|
|
|
Add configuration checks so that e2fsprogs will compile cleanly on
|
|
Linux 2.3 kernels that have renamed i_version to i_generation.
|
|
|
|
E2fsck now prints a progress/completion bar (and not just a simple
|
|
spinner) if the -C0 option is requested or if it receives a SIGUSR1
|
|
signal. Fsck will automatically manage the (potentially muliple)
|
|
e2fsck processes to print completion bars if it is given a -C option,
|
|
with the right thing happening if multiple filesystems are being
|
|
checked in parallel.
|
|
|
|
Mke2fs now has better automatic hueristics to determine the filesystem
|
|
parameters to be used for a particular filesystem. Added a new option
|
|
-T which allows the user to specify how the filesystem is to be used,
|
|
which helps mke2fs do a better job selecting the filesystem parameters.
|
|
|
|
Mke2fs now creates revision 1 filesystems by default, and with the
|
|
sparse superblock feature enabled. The sparse superblock feature is
|
|
not understood by Linux 2.0 kernels, so they will only allow read-only
|
|
mounts of filesystems with this sparse superblocks.
|
|
|
|
Fix bug where if /dev/null couldn't be opened (should never happen),
|
|
e2fsck would hang in a tight loop.
|
|
|
|
Make e2fsck handle the case where /lost+found isn't a directory.
|
|
|
|
E2fsck now uses mallinfo if it exists to get accurate statistics about
|
|
its memory usage.
|
|
|
|
Fix bug in e2fsck where it wouldn't check to see if a disconnected
|
|
inode had any problems before connecting it to /lost+found.
|
|
|
|
Add check to e2fsck so it makes sure that total number of inodes in
|
|
the filesystem is a sane number.
|
|
|
|
Fix fencepost error when clearing an the end of the block bitmap which
|
|
caused the last block in the bitmap not to get cleared.
|
|
|
|
Cleaned up a number of messages in e2fsck:
|
|
* The message "Group's #'s copy of the group descriptor..."
|
|
was fixed so that the correct number would be displayed.
|
|
* Added missing space in the "disk write-protected" error messsage
|
|
* Cleaned up the error message printed when a non-interactive
|
|
e2fsck needs to abort a check because the filesystem
|
|
appears to be mounted.
|
|
|
|
Added a new command-line utility, uuidgen, which will create and print
|
|
a UUID.
|
|
|
|
Make debugfs's icheck command more robust by checking to make sure an
|
|
inode has valid blocks before interarting over the inode's blocks.
|
|
|
|
UUID generation now uses a random-based scheme whenever possible to
|
|
prevent potential privacy problems.
|
|
|
|
Man pages for all of the UUID functions in the lirbary were added.
|
|
|
|
Fixed bug in fsck so it won't coredump if a filesystem not in
|
|
/etc/fstab is given to it.
|
|
|
|
Fsck now understands the UUID=xxxx and LABEL=yyyy forms in /etc/fstab
|
|
that most of the other mount utilities understands.
|
|
|
|
Mke2fs will make a filesystem even if it appears mounted if the force
|
|
option is given.
|
|
|
|
Dumpe2fs has new command-line options which allow a filesystem expert
|
|
to specify the superblock and blocksize when opening a filesystem.
|
|
This is mainly useful when examining the remains of a toasted
|
|
filesystem.
|
|
|
|
The badblocks program has been updated to display correctly on disks
|
|
with large block numbers.
|
|
|
|
The badblocks program no longer gives spurious errors when errors
|
|
occur on non-block boundaries, which is common if the blocksize is
|
|
larger than 1k.
|
|
|
|
Mke2fs will sync the disk device every MKE2FS_SYNC block groups if the
|
|
MKE2FS_SYNC environment variable is set. This is to work around a VM
|
|
bug in the 2.0 kernel. I've heard a report that a RAID user was able
|
|
to trigger it even using a 2.2 kernel, but hopefully it will not be
|
|
needed for most Linux 2.2 users.
|
|
|
|
Fixed miscellaneous documentation and man pages.
|
|
|
|
Programmer's notes:
|
|
-------------------
|
|
|
|
Cleaned up functions such as pass1_get_blocks, pass1_read_inode which
|
|
in e2fsck's pass1.c really should have been static.
|
|
|
|
The return value of the uuid_compare() function was changed to make it
|
|
match with the convetions used by strcmp, memcmp, and Paul Leach's
|
|
UUID sample document.
|
|
|
|
The "make depend" process has now been made more automated; it now
|
|
automatically word-wraps the dependencies, and only replaces source
|
|
Makefile.in if there has been a change in the dependencies. Also, a
|
|
top-level "make depend" now recurses through all the subdirectories
|
|
automatically.
|
|
|
|
The Makefile in .../util has been changed so that subst is built using
|
|
the native C compiler during a cross-compilation, since the subst
|
|
program is only used during the build process. Also add an explicit
|
|
rule to build util/subst by cd'ing to the correct directory and
|
|
running Makefile.
|
|
|
|
The man directories are defined in terms mandir, so that the configure
|
|
script can override the location of the manual pages.
|
|
|
|
The config files have been updated to recognize new machine types for
|
|
both the i386 and alpha families.
|
|
|
|
Fsck has been modified so that it will accurately create an
|
|
fsck_instance even when the noexecute flag is set. This allows for
|
|
accurate debugging of the fsck pass structure. Also, when the verbose
|
|
flag is given twice, fsck will print debugging information about when
|
|
fsck is waiting for jobs to finish.
|
|
|
|
|
|
E2fsprogs 1.14 (January 9, 1999)
|
|
================================
|
|
|
|
Fix the fstab parsing code so that it can handle blank lines and
|
|
comment characters. Also, missing pass numbers need to be treated as
|
|
zero.
|
|
|
|
Fixed a bug in e2fsck where under some circumstances (when e2fsck
|
|
needs to restart processing after fixing an egregious inconsistency)
|
|
it would try to access already freed memory.
|
|
|
|
E2fsck now prints non-printable characters in directory entries and
|
|
pathnames using '^' and 'M-' notation.
|
|
|
|
Fixed chattr so that it will ignore symbolic links when doing
|
|
recursive descent traversals. For both chattr and lsattr, no longer
|
|
print the version string unless the -V option is given.
|
|
|
|
Allow the system administrator to directly specify the number of
|
|
inodes desired in the filesystem, for some special cases where this is
|
|
necessary.
|
|
|
|
Fix portability problems so that e2fsprogs can be compiled under Linux
|
|
1.2 systems and Solaris systems.
|
|
|
|
Update the config.guess file with a more recent version that will
|
|
identify newer Linux platforms.
|
|
|
|
Programmer's notes
|
|
------------------
|
|
|
|
Ext2fs_read_inode and ext2fs_write_inode will now return an error if
|
|
an inode number of zero is passed to them.
|
|
|
|
E2fsprogs 1.13 (December 15, 1998)
|
|
==================================
|
|
|
|
Fixed a bug in debugfs where an error messages weren't getting printed
|
|
when the ext2 library routines to read inodes returned errors in the
|
|
stat, cmri and rm commands.
|
|
|
|
Fixed a bug in mke2fs so that if a ridiculous inode ratio parameter is
|
|
provided, it won't create an inode table smaller than the minimum
|
|
number of inodes required for a proper ext2 filesystem.
|
|
|
|
Fsck now parses the /etc/fstab file directly (instead of using
|
|
getmntent()), so that it can distinguish between a missing pass number
|
|
field and pass number field of zero. This caused problems for
|
|
diskless workstations where all of the filesystems in /etc/fstab have
|
|
an explicit pass number of zero, and fsck could not distinguish this
|
|
from a /etc/fstab file with missing pass numbers.
|
|
|
|
E2fsck will create a /lost+found directory if there isn't one in the
|
|
filesystem, since it's safer to create the lost+found directory before
|
|
it's needed.
|
|
|
|
Fixed e2fsck so that it would detect bogus immutable inodes which
|
|
happen to be sockets and FIFO files, and offer to clear them.
|
|
|
|
If a filesystem has multiple reasons why it needs to be checked, and
|
|
one of the reasons is that it is uncleanly mounted, e2fsck will print
|
|
that as the reason why the filesystem is being checked.
|
|
|
|
Cleaned up the output routines of mke2fs so that it doesn't overflow
|
|
an 80 column display when formating really big filesystems.
|
|
|
|
Added a sanity check to e2fsck to make sure that file descriptors 0,
|
|
1, 2 are open before opening the hard disk. This avoids a problem
|
|
where a broken program might exec e2fsck with those file descriptors
|
|
closed, which would cause disastrous results if the kernel returns a
|
|
file descriptor for the block device which is also used by FILE *
|
|
stdout.
|
|
|
|
Fixed up the e2fsck progress reporting functions so that the values
|
|
reliably reach 100% at the completion of all of the e2fsck passes.
|
|
|
|
Fixed minor documentation bugs in man pages and usage messages.
|
|
|
|
Programmer's notes:
|
|
-------------------
|
|
|
|
Fixed a number of lint warnings in the ext2fs library and potential
|
|
portability problems from other OS's header files that might define
|
|
CPP macros for names like "max" and "min".
|
|
|
|
ext2fs_badblocks_list_add() has been made more efficient when it needs
|
|
to grow the bad blocks list.
|
|
|
|
Fixed a bug in e2fsck which caused it to dereference a freed pointer
|
|
just before exiting.
|
|
|
|
Fixed the substition process for generating the mk_cmds and compile_et
|
|
scripts so that they will work outside of the build tree.
|
|
|
|
Add sanity check to e2fsck so that if an internal routine
|
|
(ext2fs_get_dir_info) returns NULL, avoid dereferencing the pointer
|
|
and causing a core dump. This should never happen, but...
|
|
|
|
E2fsprogs 1.12 (July 9, 1998)
|
|
==================================
|
|
|
|
E2fsprogs now works with glibc (at least with the version shipped wtih
|
|
RedHat 5.0). The ext2fs_llseek() function should now work even with
|
|
i386 ELF shared libraries and if llseek() is not present. We also
|
|
explicitly do a configure test to see if (a) llseek is in libc, and
|
|
(b) if llseek is declared in the system header files. (See standard
|
|
complaints about libc developers don't understand the concept of
|
|
compatibility with previous versions of libc.)
|
|
|
|
The ext2fs library now writes out the block group number in each of
|
|
the superblock copies. This makes it easier to automatically
|
|
determine the starting block group of the filesystem when the block
|
|
group information is trashed.
|
|
|
|
Added support for the EXT2_FEATURE_INCOMPAT_FILETYPE feature,
|
|
which means that e2fsprogs will ignore the high 8 bits of the
|
|
directory entry's name_len field, so that it can be used for other
|
|
purposes.
|
|
|
|
Added support for the EXT2_FEATURE_RO_COMPAT_LARGE_FILE feature.
|
|
E2fsprogs will now support filesystems with 64-bit sized files.
|
|
|
|
Added support for the EXT2_FEATURE_COMPAT_DIR_PREALLOC feature.
|
|
|
|
Added new program "e2label", contributed by Andries Brouwer. E2label
|
|
provides an easy-to-use interface to modify the filesystem label.
|
|
|
|
Fixed bug so that lsattr -v works instead of producing a core dump.
|
|
|
|
Fixed a minor bug in mke2fs so that all groups with bad superblock
|
|
backup blocks are printed (not just the first one).
|
|
|
|
Mke2fs will check the size of the device, and if the user specifies a
|
|
filesystem size larger than the apparent size of the device it will
|
|
print a warning message and ask if the user wants to proceed.
|
|
|
|
E2fsck has a new option -C, which sends completion information to the
|
|
specified file descriptor. For the most part, this is intended for
|
|
programs to use, although -C 0 will print a spinning character to the
|
|
stdout device, which may be useful for users who want to see something
|
|
happening while e2fsck goes about its business.
|
|
|
|
Fixed a bug in e2fsck which could cause a core dump when it needs to
|
|
expand the /lost+found directory, and sometimes the bitmaps haven't
|
|
been merged in. Also fixed a related bug where ext2fs_write_dir_block
|
|
was used to write out a non-directory block. (Which would be bad on a
|
|
non-Intel platform with byte swapping going on.)
|
|
|
|
Fixed bug in e2fsck where it would print a "programming error" message
|
|
instead of correctly identifying where a bad block was in used when
|
|
the bad block was in a non-primary superblock or block group
|
|
descriptor. Also fixed a related bug when sparse superblocks are in
|
|
use and there is a bad block where a superblock or block group
|
|
descriptor would have been in a group that doesn't include a
|
|
superblock.
|
|
|
|
Fixed a bug in e2fsck (really in libext2fs's dblist function) where if
|
|
the block group descriptor table is corrupt, it was possible to try to
|
|
allocate a huge array, fail, and then abort e2fsck.
|
|
ext2fs_get_num_dirs() now sanity checks the block group descriptor,
|
|
and subsitutes reasonable values if the descriptors are obviously bogus.
|
|
|
|
If e2fsck finds a device file which has the immutable flag set and the
|
|
i_blocks beyond the normal device number are non-zero, e2fsck will
|
|
offer to remove it, since it's probably caused by garbage in the inode
|
|
table.
|
|
|
|
When opening a filesystem, e2fsck specially checks for the EROFS error
|
|
code, and prints a specific error message to the user which is more
|
|
user friendly.
|
|
|
|
If the filesystem revision is too high, change the e2fsck to print
|
|
that this is either because e2fsck is out of date, or because the
|
|
superblock is corrupt.
|
|
|
|
E2fsck now checks for directories that have duplicate '.' and '..'
|
|
entries, and fixes this corruption.
|
|
|
|
E2fsck no longer forces a sync of the filesystem (with attendant sleep
|
|
calls) at all times. The ext2fs_flush() function now performs a sync
|
|
only if it needed to write data blocks to disk.
|
|
|
|
Fixed a minor bug in e2fsck's pass1b's file cloning function, where
|
|
certain errors would not be properly reported.
|
|
|
|
Updated and expanded a few points in the man pages which users
|
|
complained wheren't explicit enough.
|
|
|
|
Added special case byte-swapping code if compiling on the PowerPC, to
|
|
accomodate the strange big-endian variant of the ext2 filesystem that
|
|
was previously used on the PowerPC port.
|
|
|
|
|
|
Programmer's notes:
|
|
-------------------
|
|
|
|
Removed C++ keywords from the ext2fs libraries so that it could be
|
|
compiled with C++.
|
|
|
|
E2fsck's internal organization has now been massively reorganized so
|
|
that pass*.c don't have any printf statements. Instead, all problems
|
|
are reported through the fix_problem() abstraction interface. E2fsck
|
|
has also been revamped so that it can be called as a library from a
|
|
application.
|
|
|
|
Added new fileio primitives in libext2fs for reading and writing
|
|
files on an unmounted ext2 filesystem. This interface is now used by
|
|
debugfs.
|
|
|
|
Added a new libext2fs function for mapping logical block numbers of
|
|
a file to a physical block number.
|
|
|
|
Added a new libext2fs function, ext2fs_alloc_block(), which allocates
|
|
a block, zeros it, and updates the filesystem accounting records
|
|
appropriately.
|
|
|
|
Added a new libext2fs function, ext2fs_set_bitmap_padding(), which
|
|
sets the padding of the bitmap to be all one's. Used by e2fsck pass 5.
|
|
|
|
The libext2fs functions now use a set of memory allocation wrapper
|
|
functions: ext2fs_get_mem, ext2fs_free_mem, and ext2fs_resize_mem,
|
|
instead of malloc, free, and resize. This makes it easier for us to
|
|
be ported to strange environments where malloc, et. al. aren't
|
|
necessarily available.
|
|
|
|
Change the libext2fs fucntion to return ext2-specific error codes
|
|
(EXT2_DIR_EXISTS and EXT2_DB_NOT_FOUND, for example) instead of using
|
|
and depending on the existence of system error codes (such as EEXIST
|
|
and ENOENT).
|
|
|
|
Renamed io.h to ext2_io.h to avoid collision with other OS's header
|
|
files.
|
|
|
|
Add protection against ext2_io.h and ext2fs.h being included multiple
|
|
times.
|
|
|
|
The types used for memory lengths, etc. have been made more portable.
|
|
In generla, the code has been made 16-bit safe. Added Mark
|
|
Habersack's contributed DOS disk i/o routines.
|
|
|
|
Miscellaneous portability fixes, including not depending on char's
|
|
being signed.
|
|
|
|
The io_channel structure has a new element, app_data, which is
|
|
initialized by the ext2fs routines to contain a copy of the filesystem
|
|
handle.
|
|
|
|
ext2fs_check_directory()'s callback function may now return the error
|
|
EXT2_ET_CALLBACK_NOTHANDLED if it wishes ext2fs_check_directory() to
|
|
really do the checking, despite the presence of the callback function.
|
|
|
|
|
|
E2fsprosg 1.11 (June 17, 1997)
|
|
==============================
|
|
|
|
Fixed e2fsck to detect (previously ignored) conflicts between the
|
|
superblock or block group descriptors and block bitmaps, inode
|
|
bitmaps, and inode tables.
|
|
|
|
Fixed bug in e2fsck so that when the message printed out when a block
|
|
or inode bitmap conflicts with other data, it has the correct group
|
|
number.
|
|
|
|
Fixed bug in e2fsck and mke2fs where the blocksize wasn't being passed
|
|
to badblocks. This meant that not all of the filesystem was being
|
|
tested for bad blocks!
|
|
|
|
Fixed an array boundary overrun case which cropped up in
|
|
ext2fs_badblocks_list_test when a user tried running "mke2fs -c
|
|
-b 4096".
|
|
|
|
Adjusted the number of columns printed by mke2fs when displaying the
|
|
superblock backups to avoid running over 80 columns when making a
|
|
really big filesystem.
|
|
|
|
Fixed up the man pages for e2fsck, debugfs, badblocks, chattr,
|
|
dumpe2fs, fsck, mke2fs, and tune2fs (typos and other minor grammar
|
|
fixes), thanks to some suggestions from Bill Hawes (whawes@star.net).
|
|
|
|
Programmer's notes:
|
|
-------------------
|
|
|
|
Fixed install rule in lib/ss so that ss_err.h is actually getting
|
|
installed.
|
|
|
|
Fixed bug in ext2fs_copy_bitmap; the destination bitmap wasn't getting
|
|
bassed back to the caller.
|
|
|
|
Fixed bug in ext2fs_inode_scan_goto_blockgroup; it had not been
|
|
setting the current inode number (which meant this function wasn't
|
|
working at all).
|
|
|
|
Fixed bug in ext2fs_resize_generic_bitmap; it had not be zeroing all
|
|
blocks in the bitmap when increasing the size of the bitmap.
|
|
|
|
Changed the initial number of blocks allocated by ext2fs_init_dblist()
|
|
to be more realistic.
|
|
|
|
Added a new function ext2fs_allocate_group_table, which sets up the
|
|
group descriptor information (and allocates inode and block bitmaps,
|
|
and inode tables for a particular group). The function was created by
|
|
factoring out code form ext2fs_allocate_tables().
|
|
|
|
Added a new function ext2fs_move_blocks which takes a bitmap of the
|
|
blocks to be moved, and moves them to another location on the
|
|
boardboard.
|
|
|
|
Make the unix_io channel's io_channel_flush implementation calls sync()
|
|
to to flush the kernel buffers to disk.
|
|
|
|
Added a new function ext2fs_dblist_count returns the number of
|
|
directory blocks in dblist.
|
|
|
|
|
|
E2fsprogs 1.10 (April 24, 1997)
|
|
===============================
|
|
|
|
Mke2fs once again defaults to creating revision #0 filesystems, since
|
|
people were complaining about breaking compatibility with 1.2 kernels.
|
|
Warning messages were added to the mke2fs and tune2fs man pages that
|
|
the sparse superblock option isn't supported by most kernels yet (1.2
|
|
and 2.0 both don't support parse superblocks.)
|
|
|
|
Added new flag to mke2fs, -R <raid options>, which allows the user to
|
|
tell mke2fs about the RAID configuration of the filesystem. Currently
|
|
the only supported raid option is "stride" which specifies the width
|
|
of the RAID stripe.
|
|
|
|
Fixed bug in e2fsck where pass1b would bomb out if there were any
|
|
blocks marked bad in the inode table.
|
|
|
|
Fixed rare bug in mke2fs where if the user had a very unlucky number
|
|
of blocks in a filesystem (probability less than .002) the resulting
|
|
filesystem would be corrupt in the last block group.
|
|
|
|
Fixed bug where if e2fsck tried to allocate a block to fix a
|
|
filesystem corruption problem and the filesystem had no free blocks,
|
|
ext2fs_new_block() would loop forever.
|
|
|
|
The configure script now checks explicitly to see if "-static" works,
|
|
since that can't be assumed to be true --- RedHat doesn't install
|
|
libc-static by default.
|
|
|
|
Fixed bug in libext2's block iterator functions where under some
|
|
cirmcustances, file with holes would cause the bcount parameter to the
|
|
callback function to be incorrect. This bug didn't affect any of
|
|
e2fsprogs programs, but it was discovered by Paul Mackerras, the
|
|
author of the PPC boot loader.
|
|
|
|
Removed use of static variables to store the inode cache in libext2fs.
|
|
This caused problems if more than one filesystem was accessed via
|
|
libext2fs (static variables in libraries are generally a bad idea).
|
|
Again, this didn't affect e2fsprogs programs, but it was discovered by
|
|
Paul Mackerras.
|
|
|
|
Fixed minor bugs and version code drift to assure that e2fsprogs 1.10
|
|
will compile cleanly with 1.2.13 kernels (even with a.out shared
|
|
libraries!)
|
|
|
|
Programmer's notes:
|
|
-------------------
|
|
|
|
Added new functions to duplicate an ext2 filesystem handle, and its
|
|
associated substructure. New functions: ext2fs_dup_handle(),
|
|
ext2fs_copy_dblist(), ext2fs_badblocks_copy(), ext2fs_copy_bitmap().
|
|
Other structures, such as the io_channel and the inode_cache, now have
|
|
a ref count so that they only get freed when they are no longer used
|
|
by any filesystem handle. (These functions were added as part of the
|

development effort for an ext2 resizer).

E2fsprogs 1.09 (April 14, 1997)
|
|
===============================
|
|
|
|
Fixed bug in mke2fs (really in lib/ext2fs/initialize.c) which was
|
|
accidentally introduced in the 1.08 release. The overhead calculation
|
|
was accidentally removed, which caused ext2fs_initialize() to not
|
|
notice when the filesystem size needed to be adjusted down because
|
|
there wasn't enough space in the last block group.
|
|
|
|
Fixed bug in version parsing library routine; it was always parsing
|
|
the library version string, instead of using the passed-in string.
|
|
|
|
Clarified chattr man page.
|
|
|
|
E2fsprogs 1.08 (April 10, 1997)
|
|
===============================
|
|
|
|
E2fsck 1.07 was very slow when checking very large filesystems with a
|
|
lot of files that had hard links (i.e., news spools). This was fixed
|
|
by seriously revamping the icount abstraction. Added a formal test
|
|
suite for the icount abstraction.
|
|
|
|
Debugfs now has a "-l" option to the "ls" command, which lists the
|
|
inode number, permissions, owner, group, size, and name of the files
|
|
in the directory.
|
|
|
|
Fix a bug in e2fsck where when a directory had its blocks moved to
|
|
another location during the pass 1b processing, the directory block
|
|
list wasn't updated, so pass 2 wouldn't check (and correct) the
|
|
correct directory block.
|
|
|
|
E2fsck will now treat inodes which contain blocks which are claimed by
|
|
the filesystem metadata by treating them as multiply claimed blocks.
|
|
This way, the data in those blocks can be copied to a new block during
|
|
the pass 1b--1d processing.
|
|
|
|
E2fsck will attempt to determine the correct superblock number and
|
|
display it in the diagnostic and warning messages if possible.
|
|
|
|
Add support for a new (incompatible) feature, "sparse_super". This
|
|
feature reduces the number of blocks which contain copies of backup
|
|
superblocks and block group descriptors. (It is only an incompatible
|
|
feature because of a bug in ext2_free_blocks.) mke2fs and tune2fs now
|
|
support a new -s option; e2fsck will recognize filesystems built with
|
|
this feature turned on.
|
|
|
|
E2fsck now checks the library to make sure is the correct version,
|
|
using new library functions. (This helps to diagnose incorrectly
|
|
installed e2fsprogs distributions.)
|
|
|
|
Dumpe2fs now prints more information; its now prints the the
|
|
filesystem revision number, the filesystem sparse_super feature (if
|
|
present), the block ranges for each block group, and the offset from
|
|
the beginning of the block group.
|
|
|
|
Mke2fs now distributes the inode and block bitmap blok so that the
|
|
won't be concentrated in one or two disks in RAID/striping setups.
|
|
Also, if the user chooses a 2k or 4k block group, mke2fs will try to
|
|
choose the largest blocks per group that be chosen. (For 2k blocks,
|
|
you can have up to 16384 blocks/group; for 4k blocks, you can have up
|
|
to 32768 blocks/group.) Previously mke2fs would not allow
|
|
specification of more than 8192 blocks per group, even if you were
|
|
using a 2k or 4k block group.
|
|
|
|
Programmer's notes:
|
|
-------------------
|
|
|
|
Added a new function ext2fs_create_icount2() which takes a "hint"
|
|
argument. This hint argument presets the icount array with the list
|
|
of inodes which actually need to be in the icount array. This really
|
|
helps to speed up e2fsck.
|
|
|
|
Added a new function ext2fs_icount_validate() which checks the rep
|
|
invariant for the icount structure. This is used mostly for testing.
|
|
|
|
The error mesasage given when a bad inode number is passed to
|
|
test_generic_bitmap to reflect EXT2FS_TEST_ERROR (instead of
|
|
EXT2FS_UNMARK_ERROR).
|
|
|
|
Added a new function ext2fs_set_dir_block which sets the block of a
|
|
dblist entry, given the directory inode and blockcnt.
|
|
|
|
Added a new function ext2fs_get_library_version() which returns the
|
|
current library version, and ext2fs_parse_version_string() which
|
|
returns a version number based on a e2fsprogs version string.
|
|
|
|
The icount functions will return EINVAL if the passed in inode number
|
|
is out of bounds.
|
|
|
|
E2fsprogs 1.07 (March 9, 1997)
|
|
==============================
|
|
|
|
E2fsck is now uses much less memory when checking really large
|
|
filesystems (or rather, filesystems with a large number of inodes).
|
|
Previously a filesystem with 1 million inodes required 4 megabytes of
|
|
memory to store inode count statistics; that storage requirement has
|
|
now been reduced to roughly half a megabyte.
|
|
|
|
E2fsck can now properly deal with bad blocks appearing inside the
|
|
inode table. Instead of trying to relocate the inode table (which
|
|
often failed because there wasn't enough space), the inodes in the bad
|
|
block are marked as in use.
|
|
|
|
E2fsck will automatically try to use the backup superblocks if the
|
|
primary superblocks have a bad magic number or have missing meta-data
|
|
blocks (or meta-data blocks which are out of range).
|
|
|
|
E2fsck's pass 3 has been made more efficient; most noticeable on
|
|
filesystems with a very large number of directories.
|
|
|
|
Completely revamped e2fsck's system of printing problem reports. It
|
|
is now table driven, to make them more easily customizeable and
|
|
extendable. Error messages which can be printed out during preen mode
|
|
are now one line long.
|
|
|
|
Fixed e2fsck's filesystem swapping code so that it won't try to swap
|
|
fast symbolic links or deleted files.
|
|
|
|
Fixed e2fsck core dumping when fixing a filesystem which has no
|
|
directories (not even a root directory).
|
|
|
|
Added a check to e2fsck to make sure that the length of every
|
|
directory entry is a multiple of 4 (since the kernel complains if it
|
|
isn't).
|
|
|
|
Added a check to e2fsck to make sure that a directory entry isn't a
|
|
link to the root directory, since that isn't allowed.
|
|
|
|
Added a check to e2fsk to now make sure the '.' and '..' directory
|
|
entries are null terminated, since the 2.0 kernel requires it.
|
|
|
|
Added check to write_bitmaps() to make sure the superblock doesn't get
|
|
trashed if the inode or block bitmap is marked as being block zero.
|
|
|
|
Added checking of the new feature set fields in the superblock, to
|
|
avoid dealing with new filesystem features that this package wasn't
|
|
set up to handle.
|
|
|
|
Fixed a fencepost error in ext2fs_new_block() which would occasionally
|
|
try to allocate a block beyond the end of a filesystem.
|
|
|
|
When the UUID library picks a random IEEE 802 address (because it
|
|
can't find one from a network card), it sets the multicast bit, to
|
|
avoid conflicting with a legitimate IEEE 802 address.
|
|
|
|
Mke2fs now sets the root directory's owner to be the real uid of the
|
|
user running mke2fs. If the real uid is non-zero, it also sets
|
|
the group ownership of the root directory to be the real group-id of
|
|
the user running mke2fs.
|
|
|
|
Mke2fs now has more intelligent error checking when it is given a
|
|
non-existent device.
|
|
|
|
When badblocks is given the -vv option, it now updates the block that
|
|
it is currently testing on every block.
|
|
|
|
Fixed a bug in fsck where it wouldn't modify the PATH envirnoment
|
|
currently correctly if PATH wasn't already set.
|
|
|
|
Shared libraries now built with dependencies. This allows the shared
|
|
library files to be used with dlopen(); it also makes the transition
|
|
to libc 6 easier, since ld.so can tell which libc a particular shared
|
|
library expects to use.
|
|
|
|
Programmer's notes:
|
|
-------------------
|
|
|
|
Added new abstraction (defined in dblist.c) for maintaining a list of
|
|
blocks which belongs to directories. This is used in e2fsck and other
|
|
programs which need to iterate over all directories.
|
|
|
|
Added new functions which test to see if a contiguous range of blocks
|
|
(or inodes) are available. (ext2fs_*_bitmap_range).
|
|
|
|
Added new function (ext2_inode_has_valid_blocks) which returns true if
|
|
an inode has valid blocks. (moved from e2fsck code).
|
|
|
|
Added new function (ext2fs_allocate_tables) which allocates the
|
|
meta-data blocks as part of initializing a filesystem. (moved from
|
|
mke2fs code).
|
|
|
|
Added a new I/O manager for testing purposes. It will either allow a
|
|
program to intercept I/O requests, or print debugging messages to
|
|
trace the activity of a program using the I/O manager.
|
|
|
|
The badblocks_list functions now store the bad blocks in a sorted
|
|
order, and use a binary search to speed up badblocks_list_test.
|
|
|
|
The inode scan function ext2fs_get_next_inode() may now return a soft
|
|
error returns: MISSING_INODE_TABLE and BAD_BLOCK_IN_INODE_TABLE in
|
|
those cases where part of an inode table is missing or there is a bad
|
|
block in the inode table.
|
|
|
|
Added a new function (ext2fs_block_iterate2) which adds new arguments to
|
|
the callback function to return a pointer (block and offset) to the
|
|
reference of the block.
|
|
|
|
Added new function (ext2fs_inode_scan_goto_blockgroup) which allows an
|
|
application to jump to a particular block group while doing an inode
|
|
scan.
|
|
|
|
The badblocks list functions were renamed from badblocks_* to
|
|
ext2fs_badblocks_*. Backwards compatibility functions are available
|
|
for now, but programs should be modified to use the new interface.
|
|
|
|
Some of the library functions were reorganized into separate files to
|
|
reduce the size of some programs which statically link against the
|
|
ext2 library.
|
|
|
|
Put in some miscellaneous fixes for the Alpha platform.
|
|
|
|
|
|
E2fsprogs 1.06 (October 7, 1996)
|
|
================================
|
|
|
|
Fixed serious bug in e2fsck: if the block descriptors are bad, don't
|
|
smash the backup copies in ext2fs_close(). (The problem was that when
|
|
e2fsck -p discovered the problem, while it was closing the filesystem
|
|
and exiting, it was also blowing away the backup superblocks on the
|
|
disk, which was less than friendly.) We now make it the case that we
|
|
only write out the backup superblock and the back block descriptors if
|
|
the filesystem is completely free from problems.
|
|
|
|
Fixed a bug in block_interate in the lib/ext2fs library which caused
|
|
e2fsck to fail on GNU Hurd-created filesystems.
|
|
|
|
Add support for Linux/FT's bootloader, which actually uses
|
|
EXT2_BOOT_LOADER, and sets its mode bits which caused e2fsck to want
|
|
to clear the inode.
|
|
|
|
Add support for the "A" (no atime update) attribute. (Note: this
|
|
attribute is not yet in production kernels.)
|
|
|
|
The test suite is not automatically run when doing a "make all" from
|
|
the top level directory. Users should manually run "make check" if
|
|
they wish to run the test suite.
|
|
|
|
Upon a preenhalt(), make the printed message more explicit that
|
|
running e2fsck "MANAULLY" means without the -p or -a options.
|
|
|
|
In e2fsck, if a disconnected inode is zero-length, offer to clear it
|
|
instead of offering to connect it to lost+found.
|
|
|
|
In e2fsck, if a filesystem was just unmounted uncleanly, and needs
|
|
e2fsck to be run over it, change e2fsck to explicitly display this
|
|
fact.
|
|
|
|
For dumpe2fs and e2fsck, cause the -V option to print out which
|
|
version of the ext2fs library is actually getting used. (This will
|
|
help detect mismatches of using a 1.06 utility with a 1.05 library,
|
|
etc.)
|
|
|
|
Programmers' notes:
|
|
-------------------
|
|
|
|
EXT2_SWAP_BYTES was changed to EXT2_FLAG_SWAP_BYTES, which better fits
|
|
the naming convention.
|
|
|
|
In ext2fs_initialize(), make sure the description for the inode bitmap
|
|
is correctly initialize.
|
|
|
|
Fixed minor type typo in ext2fs_allocate_generic_bitmap();
|
|
|
|
E2fsprogs 1.05 (September 7, 1996)
|
|
==================================
|
|
|
|
Add support for new fields in the ext2 superblock --- volume name,
|
|
volume UUID, and last mounted field. Dumpe2fs displays these fields,
|
|
tune2fs and mke2fs allows you to set them. E2fsck will automatically
|
|
generate a UUID for those volumes that don't have them.
|
|
|
|
Put in support for e2fsck to recognize HURD specific ext2 features ---
|
|
most notably, the translator block. The e2fsprogs tools will now use
|
|
the creator_os field in the superblock to correctly handle different
|
|
OS-specific variants of the ext2 filesystem.
|
|
|
|
E2fsck now fixes inodes which have a the deletion time set, but which
|
|
have a non-zero i_link_count field by offering to clear the deletion
|
|
time. Previously e2fsck assumed that the inode was deleted (per 0.3c
|
|
ext2 kernel behavior) and offered to unlink the file.
|
|
|
|
If e2fsck sets the clean bit, but nothing else, set the exit code
|
|
FSCK_NONDESTRUCT. After all, e2fsck did fix a filesystem error --- it
|
|
set the filesystem valid bit when it was previously cleared. :-) This
|
|
was needed to make the HURD fsck driver happy.
|
|
|
|
If the user refuses to attach an unattached inode, e2fsck will no
|
|
longer set the inode's link count. Otherwise, the inode would end up
|
|
getting marked as unused, which might cause loss of data later.
|
|
|
|
Make the message issued by e2fsck when the superblock is corrupt less
|
|
confusing for users. It now mentions that another reason for the
|
|
"corrupt superblock" message might be that the partition might not be
|
|
an ext2 filesystem at all (it might swap, msdos filesystem, ufs, etc.)
|
|
|
|
Make the libext2 library more robuest so that e2fsck won't coredump on
|
|
an illegal superblock where the blocksize is zero. (f_crashdisk is
|
|
the test case).
|
|
|
|
By default, create filesystems where the default checkinterval is 6
|
|
months (180 days). Linux servers can be robust enough that 20 reboots
|
|
can be a long, long time.
|
|
|
|
Added configure flag --enable-old-bitops, which forces the bitops to
|
|
use the old (native) bitmask operations. By default on the sparc
|
|
platform, the standard ext2 bit ordering is now used.
|
|
|
|
Added a new feature to e2fsck to byte-swap filesystems; this can be
|
|
used to convert old m68k filesystems to use the standard byte-order
|
|
storage for the superblock, inodes, and directory blocks. This
|
|
function is invoked by using the '-s' option to e2fsck.
|
|
|
|
Debugfs's "dump" command has been enhanced so that it writes out the
|
|
exact size of the file so that the nulls at the end of the file are
|
|
eliminated. The command also accept a new "-p" option which will
|
|
attempt preserve to preserve the ownernship, permissions, and
|
|
file modification/access times.
|
|
|
|
Debugfs has two new options, -f and -R. The -R option allows the user
|
|
to execute a single debugfs command from the command line. The -f
|
|
option allows the user to specify a "command file" containing debugfs
|
|
commands which will get executed.
|
|
|
|
Dumpe2fs now pretty prints the check interval, instead of just
|
|
printing the check interval as a number of seconds.
|
|
|
|
Fix bugs in debugfs: the params command when no filesystem is opened
|
|
no longer causes a core dump. It is now possible to unlink a file
|
|
when a pathame containing a '/' is specified.
|
|
|
|
Tune2fs has a new -C option which sets the number of times the
|
|
filesystem has been mounted.
|
|
|
|
Fix the chattr '-v' option so that it actually works. Chattr was
|
|
being buggy about the -v option parsing.
|
|
|
|
Programmers' notes:
|
|
-------------------
|
|
|
|
The directory lib/uuid contains a set of library routines to generate
|
|
DCE compatible UUIDs.
|
|
|
|
Extended ext2fs_namei() to handle symbolic links. Added new function
|
|
ext2fs_nami_follow() which will follow last symbolic link in the case
|
|
where the pathname points to a sym link.
|
|
|
|
The ext2fs_block_iterate function will now return the HURD translator
|
|
block, if present. The new flag BLOCK_FLAG_DATA_ONLY will cause the
|
|
iterator to return data blocks only. The ext2fs.h file now defines
|
|
constants BLOCK_COUNT_IND, BLOCK_COUNT_DIND, BLOCK_COUNT_TIND, and
|
|
BLOCK_COUNT_TRANSLATOR, which are the magic values passed in the block
|
|
count field of the iterator callback function.
|
|
|
|
The test script driver now takes an optional second argument, which is
|
|
the test case to be run. This allows you to run a test case without
|
|
needing to run the entire test suite.
|
|
|
|
On Linux ELF systems, install the .so files in the correct places
|
|
(/usr/lib). The .so files must be stored in the same directory as the
|
|
.a files.
|
|
|
|
Fixed miscellaneous HURD compilation issues with header file being
|
|
included in the right order.
|
|
|
|
Fixed debugfs so that it resets optind to zero, not one, since setting
|
|
optind to zero is more correct.
|
|
|
|
|
|
E2fsprogs 1.04 (May 16, 1996)
|
|
=============================
|
|
|
|
First "official" (1.03 was a limited release only) to support building
|
|
e2fsprogs under Linux 2.0 kernels (as well as late model 1.3 and 1.99
|
|
kernels).
|
|
|
|
This package includes a RPM specs file, that it can be built using the
|
|
RedHat Package Manager.
|
|
|
|
E2fsck now prints a hint that if there are lots of incorrectly located
|
|
inode bitmaps, block bitmaps, and inode table blocks, the user might
|
|
want to try using e2fsck -b 8193 first, to see if that fares any
|
|
better.
|
|
|
|
For ext2 filesystem written with the hurd, debugfs will now print out
|
|
the translator field when printing an inode structure.
|
|
|
|
Lots of miscellaneous linking/installation cleanups:
|
|
|
|
Libraries are now linked using a relative pathname, instead of
|
|
relying on -L working correct. It doesn't, in many cases, including
|
|
current versions of GNU ld. This guarantees that the build tree is
|
|
linking with the right libraries, instead of the ones installed in
|
|
/usr/lib.
|
|
|
|
Header files, man pages, and the et/ss shell scripts are now
|
|
generated using a custom substitution script, instead of relying on
|
|
the configure script. This prevents needless recompilation of
|
|
files; in addition, the custom substitution script is much faster.
|
|
|
|
e2fsck may now be linked dynamically, by using the
|
|
--enable-dynamic-e2fsck flag to configure. This is not recommended,
|
|
since it increases e2fsck's dependence on other files, but some
|
|
people need to save disk space, and other critical programs on their
|
|
systems were being linked dynamically anyway.
|
|
|
|
Programs such as fsck which didn't need to be linked against
|
|
libext2fs (or mke2fs which didn't need to be linked against libe2p)
|
|
only link against libraries they actually need. Otherwise, those
|
|
programs would require the presense of libraries that otherwise
|
|
could be removed from a rescuse diskette.
|
|
|
|
The ss include files are now installed correctly so they can
|
|
actually be used by another package.
|
|
|
|
If the profiling libraries are built, they are now installed on a
|
|
"make install-libs".
|
|
|
|
|
|
E2fsprogs 1.03 (March 27, 1996)
|
|
===============================
|
|
|
|
Change the m68k bit numbering for bitmasks to match the bit numbering
|
|
used by all other ext2 implementations. (This change was requested by
|
|
the m68k kernel development team.)
|
|
|
|
Support (in-development) filesystem format revision which supports
|
|
(among other things) dynamically sized inodes.
|
|
|
|
Fixed a bug in the ext2 library so that an intelligent error is
|
|
returned if mke2fs is run with a ridiculously small number of blocks
|
|
for a partition.
|
|
|
|
Fixed a bug in the ext2 library which required that the device be
|
|
openable in read/write mode in order to determine its size. This
|
|
caused e2fsck -n to require read/write access when it was not
|
|
previously necessary.
|
|
|
|
Fixed a bug in e2fsck which casued it to occasionally fail the test
|
|
suite depending on which version of the floating point library it was
|
|
using.
|
|
|
|
Fixed a bug in e2fsck so that it now halts with a fatal error when
|
|
certain superblock consistency checks fail. Previously it continued
|
|
running e2fsck, with some potential confusing/damaging consequences.
|
|
|
|
Added new flag to fsck which allows the root to be checked in parallel
|
|
with other filesytems. This is not the safest thing in the world to
|
|
do, but some system administrators really wanted it.
|
|
|
|
Fixed -Wall flames in lib/ss.
|
|
|
|
|
|
E2fsprogs 1.02 (January 16, 1996)
|
|
=================================
|
|
|
|
Fix to allow e2fsprogs to be compiled on recent 1.3 (pl45+) kernels.
|
|
|
|
Change e2fsck to print statistics of how many non-contiguous files are
|
|
on the system. Note that a file which is larger than 8k blocks, it is
|
|
guaranteed to be non-contiguous.
|
|
|
|
In mke2fs, print a warning message if a user tries to format a whole
|
|
disk (/dev/hda versus /dev/hda1). If a user really wants to format a
|
|
whole disk, the -F (force) option forces mke2fs to format a whole disk
|
|
as a filesytem.
|
|
|
|
Fix a bug in fsck where in some cases it might start checking
|
|
partitions in the next pass before it finishes checking partitions in
|
|
the current pass. This still won't cause two partitions on the same
|
|
disk will be checked, so it's rarely a problem in real life.
|
|
