Add support for OV-style continuation (closes Debian bug #191900).
Move /usr/include/com_err.h from the e2fslibs-dev package to the
comerr-dev package. (closes Debian bug #191899)
tune2fs to use the test I/O manager.
The test I/O manager has been changed to not do anything extra by
default, unless the TEST_IO_FLAGS and/or TEST_IO_BLOCK environment
variables are set, which controls what I/O operations are logged and
a block number to watch, respectively. The log messages are sent to
stderr by default, unless a filename is specified via the
TEST_IO_LOGFILE environment variable.
Fix typo's in README.subset
Change debian control file so it doesn't bomb out if the EVMS FSIM
is not there, since it is not built on the Hurd. Resolves Debian
bug #189687.
Fixed possible hangs caused by bugs in calling waitpid, and not
setting the pipe to non-blocking mode. Also fixed a file descriptor
leak. Made sure all functions call log entry/exit functions.
from the system PRNG (i.e., random/srandom, seeded from
the time, pid, and uid) in case /dev/random isn't doing
the right thing on a particular system. It doesn't hurt,
and it can help, in the case of a buggy /dev/random.
instead of <com_err.h>, so the current version of the header file
is used.
Add a --build-tree option to compile_et to make sure that it uses
the et_?.awk files from the build tree.
Remove legacy support for varargs.h, K&R C, and pre-POSIX signal
support. Also fixed gcc -Wall nits.
structure from the internal error_table.h to com_err.h,
since it now needs to be public.
et_c.awk, et_h.awk: Import changes from krb5's et library so
that the error_table structure is defined and available
publically.
error_message.c: Import krb5 and heimdall com_err extensions to
the et library.
1) Only one tag with a particular name can be attached to a device
at a time. This significantly simplifies the library, and was needed
to allow the cache file to be re-read and changes integrated into the
in-core version of the data structure in a simpler fashion than earlier
versions of the library.
2) To accomodate this, the ext2/ext3 filesystems are now always tagged
as "ext2" type filesystems. Ext3 filesystems are tagged with a
SEC_TYPE tag with the value ext3.
3) The new blkid_read_cache() function checks the mod time of the
cache file, and if the file has been changed since the last time the
cache file was read into memory, it is re-read. This function is now
called before probing all of the devices in the system or searching
all devices in the cache for a specific tag value.
4) After probing all devices, blkid_flush_cache() is called to write
out the cache file. This assures that all of the hard work involved
in doing a blkid_probe_all() is saved to disk.
read.c (parse_tag): Do not return that blkid_tag when parsing
the blkid.tag file.
resolve.c (blkid_get_token, blkid_get_tagname_devname): Fold in
code from removed functions
tag.c (blkid_create_tag): Don't return the newly tag strcture
any more, as it's not needed.
(blkid_find_tag_cache, blkid_get_tag_cache,
blkid_token_to_tag, blkid_find_tv_tags): Remove these
functions, as they are either only used once or have
interfaces that should be deprecated.
(blkid_find_tag_dev, blkid_find_head_cache): Replace use
of blkid_tag with one or two const char * type/value
arguments.
(blkid_find_dev_with_tag): Fold in code from removed functions
probe.h, probe.c: Use a more sophisticated set of byte-swapping
routines which are more compact and efficient. Drop
calculation of bid_free, since it's unnecessary. Avoid
save.c (blkid_save_cache): Set the permissions on the blkid
cache file to 644.
large number of inodes, then reduce the number of blocks
per group until we find a workable set of filesystem
parameters.
ext2_err.et.in (EXT2_ET_TOO_MANY_INODES): Add new error code.
unix_write_blk): Optimize routines so that we don't end up
searching the cache twice when a block isn't in the
cache. If reads are larger than READ_DIRECT_SIZE, don't
let them go through the cache.
blocks to be erroneously marked as dirty, so they would
get written back to the disk before they are evicted from
the cache. Harmless, but it slows down e2fsck
significantly.
Disable certain tests that depend on the byteswapping functions
being present so that "make check" succeeds even if --disable-swapfs
is passed to the configure script.
support for loopback-mounted filesystems. Check /etc/mtab
if /proc/mounts doesn't turn up any mount flags, since
/etc/mtab has the loopback image filename, instead of
/dev/loop0. Also, check based on st_dev and st_ino, so
that if a relative pathname or a pathnames using symbolic
links are used, we can detect the the filesystem correctly
in those cases. (Addresses Sourceforge bug #619119)
don't try the FDFLUSH ioctl that was required for floppies
with older kernels. This avoids needless whining from the
MD device driver. (Addresses Sourceforge bug #545832).
wrong group_block to ext2fs_descriptor_block_loc if we're
using the backup superblock/block group descriptors.
(ext2fs_descriptor_block_loc): If we're using the backup
superblock descriptors, use the backup descriptor block in
the next block group.
the filesystem was created. It is set via mke2fs, and printed
via list_super2() (which is called by dumpe2fs).
Also, list_super2() will now print "n/a" if the last mount time
(s_mtime) is zero.
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. Otherwise
the regression test suite will fail...
using a non-zero hash version (i.e., half MD4 or TEA hash).
The hash version wasn't getting copied into dx_dir->hashversion and
this caused the kernel to treat all directories if they were using the
legacy hash, which was Bad.
superblock. Dumpe2fs can now print out these fields, and they
can be modified using debugfs's set_super_value command. Also added
to debugfs was the ability to set s_uuid and s_journal_uuid features
as well.
Fixed up confusion caused by bad parameter names for
get_fs_limits(). Added missing conversion of
volume->vol_size from sectors to bytes. Fix up error
returns for unsupported tasks as EINVAL, not ENOSYS.
Use logical names for the API version numbers, since
the ABI is much more dependent on the headers. Add
code to byte-swap the superblock if necessary.
Revert the shlibs hack.
Makefile.in: Remove inode_io.o from the standard object files
in libext2fs, and only build it if debugfs is enabled
(it requires fileio.o, which is only built if
--disable-debugfs isn't specified to configure).
Z, and explain that chattr can't set or set these flags.
(Addresses Debian Bug #151990)
fsetflags.c (fsetflags), fgetflags.c (fgetflags.c), setflags.c
(setflags), getflags.c (getflags): Check to make sure the
file is a regular file or a directory before attempting to
use the ext2 ioctls. Otherwise, return EOPNOTSUPP.
(Addresses Debian Bug #152029).
a backwards incompatible change, but this should be OK since the kernel
MD4 ext3 code was only in the CVS tree, and hasn't generally escaped.
Add support for the TEA hash.
The iterate_on_dir function in libe2p has been changed to be more
general, so it relies less on the layout of struct dirent. We also
make sure the errno returned by the ioctl is returned by
fgetversion() and fsetversion().
the kernel version is 2.4.10 -- 2.4.17, since otherwise an
old version of glibc (built against 2.2 headers) will
interact badly with the workaround to actually cause more
problems. I hate it when the glibc folks think they're
being smarter than the kernel....
8192-byte and 16384-byte blocksize filesystems.
Change the default bytes-per-inode ratio of a new filesystem to be at most
one inode per block for large blocksizes.
Pratt. Fixed a selection bug and added checks to make
sure volumes are not mounted when creating the list of
volumes which can be mkfs'ed by the ext2/3 plugin.
the EXT2_SB() macro instead. Remove kernel function
prototypes also. This matches the 2.5 kernel, and
is also cleaner for other reasons. Whitespace cleanup.
mapping for a particular inode.
Fixed a bug in the libext2 library which broke ext2fs_bmap if no inode structre
was passed inside for here.
Fixed bad calling parameters to parse_ulong which broken the -b and -s
options to debugfs, as well as do_init, and the testb, setb, clearb functions.
file we are checking is a block device file before looking
at st_rdev, since it's not valid for normal files.
(is_swap_device): Move so that it is outside the
HAVE_MNTENT_H, so that it is always built.
functions which take an extra flags argument. The flag
EXT2_DIRBLOCK_V2_STRUCT 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.
Also fixed a bug in debugfs which used ext2_dir_entry_2 without
worrying about the above issue, with the net result that "ls -l"
would print an incorrect file type on big-endian systems.
an I/O object.
Export ext2_file_flush as a public interface.
Also minor cleanups to tighten code in other I/O abstractions, and to
mark a void * pointer as const in the ext2_file_write interface.
Add support for a new flag, DIRENT_FLAG_INCLUDE_REMOVED,
which will return deleted directory entries.
ext2fs_dir_iterate2 takes a new callback function which
is identical with the one used by
ext2fs_dblist_dir_iterate(). If the directory entry is
deleted, the callback function will be called with the
entry paraemter set to DIRENT_DELETED_FILE.
Makefile.in, alloc_stats.c (ext2fs_inode_alloc_stats,
ext2fs_block_alloc_stats): New functions which update
block/inode allocation statistics in the bitmaps, block
group descriptors, and superblock.
mkjournal.c (mkjournal_proc), mkdir.c (ext2fs_mkdir),
expanddir.c (expand_dir_proc), bb_inode.c
(clear_bad_block_proc, set_bad_block_proc,
ext2fs_update_bb_inode), alloc.c (ext2fs_alloc_block):
Update to use new block/inode allocation statistics.
ext2fs_check_if_mounted and ext2fs_check_mount_point which
determines whether or not the specified device is a swap
device by using /proc/swaps. More bulletproofing for
idiotic/careless system administrators!
since files which get dropped into that directory may have come
from a protected directory, and the system administrator may not
deal with immediately. (Addresses Debian bug #118443)
- Renamed linux/list.h to be linux/linked_list.h to work around a
problem caused by diet libc insistence to search the kernel
header files ahead of all other files in the include path,
including the user specified include files.
- Worked around a bug in diet libc which core dumps when using
putc with stderr by using fputs instead. As a bonus, this
also shaved a few bytes off of com_err.o.
- Fixed a real bug in debugfs which was detected because diet libc
was more sensitive than glibc when incorrectly using fclose()
where pclose() is required.
trying to unset the filesize limit if at all possible,
if a block device is getting opened. (The filesize limit
shouldn't be applied against writes to a block device, but
starting in 2.4.10, the kernel is doing this.)
file on adding a journal to an already-mounted filesystem,
try to clear the ext2 file attributes on an already
existing .journal file so that we don't fail if on a
partially added journal to the filesystem.
which signals that a particular inode should not have the
last bits of data (the "tail") be merged with another
file. This is necessary to keep programs like LILO happy.
Add a copyright statement to the libuuid man page which identifies it
as being under LGPL. While this is conveyed in the source code, it is
not mentioned anywhere in the man pages or other documentation.
/etc/mtab to make sure the filesystem is really mounted,
since some broken distributions (read: Slackware) have
buggy boot scripts that 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.)
the a valid .info file can be made. Use @deftypefun to
define functions. Change the e-mail address where bug

isnull.c (uuid_is_null), pack.c (uuid_pack),
parse.c (uuid_parse), unpack.c (uuid_unpack),
unparse.c (uuid_unparse), uuid.h, uuidP.h,
uuid_time.c (uuid_time, uuid_type, uuid_variant):
Use const for pointer variables that we don't modify. Add
the appropriate ifdef's in uuid.h to make it be C++ friendly.
unconditional ext2_flush() call. Also made ext2_flush() more
efficient when the superblock is modified after the filesystem has
been flushed, and make it clear the superblock dirty flag
after doing the superblock/block group descriptor flush.
included if EXT2FS_ENABLE_SWAPFS is defined, since we need to support
byte swapping even if we don't support the conversion functions.
(Fixes Debian bug #101686).
the byte-swapping code all assumes the ext2_dir_entry structure.
(It's a question of whether or not name_len should be byte-swapped or
not, and whether it's a 16 bit or 8 bit field.)
Makefile.in: Fix bug in installation of ext2_types.h. It is a file
which is generated and is therefore found in the build directory, not
source directory.
ismounted.c (check_mntent_file): Use a test file in / to check to see
if the root filesystem is mounted read-only. This protects against
the case where /etc might not be on /, as well as the case where
/etc/mtab doesn't exist. (Both are should-never happen scenarios, but
you never know...)
ext2_types.h.in: If linux/types.h has been defined, then don't try to
redefine the typedefs.
ChangeLog, Makefile.in:
Makefile.in: Make the install target depend on $(SUBS) to accomodate
the fools who want to compile and install e2fsprogs as root using just
one command.
setsuper.c: Add s_lastcheck field to the fields which can be modified
using set_super_value. (Suggested by Andreas Dilger)
ChangeLog, Makefile.in:
Makefile.in (HFILES): Add ext2_types.h to the list of files which
should be installed.
Makefile.in: Limit some .o files from being included into the library
if --disable-debugfs, --disable-swapfs, --disable-imager, or
--disable-resizer are used.
dumpe2fs.c: Use WORDS_BIGENDIAN to determine whether or not we're
(not) using i386 byte order.
dumpe2fs.c, mke2fs.c: Stop using the compatibility badblocks function,
and use the ext2fs_badblocks_* functions instead.
ChangeLog, inode.c, tst_iscan.c:
inode.c, tst_iscan.c: Stop using the compatibility badblocks function,
and use the ext2fs_badblocks_* functions instead.
ChangeLog, badblocks.c:
badblocks.c: Stop using the compatibility badblocks function, and use
the ext2fs_badblocks_* functions instead.
Makefile.in, gen_bitmap.c, bitops.h: Move inline functions
ext2fs_mark_generic_bitmap and ext2fs_unmark_generic_bitmap to
gen_bitmap.c as normal functions. (This saves space and doesn't
significantly change the speed of e2fsck on a P-III.)
ChangeLog:
Add missing log entry for unix.c.
