E2fsprogs 1.36 (February 4, 2005)
|
|
=================================
|
|
|
|
All of the patches that were applied to Fedora Core 3's
|
|
e2fsprogs-1.35-11.2 have been integrated, although sometimes with a
|
|
lot of bug fixes first. Users of Fedora Core 3 are strongly
|
|
encouraged to upgrade to e2fsprogs 1.36 as soon as possible.
|
|
|
|
Add support for filesystem with the online resizing via resize inode
|
|
feature. Fixed numerous bugs from the Fedora patches. The Fedora
|
|
patches also didn't bother to do any consistency checking on the
|
|
resize inode, or add any tests to the regression test suite. The "-R
|
|
resize=4g" option to mke2fs was a no-op in the Fedora patches, despite
|
|
being listed in mke2fs's usage message. All of these shortcomings
|
|
have been corrected.
|
|
|
|
E2fsck can also also fix filesystems trashed by Fedora's resize2fs
|
|
program. In order to do this, the user must run the commands:
|
|
|
|
debugfs -w /dev/hdXXX -R "features ^resize_inode"
|
|
e2fsck -f /dev/hdXXX
|
|
|
|
Optionally, the ext2prepare command can be used to re-enable online
|
|
resizing after the filesystem has been fixed.
|
|
|
|
The fsck program will now accept an optional filedescriptor argument
|
|
to the -C option. (The Fedora version of this patch would sometimes
|
|
cause fsck to ignore a parameter on fsck's command line in some rare
|
|
cases, sigh.)
|
|
|
|
Make sure e2fsprogs doesn't write garbage into the reserved portion of
|
|
large inodes.
|
|
|
|
Make sure resize2fs releases the blocks belonging to the old inode
|
|
table blocks when moving the inode table. (Addresses Debian Bug:
|
|
#290894)
|
|
|
|
Skip the r_resize_inode test if resize2fs is not compiled (due to
|
|
configure --disable-resizer)
|
|
|
|
E2fsck now checks the summary filesystem accounting information, and
|
|
if any of the information is obviously wrong, it will force a full
|
|
filesystem check. (Addresses Debian Bug #291571)
|
|
|
|
Fix e2fsck to not complain when the resize_inode feature is enabled,
|
|
s_reserved_gdt_blocks is zero, and there is no DIND block allocated in
|
|
the resize inode.
|
|
|
|
Fix e2fsck to note delete symlinks that contain an extended attribute
|
|
after the ext_attr feature flag has been cleared. (Addresses Red Hat
|
|
Bugzilla #146284).
|
|
|
|
Add new utility program, copy_sparse.c, which is very useful
|
|
for dealing with large sparse files (such as e2image files).
|
|
|
|
Add support for jnl_blocks[] for debugfs's set_super_value.
|
|
|
|
Fix filefrag so that it works correctly with sparse files.
|
|
|
|
Filefrag -v will print first and last blocks.
|
|
|
|
Add interpretation of OS Creator values for FreeBSD and Lites in mke2fs
|
|
and dumpe2fs.
|
|
|
|
Add mke2fs support so that it can support filesystems larger than 4TB
|
|
automatically, by retrying with a 4k blocksize if the device size is
|
|
too big to be expressed using a 1k blocksize. (Addresses Sourceforge
|
|
bug #1106631)
|
|
|
|
Change blkid to test for NTFS first because Windows sometimes doesn't
|
|
clear enough of the partition to confuse the probing routines into
|
|
thinking the old filesystem type is still valid. (Addresses Debian
|
|
Bug #291990)
|
|
|
|
Add support for swap partition label and uuid's in the blkid library.
|
|
|
|
Add support to the blkid library to recognize Oracle ASM volumes.
|
|
|
|
Make blkid -t display all devices that match the specified criteria,
|
|
not just the first one, and work more consistently when the blkid
|
|
cache file is not available or set to /dev/null. (Addresses Debian
|
|
Bug #290530 and #292425)
|
|
|
|
Badblocks will now correctly display block numbers greater than
|
|
999,999,999 in its progress display.
|
|
|
|
The tune2fs program will not allow the user from setting a ridiculous
|
|
number of reserved blocks which would cause e2fsck to assume the
|
|
superblock was corrupt. E2fsck's standards for what is a ridiculous
|
|
number of reserved block has also been relaxed to 50% of the blocks in
|
|
the filesystem.
|
|
|
|
The blkid library will return vfat in preference to msdos, and ext3 in
|
|
preference to ext2 (if the journalling flag is set) so that mount will
|
|
do the right thing. (Addresses Debian bug #287455)
|
|
|
|
Mke2fs will now use the -E option for extended options; the old -R
|
|
(raid options) option is still accepted for backwards compatibility.
|
|
Fix a double-free problem in resize2fs. (Red Hat Bugzilla #132707)
|
|
|
|
Mke2fs will now accept a size in megabytes, gigabytes, and other units
|
|
(via "32m" or "4g" on the command line) if the user finds this more
|
|
convenient than specifying a block count.
|
|
|
|
Fix an obscure, hard-to find bug in "e2fsck -S" caused by an inode
|
|
cache coherency problem.
|
|
|
|
Debugfs now supports a new command, set_inode_field, which allows a
|
|
user to manually set a specific inode field more conveniently, as well
|
|
as set entries in the indirect block map.
|
|
|
|
Debugfs's set_super_value command has been enhanced so that the user
|
|
can set most superblock fields, including the date/time fields and
|
|
some of the more newly added superblock fields.
|
|
|
|
E2fsprogs programs now accept an offset to be passed to the file
|
|
specifiers, via the syntax: "/tmp/test.img?offset=1024".
|
|
|
|
E2fsprogs programs will now accept blocksizes up to 65536; kernel
|
|
support on the x86 doesn't exist for now, but it can be useful on
|
|
other architectures with page sizes greater than 4k. There are 2.6
|
|
kernel patches out there which enable this, but they are of this
|
|
writing still experimental.
|
|
|
|
The e2image command now takes the -s option which will scramble
|
|
directory entries for raw image files.
|
|
|
|
Fix a file descriptor leak in the filefrag program.
|
|
|
|
Make sure e2fsck doesn't crash when /proc/acpi/ac_adapter is not
|
|
present.
|
|
|
|
Fix bug in debugfs where kill_file would lead to errors when deleting
|
|
devices and symlinks. (Sourceforge Bugs #954741 and #957244)
|
|
|
|
Fix bug in the blkid library when detecting the ocfs1 filesystem
|
|
|
|
Remove obsolete EVMS 1.x and a.out DLL support.
|
|
|
|
E2fsck will attempt to recover from a journal containing illegal blocks.
|
|
|
|
Fixed two potential ordering constraint problems in e2fsck which might
|
|
cause the filesystem to be corrupted if e2fsck is interrupted during a
|
|
(extremely narrow) race window. Thanks to Junfeng Yang from the
|
|
Stanford Metacompilation group for pointing this out.
|
|
|
|
Fixed bug in e2fsck where it would not accurately detect whether or
|
|
not the system is running on adaptor if the ACPI device representing
|
|
the AC adapter didn't correspond to the what was used on IBM
|
|
Thinkpads.
|
|
|
|
Change e2fsck to accept directories greater than 32MB.
|
|
|
|
Fix e2fsck so that a checkinterval of zero disables a time-based check
|
|
of the filesystem.
|
|
|
|
Debugfs will check the DEBUGFS_PAGER environment variable in preference
|
|
to the PAGER environment variable. (Addresses Debian Bug #239547)
|
|
|
|
Tune2fs will not mark rewrite the superblock if the feature bitmasks
|
|
are not modified.
|
|
|
|
The debugfs program will set the filetype information when creating a
|
|
link.
|
|
|
|
Add debugfs -d option to use a separate source of data blocks when
|
|
reading from an e2image file.
|
|
|
|
Add e2image -I option which allows the e2image metadata to be
|
|
installed into a filesystem.
|
|
|
|
Fixed bug in the badblocks program which caused "done" to always
|
|
appear in English even when a translation was available. (Addresses
|
|
Debian Bug #252836)
|
|
|
|
The blkid program has a new option -o which controls the output format
|
|
of the blkid program; this is makes blkid more convenient to use in
|
|
shell scripts.
|
|
|
|
Fix a minor bug in uuid library, which was not using the full 14 bits
|
|
of clock sequence when generating UUID's.
|
|
|
|
Fix a Y8.8888K problem in the uuid library.
|
|
|
|
Logsave now creates a new session id for itself to avoid getting
|
|
killed by init when transitioning between init levels.
|
|
|
|
Change the licensing of the UUID library to be the 3-clause BSD-style
|
|
license; this allows Apple to use the uuid library in Darwin.
|
|
|
|
Add ocfs and ocfs2 probe support into the blkid library.
|
|
|
|
Fix a memory and file descriptor leak in the blkid library.
|
|
|
|
The blkid library will revalidate the device if the system time is
|
|
earlier than last verification time of the device, since that
|
|
indicates that the system time is probably not trustworthy.
|
|
|
|
The blkid library will override the default location of the blkid.tab
|
|
file by the BLKID_FILE environment variable, if it is available.
|
|
|
|
Change the getsize functions to use the BLKGETSIZE64 ioctl on Linux 2.6.
|
|
|
|
Add various portability fixes for lame new versions of glibc, Darwin
|
|
and GNU/KFreeBSD, as well as removing XSI:ism's. (Addresses Debian
|
|
Bugs #239934, #264630, #269044, #255589, #289133)
|
|
|
|
Add support for Windows 9x/NT under Cygwin.
|
|
|
|
Updated and clarified various man pages. (Addresses Debian Bugs #236383,
|
|
#241940, #238741, #242995, #256669, #268148, #256760, #273679)
|
|
|
|
Updated and fixed translations. (Addresses Debian bugs #244105, #262836)
|
|
|
|
Update the rpm spec files so that it works better with Fedora core 2
|
|
and RH9.
|
|
|
|
Fixed various Debian packaging issues (see debian/changelog). In
|
|
particular, fixed the Debian initrd scripts. (#241183, #248050,
|
|
#253595, #247775)
|
|
|
|
|
|
Programmer's notes:
|
|
-------------------
|
|
|
|
Fixed various gcc -Wall warnings.
|
|
|
|
The uuid library now has new functions uuid_unparse_upper() and
|
|
uuid_unparse_lower() which forces the case of the hex digits to be
|
|
upper case, or lower case.
|
|
|
|
The build process has been sped up by enhancing the subst program
|
|
to update the modtime on the generated files even when the generated
|
|
file hasn't changed.
|
|
|
|
The uuid library now uses C99 stdint.h types instead of custom types.
|
|
|
|
Updated config.guess and config.sub with newer versions from the FSF.
|
|
|
|
Removed out of date .cvsignore files from the source distribution.
|
|
|
|
The ext2fs_unlink() function will return an error if both the name and
|
|
inode number are unspecified, to avoid doing something surprising
|
|
(such as unconditionally deleting the first directory entry).
|
|
Directory entries are now deleted by coalescing them with the previous
|
|
directory entry if possible, to avoid directory fragmentation. This
|
|
is not an issue with the e2fsprogs suite, but may be a problem for
|
|
some of the users of libext2fs, such as e2tools.
|
|
|
|
Add support for version numbers of the form "1.36-rc1".
|
|
|
|
Fix build of mke2fs.static.
|
|
|
|
Add basic ext2fs library support for large (EA in inode) inodes.
|
|
|
|
The test_io mechanism can now abort after n reads or writes to a
|
|
particular block. The block is specified by TEST_IO_BLOCK environment
|
|
variable, and the read/write count by the TEST_IO_READ_ABORT and
|
|
TEST_IO_WRITE_ABORT environment variables. The block data is now only
|
|
dumped if the 0x10 bit is set in TEST_IO_FLAGS.
|
|
|
|
UUID_DEFINE() in the uuid library now creates a static variable, with
|
|
__attribute__ ((unused)) if we are using GCC, so that UUID_DEFINE can
|
|
be used in header files.
|
|
|
|
Add support for the install-strip and install-shlibs-strip targets, as
|
|
suggested by the GNU coding guidelines. "make install" no longer
|
|
strips the binaries which are installed.
|
|
|
|
Remove support for the --enable-old-bitops configure option which was
|
|
only for very old sparc systems.
|
|
|
|
Remove support for --enable-clear-htree; this was only needed during
|
|
the early development of the htree patch.
|
|
|
|
Use Linux-kernel-style makefile output so it is easier to see compiler
|
|
warnings.
|
|
|
|
Update gettext files to version 0.14.1.
|
|
|
|
Update to use autoconf 2.5x.
|
|
|
|
Improved support for compiling e2fsprogs under dietlibc.
|
|
|
|
Make e2fsprogs portable to Solaris and FreeBSD systems.
|
|
|
|
Add blkid_verify(), blkid_get_library_version(), and
|
|
blkid_parse_version_string() functions to the blkid library.
|
|
|
|
Add pkg-config files for e2fsprogs's libraries.
|
|
|
|
Fix "make uninstall" to so that it removes everything that is installed.
|
|
|
|
Add a configure --enable-maintainer-mode option which enables the
|
|
makefile rules to rebuild the configure script from configure.in, and
|
|
to rebuild the .gmo files in po directory.
|
|
|
|
Drop the sparc assembly bitwise operations; it's less efficient
|
|
than the GCC 3.4 compile code and triggers compiler warnings on
|
|
sparc64. Thanks to Matthias Andree for his analysis and suggestions.
|
