ext2_fs.h: New feature assignments for
EXT2_FEATURE_COMPAT_RESIZE_INODE for Andreas Dilger and
EXT3_FEATURE_COMPAT_DIR_INDEX for Daniel Phillips. Synchronize kernel
function prototypes (which don't matter for e2fsprogs) with Linux
2.4.4.
fsck.c (device_already_active): If we're not able to determine the
base device, we should assume that the device is already active in
order to force serialization.
parse.c, compare.c: Include string.h to fix gcc -Wall complaints.
gen_uuid.c: Define _SVID_SOURCE to avoid gcc -Wall errors because some
required structures wouldn't be otherwise defined. Fix a minor gcc
-Wall nit in the declaration of get_random_fd().
tune2fs.c (parse_tune2fs_options): Interpret -c 0 as -c -1 (for
backwards compatibility with older kernels). -c 0 makes more sense to
users.
tune2fs.8.in:
Update tune2fs manual papge so that it is up to date.
tune2fs.c (remove_journal_device): If the force flag is given, tune2fs
will remove the journal device information from the superblock even if
tune2fs failed to open the journal device or otherwise other failed to
remove the filesystem from journal device.
(parse_tune2fs_options): Fix -j option so that it works (it was
missing the open_flag being set to EXT2_FLAG_RW).
(main): Accept "-U clear" to set a null UID.
mke2fs.c (create_journal_dev): Call ext2fs_create_journal_superblock()
first, so if it's going to error out, the user finds out before
waiting for the entire device to get zero'ed.
ChangeLog, util.c:
util.c (parse_journal_opts): Remove code which allowed a bare number
to be treated as a journal size.
ismounted.c (check_mntent): Check /proc/mounts on Linux systems before
checking /etc/mtab. The EXT2_MF_READONLY flag is now set from the
/etc/mtab options field for all filesystems, not just the root
filesystem. Add debugging code to make it easier to test
ext2fs_check_if_mounted().
mkjournal.c (ext2fs_create_journal_superblock): Add safety check;
return an error if there's an attempt to create a journal less than
1024 filesystem blocks.
ext2_err.et.in, mkjournal.c: Change EXT2_JOURNAL_NOT_BLOCK and
EXT2_NO_JOURNAL_SB to be EXT2_ET_*.
super.c (check_super_block): Fix bad calculation of inodes_per_block,
and tighten min/max checks to be a bit more paranoid. Thanks to
Andreas Dilger for pointing out this bug.
debugfs.c (dump_blocks, dump_inode, internal_dump_inode): Add
internal_dump_inode() interface for the logdump command.
logdump.c: Imported code from Stephen Tweedie to dump the ext3 journal.
ke2fs.8.in, tune2fs.8.in: Change man paegs to document that the
journal must be bewteen 1024 and 10,240 file system blocks.
mke2fs.c, tune2fs.c: Change to use figure_journal_size()
util.c, util.h (figure_journal_size): Change journal_default_size into
routine which also converts the requested journal size into filesystem
blocks and does bounds checking to make sure the journal is sized
reasonably. Renamed function to journal_default_size.
parse_journal_opts): Remove bounds check for the journal size, since
this is now done in figure_journal_size, and based on the number of
filesystem blocks, as opposed to using the absolute size of the
journal.
bitops.h (ext2fs_swab16, ext2fs_swab32): Add i386 assembly inline
functions.
tst_byteswap.c: New function to test the byteswap functions. Add to
regression test suite.
mke2fs.c (main): Flush out the "creating journal" message. Also
handle the case where the default journal size returns zero blocks ==
no journal. Print out how often the filesystem will be checked.
mkjournal.c (ext2fs_create_journal_superblock): Fix the setting of
s_first for external devices to always be 1, since jsb->s_first is
always relative to the start of the journal superblock. Use htonl(1)
when setting s_nr_users.
pass1.c (check_blocks): Fix large file checking code so that files >
2GB are considered large files, and restrict directories from being >
2GB.
version.h:
Update for WIP release.
tune2fs.c, mke2fs.c, tune2fs.8.in, mke2fs.8.in: Change user interface
so that -J is used to specify journal options, and -j is used to
request creation of a journal using default values. (This is a UI
change, but we haven't done a formal release, and it makes things much
more consistent with the rest of the options out there.)
tune2fs.c: Add support for removing a filesystem from an external
journal; we correctly remove the filesystem UUID from the external
journal's filesystem list.
util.h, util.c (journal_default_size): New function from Andreas
Dilger to calculate an appropriate default journal size given a
filesystem size.
util.c (parse_journal_opts): Allow the creation of a journal as small
as 1MB.
mkjournal.c (ext2fs_add_journal_device): Fix bug where the device
number of the filesystem (instead of the journal) was being dropped
into s_journal_dev.
ChangeLog, dumpe2fs.c:
dumpe2fs.c (print_journal_information): Use s_first_data_block to find
the correct block to read the journal superblock.
tune2fs.c: Changed the external journal code so that it simply adds a
filesystem to a journal; the journal must have bene created via
"mke2fs -O journal_dev /dev/XXX".
mke2fs.c: Add support for creating an external journal device by using
the command "mke2fs -O journal_dev /dev/XXX". Also changed the
external journal code so -j device=/dev/XXX it simply adds a
filesystem to that journal; the journal must have been created via
separate step.
dumpe2fs.c (print_journal_information): Add support for dumping
information about an external journal device.
initialize.c (ext2fs_initialize): Add support for initializing the
ext2 superblock for external journal devices. This basically means we
don't bother to allocate any block group descriptors.
openfs.c (ext2fs_open): Only open external journal devices if the new
flag EXT2_FLAG_JOURNAL_DEV_OK is passed to ext2fs_open. When opening
such devices, don't try to read the block group descriptors, since
they're not there.
ext2_err.et.in (EXT2_NO_JOURNAL_SB): Add new error code
mkjournal.c: Export a new function,
ext2fs_create_journal_superblock(), which allocates and returns a
buffer containing a journal superblock. This is needed by mke2fs to
create an external journal. Rewrote ext2fs_add_journal_device() so
that it no longer creates the external journal, but rather adds a
filesystem to an existing external journal. It handles all of the
UUID manipulation.
ext2fs.h: List the EXT3_FEATURE_JOURNAL_DEV as a flag supported by the
library. Define the EXT2_FLAG_JOURNAL_DEV_OK. Changed function
prototype for ext2fs_add_journal_device().
