2007-06-18Don't write changes to the backup superblocks by defaultTheodore Ts'o2-0/+7
This patch changes ext2fs_open() to set EXT2_FLAG_MASTER_SB_ONLY by default. This avoids some problems in e2fsck (reported by Jim Garlick) where a corrupt journal can end up writing the bad superblock to the backups. In general, only e2fsck (after the filesystem is clean), tune2fs, and resize2fs should change the backup superblocks by default. Most callers of ext2fs_open() should not be touching anything where the backups should be touched. So let's change the defaults to avoid potential problems.

2007-05-18Store the RAID stride value in the superblock and take advantage of itTheodore Ts'o2-1/+13
Store the RAID stride value when a filesystem is created with a requested RAID stride, and then use it automatically in resize2fs. Signed-off-by: "Theodore Ts'o" <tytso@mit.edu>
2007-03-18[COVERITY] Fix missing return code check for ext2fs_write_inodeBrian Behlendorf2-1/+8
Found 2 of the three places where a return code for ext2fs_write_inode() was not being checked. The second fix in e2fsck/emptydir.c is basically just to shut coverity up even though it really is unnecessary. Coverity ID: 1: Checked Return Signed-off-by: Brian Behlendorf <behlendorf1@llnl.gov> Signed-off-by: "Theodore Ts'o" <tytso@mit.edu>
2006-12-26Use the newer add/remove_error_table com_err interfacesTheodore Ts'o2-1/+7
Change all of the e2fsprogs programs to use the newer add_error_table() and remove_error_table() interfaces instead of the much older initialize_*_error_table() function. Signed-off-by: "Theodore Ts'o" <tytso@mit.edu>
2006-10-02Fix resize2fs error msgs if the fs or kernel doesn't support on-line resizeTheodore Ts'o2-2/+29
Check to make sure the filesystem has a resize inode if it is needed to grow the filesystem. Print the correct error message if the kernel returns an ENOTTY error to the group extend ioctl Addresses Debian Bug: #380548 Signed-off-by: "Theodore Ts'o" <tytso@mit.edu>

2006-09-12Add checks to make sure inode counts don't overflow a 32-bit valueEric Sandeen2-0/+11
Signed-off-by: Eric Sandeen <esandeen@redhat.com>
2006-09-12Fix signed vs unsigned printf format strings for block and inode numbersEric Sandeen2-2/+6
There were still some %d's lurking when we print blocks & inodes; also many of the counters in the e2fsck_struct were signed, and probably need to be unsigned to avoid overflows. Signed-off-by: Eric Sandeen <esandeen@redhat.com>
2006-09-12Remove unused variablesEric Sandeen2-3/+5
Signed-off-by: Eric Sandeen <esandeen@redhat.com>
2006-08-30Fix potential 2**32-1 overflow by using e2p_percent()Theodore Ts'o3-3/+8
Add a new functiom, e2p_percent(), which correct calculates the percentage of a number based on a given percentage, without worrying about overflow issues. This is used where we calculate the number of reserved blocks using a percentage of the total number of blocks in a filesystem. Based on patches from Eric Sandeen, but generalized to use this new function. Signed-off-by: "Theodore Ts'o" <tytso@mit.edu> Signed-off-by: Eric Sandeen <esandeen@redhat.com>
2006-08-30Detect overflows in loop countersEric Sandeen2-1/+7
For loops such as: for (i=1; i <= fs->super->s_blocks_count; i++) { <do_stuff> } if i is an int and s_blocks_count is (2^32-1), the condition is never false. Change these loops to: for (i=1; i <= fs->super->s_blocks_count && i > 0; i++) { <do_stuff> } to stop the loop when we overflow i Signed-off-by: Eric Sandeen <esandeen@redhat.com> Signed-off-by: "Theodore Ts'o" <tytso@mit.edu>
2006-08-30Fix potential 2**32-1 overflow problems by ext2fs_div_ceil()Theodore Ts'o2-7/+11
Add a new function, ext2fs_div_ceil(), which correctly calculates a division of two unsigned integer where the result is always rounded up the next largest integer. This is used everywhere where we might have previously caused an overflow when the number of blocks or inodes is too close to 2**32-1. Based on patches from Eric Sandeen, but generalized to use this new function Signed-off-by: "Theodore Ts'o" <tytso@mit.edu> Signed-off-by: Eric Sandeen <esandeen@redhat.com>

2006-05-14Add RAID stride support to resize2fsTheodore Ts'o3-5/+83
Resize2fs will now automatically determine the RAID stride parameter that had been used to create the filesystem, and use that for newly created block groups. The RAID stride parameter may also be manually specified on the command line using the new -S option to resize2fs. Signed-off-by: "Theodore Ts'o" <tytso@mit.edu>
2006-03-18Fix format statements to make e2fsprogs programs 32-bit cleanTakashi Sato3-6/+9

2006-03-18Change resize2fs open modes for mounted and unmounted filesystemsTheodore Ts'o2-1/+13
If the filesystem is mounted, open it in read-only mode since the userspace program should not try to modify it directly. If the filesystem is not mounted, open it in exclusive mode to avoid potential problems (such as someone trying to mount the filesystem while it is being resized). Signed-off-by: "Theodore Ts'o" <tytso@mit.edu>
2006-03-17Add support for on-line resizing to resize2fsTheodore Ts'o7-96/+342

2005-08-08Fix fencepost error in resize2fs caught by valgrindTheodore Ts'o2-1/+15
There was a off-by-one fencepost error in the logic used to check if we avoid copying zero-filled blocks when moving an inode table down by a block or two. Thanks to valgrind for catching it. As far as I know this fencepost error wasn't causing any actual problems, but it was definitely a bug. Signed-off-by: "Theodore Ts'o" <tytso@mit.edu>

2005-01-05Add new function in e2p for parsing the number of blocks on the command lineTheodore Ts'o3-42/+25
for mke2fs and resize2fs, and use this function so that filesystem size inputs to e2fsprogs command line programs are parsed consistently.

correctly. Update Makefile dependencies. Update "make depend" production so that it filters out comments inserted by newer gcc compilers. Remove sync from e2fsck's "make all" target.
2004-11-30Add support for passing options to the io layer using the URL syntax. For Theodore Ts'o2-3/+11
example, /tmp/test.img?offset=1024. Multiple options can separated using the & character, although at the moment the only option implemented is the offset option in the unix_io layer.

2004-04-03Refine the build process to avoid re-running subst all the time on Theodore Ts'o2-4/+11
some generated files, by having subst update the modtime on these files even when the generated file hasn't changed. We do this with generated files that do not have any downstream dependencies.

2003-07-26Update for 1.34 release.Theodore Ts'o1-0/+4
2003-07-08In mke2fs and resize2fs, round the default size of the filesystem to Theodore Ts'o2-1/+25
be an even multiple of the pagesize to work around a potential Linux kernel bug. Use the testio manager in mke2fs if CONFIG_TESTIO_DEBUG is set.
2003-06-24Fix bug in resize2fs which caused it to fail on filesystems with aTheodore Ts'o2-0/+26
non-empty bad block list. Resize2fs now discards any blocks on the badblock list which are no longer part of the filesystem as the result of a filesystem shrink. (Note: this means that shrinking and then enlarging a filesystem is no longer a reversible operation; information about bad blocks in the part of the filesystem which is to be chopped off will be lost.)
2003-06-08resize2fs.8.in: Make explicit that you need to run resize2fsTheodore Ts'o2-2/+13
after using fdisk to adjust the partition size when expanding the filesystem. (Addresses Debian Bug #195616)
