2008-07-13Define _XOPEN_SOURCE to 600 consistently for Solaris C99 supportTheodore Ts'o1-0/+2
Solaris's header files are very picky about which C compiler can be used for SUSv3 conformance. Use of C99 is not compatible with SUSv2 (_XOPEN_SOURCE=500), and C89 is not compatible with SUSv3 (_XOPEN_SOURCE=600). Since we need some SUSv3 functions, consistently use SUSv3 so that e2fsprogs will build on Solaris using c99. Signed-off-by: "Theodore Ts'o" <tytso@mit.edu>

2007-10-06e2fsck: backup superblocks if key constants have changedTheodore Ts'o1-0/+6
If the primary superblock differs from the backup superblock in certain key respects, force a full check (if e2fsck was invoked in preen mode). If the filesystem check passes cleanly, and the filesystem was opened in read/write mode, then write the primary superblock to all of the backups. Signed-off-by: "Theodore Ts'o" <tytso@mit.edu>

2007-09-07e2fsck: If the superblock is corrupt, automatically retry with the backup sbTheodore Ts'o1-3/+8
E2fsck currently only retries with the backup superblock if the primary superblock is missing (e.g., overwritten with garbage). If the superblock is just corrupted enough that it looks like ext2/3/4 superblock, but it is corrupt enough that ext2fs_open2() returns an error, e2fsck stops without retrying.

2007-08-20Use sscanf instead of atoi when parsing e2fsck optionsTheodore Ts'o1-6/+31
atoi() does not check for errors so it shouldn't be used for human input. For example, if the user enters the command "e2fsck -C -n" and forgets that -C requires an argument, the -n will be used as the argument to -C, and not parsed as an option. When using sscanf(), this error case can be detected. Addresses-Debian-Bug: #435381 Signed-off-by: Bernd Schubert <bs@q-leap.de> Signed-off-by: "Theodore Ts'o" <tytso@mit.edu>

2007-06-18Don't write changes to the backup superblocks by defaultTheodore Ts'o1-9/+12
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.

2007-06-04Fix e2fsck's get_size logic so it will work with the Linux floppy driverTheodore Ts'o1-0/+36
The Linux floppy driver is a bit different from the other block device drivers, in that if the device has been opened with O_EXCL, it disallows another open(), even if the second open() does not have the O_EXCL flag. So this patch moves the call to ext2fs_get_device_size() so that if it returns EBUSY, e2fsck can close the filesystem, retry the device size, and then reopen it. This rather complicated approach is required since we need to know the blocksize of the filesystem before we can call ext2fs_get_device_size().

Thanks to Andreas Dilger for this idea.

What's happening is that when you run on battery, e2fsck will delay running the filesystem check, on the assumption that it is better to defer the check until some time in the future when your laptop is running on AC mains again. This deferral is not infinite, however; if the number of mounts exceeds twice the max mount counts, or if the interval between checks exceeds twice the check interval, e2fsck will force the check even though you are on battery.
