fs/common: add support for LZO and XZ compression methods

Add support for LZO and XZ compression methods to cpio, ext2, tar and ubifs filesystem targets. Signed-off-by: Gustavo Zacarias Signed-off-by: Peter Korsgaard

fs/ext2: bump journal overhead to 1300 blocks

2013-04-12T12:57:36+00:00

A quick test with a ~3.5MB ext4 filesystem shows that 1081 blocks isn't enough: tune2fs 1.42.7 (21-Jan-2013) Please run e2fsck on the filesystem. Creating journal inode: Journal size too big for filesystem. So bump it a bit. Overestimating the journal size is probably not really a big deal for the kind of systems using ext3/4 anyway.

fs/ext2: remove count- and time-based fsck

2013-04-12T12:45:47+00:00

Set the count- and time-based checks intervals to 0, thus effectively disabling automatic checks at boot (after a suggestion by Arnout). Signed-off-by: "Yann E. MORIN" Cc: Arnout Vandecappelle Cc: Thomas Petazzoni Acked-by: Arnout Vandecappelle (Essensium/Mind) Signed-off-by: Peter Korsgaard

fs/ext2: add support for ext2 rev0 and rev1

2013-04-12T12:43:22+00:00

Some bootloaders have a buggy ext2 support, and require ext2 rev1 instead of the traditional ext2 rev0 that genext2fs produces. tune2fs accepts only one '-O list' at a time, so we need to construct a list of -O options.

fs/ext2: add a symlink 'rootfs.ext#' -> 'rootfs.ext2'

fs/ext2: add ability to build ext3/4 too

2013-04-12T12:39:24+00:00

Use the host-e2fsprogs to tune2fs the generated rootfs.ext2 image, and upgrade it to either one of ext2, ext3 or ext4. Since calling tune2fs may require running e2fsck (tune2fs will warn to do so when certain FS options are changed), we systematically call e2fsck. This makes the code path simpler, and as a side-effect checks that genext2fs did not generate garbage. In turn, e2fsck will unconditionally add a UUID to the filesystem, which is bad for reproducibility, so we call tune2fs again to remove the UUID. This does not require checking the filesystem. To ensure compatibility of Buildroot's .config, leave ext2 as the default. Boards' .config can override this at will. Signed-off-by: "Yann E.

fs/ext2: enclose the ext2 options in if...endif

2013-04-12T12:39:04+00:00

Use a 'if...endif' construct instead of repeating the 'depends on' for each symbols. Signed-off-by: "Yann E. MORIN" Acked-by: Arnout Vandecappelle Acked-by: Thomas Petazzoni Signed-off-by: Peter Korsgaard

fs/common.mk: delay evaluation of variables

2013-01-20T19:53:29+00:00

This makes things easier to understand and more consistent with the pkg-infra. For example, it removes the need for '$$@' in the CMD variables of fs/*/*.mk. It also makes it possible to update the variables later, e.g. in the package override file. It also makes sure that the date will be recorded correctly in Yann E. Morin's patch that logs the MESSAGE macros to a file. The fs/*/*.mk must be updated as well because the '$@' shouldn't be quoted anymore in the CMD variables or the hooks. The $(eval ...) for the dependencies is redundant, because the $(ROOTFS_TARGET) variable is already eval'd. Note that it is only redundant if the evaluation of the uses of the variable is also delayed. Signed-off-by: Arnout Vandecappelle (Essensium/Mind) Signed-off-by: Peter Korsgaard

fs/ext2: remove redundant BR2_TARGET_ROOTFS_EXT2_SQUASH option

2011-01-14T10:15:28+00:00

The generic fs handling does a chmod -R 0:0 $(TARGET_DIR), so there's no need for a specific option to enforce this when making an ext2fs image. Signed-off-by: Peter Korsgaard

fs/ext2: don't enable by default

2011-01-14T09:12:23+00:00

It's pretty uncommon to use ext2fs on embedded systems, so don't enable it by default. Adjust defconfigs to match. Signed-off-by: Peter Korsgaard
