2010-09-23mkfs.ubifs: do not override root inode permissionsArtem Bityutskiy
When mkfs.ubifs is used with -r dir, it does not make the root UBIFS inode uid/gid/permissions to be equivalent to dir's permissions, but it makes root inode permissions to be equivalent to uid = git = 0 (root) and permissions = u+rwx go+rx. Unfortunately, we cannot simply fix this bug, because mkfs.ubifs is already used in production. Thus, we have introduce --squash-rino-perm option which is the default and it preserves the old mkfs.ubifs behavior. We also introduce --nosquash-rino-perm option which fixes mkfs.ubifs behavior. If none of these options is used, we print a warning. The plan is to make everyone use one of these options, then make --nosquash-rino-perm to be the default and remove the warning, and then eventually deprecate and remove both options.

2010-09-01rename crc32 to mtd_crc32Artem Bityutskiy
Because of namespace collisions mkfs.ubifs uses crc32() implementation from /lib/libz.so.1, which generates incompatible CRC and later on the kernel reports many CRC errors.

2010-07-26libmtd: add OOB read and write interfacesArtem Bityutskiy
This patch is based on Kevin Cernekee's patch posted to the MTD mailing list. It adds 'mtd_read_oob()' and 'mtd_write_oob()' interfaces support. The interfaces use MEMREADOOB64/MEMWRITEOOB64 MTD ioctls if possible, and fall-back to MEMREADOOB/MEMWRITEOOB if the 64-bit versions are not supported. The information about ioctls support is then cashed in 'offs64_ioctls' libmtd flag. Signed-off-by: Artem Bityutskiy <Artem.Bityutskiy@nokia.com>
2010-07-26libmtd: support MEMERASE64Artem Bityutskiy
This patch is base on Kevin Cernekee's patch posted to the MTD mailing list. It adds MEMERASE64 support to the 'mtd_erase()' call. Now it first tries to use MEMERASE64, and if that is not supported, falls back to the old MEMERASE ioctl. This patch also introduces an 'offs64_ioctl' flag to the libmtd descriptor. However, we cannot initialize it in 'libmtd_open()', because we need an MTD device node, which we do not have in 'libmtd_open()'. Thus, we firs mark this flag as "uninitialized", and at the first invocation of 'mtd_erase()' we initialize it. This also means that we have to pass the limbtd descriptor to 'mtd_erase()', to save the flag value. This, in turn, requires tweaking 'mtd_erase()' users. This is not very nice, but good enough so far. Signed-off-by: Artem Bityutskiy <Artem.Bityutskiy@nokia.com>

2010-07-21nanddump: add "forcebinary" flagBrian Norris
Restrict binary dumping so that by default, binary garbage is not printed directly to a terminal.

2010-07-21nanddump: add canonical (hex+ascii) flagBrian Norris

Source files for libmtd, crc32, and fec are scattered throughout the tree. Move them to a central location so they can be built into a common "libmtd.a" library used by all mtd-utils programs.
