2010-09-24nandwrite: add --skipbad to write bad blocksMike Frysinger
Sometimes dumping bad blocks is useful, like when the block isn't actually bad but the OOB layout isn't what the kernel is expecting or is otherwise screwed up. The --skipbad option allows just that.

2010-09-24mkfs.ubifs: Fix --squash-rino-perm / --nosquash-rino-permKevin Cernekee
This addresses a couple of issues: 1) Code was only allowing these options if --root was NOT specified (the opposite of the documented usage) 2) -q / -Q short options did not work 3) Spacing fixes in the error/warning strings Signed-off-by: Kevin Cernekee <cernekee@gmail.com> Signed-off-by: Artem Bityutskiy <Artem.Bityutskiy@nokia.com>
2010-09-23libfec: fix up pointer warnings in fec magic computationMike Frysinger
The current fec code casts a pointer to an int which causes warnings on 64bit systems. So create a macro for the duplicate/complicated magic computation, and add an unsigned long cast in it to fix the original problem.

2010-09-23mtd-utils: compr: drop unused model argumentMike Frysinger
The jffs2 compression framework provides a "model" argument when compressing and decompressing, but the caller always passes in NULL and the callees never use it. So punt this useless overhead.

2010-09-23mtd-utils: clean up zlib.h usage a bitMike Frysinger
Hide zlib's crc32 in compr_zlib.c and mkfs.ubifs/compr.c. jffs2reader.c and mkfs.jffs2.c don't actually use zlib, so punt the include from the file. mkfs.jffs2.c is implicitly using crc32 from zlib.h instead of the local mtd_crc32, so fix the local usage. otherwise we get warnings about undefined crc32 because the file was redirecting the prototype.

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.

2010-07-26libmtd: 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
Added the "-c" or "--canonicalprint" flag (modelled off 'hexdump -C') so that users can choose to print ASCII output next to the prettyprint output.
