2010-10-12nanddump: fix initialization of bad blocks oob data bufferBaruch Siach
When dumping oob data of a bad block, initialize oobbuf with 0xff, instead of readbuf. This avoids bogus oob data on output. Signed-off-by: Baruch Siach <baruch@tkos.co.il> Acked-by: Mike Frysinger <vapier@gentoo.org> Signed-off-by: Artem Bityutskiy <Artem.Bityutskiy@nokia.com>

2010-10-02libmtd: make malloc failures fatalMike Frysinger
This converts libmtd to the common xalloc helpers and in doing so, makes memory allocation failures fatal rather than returning an error to the caller. I think this is acceptable behavior. Signed-off-by: Mike Frysinger <vapier@gentoo.org> Signed-off-by: Artem Bityutskiy <Artem.Bityutskiy@nokia.com>
2010-10-02sumtool/libfec: convert "()" to "(void)" in func defsMike Frysinger
Since these functions take no parameters, declare them as such. The subtle difference here is that gcc allows (without warning) people to accidentally call funcs declared with "()" with arguments. Using void makes sure that gcc will reject such typos at compile time. Signed-off-by: Mike Frysinger <vapier@gentoo.org> Signed-off-by: Artem Bityutskiy <Artem.Bityutskiy@nokia.com>

2010-10-01mtd-utils: xalloc: simplify/unify error messagesMike Frysinger
I'm not sure that if we actually are out of memory that declaring the failing allocation size is useful in the output. So use the same simple string in every error message to cut down on size (there will only be one copy of this at runtime). Size is a much more common concern than handling OOM issues which most likely aren't the fault of mtd-utils in the first place.

2010-09-27mtd-utils: unify flash_erase and flash_eraseallMike Frysinger
These have overlapping functionality, and while flash_eraseall supports newer 64bit ioctls, flash_erase does not. So rather than graft support onto flash_erase, merge the functionality of two into flash_erase so we only have to support one util from now on. A simple wrapper is provided to ease old flash_eraseall users into the new combined flash_erase util.

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.
