2011-04-01libmtd: fix OOB read and write interfacev1.4.4Artem Bityutskiy
When reading and writing OOB we specify the address as absolute offset from the beginning of the MTD device. This offset is basically an absolute page offset plus the OOB offset. And it does not have to be aligned to the min. I/O unit size (NAND page size). So fix the 'do_oob_op()' function and remove incorrect checking that the offset is page-aligned. This check leads to the following errors: libmtd: error!: unaligned address 2, mtd0 page size is 2048 But obviously, the intent was to write to offset 2 of the OOB area of the very first NAND page. Instead of that incorrect check, we should check that the OOB offset we write to is within the OOB size and the length is withing the OOB size. This patch adds such check.

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>

2010-09-23libfec: 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.

2010-09-01lib: fix libcrc32 generationArtem Bityutskiy
libcrc32.a was generated without external symbols: nm -g libcrc32.a shoed nothing. This patch fixes it to make libcrc32.a build to be the same as libmtd.a. Frankly, I do not know why this happened and why this patch fixes the issue, sorry for my ignorance. But this works. Signed-off-by: Artem Bityutskiy <Artem.Bityutskiy@nokia.com>
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. Fix this by re-naming mtd-utils' crc32 function to mtd_crc32. Reported-by: Jon Povey <Jon.Povey@racelogic.co.uk> Signed-off-by: Artem Bityutskiy <Artem.Bityutskiy@nokia.com>

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>

2010-07-13mtd-utils: move libmtd source files to lib/ subdirectoryKevin Cernekee
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. This patch only renames/deletes files and does not change the content. Also modify the build system and source code so that libmtd.a can be built from a "common" location (lib/). Statically link all utilities at the top level with libmtd.a . Minor changes to mkfs.ubifs to allow using the common crc32 implementation.
