And it is very careful > about error codes - only EIO code is considered as a reason to mark an > eraseblock as bad. Fixed broken behavior in case of write failure. More specifically: - Only try to mark a block bad if the errors are EIO. Other errors will abort the tool. - Also abort the tool if the marking fails instead of ignoring it.

2009-06-09nandwrite: return error if failure when reading from standard inputJehan Bing
Fix nandwrite to return EXIT_FAILURE in case of error when using the standard input instead of a file for input. Signed-off-by: Jehan Bing <jehan@orb.com> Signed-off-by: Artem Bityutskiy <Artem.Bityutskiy@nokia.com>
2009-06-08libubi: fix wrong size calculation with sizes > 4GiBDetlef Bardtholdt
This fixes the handling of total_bytes, avail_bytes and rsvd_bytes. The result of the multiplication must be 64 Bit. Signed-off-by: Detlef Bardtholdt <bardtholdt.detlef@ng-litef.de> Signed-off-by: David Woodhouse <David.Woodhouse@intel.com>
2009-06-08nandwrite: amend loop conditionJehan Bing
If the file contains only a few bytes in the last page and the --oob option is selected, the loop may exit early (readlen < meminfo.oobsize). Most of the time it will still work though because the code tries to read the whole OOB in one chunk.

2009-06-02libmts: recognize pre-MTD-sysfs kernels betterArtem Bityutskiy
Not-so-old linux kernel like 2.6.29 do already have "/sys/class/mtd/mtdX" directories, while very old kernels do not. But in 2.6.29 these directories do not contain any information. Anyway, the logic in libmtd which checked whether the system supports sysfs was broken, because it assumed that old systems do not even have "/sys/class/mtd/" directory. Fix this problem by checking for "/sys/class/mtd/mtdX/name". If this is present - the system really has sysfs support. This patch also adds an extra print to libmtd.

2009-05-27mkfs.ubifs: use libubi to format UBI volumeCorentin Chary
libubi is now used to format directly UBI volume. Typing mkfs.ubifs /dev/ubi0_0 is now possible. dtypes should be ok as they are taken from UBIFS code. Signed-off-by: Corentin Chary <corentincj@iksaif.net> Signed-off-by: Artem Bityutskiy <Artem.Bityutskiy@nokia.com>

2009-05-11ubi-utils: fix memory corruptionsArtem Bityutskiy
This patch contains changes similar to the ones in the previous patch. Also, it changes all invocations of memset and makes sure the argument is 0, not '\0', because memset expects int, not char. Signed-off-by: Artem Bityutskiy <Artem.Bityutskiy@nokia.com>
2009-05-11libubi: fix multiple memory corruptionsCorentin Chary
The memset is obviously wrong, and valgrind tells use there are some uninitialised bytes used after read() Signed-off-by: Corentin Chary <corentincj@iksaif.net> Signed-off-by: Artem Bityutskiy <Artem.Bityutskiy@nokia.com>

2009-05-08libubi: do not use udevsettleArtem Bityutskiy
Not sure why, but udevsettle does not work when threads are used. In the io_paral test I experience the problem when udevsettle opens UBI volumes and prevents tests to open them (EBUSY is returned). Signed-off-by: Artem Bityutskiy <Artem.Bityutskiy@nokia.com>

2009-04-20libmtd: rename mtd_infoArtem Bityutskiy

2009-04-18ubiformat: fix segfault and messagesArtem Bityutskiy
ubiformat segfaults like this: ubiformat: mtd0 (NAND), size 134217728 bytes (128.0 MiB), 16384 eraseblocks of 16384 bytes (16.0 KiB), min. I/O size 512 bytes libscan: scanning eraseblock 8191 -- 100 % complete ubiformat: 8190 eraseblocks have valid erase counter, mean value is 9 ubiformat: 2 eraseblocks are supposedly empty ubiformat: warning!: VID header and data offsets on flash are 512 and 1024, which is different to calculated offsets 256 and 512 ubiformat: use new offsets 512 and 1024? (yes/no) no Segmentation fault The reason is that volume table size is calculated for 256/512 layout, and when user chooses 512/1024 - it is not re-calculated which leads to segfault in 'ubigen_write_layout_vol()'. This patch also fixes the message - in the above output new offsets are 256/512, not 512/1024. Also, this patch adds explicit printing of the selected positions.

2009-04-18libmtd: amend interfaceArtem Bityutskiy
Remove the fd field from the mtd information data structure, because libmtd does not really know the device node file name, and serves only as a place to save the descriptor.
