2009-06-30ubiformat: allow zero erase counterArtem Bityutskiy
This patch fixes the following issue: $ ubiformat /dev/mtd2 -e 0 ubiformat: error!: bad erase counter value: "0" Signed-off-by: Artem Bityutskiy <Artem.Bityutskiy@nokia.com>
2009-06-08libubi: fix wrong size calculation with sizes > 4GiBDetlef Bardtholdt

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.

2009-05-11ubi-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
Rename 'struct mtd_info' to 'struct mtd_dev_info' to reflect the fact that it provides information about a specific MTD device. Also, this is more consistent with libubi. Signed-off-by: Artem Bityutskiy <Artem.Bityutskiy@nokia.com>

2009-04-20ubinfo: handle -d correctlyArtem Bityutskiy
Fix ubinfo utility and make it handle -d parameter correctly. Without this patch it simple refuses working with -d. Signed-off-by: Artem Bityutskiy <Artem.Bityutskiy@nokia.com>
2009-04-18ubiformat: increase version to 1.2Artem 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. The callers should find a better place. This patch improves code readability and prepares for further changes. Signed-off-by: Artem Bityutskiy <Artem.Bityutskiy@nokia.com>

2009-03-31ubi-utils: tweak vpath handlingMike Frysinger

2009-02-11I have here a mtd part which is 3 GiB with a flash page size of 256KiB.linux-mtd-owner@lists.infradead.org
The 2GiB limit is at erase block 8192. In mtd_is_bad() the computation for the MEMGETBADBLOCK ioctl() looks like the following: | seek = eb * mtd->eb_size; with both eb and mtd->eb_size being a signed int results in seek being a signed result. The _FILE_OFFSET_BITS=64 define is required to switch off_t from 32bit to 64bit an 32bit systems. This is required in order to keep using lseek() as lseek64 on 32bit system. Without this change lseek() in mtd_read() is called with a 32bit value with most significat bit set and the kernel performs a sign extension for the 64bit value which is used in the mtd layer. The last change also changes the size of the parameter which is passed to the MEMGETBADBLOCK ioctl() from 32 to 64bit. The counter part in kernel is also defined as loff_t which is of type __kernel_loff_t and this is "long long". So this must have been broken for a while unless I missed something.

2009-01-20ubiupdatevol: fix -t parameterSebastian Andrzej Siewior
The execution of |./ubiupdatevol /dev/ubi0 -t will fail because 'argv[optind + 1]' is undefined and the later executed 'strcmp(args.img, "-")' will segfault.
