2010-01-15ubiformat: be consistent with sequence numbersArtem Bityutskiy
This commit fixes a stupid an nasty bug. When we flash an UBI image, we do not change its sequence numbers. But when we format the rest of the PEBs (beyond the flashed image), we use a random (or specified via cmdline) sequence number. As a result, we have a broken flash format and UBI refuses it, because half of it has one sequence number, another half has a different one. What we have to do instead, we have to substitute image's sequence number with ours.

2010-01-15ubiformat: always initialize seq numberArtem Bityutskiy
For some reasons sequence number was set to 0 in some case, which is wrong. Signed-off-by: Artem Bityutskiy <Artem.Bityutskiy@nokia.com>

2009-11-26ubiformat: fix --erase-counter handlingArtem Bityutskiy
The --erase-counter option did not work and this was reproted by Darwin Rambo <drambo@broadcom.com> Signed-off-by: Artem Bityutskiy <Artem.Bityutskiy@nokia.com>
2009-09-28ubinize/ubiformat: improve random number seedingArtem Bityutskiy
Add current time to the PID to improve the pseudo-random number generator seeding. Also, use 'rand()' instead of 'random()', because 'srand()' is for 'rand()'. Signed-off-by: Artem Bityutskiy <Artem.Bityutskiy@nokia.com>
2009-09-28ubiformat/ubinize: Don't randomize 0xFFFFFFFF sequence numberMichael Roth
args.image_seq is of type uint32_t and was initialized to -1 which becomes 0xFFFFFFFF in this case. Later the value -1 was used as a flag that args.image_seq should be replaced with a randomized value. With the option --image-seq (-Q) a user could provide any sequence number at will. But when the user provided sequence number was 0xFFFFFFFF this was understood effectivly as -1 and got overridden by a randomized sequence number. So this patch change the programm flow to respect the principle of least surprise and never use a randomized sequence number when the user provide one at own will.

2009-09-28ubiformat/ubinize: fix more 64-bit image sequence number confusionMichael Roth
The sequence number is only 32 bit as the strtoul() function. Signed-off-by: Michael Roth <mroth@nessie.de> Signed-off-by: Artem Bityutskiy <Artem.Bityutskiy@nokia.com>
2009-08-24ubiformat: add image sequence supportArtem Bityutskiy
Similarly to ubinize, add image sequence number support. Signed-off-by: Artem Bityutskiy <Artem.Bityutskiy@nokia.com>
2009-08-24mkfs.ubifs: do not forget to torture PEBArtem Bityutskiy
We added PEB torturing for the case when we fail during flashing an image, but forgot to add it for the case when we are formating the flash. Add the forgottent torturing call. Signed-off-by: Artem Bityutskiy <Artem.Bityutskiy@nokia.com>

2009-07-26ubinize: add sequence number supportArtem Bityutskiy
UBI now supports the image sequence number feature which prevents UBI from mistakingly accepting half-written images, if the image was written on top of an older image. Support this feature in ubinize and make it pick a random number for the UBI image sequence number. Signed-off-by: Artem Bityutskiy <Artem.Bityutskiy@nokia.com>
2009-07-26ubiformat: version 1.4Artem Bityutskiy
Increase ubiformat version to reflect the fact that now we torture PEBs before marking them as bad. Signed-off-by: Artem Bityutskiy <Artem.Bityutskiy@nokia.com>
2009-07-26ubiformat: make badblocks output less confusingArtem Bityutskiy
When ubiformat prints something like ubiformat: bad eraseblocks: 1400 it looks like there are 1400 bad eraseblock, although there is only one with number 1400. Fix this but turning the print into ubiformat: 1 bad eraseblock found, numbers: 1400 Signed-off-by: Artem Bityutskiy <Artem.Bityutskiy@nokia.com>
2009-07-26ubiformat: nicify error outputArtem Bityutskiy
Do not print extra newline if write fails, because mtd_write prints a message and adds newline. Signed-off-by: Artem Bityutskiy <Artem.Bityutskiy@nokia.com>
2009-07-26ubiformat: minor printing clean-upArtem Bityutskiy
When a PEB is marked as bad while we are formatting, ubiformat prints 99% done at the end. Make it print 100% done instead. Signed-off-by: Artem Bityutskiy <Artem.Bityutskiy@nokia.com>
2009-07-26ubiformat: torture eraseblocks on write errorsArtem Bityutskiy
When fail to write to PEBs, and the error is EIO, torture the PEB before marking it as bad. Basically, the code is copied from the kernel UBI. 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>
2009-04-20libmtd: rename mtd_get_infoArtem Bityutskiy
Rename 'mtd_get_info()' into 'mtd_get_dev_info()' to be consistent to libubi. Signed-off-by: Artem Bityutskiy <Artem.Bityutskiy@nokia.com>

The previous patch fixed a nasty bug, so it is nice to increase program version to reflect that. Signed-off-by: Artem Bityutskiy <Artem.Bityutskiy@nokia.com>
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>
