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.

2009-08-24ubinize: fix 64-bit image sequence number confusionArtem Bityutskiy
UBI image sequence number which we store in EC headers is 32 bits, not 64-bits. I was confused when noticed that the 'image_seq' variable had type 'unsigned long long'. Turn it into a 'uint32_t' type. Signed-off-by: Artem Bityutskiy <Artem.Bityutskiy@nokia.com>
2009-08-24ubiformat: fix typo in the help outputArtem Bityutskiy
The UBI image sequence number is a 64-bit integer, not 32-bit integer. 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>

2009-08-11nandwrite: unified reading from standard input and from file - part 3Jehan Bing
Nandwrite tries to use lseek() when failing to write on a page. lseek() will fail when used on the standard input so nandwrite fails. This code replaces lseek with a buffer. When the data is read, it is put in a buffer (filebuf). This buffer is reset at each block boundary. So a "seek" just means reading from the beginning of the buffer. writebuf and oobreadbuf are now just pointers to locations in filebuf.

2009-08-11mkfs.ubifs: correct devtable increment handlingDaniel Neukomm
With the device table one can add /dev entries to the root file system image. The device table file contains among others the fields minor, start, increment and count. If there is an entry with minor=0 start=0 increment=32 and count=4 the mkfs.ubifs makes 128 device entries, with minor numbers from 0 to 127. The correct version makes 4 entries with minor number 0,32,64,96. /dev/mtd c 640 0 0 90 0 0 2 7 This gives 14 devices /dev/mtdXX instead of 7 devices. Due to this error mtd_debug info /dev/mtd3 delivers the information of /dev/mtd1 instead of.

$ help2man /usr/sbin/jffs2dump | man /dev/stdin currently creates badly formatted output like -b --bigendian image is big endian -l --littleendian image is little endian -c --content dump image contents -e fname --endianconvert=fname convert image endianness, output to file fname -r --recalc- This patch modifies the --help output for jffs2dump to be more suitable for help2man and thus makes it possible to easily create manual pages that stay up-to-date.

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>

It's already about 2 years since the "-d" option was declared deprecated. UBI utils have printed a warning about this. Now it is time to kill this option completely.

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>

2009-06-02libmts: 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.
