2012-08-03load_nandsim.sh: remove useless functionArtem Bityutskiy
We do not really need a separate complex function to check if nandsim is already loaded or not. Besides, it is safer to check /proc/mtd in case nandsim is compiled-in. Signed-off-by: Artem Bityutskiy <artem.bityutskiy@linux.intel.com>

2012-06-29mtd-utils: Check mtdoffset is not larger than mtd.size in case of a bad block.Tomer Barletz
mtdoffset is being tested against mtd.size in the outer two loops, but the third nested one does not test against it. In case of a bad block we'll try to access an out of bounds offset in the next MEMGETBADBLOCK ioctl, which will fail with EINVAL. In case mtdoffset is indeed larger than the partition size, we need to bail, since there are not enough "good" blocks to complete the write.

2012-04-02Makefile: fixup previous 'make clean' fixBrian Norris
Apparently, Makefile comments need to be made without indentation. Otherwise, they are printed out as shell commands. This fix prevents seeing this in your shell during 'make clean': $ make clean ... # findutils v4.1.x (RHEL 4) do not have '+' syntax ...

2012-03-12Makefile: fix "make clean" for old GNU findBrian Norris
findutils v4.1.x does not have the `-exec CMD {} +' syntax. We can just as easily use the `-exec CMD {} \;' syntax. However, it will launch a lot more `rm' processes, so we only use it if the first form fails with an error. This isn't a perfect solution (`find -exec +' can fail for other reasons) but it works well enough. This problem manifests itself in RHEL 4, findutils 4.1.20: $ make clean rm -f /XXX/mtd-utils/*.o /XXX/mtd-utils/ftl_format ... find: missing argument to `-exec' make: *** [clean] Error 1 Signed-off-by: Brian Norris <computersforpeace@gmail.com> Acked-by: Mike Frysinger <vapier@gentoo.org> Signed-off-by: Artem Bityutskiy <artem.bityutskiy@linux.intel.com>
2012-03-07mkfs.ubifs: do not ignore --max-leb-cnt when formatting an UBI volumeArtem Bityutskiy
When the output file is an UBI volume - mkfs.ubifs just sets --max-leb-cnt to the volume size and ignores the user-supplied --max-leb-cnt value, which is wrong. Let's set it to the volume size only if the user did not supply --max-leb-cnt. Signed-off-by: Artem Bityutskiy <artem.bityutskiy@linux.intel.com>
2012-02-29libmtd_legacy: don't open device in R/WBrian Norris
On legacy kernels with ROM devices, we can get mtdinfo errors like: libmtd: error!: cannot open "/dev/mtd4" error 13 (Permission denied) mtdinfo: error!: libmtd failed get MTD device 4 information error 13 (Permission denied) We don't need O_RDRW access for informational ioctls(), so make this O_RDONLY.

2012-02-29libmtd: perform device checking firstBrian Norris
If we don't check for the MTD before calling `legacy_get_dev_info1', we may get errors like: libmtd: MTD subsystem is old and does not support sysfs, so MTD character device nodes have to exist libmtd: error!: "/dev/mtd2" is not a character device mtdinfo: error!: libmtd failed get MTD device 2 information error 22 (Invalid argument) So reverse the order of these two checks.

2012-02-14libmtd: fix mtd_write() issues for large data-only writesBrian Norris
ioctl(MEMWRITE) is implemented with memdup_user(), and so it allocates kernel memory in contiguous regions. This limits its usefulness for large amounts of data, since contiguous kernel memory can become scarce. I have experienced "out of memory" problems with ubiformat, for instance, which writes in eraseblock-sized regions: ... ubiformat: flashing eraseblock 12 -- 72 % complete ubiformat: page allocation failure. order:8, mode:0xd0 Call Trace: [<8043fa7c>] dump_stack+0x8/0x34 [<8008c940>] __alloc_pages_nodemask+0x408/0x618 [<800bd748>] cache_alloc_refill+0x400/0x730 [<800bdbbc>] __kmalloc+0x144/0x154 [<8009cae4>] memdup_user+0x24/0x94 [<802d04e4>] mtd_ioctl+0xba8/0xbd0 [<802d0544>] mtd_unlocked_ioctl+0x38/0x5c [<800d43c0>] do_vfs_ioctl+0xa4/0x6e4 [<800d4a44>] sys_ioctl+0x44/0xa0 [<8000f95c>] stack_done+0x20/0x40 ... libmtd: error!: MEMWRITE ioctl failed for eraseblock 12 (mtd0) error 12 (Cannot allocate memory) ubiformat: error!: cannot write eraseblock 12 error 12 (Cannot allocate memory) This error can be mitigated for now by only using ioctl(MEMWRITE) when we need to write OOB data, since we can only do this in small transactions anyway. Then, data-only transactions (like those originating from ubiformat) can be carried out with write() calls. This issue can also be solved within the kernel ioctl(), but either way, this patch is still useful, since write() is more straightforward (and efficient?) than ioctl() for data-only writes.

2012-02-14libmtd: fix segmentation fault on lib->mtdBrian Norris
Legacy systems do not initialize lib->mtd, so we shouldn't perform strlen(lib->mtd); this produces a segmentation fault.

2012-02-14limbtd: implement mtd_dev_present for old kernelsArtem Bityutskiy
Implement the 'legacy_dev_present()' function which will check whether an MTD device is present by scanning the /proc/mtd file when the MTD subsystem does not support sysfs (the case for pre-2.6.30 kernels).

2012-02-02mtdinfo: fix `--all' for non-consecutive device numbersBrian Norris
When we have assigned non-consecutive device numbers to our MTD devices, then we run `mtdinfo --all', we get errors once mtdinfo tries to process the devices in the "hole". For instance, suppose that at boot time, we have one MTD (/dev/mtd0) then perform a sequence like the following: # modprobe mtdram # modprobe nandsim # rmmod mtdram Then at this point, we have should have devices 0 and 2 without 1. Then: # mtdinfo --all ... mtdinfo: error!: mtd1 does not correspond to any existing MTD device We add a check to first see if device is present, then continue to the next ID if it doesn't exist.

When we have assigned non-consecutive device numbers to our UBI devices, then we run `ubinfo --all', we get errors once ubinfo tries to process the devices in the "hole". For instance, suppose there are two UBI devices, /dev/ubi0 and /dev/ubi10; then, ubinfo will fail trying to open /dev/ubi1 with: ubinfo: error!: cannot get information about UBI device 1 error 2 (No such file or directory) This patch adds a check to first see if device is present, then continue to the next ID if it doesn't exist.

2011-12-12libmtd: allow write operations when MEMWRITE is not supportedBrian Norris
MEMWRITE is a recently introduced write interface for MTD; however, it is only supported on NAND flash. mtd-utils should fall back to old write methods when either ENOTTY or EOPNOTSUPP are returned. This is a showstopper when, for instance, using ubiformat on NOR, which don't have a mtd->write_oob interface (and thus don't support MEMWRITE): ubiformat: formatting eraseblock 2 -- 1 % complete libmtd: error!: MEMWRITE ioctl failed for eraseblock 2 (mtd3) error 122 (Operation not supported) Signed-off-by: Brian Norris <computersforpeace@gmail.com> Signed-off-by: Artem Bityutskiy <Artem.Bityutskiy@linux.intel.com>

2011-11-18mtdinfo: provide info when used without argumentsBrian Norris
If the user specifies neither a MTD argument nor the `-a' flag, we print a cryptic message; i.e., # mtdinfo libmtd: error!: cannot get information about "(null)" error 14 (Bad address) mtdinfo: error!: cannot get information about MTD device "(null)" error 14 (Bad address) This is a regression; previously, mtdinfo would give some short info about number of devices, etc. when used without arguments. To fix this, we revert commit d53c03b0989f8354a7e4dbb947a150fc7fe3f6d1 and call print_general_info() when no device is specified.

2011-09-19ubiformat: handle write errors correctlyArtem Bityutskiy
This issue was reported and analyzed by Anton Olofsson <anol.martinsson@gmail.com>: when ubiformat encounters a write error while flashing the UBI image (which may come from a file of from stdout), it correctly marks the faulty eraseblock as bad and skips it. However, it also incorrectly drops the data buffer which was supposed to be written, and reads next block of data. This patch fixes this issue - in case of a write error, we preserve the current data and write it to the next eraseblock, instead of dropping it.
