2012-10-26mkfs.ubifs: Improve error handling of is_contained()Marcus Prebble
The is_contained() function returns -1 if an error occurs when canonicalizing the output file path/root directory. This resulted in the confusing error message 'Error: The output file cannot be in the UBIFS root' when specifying a non-existent directory for the output. This patch changes the error handling to display a different error message for the case when is_contained() returns -1. Additionally it frees all memory allocated by is_contained().

2012-10-11mkfs.ubifs: rewrite path checkingArtem Bityutskiy
We use the 'in_path()' function to check whether the output image is withing the mkfs.ubifs root directory or not. However, this function is not correct and it fails for the following situation, as Marcus Prebble <marcus.prebble@axis.com> reports: 1. We have our root file-system mounted at / and want to build an image out of it. 2. We have tmpfs mounted at /tmp 3. We mount the root file-system under /tmp/newroot 4. We run mkfs.ubifs with -r /tmp/newroot -o /tmp/image And this fails. It fails because 'in_path()' misses this use-case. This patch re-implements the check completely. Now we use 'realpath()' to find canonical paths and just check that the output file is not under the root mkfs.ubifs directory.

2012-09-25ubiformat: fix failure on big partitions (>4Gio)Richard Genoud
The offset (which is 64bits when mtd-utils are not compile with WITHOUT_LARGEFILE) is calculated like that: offset = nb * size; But nb and size are int, so on 32bits platforms, there's a possible overflow. So, it should be replace with: offset = (off_t)nb * size; If WITHOUT_LARGEFILE is defined, there still be an overflow, but it's what we want, right ?

2012-08-23ubiattach: fail if kernel ignores max_beb_per1024Richard Genoud
If the kernel doesn't know the max_beb_per1024 parameter in the attach ioctl, but the call still succeeded ubi_attach and ubi_attach_mtd will return 1 instead of 0. In this case, the ubiattach command will detach the device and fail with an error message.

2012-08-23ubiattach: introduce max_beb_per1024 in UBI_IOCATTRichard Genoud
The ioctl UBI_IOCATT has been extended with max_beb_per1024 parameter. This parameter is used for adjusting the "maximum expected number of bad blocks per 1024 blocks" for each mtd device. The number of physical erase blocks (PEB) that UBI will reserve for bad block handling is now: whole_flash_chipset__PEB_number * max_beb_per1024 / 1024 This means that for a 4096 PEB NAND device with 3 MTD partitions: mtd0: 512 PEB mtd1: 1536 PEB mtd2: 2048 PEB the commands: ubiattach -m 0 -d 0 -b 20 /dev/ubi_ctrl ubiattach -m 1 -d 1 -b 20 /dev/ubi_ctrl ubiattach -m 2 -d 2 -b 20 /dev/ubi_ctrl will attach mtdx to UBIx and reserve: 80 PEB for bad block handling on UBI0 80 PEB for bad block handling on UBI1 80 PEB for bad block handling on UBI2 => for the whole device, 240 PEB will be reserved for bad block handling. This may seems a waste of space, but as far as the bad blocks can appear every where on a flash device, in the worst case scenario they can all appear in one MTD partition. So the maximum number of expected erase blocks given by the NAND manufacturer should be reserve on each MTD partition.

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.

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>

2012-02-14libmtd: 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.
