2013-03-11integck.c: Fix buffer overflow in save_fileElie De Brauwer
In the problem above I've spend several hours waiting for the issue to appear, only to had the 'luck' that it was found in a file whose name was 256 bytes in length, resulting in the write to fail. Closer examination showed that the buffer to store the path was 256 bytes in length, but this buffer also includes /tmp and the read/write suffix and should be able to contain a filename which is up to 255 bytes (NAME_MAX in linux/limits.h) in size which is a bad fit. So that array is modified to FILENAME_MAX (stdio_lim.h) and some checking is added to truncate the filename should it cause an overflow. The following log shows the first patch in action (see the correct seed), and shows why this third patch is needed: <quote> integck:     File Data: integck:         Offset: 0  Size: 1  Seed: 5008310  R.Off: 0 integck:     1 writes integck:     ============================================ integck:     Write Info: integck:         Offset: 0  Size: 1  Seed: 5008310  R.Off: 0 integck:         Offset: 0  Size: 1  Seed: 8246352  R.Off: 0 integck:         Offset: 0  Size: 1  Seed: 5078796  R.Off: 0 integck:         Offset: 0  Size: 1  Seed: 2267087  R.Off: 0 integck:         Offset: 0  Size: 1  Seed: 3602680  R.Off: 0 integck:     5 writes or truncations integck:     ============================================ integck: Saving /tmp/yqcnfygfitaatyeyvffrguegcdttamcnyhowhgieljfuxfipiljsjcbluaeaghwyinkggommsbwnmvekihgnwgiibccpbwfrpxuxwkmnyghnutrudienngxwgorudbskedaaekiuiyqksfazrwzfwbfhzjjqoiulebtlpbfiuffmsnguqkjzqjqizimsmhbqqagaebjdhqwmzdxghiavtcxubegawlgtvstuqurkurpnrckjfkgostdtpg.integ.sav.readn integck: error!: condition 'w_fd != -1' failed in save_file() at integck.c:1445 integck: error 36 (File name too long) </quote> Signed-off-by: Elie De Brauwer <eliedebrauwer@gmail.com> Signed-off-by: Artem Bityutskiy <artem.bityutskiy@linux.intel.com>
2013-03-11integck.c: rework file_check_data to immediately dump the buffer containing ↵Elie De Brauwer
the errors See my problem description int the previous commit, the point is that integck in file_check_data reads a buffer, and then checks if the data is correct,  it will do a seek(0), and reread from the same fd. The point is that in the scenario I observed integck failed (due to a buffer mismatch) but the it saved (and what was in flash) was actually correct. So I modified this function to dump the buffers to stderr at the moment an error is found.

Clearly it is not there (which is already extremely confusing). The point is that file_write_info first updates the raw_write, then verifies the data (passing the new write) and only after that updates the write structure. But in file_check_data only the newly written data is verified (passed as an argument) whilst the save_file() function to dump the file uses the raw_writes to recreate the written data (while raw_writes is only updated after after this check would have succeeded). Several lines to say that in this patch the verify only gets called _after_ the datastructures are updated.

2013-03-11flash_otp_write: fix writing to NAND in presence of partial readsUwe Kleine-König
When doing something like: { printf "\xff"; printf "\xfe"; } | flash_otp_write -u /dev/mtd0 0 flash_otp_write might see only a single byte when reading from stdin for the first tim. In this case (and without this patch) it pads to $writesize with '\xff's and writes that out. In the next iteration it reads the 2nd byte, pads and writes again. So the 2nd byte is written to offset $writesize instead of 1. Signed-off-by: Uwe Kleine-König <u.kleine-koenig@pengutronix.de> Signed-off-by: Artem Bityutskiy <artem.bityutskiy@linux.intel.com>

2012-12-03ubi-tests: fix pthreads linkingBrian Norris
Technically, '-l' linker options should be included only after the objects which must link to the library. So when we include '-lpthread' in the LDFLAGS variable, it gets placed too early (i.e., before the io_paral.o object), and so the pthread linkage never occurs. The following error probably only shows up with linkers that don't link pthreads by default. $ make tests V=1 ... gcc -I../../ubi-utils//include -I ../../include -lpthread -Wall -Wextra -Wwrite-strings -Wno-sign-compare -ffunction-sections -fdata-sections -Wl,--gc-sections -g -o /home/norris/git/mtd-utils/tests/ubi-tests/io_paral /home/norris/git/mtd-utils/tests/ubi-tests/io_paral.o /home/norris/git/mtd-utils/tests/ubi-tests/helpers.o libubi.a /home/norris/git/mtd-utils/tests/ubi-tests/io_paral.o: In function `main': /home/norris/git/mtd-utils/tests/ubi-tests/io_paral.c:287: undefined reference to `pthread_create' /home/norris/git/mtd-utils/tests/ubi-tests/io_paral.c:295: undefined reference to `pthread_create' /home/norris/git/mtd-utils/tests/ubi-tests/io_paral.c:303: undefined reference to `pthread_join' collect2: ld returned 1 exit status make[2]: *** [/home/norris/git/mtd-utils/tests/ubi-tests/io_paral] Error 1 ... $ ld --version GNU ld (GNU Binutils for Ubuntu) 2.22 ... $ gcc --version gcc (Ubuntu/Linaro 4.6.3-1ubuntu5) 4.6.3 ...

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: 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.
