2018-06-28UBI: update ubi-user.h and ubi-media.hQuentin Schulz
Update both header files to add support for flag specifying whether to skip the CRC check for static UBI volumes. Taken from the kernel headers. Some users of static UBI volumes implement their own integrity check, thus making the volume CRC check done at open time useless. For instance, this is the case when one use the ubiblock + dm-verity + squashfs combination, where dm-verity already checks integrity of the block device but this time at the block granularity instead of verifying the whole volume. Skipping this test drastically improves the boot-time.

2018-06-18Add lsmtd programDavid Oberhollenzer
This patch adds a program called "lsmtd". The program produces a pretty printed list of the hierarchy of UBI and MTD devices on a system. It tries to imitate the lsblk program from util-linux as closely as possible. A number of command line switches are available to fine tune what information should be exposed and in what output format. The goal is to have a simple way of displaying the complete MTD stack on a system in a human readable form instead of piecing details together from proc files and various UBI utilities.

2018-06-14mkfs.ubifs: Implement selinux labelling support in mkfs.ubifs.Ritesh Harjani
This implements/adds selinux labelling support to mkfs.ubifs utility. It adds an extra option in configure to enable selinux labelling support and then finally in mkfs.ubifs adds an extra option to pass the file_contexts which is looked up for filesystem file labels. - Default behavior is kept without selinux so as to not break existing support where selinux library/headers may not be present. - If this is configured with --with-selinux then XATTR from the file_contexts(passed with --selinux option while mkfs.ubifs) will be taken and not from the host file's xattr. This is done to avoid the problem where the host OS may have selinux enabled and hence same xattr names will be present in both host filesystem files and from the --selinux=file passed. So the existing behavior is kept mutually exclusive and preference is given to selinux xattrs (if configured with --with-selinux).

2018-06-14mkfs.ubifs: add_xattr is not depending on host XATTR supportRitesh Harjani
add_xattr adds the xattr to the ubifs image and has nothing to do with host XATTR support. Now that we are adding support where selinux interfaces may use this API even when host OS(where ubi/ubifs image is being created) does not support XATTR -so remove it from WITHOUT_XATTR #ifdef.

2018-06-09Revert "Return correct error number in ubi_get_vol_info1"David Oberhollenzer
This reverts commit dede98ffb706676309488d7cc660f569548d5930. The original commit tried to fix a descrepancy between the implementation and the documentation by making the implementation comply. When making the change, it was overlooked, that ubinfo and ubirename were written against the implementation instead of the behaviour specified by the documentation. So were further internal functions like ubi_get_vol_info1_nm which further breaks ubirmvol. A report with an outline of a resulting problem can be read on the mailing list: http://lists.infradead.org/pipermail/linux-mtd/2018-June/081562.html From the report: steps to reproduce: have mtd-utils 2.0.1 or 2.0.2 0. make a bunch of ubi volumes in sequential order ubimkvol /dev/ubi0 -s 64KiB -N test1 ubimkvol /dev/ubi0 -s 64KiB -N test2 ubimkvol /dev/ubi0 -s 64KiB -N test3 ubimkvol /dev/ubi0 -s 64KiB -N test4 .. 1. delete the test1 volume, making a hole in the volume table ubirmvol /dev/ubi0 -N test1 2. try an affected tool (i.e. "ubirmvol /dev/ubi0 -N test4" ) |root at mr24:/# ubirmvol /dev/ubi0 -N test4 |ubirmvol: error!: cannot find UBI volume "test4" | error 19 (No such device) or "ubinfo -a" | root at mr24:/# ubinfo -a | UBI version: 1 | Count of UBI devices: 1 | UBI control device major/minor: 10:59 | Present UBI devices: ubi0 | | ubi0 | Volumes count: 11 | Logical eraseblock size: 15872 bytes, 15.5 KiB | Total amount of logical eraseblocks: 1952 (30982144 bytes, 29.5 MiB) | Amount of available logical eraseblocks: 75 (1190400 bytes, 1.1 MiB) | Maximum count of volumes 92 | Count of bad physical eraseblocks: 0 | Count of reserved physical eraseblocks: 40 | Current maximum erase counter value: 984 | Minimum input/output unit size: 512 bytes | Character device major/minor: 251:0 | ubinfo: error!: libubi failed to probe volume 5 on ubi0 | error 19 (No such device) | Present volumes: 0, 1, 2, 3, 4root at mr24:/# Reported-by: Christian Lamparter <chunkeey@gmail.com> Signed-off-by: David Oberhollenzer <david.oberhollenzer@sigma-star.at>

2017-11-22mtd: tests: Fix check on ebcnt in nandpagetestPaul HENRYS
If the number of erase blocks to use is not specified, ebcnt originally set to -1 leads the program to exit with: "Cannot run with less than two blocks." If the number of erase blocks to use is not specified and thus ebcnt is equal to -1, the expected behaviour is to perform the test on all the erase blocks of the mtd partition.

2017-11-03ubi-utils: ubicrc32: process command line arguments firstDavid Oberhollenzer
When a command line option is used (e.g. --version), the tool tries to open it as a file first, then *uppon success* attempts to process the command line options (including what it assumed to be an input file) which is obviously broken.

2017-11-03Enable further warning flags, address new warningsDavid Oberhollenzer
mtd_debug: Remove a duplicate if case. MTD_CAP_NANDFLASH has only one flag set (MTD_WRITEABLE). Directly below, we had a check for MTD_WRITEABLE in the else branch which can't possible ever have triggered. Checking for MTD_WRITEABLE in addition to the CAP constants was probably not intended anyway, given the check for the individual flags if all else fails. integck: We already established that "r" is less than the number of elements in the list, so the loop condition doesn't need to check if w is NULL in addition. At least this way, the compiler "gets" that w cannot be NULL below and doesn't issue warnings. Signed-off-by: David Oberhollenzer <david.oberhollenzer@sigma-star.at>

2017-11-02Mark or fix switch cases that fall throughDavid Oberhollenzer
Now that C++17 introduced a special fallthrough keyword for explicitly tagging switch cases that are supposed to fall through, newer gcc versions also implement a feature request from 2002 to warn about maybe unwanted fall-throughs in switch cases in other languages (like C). For C code, we can either add a gcc specific attribute at the end of the switch case, or use a special comment that gcc checks for, indicating that the fall-through behaviour is indeed intended. This patch adds a "/* fall-through */" comment at the end of various case blocks to silence gcc warnings and in some cases a break, where fall-through was probably not intended. Signed-off-by: David Oberhollenzer <david.oberhollenzer@sigma-star.at>
2017-11-02Add no-return attribute to usage() style functionsDavid Oberhollenzer
A common pattern in command line processing is having a usage() function that prints out how to use the command line options and then terminates. The function is typically used inside a switch block for command line options like `-h' or unknown options. In a lot of places, the break keyword is omitted, because the function exits anyway. However, this triggers gcc warnings about implicit fall-through. Rather than adding a phony "/* fall-through */" this patch flags the usage() style function with a gcc attribute, indicating that they do not return and removes further superfluous break statements.

2017-08-24mtd-utils: tests: Avoid using less than two blocks in nandpagetestMiquel Raynal
Forbid the use of less than 2 eraseblocks in nandpagetest. It is obvious that the test cannot run on zero block, but it cannot run on only one block neither. The reason is: get_first_and_last_block() will return the same id for both the first and the last blocks. In erasecrosstest(), the logic is: - erase/write/read/verify first block - erase/write again first block - erase *last* block - read/verify first block When using only one block, 'first' refers to the same block as 'last', leading to erasing the block before reading it.

2017-07-03mtd-utils: tests: Add Erased Pages Bit Flip TestHarpreet Eli Sangha
Bit flip detection for written and erased pages tend to have different implementations. Where written pages are detected and corrected using ECC, erased pages are typically detected by ensuring that the number of zeros is less than a specified threshold. As such, it's necessary to have the 'nandbiterrs' test support the testing of written and erased pages. Bit flips in erased pages are emulated by rewriting the page in raw mode, to prevent the use of ECC.
