libmtd: don't print an error message for devices without ecc support

2018-09-20T09:27:01+00:00

The libmtd library tries to obtain the available OOB size via the sysfs with a fallback to the ECCGETLAYOUT ioctl. For some devices (e.g. plat-ram), the fallback path is always taken and prints an error message to stderr since the ioctl fails. This patch fixes the fallback path by suppressing the error message if errno is set to EOPNOTSUPP (i.e. the device simply doesn't support that).

libubi: add volume flags to ubi_mkvol_request

2018-06-28T08:21:51+00:00

Now that we have per-UBI volume flags (for instance for skipping CRC check when opening it) from the Linux header, let's add it to the ubi_mkvol_request in libubi and assign the flags to ubi_mkvol_req from the Linux header from ubi_mkvol.

Revert "Return correct error number in ubi_get_vol_info1"

2018-06-09T16:09:39+00:00

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 Signed-off-by: David Oberhollenzer

libmtd: Add support to access OOB available size

2018-04-10T13:38:56+00:00

This patch exposes OOB available size to user. Then user can use OOB free area according to OOB available size. Steps to get OOB available size: First, access /sys/class/mtd/mtdX/oobavail. If not exist, then try to get ecc layout by ioctl "ECCGETLAYOUT". If none of them work, set OOB available size to 0. Signed-off-by: Xiaolei Li Signed-off-by: David Oberhollenzer
