2023-11-20ubiattach: introduce need_resv_pool in UBI_IOCATTZhihao Cheng
The ioctl UBI_IOCATT has been extended with need_resv_pool parameter in [1]. This parameter is used for deciding whether to reserve PEBs for filling pool/wl_pool for target ubi device. This parameter will be effective when fastmap is enabled, which will slow down the frequency of updating fastmap by filling more free PEBs in pool/wl_pool. See details in [2].

If 'disable_fm' is set, ubi doesn't create new fastmap even the module param 'fm_autoconvert' is set, and existed old fastmap will be destroyed after attaching process. A simple test case in [2].

2023-05-30mtd-utils: Add new syntax to get devices by nameBrandon Maier
This introduces a new feature to the MTD command line utilities that allows MTD devices to be referenced by name instead of device node. For example this looks like: > # Display info for the MTD device with name "data" > mtdinfo mtd:data > # Copy file to MTD device with name "data" > flashcp /my/file mtd:data This follows the syntax supported by the kernel which allows MTD device's to be mounted by name[1]. Add the function mtd_find_dev_node() that accepts an MTD "identifier" and returns the MTD's device node. The function accepts a string starting with "mtd:" which it treats as the MTD's name. It then attempts to search for the MTD, and if found maps it back to the /dev/mtdX device node. If the string does not start with "mtd:", then assume it's the old style and refers directly to a MTD device node. The function is then hooked into existing tools like flashcp, mtdinfo, flash_unlock, etc. To load in the new MTD parsing code in a consistent way across programs.

2022-09-27libmtd: do not ignore non-zero eraseblock size when MTD_NO_ERASE is setEnrico Jorns
In 54d68799, mtd->eb_cnt was enforced to be '1' if MTD_NO_ERASE is set. This was done with the aim of preventing divisions by zero. However, even if MTD_NO_ERASE is set, mtd->eb_size (eraseblock size) can still be set to a non-zero value which would not cause a division by zero. Instead, enforcing an eraseblock count of '1' here even leads to inconsistent eraseblock counting in mtd-utils and lets for example a 'flash_erase' on an mtdnand device fail: | # flash_erase /dev/mtd0 0 0 | Erasing 32768 Kibyte @ 0 -- 0 % complete libmtd: error!: bad eraseblock number 255, mtd0 has 1 eraseblocks | flash_erase: error!: /dev/mtd0: MTD Erase entire chip failureTrying one by one each sector. | error 22 (Invalid argument) | Erasing 128 Kibyte @ 0 -- 0 % complete libmtd: error!: bad eraseblock number 1, mtd0 has 1 eraseblocks | flash_erase: error!: /dev/mtd0: MTD get bad block failed | error 22 (Invalid argument) Also mtdinfo would look inconsistent (eraseblock size vs amount): | # mtdinfo /dev/mtd0 | mtd0 | Name: mtdram test device | Type: ram | Eraseblock size: 131072 bytes, 128.0 KiB | Amount of eraseblocks: 1 (33554432 bytes, 32.0 MiB) | Minimum input/output unit size: 1 byte | Sub-page size: 1 byte | Character device major/minor: 90:0 | Bad blocks are allowed: false | Device is writable: true Fix this by enforcing mtd->eb_cnt to be '1' only when mtd->eb_size is actually zero and would lead to a division by zero otherwise.

2020-02-09mtd-utils: Fix "are we really at EOF" test logic in libubi read_dataDavid Oberhollenzer
The function reads file data into a buffer and then checks if we actually are at the end-of-file by trying to read one more byte. For whatever reason, the code uses an int instead of a char. It's not pretty but works. But again, this is something that every static analysis tool barks at. Further more, the error messages are inverted. "We aren't at EOF yet" is printed on failure and something like "read error %m" is printed on success. This patch fixes all of the above.

2018-09-20libmtd: don't print an error message for devices without ecc supportDavid Oberhollenzer
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).

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>

2017-03-22Return correct error number in ubi_get_vol_info1David Oberhollenzer
If the specified UBI device or volume does not exist, the function is supposed to set errno to ENODEV. This patch adds a check to ubi_get_vol_info1 to change the errno to ENODEV if vol_get_major cannot access the underlying sysfs file, so the function propperly returns that the device or volume does not exist, instead of failing with errno set to ENOENT.

2017-03-15Fix libmtd behaviour if MTD is not present on the systemDavid Oberhollenzer
The documentation of libmtd_open says, if it returns NULL and errno is zero, MTD is not present. However, the current version always returns a libmtd_t object. The function internally checks, if it can access the MTD sysfs files and, if not, sets a flag to use the procfs fallback. This patch adds an additional check to libmtd_open, to test if the MTD procfs file can be read and fails with errno cleared if it does not exist. Furhtermore, mtd_get_info is documented to fail with errno set to ENODEV if MTD is not present. First of all, this was broken in the original version. It was implemented to specification for the sysfs code path, but if MTD is not present, that won't be executed, because of the flag set by libmtd_open. This makes the check not only redundant, but masks an actual error (the sysfs paths suddenly not being readable anymore). The legacy path that was used if the sysfs files are not avaible fails with ENOENT if it cannot read the procfs file. With the above changes in addition, we don't have a libmtd_t object if neither sysfs nor procfs is readable, so this error status no longer makes sense. This patch removes the documentation on the ENODEV errno, and makes sure that mtd_get_info always returns with apropriate errno on failure.

2016-11-17Move ubi-utils libraries to common library locationDavid Oberhollenzer
Historically, the mtd-utils and ubi-utils were seperate packages. The ubi-utils were at some point merged into the mtd-utils. They first appeared in the release tar-ball in version 1.1.0 in their own sub-hirarchy with their own buildsystem, readme, documentation, etc. A lot of the duplicated stuff got centralized/removed over time. This patch further cleans up the directory hirarchy duplication by moving common libraries from the ubi-utils/ into the central lib/ and include/ directories in the top directory of the mtd-utils package.

2016-11-17Remove unused and broken mtd_write_img function from libmtdDavid Oberhollenzer
The function _tries_ to support short reads but doesn't adjust the pointer into the buffer. If a short read happens, we scrambles the flash contents. Interrupted reads aren't handled. Short or interrupted writes aren't handled at all. Either a write succeeds writing the entire buffer or the function gives up. During an attempt at fixing it, it was discovered, that no mtd-utils program uses this function. Furthermore, its highly specific nature makes it more of a "feature looking for use case".

2016-07-13libmtd: Fix return status in mtd_torture test functionDavid Oberhollenzer
This patch fixes the return status of the mtd_torture function in libmtd. The torture test function is currently only used by the ubiformat utility to check if a block is bad after a write fails (blocks are marked bad if the function returns an error status). However, the way the function was written, it ALWAYS returns an error value regardless of whether it failed or not.

2015-11-17libmtd: mtd_read: Take the buffer offset into account when readingMarcus Prebble
Assuming the read() call does not return zero and the result is less than len, the current implementation will overwrite the data already read in buf which doesn't seem correct. With this patch, subsequent calls to read() within the loop will now no longer overwrite the existing contents of buf.
