2022-11-07misc-utils: flashcp: fix buffer overflowBrandon Maier
The DIFF_BLOCKS code requires that src and dest buffers be large enough to hold one MTD erasesize. This is because each loop operates on one eraseblock so that it can erase and write one whole sector. But the src and dest buffers are fixed at BUFSIZE, so on platforms where the MTD erasesize are larger then BUFSIZE it will overflow the buffers. Instead allocate the buffers dynamically so that they can be sized to fit the erasesize.

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.

With that writing out the first page to the file doesn't happen because size_left is calculated to 0x100000000 - 0 = 0x100000000 which is then truncated to 32bit and becomes zero.

In commit a888044525, various header files that were added to the distribution tarball via EXTRA_DIST were instead added to the source lists of their respective programs instead. In the case of jffsX-utils, a missing escape for a new-line in the source list caused the include/linux/jffs2.h header to not be packged in the release tarball. This went undiscovered, as the system on which the release tarball was built, had the same header installed installed in the system include directory, so a `make distcheck` succeeded.

2021-10-13mtd-tests: Read and write pages during speed testsMiquel Raynal
The speed test does reads and writes of different sizes: - eraseblock - page - two pages At least this is the theory because, as opposed to the legacy kernel module doing the same measurement, the userspace tool uses the subpage size (hence accessing the same page 4, 8 or 16 times depending on the subpage setting). Of course if the controller does not support subpages, this issue is not visible. Use mtd.min_io_size instead for non-NOR devices in order to get the right bandwidth (at least one that fits the logs).

2020-11-29mtd-utils: ubihealthd: this tool does not depend on UBIFSJuergen Borleis
The "need_getrandom" check and result is used only for the "ubihealthd". This tool is very important to have it around at run-time, while the corresponding "mkfs.ubifs" tool is still optional (think about offline generated ubifs images). Since compiling "mkfs.ubifs" adds more dependencies (various shared libraries), buildsystems for embedded devices will add these shared libraries to the root filesystem even if "mkfs.ubifs" isn't used or installed. Thus, handling both tools independently makes sense. The previous behavior is kept, e.g. if UBIFS support is enabled, it enables "ubihealthd" as well.

2020-10-18mtd-utils: Add nandflipbits toolBoris Brezillon
The nandflipbits tool is intended to be used when one need to flip one or several specific bits on a NAND media. It can be useful to manually recover from an unexpected bit flip on a flash device, though the main purpose of this tool is to provide a way to test ECC algorithms robustness. One typical example I used this tool for is testing HW ECC engines behavior when bitflips occur in an erased page: most HW engines do not correctly handle this case, because, most of the time, ECC bits generated for an empty page are not all 1s, and, empty page detection embedded in such engines is only validating that all bits are set to 1s (which is not true when a bit-flip has occurred). Another use of this tool is replacing nandbiterrs test which absolutely do not work with MLC-like chips because of the rewriting of the pages in raw mode to toggle ones into zeroes.
