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.

2017-02-21mtd-utils: Support jffs2 flash-erase for large OOB (>32b)Manikandan Ramachandran
"flash_erase" fails on nand flash with JFFS2 that has OOB size greater than 32 bytes. "flash_erase" uses "MEMGETOOSEL" to determine OOB size. This ioctl call is obsolete and returns error if OOB size is more than 32 bytes. This patch fixes this issue by using "mtd_write" to update clean-marker instead of mtd_oob_write. This fix is based on the discussion: http://lists.infradead.org/pipermail/linux-mtd/2011-September/037958.html. Signed-off-by: David Oberhollenzer <david.oberhollenzer@sigma-star.at>
2017-02-21ubi: tests: Speedup io_paral by using rand_r()Richard Weinberger
rand() is not thread safe, but glibc seems to use a shared state which is protected by a mutex. io_paral spawns a few threads and they call rand() more or less in parallel, which causes heavy lock contention. That makes the test extremely slow on some setups.

UDEV_SETTLE_HACK addresses a problem which does no longer exist on Linux. These days we have devtmpfs. New devices will automatically created on the kernel side and user space has no longer to wait for udev. As udev has a hard dependency on devtmpfs we can depend on it too. People which don't use udev nor plain devtmpfs are anyways on their own. Android, I'm looking at you...

2017-02-20mtd-utils: Fix format specifier definitions for off_t and loff_t.Torsten Fleischer
On 32bit systems (e.g. ARM) the size of off_t can be 4 byte and the size of loff_t 8 byte. This causes compiler warnings like the following: flash_erase.c: In function 'show_progress': flash_erase.c:56:22: warning: format '%llx' expects argument of type 'long long unsigned int', but argument 3 has type 'off_t {aka long int}' [-Wformat=] bareverbose(!quiet, "\rErasing %d Kibyte @ %"PRIxoff_t" -- %2i %% complete ", and an output like this: ~# flash_erase /dev/mtd2 0 1 Erasing 64 Kibyte @ 6400000000 -- 0 % complete ~# Since the size of off_t and loff_t can differ from each other, the printf format specifier should be determined separately for both. Further the format specifiers should be based directly on the size of the particular data type.

2016-12-22mtd-utils: Add configure switches to disable jffsX or ubifs toolsDavid Oberhollenzer
For some applications, like building a root filesystem for an embedded device, it may be desireable to only build and install a subset of the mtd-utils. This can be done throught the targets of the generated Makefile and hand picking executables, however the jffsX and ubifs utilities have external build dependencies that may not be needed. This patch adds configure switches to disable building the jffsX and ubifs utilities. Their respective build dependencies (zlib, lzo, uuid) are only requested if the tools are being built.

2016-12-13Fix packaging of unit test filesDavid Oberhollenzer
Previously, the unit test sysfs mock files and headers were not added to the distribution packag. Not packaging the header leads to compilation of the unit tests failing. Not packaging the stub files caueses the unit tests themselves to fail. This patch explicitly adds the header and sysfs mock files to the distribution target, allowing the unit tests to be used outside the git tree.

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. This includes: - libuib.a & libubigen.a used by the ubi utilities - libscan.a currently only used by ubiformat - libiniparser.a used by ubinize Signed-off-by: David Oberhollenzer <david.oberhollenzer@sigma-star.at>

This patch moves the remaining 3 functions from ubiutils-common.{c,h} into libmtd common.{c,h}.
