2016-11-17Add libmissingDavid Oberhollenzer
This patch adds a libmissing library to mtd-utils, containing implementations of functionality found in glibc but typically missing from embedded C libraries such as uclibc ot musl. For now, the library only contains stub implementations of the backtrace*() family of functions.

2016-11-17Unify version string printingDavid Oberhollenzer
When a program does sophisticated enough command line processing (i.e. getopt), make sure it responds to -V and --version. When a program prints a version string, make sure it uses the common_print_version macro to print out its name, that it is part of mtd-utils and the mtd-utils version from the build system in a fashion similar to common program packages like the GNU coreutils. When a program responds to -V/--version or -h/--help, make sure it reports success exit status.

2016-11-17Change build system to autotoolsRichard Weinberger
This patch is largely based on Richards original RFC. The major differences to the RFC patch are: - Add missing sumtools & mtdpart targets - Fix name of mkfs.jffs2 target - Add missing subdir-objects option for non-recursive make - Move all automake options to configure.ac - Add manpages to install target - Make XATTR & LZO support configurable - Install binaries to sbin directory like in the old build system - Install flash_erase wrapper script - Add files missing from distribution target Signed-off-by: David Oberhollenzer <david.oberhollenzer@sigma-star.at> Signed-off-by: Richard Weinberger <richard@nod.at>
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".

These functions have always been defined in sys/sysmacros.h under Linux C libraries. For some, including sys/types.h implicitly includes that as well, but glibc wants to deprecate that, and some others already have. Include the header explicitly for the funcs.

2015-05-28include/common.h: fix build against muslJörg Krause
Like uClibc version older than (not yet released) 0.9.34 musl does not have a rpmatch() implementation. uClibc defines both __UCLIBC__ and __GLIBC__.

An implementation of rpmatch() was backported to the 0.9.33 branch of uClibc. So the uClibc version check introduced in commit 50c9e11f7e (include/common.h: fix build against current uClibc) is not enough. Rename the local rpmatch() implementation to avoid collision.

With the addition of block device access to UBI volumes, we now add a simple userspace tool to access the new ioctls. Usage of this tool is as simple as it gets: $ ubiblock --create /dev/ubi0_0 will create a new block device /dev/ubiblock0_0, and $ ubiblock --remove /dev/ubi0_0 will remove the device.

2013-07-01move _GNU_SOURCE to the main makefileMike Frysinger
A bunch of utils are relying on _GNU_SOURCE already. The new prompt code uses getline() which is now part of POSIX, but in older versions of glibc, it was behind _GNU_SOURCE as it was a GNU extension. This change doesn't actually tie us to glibc. Only code that uses GNU extensions does that. It just kills warning when using older versions of glibc.

2011-06-08libmtd: improve mtd_islocked interfaceArtem Bityutskiy
This patch first of all, re-names 'mtd_islocked()' into 'mtd_is_locked()' since this seems to be the name Mike wanted, and it looks a bit nicer. This patch also makes 'mtd_is_locked()' print an error message if it fails. I'm not sure if it is good idea for a library to do so, but all functions do this, so it certainly _not_ a good idea to be inconsistent. However, for the special case, when the the "is locked" ioctl is not supported or is not valid for this device, we do not print an error message and return ENOTSUPP error code. Thus, the user can distinguish between real errors and non-fatal "not supported" cases. Signed-off-by: Artem Bityutskiy <Artem.Bityutskiy@nokia.com>

2011-02-25mtd-utils: common.h: simple_strtoll type usageBrian Norris
We must use "long long" and "unsigned long long" types when implementing the functions "simple_strtoll()" and "simple_strtoull()", respectively. This prevents casting/truncation errors on systems where "long" is not the same size as "long long" (that is, on most systems).

2010-10-01mtd-utils: xalloc: simplify/unify error messagesMike Frysinger
I'm not sure that if we actually are out of memory that declaring the failing allocation size is useful in the output. So use the same simple string in every error message to cut down on size (there will only be one copy of this at runtime). Size is a much more common concern than handling OOM issues which most likely aren't the fault of mtd-utils in the first place.

2010-07-26libmtd: add OOB read and write interfacesArtem Bityutskiy
This patch is based on Kevin Cernekee's patch posted to the MTD mailing list. It adds 'mtd_read_oob()' and 'mtd_write_oob()' interfaces support. The interfaces use MEMREADOOB64/MEMWRITEOOB64 MTD ioctls if possible, and fall-back to MEMREADOOB/MEMWRITEOOB if the 64-bit versions are not supported. The information about ioctls support is then cashed in 'offs64_ioctls' libmtd flag. Signed-off-by: Artem Bityutskiy <Artem.Bityutskiy@nokia.com>
2010-07-26libmtd: support MEMERASE64Artem Bityutskiy
This patch is base on Kevin Cernekee's patch posted to the MTD mailing list. It adds MEMERASE64 support to the 'mtd_erase()' call. Now it first tries to use MEMERASE64, and if that is not supported, falls back to the old MEMERASE ioctl. This patch also introduces an 'offs64_ioctl' flag to the libmtd descriptor. However, we cannot initialize it in 'libmtd_open()', because we need an MTD device node, which we do not have in 'libmtd_open()'. Thus, we firs mark this flag as "uninitialized", and at the first invocation of 'mtd_erase()' we initialize it. This also means that we have to pass the limbtd descriptor to 'mtd_erase()', to save the flag value. This, in turn, requires tweaking 'mtd_erase()' users. This is not very nice, but good enough so far. Signed-off-by: Artem Bityutskiy <Artem.Bityutskiy@nokia.com>
