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. Signed-off-by: David Oberhollenzer <> Signed-off-by: Richard Weinberger <>

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. Signed-off-by: David Oberhollenzer <> Signed-off-by: Richard Weinberger <>

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 - 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 <> Signed-off-by: Richard Weinberger <>
2016-11-17Remove feature-removal-schedule.txtDavid Oberhollenzer
This patch removes the old feature-removal-schedule.txt file from mtd-utils, mostly for reasons similar to the ones that lead to the decision of removing the feature-removal-schedule.txt from the kernel. Removing features by itself is rather problematic as there is no simple way of estimating whether something is being used widley or not at all. Thus, consensus usually tends towards not removing features at all. Even if there is a file anouncing feature removal, users in large won't read this file _if_ it is even included in distribution packages. People working on mtd-uils would end up removing features that _they_ find useless and users would start complaining once their setups break after they install a new version of mtd-utils. In conclusion, once introduced, features should not be removed to begin with and this file is entirely usless. Signed-off-by: David Oberhollenzer <>
2016-11-17Remove duplicate copies of GPLv2 license textDavid Oberhollenzer
Some of the programs in the mtd-utils used to be seperate packages that were at some point merged into mtd-utils. As a result, some subdirectories contain their own README and COPYING files with copies of the GPLv2 license text. Since those programs are now part of mtd-utils that contains a copy of the GPLv2 in the file COPYING in the package root directory, those extra files can be removed, as there is no need for distributing an extra copy of the license text for each individual program in the bundle.

2016-11-17Remove RPM spec fileDavid Oberhollenzer
Building packages for distributions is typically something highly distribution specific. While there are widely used package formats like RPM, implementing a de-facto standard, the build process, list of files actually packaged, list of required dependencies, package grouping, package versioning, etc... is still _very_ distribution specific. In fact, this spec file completely fails to address some of these points. Actual RPM based distributions out there currently use their own, distribution specific, RPM spec files that were possibly _based_ on this one at some point (judging from similar descriptions). The spec file _may_ have worked at some point, but it definitely doesn't work with the new build system and there is no real reason to fix it (which, by definition, isn't possible for the reasons above) and drag it along for another decade or two.

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".

2016-11-17Remove jffs-dump.cDavid Oberhollenzer
This _entire_ file is dead code. The download packages on the FTP server contain it all the way back to mtd-utils 1.0, but it isn't built in any of them. The git history (which dates back to 2006) contains no instance where that file was ever used in a build process. A quick look at various distribution packages didn't reveal any that contained a jffs-dump utilty. There have been no major changes to this file since the initial commit. It won't even compile as it doesn't have a PROGRAM_NAME defined required by common.h at least since 2010. At this point, it can be safeley assumed that nobody will miss this. They had at least 10 years to do something about it. Signed-off-by: David Oberhollenzer <> Signed-off-by: Richard Weinberger <>
2016-11-17Eliminate warnings about implicit non-const casting in libmtdDavid Oberhollenzer
The mtd_get_dev_info1 function reads (among other things) name and type string into coresponding struct mtd_dev_info fields. The struct mtd_dev_info has the string fields marked const, requiring them to be cast to non-const version during initialization. This cast was previously omitted from the dev_read_data calls, triggering warnings during compilation. Signed-off-by: David Oberhollenzer <> Signed-off-by: Richard Weinberger <>
2016-11-17nanddump: check write function result for errorsRafał Miłecki
Errors may happen, it's e.g. easy on embedded devices to run out of space when dumping big partitions. This patch adds a helper function for writing. It deals with partial writes and just returns 0 on success or error number. The old code didn't check for errors at all which could result in incomplete dumps without exiting with an error.

2016-08-25mtd-utils: mkfs.jffs2: initialize lzo decompression buffer sizeDavid Oberhollenzer
This fix was initialially part of a patch submitted by Carsten Schlote in January 2009. It didn't get merged back then because of coding style issues and a proposed buffer size change guessed by shotgun debugging. I was unable to reproduce the claimed segfaults in the compression function that lead to the proposed buffer size change. Valgrind did not issue any errors or warnings about the code in question either, so I didn't include the proposed buffer size change. The original patch also added a call to lzo_init(), which (according to LZO documentation & source code) does not actually perform any initialization, but only checks at runtime that the data type sizes and endianness of the library code match those in the caller code and should be unnecessary. Other fixes from the original patch have already been added over the years. Signed-off-by: David Oberhollenzer <> Signed-off-by: Richard Weinberger <>

2016-08-25mtd-utils: mtd_debug: check amount of data read.Michal Suchanek
The kernel refuses to read more data from a MTD device than the device size. However, mtd_debug does not check the amount of data read as returned by read(2) and assumes the requested amount is always read when there is no error. Reading 8M data from a 4M flash chip results in 8M file containing the flash data at the start. Signed-off-by: Michal Suchanek <> Signed-off-by: Richard Weinberger <>

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.

2015-11-12mkfs.ubifs: Optionally create extended attribute with inode numberSascha Hauer
This is done to allow creating images suitable for IMA directory appraisal. IMA creates a hash for directories and attaches this hash to the directory itself as an extended attribute. Among other things the inode numbers of the files are hashed. So, to create a valid hash in the UBIFS image the evmctl tool needs to know the inode numbers which the files in the UBIFS image will have. evmctl will read the inode numbers from the user.image-inode-number extended attribute. Since extended attributes are inodes themselves the inode numbers for the generated image will change when the extended attributes change, so to generate a correctly hashed UBIFS image, both evmctl and mkfs.ubifs must be run twice: 1) execute evmctl to iterate over the directory tree. This will create the security.ima and security.evm extended attributes. The existence of the attributes makes sure that subsequent calls to mkfs.ubifs will use the same inode numbers. evmctl will use the inode numbers from the host filesystem in this step which makes the resulting image unusable 2) execute mkfs.ubifs -a. This will create the user.image-inode-number extended attributes on files/directories added to the image. 3) execture evmctl again. This time evmctl will pick the inode numbers from the user.image-inode-number extended attribute instead of the ones from the host filesystem 4) execute mkfs.ubifs again. This will create the correct image. The now existing user.image-inode-number extended attributes are ignored and not added to the image.
