2017-01-12nandwrite: fix/cleanup bad block skippingDavid Oberhollenzer
JFFS2 supports clustering erase blocks to virtual erase blocks. nandwrite supports this, but previously mixed up virtual and physical erase block numbers when checking for bad blocks. This patch adds a function for checking if a virtual erase block is bad and replaces the broken mtd_is_bad loop. Signed-off-by: David Oberhollenzer <david.oberhollenzer@sigma-star.at>

2017-01-12nandwrite: add stricter sanity checking for blockalignDavid Oberhollenzer
This patch makes sure that a virtual erase block is always composed of a postivie number of erase blocks (i.e. 1 or more) and enforces the block alignment to be a power of two as suggested by the help text and assumed throughout the program.

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.

2016-12-06common: Fix 'unchecked return code' warningsBoris Brezillon

2016-12-06common: Fix PRI{x,d}off definitions for x86_64 platformBoris Brezillon
Compiling for x86_64 generates a lot of warning because the PRIxoff_t and PRIdoff_t are not properly defined, which comes from the missing SIZEOF_LONG definition. Use the autotools to generate a config.h header, include this header from common.h and ask autoheader to generate the SIZEOF_LONG and SIZEOF_LOFF_T definitions. Use these new definitions to assign the proper descriptors to PRIxoff_t and PRIdoff_t. Signed-off-by: Boris Brezillon <boris.brezillon@free-electrons.com>

2016-11-29Define WITHOUT_XATTR if sys/acl.h or sys/xattr.h is missingDavid Oberhollenzer
The programs mkfs.jffs2 and mkfs.ubifs include those two headers if WITHOUT_XATTR is not defined. Up to now, this macro is only defined if the configure script is run with --without-xattr. If the headers are not present on a system and the configure script is run without special flags set, the build fails. This patch adds a check for the presence of those headers and disables the feature if one of the headers is missing. Signed-off-by: David Oberhollenzer <david.oberhollenzer@sigma-star.at>

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>
2016-11-17Merge rest of ubiutils-common into libmtd commonDavid Oberhollenzer
This patch moves the remaining 3 functions from ubiutils-common.{c,h} into libmtd common.{c,h}. The functions are only generic utility functions that other mtd-utils programs may also find usefull and every program that uses libubi links against libmtd anyway so there is no real reason for keeping around a seperate ubiutils-common with only generic helper 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.

2016-11-17Remove 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 <david.oberhollenzer@sigma-star.at>
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 <david.oberhollenzer@sigma-star.at> Signed-off-by: Richard Weinberger <richard@nod.at>
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.

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.
