2011-01-11UBIFS: Fix dereferencing type-punned pointer compiler warningDirk Behme
Fix compiler warning In file included from ubifs.h:2137:0, from ubifs.c:26: misc.h: In function 'ubifs_idx_key': misc.h:263:26: warning: dereferencing type-punned pointer will break strict-aliasing rules seen with gcc version 4.5.1 (Sourcery G++ Lite 2010.09-50). No functional change. CC: Stefan Roese <sr@denx.de> Signed-off-by: Dirk Behme <dirk.behme@googlemail.com> Signed-off-by: Stefan Roese <sr@denx.de>
2010-12-03ubifs.c: BUG: Error following linksRicardo Ribalda Delgado
The link_name variable is declared inside the if block and it is used outside it through the name pointer. Signed-off-by: Ricardo Ribalda Delgado <ricardo.ribalda@gmail.com> Signed-off-by: Stefan Roese <sr@denx.de>
2010-12-03UBIFS: Change ubifsload to not read beyond the requested sizeStefan Roese
Until now ubifsload pads the destination with 0 up to a multiple of UBIFS_BLOCK_SIZE (4KiB) while reading a file to memory. This patch changes this behaviour to only read to the requested length. This is either the file length or the length/size provided as parameter to the ubifsload command. Signed-off-by: Stefan Roese <sr@denx.de>
2010-12-03UBIFS: Add ubifsumount command to unmount an active volumeStefan Roese
This new ubifsumount command allows the user to unmount a previously mounted UBIFS volume. Signed-off-by: Stefan Roese <sr@denx.de>
2010-11-17Switch from archive libraries to partial linkingSebastien Carlier
Before this commit, weak symbols were not overridden by non-weak symbols found in archive libraries when linking with recent versions of binutils. As stated in the System V ABI, "the link editor does not extract archive members to resolve undefined weak symbols". This commit changes all Makefiles to use partial linking (ld -r) instead of creating library archives, which forces all symbols to participate in linking, allowing non-weak symbols to override weak symbols as intended. This approach is also used by Linux, from which the gmake function cmd_link_o_target (defined in config.mk and used in all Makefiles) is inspired. The name of each former library archive is preserved except for extensions which change from ".a" to ".o". This commit updates references accordingly where needed, in particular in some linker scripts. This commit reveals board configurations that exclude some features but include source files that depend these disabled features in the build, resulting in undefined symbols. Known such cases include: - disabling CMD_NET but not CMD_NFS; - enabling CONFIG_OF_LIBFDT but not CONFIG_QE. Signed-off-by: Sebastien Carlier <sebastien.carlier@gmail.com>
2010-10-29Replace CONFIG_RELOC_FIXUP_WORKS by CONFIG_NEEDS_MANUAL_RELOCWolfgang Denk
By now, the majority of architectures have working relocation support, so the few remaining architectures have become exceptions. To make this more obvious, we make working relocation now the default case, and flag the remaining cases with CONFIG_NEEDS_MANUAL_RELOC.

2010-04-28ubifsmount fails due to not initialized listStefano Babic
ubifsmount is not working and causes an access with a pointer set to zero because the ubifs_fs_type is not initialized correctly. Signed-off-by: Stefano Babic <sbabic@denx.de> Signed-off-by: Stefan Roese <sr@denx.de>
2009-12-21move prototypes for gunzip() and zunzip() to common.hWolfgang Wegner
Prototype for gunzip/zunzip was only in lib_generic/gunzip.c and thus repeated in every file using it. This patch moves the prototypes to common.h and removes all prototypes distributed anywhere else. Signed-off-by: Wolfgang Wegner <w.wegner@astro-kom.de>
2009-12-08common: delete CONFIG_SYS_64BIT_VSPRINTF and CONFIG_SYS_64BIT_STRTOULHeiko Schocher
There is more and more usage of printing 64bit values, so enable this feature generally, and delete the CONFIG_SYS_64BIT_VSPRINTF and CONFIG_SYS_64BIT_STRTOUL defines. Signed-off-by: Heiko Schocher <hs@denx.de>
2009-10-03Conditionally perform common relocation fixupsPeter Tyser
Add #ifdefs where necessary to not perform relocation fixups. This allows boards/architectures which support relocation to trim a decent chunk of code. Note that this patch doesn't add #ifdefs to architecture-specific code which does not support relocation. Signed-off-by: Peter Tyser <ptyser@xes-inc.com>
2009-09-28ubifs: Correct dereferencing of files-after-symlinksSimon Kagstrom
Files in directories which are symlinked to were not dereferenced correctly in last commit. E.g., with a symlink /boot/lnk -> /boot/real_dir loading /boot/lnk/uImage will fail. This patch fixes that by simply seeing to it that the target base directory has a slash after it.

2009-09-23ubifs: Add support for looking up directory and relative symlinksSimon Kagstrom
This patch adds support for resolving symlinks to directories as well as relative symlinks. Symlinks are now always resolved during file lookup, so the load stage no longer needs to special-case them.

2009-09-15Move __set/clear_bit from ubifs.h to bitops.hSimon Kagstrom
__set_bit and __clear_bit are defined in ubifs.h as well as in asm/include/bitops.h for some architectures. This patch moves the generic implementation to include/linux/bitops.h and uses that unless it's defined by the architecture. Signed-off-by: Simon Kagstrom <simon.kagstrom@netinsight.net>

2009-04-28ubifs: BUG realpath string must be ended with NULLRicardo Ribalda Delgado
If the memory used to copy the link_make is "dirty" the string wont be ended with NULL, throwing out multiple memory bugs. Signed-off-by: Ricardo Ribalda Delgado <ricardo.ribalda@uam.es> Acked-by: Stefan Roese <sr@denx.de>
2009-04-28UBIFS: Remove tnc_commit.c which is not used in the read-only versionStefan Roese
I missed removing this file while implementing the UBIFS support. It's not referenced at all, so let's remove it. Thanks to Artem Bityutskiy for spotting. Signed-off-by: Stefan Roese <sr@denx.de>
2009-04-28UBIFS: fix recovery bugAdrian Hunter
UBIFS did not recovery in a situation in which it could have. The relevant function assumed there could not be more nodes in an eraseblock after a corrupted node, but in fact the last (NAND) page written might contain anything. The correct approach is to check for empty space (0xFF bytes) from then on. Signed-off-by: Adrian Hunter <adrian.hunter@nokia.com> Signed-off-by: Stefan Roese <sr@denx.de>
2009-04-05Update CHANGELOG, coding style cleanup.Wolfgang Denk
2009-04-04UBIFS: add R/O compatibilityArtem Bityutskiy
Now UBIFS is supported by u-boot. If we ever decide to change the media format, then people will have to upgrade their u-boots to mount new format images. However, very often it is possible to preserve R/O forward-compatibility, even though the write forward-compatibility is not preserved. This patch introduces a new super-block field which stores the R/O compatibility version.

2009-03-20UBIFS: Missing offset relocation for compressor 'none'Michael Lawnick
On systems where U-Boot is linked to another address than it really lays (e.g. backup image), calls via function pointers must be fixed with a '+= gd->reloc_off'. This was not done for none_compr in ubifs_compressors_init() what leads to system crash on ubifsmount command. Signed-off-by: Michael Lawnick <ml.lawnick@gmx.de> Acked-by: Stefan Roese <sr@denx.de>
2009-03-20UBIFS: Implement read-only UBIFS support in U-BootStefan Roese
The U-Boot UBIFS implementation is largely a direct copy from the current Linux version (2.6.29-rc6). As already done in the UBI version we have an "abstraction layer" to redefine or remove some OS calls (e.g. mutex_lock() ...). This makes it possible to use the original Linux code with very little changes. And by this we can better update to later Linux versions. I removed some of the Linux features that are not used in the U-Boot version (e.g. garbage-collection, write support).
