2018-11-01mkfs.ubifs: Use correct sizes for keys and hash lengthsRichard Weinberger
This works currently by chance since the sizes match, but that might change with different cipher setups. Signed-off-by: Richard Weinberger <richard@nod.at> Signed-off-by: David Oberhollenzer <david.oberhollenzer@sigma-star.at>

2018-11-01mkfs.ubifs: Make r5 hash binary string awareRichard Weinberger
As of now all filenames known by UBIFS are strings with a NUL terminator. With encrypted filenames a filename can be any binary string and the r5 function cannot search for the NUL terminator. UBIFS always knows how long a filename is, therefore we can change the hash function to iterate over the filename length to work correctly with binary strings.

2018-10-02mkfs.ubifs: Fix xattr nlink valueSascha Hauer
The nlink value of a xattr node must always be one, it has nothing to do with the nlink value of the inode the attribute belongs to. The bug can be observed when mounting a mkfs.ubifs generated image which contains xattrs on directories or files with hardlinks to them. When mounting such an image with chk_fs = 1 it fails with: UBIFS error (ubi0:0 pid 1833): dbg_check_filesystem: inode 3308 nlink is 3, but calculated nlink is 1 Another bug that can be triggered is an assertion in ubifs_xattr_remove() which assures that the xattr i_nlink count should be one when the xattr is removed.

2018-06-14mkfs.ubifs: Implement selinux labelling support in mkfs.ubifs.Ritesh Harjani
This implements/adds selinux labelling support to mkfs.ubifs utility. It adds an extra option in configure to enable selinux labelling support and then finally in mkfs.ubifs adds an extra option to pass the file_contexts which is looked up for filesystem file labels. - Default behavior is kept without selinux so as to not break existing support where selinux library/headers may not be present. - If this is configured with --with-selinux then XATTR from the file_contexts(passed with --selinux option while mkfs.ubifs) will be taken and not from the host file's xattr. This is done to avoid the problem where the host OS may have selinux enabled and hence same xattr names will be present in both host filesystem files and from the --selinux=file passed. So the existing behavior is kept mutually exclusive and preference is given to selinux xattrs (if configured with --with-selinux).

2018-06-14mkfs.ubifs: add_xattr is not depending on host XATTR supportRitesh Harjani
add_xattr adds the xattr to the ubifs image and has nothing to do with host XATTR support. Now that we are adding support where selinux interfaces may use this API even when host OS(where ubi/ubifs image is being created) does not support XATTR -so remove it from WITHOUT_XATTR #ifdef.

2018-03-07mkfs.ubifs: Allow root entry in device tableDavid Engraf
When using a local root folder the permissions, user and group settings are taken from the local folder. These permissions might be incorrect if the folder has been created for the local user. Creating an UBIFS image on my local system resulted in the following output on the target: drwx------ 17 1000 1000 1264 Jan 1 00:00 . drwx------ 17 1000 1000 1264 Jan 1 00:00 .. drwxr-xr-x 2 root root 9104 May 30 2017 bin drwxr-xr-x 7 root root 2760 Jan 1 00:00 dev ... mkfs.ubifs aborts with an error message when the device table contains a root entry. This patch allows setting the root folder permissions, user and group to overwrite local configurations.

2017-07-10mkfs-ubifs: fix inclusion of uuid.hRolf Eike Beer
The include directory exported by uuid.pc is */include/uuid, so uuid.h must be included without any directory in the path. This usually works out because uuid is installed in the normal prefix, so the parent directory of what uuid has as include dir ends up in the include path anyway. In case one uses a custom uuid outside of the regular include path this breaks. Signed-off-by: Rolf Eike Beer <eb@emlix.com> Signed-off-by: David Oberhollenzer <david.oberhollenzer@sigma-star.at>
2017-06-28Replace defunct ubifs_assertDavid Oberhollenzer

2017-06-14ubi-utils: Return error code if command line option is unknownDaniel Wagner
The tools in question will quit with an exit code 0 if the command line option was not recognized.

2016-11-17Change build system to autotoolsRichard Weinberger
This patch is largely based on Richards original RFC.

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.
