2019-06-01	mkfs.ubifs: Add ZSTD compression	Sebastian Andrzej Siewior
	I added ZSTD support to mkfs.ubifs and compared the ZSTD results with zlib/lzo and the available ZSTD compression levels. The results are in the following table: Comp image MiB time image2 MiB time none 271 0m 0,723s 223 0m 0,589s lzo 164 0m13,705s 116 0m11,636s zlib 150 0m 7,654s 103 0m 6,347s favor-lzo 158 0m21,137s 110 0m17,764s zstd-01 154 0m 1,607s 106 0m 1,429s zstd-02 153 0m 1,704s 105 0m 1,479s zstd-03* 152 0m 1,888s 104 0m 1,668s zstd-04 151 0m 2,741s 103 0m 2,391s zstd-05 150 0m 3,257s 102 0m 2,916s zstd-06 150 0m 3,735s 102 0m 3,356s zstd-07 150 0m 4,066s 102 0m 3,705s zstd-08 152 0m 1,857s 104 0m 1,644s zstd-09 152 0m 1,855s 104 0m 1,639s zstd-10 150 0m 6,654s 102 0m 6,195s zstd-11 150 0m10,027s 102 0m 9,130s zstd-12 149 0m14,724s 101 0m13,415s zstd-13 148 0m18,232s 100 0m16,719s zstd-14 148 0m20,859s 100 0m19,554s zstd-15 148 0m25,033s 100 0m23,186s zstd-16 148 0m38,837s 100 0m36,543s zstd-17 148 0m46,051s 100 0m43,120s zstd-18 148 0m49,157s 100 0m45,807s zstd-19 148 0m49,421s 100 0m45,951s zstd-20 148 0m51,271s 100 0m48,030s zstd-21 148 0m51,015s 100 0m48,676s zstd-22 148 0m52,575s 100 0m50,013s The UBIFS image was created via mkfs.ubifs -x $Comp -m 512 -e 128KiB -c 2200 -r $image $out I used "debootstrap sid" to create a basic RFS and the results are in the `image' column. The image2 column denotes the results for the same image but with .deb files removed. The time column contains the output of the run time of the command. ZSTD's compression level three is currently default. Based on the compression results (for the default level) it outperforms LZO in run time and compression and is almost as good as ZLIB in terms of compression but quicker. The higher compression levels make almost no difference in compression but take a lot of time. The compression level used is the default offered by ZSTD. It does not make sense the higher levels.

2018-06-14	mkfs.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).

2016-11-17	Change build system to autotools	Richard 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>
