kbuild: create deterministic initramfs directory listings

2017-07-02T23:02:09Z

kbuild runs "find" on each entry in CONFIG_INITRAMFS_SOURCE that is a directory. The order of the file listing output by "find" matter for build reproducability, hence this patch applies "sort" to get deterministic results. Without this patch, two different machines with identical initramfs directory input may produce differing initramfs cpio archives (different hash) due to the different order of the files within the archive.

initramfs: Escape colons in depfile

2016-09-23T08:35:32Z

Special characters are problematic in depfiles, but we can fix colons easily. Reported-by: Florian Fainelli Signed-off-by: Michal Marek

kbuild: Make scripts executable

2014-08-20T14:03:45Z

The Makefiles call the respective interpreter explicitly, but this makes it easier to use the scripts manually. Signed-off-by: Michal Marek

scripts/gen_initramfs_list.sh: fix flags for initramfs LZ4 compression

2014-03-04T15:55:48Z

LZ4 as implemented in the kernel differs from the default method now used by the reference implementation of LZ4. Until the in-kernel method is updated to support the new default, passing the legacy flag (-l) to the compressor is necessary. Without this flag the kernel-generated, LZ4-compressed initramfs is junk. Kyungsik said: : It seems that lz4 supports legacy format with the same option as lz4c : does. Just looking at the first few bytes of lz4 compressed image, we can : see whether it is new format or not. : : It shows new format magic number without this patch. New format magic : number is 0x184d2204. : : $ hexdump -C ./initramfs_data.cpio.lz4 |more : 00000000 04 22 4d 18 64 70 b9 69 (Little Endian) : ... : : Currently kernel supports legacy format only.

initramfs: read CONFIG_RD_ variables for initramfs compression

2013-11-13T03:09:26Z

When expert configuration option(CONFIG_EXPERT) is enabled, menuconfig offers a choice of compression algorithm to compress initial ramfs image; This choice is stored into CONFIG_RD_* variables. But usr/Makefile uses earlier INITRAMFS_COMPRESSION_* macros to build initial ramfs file. Since none of them is defined, resulting 'initramfs_data.cpio' file remains un-compressed. This patch updates the Makefile to use CONFIG_RD_* variables and adds support for LZ4 compression algorithm. Also updates the 'gen_initramfs_list.sh' script to check whether a selected compression command is accessible or not. And fall-back to default gzip(1) compression when it is not.

scripts/gen_initramfs_list.sh: Convert to a /bin/sh script

2011-05-12T14:48:39Z

Replace bashisms with POSIX-compatible shell scripting. Notably, de-duplicate '/' using a sed command from elsewhere in the same script rather than "${name//\/\///}".

initramfs: Use KBUILD_BUILD_TIMESTAMP for generated entries

2011-04-18T12:27:52Z

gen_init_cpio gets the current time and uses it for each symlink, special file, and directory. Grab the current time once and make it possible to override it with the KBUILD_BUILD_TIMESTAMP variable for reproducible builds. Signed-off-by: Michal Marek
