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

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

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

decompressors: add boot-time XZ support

2011-01-13T16:03:25Z

This implements the API defined in which is used for kernel, initramfs, and initrd decompression. This patch together with the first patch is enough for XZ-compressed initramfs and initrd; XZ-compressed kernel will need arch-specific changes. The buffering requirements described in decompress_unxz.c are stricter than with gzip, so the relevant changes should be done to the arch-specific code when adding support for XZ-compressed kernel. Similarly, the heap size in arch-specific pre-boot code may need to be increased (30 KiB is enough). The XZ decompressor needs memmove(), memeq() (memcmp() == 0), and memzero() (memset(ptr, 0, size)), which aren't available in all arch-specific pre-boot environments. I'm including simple versions in decompress_unxz.c, but a cleaner solution would naturally be nicer. Signed-off-by: Lasse Collin Cc: "H.
