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.

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.

This implements the API defined in <linux/decompress/generic.h> 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: NLasse Collin <lasse.collin@tukaani.org> Cc: "H.

When gen_initramfs_list is used to generate make dependencies, it includes symbolic links, for which make tracks the link target. Any change to that target will cause an initramfs rebuild, even if the symlink points to something outside of the initramfs directory. If the target happens to be /tmp, the rebuild occurs for each kernel build, since gen_initramfs_list uses mktemp... Proposed way to fix it is to omit symbolic links from generated dependencies, but this has a small drawback: changing perm/owner on a symlink will go unnoticed.

Impact: Resolves build failures in some configurations Makes it possible to disable CONFIG_RD_GZIP . In that case, the built-in initramfs will be compressed by whatever compressor is available (bzip2 or lzma) or left uncompressed if none is available. It also removes a couple of warnings which occur when no ramdisk compression at all is chosen. It also restores the select ZLIB_INFLATE in drivers/block/Kconfig which somehow came missing. This is needed to activate compilation of the stuff in zlib_deflate. Signed-off-by: NAlain Knaff <alain@knaff.lu> Signed-off-by: NH. Peter Anvin <hpa@zytor.com>

Sometimes it is useful to squash all uid's/gid's to 0:0 regardless of current owner. For example, in build systems that get run as arbitrary users (uClinux-dist). This adds a special "squash" keyword so you can do '-g squash -u squash' and have ownership squashed to root.

If the find(1) in scripts/gen_initramfs_list.sh generates any errors, it will cause gen_initramfs_list.sh to fail (because of "set -e"), however the errors from find are not printed to the user. This is rather confusing: ~/src/powerpc$ make O=~/build/powerpc-cell32/ make[2]: *** [usr/initramfs_data.cpio.gz] Error 1 make[1]: *** [usr] Error 2 make[1]: *** Waiting for unfinished jobs.... make[1]: *** wait: No child processes. Stop. make: *** [_all] Error 2 It is much easier to work out what the problem is if we let the errors from find hit the console, eg: ~/src/powerpc$ make O=~/build/powerpc-cell32/ find: /home/michael/initramfs-source/home: Permission denied find: /home/michael/initramfs-source/lost+found: Permission denied find: /home/michael/initramfs-source/opt: Permission denied find: /home/michael/initramfs-source/root: Permission denied make[2]: *** [usr/initramfs_data.cpio.gz] Error 1 make[1]: *** [usr] Error 2 make[1]: *** Waiting for unfinished jobs.... make[1]: *** wait: No child processes.

Make kbuild handle compressed cpio initramfs-es. An already compressed cpio is copied directly to usr/, while a non-compressed cpio is filtered through gzip (no changes here) on its way to usr/. If the user has created a compressed cpio by other means, this saves him from uncompressing it, just to be compressed again by kbuild.

Fix bug 7401. Handle more than one source dir or file list to the initramfs gen scripts. The Kconfig help for INITRAMFS_SOURCE claims that you can specify multiple space-separated sources in order to allow unprivileged users to build an image. There are two bugs in the current implementation that prevent this from working. First, we pass "file1 dir2" to the gen_initramfs_list.sh script, which it obviously can't open. Second, gen_initramfs_list.sh -l outputs multiple definitions for deps_initramfs -- one for each argument.

initramfs.cpio.gz being build in usr/ and included in the kernel was not rebuild when the included files changed. To fix this the following was done: - let gen_initramfs.sh generate a list of files and directories included in the initramfs - gen_initramfs generate the gzipped cpio archive so we could simplify the kbuild file (Makefile) - utilising the kbuild infrastructure so when uid/gid root mapping changes the initramfs will be rebuild With this change we have a much more robust initramfs generation.

Initial git repository build. I'm not bothering with the full history, even though we have it. We can create a separate "historical" git archive of that later if we want to, and in the meantime it's about 3.2GB when imported into git - space that would just make the early git days unnecessarily complicated, when we don't have a lot of good infrastructure for it. Let it rip!
