kbuild: fix spurious initramfs rebuild

2009-04-11T06:18:12+00:00

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.

bzip2/lzma: don't leave empty files around on failure

2009-02-19T21:39:21+00:00

Impact: Bugfix, silent build failures

Fix a bug in gen_initramfs_list.sh: in case of failure, it left an
empty output file behind, messing up the next make.

bzip2/lzma: fix built-in initramfs vs CONFIG_RD_GZIP

2009-01-07T08:10:27+00:00

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.

kbuild: fix unportability in gen_initramfs_list.sh

2008-04-28T20:50:51+00:00

On a Mac OS X machine the output of ls -l is different from a standard
Linux machine. Use readlink instead of parsing a hardcoded field number
from the ls output.

kbuild: add support for squashing uid/gid in gen_initramfs_list.sh

2007-07-16T19:15:52+00:00

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.

kbuild: propagate errors from find in scripts/gen_initramfs_list.sh

2007-05-02T18:58:11+00:00

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.  Stop.
make: *** [_all] Error 2

kbuild: handle compressed cpio initramfs-es

2007-05-02T18:58:10+00:00

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.

[PATCH] initramfs: handle more than one source dir or file list

2006-11-25T21:28:33+00:00

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.
