kbuild: add support for reading stdin with gen_init_cpio

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

Treat an argument of "-" as meaning "read stdin for cpio files" so
gen_init_cpio can be piped into.

.gitignore update

2007-07-16T16:05:52+00:00

headers_install by default puts headers into usr/include/ .
They're auto-generated, so should be ignored.

Same for *.orig, *.rej .

[PATCH] usr/gen_init_cpio.c: support for hard links

2007-02-11T18:51:25+00:00

Extend usr/gen_init_cpio.c "file" entry, adding support for hard links.

Previous format:
file     

New format:
file      []

The hard links specification is optional, keeping the previous
behaviour.

All hard links are defined sequentially in the resulting cpio and the
file data is present only in the last link. This is the behaviour of
GNU's cpio and is supported by the kernel initramfs extractor.

[PATCH] disable init/initramfs.c

2007-02-11T18:51:25+00:00

The file init/initramfs.c is always compiled and linked in the kernel
vmlinux even when BLK_DEV_RAM and BLK_DEV_INITRD are disabled and the
system isn't using any form of an initramfs or initrd.  In this situation
the code is only used to unpack a (static) default initial rootfilesystem.
The current init/initramfs.c code.  usr/initramfs_data.o compiles to a size
of ~15 kbytes.  Disabling BLK_DEV_RAM and BLK_DEV_INTRD shrinks the kernel
code size with ~60 Kbytes.

This patch avoids compiling in the code and data for initramfs support if
CONFIG_BLK_DEV_INITRD is not defined.  Instead of the initramfs code and
data it uses a small routine in init/noinitramfs.c to setup an initial
static default environment for mounting a rootfilesystem later on in the
kernel initialisation process.  The new code is: 164 bytes of size.

The patch is separated in two parts:
1) doesn't compile initramfs code when CONFIG_BLK_DEV_INITRD is not set
2) changing all plaforms vmlinux.lds.S files to not reserve an area of
PAGE_SIZE when CONFIG_BLK_DEV_INITRD is not set.

[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.

kbuild: consistently decide when to rebuild a target

2006-09-25T07:00:00+00:00

Consistently decide when to rebuild a target across all of
if_changed, if_changed_dep, if_changed_rule.
PHONY targets are now treated alike (ignored) for all targets

While add it make Kbuild.include almost readable by factoring out a few
bits to some common variables and reuse this in Makefile.build.

kbuild: do not try to build content of initramfs

2006-08-07T18:58:28+00:00

When a file supplied via CONFIG_INITRAMFS pointed to a file
for which kbuild had a rule to compile it (foo.c => foo.o)
then kbuild would compile the file before adding the
file to the initramfs.

Teach make that files included in initramfs shall not be updated by adding
an 'empty command'. (See "Using Empty Commands" in info make).

[PATCH] Fix potential NULL pointer deref in gen_init_cpio

2006-04-19T16:13:52+00:00

Fix potential NULL pointer deref in gen_init_cpio.c spotted by coverity
checker.  This fixes coverity bug #86

Without this patch we risk dereferencing a NULL `type' in the
"if ('\n' == *type) {" line.
