Masahiro Yamada 05e96e96a3 kbuild: use git-archive for source package creation
Commit 5c3d1d0abb ("kbuild: add a tool to list files ignored by git")
added a new tool, scripts/list-gitignored. My intention was to create
source packages without cleaning the source tree, without relying on git.

Linus strongly objected to it, and suggested using 'git archive' instead.
[1] [2] [3]

This commit goes in that direction - Remove scripts/list-gitignored.c
and rewrites Makefiles and scripts to use 'git archive' for building
Debian and RPM source packages. It also makes 'make perf-tar*-src-pkg'
use 'git archive' again.

Going forward, building source packages is only possible in a git-managed
tree. Building binary packages does not require git.

Masahiro Yamada 5c3d1d0abb kbuild: add a tool to list files ignored by git
In short, the motivation of this commit is to build a source package
without cleaning the source tree.

The deb-pkg and (src)rpm-pkg targets first run 'make clean' before
creating a source tarball. Otherwise build artifacts such as *.o,
*.a, etc. would be included in the tarball. Yet, the tarball ends up
containing several garbage files since 'make clean' does not clean
everything.

Cleaning the tree every time is annoying since it makes the incremental
build impossible. It is desirable to create a source tarball without
cleaning the tree.

In fact, there are some ways to achieve this.

The easiest solution is 'git archive'. 'make perf-tar*-src-pkg' uses
it, but I do not like it because it works only when the source tree is
managed by git, and all files you want in the tarball must be committed
in advance.

I want to make it work without relying on git. We can do this.

Files that are ignored by git are generated files, so should be excluded
from the source tarball. We can list them out by parsing the .gitignore
files. Of course, .gitignore does not cover all the cases, but it works
well enough.

tar(1) claims to support it:

  --exclude-vcs-ignores

    Exclude files that match patterns read from VCS-specific ignore files.
    Supported files are: .cvsignore, .gitignore, .bzrignore, and .hgignore.

The best scenario would be to use 'tar --exclude-vcs-ignores', but this
option does not work. --exclude-vcs-ignore does not understand any of
the negation (!), preceding slash, following slash, etc.. So, this option
is just useless.

Hence, I wrote this gitignore parser. The previous version [1], written
in Python, was so slow. This version is implemented in C, so it works
much faster.

I imported the code from git (commit: 23c56f7bd5f1), so we get the same
result.

This tool traverses the source tree, parsing all .gitignore files, and
prints file paths that are ignored by git.

The output is similar to 'git ls-files --ignored --directory --others
--exclude-per-directory=.gitignore', except

  [1] Not sorted
  [2] No trailing slash for directories

[2] is intentional because tar's --exclude-from option cannot handle
trailing slashes.

[How to test this tool]

The source tarball contains most of files that are tracked by git. You
see some diffs, but it is just because some .gitignore files are wrong.

Masahiro Yamada 596b0474d3 kbuild: preprocess module linker script
There was a request to preprocess the module linker script like we
do for the vmlinux one. (https://lkml.org/lkml/2020/8/21/512)

The difference between vmlinux.lds and module.lds is that the latter
is needed for external module builds, thus must be cleaned up by
'make mrproper' instead of 'make clean'. Also, it must be created
by 'make modules_prepare'.

You cannot put it in arch/$(SRCARCH)/kernel/, which is cleaned up by
'make clean'. I moved arch/$(SRCARCH)/kernel/module.lds to
arch/$(SRCARCH)/include/asm/module.lds.h, which is included from
scripts/module.lds.S.

scripts/module.lds is fine because 'make clean' keeps all the
build artifacts under scripts/.

You can add arch-specific sections in <asm/module.lds.h>.

Vivek Goyal 8370edea81 bin2c: move bin2c in scripts/basic
This patch series does not do kernel signature verification yet.  I plan
to post another patch series for that.  Now distributions are already
signing PE/COFF bzImage with PKCS7 signature I plan to parse and verify
those signatures.

Primary goal of this patchset is to prepare groundwork so that kernel
image can be signed and signatures be verified during kexec load.  This
should help with two things.

- It should allow kexec/kdump on secureboot enabled machines.

- In general it can help even without secureboot. By being able to verify
  kernel image signature in kexec, it should help with avoiding module
  signing restrictions. Matthew Garret showed how to boot into a custom
  kernel, modify first kernel's memory and then jump back to old kernel and
  bypass any policy one wants to.

This patch (of 15):

Kexec wants to use bin2c and it wants to use it really early in the build
process. See arch/x86/purgatory/ code in later patches.

So move bin2c in scripts/basic so that it can be built very early and
be usable by arch/x86/purgatory/

David Howells 4520c6a49a X.509: Add simple ASN.1 grammar compiler
Add a simple ASN.1 grammar compiler.  This produces a bytecode output that can
be fed to a decoder to inform the decoder how to interpret the ASN.1 stream it
is trying to parse.

Action functions can be specified in the grammar by interpolating:

	({ foo })

after a type, for example:

	SubjectPublicKeyInfo ::= SEQUENCE {
		algorithm		AlgorithmIdentifier,
		subjectPublicKey	BIT STRING ({ do_key_data })
		}

The decoder is expected to call these after matching this type and parsing the
contents if it is a constructed type.

The grammar compiler does not currently support the SET type (though it does
support SET OF) as I can't see a good way of tracking which members have been
encountered yet without using up extra stack space.

Currently, the grammar compiler will fail if more than 256 bytes of bytecode
would be produced or more than 256 actions have been specified as it uses
8-bit jump values and action indices to keep space usage down.

Dick Streefland 7b76bfc867 kconfig: simplification of scripts/extract-ikconfig
I've rewritten the extract-ikconfig script to extract the kernel
configuration from a kernel compiled with CONFIG_IKCONFIG. The main
motivation for the rewrite was to remove the dependency on the
external C program binoffset.c, which is compiled on the initial run.

The binoffset executable is invoked with a relative path, which means
that the old script can only be run from the top of the kernel tree,
and only when you have write permission in the scripts directory.

The new script uses tr/grep/tail/zcat only, and can be invoked from
anywhere. The binoffset.c program has been removed. This script
requires GNU grep 2.5 (released 2002-03-13) or higher, because the -o
option was introduced in that version.

David Woodhouse 556b0f58bb Revert "fix modules_install via NFS"
This reverts commit 8b249b6856.

This 'fix' is not necessary; we just need to undo the damage caused
accidentally by Igor/Mauro in 4b29631db3
("V4L/DVB (9533): cx88: Add support for TurboSight TBS8910 DVB-S PCI card")

Sam Ravnborg 8b249b6856 fix modules_install via NFS
Rafael reported:

I get the following error from 'make modules_install' on my test boxes:

  HOSTCC  firmware/ihex2fw
/home/rafael/src/linux-2.6/firmware/ihex2fw.c:268: fatal error: opening dependency file firmware/.ihex2fw.d: Read-only file system
compilation terminated.
make[3]: *** [firmware/ihex2fw] Error 1
make[2]: *** [_modinst_post] Error 2
make[1]: *** [sub-make] Error 2
make: *** [all] Error 2

where the configuration is that the kernel is compiled on a build box
with 'make O=<destdir> -j5' and then <destdir> is mounted over NFS read-only by
each test box (full path to this directory is the same on the build box and on
the test boxes).  Then, I cd into <destdir>, run 'make modules_install' and get
the error above.

The issue turns out to be that we when we install firmware pick
up the list of firmware blobs from firmware/Makefile.
And this triggers the Makefile rules to update ihex2fw.

There were two solutions for this issue:
1) Move the list of firmware blobs to a separate file
2) Avoid ihex2fw rebuild by moving it to scripts

As I seriously beleive that the list of firmware blobs should be
done in a fundamental different way solution 2) was selected.

Linus Torvalds 1e65174a33 Add some basic .gitignore files
This still leaves driver and architecture-specific subdirectories alone,
but gets rid of the bulk of the "generic" generated files that we should
ignore.
