The Linux buildsystem tries to run the compiler even just for
'kernelrelease' (which we store in LINUX_VERSION_PROBED) and we
sometimes need to use it before the toolchain is available; thus
we get spurious errors on stderr.
Consign stderr to oblivion when computing the 'kernelrelease'.

This commit add an infrastructure to build linux kernel

Currently, the only linux kernel tool packaged in Buildroot
is perf and it's packaged as a separate generic package.
This is a problem for licence information raised in this

Since these tools require to build a Linux kernel, we can
use some hooks in linux package like we did for linux
extensions [2] and remove the perf package.

The ktap package requires some parts of the kernel tracing
infrastructure to be enabled, especially
CONFIG_EVENT_TRACING. However, this option is a blind option in the
kernel, so enabling it in linux.mk has no effect: we need to enable a
non-blind option that selects CONFIG_EVENT_TRACING. We've chosen to
select CONFIG_ENABLE_DEFAULT_TRACERS.
This fixes the build of ktap.

This commit removes BR2_LINUX_KERNEL_EXT_RTAI_PATCH because this
option never worked. It was added in commit
8797a9cd1f, which added package/rtai/
and RTAI as a Linux extension.
The option prompt says "Path for RTAI patch file", so let's say you
specify /home/foo/bar/myrtai.patch as the value for
BR2_LINUX_KERNEL_EXT_RTAI_PATCH.
Then the code does:
RTAI_PATCH = $(call qstrip,$(BR2_LINUX_KERNEL_EXT_RTAI_PATCH))
and we have a package called 'rtai', so the normal logic of
<pkg>_PATCH applies. Since the <pkg>_PATCH value does not contain
ftp://, http:// or https://, the package infrastructure will try to
download $(RTAI_SITE)/$(RTAI_PATCH), i.e:
https://www.rtai.org/userfiles/downloads/RTAI/home/foo/bar/myrtai.patch
Pretty clear that it has no chance of working.
Now, let's assume an URL is used as the value of
BR2_LINUX_KERNEL_EXT_RTAI_PATCH, such as
http://foo.com/bar/myrtai.patch. In this case, it will be properly
downloaded by the package infrastructure. But then, the following code
kicks in:
define RTAI_PREPARE_KERNEL
$(APPLY_PATCHES) \
$(LINUX_DIR) \
$(dir $(RTAI_PATCH)) \
$(notdir $(RTAI_PATCH))
endef
The value of $(dir $(RTAI_PATCH)) will be http://foo.com/bar/. How
can $(APPLY_PATCHES) make use of such a stupid patch location?

if we believe that no-one could have ever used this option.]

Curently, all three linux extensions follow the same layout:
- test if the extension is enabled
- add itself to linux' patch-dependencies
- declare a macro, added as the pre-patch hook
Except for the macro, all can be commonalised.
Add a simple infrastructure for that:
- extensions declare themselves in the list of extensions
- extensions define their macro
- the infra adds them to the patch-dependencies and pre-patch
hooks as appropriate

Since the move to the kconfig-package infra, linux extensions are
broken.
In our linux package, extensions are applied as pre-patch hooks.
Before the kconfig-package infra, we had custom rules for the
linux-*config targets, which were of the form:
linux-menuconfig: linux-configure
$(MAKE) -C $(LINUX_DIR) menuconfig
This caused the linux tree to be fully configured before running the
configurators, and thus linux dependencies were entirely fullfilled, and
extensions were properly applied.
Since we migrated (in dff25ea), the kconfig-package infra introduces a
(hidden, internal) intermediate step 'kconfig-fixup' and decorelates the
kconfig-part of the configuration from the actual package-part of the
configuration:
linux-configure -------> kconfig-fixup --> .config --> $(LINUX_CONFIG_FILE)
/
linux-menuconfig --'
As thus, this (very useful!) use-case breaks (starting from a clean
Buildroot tree):
make menuconfig
-> enable a kernel and at least one extension
-> save and exit
make linux-menuconfig
-> extensions are not available
Fix that by using the newly-introduced patch-dependencies, so that
extensions are available before we try to patch the linux kernel.

before the BR2_GLOBAL_PATCH_DIR mechanism: at91bootstrap,

those packages to apply custom patches is to match
<package-name>-*.patch, which is not consistent with what we've done

The linux package has a special handling of patches, with quite a bit
of legacy in it. A problem caused by this special handling is that the
linux package calls directly the DOWNLOAD_WGET macro, which means that
the package infrastructure isn't aware of which patches get
downloaded, and it prevents doing changes inside the package download
infrastructure.
This commit changes the handling of patches in the linux package in
the following way:
* The LINUX_PATCHES variable is kept as is: it lists all the patches
mentioned in the Config.in option BR2_LINUX_KERNEL_PATCH. This
option can contain http://, ftp://, https:// URLs, path to local
files or local directories.
This variable is *not* used by the generic package infrastructure,
so it is purely internal to the Linux package.
* The LINUX_PATCH variable is now filled in with the list of patches
that should be downloaded. It is derived from LINUX_PATCHES by
filtering the patches that have http://, ftp:// or https:// in
their path. Since <pkg>_PATCH is handled by the package
infrastructure, it means that those patches are now automatically
downloaded and applied by the package infrastructure.
* The LINUX_APPLY_PATCHES hook is renamed to
LINUX_APPLY_LOCAL_PATCHES, because it is now only responsible of
applying local patches: remote patches are handled by
LINUX_PATCH. The implementation of the hook is changed to filter
out the patches that have already taken care of by LINUX_PATCH, so
that we only iterate through the list of local patches or local
patch directories.

When Buildroot is configured to append the root filesystem to the Linux
kernel as initramfs, Buildroot sets the path to the initramfs source
dynamically in the Linux configuration file.
As this path is specified as an absolute path, typically being different
for different users of the same project (e.g. containing a username),
saving the configuration to a version control system (for example using
'make linux-update-defconfig') would result in a difference for this
path at every invocation by a different user.
Although this is technically not an issue, it is confusing that this
generates a difference.
Address this issue by using a not-yet-expanded make variable to specify
the path to the initramfs source. That variable will be expanded by the
Linux build system, which uses it both as a Makefile variable and a
shell variable; thus, it needs to be specified in LINUX_MAKE_ENV (so
it is exported and available in sub-processes of make). Any saved
configuration file would simply contain the reference to the
not-yet-expanded variable.
As in the Linux build system, the config variables are both read from
make as from a shell script, we cannot use $() syntax as this would be
interpreted as a command invocation by the shell. Instead, use ${}
syntax which is interpreted as variable reference both by the shell as
by make.
[Thomas:
- Really make the patch work by using $(LINUX_MAKE_ENV) instead of
$(TARGET_MAKE_ENV). Otherwise, the new BR2_BINARIES_DIR variable is
not passed at all stages of the build process, which makes the
build fail when an initramfs is used.]

112 ifeq ($(LINUX_IMAGE_NAME),)
113 LINUX_IMAGE_NAME = $(LINUX_TARGET_NAME)

Even though they are defined in a way that ensures they are in fact not
recursively defined (the if-block ensures that), 'printvars' does dump
all our variables by evaluating all of them, which in that specific case
implies they are recursively defined.
Fix that by explicitly setting LINUX_IMAGE_NAME in each if-block.

The Buildroot coding style defines one space around make assignments and
does not align the assignment symbols.
This patch does a bulk fix of offending packages. The package
infrastructures (or more in general assignments to calculated variable
names, like $(2)_FOO) are not touched.
Alignment of line continuation characters (\) is kept as-is.
The sed command used to do this replacement is:
find * -name "*.mk" | xargs sed -i \
-e 's#^\([A-Z0-9a-z_]\+\)\s*\([?:+]\?=\)\s*$#\1 \2#'
-e 's#^\([A-Z0-9a-z_]\+\)\s*\([?:+]\?=\)\s*\([^\\]\+\)$#\1 \2 \3#'
-e 's#^\([A-Z0-9a-z_]\+\)\s*\([?:+]\?=\)\s*\([^\\ \t]\+\s*\\\)\s*$#\1 \2 \3#'
-e 's#^\([A-Z0-9a-z_]\+\)\s*\([?:+]\?=\)\(\s*\\\)#\1 \2\3#'
Brief explanation of this command:
^\([A-Z0-9a-z_]\+\) a regular variable at the beginning of the line
\([?:+]\?=\) any assignment character =, :=, ?=, +=
\([^\\]\+\) any string not containing a line continuation
\([^\\ \t]\+\s*\\\) string, optional whitespace, followed by a
line continuation character
\(\s*\\\) optional whitespace, followed by a line
continuation character
Hence, the first subexpression handles empty assignments, the second
handles regular assignments, the third handles regular assignments with
line continuation, and the fourth empty assignments with line
continuation.
This expression was tested on following test text: (initial tab not
included)
FOO = spaces before
FOO = spaces before and after
FOO = tab before
FOO = tab and spaces before
FOO = tab after
FOO = tab and spaces after
FOO = spaces and tab after
FOO = \
FOO = bar \
FOO = bar space \
FOO = \
GENIMAGE_DEPENDENCIES = host-pkgconf libconfuse
FOO += spaces before
FOO ?= spaces before and after
FOO :=
FOO =
FOO =
FOO =
FOO =
$(MAKE1) CROSS_COMPILE=$(TARGET_CROSS) -C
AT91BOOTSTRAP3_DEFCONFIG = \
AXEL_DISABLE_I18N=--i18n=0
After this bulk change, following manual fixups were done:
- fix line continuation alignment in cegui06 and spice (the sed
expression leaves the number of whitespace between the value and line
continuation character intact, but the whitespace before that could have
changed, causing misalignment.
- qt5base was reverted, as this package uses extensive alignment which
actually makes the code more readable.
Finally, the end result was manually reviewed.

The linux-* mirror targets of linux26-* have been added a very long time ago
(2010) and linux 2.6 is now considered 'old' anyway. It no longer makes
sense to support these linux26-* targets, so this patch removes them.

The echo statements in the kconfig helpers are currently using double
quotes. For KCONFIG_SET_OPT this is problematic when the value argument
itself contains a double quote (a string value). In this case, the statement
echo "$(1)=$(2)" >> $(3)
would become:
echo "FOO="string value"" >> /some/path/.config
resulting in the string
FOO=string value
in the config file, rather than the properly quoted
FOO="string value"
The linux package worked around this by escaping the quote characters, but
a prettier solution is to use single quoting in the helpers (or
alternatively use no quoting at all).
A side effect of this change is that a $variable in the key or value would
no longer be interpreted by the shell, removing any unexpected behavior.
This change is only really necessary for KCONFIG_SET_OPT, but for symmetry
reasons the other helpers are updated too.

SMACK stands for Simplified Mandatory Access Control Kernel. It is a Linux
Security Module which provides a Mandatory Access Control mechanism,
like SELinux, but aiming towards simplicity.
This package provides the tools to load/unload the policy from the
kernel as well as a library allowing applications to interact with
SMACK. The proper kernel options are also set.
[Thomas:
- fixed license to be LGPLv2.1 instead of LGPLv2.1+. Even though the
debian/copyright file has the "or later" indication, none of the .c
source files carry it, so I suppose LGPLv2.1 is more correct.

There is no reason to always depend on host-lzop, even when the kernel
compression is not LZO.
Since LZO is not the default compression option in the kernel (and there
is not sign that will change in the foreseeable future), it will always
appear in a config file, whether it is a complete config file or it is
only a defconfig.
So, only depend on host-lzop if the LZO compression is enabled in the
kernel config file (either the defconfig or the custom config file).
This includes:
- kernel compression itself
- initrd compression
- initramfs compression

This patch bumps systemd to v207 but also declares it as a provider for the
udev virtual package.
Starting with systemd 183, udev has been merged into
systemd. The udev daemon is now installed as /lib/systemd/systemd-udevd.
This means that /dev management using udev is only available if systemd
is chosen as init system.
When configuring systemd, the following options are available:
- activation of systemd-journal-gatewayd, to access the journal via
HTTP.
- activation of extra features like journal compression and sealing.
Support for uClibc has also been removed because:
- upstream has no interest in supporting uClibc.
- using a shrinked libc brings no advantage, given the size of all the
programs included in Systemd. So using glibc does not matter.

Features:
- No extra configuration options are available: Gudev is build if
libglib2 is selected.
- No dependency on hwdata as the package uses its own hardware
database (as does systemd).
eudev 1.3 is in sync with systemd v207.

When mdev /dev management is chosen in the buildroot configuration, the
Linux configuration is updated automatically to set option
CONFIG_UEVENT_HELPER_PATH to "/sbin/mdev". However, the help text of this
option explicitly recommends not setting this option due to large
performance impact during boot (experienced first hand by the reporter ánd
author).
The mdev startup script S10mdev already sets the helper during userspace
boot, which will make sure mdev is working correctly.

When one enables the generation of a cpio archive of the root
filesystem, the most likely usage is as an initramfs for the
kernel. This commit ensures that the kernel has initramfs support when
the rootfs cpio image format is chosen.
This will for example ensure that if the user selects the ISO9660
filesystem format (which uses a cpio initramfs), the kernel will have
proper support to load and use the initramfs.
It is worth mentionning that when BR2_TARGET_ROOTFS_INITRAMFS is
enabled, then BR2_TARGET_ROOTFS_CPIO is always enabled. That's why we
move the enabling of CONFIG_BLK_DEV_INITRD from the initramfs case to
the cpio case.

When a package A depends on config option B and toolchain option C, then
the comment that is given when C is not fulfilled should also depend on B.
For example:
config BR2_PACKAGE_A
depends on BR2_B
depends on BR2_LARGEFILE
depends on BR2_WCHAR
comment "A needs a toolchain w/ largefile, wchar"
depends on !BR2_LARGEFILE || !BR2_WCHAR
This comment should actually be:
comment "A needs a toolchain w/ largefile, wchar"
depends on BR2_B
depends on !BR2_LARGEFILE || !BR2_WCHAR
or if possible (typically when B is a package config option declared in that
same Config.in file):
if BR2_B
comment "A needs a toolchain w/ largefile, wchar"
depends on !BR2_LARGEFILE || !BR2_WCHAR
[other config options depending on B]
endif
Otherwise, the comment would be visible even though the other dependencies
are not met.
This patch adds such missing dependencies, and changes existing such
dependencies from
depends on BR2_BASE_DEP && !BR2_TOOLCHAIN_USES_GLIBC
to
depends on BR2_BASE_DEP
depends on !BR2_TOOLCHAIN_USES_GLIBC
so that (positive) base dependencies are separate from the (negative)
toolchain dependencies. This strategy makes it easier to write such comments
(because one can simply copy the base dependency from the actual package
config option), but also avoids complex and long boolean expressions.
