Tony Ambardar 531e0399cd build: add option KERNEL_DEBUG_INFO_BTF
Generate BTF (BPF Type Format) information from DWARF debug info. This is
embedded in the kernel and exported via sysfs as /sys/kernel/btf/vmlinux.
BTF data enhances kernel portability and introspection for BPF programs.

Selecting this also enables the dwarves host package which provides the
pahole tool used for BTF encoding.

Test using: "bpftool btf dump file /sys/kernel/btf/vmlinux format c"

This needs to depend on KERNEL_DEBUG_INFO_REDUCED not being set,
otherwise we can enable both KERNEL_DEBUG_INFO_BTF and
KERNEL_DEBUG_INFO_REDUCED, which will result in undefined behaviour.

buildsystem: add CONFIG_SECCOMP
Until now, this feature was switched on via the kernel configuration
option KERNEL_SECCOMP.

The follwing change a7f794cd2a now requires that
the package procd-seccomp must also enabled for buildinmg.

However, this is not the case we have no dependency and the imagebuilder
cannot build the image, because of the implicit package selection.

This change adds a new configuration option CONFIG_SECCOMP.
The new option  has the same behaviour as the configuration
option CONFIG_SELINUX.

If the CONFIG_SECCOMP is selected then the package procd-seccomp and
KERNEL_SECCOMP is enabled for this build.

Stijn Tintel 57807f50de base-files: add option to make /var persistent
In OpenWrt, /var is symlinked to /tmp by default. This is done to reduce
the amount of writes to the flash chip, which often have not the
greatest durability. As a result, things like DHCP or UPnP lease files,
are not persistent across reboots.

Since OpenWrt can run on devices with more durable storage, it makes
sense to have an option for a persistent /var. Add an option to make
/var persistent. When enabled, /var will no longer be symlinked to /tmp,
but /var/run will be symlink to /tmp/run, as it should contains only
files that should not be kept during reboot. The option is off by
default, to maintain the current behaviour.

Daniel Golle 330bd380e8 image: allow building FIT and uImage with ramdisk
Instead of embedding the initrd cpio archive into the kernel, allow
for having an external ramdisk added to the FIT or uImage.
This is useful to overcome kernel size limitations present in many
stock bootloaders, as the ramdisk is then loaded seperately and doesn't
add to the kernel size. Hence we can have larger ramdisks to host ie.
installers with all binaries to flash included (or a web-based
firmware selector).
In terms of performance and total size the differences are neglectible.

  ip -6 route add  2003::/64 dev eth0 encap seg6 mode encap \
    segs 2001::1,2002::2

However, in the current state this interface is disabled as you can

 "Strip non-essential /proc functionality to reduce code size"

Tools like netstat use the snmp/6 interface to collect interface
statistics. Some prometheus exporters also mention this:
- prometheus-collectors/netstat.lua
- prometheus-collectors/snmp6 (still a PR)
- collectd/snmp6 (still a PR)

 default y if SMALL_FLASH

I would like to enable this by default for all 5.4 kernels, so i can use the new io_uring samba-4.12.x vfs module by default.

The associated liburing was already submitted and merged.
The kernel + liburing was tested on ARM/mvebu via samba4 vfs_io_uring module and i have no issues so far.

Some extra reads on it and why we should enable it by default, since i expect more packages to use this in the future.

This adds a variant of refpolicy that builds the modular form of the
policy. While this requires more memory on the target device, along with
some tricks to deal with OpenWrt's volatile /var directory, it is useful
for experiementing with SELinux policy.

Paul Spooren f922a3e00e config: add KERNEL_LSM symbol
The LSM (Linux security mechanism) list is the successor of the now
legacy *major LSM*. Instead of defining a single security mechanism the
LSM symbol is a comma separated list of mechanisms to load.

Until recently OpenWrt would only support DAC (Unix discretionary access
controls) which don't require an additional entry in the LSM list. With
the newly introduced SELinux support the LSM needs to be extended else
only a manual modified Kernel cmdline (`security=selinux`) would
activate SELinux.

As the default OpenWrt Kernel config sets DAC as default security
mechanism, SELinux is stripped from the LSM list, even if
`KERNEL_DEFAULT_SECURITY_SELINUX` is activated. To allow SELinux without
a modified cmdline this commit sets a specific LSM list if
`KERNEL_SECURITY_SELINUX` is enabled.

The upstream Kconfig adds even more mechanisms
(smack,selinux,tomoyo,apparmor), but until they're ported to OpenWrt,
these can be ignored.

To compile SELinux Kernel support but disable it from loading, the
already present options `KERNEL_SECURITY_SELINUX_DISABLE` or
`KERNEL_SECURITY_SELINUX_BOOTPARAM` (with custom cmdline `selinux=0`)
can be used. Further it's possible to edit `/etc/selinux/config`.

Adrian Schmutzler 94198e2a1c rb532: drop target
This target is still on kernel 4.14, and recent attempts to move it to
kernel 5.4 have not led to success. The device tester reported that it
wouldn't boot with the following messages:

From sysupgrade:

  Press any key within 4 seconds to enter setup....
  loading kernel from nand... OK
  setting up elf image... OK
  jumping to kernel code

At this point the system hangs.

From CompactFlash:

  Press any key within 4 seconds to enter setup....
  Booting CF
  Loading kernel... done
  setting up elf image... kernel out of range kernel loading failed

The tester reported that the same was observed with current master
(kernel 4.14) as well. This looks like some kernel size restriction.

Since this target is quite old and only supports one device, and since
nobody else seemed interested in working on this for quite some time,
I decided to not put further work into analyzing the problem and drop
this together with the other 4.14-only targets.

Remapping the local build path in debug information makes debugging
using ./scripts/remote-gdb harder, because files no longer refer to the full
path on the build host.

For local builds, debug information does not need to be reproducible,
since it will be stripped out of packages anyway.

For buildbot builds, it makes sense to keep debug information reproducible,
since the full path is not needed (nor desired) anywhere.

Paul Spooren 07449f692c build: refactor JSON info files to `profiles.json`
JSON info files contain machine readable information of built profiles
and resulting images. These files were added in commit 881ed09ee6
("build: create JSON files containing image info").

They are useful for firmware wizards and script checking for
reproducibility.

Currently all JSON files are stored next to the built images, resulting
in up to 168 individual files for the ath79/generic target.

This patch refactors the JSON creation to store individual per image
(not per profile) files in $(BUILD_DIR)/json_info_files and create an
single overview file called `profiles.json` in the target directory.

Storing per image files and not per profile solves the problem of
parallel file writes. If a profiles sysupgrade and factory image are
finished at the same time both processes would write to the same JSON
file, resulting in randomly broken outputs.

Some target like x86/64 do not use the image code yet, resulting in
missing JSON files. If no JSON info files were created, no
`profiles.json` files is created as it would be empty anyway.

As before, this creation is enabled by default only if `BUILDBOT` is set.

Tested via buildroot & ImageBuilder on ath79/generic, imx6 and x86/64.

* Make iso images x86 specific and drop their definition as root

* Convert image creation process to generic code specified in image.mk.

This tristate choose allows to select to build only some applications
with PIE enabled. On MIPS binaries are getting about 30% bigger when PIE
is activated for the, which is a huge increase.

Network exposed applications like dnsmasq should then be build with PIE
enabled, but some applications which are normally not parsing data from
the network do not have it activated. The regular option should give a
good trade off between extra flash and RAM memory usage and security.

This changes the default from building no applications with PIE to build
some specifically marked applications with PIE enabled. This option is
only activated for targets with bigger flash and RAM to not consume
extra memory on the very small targets. On SDK builds the Regular option
should always be selected, because some tiny targets share the
applications with big targets and only the images for the tiny targets
should contain the none PIE applications, but the images for the normal
targets should use PIE. The shared packages should always use PIE when
it should be normally activated.

Rosen Penev 856ea2bad3 libcxx: Add package
Currently in OpenWrt, there are two libc++: libstdcpp and uClibc++. The
former is huge and the latter supports only C++98 with some basic support
for C++11. Those C++ versions seem to be specific to the compiler version

libcxx supports C++11 and above while being much smaller than libstdcpp.
On mt7621, these are the sizes of the ipks that I get:

libstdcpp: 460786
libcxx: 182881
uClibc++:67720

libcxx is faster than uClibc++ and is under active development as part of
the LLVM project while uClibc++ is effectively dead.

This PR modifies uclibc++.mk to expose the make menuconfig option. Further
cleanup is beyond the scope of this PR. What that means is, this is not
used by default.

A g++-libcxx wrapper based on the uClibc++ one was added. Works the same
way.

Compile tested with all packages that use uclibc++.mk in their Makefiles
under mipsel_24kc. kismet fails compilation but that package needs to be

Paul Spooren e78c1baa9f rules: allow arbitrary log destination
Add option BUILD_LOG_DIR to menuconfig to change log destination.

The mix-up of *DIR* and *FOLDER* is confusing however.

build: set TARGET_ROOTFS_PARTSIZE to make combined image fit in 128MB
Change TARGET_ROOTFS_PARTSIZE from 128 to 104 MiB, so the whole image
(bootloader + boot + root) will fit on a 128MB CF card by default.

With these settings, the generated images (tested on x86-generic and
x86-64) have 126,353,408 bytes; the smallest CF card marketed as "128MB"
that I found a datasheet for (a Transcend TS128MCF80) has 126,959,616
bytes.

Daniel Golle 7cc22d72e9 config: kernel: only enable container features if !SMALL_FLASH
KERNEL_DEVPTS_MULTIPLE_INSTANCES and KERNEL_POSIX_MQUEUE were
previously enabled by default only if KERNEL_LXC_MISC was selected.
KERNEL_LXC_MISC was enabled only if the SMALL_FLASH (anti-)feature
was not selected.
Now that KERNEL_LXC_MISC no longer exists, make sure that those
options are also only enabled by default for !SMALL_FLASH targets.

Yousong Zhou 4f94a331e1 config: kernel: remove KERNEL_LXC_MISC
Kernel features are neutral.  The two cascaded features can also be
useful for other container related tools

It's also less error-prone if only kconfig symbols from the kernel are
prefixed KERNEL_

Yousong Zhou 083bb9b6a4 config: kernel: add KERNEL_X86_VSYSCALL_EMULATION
Binaries in container images may need this.  E.g. nginx:1.7.9 used in
k8s default deployment manifest file for demostration [1]
