This is a neat project, but offers no benefit to OpenWrt. The initial
reason for it was to be a replacement for libstdcpp as it is smaller

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`.

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.

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.

This tristate choose allows to select to build only some applications

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

Our buildbots currently disable package signing globally in the

Currently we're producing unusable x86 combined squashfs images

thus providing very small space for the overlay filesystem, leading to
the following with OpenWrt 18.06.1 r7258-5eb055306f images on x86 QEMU:
root@(none):/# mount | egrep 'root|overlay'
/dev/root on /rom type squashfs

Commit eae6cac6a3 ("lantiq: add support for AVM FRITZ!Box 7362 SL"), but
one needs an initramfs image to flash OpenWrt from stock firmware (as
described in the commit log). This patch has the initramfs image built
by default.
Thanks to blogic (for pointing to the FEATURES declaration in the target
Makefiles) and Musashino on the forum for suggesting
config/Config-images.in needed editing too. While at it, reorder the
TARGET_INITRAMFS_COMPRESSION_LZMA declarations alphabetically.
This patch will result in initramfs images for all lantiq subtargets
that have the ramdisk flag set. I tested on the falcon and ase
subtargets, which lack that flag, to confirm they don't produce any
initramfs images with this patch - which they do not.
Given the limited scope of the lantiq (sub)target(s), blogic indicated
this should be OK.

perf/core: Rename CONFIG_[UK]PROBE_EVENT to CONFIG_[UK]PROBE_EVENTS
We have uses of CONFIG_UPROBE_EVENT and CONFIG_KPROBE_EVENT as
well as CONFIG_UPROBE_EVENTS and CONFIG_KPROBE_EVENTS.
Consistently use the plurals.
So I'm adding this plural option in order to make kconfig happy and stop
asking about it if kernel is compiled with verbose logging:
Enable kprobes-based dynamic events (KPROBE_EVENTS) [Y/n/?] (NEW)

Unreachable config symbols:

When CGROUP block io is enabled a new symbol is exposed and needs to
be set or unset else kernel oldconfig hangs waiting for input during
normal OpenWrt builds. Therefore add sane defaults for this symbol
in that case. Also, the defaults brcm2708 are different than generic
defaults because the platform's defconfig enables BLK_DEV_THROTTLING
by default (in defconfig config from the patches used to match
upstream's kernel, not in OpenWrt config-4.xx).

This patch adds the boot-part feature which enables the brcm2708
target move from the custom boot partition size config option to
the generic CONFIG_TARGET_KERNEL_PARTSIZE.
Note:
For people using custom images: Just like with
CONFIG_TARGET_ROOTFS_PARTSIZE changing the value
can cause sysupgrade to repartition the device!
Make sure to have a backup in this case.

Add a new config option to allow to select the default compile
optimization level for the kernel.
Select the optimization for size by default if the small_flash feature is
set. Otherwise "Optimize for performance" is set.
Add the small_flash feature flag to all (sub)targets which had the
optimization for size in their default kernel config.
Remove CC_OPTIMIZE_FOR_* symbols from all kernel configs to apply the new
setting.
Exceptions to the above are:
- lantiq, where the optimization for size is only required for the
xway_legacy subtarget but was set for the whole target
- mediatek, ramips/mt7620 & ramips/mt76x8 where boards should have
plenty of space and an optimization for size doesn't make much sense
- rb532, which has 128MByte flash

Configure variable SSP_SUPPORT is ambiguous for packages (tor, openssh,
avahi, freeswitch). It means 'toolchain supporting SSP', but for toolchain
and depends it means 'build gcc with libssp'.
Musl no longer uses libssp (1877bc9d8f), it has internal support, so
SSP_SUPPORT was disabled leading some package to not use SSP.
No information why Glibc and uClibc use libssp, but they may also provide
their own SSP support. uClibc used it own with commit 933b588e25 but it was
reverted in f3cacb9e84 without details.
Create an new configure GCC_LIBSSP and automatically enable SSP_SUPPORT
if either USE_MUSL or GCC_LIBSSP.

Introduce a configuration option to build a "hardened" OpenWrt with
ASLR PIE support.
Add new option PKG_ASLR_PIE to enable Address Space Layout Randomization (ASLR)
by building Position Independent Executables (PIE). This new option protects
against "return-to-text" attacks.
Busybox need a special care, link is done with ld, not gcc, leading to
unknown flags. Set BUSYBOX_DEFAULT_PIE instead and disable PKG_ASLR_PIE.
If other failing packages were found, PKG_ASLR_PIE:=0 should be added to
their Makefiles.

Symbol CONFIG_INITRAMFS_FORCE allows to ignore the value passed by the

By default, all symbols containing INITRAMFS are wiped from the final

Add support for this symbol, as the build will stop otherwise
