The GCC option -fstack-protector-all is a security feature used to protect against stack-smashing attacks.
This option enhances the stack-smashing protection provided by -fstack-protector-strong.
-fstack-protector-all option applies stack protection to all functions, regardless of their characteristics.
While this offers the most comprehensive protection against stack-smashing attacks, it can significantly impact
the performance of the program because every function call includes additional checks for stack integrity.
This option can incur a performance penalty because of the extra checks added to every function call,
but it significantly enhances security, making it harder for attackers to exploit buffer overflows to execute arbitrary code.
It's particularly useful in scenarios where security is paramount and performance trade-offs are acceptable.

Until now, this feature was switched on via the kernel configuration

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.

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 buildbot builds, it makes sense to keep debug information reproducible,

Removes the standalone implementation of stack smashing protection
in gcc's libssp in favour of the native implementation available
in glibc and uclibc. Musl libc already uses its native ssp, so this
patch does not affect musl-based toolchains.

across all supported libc variants.
This also makes kernel-level stack smashing protection available

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
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.

Fixes: 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
cleaned up and updated.

Introduce a new option CONFIG_SIGNATURE_CHECK which defaults to the value
of CONFIG_SIGNED_PACKAGES and thus is enabled by default.
This option is needed to support building target opkg with enabled
signature verification while having the signed package lists disabled.
Our buildbots currently disable package signing globally in the
buildroot and SDK to avoid the need to ship private signing keys to
the build workers and to prevent the triggering of random key generation
on the worker nodes since package signing happens off-line on the master
nodes.
As unintended side-effect, updated opkg packages will get built with
disabled signature verification, hence the need for a new override option.
