* refpolicy: add variant that builds modular policyW. Michael Petullo2020-11-091-0/+6
| | | | | | | | | 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. Signed-off-by: W.

* kernel: Activate KERNEL_MIPS_FP_SUPPORT for pistachio targetHauke Mehrtens2020-11-011-0/+1
| | | | | | | | | The pistachio target uses a MIPS CPU with FPU and OpenWrt uses a toolchain with hard FPU support. MIPS FPU support needs the FPU emulation code in the kernel.

* config: add KERNEL_LSM symbolPaul Spooren2020-09-031-11/+3
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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`. Signed-off-by: Paul Spooren <mail@aparcar.org>

* rb532: drop targetAdrian Schmutzler2020-09-021-1/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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.

* build: make prefix mapping of debug information optionalFelix Fietkau2020-08-061-0/+9
| | | | | | | | | | | | | | 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. Signed-off-by: Felix Fietkau <nbd@nbd.name>

| | | | | | | | | | | | | | | 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. Stack smashing protection configuration options are now uniform across all supported libc variants. This also makes kernel-level stack smashing protection available for x86_64 and i386 builds using non-musl libc. Signed-off-by: Ian Cooper <iancooper@hotmail.com>

* build: refactor JSON info files to `profiles.json`Paul Spooren2020-04-031-4/+5
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | JSON info files contain machine readable information of built profiles and resulting images. These files were added in commit 881ed09ee6e2 ("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.

* buildsystem: Make PIE ASLR option tristateHauke Mehrtens2020-01-131-4/+18
| | | | | | | | | | | | | | | | | | | | | | | | 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. Signed-off-by: Hauke Mehrtens <hauke@hauke-m.de> Acked-by: Petr Štetiar <ynezz@true.cz>

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.

* build: add buildinfo files for reproducibilityPaul Spooren2019-08-131-1/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | generate feeds.buildinfo and version.buildinfo in build dir after containing the feed revisions (via ./scripts/feeds list -sf) as well as the current revision of buildroot (via ./scripts/getver.sh). With this information it should be possible to reproduce any build, especially the release builds. Usage would be to move feeds.buildinfo to feeds.conf and git checkout the revision hash of version.buildinfo. Content of feeds.buildinfo would look similar to this: src-git routing https://git.openwrt.org/feed/routing.git^bf475d6 src-git telephony https://git.openwrt.org/feed/telephony.git^470eb8e ... Content of version.buildinfo would look similar to this: r10203+1-c12bd3a21b Without the exact feed revision it is not possible to determine installed package versions. Also rename config.seed to config.buildinfo to follow the recommended style of https://reproducible-builds.org/docs/recording/ Signed-off-by: Paul Spooren <mail@aparcar.org>
* config: introduce separate CONFIG_SIGNATURE_CHECK optionJo-Philipp Wich2019-08-061-0/+4
| | | | | | | | | | | | | | | | | | | 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. Signed-off-by: Jo-Philipp Wich <jo@mein.io>
