kernel: Use new symbol to deactivate MIPS FPU support

2020-02-28T16:50:46Z

With kernel 5.4 the upstream kernel supports deactivating the FPU support on MIPS. Use this new upstream feature instead of our older patch which was removed when porting the kernel patches to kernel 5.4. This way both options are set which should work for older kernel versions and also new ones. Signed-off-by: Hauke Mehrtens

base-files: add all buildinfo with INCLUDE_CONFIG

2020-02-27T11:14:09Z

CONFIG_INCLUDE_CONFIG option is helpful for being able to rebuild the exact same firmware as you see on a live OpenWRT instance, but it's crucially missing feeds information, so we can't rebuild the exact same package versions. This commit fixes this by adding the remaining feeds (and version) buildinfo files to the image. Signed-off-by: Xu Wang

brcm2708: rename target to bcm27xx

2020-02-14T13:10:51Z

This change makes the names of Broadcom targets consistent by using the common notation based on SoC/CPU ID (which is used internally anyway), bcmXXXX instead of brcmXXXX. This is even used for target TITLE in make menuconfig already, only the short target name used brcm so far. Despite, since subtargets range from bcm2708 to bcm2711, it seems appropriate to use bcm27xx instead of bcm2708 (again, as already done for BOARDNAME). This also renames the packages brcm2708-userland and brcm2708-gpu-fw. Signed-off-by: Adrian Schmutzler Acked-by: Álvaro Fernández Rojas

buildsystem: Make PIE ASLR option tristate

2020-01-13T14:34:36Z

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 Acked-by: Petr Štetiar

libcxx: Depenency fixes

2019-12-23T11:08:23Z

Don't build with uClibc-ng. It's totally unsupported as several functions are missing. Make the musl libc support conditional. Fix hash with make check FIXUP=1. Apparently I based the Makefile off of libedit and forgot to fix the hash. Signed-off-by: Rosen Penev Fixes: 856ea2bad3b3 ("libcxx: Add package")

libcxx: Add package

2019-12-22T23:22:07Z

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. Runtime tested with gddrescue, gdisk, dcwapd, bonnie++, and aircrack-ng on a TP-Link Archer C7v2. Signed-off-by: Rosen Penev
