* toolchain: glibc: Update to version 2.34Hauke Mehrtens2022-01-073-8/+8
| | | | | | | | | | | | glibc version 2.34 does not provide versioned shared libraries any more, it only provides shared libraries using the ABI version. Do not try to copy them any more. The functions from libpthread and librt were integrated into the main binary, the libpthread.so and librt.so are only used for backwards compatibility any more.

* toolchain: musl: disable crypt size hack by defaultPetr Štetiar2021-12-271-3/+4
| | | | | | | | | | | | | | | | Enable this option and thus re-include crypt() support for the SHA256, SHA512 and Blowfish ciphers on all devices. According to commit 9365745f8e7b ("musl: add a hack to remove unused crypt() algorithms, saves ~14k after lzma") it should add about ~14k to the resulting image, which seems to be a reasonable size increase for consistent crypt() support. Decided to not remove this hack completely as it might be still useful for people trying to fit custom images onto smaller devices and the patch is rather simple so we can afford to keep it for now.

* toolchain/gcc: use ELFv2 ABI on ppc64 with muslStijn Tintel2021-12-211-0/+1
| | | | | | | | | | | | | | At configuration time, gcc assumes that ppc64be targets use the ELFv1 ABI, and ppc64le targets use the ELFv2 ABI. However, musl libc does not support the ELFv1 ABI on ppc64 at all, regardless of the endianness. Therefore, when building for a ppc64 arch and with musl libc, instruct gcc to use the ELFv2 ABI. See https://gcc.gnu.org/bugzilla/show_bug.cgi?id=93157 for more info. Signed-off-by: Stijn Tintel <stijn@linux-ipv6.be> Reviewed-by: Rui Salvaterra <rsalvaterra@gmail.com>

| | | | | | | | | | | | | | | | | | | | This patch has been upstream since GCC 10. Dragan Mladjenovic (2): Emit .note.GNU-stack for soft-float linux targets. Emit .note.GNU-stack for hard-float linux targets.
