Since Buildroot commit [1] "package/elfutils: bump to version 0.192"
elfutils fails to build on Aarch64 with toolchain including Kernel older
than version 5.0. Error shows:
aarch64_initreg.c: In function 'aarch64_set_initial_registers_tid':
aarch64_initreg.c:61:24: error: storage size of 'pac_mask' isn't
known
61 | struct user_pac_mask pac_mask;
| ^~~~~~~~
elfutils 0.192 introduced a Aarch64 pointer authentication support in
upstream commit [2].
For reference, the user_pac_mask structure was introduced in Kernel
upstream commit [3], included in Kernel v5.0.
This is fixed in the upstream [4] so bring that patch in.
Fixes:
- e.g https://autobuild.buildroot.org/results/5156901a73be52ce8ffbf10729e6852499a300be/
- 4/6 of the failures here: https://autobuild.buildroot.org/?reason=elfutils-0.192&arch=aarch64
