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

Buildroot is a simple, efficient and easy-to-use tool to generate embedded Linux systems through cross-compilation. The documentation can be found in docs/manual. You can generate a text document with 'make manual-text' and read output/docs/manual/manual.text. Online documentation can be found at http://buildroot.org/docs.html To build and use the buildroot stuff, do the following: 1) run 'make menuconfig' 2) select the target architecture and the packages you wish to compile 3) run 'make' 4) wait while it compiles 5) find the kernel, bootloader, root filesystem, etc. in output/images You do not need to be root to build or run buildroot. Have fun! Buildroot comes with a basic configuration for a number of boards. Run 'make list-defconfigs' to view the list of provided configurations. Please feed suggestions, bug reports, insults, and bribes back to the buildroot mailing list: buildroot@buildroot.org You can also find us on #buildroot on OFTC IRC. If you would like to contribute patches, please read https://buildroot.org/manual.html#submitting-patches
