Created attachment 397686 [details, diff] longrun-0.9-r4 ebuild patch app-admin/longrun fails to compile with musl on hardened because it uses loff_t in longrun.c. Can be fixed by adding "append-flags -D_GNU_SOURCE" in ebuild. Attached diff for your convenience.

The loff_t can be safely replaced by off_t. That's the type used by pread() and pwrite(). The relevant code is introduced by the patch from Debian, which seems to be effectively the upstream for this package. It would be good to try to get Debian to fix the patch.
Alright. I'll contact the Debian maintainer and get his input.

Correct? Correct. read_msr, write_msr and read_cpuid originally takes a "long address" but the Debian patch replaces it with "loff_t address". I have submitted the patch to the Debian maintainer but haven't got a response yet.
I add a patch to change loff_t to off_t. The only consumer of off_t address in those functions is pread/pwrite() which take off_t as Felix said. I'm going to close this for now, but redirect the debian maintainer here.
Actually I'm reopening so the workflow can indicate that its in the overlay but still has to be pushed upstream (in this case to the debian maintainer).
