The getrlimit call also fails, according to strace:
getrlimit(RLIMIT_CORE, 0xffffeb2acf88) = -1 EPERM (Operation not permitted)
setrlimit(RLIMIT_CORE, {rlim_cur=0, rlim_max=0}) = -1 EPERM (Operation not
permitted)
I don't have access to an aarch64 host running RHEL 7
directly, so my only testing is via the mock command from an
aarch74 Fedora 31 host.
Mock can use two styles of container, an old-style chroot or
new-style systemd-nspawn. Using chroot succeeds, while
systemd-nspawn fails.
I tested with CAP_SYS_RESOURCE added to the capability list
in the systemd-nspawn call, without success. From my
reading, that should work (thought shouldn't be needed as
we're not trying to raise the limit).
So it seems like a bug either in systemd-nspawn or a lower
level component like glibc or the kernel with RHEL 7 on
aarch64, as you suggested.
