Description Paul Whalen 2021-05-03 20:49:32 UTC
Description of problem:

Attempting to run dnf in a container on Fedora 34 armv7 fails with:

STEP 2: RUN /usr/bin/dnf install -y httpd 
The futex facility returned an unexpected error code.
container exited on illegal instruction
Error: error building at STEP "RUN /usr/bin/dnf install -y httpd": error while running runtime: exit status 1

In the logs:

May 03 19:20:30 rpi2-1 audit[3036]: SECCOMP auid=1000 uid=1000 gid=1000 ses=1 subj=system_u:system_r:container_t:s0:c201,c466 pid=3036 comm="dnf" exe="/usr/bin/python3.9" sig=0 arch=40000028 syscall=422 compat=0 ip=0xb6b59f7c code=0x50000

syscall 422 on armv7 is - futex_time64

Adding 'futex_time64' to the  '/usr/share/containers/seccomp.json' allows dnf to run as expected. 

Version-Release number of selected component (if applicable):
