Description of problem: fapolicyd rules are not applied in systemd services running with dynamic user Version-Release number of selected component (if applicable): fapolicyd-1.1.4-4.fc38.x86_64 fapolicyd-selinux-1.1.4-4.fc38.noarch How reproducible: I only tried on Rawhide Steps to Reproduce: 1. cp /usr/bin/id /usr/bin/id2 2. systemd-run --pipe -p User=haproxy bash -c 'id ; id2' 3. systemd-run --pipe -p DynamicUser=yes bash -c 'id ; id2' Actual results: in 3.: # systemd-run --pipe -p DynamicUser=yes bash -c 'id ; id2' Running as unit: run-u86.service uid=62294(run-u86) gid=62294(run-u86) groups=62294(run-u86) context=system_u:system_r:initrc_t:s0 uid=62294(run-u86) gid=62294(run-u86) groups=62294(run-u86) context=system_u:system_r:initrc_t:s0 Expected results: similar to 2., id2 should fail: Running as unit: run-u81.service uid=982(haproxy) gid=981(haproxy) groups=981(haproxy) context=system_u:system_r:initrc_t:s0 /usr/bin/bash: line 1: /usr/bin/id2: Operation not permitted Additional info:
For some reason, fanotify doesn't see the open/execute request at all. It sees systemd-run start and after that it goes dark.
Thanks for pointing out this problem. Upstream has merged a patch that allows fapolicyd to see events on bind mount or overlayfs partitions. However, there are limitations on what can be controlled when containers are used. In any event, try the 1.1.7 version when it becomes available.
