sysnetwork: allow systemd_networkd_t to read link file |
| 9 |
|
| 10 |
Per https://systemd.network/systemd.network.html, we can create a |
| 11 |
symlink pointing to /dev/null for systemd network configuration file. |
| 12 |
For example: |
| 13 |
$ ls -l /etc/systemd/network/80-wired.network |
| 14 |
lrwxrwxrwx. 1 root root 9 Mar 9 2022 /etc/systemd/network/80-wired.network -> /dev/null |
| 15 |
|
| 16 |
Fixes: |
| 17 |
avc: denied { read } for pid=211 comm="systemd-network" |
| 18 |
name="80-wired.network" dev="vda" ino=1477 |
| 19 |
scontext=system_u:system_r:systemd_networkd_t:s0-s15:c0.c1023 |
| 20 |
tcontext=system_u:object_r:net_conf_t:s0 tclass=lnk_file permissive=0 |
| 21 |
