Description Paul Whalen 2023-07-21 15:44:30 UTC
Running `fdo-client` on an F38 IoT system fails to make configured changes due to selinux denials:

type=AVC msg=audit(1689703785.900:181): avc:  denied  { getattr } for  pid=1279 comm="fdo-client-linu" path="/boot/device-credentials" dev="vda2" ino=24 scontext=system_u:system_r:fdo_t:s0 tcontext=system_u:object_r:unlabeled_t:s0 tclass=file permissive=0
type=AVC msg=audit(1689704283.118:192): avc:  denied  { getattr } for  pid=1522 comm="fdo-client-linu" path="/etc/device-credentials" dev="dm-1" ino=40315 scontext=system_u:system_r:fdo_t:s0 tcontext=system_u:object_r:unlabeled_t:s0 tclass=file permissive=0

Changing to Permissive allows the fdo-client to make the configured changes, sample AVC's listed below(full list attached):

type=AVC msg=audit(1689704302.288:202): avc:  denied  { read } for  pid=1534 comm="fdo-client-linu" name="passwd" dev="dm-1" ino=37071 scontext=system_u:system_r:fdo_t:s0 tcontext=system_u:object_r:passwd_file_t:s0 tclass=file permissive=1

Reproducible: Always

Steps to Reproduce:
1. Start the fdo-client-linuxapp.service on a host with selinux in enforcing
2. FDO client fails to make configuration changes


Expected Results:  
Configuration changes to the running system.
