Upon investigation following are the only AVCs from audit logs blocking
us from running CephFS VFS integration.
. . .
type=AVC msg=audit(1706499792.666:8328): avc: denied { name_connect }
for pid=75570 comm="msgr-worker-1" dest=3300 scontext=system_u:system_r:smbd_t:s0
tcontext=system_u:object_r:unreserved_port_t:s0 tclass=tcp_socket permissive=1
. . .
Even though its misleading 'samba_load_libgfapi' seems to be the only
SELinux boolean that we require to run integration using VFS module for
Ceph in Samba under Enforcing mode. This is clear from the allow rules
defined for the boolean as follows:
$ sesearch -b samba_load_libgfapi -A
allow smbd_t packet_type:packet recv; [ samba_load_libgfapi ]:True
allow smbd_t packet_type:packet send; [ samba_load_libgfapi ]:True
allow smbd_t port_type:tcp_socket name_bind; [ samba_load_libgfapi ]:True
allow smbd_t port_type:tcp_socket name_connect; [ samba_load_libgfapi ]:True
