network-daemon leaks FDs when it runs udhcpc. These are seen as:
avc: denied { read write } for pid=1974 comm="udhcpc" path="socket:[15201]" dev="sockfs" ino=15201 scontext=system_u:system_r:dhcpc_t:s0 tcontext=system_u:system_r:network_daemon_t:s0 tclass=unix_stream_socket permissive=0
avc: denied { read write } for pid=1974 comm="udhcpc" path="/dev/argo_stream" dev="devtmpfs" ino=14802 scontext=system_u:system_r:dhcpc_t:s0 tcontext=system_u:object_r:argo_t:s0 tclass=chr_file permissive=0
Those started after commit 836c400 "Use system call instead of
spawning a shell", but that commit does fix an issue where dom0 doesn't
get an IP (udhcpc doesn't start).
Side-step this issue but removing launch of udhcpc. Dom0 will run
ifplugd to start it instead.
network-daemon starts udhcpc as:
udhcpc -b -i eth0 -p /var/run/udhcpc.pid
and ifup uses:
/sbin/udhcpc -R -b -p /var/run/udhcpc.eth0.pid -i eth0
So we gain -R - "Release IP on exit".
