Subject: pflog0 showing up in my vnet jails
To: freebsd-pf@freebsd.org
User-Agent: NeoMutt/20201127
I noticed this evening that pflog0 is propagated into my vnet-based jails
(12.2-RELEASE) and I'm somewhat surprised to see it there.
My host's /etc/rc.conf simply has `pflog_enable=3D"YES"`, so nothing too
esoteric. My /etc/jail.conf doesn't do anything with pflog0 for the jails, =
so
the fact that it shows up _feels_ like a bug, from within a jail:
# ifconfig
lo0: flags=3D8049<UP,LOOPBACK,RUNNING,MULTICAST> metric 0 mtu 16384
options=3D680003<RXCSUM,TXCSUM,LINKSTATE,RXCSUM_IPV6,TXCSUM_IPV=
6>
inet6 ::1 prefixlen 128
inet6 fe80::1%lo0 prefixlen 64 scopeid 0x1
inet 127.0.0.1 netmask 0xff000000
groups: lo
nd6 options=3D21<PERFORMNUD,AUTO_LINKLOCAL>
pflog0: flags=3D0<> metric 0 mtu 33160
groups: pflog
epair2b: flags=3D8843<UP,BROADCAST,RUNNING,SIMPLEX,MULTICAST> metric 0 =
mtu 1500
options=3D8<VLAN_MTU>
ether 02:c4:52:c8:47:0b
inet 10.0.1.4 netmask 0xffffff00 broadcast 10.0.1.255
groups: epair
media: Ethernet 10Gbase-T (10Gbase-T <full-duplex>)
status: active
nd6 options=3D29<PERFORMNUD,IFDISABLED,AUTO_LINKLOCAL>
#=20
Fortunately, when I tcpdump that device from within the jail, it has none o=
f
the host pflog0's entries being reported.
Regardless, should I file this as a bug?
Cheers
