OK; after:
Script started on Tue Nov 3 08:22:37 2015
g1-252(10.2-S)[1] (cd /S4/usr/src/ && svn diff -c 290334 >/tmp/r290334)^M
g1-252(10.2-S)[2] (cd /S4/usr/src/ && svn patch --reverse-diff /tmp/r290334=
)^M
U sys/netpfil/ipfw/ip_fw_sockopt.c
U sys/netpfil/ipfw/ip_fw_table.c
g1-252(10.2-S)[3] exit
followed by a "make buildkernel", I now have:
FreeBSD localhost 11.0-CURRENT FreeBSD 11.0-CURRENT #232 r290334M/290334:1=
100086: Tue Nov 3 08:27:20 PST 2015 root@localhost:/common/S4/obj/usr/=
src/sys/CANARY amd64
and
localhost(11.0-C)[3] ifconfig wlan0=20
wlan0: flags=3D8843<UP,BROADCAST,RUNNING,SIMPLEX,MULTICAST> metric 0 mtu 15=
00
ether 00:24:d6:7a:03:ce
inet 198.135.49.33 netmask 0xfffffc00 broadcast 198.135.51.255=20
=2E..
as I type, and IPFW is isn use
at a *guess*, we'll need a bit more effort to keep "found" and
"ci->object_opcodes" in sync, at least by the time the KASSERT on
src/sys/netpfil/ipfw/ip_fw_table.c:3395 looks at the values.
Thanks!
Peace,
david
