usr.sbin/ospf6d: lsupdate.c
Log message:
Same fix for ospfd lsupdate.c applies in ospf6d as well.
Do not use the pointer returned by ibuf_reserve() after calling another
ibuf function. After the call the internal buffer may have moved by realloc()
and so the pointer is invalid. Instead use ibuf_size() to get the current
offset in the buffer and use ibuf_seek() later on to write back the updated
lsa age into the buffer at the right spot.
This fixes an issue seen by Richard Chivers on routers with many passive
interfaces.
