ip_input.c ip_output.c
Log:
Assorted bridge+ipfw+dummynet fixes. The general goal of this set
of patches is to reduce the number of places where shared mbuf
clusters are modified.
In detail:
ip_fw.c:
modified the ip_fw_chk interface (so that it does not consume
the buffer unless strictly necessary).
ip_input.c, ip_output.c, bridge.c:
reflect above changes.
if_ethersubr.c:
avoid dereferencing pointers to an mbuf chain after it has been
freed. Also fix some bugs when interfaces are not part of
a bridging cluster.
ip_dummynet.[ch]
largely simplified the WF2Q+ implementation removing a redundant
data structrure.
bridge.[ch]
fix the forwarding loop to avoid modifying the packet when
possible.
