096b0d6c6e In udp_output(), sanity check the length of the packet to be transmitted.
If it's larger than IP_MAXPACKET, return an error condition.

e55c8a9c7e Before concatenating frags, sanity check the length of the packet. If it's

65c188b3c7 Make length and offset fields unsigned. From Kevin M. Lahey <kml@nas.nasa.gov>
Add a counter to IP stats, to count packets which are discarded on the
grounds that they are too large.

08899f4a1b Fix a mbuf leak in ip_output().
Scenario: If ip_insertoptions() prepends a new mbuf to the chain, the
bad: label's m_freem(m0) still would free only the original mbuf chain
if the transmission failed for, e.g., no route to host; resulting in
one lost mbuf per failed packet. (The original posting included a
demonstration program).

Original report of this bug was by jinmei@isl.rdc.toshiba.co.jp
(JINMEI Tatuya) on comp.bugs.4bsd.

17fcad6b2c commit fix in pr 2772 -- the IP input code was assuming that the
reserved (must be zero) flag must necessarily be zero. We now define
an IP_RF (by analogy to IP_DF and IP_MF) and mask it out when necessary.

f5a52c4260 Move an #ifdef _KERNEL up above all the packet filter stuff. This
could very well break the packet filter stuff, but it will make things
like rcp.c compile, and rcp.c should not need to include sys/mbuf.h
to do so...

a08c95305d fixes/new stuff:
[1] if user tries to enter in a bogus PVC don't leave it in the routing
        table ... remove it
[2] change ioctl arg to include rxso for lower layer
[3] add hooks (inside "NATM" ifdef) for native mode atm sockets so that
        they don't clash with IP PVCs.   [i am still debugging the native
        mode atm socket protosw code]

4edabe2501 Changed struct ifnet to have a pointer to the softc of the underlying
device and a printable "external name" (name + unit number), thus eliminating
if_name and if_unit.  Updated interface to (*if_watchdog)() and (*if_reset)()
to take a struct ifnet *, rather than a unit number.
