Adjust default_print() to not run over snapend. Kill default_print_unaligned() and adjust default_print() to also work with unaligned buffers. There is no need for two functions doing the same thing. Pass the right length in nsh_print to default_print(). Fixes on place that makes tcpdump crash. Reported by Peter J. Philipp (pjp at delphinusdns dot org) OK mbuhl@

add initial support for handling geneve packets. it's like vxlan, but different. the most interesting difference to vxlan is that the protocol adds support for adding optional metadata to packets (like nsh). this diff currently just skips that stuff and just handles the payload. for now.

rework ppp, pptp, and gre parsing. this started cos i was looking at pptp, which came out like this: 23:52:00.197893 call 24 seq 7: gre-ppp-payload (gre encap) 23:52:00.198930 call 1 seq 7 ack 7: gre-ppp-payload (gre encap) now it looks like this: 23:52:00.197893 20.0.0.2 > 20.0.0.1: pptp callid 24 seq 7: 17.1.1.122 > 40.0.0.2: icmp: echo request 23:52:00.198930 20.0.0.1 > 20.0.0.2: pptp callid 1 seq 7 ack 7: 40.0.0.2 > 17.1.1.122: icmp: echo reply the big improvement in ppp parsing is it stops parsing based on what the ppp headers say, rather than what bytes have been captured. this also adds parsing of EAP packets. DLT_PPP_SERIAL is now recognised and printed. gre now prints the outer addresses always, not just when it's encapsulated by ipv6 or -v is passed to tcpdump. ok sthen@

tcpdump is two-process privsep. the packet processor pid is initialized on a socketpair, and then only does byte analysis. it can be protected using a "stdio" tame request. an successfull attack against it will find it cannot open files nor sockets, and faces various other limitations described in the tame(2) manual page. the monitor process can be restricted to "malloc cmsg inet ioctl dns rpath". that sounds like a large subset, but notice it cannot create or write files. maybe this set can be wittled down by hoisting more initialization code upwards? with help from canacar a while back.

OK, this is horrible. stdio safety in a signal handler, requires that we make the regular data stream non-buffered. This drastically reduces tcpdump performance. Let us commit this, and see how people react. But realistically, without this, we cannot gaurantee that the tail of a file is correct on signal.
