he 70a24dc7c0 Change from sprintf() to snprintf() where we may print externally 
supplied data of unknown length.
Changes adapted from FreeBSD-SA-00:61.
 2000-10-31 12:17:07 +00:00
is d8302e2d73 More format string cleanups by sommerfeld. 2000-10-11 20:23:46 +00:00
itojun 70875bf54c add new cipher DOI # including AES. 
add CR payload decoder.  fix ID payload decode.
have __attribute__((__packed__)) for align picky arch
(tcpdump.org code has better fix with lots of memcpy, however,
tcpdump.org version needs more verfication).

basically, sync with kame tree.

fvdl 63d43d2078 Fix 2 cases of wrong checks for sufficient bytes, causing output 
to be not as verbose as it should have been.

itojun afa5315364 correct typo in #define. ICMP6_NI_SUCESS -> SUCCESS (notice missing C). 
sync with kame.

itojun 058e85bfc6 we shouldn't use "(ip + 1)" to detect intermediate headers (AH/ESP). 
we should use ip_p == IPPROTO_TCP/UDP.

itojun bec9b9854d IPv6 UDP header checksum. 2000-08-01 17:35:18 +00:00
itojun 1c0969bf27 use of ip_p is irrelevant in tcp_cksum, as we may have AH/ESP inbetween. 2000-08-01 17:34:00 +00:00
itojun d9bba2ca98 some merge from tcpdump.org code. 
- print-telnet.c: do not print control character
- print-icmp6.c: improve icmp6 node information printing
  (we need to at least meet our kernel code!)
- update dhcp6 printing to 15 draft (14 and 15 are totally incompatible)
- add safeputc() and safeputs() into util.c

sjg 6c501163d3 missing P in \fP 1999-10-11 12:37:43 +00:00
is a7c7586cf6 First part of ARCnet support. 
Matching for anything won't work (as we need to teach the stuff about
variable length link level headers), but printing is fine.
 1999-10-05 20:37:21 +00:00
sjg dbb9ca2738 Add printing of TELNET options (with -v) and hex/ascii (-X).

nathanw 42aa7dd2a0 Since this uses memcpy(), we need to pull in string.h to make this compile 
on the alpha. Now confirmed working on that platform.
 1999-06-25 03:22:35 +00:00
sommerfeld 4b5ec636eb Fix obvious LP64 and aliasing bogons in checksum verification code. 
Should fix spurious "bad checksum" errors on alpha, but not yet tested
on that platform.
 1999-06-25 03:08:02 +00:00
