2007-06-27When aligning buffers correctly handle the case where theCan Erkin Acar
buffers overlap, which happens on 64 bit archs, when handling encapsulated packets. Reported and tested by Jurjen Oskam additional testing by Stuart Henderson and todd@, ok henning@
2007-06-21Print leading zeros in MAC addresses. Initial diff from StanislavRay Lai
Kruchinin, idea to use ether_ntoa from Claudio Jeker. OK canacar, idea OK henning, jasper, and tedu.
2007-06-14Print communities in a nicer format and include a missing well-known one.Claudio Jeker
This is mostly from Stuart Henderson. OK canacar@
2007-06-14The External Route Tag for AS-External-LSAs can be an arbitrary 32bitReyk Floeter
value and doesn't need to be an IPv4 address. It is more like a vendor-specific field. as discussed with claudio after looking into rfc2328

pfsync_state (as in pfctl, but in network byte order). ok henning@ toby@ pyr@
2007-05-29Do not change snaplen when parsing a netflow packetCan Erkin Acar
2007-05-27Additional truncation checks, mostly from tcpdump.org,Can Erkin Acar
and remove some unused hlen assignments found by lint from Stuart Henderson, reviewed by me, ok henning@ claudio@
2007-05-06Don't fail hard on non RH0 routing headers. The calculation of the lengthClaudio Jeker
of RH headers is always the same. Now tcpdump just prints the type, length and segleft headers for unknown headers. OK henning@ mcbride@
2007-05-06Fix the out of bounds check when parsing IPv6 headers. Fixes a SIGSEGVClaudio Jeker
when parsing IPv6 headers with unknown or corrupted header options. OK henning@ mcbride@
2007-03-27Fix aligenment issues by using bcopy() and a local variable instead of theClaudio Jeker
problematic *(u_intXX_t*)t casts. This fixes the bus errors I got on sparc64 while doing IEEE802_11_RADIO dumps. OK reyk@ mglocker@
2007-03-26Print the reason code of deauth and disassociation packets if in verbose mode.Claudio Jeker
This helps debugging issues with stations that fail to join a network. OK mglocker@, reyk@, jsg@

2007-01-08c should be u_char for printing option numbers. fix parameter requestKevin Steves

wlan frames (DLT_IEEE802_11 and DLT_IEEE802_11_RADIO linktypes). see tcpdump(8) for details. "Works for me" claudio@ ok jmc@ deraadt@

2006-12-13IPv6 passive OS fingerprinting.Jun-ichiro itojun Hagino
reuses IPv4 signature file (assuming that TCP code is shared among IPv4/v6). mcbride ok.
2006-12-09switch IPv6 advanced API from RFC2292 to RFC3542 (2292 is superseded by 3542).Jun-ichiro itojun Hagino
the kernel still handles RFC2292 set/getsockopts, so that compiled binary has no trouble running. userland sees RFC3542 symbols only on header file so new code has to use RFC3542 API. bump libc shlib minor for function additions. tested on i386/amd64 by jmc, i386 by brad. checked by deraadt.

2006-06-01Pass the captured packet length in addition to the real packet lengthMoritz Jodeit
to etherip_print() and do all the bounds checking with it. Also add bounds checks to ether_print(). This fixes even more crashes. ok canacar@

before accessing it. With some cleanup from canacar@ ok canacar@
2006-05-29The end pointer to fn_print() could possibly point behind the capturedMoritz Jodeit
packet. So make sure, it uses "snapend" in that case. ok canacar@
2006-05-29Add proper bounds checks for the CDP and SSDP protocols byMoritz Jodeit
grouping all LLCSAP_SNAP handling in one block. Also make sure, that enough of "struct llc" was captured, before accessing it. ok canacar@
