| 2014-12-03 | Restore packetp and snapend pointers once we're done with an incorrectly | Mike Belopuhov | |
| aligned IP/IPv6 packet so that tcpdump can print hexdump of the whole packet including the Ethernet header (if requested) and not only the IP/IPv6 part of it. ok jsg | |||
| 2014-12-03 | Fixup a crash found by jsg using the AFL fuzzer. IP and IPv6 printing | Mike Belopuhov | |
| routines should check that there's at least a complete IP/IPv6 header available in the buffer before trying to do anything else. ok jsg | |||
| 2014-11-26 | Prefer setvbuf() to setlinebuf() for portability; ok deraadt@ | Todd C. Miller | |
| 2014-11-20 | better length handling. Fixes a crash found with the afl fuzzer. | Jonathan Gray | |
| slightly tweaked version of an earlier diff ok'd by djm@ and miod@ | |||
| 2014-11-20 | sanity check the length of the packet in the pcap header | Jonathan Gray | |
| fixes a crash found by the afl fuzzer ok djm@ miod@ | |||
| 2014-11-20 | Make ip6_print() take an unsigned length matching | Jonathan Gray | |
| ip_print() and others. Allows code deciding on a minimum length to memmove() to work as intended, preventing various crashes found with the afl fuzzer. Callers of ip6_print() should of course be fixed to provide sane lengths as well. ok deraadt@ djm@ | |||
| 2014-10-08 | obvious malloc() -> reallocarray() oflow check; ok doug | Theo de Raadt | |
| 2014-08-14 | No use for <netinet/in_systm.h> nor <netinet/tcpip.h>. | Martin Pieuchot | |
| 2014-07-20 | Fix tcpdump(8) display of logical link control data in IEEE802 frames. | Stefan Sperling | |
| The frame subtype field is in the first byte of frame control but tcpdump(8) was looking at the second byte to determine if this is a data frame. Patch by Nathanael Rensen, thanks! | |||
| 2014-07-04 | Tcpdump did not show the OSPF router id of hello packets if it was | Alexander Bluhm | |
| equal to the source ip address. This is confusing and inconsistent with IPv6. So always print the rtrid. OK stsp@ | |||
| 2014-06-30 | remove backwards compat layer for alpha osf1. back then compilers and | Theo de Raadt | |
| the parsers sucked, so byte misalignment repair was requested. These days it means the parsers should improve. ok lteo | |||
| 2014-06-20 | Instead of showing the difference between a bad checksum and a good | Lawrence Teo | |
| checksum, make tcpdump (with the -v flag) show the actual bad checksum within the IP/protocol header itself and what the good checksum should be, e.g. "[bad tcp cksum abcd! -> d1e6]" This change applies to IP, TCP (over IPv4 and IPv6), UDP (over IPv4 and IPv6), ICMP, and ICMPv6. This commit also fixes several inconsistencies in the way bad checksums were displayed for these protocols. Tested on amd64, i386, and macppc. ok henning@ | |||
| 2014-06-20 | Import in_cksum_shouldbe() from mainline tcpdump; this is needed by my | Lawrence Teo | |
| upcoming commit which will fix and improve the display of bad checksums for the major protocols. ok henning@ | |||
| 2014-06-03 | Expand the IP checksum offload subsection to mention the same issue with | Lawrence Teo | |
| protocol checksum offload, where tcpdump might see bad checksums on valid packets. ok henning@ jmc@ | |||
| 2014-05-23 | Don't print a "weird flag" type warning "[b2&3=0x2400]" for DNS NOTIFY | Stuart Henderson | |
| messages which should be sent with AA set. Adapted from a patch at http://marc.info/?l=tcpdump-patches&m=98115734907026&w=2 pointed out by Peter J. Philipp, ok henning@ | |||
| 2014-02-19 | Add pcap-filter(3) to the SEE ALSO section. | Lawrence Teo | |
| ok jmc@ | |||
| 2014-02-05 | Don't segfault on IPv6 NFS traffic; found the hard why by matthieu@. | Florian Obser | |
| Fix inspired by what upstream is doing. Tested by me and matthieu@. Input^WHand holding and OK guenther@ | |||

| 2014-01-11 | Let tcpdump detect bad ICMPv6 checksums with the -v flag. | Lawrence Teo | |
| Tested on amd64, i386, loongson, and macppc. OK florian@ | |||
| 2014-01-11 | Let tcpdump detect bad ICMP checksums with the -v flag. | Lawrence Teo | |
| Tested on amd64, i386, loongson, and macppc. OK florian@ | |||
| 2014-01-11 | Make icmp_print() accept the length variable, which is the length of the | Lawrence Teo | |
| packet without the IP header. This is needed by the next commit that will allow tcpdump to detect bad ICMP checksums. Related functions like {tcp,udp,icmp6}_print() already accept this length variable, so this change makes icmp_print() consistent with them as well. This commit makes no functional change to tcpdump itself. OK florian@ | |||
| 2013-12-22 | ctype cleanups, now that the kernel has u_char strings (that is the | Theo de Raadt | |
| easy road, otherwise this would be a righteous mess) ok florian | |||
| 2013-12-03 | no need for timeb.h | Theo de Raadt | |
| 2013-10-27 | If a constant string needs a name, use a static const array instead of a | Philip Guenther | |
| pointer or non-const array, as that minimizes the symbols, maximizes the placement into read-only memory, and avoids warnings from gcc -Wformat=2 when they're used as format strings. ok deraadt@ | |||
| 2013-10-24 | These two programs got fooled by the KAME/NRL split and need type repair. | Theo de Raadt | |
| They do not indicate a problem with the reduction of namespace export, but got suckered into the 1999 plan. ok benno | |||

| 2013-07-10 | In the EXAMPLES section, it is not very obvious that "localnet" is not a | Lawrence Teo | |
| literal argument name due to lack of formatting, so replace it with an example network to make it clearer (discussed with and suggested by jmc@). While here, fix some style nits in a sentence to make it consistent with the other examples. ok jmc | |||
| 2013-06-19 | Do not install pcap-int.h to /usr/include as it is an internal library | Lawrence Teo | |
| header (pointed out by matthew@). Let only pflogd and tcpdump include pcap-int.h directly since they need it for privilege separation. "looks good" sthen feedback/ok deraadt matthew millert | |||

| 2013-01-17 | Dump some more flags and subtypes in tcpdump. Especially flags used in | Claudio Jeker | |
| power saving mode. OK giovanni@ | |||
| 2012-11-14 | In the unlikely event that a NULL device is passed to priv_pcap_live(), | Lawrence Teo | |
| ensure that the function will stop and return NULL instead of continuing (which could lead to a segfault). ok benno deraadt otto | |||

| 2012-08-24 | We maintain our own tcpdump, so remove the sentence in the BUGS section | Lawrence Teo | |
| that asks users to send bug reports to mainline tcpdump. While here, fix two mandoc -Tlint warnings by removing unnecessary .Pp instances. ok deraadt jmc naddy | |||

| 2012-07-08 | New attempt to make the -P flag work with -ss, so that states can be | Lawrence Teo | |
| printed with port names if desired. tcpdump's pf_print_state.c has diverged significantly from pfctl's, so the change to tcpdump's pf_print_state.c is not exactly the same as pfctl's. ok henning sthen | |||
