Use the two-argument version of AC_INIT() - which requires autoconf 2.64
or later, so require that as a minimum - and get the version string from
the VERSION file. Use AC_CONFIG_SRCDIR() to say that the source
directory needs tcpdump.c; the two-argument version of AC_INIT() doesn't
do that.
This means that we no longer have a version.c file.
Some time between the mid 1980's and 1990 called; they want their
old-fashioned UNIX signal handling back. ANSI C has had signal handlers
returning void sincer, well, 1989, and POSIX has had sigaction() since
close to forever. No need to worry about really old UN*Xes here.
On Windows, it's also void (as per ANSI C); use signal().
Yes, the behavior of an access with an improperly-aligned pointer is
undefined according to the C standard, but if we're doing that in an
EXTRACT_ function/macro, we're doing it because we know it's safe and
because it's faster than picking the bytes out one by one and assembling
them, so suppress those warnings.
Pull over libpcap's funcattrs.h and use it to do a bunch of checks for
various function attributes; that defines __has_attribute(), so we can
use it to check for the "suppress sanitizer warnings" attribute.
While we're at it, use other things it defines to specify "this function
never returns", "this function is printf-like", and "this function
argument is a printf-style format argument", rather than using various
configure-script checks. That should let us declare some function
attributes with Microsoft Visual Studio's compilers.
The target name is 'extags'.
Exuberant Ctags has no -d, -t options and -w is ignored.
Moreover:
Remove a non-existent file in TAGHDR to avoid an error on Debian:
make: *** No rule to make target '/usr/include/net/slip.h',
needed by 'extags'.
Move stuff to initialize and clean up libraries that are used by
netdissect code into nd_init() and nd_cleanup() routines in
libnetdissect; this includes Winsock (which is used on Windows by, for
example, the code to get names for IP addresses) and libsmi.
Call nd_init() when tcpdump starts up, and call nd_cleanup() when it
exits.
Move util.c routines to tcpdump.c, and make them static.
Use ndo->ndo_error to report a failure to open a file in print-esp.c.
This commit adds support for RESP as defined in: http://redis.io/topics/protocol.
It also supports inline commands and pipelining. Due to the popularity of RESP,
numerous services are emerging that use this protocol. You may decode RESP packets
on arbitrary ports using the "-T resp" option.
Example captures can be found in tests/resp_*.
A simple way to test this parser is to start redis-server and then run
redis-cli commands such as "redis-cli set key value".
Traditionally, redis-cli monitor is used to debug redis. Unfortunately,
the "monitor" command can cause significant load on a redis-server in
production. This parser may be used as a non-invasive alternative to
redis-cli monitor.

Printing useful info incase not built with IPv6 support
Have our own routines to convert between IPv4/IPv6 addresses and
strings; that helps if, for example, we want to build binary versions of
tcpdump for Windows that can run both on NT 5 (W2K/WXP), which doesn't
have inet_ntop() or inet_pton(), and NT 6 (Vista/7/8/10), which do. It
also means that we don't require IPv6 library support on UN*X to print
addresses (if somebody wants to build tcpdump for older UN*Xes lacking
IPv6 support in the system library or in add-on libraries).
Get rid of files in the missing directory that we don't need, and
various no-longer-necessary autoconf tests.
- Fix display of some nanoseconds timestamps
For example, bad print 00:-16:-2.000851566 is now 00:00:00.037851566
- Fix display of timestamp of a packet when it is lower than previous one
For example, bad print 00:00:-1.000999790 is now -00:00:00.000000210
Do the case-insensitive comparisons in a locale-independent fashion that
only maps ASCII letters, in the standard English-language fashion; that
way, we don't get bitten by, for example, Turkish having separate "i
with dot" and "i without dot" letters, with lower-case "i with dot" being
mapped to upper-case "I with dot" rather than being mapped to "I".
This header can be used with Marvell switches to direct packets in/out
of a specific port in a tree of interconnected switches. The header
uses its own Ethertype of 0xdada.
By default, only brief output is printed, showing the switch device,
port, and vlan the packet is to/from. However if -e is given, to print
the link-level header, all fields are printed.
"Text protocols" are protocols that have the general feel of FTP, with
command lines with a command name and space-separated arguments and
response lines beginning with a 3-digit reply code. They can also
include HTTP-style headers and an entity body.
We add support for the FTP control channel, HTTP, SMTP, and RTSP. We
also change the SIP printer to use it.
Always define and declare ip6_print(), always compile print-ip6.c, and
always call it if we recognize a payload as IPv6. If INET6 isn't
defined, ip6_print() will just print the length and note that printing
isn't supported.
That way, we don't do weird dissection of IPv6 packets on systems
without IPv6 support, due to, for example, ethertype_print() returning 0
("not dissected") for IPv6 packets on those systems (IPv6-over-Frame
Relay was dissected weirdly due to this).
The sample capture was produced with two Linux hosts (aoetools version
36, kernel module version 85, vblade version 21). One of the hosts
exported a 1MB block device containing a freshly created filesystem and
the other mounted it, wrote a small file and then unmounted.
This requires us to check for it in the configure script and to include
a version of getopt_long() for the benefit of platforms that don't have
it; we pick up the FreeBSD version and tweak it a bit (eliminating some
features specific to the BSD version of getopt_long(), as we want to use
it only in a fashion portable to Linux/*BSD/Solaris/etc.)
We also get rid of the version of getopt() we supply for Windows in
favor of the version of getopt_long() we provide.
SCTP's payload protocol identifiers added.
M3UA tests provided by wireshark
http://wiki.wireshark.org/SampleCaptures#Sigtran_Protocol_Family
But RFC4666 tells that parameter 0x0002 aren't carried by M3UA, so
it's OK that tcpdump doesn't know about this identifier.
Conflicts:
Makefile.in
interface.h
print-sctp.c
sctpConstants.h
-----------------------------------------------------------------------
The change to sctp_print() does three things:
* makes detection of ForCES consider PPID, not just port number
* verifies chunk length of all SCTP_DATA chunks, not just of ForCES
* adds PPID-specific dispatching with a particular case of M3UA
-- Denis
tcpdump used to print an empty line for a Loopback (CTP) packet, which
many Cisco switches send by default every 10 seconds. This commit adds
a decoder for the protocol and a test case, which uses the sample
capture from Wireshark wiki (configuration_test_protocol_aka_loop.pcap).
Remove lots of $Header's and a few $Id's that all belong to the former
CVS repository of tcpdump itself. These keywords have been frozen since
the migration to git in late 2008.
