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.
The purpose of this macro was to enable the file-by-file switch to NDO,
after which only tcpdump.c had a use of it and the definitions guarded
by it. Update tcpdump.c not to require them any more and dismiss the
unused definitions.
And, as we require at least autoconf 2.61, and as autoconf 2.61 and
later have AC_TYPE_UINTn_T and AC_TYPE_INTn_T macros, we use them to
define the uintN_t and intN_t macros if the system doesn't define them
for us.
This lets us get rid of bitypes.h as well.
Have them take a netdissect_options * argument, and get the "no name
resolution" flag from it.
Move the declaration of dnaddr_string to addrtoname.h, along with the
other XXX-to-string routines.
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.
This change adds new code to decode ZeroMQ datagrams, couples it with
the PGM decoder and extends the -T option to make all this work.
There are two new test cases based on existing captures of ZMTP/1.0
inside [E]PGM to decode the ZMTP/1.0 part of these.
This functionality enables decoding of the traffic zeromq library
produces for "pgm://" and "epgm://" protocol schemas.
1. "TSDU Length" comes in network byte order on wire, add missing macro.
2. The (unused) justification of the number of bytes on wire wasn't
correct because one side of the comparison included header size and
another didn't (note the byte order as well). Besides that, the value of
TSDU Length was already output thus far. Don't justify the number of
bytes on wire and change the final printf() to make a use of it.
being extracted as its argument.
For PGM messages, always advance "bp" to point to the beginning of the
options.
The length of OPT_FRAGMENT is 16, not 12.
Show the option type without the "end of options" bit.
Fix the message type in "Bad XXX option" messages.
The first option must be an OPT_LENGTH option; make sure it is, and use
that length when processing the option list, rather than just running to
the end of the packet or an OPT_END, whichever comes first.
