The exceptions are currently:
Some EXTRACT_ in print-juniper.c, not used on packet buffer pointer.
An EXTRACT_BE_U_3 in addrtoname.c, not always used on packet buffer
pointer.
This can prevent bizarre failures if, for example, you've done a
configuration in the top-level source directory, leaving behind one
config.h file, and then do an out-of-tree build in another directory,
with different configuration options. This way, we always pick up the
same config.h, in the build directory.
Now all the macros have a name meaning a count in bytes.
With _S_: signed, _U_: unsigned
e.g.:
EXTRACT_BE_32BITS -> EXTRACT_BE_U_4
EXTRACT_LE_32BITS -> EXTRACT_LE_U_4
...
EXTRACT_BE_INT32 -> EXTRACT_BE_S_4
and have:
EXTRACT_8BITS -> EXTRACT_U_1
EXTRACT_INT8 -> EXTRACT_S_1
with the tag '\summary:' for greping.
Remark: Currently some printers have no summary line.
Moreover:
Summarize all printers with a single line in INSTALL.txt
Step through the SCTP packet with the bp variable, and keep a packet
data remaining variable and use that for bounds checking. For each
chunk, keep a chunk data remaining variable and use that as well. If
there's not enough room for a full item, that gets reported as an error.
While we're at it, fix an error printout.
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.
Merge m3ua.h into the only file that includes it (print-m3ua.c). Make
M3UA functions follow naming pattern, constify some of their arguments
and switch to ND_PRINT(). Make use of tok2str() and ternary conditional.
Eliminate declarations in the middle of code (C89).
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:

print-sctp.c

-----------------------------------------------------------------------
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

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.
For headers included in only one source file, put the header contents in
the source file in question, and get rid of a bunch of stuff from the
header not used in the source file.
Make sure all of them are declared const and most of them -- static.
Proper declaration of token arrays is a common review point for new code
that is based on existing decoders. Thus fix the issue at its root.
The old ports for SCTP TML ports were replaced at RFC editor
publication time. Caught by folks preparing for an Interop
tommorow.
While we could add a backward compat support it seems meaningless
if those ports will never ever be used in production.
I will send new test/pcaps at a later point and remove the existing
ones once this patch goes in.

There's no guarantee that those quantities will be properly aligned, nor
is there any guarantee that fetching an improperly-aligned quantity will
work as desired.
link-layer print routines if no other print routine claimed the packet.
Test whether that flag is set rather than testing whether neither of -x
or -q were specified, and have -x, -q, *and* -X set that flag, so that
-X suppresses it just as -x does. That way you don't get those pckets
dumped twice if -X was specified.
fact, don't even use "u_int32_t", as we're just pointing into a packet,
which is made up of bytes - use "u_char", and bump the pointer by 4 for
each item.
