Running out of packet length before running out of unreachable
destinations is an error; report it as such.
Don't worry about leftover data past the end of the list of unreachable
destinations.
Use ND_TCHECK() rather than home-brew bounds checks. Do simpler length
checks.
Let i be the length of the actual remaining packet data; use ND_TCHECK()
inside loops that iterate over the remaining data.
Let the printers for particular message types cast the raw data pointer
to a pointer of the appropriate type, rather than passing two pointers,
with different types, to the same data.
Have "struct aodv_rerr" just be the header, not including the actual
destinations.
Simplify the logic somewhat, and make it similar in the print routines
for the three types of error messages.
Fetch the type field without using a structure, and check to make sure
it's not past the end of the packet.
Pass to each dissection routine a pointer to the appropriate message
type structure, rather than a pointer to a union of all the message type
structures.
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.
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.
appropriately, and that GNUmakefile and the MSVC++ project file define
it apppriately, as we do with libpcap, rather than defining it in
"interface.h".
Undo the rcsid-shuffling and addition of extra #includes, as we no
longer need to arrange that "interface.h" be included before using _U_
in an RCS ID or copyright.
use "_U_" in the definitions of "rcsid[]", to eliminate
complaints about those variables being unused;
move the definitions after the include of "interface.h", or add
an include of "interface.h", so that "_U_" is defined.
Include "config.h" before including "tcpdump-stdinc.h" in
"missing/datalinks.c".
Fix numerous bugs in my AODV submission, red faces all round,
mainly due to misunderstanding of EXTRACT_STRING() macro
arguments (because these are macros, type checking didn't
happen).
AODV HELLO extensions are now correctly printed.
The code is closer to FreeBSD's style guidelines.
Don't use "u_char" and "u_long", use "u_int8_t" and "u_int32_t".
"u_long" is definitely wrong as it's 64 bits on some platforms; "u_char"
is safe, but the official tcpdump style uses "u_int8_t".
At least according to the (long-since-expired) draft-perkins-aodv6-01,
the V6 AODV messages have different message type values from the V4 ones
in draft-ietf-manet-aodv-13. However, draft-ietf-manet-aodv-13 says
that the only differences are in the addresses; we support both.
Clean up the way we tell the AODV6 dissector that we're running atop
IPv6 a bit.
Use "udpipaddr_print()" if we're printing AODV packets as a result of
saying "anything that matches this filter is AODV", rather than doing it
ourselves under the assumption that it's running over IPv4.
