Add missing GET_U_1() wrappers to cover struct igrprte properly again,
also deduplicate some code.
This fixes a buffer over-read introduced in a recent commit 09b9aad and
discovered by Hardik Shah.
Add a test using the capture file supplied by the reporter.
Simplify igrp_entry_print(). In igrp_print() always fetch the checksum
to make all ND_TCHECK_LEN() instances redundant and remove them. Test
that the full declared length has been consumed at the end. Report
invalid packets as invalid, not truncated. Update a comment.
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
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.
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.
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.
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".
Finish converting over to having the caller print the IP address
(except for UDP, TCP and SCTP). This consists mostly of removing
places where the IP address is printed, both in the big "case"
in ip_print() and in the individual printers.
Also fix a couple of spacing bugs.
have dissectors include them rather than <netinet/ip.h> or
<netinet/ip_var.h>, if they actually need that stuff.
Put the declarations of the ICMP stuff directly into "print-icmp.c".
Remove all unnecessary includes of <netinet/ip*.h> files.
Copy the byte-order stuff from "nameser.h" into "tcp.h".
by dissectors, and have dissectors include them rather than
<netinet/udp.h>, <netinet/udp_var.h>, or <netinet/tcp.h>, if they
actually need that stuff.
Remove all unnecessary includes of <netinet/udp*.h> or <netinet/tcp*.h>
files.
Hope I did not break anything. Portability on IPv4-only node needs checking,
I'll do this very soon. (sorry for rather jumbo commit)
XXx what is _FAVOR_BSD?
