b756fcfd81 bugfix: the IS-IS Multi-topology TLV MTID is prepended once per TLV and not once per MT-IS neighbor 2008-08-16 13:38:15 +00:00

6fb52fa951 Add HMAC-MD5 verification support for IS-IS 2008-08-16 12:07:17 +00:00

b0757875e2 bugfix: the Multi-topology header is just at the beginning of the TLV and not before every prefix 2007-03-02 09:16:19 +00:00

600222a669 from Jacek Tobiasz <Jacek.Tobiasz@atm.com.pl>: 
display the IS-IS istype field as L2 and not L1L2.

de5421422e do not bail if we hit a zero-length TLV, continue to read the next TLV header instead. 2006-06-16 18:08:35 +00:00

df7c862246 From Don Ebright: fix a place where we were referring to AF_INET6 even 
when INET6 wasn't defined.

085929abcb Get rid of an #ifdef - to zero something out with memset, just use 
"sizeof something" as the size argument.

02c692dc72 From Markus Schoepflin: don't use "struct in6_addr" if INET6 isn't 
defined, because, in that case, "struct in6_addr" probably isn't
defined, either.

Check for too-large bit lengths in TLVs.

4dc9cccc3e retain the old diffserv-te codepoints for a transition period 2005-09-20 10:04:26 +00:00
guy
1c47cfa81a But the PDU length checks back, so "tmp" doesn't go negative. 
At least as I read RFC 3847, you won't get a system ID without the
remaining hold time field; after printing the flags field, check whether
there's anything else after the flag field and, if not, quit, otherwise
print the remaining hold time field and, if present, the system ID field.

806a7cab5c rework the restart signaling TLV printer: 
-accept TLV length of 1 as this is now perfectly valid as per rfc 3847
  -only attempt to print a trailing system-ID and not a node-ID

f6e4e639b3 code cosmetics: add a few TLV_MINLEN #defines 2005-07-14 20:10:03 +00:00
hannes
67eb31b994 code cosmetics: 
at places where the entity to print / or increment
  shares the semantics of an IPv4 or IPv6 address
  use sizeof(in_addr) and sizeof(in6_addr),
  rather than a hardcoded 4 or 16

531ae3fff9 We've already subtracted the fixed 36 bytes from subl, no need to do it 
again.

b6b9e87a04 typo: the codepoint for complete source routing in the sr clnp option is 0x1 and not 0x0 2005-06-08 06:40:10 +00:00

2b08b7635e And add checks of the NSAP offset. 2005-05-25 22:06:24 +00:00

c0fd6776c1 Don't print ", " before the length if we're printing the link-layer 
header, as the ", " isn't necessary, and looks ugly, in that case.

Use TCHECK() and TCHECK2() for bounds checking, and do more bounds
checking.

3ac9165c1f bugfix: do not attempt to decode zero-length TLVs, only attempt to decode IS-REACH (varlength) TLVs if the TLV length indicates that there is at least a single byte on the wire 2005-04-25 09:09:11 +00:00
guy
ee44728e80 Don't exit just because an NSAP had a length of 0 or a too-long length; 
just report it as an illegal length.

Check for some zero-length or too-short TLVs not already checked for.

4189fb7df6 refactored ip_print() so that chained header parser (ESP/AH) can

810773f6e9 - bugfix: start CLNP checksumming at the packet start 
- display the reqesting packet header of the Echo response payload

cddcb5632d code cleanup: 
- remove the private print_nsap() and use isonsap_string() instead
  - pass on a length indicator to isonsap_string as CLNP and ES-IS,IS-IS TLVs
    and options store the length differently (semioctets vs. octets)
  - make the isonsap_string() output equal to the now abandoned print_nsap()
    printer which reflects representation of contemporary router software

  that we are crossing a layer boundary

7e54d6cb05 -extend the OSI NLPID dissector for printing IP and IP6 packets 
- do some display (comma) cosmetics (output will remain the same);

   one day we need to move the nlpid dissector from print-isoclns
   to (new) print-nlpid.c
 2004-10-18 12:34:36 +00:00
