2013-03-29Rename value string (and similar) functions to use a consistent pattern. ThisEvan Huus1-1/+1
was done using textual search+replace, not anything syntax-aware, so presumably it got most comments as well (except where there were typos). Use a consistent coding style, and make proper use of the WS_DLL_* defines. Group the functions appropriately in the header. I ended up getting rid of most of the explanatory comments since many of them duplicated what was in the value_string.c file (and were out of sync with the recent updates I made to those in r48633). Presumably most of the comments should be in the .h file not the .c file, but there's enough churn ahead that it's not worth fixing yet.

reject packets that don't look enough like GTP/GTP' packets. This fixes bug 1706, and fixes some other cases where non-GTP/GTP' packets are being dissected as GTP/GTP'. svn path=/trunk/; revision=48118
2013-03-05Use hf_gtp_ext_hdr_next for all "next header" fields, and get rid ofGuy Harris1-20/+3
hf_gtp_next. Don't do "dummy" dissection of extension headers that we don't actually dissect - we label them by next extension header type, and dissect them in the default case, which should suffice (until somebody adds dissection for those types). svn path=/trunk/; revision=48075
2013-03-04If the length value is bad, an exception will be thrown; we don't needGuy Harris1-2/+2
the item for the length, as we aren't explicitly checking it and attaching expert info items to it. svn path=/trunk/; revision=48070
2013-03-04Give 3GPP TS numbers for GTP v0, GTP v1, and GTP'.Guy Harris1-234/+218
Give URLs for the 3gpp.org pages for all those specs. Add #defines for all the GTP v1 extension header types we handle. "gtp_prime" is a Boolean; make it a gboolean. Dissect the first 4 octets of the header one field at a time, so that if the packet is cut short by a snapshot length we at least dissect what's there. 32.295 isn't entirely clear on what the 20-byte header for GTP' v0 is; assume it's the same as the header for GTP v0. Once we've fetched the length field from the fixed-length portion of the header, set the length of the tvbuff to the sum of the offset past the fixed-length portion and the length field, to catch running past that value. Use GTP_E_MASK|GTP_S_MASK|GTP_PN_MASK as the mask for testing for the presence of those fields, to make it a bit clearer what's being checked for. Don't actually add those fields to the protocol tree unless the flag for the field is set. We only need one chunk of code to handle extension headers. Make that chunk a loop, and put the header in as an FT_NONE item, with the length, header data, and next header under it. Put the initial next header field in as well. (We treat this like IPv6 extension headers, with the next header field being part of the previous header, rather than like a set of TLVs, with the next header field being the type value of its header.) Fail if the extension header length is zero. Use the reported length when processing IEs or T-PDU payload. svn path=/trunk/; revision=48068

2012-03-30From Liangfeng via https://bugs.wireshark.org/bugzilla/show_bug.cgi?id=7012 :Jeff Morriss1-4/+4
According to 3GPP R7//R8/R9/R10/R11, AVP 'MBMS-Session-Duration' has 3 octets. First 17 bits indicate seconds, the rest of bits(7 bits) represents days. However, in the source file packet-gtp.c, it parse the AVP reversely -- taking first 7 bits as days, the rest of 17 bits as seconds. This patch fixes that. svn path=/trunk/; revision=41849
