2003-06-12Add new routines:Guy Harris1-15/+5
tvb_get_string() - takes a tvbuff, an offset, and a length as arguments, allocates a buffer big enough to hold a string with the specified number of bytes plus an added null terminator (i.e., length+1), copies the specified number of bytes from the tvbuff, at the specified offset, to that buffer and puts in a null terminator, and returns a pointer to that buffer (or throws an exception before allocating the buffer if that many bytes aren't available in the tvbuff); tvb_get_stringz() - takes a tvbuff, an offset, and a pointer to a "gint" as arguments, gets the size of the null-terminated string starting at the specified offset in the tvbuff (throwing an exception if the null terminator isn't found), allocates a buffer big enough to hold that string, copies the string to that buffer, and returns a pointer to that buffer and stores the length of the string (including the terminating null) in the variable pointed to by the "gint" pointer. Replace many pieces of code allocating a buffer and copying a string with calls to "tvb_get_string()" (for one thing, "tvb_get_string()" doesn't require you to remember that the argument to "tvb_get_nstringz0()" is the size of the buffer into which you're copying the string, which might be the length of the string to be copied *plus 1*). Don't use fixed-length buffers for null-terminated strings (even if the code that generates those packets has a #define to limit the length of the string). Use "tvb_get_stringz()", instead. In some cases where a value is fetched but is only used to pass an argument to a "proto_tree_add_XXX" routine, use "proto_tree_add_item()" instead. svn path=/trunk/; revision=7859
2003-05-09Move the ntlmv2 response dissection out of packet-ntlmssp.c and in toTim Potter1-1/+199
packet-smb-common.c so it can be used elsewhere. Dissect a ntlmv2 response in a session setup SMB if detected. svn path=/trunk/; revision=7655
2003-04-03Add an extra argument to get_unicode_string() to optionallyTim Potter1-3/+6
pass back string data. Start adding some COL_INFO tidbits for NETLOGON PDC query and PDC query response. svn path=/trunk/; revision=7399
2003-04-03Add an extra argument to get_ms_string() so we can optionally passTim Potter1-9/+8
back the value of the string to the caller. svn path=/trunk/; revision=7398
2002-08-28Removed trailing whitespaces from .h and .c files using theJörg Mayer1-12/+12
winapi_cleanup tool written by Patrik Stridvall for the wine project. svn path=/trunk/; revision=6117
2002-08-10From Devin Heitmueller: dissect NTLMSSP authentication messages, and handleGuy Harris1-1/+146
the flags field in NTLMSSP messages as a 32-bit field. Make "get_unicode_or_ascii_string()" take a "Unicode or not" flag rather than a "packet_info *" as an argument, make it not static, and move it to "packet-smb-common.c", so that it can be used by the SMB dissector and the NTLMSSP dissector. Also get rid of some _U_'s that are applied to arguments that are, in fact, used. svn path=/trunk/; revision=5976
2002-06-16Fix "display_unicode_string()" to get the length of the Unicode string,Guy Harris1-17/+46
allocate a buffer big enough to hold the ASCIIfied version of that string, and then ASCIIfy the Unicode string into that buffer, rather than ASCIIfying into a fixed-length buffer. svn path=/trunk/; revision=5676
2002-05-27Account for hidden share types in share_types.Richard Sharpe1-1/+5
svn path=/trunk/; revision=5572
2002-05-24Move the value_string table for the share type values toGuy Harris1-1/+12
"packet-smb-common.c", and use it in "packet-dcerpc-srvsvc". svn path=/trunk/; revision=5545
2002-04-30Get rid of some unused arguments, and mark some others as unused.Guy Harris1-4/+4
Remove the declaration of "dissect_nt_sid()" from "packet-dcerpc-samr.c"; get it by including "packet-smb-common.h", instead. svn path=/trunk/; revision=5313
2002-01-24Replace a bunch of "tvb_length()" and "tvb_length_remaining()" calls inGuy Harris1-7/+4
arguments to "proto_tree_add_text()", and to "proto_tree_add_XXX()" calls that add FT_NONE or FT_PROTO items to the protocol tree, with -1. Replace some calls to "tvb_length()" or "tvb_length_remaining()" with calls to "tvb_reported_length()" and "tvb_reported_length_remaining()", as those give the actual length of the data in the packet, not just the data that happened to be captured. svn path=/trunk/; revision=4605
2001-07-08Get rid of incorrect "const" qualifier.Guy Harris1-2/+2
svn path=/trunk/; revision=3664
2001-07-08Use tvbuff-based routines to find the length of single-bit-character-setGuy Harris1-5/+20
strings. svn path=/trunk/; revision=3662
2001-07-08Tvbuffified SMB NETLOGON dissector, from Ronnie Sahlberg.Guy Harris1-101/+29
Fixed up some longstanding bugs (predating the tvbuffification) discovered during regression testing of the tvbuffification. svn path=/trunk/; revision=3661
2000-05-11Add tvbuff class.Gilbert Ramirez1-6/+6
Add exceptions routines. Convert proto_tree_add_*() routines to require tvbuff_t* argument. Convert all dissectors to pass NULL argument ("NullTVB" macro == NULL) as the tvbuff_t* argument to proto_tree_add_*() routines. dissect_packet() creates a tvbuff_t, wraps the next dissect call in a TRY block, will print "Short Frame" on the proto_tree if a BoundsError exception is caught. The FDDI dissector is converted to use tvbuff's. svn path=/trunk/; revision=1939
2000-02-14In "display_flags()", panic if the size handed to it is neither 1, 2,Guy Harris1-5/+19
nor 4, as we currently don't handle that. svn path=/trunk/; revision=1634
2000-02-14Fix the comment at the beginning of the file.Guy Harris1-3/+2
svn path=/trunk/; revision=1630
2000-02-14Jeff Foster's SMB Mailslot and Netlogin dissectors; he splitGuy Harris1-0/+142
"packet-smb.c" up into several files. svn path=/trunk/; revision=1629
