2002-08-28Removed trailing whitespaces from .h and .c files using theJörg Mayer1-16/+16
winapi_cleanup tool written by Patrik Stridvall for the wine project. svn path=/trunk/; revision=6115
2002-07-29From Joerg Mayer:Guy Harris1-7/+7
All files: - Replace types from sys/types.h by those from glib.h - Replace ntoh family of macros from netinet/in.h and winsock2.h by g_ntoh family from glib.h - Remove now unneeded includes of sys/types.h, netinet/in.h and winsock2.h wtap.h Move includes to the top svn path=/trunk/; revision=5909
2002-06-07Graeme Hewson noted that zlib has a bug wherein "gzseek()" doesn't setGuy Harris1-10/+4
the internal z_err value for the stream if an "fseek()" call it makes fails, so that if "gzerror()" is subsequently called, it returns Z_OK rather than an error. To work around this, we pass "file_seek()" an "int *err", and have the with-zlib version of "file_seek()" check, if "gzseek()" fails, whether the return value of "file_error()" is 0 and, if so, have it return "errno" instead. svn path=/trunk/; revision=5642
2002-05-22Updated NS_LS_DRIVER to work with both pre-HPUX11 and HPUX11.Ronnie Sahlberg1-20/+49
Added support for NS_LS_TCP, NS_LS_UDP, NS_LS_LOOPBACK, NS_LS_ICMP and unnamed subsystem 0xb9 (which contains ethernet headers in my captures frames). However, NS_LS_ICMP will not be dissected since we dont have a RAW_ICMP wiretap encapsulation type. Updated decoding of usec timestamp for HPUX11 since HPUX11 has 0.1us resolution for the scalar in this field. YMMV but all these ones works for me from nettl traces from HPUX11. svn path=/trunk/; revision=5523
2002-05-17Added support for HPUX11 NETTL captures for the NS_LS_DRIVER type.Ronnie Sahlberg1-1/+108
It works for such captures containing 100baseT captures. It may explode on other link types. svn path=/trunk/; revision=5496
2002-04-09Move the definition of the FROM_DCE bit in the "flags" field of aGuy Harris1-2/+3
"struct x25_phdr" to "wiretap/wtap.h". Have two X.25 dissectors, one of which assumes that there's a "struct x25_phdr" pseudo-header and one of which doesn't; the former uses the information in that pseudo-header to determine whether the packet is DTE->DCE or DCE->DTE, and the latter assumes it has no clue whether the packet is DTE->DCE or DCE->TDE. Use the former one in the LAPB dissector, and the latter one in the XOT dissector and in the LLC dissector table. In the X.25-over-TCP dissector, handle multiple X.25 packets per TCP segment, and handle X.25 packets split across TCP segments. svn path=/trunk/; revision=5134
2002-03-05Make "wtap_seek_read()" return TRUE on success and FALSE on error, likeGuy Harris1-11/+12
"wtap_read()". Add some additional error checks to the Sniffer file reader. svn path=/trunk/; revision=4875
2002-03-05Have "wtap_seek_read()" return 0 on success and -1 on failure, and takeGuy Harris1-8/+16
an "err" argument that points to an "int" into which to put an error code if it fails. Check for errors in one call to it, and note that we should do so in other places. In the "wtap_seek_read()" call in the TCP graphing code, don't overwrite "cfile.pseudo_header", and make the buffer into which we read the data WTAP_MAX_PACKET_SIZE bytes, as it should be. In some of the file readers for text files, check for errors from the "parse the record header" and "parse the hex dump" routines when reading sequentially. In "csids_seek_read()", fix some calls to "file_error()" to check the error on the random stream (that being what we're reading). svn path=/trunk/; revision=4874
2002-03-04Check for errors in seeks, "tell"s, and "stat()"s/"fstat()"s.Guy Harris1-5/+11
For file types where we allocate private data, add "close" routines where they were missing, to free the private data. Also fix up the code to clean up after some errors by freeing private data where that wasn't being done. Get rid of unused arguments to "wtap_dump_open_finish()". Fix indentation. svn path=/trunk/; revision=4857
2002-02-08Have Wiretap set the snapshot length to 0 if it can't be derived fromGuy Harris1-2/+2
reading the capture file. Have callers of "wtap_snapshot_length()" treat a value of 0 as "unknown", and default to WTAP_MAX_PACKET_SIZE (so that, when writing a capture file in a format that *does* store the snapshot length, we can at least put *something* in the file). If we don't know the snapshot length of the current capture file, don't display a value in the summary window. Don't use "cfile.snap" as the snapshot length option when capturing - doing so causes Ethereal to default, when capturing, to the snapshot length of the last capture file that you read in, rather than to the snapshot length of the last capture you did (or the initial default of "no snapshot length"). Redo the "Capture Options" dialog box to group options into sections with frames around them, and add units to the snapshot length, maximum file size, and capture duration options, as per a suggestion by Ulf Lamping. Also add units to the capture count option. Make the snapshot length, capture count, maximum file size, and capture duration options into a combination of a check box and a spin button. If the check box is not checked, the limit in question is inactive (snapshot length of 65535, no max packet count, no max file size, no max capture duration); if it's checked, the spinbox specifies the limit. Default all of the check boxes to "not checked" and all of the spin boxes to small values. Use "gtk_toggle_button_get_active()" rather than directly fetching the state of a check box. svn path=/trunk/; revision=4709

svn path=/trunk/; revision=4199
2001-10-04Use longs as file offsets, so that on platforms with 64-bit "long" weGuy Harris1-5/+5
can handle capture files bigger than 2GB. svn path=/trunk/; revision=3993
2001-03-10Obliging every capture file reader's "open()" routine to seek to theGuy Harris1-2/+1
beginning of the file before reading anything from the file is bogus - do that in the loop that tries each of the open routines, instead. (They may have to reset the seek pointer later if, for example, the capture file begins with the first packet, and the "open()" routine looks at that packet to try to guess whether the packet is in the file format in question.) Set "wth->data_offset" to 0 while you're at it, so capture file readers don't have to do that, either. svn path=/trunk/; revision=3123
2000-11-17Add #include <string.h>, to get prototypes for mem* and str* functions.Gilbert Ramirez1-1/+2
svn path=/trunk/; revision=2654
2000-11-13Support for the BASE100 and GSC100BT subsystems by Jeff Foster.Olivier Abad1-61/+71
svn path=/trunk/; revision=2640
2000-09-07Change wtap_read() API so that the data offset is set via a pointer, andGilbert Ramirez1-8/+7
a "keep reading" boolean value is returned from the function. This avoids having to hack around the fact that some file formats truly do have records that start at offset 0. (i4btrace and csids have no file header. Neither does the pppdump-style file that I'm looking at right now). svn path=/trunk/; revision=2392
2000-08-25Move #include <time.h> into wtap-int.h instead of requiring it inGilbert Ramirez1-2/+1
every C file. I noticed this because of a build break of csids.obj on Win32. svn path=/trunk/; revision=2378
2000-07-26Use unsigned character pointers and arrays rather than signed characterGuy Harris1-5/+5
pointers and arrays in a number of places, to remove warnings some compilers give. svn path=/trunk/; revision=2160
2000-05-19Add wtap-int.h. Move definitions relevant to the internal workins of wiretapGilbert Ramirez1-6/+6
to that file, leave public definitions in wtap.h. Rename "union pseudo_header" to "union wtap_pseudo_header". Make the wtap_pseudo_header pointer available in packet_info struct. svn path=/trunk/; revision=1989
2000-05-19In Wiretap, a file stream handle is a "FILE_T", not a "FILE_T *" (aGuy Harris1-5/+5
"FILE_T" is either a "gzFile" or a "FILE *", depending on whether zlib support is enabled or not). Fix various function declarations and definitions. svn path=/trunk/; revision=1984
2000-05-18Remove the "union pseudo_header" from the "frame_data" structure;Guy Harris1-67/+108
there's no need to keep it around in memory - when the frame data is read in when handing a frame, read in the information, if any, necessary to reconstruct the frame header, and reconstruct it. This saves some memory. This requires that the seek-and-read function be implemented inside Wiretap, and that the Wiretap handle remain open even after we've finished reading the file sequentially. This also points out that we can't really do X.25-over-Ethernet correctly, as we don't know where the direction (DTE->DCE or DCE->DTE) flag is stored; it's not clear how the Ethernet type 0x0805 for X.25 Layer 3 is supposed to be handled in any case. We eliminate X.25-over-Ethernet support (until we find out what we're supposed to do). svn path=/trunk/; revision=1975
2000-04-15Get rid of the "start" field in the private data for RADCOM, i4btrace,Guy Harris1-15/+7
and nettl captures - a "start" field is used for capture files where the time stamps on packets are relative to some initial time stamp, e.g. the time the capture started, but those file formats use absolute time stamps, so no "start" field is needed. Make the "this is an HP-UX 11.x nettl capture" flag a member of the private data structure for a nettl capture, rather than a global - it's per-capture-file state. Once the "start" field is removed from the RADCOM private data structure, there's nothing left, so eliminate the private data structure. svn path=/trunk/; revision=1863
2000-03-22In a Network Monitor capture file, get the starting offsets of framesGuy Harris1-1/+8
from the frame table - Network Monitor 2.x, at least, doesn't always write frame N+1 right after frame N. To do that, we need to mallocate a big array to hold the frame table, and free it when we close the capture file; this requires that we have capture-file-type-specific close routines as well as capture-file-type-specific read routines - we let it the pointer to that routine be null if it's not needed. Given that, we might as well get rid of the switch statement in "wtap_close()", in favor of using capture-file-type-specific close routines, as per the comment before that switch statement. svn path=/trunk/; revision=1740
2000-03-01The frame header in HP-UX 11 trace files is 4 octets longer (than HP-UX 9Olivier Abad1-3/+52
and 10 files). Add OS version detection to handle this. svn path=/trunk/; revision=1675
2000-02-19If we see a file with an unknown network type, report the type in aGuy Harris1-1/+3
"g_message()" message, as other capture-file readers do. svn path=/trunk/; revision=1648
2000-02-17Add support for raw IP nettl captures.Olivier Abad1-47/+116
Update the nettl section in wiretap/README, and give sample commands to make captures on HP-UX. svn path=/trunk/; revision=1642
2000-01-22Fix files that had Gilbert's old e-mail address or that didn't have myGuy Harris1-2/+2
forwarding e-mail address. svn path=/trunk/; revision=1522
2000-01-20The headers of HP-UX 9.04 and HP-UX 10.20 nettl files seem to be different.Olivier Abad1-7/+11
Check for both "magic numbers". svn path=/trunk/; revision=1512
2000-01-13We are obliged to define HAVE_UNISTD_H in "config.h"; to avoid theGuy Harris1-2/+2
hideous problem on FreeBSD 3.[23] (and perhaps other BSDs) if HAVE_UNISTD_H is defined before "zlib.h" is included, turn "file_seek()" into a subroutine defined in a file that *undefines* HAVE_UNISTD_H before including "zlib.h", so that the *only* call to "gzseek()" is made from a file that does not have HAVE_UNISTD_H defined when it includes "zlib.h". Move "file_error()" to that file while you're at it, so it holds all the wrappers that hide the presence or absence of zlib from routines to read capture files. Turn "file.h", which declared those wrapper functions as well as wrapper macros, into "file_wrapper.h" - it belongs with the "file_wrapper.c" file that defines the wrapper functions, not with "file.c" which handles higher-layer file access functions. Remove the comment in "configure.in" that explained why defining HAVE_UNISTD_H was a bad idea, as we're not obliged to define it and work around the problem. (The comment in "file_wrapper.c" explains the workaround.) svn path=/trunk/; revision=1463
1999-10-31Give it an RCS ID.Guy Harris1-9/+8
Fix the error checking ("file_error()" returns an "errno" value *if* there's an error and it's a UNIX error, but it may also return a non-"errno" value for non-UNIX errors, so its return value should be passed back through the "err" pointer). svn path=/trunk/; revision=954
1999-10-18Olivier Abad's patches to add:Guy Harris1-0/+147
more display filters for X.25; no LCN in X.25 RESTART / DIAGNOSTIC / REGISTRATION packets; support for nettl file format (nettl is a trace tool for HP-UX). For now, it only supports traces for X.25 interfaces (tested with HP-UX 10.20). svn path=/trunk/; revision=879
