Check in Olivier Abad's patch to add dissectors for LAP-B and X.25, and
wiretap support for RADCOM Ltd.'s WAN/LAN analyzers (see
http://www.radcom-inc.com/
). Note: as I remember, IEEE 802.2/ISO 8022 LLC has somewhat of an SDLC
flavor to it, just as I think LAP, LAPB, LAPD, and so on do, so we may
be able to combine some of the LLC dissection and the LAPB dissection
into common code that could, conceivably be used for other SDLC-flavored
protocols.
Make "S" a mnemonic for "Summary" in the "Tools" menu.
Move the routine, used for the "Tools/Summary" display, that turns a
wiretap file type into a descriptive string for it into the wiretap
library itself, expand on some of its descriptions, and add an entry for
files from a RADCOM analyzer.
Have "Tools/Summary" display the snapshot length for the capture.

Have the per-capture-file-type open routines "wtap_open_offline()" calls
return 1 on success, -1 if they got an error, and 0 if the file isn't of
the type that file is checking for, and supply an error code if they
return -1; have "wtap_open_offline()" use that error code. Also, have
the per-capture-file-type open routines treat errors accessing the file
as errors, and return -1, rather than just returning 0 so that we try
another file type.
Have the per-capture-file-type read routines "wtap_loop()" calls return
-1 and supply an error code on error (and not, as they did in some
cases, call "g_error()" and abort), and have "wtap_loop()", if the read
routine returned an error, return FALSE (and pass an error-code-pointer
argument onto the read routines, so they fill it in), and return TRUE on
success.
Add some new error codes for them to return.
Now that "wtap_loop()" can return a success/failure indication and an
error code, in "read_cap_file()" put up a message box if we get an error
reading the file, and return the error code.
Handle the additional errors we can get when opening a capture file.
If the attempt to open a capture file succeeds, but the attempt to read
it fails, don't treat that as a complete failure - we may have managed
to read some of the capture file, and we should display what we managed
to read.

Have the Wiretap open, read, and seek-and-read routines return, in
addition to an error code, an error info string, for
WTAP_ERR_UNSUPPORTED, WTAP_ERR_UNSUPPORTED_ENCAP, and
WTAP_ERR_BAD_RECORD errors. Replace the error messages logged with
"g_message()" for those errors with g_strdup()ed or g_strdup_printf()ed
strings returned as the error info string, and change the callers of
those routines to, for those errors, put the info string into the
printed message or alert box for the error.
Add messages for cases where those errors were returned without printing
an additional message.
Nobody uses the error code from "cf_read()" - "cf_read()" puts up the
alert box itself for failures; get rid of the error code, so it just
returns a success/failure indication.
Rename "file_read_error_message()" to "cf_read_error_message()", as it
handles read errors from Wiretap, and have it take an error info string
as an argument. (That handles a lot of the work of putting the info
string into the error message.)
Make some variables in "ascend-grammar.y" static.
Check the return value of "erf_read_header()" in "erf_seek_read()".
Get rid of an unused #define in "i4btrace.c".

When capturing, report errors trying to create the output file
with "file_open_error_message()".
Make the "for_writing" argument to "file_open_error_message()" a
"gboolean", as it's either TRUE (if the file is being opened for
writing) or FALSE (if it's being opened for reading).
Report EISDIR as "XXX is a directory (folder), not a file.".
When checking whether an "open()" of a capture file succeeded, check
whether "open()" returns a negative number, not whether it returns 0.
In "wtap_open_offline()", if the file to be opened is a directory,
return EISDIR, not WTAP_ERR_NOT_REGULAR_FILE, so that the error message
can say "that's a directory, not a file".
If "wtap_open_offline()" returns WTAP_ERR_NOT_REGULAR_FILE, don't just
say the file is "invalid", say it's a "special file" or socket or some
other weird type of file.

Have the per-capture-file-type open routines "wtap_open_offline()" calls
return 1 on success, -1 if they got an error, and 0 if the file isn't of
the type that file is checking for, and supply an error code if they
return -1; have "wtap_open_offline()" use that error code. Also, have
the per-capture-file-type open routines treat errors accessing the file
as errors, and return -1, rather than just returning 0 so that we try
another file type.
Have the per-capture-file-type read routines "wtap_loop()" calls return
-1 and supply an error code on error (and not, as they did in some
cases, call "g_error()" and abort), and have "wtap_loop()", if the read
routine returned an error, return FALSE (and pass an error-code-pointer
argument onto the read routines, so they fill it in), and return TRUE on
success.
Add some new error codes for them to return.
Now that "wtap_loop()" can return a success/failure indication and an
error code, in "read_cap_file()" put up a message box if we get an error
reading the file, and return the error code.
Handle the additional errors we can get when opening a capture file.
If the attempt to open a capture file succeeds, but the attempt to read
it fails, don't treat that as a complete failure - we may have managed
to read some of the capture file, and we should display what we managed
to read.

Add to Wiretap the ability to write capture files; for now, it can only
write them in "libpcap" format, but the mechanism can have other formats
added.
When creating the temporary file for a capture, use "create_tempfile()",
to close a security hole opened by the fact that "tempnam()" creates a
temporary file, but doesn't open it, and we open the file with the name
it gives us - somebody could remove the file and plant a link to some
file, and, if as may well be the case when Ethereal is capturing
packets, it's running as "root", that means we write a capture on top of
that file.... (The aforementioned changes to Wiretap let you open a
capture file for writing given an file descriptor, "fdopen()"-style,
which this change requires.)

Provide different file types for "modified" and Red Hat 6.1 "libpcap"
files (the former have a different per-packet header, and a different
magic number, from the standard "libpcap"; the latter have the same
per-packet header as "modified" "libpcap" files, but the same magic
number as standard "libpcap" files, sigh).
Support writing "libpcap" captures in all three formats (so that, for
example, people running Ethereal on RH 6.1 can write out captures that
the "tcpdump" that comes with RH 6.1 can read, although that's not the
default format we save in - there's no way to tell whether you're
running on RH 6.1, as far as I know; "uname()" just tells you, on Linux
systems, that the kernel is Linux 2.x, and what "x" is, it doesn't say
what the *rest* of the system is).
Fix the table in "file.c" to use Olivier's code for writing Sniffer
files.

From Stephen Donnelly of Endace:
The code for reading ERF files has not been significantly
updated since 2004. This patch brings it up to date with a
number of changes.
1) Increase number of decodable ERF types from 7 to 12. This
covers newer DAG card models and firmware updates.
2) Fix timestamp conversion. Was calculating only microsecond
precision, now displaying with nanosecond resolution. Hardware
precision is 7.5 to 30 ns depending on model.
3) Allow the user to specify HDLC encapsulation as 'chdlc',
'ppp_serial', 'frelay' or 'mtp2'. This is needed because the
ERF HDLC capture formats do not include information on what
protocol is used at the next level. This is currently done via
an environment variable 'ERF_HDLC_ENCAP' and is analagous to the
existing 'ERF_ATM_ENCAP' variable.
If the user does not specify an HDLC encapsulation it tries to
guess, and falls back to MTP2 for backwards compatibility with
Florent's existing behaviour.
I know environment variables are ugly, suggestions are welcome.
4) When reading HDLC captures as MTP2, use
WTAP_ENCAP_MTP2_WITH_PHDR rather than WTAP_ENCAP_MTP2. This
allows us to put the 'Multi-Channel ERF' record 'channel
number' field into the MTP2 pseudo header > 'link_number'
field. This is then displayed in Frame information, and can
be filtered on. (Would be nice if it could be made a display
column?)
Because the ERF record does not specify whether Annex A is used
or not, we pass MTP2_ANNEX_A_USED_UNKNOWN and allow the existing
user preference to decide.
Move the MTP2_ANNEX_A_ definitions into Wiretap, make the annex_a_used
field a guint8, and change MTP2_ANNEX_A_USED_UNKNOWN to 2 so it fits in
a guint8. (This means that if you can save an ERF MTP2 file as a
libpcap file, the pseudo-header will have MTP2_ANNEX_A_USED_UNKNOWN in
it.)

Add to Wiretap the ability to write capture files; for now, it can only
write them in "libpcap" format, but the mechanism can have other formats
added.
When creating the temporary file for a capture, use "create_tempfile()",
to close a security hole opened by the fact that "tempnam()" creates a
temporary file, but doesn't open it, and we open the file with the name
it gives us - somebody could remove the file and plant a link to some
file, and, if as may well be the case when Ethereal is capturing
packets, it's running as "root", that means we write a capture on top of
that file.... (The aforementioned changes to Wiretap let you open a
capture file for writing given an file descriptor, "fdopen()"-style,
which this change requires.)

Add to Wiretap the ability to write capture files; for now, it can only
write them in "libpcap" format, but the mechanism can have other formats
added.
When creating the temporary file for a capture, use "create_tempfile()",
to close a security hole opened by the fact that "tempnam()" creates a
temporary file, but doesn't open it, and we open the file with the name
it gives us - somebody could remove the file and plant a link to some
file, and, if as may well be the case when Ethereal is capturing
packets, it's running as "root", that means we write a capture on top of
that file.... (The aforementioned changes to Wiretap let you open a
capture file for writing given an file descriptor, "fdopen()"-style,
which this change requires.)
