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 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".

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".

cases, call "g_error()" and abort), and have "wtap_loop()", if the read

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

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

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 a routine that, given a set of packet encapsulation types, returns
the per-file encapsulation type needed to write out a set of packets
with all those encapsulation types. If there's only one such
encapsulation type, that's the type, otherwise WTAP_ENCAP_PER_PACKET is
needed. Use that in wtap_dump_can_write_encaps().
Also use it in cf_save_packets() and cf_export_specified_packets(), so
that we can write out files with WTAP_ENCAP_PER_PACKET as the file
encapsulation type and only one actual per-packet encapsulation type in
some cases where that failed before. This fixes the case that showed up
in bug 7505, although there are other cases where we *could* write out a
capture in a given file format but won't be able to do so; fixing those
will take more work.
#BACKPORT
(Note: this adds a routine to libwiretap, so, when backported, the
*minor* version of the library should be increased. Code that worked
with the version of the library prior to this change will continue to
work, so there's no need to change the *major* version of the library.)

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,

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.)
