|
|
|
|
* - Playback window
|
|
|
|
* - Multiple window support
|
|
|
|
* - Add cut/copy/paste
|
|
|
|
* - Create header parsing routines
|
|
|
|

Have "close_cap_file()" disable all menu items that make sense only if
you have a capture.
Leave the job of enabling and disabling menu items that make sense only
if you have a capture (except for "File/Save" and "File/Save As...", for
now) up to "load_cap_file()", "close_cap_file()", and the like - don't
scatter that stuff throughout the code.
Disable "File/Print Packet" if no packet is selected; enable it only if
a packet is selected.
If there's a selected packet, and a display filter is run:
if the selected packet passed the filter, re-select it;
if the selected packet didn't pass the filter, un-select it.
If we've opened a live "pcap" capture, but can't do the capture because
we can't get the netmask info, or can't parse the capture filter string,
or can't install the filter, close the live capture and the dump and
delete the dump file.
If we failed to open a live "pcap" capture, don't try to read the
capture file - it doesn't exist.

Improve the alert boxes put up for file open/read/write errors. (Some
influence came from
http://developer.apple.com/techpubs/mac/HIGuidelines/HIGuidelines-232.html
which has a section on dialog box and alert box messages. However,
we're largely dealing with technoids, not with The Rest Of Us, so I
didn't go as far as one perhaps should.)
Unfortunately, it looks like it's a bit more work to arrange that, if
you give a bad file name to the "-r" flag, the dialog box pop up only
*after* the main window pops up - it has the annoying habit of popping
up *before* the main window pops up, and sometimes getting *obscured* by
it, when I do that. The removal of the dialog box stuff from
"load_cap_file()" was intended to facilitate that work. (It might also
be nice if, when an open from the "File/Open" menu item fails, we keep
the file selection box open, and give the user a chance to correct
typos, choose another file name, etc.)

needn't do any X stuff at all when so invoked.
That allows Ethereal to be built in an environment where you don't have

you to built it faster.

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.)

DLT_NULL, from "libpcap", means different things on different platforms
and in different capture files; throw in some heuristics to try to
figure out whether the 4-byte header is:
1) PPP-over-HDLC (some version of ISDN4BSD?);
2) big-endian AF_ value (BSD on big-endian platforms);
3) little-endian AF_ value (BSD on little-endian platforms);
4) two octets of 0 followed by an Ethernet type (Linux, at least
on little-endian platforms, as mutated by "libpcap").
Make a separate Wiretap encapsulation type, WTAP_ENCAP_NULL,
corresponding to DLT_NULL.
Have the PPP code dissect the frame if it's PPP-over-HDLC, and have
"ethertype()" dissect the Ethernet type and the rest of the packet if
it's a Linux-style header; dissect it ourselves only if it's an AF_
value.
Have Wiretap impose a maximum packet size of 65535 bytes, so that it
fails more gracefully when handed a corrupt "libpcap" capture file
(other capture file formats with more than a 16-bit capture length
field, if any, will have that check added later), and put that size in
"wtap.h" and have Ethereal use it as its notion of a maximum packet
size.
Have Ethereal put up a "this file appears to be damaged or corrupt"
message box if Wiretap returns a WTAP_ERR_BAD_RECORD error when opening
or reading a capture file.
Include loopback interfaces in the list of interfaces offered by the
"Capture" dialog box, but put them at the end of the list so that it
doesn't default to a loopback interface unless there are no other
interfaces. Also, don't require that an interface in the list have an
IP address associated with it, and only put one entry in the list for a
given interface (SIOCGIFCONF returns one entry per interface *address*,
not per *interface* - and even if you were to use only IP addresses, an
interface could conceivably have more than one IP address).
Exclusively use Wiretap encapsulation types internally, even when
capturing; don't use DLT_ types.

#ifdef HAVE_LIBPCAP

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.)

DLT_NULL, from "libpcap", means different things on different platforms
and in different capture files; throw in some heuristics to try to
figure out whether the 4-byte header is:
1) PPP-over-HDLC (some version of ISDN4BSD?);
2) big-endian AF_ value (BSD on big-endian platforms);
3) little-endian AF_ value (BSD on little-endian platforms);
4) two octets of 0 followed by an Ethernet type (Linux, at least
on little-endian platforms, as mutated by "libpcap").
Make a separate Wiretap encapsulation type, WTAP_ENCAP_NULL,
corresponding to DLT_NULL.
Have the PPP code dissect the frame if it's PPP-over-HDLC, and have
"ethertype()" dissect the Ethernet type and the rest of the packet if
it's a Linux-style header; dissect it ourselves only if it's an AF_
value.
Have Wiretap impose a maximum packet size of 65535 bytes, so that it
fails more gracefully when handed a corrupt "libpcap" capture file
(other capture file formats with more than a 16-bit capture length
field, if any, will have that check added later), and put that size in
"wtap.h" and have Ethereal use it as its notion of a maximum packet
size.
Have Ethereal put up a "this file appears to be damaged or corrupt"
message box if Wiretap returns a WTAP_ERR_BAD_RECORD error when opening
or reading a capture file.
Include loopback interfaces in the list of interfaces offered by the
"Capture" dialog box, but put them at the end of the list so that it
doesn't default to a loopback interface unless there are no other
interfaces. Also, don't require that an interface in the list have an
IP address associated with it, and only put one entry in the list for a
given interface (SIOCGIFCONF returns one entry per interface *address*,
not per *interface* - and even if you were to use only IP addresses, an
interface could conceivably have more than one IP address).
Exclusively use Wiretap encapsulation types internally, even when
capturing; don't use DLT_ types.

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.
