epan/show_exception.c, as it's used outside
epan/dissectors/packet-frame.c. Update their callers to include
<epan/show_exception.h> to get their declaration.
Add a CATCH_NONFATAL_ERRORS macro that catches all exceptions that, if
there's more stuff in the packet to dissect after the dissector call
that threw the exception, doesn't mean you shouldn't go ahead and
dissect that stuff. Use it in all those cases, including ones where
BoundsError was inappropriately being caught (you want those passed up
to the top level, so that the packet is reported as having been cut
short in the capture process).
Add a CATCH_BOUNDS_ERRORS macro that catches all exceptions that
correspond to running past the end of the data for a tvbuff; use it
rather than explicitly catching those exceptions individually, and
rather than just catching all exceptions (the only place that
DissectorError should be caught, for example, is at the top level, so
dissector bugs show up in the protocol tree).
Don't catch and then immediately rethrow exceptions without doing
anything else; just let the exceptions go up to the final catcher.
Use show_exception() to report non-fatal errors, rather than doing it
yourself.
If a dissector is called from Lua, catch all non-fatal errors and use
show_exception() to report them rather than catching only
ReportedBoundsError and adding a proto_malformed item.
Don't catch exceptions when constructing a trailer tvbuff in
packet-ieee8023.c - just construct it after the payload has been
dissected, and let whatever exceptions that throws be handled at the top
level.
Avoid some TRY/CATCH/ENDTRY cases by using checks such as
tvb_bytes_exist() before even looking in the tvbuff.

Specifically: Replace FALSE|0 and TRUE|1 by ENC_BIG_ENDIAN|ENC_LITTLE_ENDIAN as
the encoding parameter for proto_tree_add_item() calls which directly reference
an item in hf[] which has a type of:
FT_BOOLEAN
FT_IPv4
FT_EUI64
FT_GUID
FT_UINT_STRING
Also: For type FT_ITv6 use ENC_NA. (This was missed in SVN #39260)

This is necessary in case a subdissector had changed it but was unable to
restore it (due to the exception).
Remove check_col().

1) Rollback r14139 in two parts:
a) Change user priority back to what Cisco's ISL documentation states that
the values mean instead of the 802.1Q CoS values (see also note below).
b) Change the destination address back to type FT_ETHER since the
ISL-Frame values were added to manuf/wka.tmpl in r16741 with a /40
mask.
2) Add 03-00-0C-00-00/40 to manuf/wka.tmpl for ISL over Token Ring.
3) Move the type and user fields to a tree elow the destination address since
that is where the values come from.
NOTE: Regarding change 1a, I noticed in the Wiki's isl-2-dot1q.cap sample
capture file that bit #2 is being set to 1 when bits 0 and 1 are set to
1. When bits 0 and 1 are both set to 0, bit 2 is not set. I cannot
find a reference to this bit being used in Cisco's documentation.

- Bring URLs at top of file up to date.
- Replace redundant true false string (bpdu_tfs) with built-in one (tfs_yes_no)
- Change VLAN ID representations from hex to decimal
- Change description (but not filter name) for BPDU indicator to indicate that,
per Cisco documentation, it is set when it is not only a BPDU frame but also
set for CDP and VTP frames.
- Add "(Color)" to VLAN ID field descriptions for nostalgic reasons :)

(1) Trailing/leading spaces are removed from 'name's/'blurb's
(2) Duplicate 'blurb's are replaced with NULL
(3) Empty ("") 'blurb's are replaced with NULL
(4) BASE_NONE, NULL, 0x0 are used for 'display', 'strings' and 'bitmask' fields
for FT_NONE, FT_BYTES, FT_IPv4, FT_IPv6, FT_ABSOLUTE_TIME, FT_RELATIVE_TIME,
FT_PROTOCOL, FT_STRING and FT_STRINGZ field types
(5) Only allow non-zero value for 'display' if 'bitmask' is non-zero

This patch adds a heuristic dissector to the ethernet trailer under the
keystring "eth.trailer". This allows for other protocol plugins which coopt
the ethernet trailer for their own devices to register for trailer traffic
without requiring any further changes to the executable.

be moved to epan/dissectors, if they pertain only to stuff exported by a
particular dissector.

My patch changes the decoding of the Destination address to conform with the
spec found at http://www.cisco.com/univercd/cc/td/doc/product/lan/trsrb/frames.htm#xtocid75
and adds decoding of user field values 4-7 while updating the description of
user field values 0-3 according to IEEE 802.1D-2004, annex G.

Ethernet frames, one for encapsulated frames that include an FCS and one
for encapsulated frames that don't include an FCS. Use the appropriate
versions.
In the ISL dissector, do the same sort of processing we do in the
Ethernet dissector to figure out whether the frame has a trailer or not
and whether it has an FCS or not.

files.
