Don't return a value from "dissect_h4501()" - the value isn't used, and
"dissect_h4501()" is registered with "register_dissector()", so it's not

For those that don't, replace "Unknown" with NULL; "Unknown" is now

layer byte in the reassembled data - including it means we have to pass
to "tvb_new_real_data()" a pointer to the *second* byte of a mallocated
chunk of data, but that would require us to have the free routine for
the new tvbuff back that pointer up before freeing it (we aren't doing
that currently, which means that "free()" either complains bitterly or,
potentially, corrupts the arena, causing crashes later).
Put in some XXX comments about some issues seen when looking at the
code.

Add a DISSECTOR_ASSERT() macro, which is the usual type of assertion
macro, but throws a DissectorError exception with a message giving the
flien and line number and the failed test as a string. Use that macro
in "alloc_field_info()".
Report that exception in the Info column and the protocol tree, as well
as logging the exception failure with g_warning().

don't dissect attributes if there aren't any;

Use "match_strval()" to check whether the message type is a known STUN

Don't use "tvb_bytes_exist()" to check when we run out of data - use the

updates and enhancements:
- Added Cookie and L2-Specific sublayer support via preferences dialog.
- Added carried payload dissecting support from draft-ietf-l2tpext-pwe3-*
and draft-townsley-l2tpv3-mpls-02.txt
- Completed missing message types (call types) and result codes for stopccn
and cdn.
- Fixed conditionals for avp_vendor_id (Vendor-Specific AVPs)
- Changed Pseudowire Capabilities List AVPs to use subtree instead of tab
- Added numeric value of result and error codes
- Added Session ID for v3 data packets and missing flags and reserved
- Added version to the L2TPv3 protocol tree
- Changed `Tunnel Id' to `Control Connection Id' for v3
- Fixed offset for ctrl_tree on L2TPv3 over UDP
- Added `L2TPv3' in the COL_PROTOCOL and fixed handling of L2TP version

that doesn't mean it's padding at the end of a previous item - it might,
for example, be the *first* item in the chunk. Don't treat it as
padding.
Do, however, treat an item that begins with a zero byte as an item, but
break out of the loop processing items as soon as the item type is put
into the protocol tree, as there's no length field or data in an
RTCP_SDES_END item. Fix the comment for that loop to indicate that the
loop checks both for end-of-frame and for an RTCP_SDES_END item.

Add VENDOR_IETF to <epan/sminmpec.h>, and add an entry for it to

Clean up indentation.
The signatures are 4-byte strings - treat them as such.
Don't hide fields - dissectors should show what all bytes, other than
perhaps padding bytes, are.
Don't use the tvb_format_text-ified versions of strings as the value -
Ethereal already deals with non-printable characters when displaying
them.
When creating a subset tvbuff that runs to the end of the parent, use -1

Use "tvb_reported_length()", not "tvb_length()", in loops that parse the

Use "format_text()" or "tvb_format_text()" with the %s format, to handle
non-printable characters.
When uncompressing data into a new tvbuff, add it to the list of data
sources as we do elsewhere.
When putting items into the protocol tree from an uncompressed tvbuff,
use the offset into the tvbuff and the length of the item.
Fetch string lengths into a variable and use the variable rather than
repeatedly fetching the length from a tvbuff.
Use -1 rather than tvb_length_remaining() when putting a "to the end of
the tvbuff" item into the protocol tree.
Use "proto_tree_add_item()" to put items into the tree, rather than
"proto_tree_add_xxx" calls with a "tvb_get_yyy" call as the argument.
If we've fetched a value into a variable, don't re-fetch it in
"proto_tree_add_xxx" calls.

const pointer (so that we don't get complaints when we make the
tap-specific data argument to "tap_queue_packet()" a const pointer,
allowing dissectors to hand const data to a tap without a complaint), we
should make the tap per-packet function take a const pointer as an
argument as well. Do so.
In some taps, use _U_, or actually use the argument, rather than
sticking in dummy "X = X" assignments to fake use of parameters. (This
means that the tap functions in question no longer have the notion that
they act on a particular static structure wired in.)

Don't assign the const pointers passed to hash routines to non-const
pointers.
In "zonenm_to_str()", don't assume there's a null terminator in the

Don't assign the const pointers passed to hash routines to non-const
pointers.
Don't use "tvb_get_ptr()" to get a pointer to a data structure, and
dereference that pointer - there's no guarantee that the structure in
question will be located on an appropriate boundary in the data from the
packet (regardless of whether it's properly aligned within the data for
the protocol being dissected).
Put the record length for an EFP request into the protocol tree.
Check the sanity of the payload length for that request.
In "zonenm_to_str()", don't assume there's a null terminator in the

Don't assign the const pointers passed to hash routines to non-const

Don't assume that strings the spec says are null-terminated are

appropriate exception if no null is found.
