Hi,
I've committed revision 26010 with some fixes for the really obvious cases.
Please review the changes, found here:
http://anonsvn.wireshark.org/viewvc/index.py?view=rev&revision=26010
Most of the lint output is caused by:
- signed / unsigned differences
- TRY / CATCH / RETHROW macro
which could have merit, that is for further study.
Thanx,
Jaap

Some time ago when Wireshark was still Ethereal, I had run lint against
one or more of the dissectors and provided some results to the mailing
list and offered to provide lint output for more dissectors if there was
interest, but there didn't appear to be any at the time.
In case that's changed now, I thought I would run lint against a
dissector again, provide the results, and see if interests levels have
changed. I know the Wireshark code has been run against Coverity's
tools and there was a concerted effort to correct the problems it found,
so maybe there's interest in lint now too? I know lint can be very
noisy and produce tons and tons of warnings if not properly tamed, but I
think it may have found some real bugs in the TCP dissector and is worth
a look. Here are a couple of examples from the log:
_
tcpinfo->seq = msp->seq;
epan\dissectors\packet-tcp.c(1618) : Warning 613: Possible use of null
pointer
'msp' in left argument to operator '->' [Reference: file
epan\dissectors\packet-tcp.c: lines 1485, 1507]
epan\dissectors\packet-tcp.c(1485) : Info 831: Reference cited in prior
message
epan\dissectors\packet-tcp.c(1507) : Info 831: Reference cited in prior

_
char relative_modifier[10] = "(relative)";
epan\dissectors\packet-tcp.c(2477) : Info 784: Nul character truncated

Anyway, the lint output is attached for what it's worth. (I purposely
left most warnings in to make sure I didn't inadvertently mask a bug,
but I think it would be perfectly reasonable to disable several of the
warnings ... but that comes later.)
