Selfm Dissector Patch 07-02-2013 - Fixes for Evan's Comments
A few compiler errors with cutting-edge GCC:
packet-selfm.c:855:1: error: "/*" within comment [-Werror=comment]
packet-selfm.c:1467:41: error: variable 'config_found' set but not used
packet-selfm.c:1571:59: error: 'data_size' may be used uninitialized in this
function
tools/cppcheck/cppcheck.sh points out a pair of unused assignments:
epan/dissectors/packet-selfm.c:1354: warning: Assignment of function parameter
has no effect outside the function.
epan/dissectors/packet-selfm.c:1441: warning: Assignment of function parameter
has no effect outside the function.
tools/checkAPIs.pl has a few complaints:
Error: the blurb for hf_selfm_fragment ("selfm.respdata.fragment") matches the
field name in epan/dissectors/packet-selfm.c
Error: the blurb for hf_selfm_fragments ("selfm.respdata.fragments") matches
the field name in epan/dissectors/packet-selfm.c
tools/checkhf.pl has a complaint:
Unused entry: epan/dissectors/packet-selfm.c, hf_selfm_fastser_soe_resp_data
If I hack it enough to make it compile, I get the following warnings when
testing it on the sample capture:
WARNING **: Extended value string selfm_msgtype_vals forced to fall back to
linear search: entry 1, value 42310 < previous entry, value 42425
WARNING **: Extended value string selfm_relaydef_proto_vals forced to fall back
to linear search: entry 4, value 1 < previous entry, value 768
