2015-10-05wslua: fix crash when a LUA error is raised in TRY blockPeter Wu1-5/+9
The dissect_tcp_pdus function in LUA is passed two LUA functions that get the PDU length and the dissect a PDU. When one of these functions fail, a longjmp is made to the the caller of lua_pcall. This is no problem for the PDU length function, but the PDU dissect function is wrapped in a TRY/CATCH/ENDTRY block which also uses longjmp and need to be fully executed. Without doing so, LUA exceptions will crash on a weird location (except_pop). Fix the crash by not using luaL_error, but throw dissector errors which properly breaks out of the tcp_dissect_pdus C function and then convert it to a LUA error such that the dissector can handle it. Test with `tshark -X lua_script:crash.lua -r ssl.pcap`: trivial_proto = Proto("trivial", "Trivial Protocol") function dissect_foo(tvb, pinfo, tree) error("triggering a LUA error"); end function get_pdu_len(tvb, pinfo, tree) return 5; end function trivial_proto.dissector(tvb, pinfo, tree) dissect_tcp_pdus(tvb, tree, 5, get_pdu_len, dissect_foo) end tcp_table = DissectorTable.get("tcp.port") tcp_table:add(443, trivial_proto) It should not crash and will print this: Lua Error: dissect_tcp_pdus dissect_func: [string "crash.lua"]:3: triggering a LUA error Change-Id: Ibd079cc5eb3a2e4d2e62ea49a512fa2cc8e561ea Reviewed-on: https://code.wireshark.org/review/10685 Petri-Dish: Peter Wu <peter@lekensteyn.nl> Tested-by: Petri Dish Buildbot <buildbot-no-reply@wireshark.org> Reviewed-by: Peter Wu <peter@lekensteyn.nl> Reviewed-by: Evan Huus <eapache@gmail.com>

errors. A common Lua idiom is to use chained calls, i.e. tree:foo():bar():choo(). This actually works for tree:add() because it returns the new child tree item which is then the one being applied to the next chained call. But it doesn't work beyond that for things like set_generated() and so on. So this commit fixes that. This also fixes the Lua tree:add() function for the FT_BOOL type to let it be a Lua boolean value. And it reverts a previous change to Struct.tohex() to allow coercion of the argument.

2014-03-26Add filterable expert info for LuaHadriel Kaplan1-3/+187
This adds the ability for a Lua script to register expert info fields, similar to C-code dissectors. This change also removes the need for the expert_add_info_format_internal() function. Existing Lua scripts do not have to change, because the existing expert info function uses the internal "_ws.lua" protocol instead of nothing; but using the new functionality provides more benefits since it correctly registers the expert info fields to the dissector's protocol. The test suite was amended to generate both old and new forms.

2014-03-25Enhance Lua API doc generator and add more API infoHadriel Kaplan1-307/+396
This enhances the Lua API doc generator Perl script to handle meta-information in description comments, such as bold, italics, raw code, version info, etc. The supported markup and codes are documented in make-wsluarm.pl. It's not beautiful Perl code (I don't know Perl), and I'd rather do it using Lua, but I think keeping it Perl makes more sense in the long run.

2014-03-14Add Lua heuristic dissector supportHadriel Kaplan1-0/+134
This adds the ability for Lua scripts to register heuristic dissectors for any protocol that has registered a heuristic dissector list, such as UDP, TCP, and ~50 others. The Lua function can also establish a conversation tied to its Proto dissector, to avoid having to check the heuristics for the same flow. The example dissector in the testsuite has also been enhanced to include a heuristic dissector, to verify the functionality and provide an example implementation.
