Lua 5.3 adds several awesome features of particular interest to nmap including
bitwise operators and integers, a utf8 library, and standard binary pack/unpack
functions.
In addition to adding Lua 5.3, this branch changes:
o Complete removal of the NSE bit library (in C), It has been replaced with
a new Lua library wrapping Lua 5.3's bit-wise operators.
o Complete removal of the NSE bin library (in C). It has been replaced with a
new Lua library wrapping Lua 5.3's string.pack|unpack functions.
o The bin.pack "B" format specifier (which has never worked correctly) is
unimplemented. All scripts/libraries which use it have been updated. Most
usage of this option was to allow string based bit-wise operations which are no
longer necessary now that Lua 5.3 provides integers and bit-wise operators.
o The base32/base64 libraries have been reimplemented using Lua 5.3's new
bitwise operators. (This library was the main user of the bin.pack "B" format
specifier.)
o A new "bits" library has been added for common bit hacks. Currently only has
a reverse function.
Thanks to David Fifield, Daniel Miller, Jacek Wielemborek, and Paulino
Calderon for testing this branch.
Changes fall into these categories:
1. Avoid pathological string building. Loops over x = x .. "foo" can
become very slow. Instead, use strbuf.lua, table.concat, or just one
continuous concatenation; a = x .. y .. z is one operation, better than
a = x .. y; a = a .. z
2. Use hex-escaped strings instead of string.char. I find this more
readable in many cases, and it avoids a table lookup and function call.
3. Don't duplicate code. A few libraries and scripts had re-implemented
stdnse.generate_random_string or openssl.rand_bytes.
Mostly splitting function summaries (the first paragraph of NSEdoc) from
the body of the description to make the summary indexes shorter and
easier to scan.
Also fixed some unbalanced code tags like <code>foo</table>
1. The first paragraph of a function's NSEdoc is used as a short
summary. Some of these were very long, so I split off a shorter summary.
2. Use asterisks (*) to denote bulletted lists, not 'o'
3. Wrap lines at 80 columns
4. a couple other spelling and formatting fixes
stdnse.print_debug accepts a format string and arguments, making
string.format redundant in calls of this form:
stdnse.print_debug(1, string.format("%s: error", SCRIPT_NAME))
stdnse.print_debug(("length %d"):format(#tab))
These can be rewritten as:
stdnse.print_debug(1, "%s: error", SCRIPT_NAME)
stdnse.print_debug("length %d", #tab)

compatibility fixes to spnego authentication in smb and smbauth libraries
the spnego authentication blob now decodes properly in wireshark
fixes in spnego authentication for both Window 2003 and Windows 7
status code text when the variable status is not
nil. This mimics the behavior of start_session_extended.
This should provide more reliable results to smb-brute
concerning the nature of login failure reasons.
More detail has been sent to the mailing list.
Used this perl command:
$ # perl -pi -e 's/string\.len\((.*?)\)/#\1/g' *.lua
Also fixed one instance where the above command didn't correctly
translate the intended code (string.len(a .. b .. c)).
ms-sql scripts and library:
- Improved version detection
- Improved server discovery
- Add support for named pipes
- Add support for integrated authentication
- Add support for connecting to instances by name or port
- Improved script and library stability
- Improved script and library documentation
