a layer 4 protocol used mostly for telephony related applications.
This brings the following new features:
o SCTP INIT chunk port scan (-sY): open ports return an INIT-ACK
chunk, closed ones an ABORT chunk. This is the SCTP equivalent
of a TCP SYN stealth scan.
o SCTP COOKIE-ECHO chunk port scan (-sZ): open ports are silent,
closed ports return an ABORT chunk.
o SCTP INIT chunk ping probes (-PY): host discovery using SCTP
INIT chunk packets.
o SCTP-specific IP protocol scan (-sO -p sctp).
o SCTP-specific traceroute support (--traceroute).
o The ability to use the deprecated Adler32 algorithm as specified
in RFC 2960 instead of CRC32C from RFC 4960 (--adler32).
o 42 well-known SCTP ports were added to the nmap-services file.
Part of the work on SCTP support was kindly sponsored by
Compass Security AG, Switzerland. [Daniel Roethlisberger]
Some scripts would fail due to an error (whois.nse) causing other
scripts to become deadlocked on a mutex that would never unlock. This
patch fixes this problem. See [1] for more information.

("and", "or", or "not") combined with categories, filenames, and filenames with
a '*', wildcard, to match many files. This change requires the script database
to be recompiled. Please see the thread at
http://seclists.org/nmap-dev/2009/q2/0100.html for more information.
Changed the garbage collection cycle after all threads in running are run
from a step to a full collection cycle. It can take quite a few steps before
sockets are finally collected so other threads may finish making a connection.
Moved the includes for Lua headers to the .cc files so they are
not needlessly, repeatedly included.
Similarly, moved some standard headers to the .cc files and reorganized
includes to be uniform for all nse_* source files.
Fixed whitespace (removed tabs).
script event: start, finish, timeout, and error. The file name is now stored as
a std::string in struct thread_record so we have it when we don't have access
to the thread's environment.
The script's filename cannot be acessed when a thread's target times out
because we do not have access to the thread's environment when it is yielded.
All we can do is print out which target timed out. This output can
unfortunately be printed out many times for each thread (it is currently
difficult to track).
nse_main and nse_nsock. nse_main now uses Lua to create printable output
while a cleaner hexify procedure has been placed in nsock.
nse_string is removed as a result.
Now does most of it's work through Lua:
From Nmap-dev: "Many of the changes consist of changing how Nmap interfaces
with Lua that were sometimes awkward or inflexible. Most of the functions
have been made to be callable directly by Lua which offers many technical
advantages: stack management is alleviated, errors are handled cleanly and
are more descriptive, and there is increased reusability."
Additionally:
-- Moved all lua_State * symbols from "l" to "L". This is to maintain
consistency with other Lua libraries (convention) and to make our macros portable.
-- Moved file system manipulation over to nse_fs.cc (from nse_init.cc)
