Make current loglevel and current log callback global
to the library. Attaching them to the nsock pool doesn't
bring any benefit and prevents from logging activity in
code sections that don't have access to a pool (such as
proxy chain specification parsing).
Updated external calls and nsock tests accordingly.
proposal. This only affects Nmap's root directory. We might also need to
modify the code which autogenerates Nmap's source code files such as IPv6
fingerprinting code.
This call got duplicated during the merge and provoked
non-fatal nsock errors like:
NSOCK ERROR [0.0310s] nsp_set_proxychain(): Invalid call. Existing proxychain on this nsock_pool
Reworked the logging infrastructure to make it more flexible
and consistent.
Updated nmap, nping and ncat accordingly. Nsock log level can
now be adjusted at runtime by pressing d/D in nmap.
nsock_check_udata needs this parameter indicating whether to set up an
unconnected UDP socket or not. r29016 wrongly made this setup
unconditional and moved the check for connectedness into the calling
function. What went wrong is that the unconnected UDP socket could be
set up prematurely--before calling bind, for example. This broke scripts
using unconnected UDP sockets.
This was reported by Dhiru Kholia.

The exceptions are the calls in ncat/ncat_connect.c and
nping/EchoServer.cc. Ncat doesn't have an option for the interface, and
I think Nping's -e option is only meant to apply to probes, not to the
echo server listener.

socket support to NSE, with updates in scripts and libraries.
o [NSE] Added the ability to send and receive on unconnected sockets.
This can be used, for example, to receive UDP broadcasts without
using pcap. A number of scripts have been changed so that they can
work as prerule scripts to discover services by UDP broadcasting,
optionally add the discovered targets to the scanning queue:
- ms-sql-info
- upnp-info
- dns-service-discovery
The nmap.new_socket function can now optionally take a default
protocol and address family, which will be used if the socket is not
connected. There is a new nmap.sendto function to be used with
unconnected UDP sockets. [David, Patrik]
This is a maintenance fix for the NSE Nsock library binding. The patch focuses
on code correctness and simplicity. The patch also brings some initial updates
with an eye towards the upcoming Lua 5.2 release. See [1] for a post concerning
this branch.
