This PR removes both log file and console output from kiwi. This is done so that those people who are unfortunate enough to migrate to a console app before running kiwi don't end up rendering all of the console output to a window that the user can see.
Transport hopping checks for prev/next weren't right. Also, moving from TCP comms was resulting failure due to the fact that it's close to impossible to get Windows to flush the buffer to MSF prior to terminating the socket without doing all kinds of horrible stuff to the socket options (which would ultimately bloat the stagers).
Instead we rely on MSf to clean things up.
Users can now add transports without switching to them straight away. They can then move forward and backwards using the next and prev commands in MSF. There's also the get UUID facility too.
Migration now works again, and supports all the transports while migrating as well. At the moment we don't have the ability to take extensions across as well, though that might come when we have fixed up the issues with stageless meterpreter.
Creation of transports for switching is done a little differently now. But the transports do cycle correctly now when things fail, each with their respective retry times.
Lots of transported related things were in the core library which didn't make any sense given that the only thing that needed it was metsrv. This moves the functionality out into metsrv, reformats stuff and gets rid of some dead code.
TODO: Make this work with POSIX.
This changeset fixes an issue with POSIX failing to keep track of loaded
extensions properly. The timeout calcs for waiting were trying to be too
smart and hence were simplified.
Also added another flush when reconnecting so that the body of the
second instance of metsrv is ignored by the POSIX side. In future, when
stageless meterpreter works with POSIX, we won't have to do this.
Currently, the select timeout on the server socket is 100 ns, meaning that
while idle, the process can wake up 100k times per second. This switches the
timeout to 0.5 second, reducing the idle CPU usage and seemingly increasing
the reliability of posix meterpreter as well.
Tested with various test post test modules without failures.
This commit includes code which will allow for HTTP/S payload URIs to be hot-patched by the server without losing the UUID information. This was put in so that the stageless payloads can be used over and over again and not have issues with session URIs colliding.
The mechanism used for validation of the SSL cert string was the same as for many of the other global replacement options. However, the string value that was used for checking was also the same. The result was that the patch mechanism wasn't patching the right instance of the string.
DERP!
Why this hit stageless only I'm really not sure.
Updated the code so that the TCP stuff is moved into its own file and doesn't pollute the main server file with stuff that is specific to TCP transports.
Updated the winhttp functionality in the same way so that functionality is properly segregated.
Modified the global parameters so that they're part of a structure that can be passed around.
Added a stack of documnetation as well.
