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.
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.
Instead of basing everything on URLs, the transport hopping now actually supports the creation of a whole new transport on the fly. The transport instance is stored in the remote as a "next transport" pointer.
This better facilitates the notion of being able to set all of the parameters on the transport when doing the switch, and is a step closer to being able to support chains of transports.
The transport refactor appears to be working, but the transport swtching
requires more work on the side of stageless posix before it will work.
At the moment, the POSIX implementation of the transport switching is
commented out so that it can't be used or built into the binaries.
This should mean we can move forward on other friends without this
holding us back.
Switching works, but doesn't do anything nice with session management. Still need to get things wired into posix, and probably rip out the wininet stuff as well given that I probably won't refactor it to support this.
* Transports are now defined by a set of callbacks that are bound to the Remote.
* Transport initialisation and dispatching is seprated.
* The context of the transport should be switchable depending on new transport requirements.
More to do, but it has begun.
Tweak the SSL implemention so that for https meterpreters the SSL certificate is validated against a hash that is specified in the payload. If the hash isn't specified, then certificate validation isn't attempted.
* Added the doxygen binaries and configuration.
* Added a `make docs` which generates documentation to the `docs` folder.
* Added some documentation to various areas of the source that I was
working with. Over time I'll be adding more and more rather than trying
to do it all in one hit.
* Refactored the kitrap0d code a bit to try to reduce code size.
