Yet another revision of this algo... yeesh... and update to supernode IDs. I think I am gonna go with this one. Seems memory-hard enough to me. I am probably procrastinating by obsessing over it.

Make Salsa20 variable-round, allowing for Salsa20/12 to be used for Packet encrypt and decrypt. Profiling analysis found that Salsa20 encrypt was accounting for a nontrivial percentage of CPU time, so it makes sense to cut this load fundamentally. There are no published attacks against Salsa20/12, and DJB believes 20 rounds to be overkill. This should be more than enough for our needs. Obviously incorporating ASM Salsa20 is among the next steps for performance.

Add a second arg to idtool generate to make generating both secret and public easier, add new supernode identities after generating them, fix known good and bad IDs in selftest.

Make new identity hashcash algo memory hard, and tweak generation time a bit. Current hashcash cost should be overkill for what we need but still tolerable to users.

Tap works! At least in isolation. Time to create the Windows executable and the Windows service to run it and handle auto-update.

Commit of a draft of the pcap-based strategy for a Windows tap. This may, in the end, not work, since winpcap may not support immediate capture and also because some software flags winpcap as malware. Like I said, trying to do anything interesting with Windows is PAIN.

Version 0.4.3 (the real one): fix Gentoo ip config failures and crashes
...
This version fixes problems with locating the 'ip' command on Gentoo
and possibly other Linux systems, and a problem that could cause a
crash if EthernetTap was unable to locate one of the commands it
invokes to configure IP information on tap devices.
The code also now builds on Windows. It doesn't run yet, but it's a
step. Windows port is in full swing.
Finally, the multicast rate limit defaults were raised a little. More
testing is needed here, and real world measurments.

Stop using RAND_ in libcrypto for Utils::getSecureRandom() due to annoying valgrind spew from libcrypto use of uninitialized RAM as a random source. Might look into replacing RAND_ in libcrypto with our own simple /dev/urandom / Windows CAPI plugin.

Several things:
...
(1) Probable fix for issue #7 and major cleanup of EthernetTap code with consolidation for all unix-like systems and specialization for different flavors only when needed.
(2) Refactor of Buffer<> to make its members private, and Packet to use Buffer's methods exclusively to access them. This improves clarity and means we're no longer lying about Buffer's role in the code's security posture.
(3) Add -fstack-protect to Makefile to bounds check stack variables.
