2f00ae4fd7 Version 0.6.1: minor bug fix, DBM removal
This version removes the peer DBM present in earlier releases. It is not necessary for
regular clients and has been a source of problems.

There is a long-term identity cache that can be enabled by making a directory called
"iddb.d" in the home folder and restarting ZT1. This is probably something only our
supernodes would need, since regular nodes can easily WHOIS peers they've forgotten
about.

On shutdown, the peer database is dumped to disk. It's then restored on startup.
Peers that have not been used in a while are cleaned out, so this keeps this data
set small.

A DBM may re-appear later if it's needed, but for now it was YAGNI.

5e71e07f59 Add persistent identity caching for use on supernodes. Activate by just making an iddb.d directory in the ZeroTier home folder. Also clean up some obsolete cruft from makefiles. 2013-10-21 14:12:00 -04:00

40e4f39181 Peers are now dumped on shutdown in a persistence cache and reloaded on startup, which is good enough for clients right now. Supernodes will get something else for long-term authoritative identity caching. 2013-10-21 11:15:47 -04:00

6e217dfcb0 Get rid of DBM, which technically is a case of YAGNI. Supernodes will need a way to save identities, but that can be a different feature. Regular clients do not really need a permanent cache (yet). When/if we do need one we can do it then. Until then it only caused problems. 2013-10-21 10:29:44 -04:00

bad043729f 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. 2013-10-20 15:31:32 -04:00

8c9b73f67b 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. 2013-10-18 17:39:48 -04:00
