c9294c1a78 Prevent recursive transit of ZeroTier packets, toward GitHub issue #56 2014-04-10 14:22:25 -07:00

b117ff5435 Probable fix for GitHub issue #63 - do not unite() if either path is TCP, since doing so can result in asymmetric failed NAT-t over UDP if one side has a firewall that permits outgoing UDP but not incoming. 2014-04-10 11:17:54 -07:00

a1c1c82b0d VERSION 0.8.1
This, quick on the heels of 0.8.0, fixes the fact that TCP tunneling was
broken. :)

There was a bug that only manifested in some cases, and not on my testnet.
I took the opportunity to clean up some of that logic generally. I need a
better testnet, but that will have to wait until we exit beta and hopefully
I can earn a little bit of money off this. A better testnet will require
a big beefy virtualization box or two to run hundreds to thousands of KVMs.

Also fixed a tiny cosmetic issue on Windows. Other than that no changes.

dd404b8ba3 VERSION 0.8.0
This version introduces a major new feature requested by several users,
both via the user survey and otherwise: TCP tunneling.

If you are not able to communicate over UDP/9993, ZeroTier One will switch to
TCP connections to ZeroTier's supernodes. This is always slower than UDP, but
will allow you to communicate behind all but the most extremely restrictive
firewalls. This TCP traffic travels over port 443 and looks like HTTPS (SSL)
traffic (though it isn't), since that port is almost always open.

This also fixes several minor bugs and attempts to improve the robustness of
Windows tap driver management. Several users have reported spurious issues
with the Windows tap device, though I was unable to reproduce any of these with
clean VMs. (Tried Windows 7 and 8.1, both x86 and x64. No luck.) But I tried
to beef up the tap code anyway in the hopes of catching it. It now tries a lot
harder to make sure the tap is up and running.

There was some significant under the hood refactoring in support of TCP, so
this was a non-trivial change.

I bumped the version to 0.8 to indicate that more and more features are being
crossed off the list as we approach 1.0 and exit from beta. After this, the next
major feature will be LAN announcement to find direct paths to peers on the
same physical LAN. But assuming that 0.8.0 goes smoothly, I am going to divert
attention to the web site. A new design is coming that is much cleaner, sharper,
and easier to use.

Thank you all for all your excellent feedback! We're well on the way to a killer
product that makes conventional VPNs and other kludges obsolete.

f13493edb2 Oops... turns out we need to differentiate incoming from outgoing TCP and indeed learn incoming TCP paths. Otherwise the recipient of a TCP connection does not know to reply via TCP! Heh. 2014-03-31 22:23:55 -07:00

595b386afc Increase maximum packet fragments to make room for huge multicasts with certificates of membership tagged onto them. This likely will not actually increase the number of fragments in practice much, since these are then subsequently compressed. But the buffer needs to be allocated with room for them, otherwise these packets get dropped with a range_error exception internally. 2014-03-31 14:53:33 -07:00
