a8810c7ee9 if the link handler exits early due to an existing connection, then have it return a channel to that connection which closes when the connection is closed, so we can choose to block on that to avoid spamming connection attempts with dial 2020-12-13 16:29:03 -06:00
Arceliar
1daf3e7bd7 remove link.go block on oldIntf if we already have a connection to the same node, this spams connections, so it's not a good long-term fix if that's where the goroutine leak is 2020-12-13 16:16:14 -06:00

Fix DefaultIfName for OpenBSD

Change DefaultIfName from "/dev/tun0" to "tun0" 
Specifying the full path to the interface in OpenBSD would result in:
panic: Interface name must be tun[0-9]*

Therefore, DefaultIfName should be changed to tun0 in order to make yggdrasil work out of the box.

The codebase uses int and unit16 to represent MTU randomly. This change
unifies it to a MTU type from types package, which is currently uint16.

util: fix possible OOB in IPv4 flowkey calc, use switch there 
ihl may grow upto 15*4=60 so extract and check it before using it as offset in flowkey calculation.
also replace IFs with switches for protocol matching as it's less redundant and nicer to document.
