* TunnelsManager: initialize observer on correct threadJason A. Donenfeld2018-11-031-5/+7
| | | | | | Because of the callback recursion, this function needs to always be called from the right thread Signed-off-by: Jason A. Donenfeld <Jason@zx2c4.com>
* TunnelsManager: do not track currentTunnelJason A. Donenfeld2018-11-031-33/+6
| | | | | | It's error prone and does not give us anything. Signed-off-by: Jason A. Donenfeld <Jason@zx2c4.com>
* TunnelsManager: do not change back to inactive if we are resolving the endpointJason A. Donenfeld2018-11-031-0/+5

* TunnelsManager: get rid of name setJason A. Donenfeld2018-11-031-16/+4
| | | | | | | Instead, tunnels itself should be a sorted-set. For now it's a list, which is probably fine though. Signed-off-by: Jason A. Donenfeld <Jason@zx2c4.com>
* TunnelsManager: get rid of index managementJason A. Donenfeld2018-11-031-47/+27
| | | | | | | No need for premature optimization. There aren't that many tunnels most of the time, and calling sort on a partially sorted array is fast. Signed-off-by: Jason A. Donenfeld <Jason@zx2c4.com>
