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

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

Update generate.sh (#736) 
The AppArmor profile in contrib forbids `/usr/bin/yggdrasil` from reading the file in `/var/backups/yggdrasil.conf...`. This works around that restriction by having the shell do the reading of `/var/backups/yggdrasil.conf...` file while providing the same exact functionality without making the AppArmor profile less restrictive. 

Another change is the safe perms for the `/etc/yggdrasil.conf` (so that config will have 0640 permissions). This is important because if we kept the default of 644 then any user (privileged or unprivileged) will have the ability to read the yggdrasil private key. We use a restrictive umask of 0027 to make this possible.

apparmor: allow yggdrasil to resolve hostnames (#739) 
The apparmor profile in it's current state won't allow resolving hostnames. We need `<abstractions/nameservice>` because we simply can't just allow `/etc/resolv.conf`. This is because systemd-resolved, resolvconf, and others rely on symbolic links to `/etc/resolv.conf` which would make this extremely complicated.  `<abstractions/nameservice>` deals with this complexity to allow every single one of those packages (systemd-resolved, resolvconf, ... ).

```
  network inet stream,
  network inet dgram,
  network inet6 dgram,
  network inet6 stream,
  network netlink raw,
```
was removed because it's already included in `<abstractions/nameservice>`. Some permissions that are no longer needed in newer yggdrasil versions were also removed.

`owner /sys/kernel/mm/transparent_hugepage/hpage_pmd_size r,` was changed to `/sys/kernel/mm/transparent_hugepage/hpage_pmd_size r,` because there is no guarantee that yggdrasil will always be run as root. (`owner` makes sure that the process's user and the file have the same owner, in that case, root. This might not always be the case so `owner` was removed)

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.
