Details

Summary

Replace the fixed-sized array by an RB_TREE. This should both speed up
lookups and remove the 128 peer limit.

We may wish to consider adding additional trees to also speed up the
lookup by IPv4/IPv6 addresses.

Good catch.

Looks good to me.

And you may also want to retire OVPN_MAX_PEERS ;)

Thanks. I spotted that one eventually and fixed it, but figured it wasn't worth updating the review for that.
