* man: update wg-quick(8) to show Debian resolvconf braindamageJason A. Donenfeld2017-05-301-2/+2
| | | | | | | | | | | | | | | | | | | | While OpenResolv supports explicit ordering directives such as `-m` and exclusivity directives such as `-x`, Debian's own resolvconf supports none of this, instead using a hard coded list of interface name templates for determining ordering. While trying to emulate `-x` is difficult [*], we can at least try to mostly emulate `-m 0` by masquerading as a `tun*` interface to resolvconf. Ugly, but it works. [*] One heavy handed way of emulating `-x` would be something like: # echo nameserver 8.8.8.8 > /etc/resolv.conf.wg0-exclusive # mount --bind -o ro /etc/resolv.conf.wg0-exclusive /etc/resolv.conf # rm -f /etc/resolv.conf.wg0-exclusive This in practice works quite well, but is a bit heavy to put in a man page. It also doesn't "stack" well. For example, if we simply run `umount /etc/resolv.conf`, how do we know which resolv.conf entry we're unmounting?

* wg-quick: use src routing for default routes in v6Jason A. Donenfeld2017-05-181-3/+11
| | | | | Otherwise, traffic is sent with the IP address of a different interface, and then packets don't actually get delivered.

* routingtable: rewrite core functionsJason A. Donenfeld2017-04-215-439/+634
| | | | | | | | | | | | | | | | | | | | | When removing by peer, prev needs to be set to *nptr in order to traverse that part of the trie. The other remove by IP function can simply be removed, as it's not in use. The root freeing function can use pre-order traversal instead of post-order. The pre-order traversal code in general is now a nice iterator macro. The common bits function can use the fast fls instructions and the match function can be rewritten to simply compare common bits. While we're at it, let's add tons of new tests, randomized checking against a dumb implementation, and graphviz output. And in general, it's nice to clean things up.

* data: alloca is actually as dangerous as they sayJason A. Donenfeld2017-04-091-6/+4
| | | | | | | | | | | | | It turns out that calling alloca from an inline function means that the memory isn't ever deallocated until the caller function exits, which means we were using tons of stack space for every iteration of the call. So, we hard code the sg array. While 128 seems like a reasonable number, we actually wind up using "MAX_SKB_FRAGS * 2 + 1". An skb has its data segment, so that's 1. Then it has its frags, which are MAX_SKB_FRAGS at max. Then it has its frag list, which, so far as I can tell, are potentially unbounded. So we just hope it's no more than MAX_SKB_FRAGS, and so we plan for at most two of those.
