This means grappling with the use + of epoch there, and either making nvl allocations not sleep, or doing nvl + allocations outside of epoch critical sections, or possibly deciding epoch + doesn't actually matter there because we're holding an sx. +- Rework locking and epoch lifetimes; come up with consistent set of rules. +- Chop off padding on rx after verifying lengths, so that tcpdump doesn't see + zeros. +- Shore up vnet support and races/locking around moving between vnets. +- Work out `priv_check` from vnet perspective. (There's no `ns_capable()` on + FreeBSD, just `capable()`, which makes it a bit weird for one jail to have + permissions in another.) +- Resize mbufs once at the beginning, and then encrypt/decrypt in place, rather + than making a new mbuf and copying. (Remember to clear the tags and other + pieces of metadata before passing it off to udp sending or netisr receiving.) +- Check nonces in serial, rather than in parallel. (This requires taking a + keypair reference; ncon is working on it.) +- Audit allowedips / radix tree checks, and make sure it's actually behaving as + expected. (It might be useful to port [this selftest](https://git.zx2c4.com/wireguard-linux/tree/drivers/net/wireguard/selftest/allowedips.c).) +- Make code style consistent with one FreeBSD way, rather than a mix of styles. + +### Crypto TODO + +- Do packet encryption using opencrypto/ with sg lists on the mbuf, so that we don't need to linearize mbufs. +- Send 25519 upstream to sys/crypto, and port to it. +- Send simple chapoly upstream to sys/crypto, and port to it. +- Port to sys/crypto's blake2s implementation. + +### Tooling TODO + +- Relicense wg(8) as MIT and integrate into upstream build system. +- Examine possibility of a non-bash wg-quick(8) for sending upstream. -- cgit v1.2.3-59-g8ed1b
