Avery Pennarun	65fbb9c303	wgengine/filter: support subnet mask rules, not just /32 IPs. ... This depends on improved support from the control server, to send the new subnet width (Bits) fields. If these are missing, we fall back to assuming their value is /32. Conversely, if the server sends Bits fields to an older client, it will interpret them as /32 addresses. Since the only rules we allow are "accept" rules, this will be narrower or equal to the intended rule, so older clients will simply reject hosts on the wider subnet (fail closed). With this change, the internal filter.Matches format has diverged from the wire format used by controlclient, so move the wire format into tailcfg and convert it to filter.Matches in controlclient.

Avery Pennarun	85e675940d	wgengine/filter: allow ICMP response packets. ... Longer term, we should probably update the packet filter to be fully stateful, for both TCP and ICMP. That is, only ICMP packets related to a session *we* initiated should be allowed back in. But this is reasonably secure for now, since wireguard is already trimming most traffic. The current code would not protect against eg. Ping-of-Death style attacks from VPN nodes. Fixes tailscale/tailscale#290. Signed-off-by: Avery Pennarun <apenwarr@tailscale.com>	5 years ago
