James Tucker	672c2c8de8	wgengine/magicsock: add filter to ignore disco to old/other ports Incoming disco packets are now dropped unless they match one of the current bound ports, or have a zero port. The BPF filter passes all packets with a disco header to the raw packet sockets regardless of destination port (in order to avoid needing to reconfigure BPF on rebind). If a BPF enabled node has just rebound, due to restart or rebind, it may receive and reply to disco ping packets destined for ports other than those which are presently bound. If the pong is accepted, the pinging node will now assume that it can send WireGuard traffic to the pinged port - such traffic will not reach the node as it is not destined for a bound port. The zero port is ignored, if received. This is a speculative defense and would indicate a problem in the receive path, or the BPF filter. This condition is allowed to pass as it may enable traffic to flow, however it will also enable problems with the same symptoms this patch otherwise fixes.

James Tucker	be140add75	wgengine/magicsock: fix regression in initial bind for js `1f959edeb0` introduced a regression for JS where the initial bind no longer occurred at all for JS. The condition is moved deeper in the call tree to avoid proliferation of higher level conditions. Updates #5537 Signed-off-by: James Tucker <james@tailscale.com>	2 years ago
James Tucker	1f959edeb0	wgengine/magicksock: remove nullability of RebindingUDPConns Both RebindingUDPConns now always exist. the initial bind (which now just calls rebind) now ensures that bind is called for both, such that they both at least contain a blockForeverConn. Calling code no longer needs to assert their state. Signed-off-by: James Tucker <james@tailscale.com>	2 years ago

Andrew Dunham	f52a659076	net/dnsfallback: allow setting log function (#5550 ) This broke a test in corp that enforces we don't use the log package. Signed-off-by: Andrew Dunham <andrew@tailscale.com>	2 years ago
Andrew Dunham	b8596f2a2f	net/dnsfallback: cache most recent DERP map on disk (#5545 ) This is especially helpful as we launch newer DERPs over time, and older clients have progressively out-of-date static DERP maps baked in. After this, as long as the client has successfully connected once, it'll cache the most recent DERP map it knows about.

Maisem Ali	060ecb010f	docs/k8s: make run.sh handle SIGINT It was previously using jobcontrol to achieve this, but that apparently doesn't work when there is no tty. This makes it so that it directly handles SIGINT and SIGTERM and passes it on to tailscaled. I tested this works on a Digital Ocean K8s cluster.

Will Norris	3344c3b89b	tsnet: add Server method to listener Allow callers to verify that a net.Listener is a tsnet.listener by type asserting against this Server method, as well as providing access to the underlying Server.

Xe Iaso	3564fd61b5	cmd/gitops-pusher: standardize hujson before posting to validate (#5525 ) Apparently the validate route doesn't check content-types or handle hujson with comments correctly.

nyghtowl	cfbbcf6d07	cmd/nginx-auth/nginx-auth: update auth to allow for new domains With MagicDNS GA, we are giving every tailnet a tailnet-<hex>.ts.net name.

Joe Tsai	7e40071571	util/deephash: handle slice edge-cases (#5471 ) It is unclear whether the lack of checking nil-ness of slices was an oversight or a deliberate feature. Lacking a comment, the assumption is that this was an oversight. Also, expand the logic to perform cycle detection for recursive slices. We do this on a per-element basis since a slice is semantically equivalent to a list of pointers. Signed-off-by: Joe Tsai <joetsai@digital-static.net>	2 years ago

Andrew Dunham	d6c3588ed3	wgengine/wgcfg: only write peer headers if necessary (#5449 ) On sufficiently large tailnets, even writing the peer header (~95 bytes) can result in a large amount of data that needs to be serialized and deserialized.
