James Tucker	e1c7e9b736	wgengine/magicsock: improve endpoint selection for WireGuard peers with rx time ... If we don't have the ICMP hint available, such as on Android, we can use the signal of rx traffic to bias toward a particular endpoint. We don't want to stick to a particular endpoint for a very long time without any signals, so the sticky time is reduced to 1 second, which is large enough to avoid excessive packet reordering in the common case, but should be small enough that either rx provides a strong signal, or we rotate in a user-interactive schedule to another endpoint, improving the feel of failover to other endpoints.

James Tucker	5edb39d032	wgengine/magicsock: clear out endpoint statistics when it becomes bad ... There are cases where we do not detect the non-viability of a route, but we will instead observe a failure to send. In a Disco path this would normally be handled as a side effect of Disco, which is not available to non-Disco WireGuard nodes. In both cases, recognizing the failure as such will result in faster convergence. Updates #8999 Signed-off-by: James Tucker <james@tailscale.com>	1 year ago
Charlotte Brandhorst-Satzkorn	7c9c68feed	wgengine/magicsock: update lastfullping comment to include wg only ... LastFullPing is now used for disco or wireguard only endpoints. This change updates the comment to make that clear. Updates #7826 Signed-off-by: Charlotte Brandhorst-Satzkorn <charlotte@tailscale.com>	1 year ago
James Tucker	3a652d7761	wgengine/magicsock: clear endpoint state in noteConnectivityChange ... There are latency values stored in bestAddr and endpointState that are no longer applicable after a connectivity change and should be cleared out, following the documented behavior of the function.

Val	c15997511d	wgengine/magicsock: only accept pong sent by CLI ping ... When sending a ping from the CLI, only accept a pong that is in reply to the specific CLI ping we sent. Updates #311 Signed-off-by: Val <valerie@tailscale.com>	1 year ago

salman aljammaz	25a7204bb4	wgengine,ipn,cmd/tailscale: add size option to ping (#8739) ... This adds the capability to pad disco ping message payloads to reach a specified size. It also plumbs it through to the tailscale ping -size flag. Disco pings used for actual endpoint discovery do not use this yet. Updates #311.
