Jordan Whited	7aec8d4e6b	cmd/stunstamp: refactor connection construction (#13110) ... getConns() is now responsible for returning both stable and unstable conns. conn and measureFn are now passed together via connAndMeasureFn. newConnAndMeasureFn() is responsible for constructing them. TCP measurement timeouts are adjusted to more closely match netcheck. Updates tailscale/corp#22114 Signed-off-by: Jordan Whited <jordan@tailscale.com>	3 months ago
Jordan Whited	218110963d	cmd/stunstamp: implement HTTPS & TCP latency measurements (#13082) ... HTTPS mirrors current netcheck behavior and TCP uses tcp_info->rtt. Updates tailscale/corp#22114 Signed-off-by: Jordan Whited <jordan@tailscale.com>	3 months ago
Jordan Whited	20691894f5	cmd/stunstamp: refactor to support multiple protocols (#13063) ... 'stun' has been removed from metric names and replaced with a protocol label. This refactor is preparation work for HTTPS & ICMP support. Updates tailscale/corp#22114 Signed-off-by: Jordan Whited <jordan@tailscale.com>	3 months ago
Jordan Whited	ddf94a7b39	cmd/stunstamp: fix handling of invalid DERP map resp (#12679) ... Updates tailscale/corp#20344 Signed-off-by: Jordan Whited <jordan@tailscale.com>	5 months ago
Jordan Whited	94415e8029	cmd/stunstamp: remove sqlite DB and API (#12604) ... stunstamp now sends data to Prometheus via remote write, and Prometheus can serve the same data. Retaining and cleaning up old data in sqlite leads to long probing pauses, and it's not worth investing more effort to optimize the schema and/or concurrency model.

Jordan Whited	0d6e71df70	cmd/stunstamp: add explicit metric to track timeout events (#12564) ... Timeouts could already be identified as NaN values on stunstamp_derp_stun_rtt_ns, but we can't use NaN effectively with promql to visualize them. So, this commit adds a timeouts metric that we can use with rate/delta/etc promql functions. Updates tailscale/corp#20689 Signed-off-by: Jordan Whited <jordan@tailscale.com>	5 months ago
Jordan Whited	6e106712f6	cmd/stunstamp: support probing multiple ports (#12356) ... Updates tailscale/corp#20344 Signed-off-by: Jordan Whited <jordan@tailscale.com>	5 months ago
Maisem Ali	4a8cb1d9f3	all: use math/rand/v2 more ... Updates #11058 Signed-off-by: Maisem Ali <maisem@tailscale.com>	5 months ago
Jordan Whited	cf1e6c6e55	cmd/stunstamp: fix remote write retry (#12348) ... Evaluation of remote write errors was using errors.Is() where it should have been using errors.As(). Updates tailscale/corp#20344 Signed-off-by: Jordan Whited <jordan@tailscale.com>	5 months ago
Jordan Whited	ba0dd493c8	cmd/stunstamp: validate STUN tx ID in responses (#12339) ... Extremely late arriving responses may leak across probing intervals. Updates tailscale/corp#20344 Signed-off-by: Jordan Whited <jordan@tailscale.com>	5 months ago
Jordan Whited	d21c00205d	cmd/stunstamp: implement service to measure DERP STUN RTT (#12241) ... stunstamp timestamping includes userspace and SO_TIMESTAMPING kernel timestamping where available. Measurements are written locally to a sqlite DB, exposed over an HTTP API, and written to prometheus via remote-write protocol.
