David Anderson	463b3e8f62	net/dnscache: use tls.Conn.HandshakeContext. Go 1.17 added a HandshakeContext func to take care of timeouts during TLS handshaking, so switch from our homegrown goroutine implementation to the standard way. Signed-off-by: David Anderson <danderson@tailscale.com>	3 years ago
David Anderson	a9da6b73a8	net/dnscache: don't cancel the TLS context before writing to the result channel. Cancelling the context makes the timeout goroutine race with the write that reports a successful TLS handshake, so you can end up with a successful TLS handshake that mysteriously reports that it timed out after ~0s in flight. The context is always canceled and cleaned up as the function exits, which happens mere microseconds later, so just let function exit clean up and thereby avoid races.

Josh Bleecher Snyder	a076aaecc6	cmd/tailscale: use html/template for synoTokenRedirect The GitHub code scanner flagged this as a security vulnerability. I don't believe it was, but I couldn't convince myself of it 100%. Err on the safe side and use html/template to generate the HTML, with all necessary escaping.

Brad Fitzpatrick	e6626366a2	cmd/tailscale: let 'tailscale up --reset' do a pref edit The --reset shouldn't imply that a Backend.Start is necessary. With this, it can do a Backend.EditPrefs instead, which then doesn't do all the heavy work that Start does. Also, Start on Windows behaves slightly differently than Linux etc in some cases because of tailscaled running in client mode on Windows (where the GUI supplies the prefs).

Brad Fitzpatrick	28bf53f502	wgengine/magicsock: reduce disco ping heartbeat aggressiveness a bit Bigger changes coming later, but this should improve things a bit in the meantime. Rationale: * 2 minutes -> 45 seconds: 2 minutes was overkill and never considered phones/battery at the time. It was totally arbitrary. 45 seconds is also arbitrary but is less than 2 minutes. * heartbeat from 2 seconds to 3 seconds: in practice this meant two packets per second (2 pings and 2 pongs every 2 seconds) because the other side was also pinging us every 2 seconds on their own. That's just overkill. (see #540 too) So in the worst case before: when we sent a single packet (say: a DNS packet), we ended up sending 61 packets over 2 minutes: the 1 DNS query and then then 60 disco pings (2 minutes / 2 seconds) & received the same (1 DNS response + 60 pongs). Now it's 15. In 1.22 we plan to remove this whole timer-based heartbeat mechanism entirely. The 5 seconds to 6.5 seconds change is just stretching out that interval so you can still miss two heartbeats (other 3 + 3 seconds would be greater than 5 seconds). This means that if your peer moves without telling you, you can have a path out for 6.5 seconds now instead of 5 seconds before disco finds a new one. That will also improve in 1.22 when we start doing UDP+DERP at the same time when confidence starts to go down on a UDP path.
