Brad Fitzpatrick	02bdc654d5	cmd/tailscale: fix up --reset, again Also fix a somewhat related printing bug in the process where some paths would print "Success." inconsistently even when there otherwise was no output (in the EditPrefs path) Fixes #3830 Updates #3702 (which broke it once while trying to fix it) Change-Id: Ic51e14526ad75be61ba00084670aa6a98221daa5 Signed-off-by: Brad Fitzpatrick <bradfitz@tailscale.com>	2 years ago

Brad Fitzpatrick	1af26222b6	go.mod: bump netstack, switch to upstream netstack Now that Go 1.17 has module graph pruning (https://go.dev/doc/go1.17#go-command), we should be able to use upstream netstack without breaking our private repo's build that then depends on the tailscale.com Go module. This is that experiment. Updates #1518 (the original bug to break out netstack to own module) Updates #2642 (this updates netstack, but doesn't remove workaround) Change-Id: I27a252c74a517053462e5250db09f379de8ac8ff Signed-off-by: Brad Fitzpatrick <bradfitz@tailscale.com>	2 years ago

David Anderson	7a18fe3dca	wgengine/magicsock: make debugUseDerpRoute an opt.Bool. Can still be constant, just needs the extra methods. Fixes #3812 Signed-off-by: David Anderson <danderson@tailscale.com>	2 years ago
David Anderson	c2059d5b8a	words: fallout from mudpuppy-gate. Salamanders also have no scales. I checked the interweb, and there doesn't seem to be any subspecies that would let us claim that some salamanders are scaley. But they are tailey, for sure.

Brad Fitzpatrick	ca774c3249	ipn/ipnserver: add TS_PERMIT_CERT_UID envknob to give webservers cert access So you can run Caddy etc as a non-root user and let it have access to get certs. Updates caddyserver/caddy#4541 Change-Id: Iecc5922274530e2b00ba107d4b536580f374109b Signed-off-by: Brad Fitzpatrick <bradfitz@tailscale.com>	2 years ago

davideger	f31546809f	cmd/tailscale: propagate tailscaled 403s as AccessDeniedErrors So Linux/etc CLI users get helpful advice to run tailscale with --operator=$USER when they try to 'tailscale file {cp,get}' but are mysteriously forbidden.

Brad Fitzpatrick	f3c0023add	wgengine/netstack: add an SSH server experiment Disabled by default. To use, run tailscaled with: TS_SSH_ALLOW_LOGIN=you@bar.com And enable with: $ TAILSCALE_USE_WIP_CODE=true tailscale up --ssh=true Then ssh [any-user]@[your-tailscale-ip] for a root bash shell. (both the "root" and "bash" part are temporary) Updates #3802 Change-Id: I268f8c3c95c8eed5f3231d712a5dc89615a406f0 Signed-off-by: Brad Fitzpatrick <bradfitz@tailscale.com>	2 years ago
Brad Fitzpatrick	41fd4eab5c	envknob: add new package for all the strconv.ParseBool(os.Getenv(..)) A new package can also later record/report which knobs are checked and set. It also makes the code cleaner & easier to grep for env knobs. Change-Id: Id8a123ab7539f1fadbd27e0cbeac79c2e4f09751 Signed-off-by: Brad Fitzpatrick <bradfitz@tailscale.com>	2 years ago

David Anderson	7ba874d7f1	words: correct inexcusable oversight re: mudpuppies. Mudpuppies are salamanders, and as such have tails but no scales. The management apologizes for the error. Signed-off-by: David Anderson <danderson@tailscale.com>	2 years ago
Brad Fitzpatrick	92dfaf53bb	cmd/tailscaled: include Go runtime metrics in /debug/metrics Fixes #3772 Change-Id: I237ea23268664d99e83d27890146018b04474556 Signed-off-by: Brad Fitzpatrick <bradfitz@tailscale.com>	2 years ago
Aaron Bieber	411c6c316c	net/dns/resolvd: store nameservers Currently only search domains are stored. This was an oversight (under?) on my part. As things are now, when MagicDNS is on and "Override local DNS" is off, the dns forwarder has to timeout before names resolve. This introduces a pretty annoying lang that makes everything feel extremely slow. You will also see an error: "upstream nameservers not set". I tested with "Override local DNS" on and off. In both situations things seem to function as expected (and quickly). Signed-off-by: Aaron Bieber <aaron@bolddaemon.com>	2 years ago
Brad Fitzpatrick	c64af5e676	wgengine/netstack: clear TCP ECN bits before giving to gvisor Updates #2642 Change-Id: Ic219442a2656dd9dc99ae1dd91e907fd3d924987 Signed-off-by: Brad Fitzpatrick <bradfitz@tailscale.com>	2 years ago
Josh Bleecher Snyder	de4696da10	wgengine/magicsock: fix deadlock on shutdown This fixes a deadlock on shutdown. One goroutine is waiting to send on c.derpRecvCh before unlocking c.mu. The other goroutine is waiting to lock c.mu before receiving from c.derpRecvCh. #3736 has a more detailed explanation of the sequence of events.

Brad Fitzpatrick	6be48dfcc6	wgengine/netstack: fix netstack ping timeout on darwin -W is milliseconds on darwin, not seconds, and empirically it's milliseconds after a 1 second base.

David Anderson	96f008cf87	control/controlhttp: package to get a controlbase.Conn over HTTP(S). Updates #3488 Signed-off-by: David Anderson <danderson@tailscale.com>	2 years ago
David Anderson	d5a7eabcd0	control/controlbase: enable asynchronous client handshaking. With this change, the client can obtain the initial handshake message separately from the rest of the handshake, for embedding into another protocol. This enables things like RTT reduction by stuffing the handshake initiation message into an HTTP header. Similarly, the server API optionally accepts a pre-read Noise initiation message, in addition to reading the message directly off a net.Conn.

Josh Bleecher Snyder	8cf1af8a07	tstime/rate: deflake TestLongRunningQPS This test set the bar too high. Just a couple of missed timers was enough to fail. Change the test to more of a sanity check. While we're here, run it for just 1s instead of 5s. Prior to this change, on a 13" M1 MPB, with stress -p 512 ./rate.test -test.run=QPS I saw 90%+ failures. After this change, I'm at 30k runs with no failures yet. Fixes #3733 Signed-off-by: Josh Bleecher Snyder <josh@tailscale.com>	2 years ago
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>	2 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	9fe5ece833	logtail: cap the buffer size in encodeText This started as an attempt to placate GitHub's code scanner, but it's also probably generally a good idea. Signed-off-by: Josh Bleecher Snyder <josh@tailscale.com>	2 years ago

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	24a04d07d1	net/dns/resolver: handle tabs as whitespace when ExitDNS parses resolv.conf On Synology, the /etc/resolv.conf has tabs in it, which this resolv.conf parser (we have two, sigh) didn't handle.

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).
