Josh Bleecher Snyder	e0bd3cc70c	wgengine/magicsock: use netaddr.MustParseIPPrefix Delete our bespoke helper. Signed-off-by: Josh Bleecher Snyder <josh@tailscale.com>	4 years ago
Josh Bleecher Snyder	bc68e22c5b	all: s/CreateEndpoint/ParseEndpoint/ in docs Upstream wireguard-go renamed the interface method from CreateEndpoint to ParseEndpoint. I missed some comments. Fix them. Signed-off-by: Josh Bleecher Snyder <josh@tailscale.com>	4 years ago
Josh Bleecher Snyder	9bce1b7fc1	wgengine/wgcfg: make device test endpoint-format-agnostic By using conn.NewDefaultBind, this test requires that our endpoints be comprehensible to wireguard-go. Instead, use a no-op bind that treats endpoints as opaque strings. Signed-off-by: Josh Bleecher Snyder <josh@tailscale.com>	4 years ago
Josh Bleecher Snyder	73ad1f804b	wgengine/wgcfg: use autogenerated Clone methods Delete the manually written ones named Copy. Signed-off-by: Josh Bleecher Snyder <josh@tailscale.com>	4 years ago
Josh Bleecher Snyder	05bed64772	types/wgkey: simplify Key.UnmarshalJSON Instead of calling ParseHex, do the hex.Decode directly. name old time/op new time/op delta UnmarshalJSON-8 86.9ns ± 0% 42.6ns ± 0% -50.94% (p=0.000 n=15+14) name old alloc/op new alloc/op delta UnmarshalJSON-8 128B ± 0% 0B -100.00% (p=0.000 n=15+15) name old allocs/op new allocs/op delta UnmarshalJSON-8 2.00 ± 0% 0.00 -100.00% (p=0.000 n=15+15) Signed-off-by: Josh Bleecher Snyder <josh@tailscale.com>	4 years ago
Josh Bleecher Snyder	a0dacba877	wgengine/magicsock: simplify legacy endpoint DstToString Legacy endpoints (addrSet) currently reconstruct their dst string when requested. Instead, store the dst string we were given to begin with. In addition to being simpler and cheaper, this makes less code aware of how to interpret endpoint strings.

Josh Bleecher Snyder	777c816b34	wgengine/wgcfg: return better errors from DeviceConfig, ReconfigDevice Prefer the error from the actual wireguard-go device method call, not {To,From}UAPI, as those tend to be less interesting I/O errors. Signed-off-by: Josh Bleecher Snyder <josh@tailscale.com>	4 years ago
Josh Bleecher Snyder	1f6c4ba7c3	wgengine/wgcfg: prevent ReconfigDevice from hanging on error When wireguard-go's UAPI interface fails with an error, ReconfigDevice hangs. Fix that by buffering the channel and closing the writer after the call. The code now matches the corresponding code in DeviceConfig, where I got it right. Signed-off-by: Josh Bleecher Snyder <josh@tailscale.com>	4 years ago
Josh Bleecher Snyder	462f7e38fc	tailcfg: fix typo in comment Signed-off-by: Josh Bleecher Snyder <josh@tailscale.com>	4 years ago
Josh Bleecher Snyder	ed63a041bf	wgengine/userspace: delete HandshakeDone It is unused, and has been since early Feb 2021 (Tailscale 1.6). We can't get delete the DeviceOptions entirely yet; first #1831 and #1839 need to go in, along with some wireguard-go changes. Deleting this chunk of code now will make the later commits more clearly correct. Pingers can now go too. Signed-off-by: Josh Bleecher Snyder <josh@tailscale.com>	4 years ago

Brad Fitzpatrick	b8fb8264a5	wgengine/netstack: avoid delivering incoming packets to both netstack + host The earlier `eb06ec172f` fixed the flaky SSH issue (tailscale/corp#1725) by making sure that packets addressed to Tailscale IPs in hybrid netstack mode weren't delivered to netstack, but another issue remained: All traffic handled by netstack was also potentially being handled by the host networking stack, as the filter hook returned "Accept", which made it keep processing. This could lead to various random racey chaos as a function of OS/firewalls/routes/etc. Instead, once we inject into netstack, stop our caller's packet processing.

Brad Fitzpatrick	7f2eb1d87a	net/tstun: fix TUN log spam when ACLs drop a packet Whenever we dropped a packet due to ACLs, wireguard-go was logging: Failed to write packet to TUN device: packet dropped by filter Instead, just lie to wireguard-go and pretend everything is okay.

Josh Bleecher Snyder	f116a4c44f	types/logger: fix rate limiter allowlist Upstream wireguard-go renamed the interface method from CreateEndpoint to ParseEndpoint. I updated the log call site but not the allowlist. Signed-off-by: Josh Bleecher Snyder <josharian@gmail.com>	4 years ago
Josh Bleecher Snyder	be56aa4962	workflows: execute benchmarks #1817 removed the only place in our CI where we executed our benchmark code. Fix that by executing it everywhere. The benchmarks are generally cheap and fast, so this should add minimal overhead. Signed-off-by: Josh Bleecher Snyder <josharian@gmail.com>	4 years ago

Josh Bleecher Snyder	ac75958d2e	workflows: run staticcheck on more platforms To prevent issues like #1786, run staticcheck on the primary GOOSes: linux, mac, and windows. Windows also has a fair amount of GOARCH-specific code. If we ever have GOARCH staticcheck failures on other GOOSes, we can expand the test matrix further. This requires installing the staticcheck binary so that we can execute it with different GOOSes. Signed-off-by: Josh Bleecher Snyder <josharian@gmail.com>	4 years ago
Avery Pennarun	6d10655dc3	ipnlocal: accept a new opts.UpdatePrefs field. This is needed because the original opts.Prefs field was at some point subverted for use in frontend->backend state migration for backward compatibility on some platforms. We still need that feature, but we also need the feature of providing the full set of prefs from `tailscale up`, not including overwriting the prefs.Persist keys, so we can't use the original field from `tailscale up`. `tailscale up` had attempted to compensate for that by doing SetPrefs() before Start(), but that violates the ipn.Backend contract, which says you should call Start() before anything else (that's why it's called Start()). As a result, doing SetPrefs({ControlURL=..., WantRunning=true}) would cause a connection to the previous control server (because WantRunning=true), and then connect to the new control server only after running Start(). This problem may have been avoided before, but only by pure luck. It turned out to be relatively harmless since the connection to the old control server was immediately closed and replaced anyway, but it created a race condition that could have caused spurious notifications or rejected keys if the server responded quickly. As already covered by existing TODOs, a better fix would be to have Start() get out of the business of state migration altogether. But we're approaching a release so I want to make the minimum possible fix. Fixes #1840. Signed-off-by: Avery Pennarun <apenwarr@tailscale.com>	4 years ago
Josh Bleecher Snyder	7dbbe0c7c7	cmd/tailscale/cli: fix running from Xcode We were over-eager in running tailscale in GUI mode. `f42ded7acf` fixed that by checking for a variety of shell-ish env vars and using those to force us into CLI mode. However, for reasons I don't understand, those shell env vars are present when Xcode runs Tailscale.app on my machine. (I've changed no configs, modified nothing on a brand new machine.) Work around that by adding an additional "only in GUI mode" check. Signed-off-by: Josh Bleecher Snyder <josharian@gmail.com>	4 years ago

Brad Fitzpatrick	962bf74875	cmd/tailscale: fail if tailscaled closes the IPN connection I was going to write a test for this using the tstest/integration test stuff, but the testcontrol implementation isn't quite there yet (it always registers nodes and doesn't provide AuthURLs).

Josh Bleecher Snyder	96ef8d34ef	ipn/ipnlocal: switch from testify to quicktest Per discussion, we want to have only one test assertion library, and we want to start by exploring quicktest. This was a mostly mechanical translation. I think we could make this nicer by defining a few helper closures at the beginning of the test. Later.

Brad Fitzpatrick	90002be6c0	cmd/tailscale: make pref-revert checks ignore OS-irrelevant prefs This fixes #1833 in two ways: * stop setting NoSNAT on non-Linux. It only matters on Linux and the flag is hidden on non-Linux, but the code was still setting it. Because of that, the new pref-reverting safety checks were failing when it was changing. * Ignore the two Linux-only prefs changing on non-Linux.

Josh Bleecher Snyder	59026a291d	wgengine/wglog: improve wireguard-go logging rate limiting Prior to wireguard-go using printf-style logging, all wireguard-go logging occurred using format string "%s". We fixed that but continued to use %s when we rewrote peer identifiers into Tailscale style. This commit removes that %sl, which makes rate limiting work correctly. As a happy side-benefit, it should generate less garbage. Instead of replacing all wireguard-go peer identifiers that might occur anywhere in a fully formatted log string, assume that they only come from args. Check all args for things that look like *device.Peers and replace them with appropriately reformatted strings. There is a variety of ways that this could go wrong (unusual format verbs or modifiers, peer identifiers occurring as part of a larger printed object, future API changes), but none of them occur now, are likely to be added, or would be hard to work around if they did.
