Brad Fitzpatrick	9ce92aad3e	cmd/tailscaled: update depaware.txt	4 years ago
Brad Fitzpatrick	fa3543d629	control/controlclient: use more direct way of getting the MagicDNS suffix Suggested by Avery earlier. Ends up fixing bug in "tailscale status" when MagicDNS if off too: https://forum.tailscale.com/t/1-3-293-is-released-a-1-4-0-pre-release/349/11?u=bradfitz	4 years ago
Brad Fitzpatrick	e7bf144c3f	ipn, wgengine/filter: fix Shields Up recent regression and old bug Fixes #1192 (regression) Fixes #1193 (old bug)	4 years ago
Brad Fitzpatrick	97496a83af	wgengine/tstun: also support DropSilently on PostFilterIn Not a problem (yet). But should be consistent with other places that support both types of drops.	4 years ago
Brad Fitzpatrick	eb47cba435	cmd/tailscaled: don't require --state for --cleanup	4 years ago
Brad Fitzpatrick	daf2c70a08	go.mod: bump wireguard-go	4 years ago
Josh Bleecher Snyder	d5baeeed5c	wgengine: use Tailscale-style peer identifiers in logs Rewrite log lines on the fly, based on the set of known peers. This enables us to use upstream wireguard-go logging, but maintain the Tailscale-style peer public key identifiers that the rest of our systems (and people) expect. Fixes #1183 Signed-off-by: Josh Bleecher Snyder <josh@tailscale.com>	4 years ago
Brad Fitzpatrick	4306433d1c	cmd/tailscale: make "tailscale ping" also resolve names without DNS This lets "tailscale ping $NAME" work even if MagicDNS is off, letting you ping a name that shows up in "tailscale status". More user friendly.	4 years ago
Brad Fitzpatrick	9541886856	wgengine/magicsock: disable regular STUNs for all platforms by default Reduces background CPU & network. Updates #1034 Signed-off-by: Brad Fitzpatrick <bradfitz@tailscale.com>	4 years ago
David Anderson	49d00b6a28	tailcfg: add StableID to Node. #1178 Signed-off-by: David Anderson <danderson@tailscale.com>	4 years ago
Brad Fitzpatrick	54d0d83b67	safesocket: on Linux, make /var/run/tailscale be 0755 Continuation of earlier two umask changes, `5611f290eb` and `d6e9fb1df0`. This change mostly affects us, running tailscaled as root by hand (wit a umask of 0077), not under systemd. End users running tailscaled under systemd won't have a umask.

Steve Coffman	fec9490378	Add docker build script to inject version information Signed-off-by: Steve Coffman <steve@khanacademy.org>	4 years ago
Brad Fitzpatrick	c55d26967b	wgengine/magicsock: log more details of endpoints learned over disco Also, don't try to use IPv6 LinkLocalUnicast addresses for now. Like endpoints exchanged with control, we share them but don't yet use them. Updates #1172	4 years ago
Brad Fitzpatrick	9f1b02699a	tstime: add RandomDurationBetween helper Signed-off-by: Brad Fitzpatrick <bradfitz@tailscale.com>	4 years ago
Brad Fitzpatrick	a905ce5607	control/controlclient: add debug knob to not use control's endpoints	4 years ago
Brad Fitzpatrick	359055d3fa	wgengine/magicsock: fix logging regression `c8c493f3d9` made it always say `created=false` which scared me when I saw it, as that would've implied things were broken much worse. Fortunately the logging was just wrong.	4 years ago
Brad Fitzpatrick	b5628cee4e	control/controlclient: add detail to verbose log about route skips	4 years ago
Brad Fitzpatrick	edf64e0901	wgengine/magicsock: send, use endpoints in CallMeMaybe messages Fixes #1172 Signed-off-by: Brad Fitzpatrick <bradfitz@tailscale.com>	4 years ago
Brad Fitzpatrick	ec77b80c53	tailcfg, control/controlclient: add mapver 10: MapResponse.PeerSeenChange This adds a more wire-efficient way of updating peers' Node.LastSeen times. Signed-off-by: Brad Fitzpatrick <bradfitz@tailscale.com>	4 years ago
Brad Fitzpatrick	b5b4992eff	disco: support parsing/encoding endpoints in call-me-maybe frames Updates #1172 Signed-off-by: Brad Fitzpatrick <bradfitz@tailscale.com>	4 years ago
Josh Bleecher Snyder	d3dd7c6270	wgengine/magicsock: make legacy DstToString match Addrs DstToString is used in two places in wireguard-go: Logging and uapi. We are switching to use uapi for wireguard-go config. To preserve existing behavior, we need the full set of addrs. And for logging, having the full set of addrs seems useful. (The Addrs method itself is slated for removal. When that happens, the implementation will move to DstToString.) Signed-off-by: Josh Bleecher Snyder <josh@tailscale.com>	4 years ago
Brad Fitzpatrick	187e22a756	wgengine/magicsock: don't run the DERP cleanup so often To save CPU and wakeups, don't run the DERP cleanup timer regularly unless there is a non-home DERP connection open. Also eliminates the goroutine, moving to a time.AfterFunc. Updates #1034 Signed-off-by: Brad Fitzpatrick <bradfitz@tailscale.com>	4 years ago
David Anderson	ab9cccb292	cmd/tailscale/cli: require v4 and v6 default routes to be advertised together. Signed-off-by: David Anderson <danderson@tailscale.com>	4 years ago

Josh Bleecher Snyder	5fe5402fcd	Revert "wgengine/magicsock: shortcircuit discoEndpoint.heartbeat when its connection is closed" This reverts commit `08baa17d9a`. It caused deadlocks due to lock ordering violations. It was not the right fix, and thus should simply be reverted while we look for the right fix (if we haven't already found it in the interim; we've fixed other logging-after-test issues). Fixes #1161	4 years ago
Josh Bleecher Snyder	e4c075cd95	wgengine/magicsock: prevent log-after-test in TestTwoDevicePing	4 years ago
Brad Fitzpatrick	edce91a8a6	wgengine/magicsock: fix a naked return bug/crash where we returned (nil, true) The 'ok' from 'ipp, ok :=' above was the result parameter ok. Whoops.	4 years ago
Brad Fitzpatrick	51bd1feae4	wgengine/magicsock: add single element IPPort->endpoint cache in receive path name old time/op new time/op delta ReceiveFrom-4 21.8µs ± 2% 20.9µs ± 2% -4.27% (p=0.000 n=10+10) Updates #414 Signed-off-by: Brad Fitzpatrick <bradfitz@tailscale.com>	4 years ago
David Anderson	da4ec54756	tailcfg: remove v6-overlay debug option. It's about to become a no-op in control. Signed-off-by: David Anderson <danderson@tailscale.com>	4 years ago

Brad Fitzpatrick	3fa86a8b23	wgengine/magicsock: use relatively new netaddr.IPPort.IsZero method	4 years ago
Brad Fitzpatrick	4811236189	wgengine/magicsock: speed up BenchmarkReceiveFrom, store context.Done chan context.cancelCtx.Done involves a mutex and isn't as cheap as I previously assumed. Convert the donec method into a struct field and store the channel value once. Our one magicsock.Conn gets one pointer larger, but it cuts ~1% of the CPU time of the ReceiveFrom benchmark and removes a bubble from the --svg output :)	4 years ago
Brad Fitzpatrick	c78ed5b399	go.sum: update (forgotten after earlier wireguard-go update again)	4 years ago
Denton Gentry	013da6660e	logtail: add tests + add a test for parseAndRemoveLogLevel() + add a test for drainPendingMessages() + test JSON log encoding including several special cases Other tests frequently send logs but a) don't check the result and b) do so by happenstance, such that the code in encode() was not consistently being exercised and leading to spurious changes in code coverage. These tests attempt to more systematically test the logging function. This is the second attempt to add these tests, the first attempt (in https://github.com/tailscale/tailscale/pull/1114) had two issues: 1. httptest.NewServer creates multiple goroutine handlers, and logtail uses goroutines to upload, but the first version had no locking in the server to guard this. Moved data handling into channels to get synchronization. 2. The channel to notify the test of the arrival of data had a depth of 1, in cases where the Logger sent multiple uploads it would block the server. This resulted in the first iteration of these tests being flaky, and we reverted it. This new version of the tests has passed with go test -race -count=10000 and seems solid.

Denton Gentry	8578b0445d	tstun: add test to send a packet after Close() This test serves two purposes: + check that Write() returns an error if the tstun has been closed. + ensure that the close-related code in tstun is exercised in a test case. We were getting spurious code coverage adds/drops based on timing of when the test case finished. Signed-off-by: Denton Gentry <dgentry@tailscale.com>	4 years ago
Josh Bleecher Snyder	7c1a9e8616	net/nettest: de-flake tests on Windows Windows has a low resolution timer. Some of the tests assumed that unblock takes effect immediately. Consider: t := time.Now() elapsed := time.Now().After(t) It seems plausible that elapsed should always be true. However, with a low resolution timer, that might fail. Change time.Now().After to !time.Now().Before, so that unblocking always takes effect immediately. Fixes #873.	4 years ago
Josh Bleecher Snyder	a64d06f15c	net/nettest: remove pointless checks in tests If err == nil, then !errors.Is(err, anything).	4 years ago
Josh Bleecher Snyder	503db5540f	net/nettest: add missing check at end of TestLimit This appears to have been an oversight.	4 years ago

Josh Bleecher Snyder	63af950d8c	wgengine/magicsock: adapt to wireguard-go without UpdateDst `22507adf54` stopped relying on our fork of wireguard-go's UpdateDst callback. As a result, we can unwind that code, and the extra return value of ReceiveIPv{4,6}. Signed-off-by: Josh Bleecher Snyder <josh@tailscale.com>	4 years ago
Denton Gentry	23c2dc2165	magicksock: remove TestConnClosing. (#1140 ) Test is flakey, remove it and figure out what to do differently later. Signed-off-by: Denton Gentry <dgentry@tailscale.com>	4 years ago
David Anderson	e23b4191c4	wgengine/magicsock: disable legacy networking everywhere except TwoDevicePing. TwoDevicePing is explicitly testing the behavior of the legacy codepath, everything else is happy to assume that code no longer exists. Signed-off-by: David Anderson <danderson@tailscale.com>	4 years ago
David Anderson	0733c5d2e0	wgengine/magicsock: disable legacy behavior in a few more tests. Signed-off-by: David Anderson <danderson@tailscale.com>	4 years ago

David Anderson	a2463e8948	wgengine/magicsock: add an option to disable legacy peer handling. Used in tests to ensure we're not relying on behavior we're going to remove eventually. Signed-off-by: David Anderson <danderson@tailscale.com>	4 years ago
David Anderson	d456bfdc6d	wgengine/magicsock: fix BenchmarkReceiveFrom. Previously, this benchmark relied on behavior of the legacy receive codepath, which I changed in `22507adf`. With this change, the benchmark instead relies on the new active discovery path. Signed-off-by: David Anderson <danderson@tailscale.com>	4 years ago
