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	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

David Anderson	d456bfdc6d	wgengine/magicsock: fix BenchmarkReceiveFrom. Previously, this benchmark relied on behavior of the legacy receive codepath, which I changed in `22507adf`.

Brad Fitzpatrick	b560386c1a	net/packet, wgengine, tstun: add inter-node TSMP protocol for connect errors This adds a new IP Protocol type, TSMP on protocol number 99 for sending inter-tailscale messages over WireGuard, currently just for why a peer rejects TCP SYNs (ACL rejection, shields up, and in the future: nothing listening, something listening on that port but wrong interface, etc) Updates #1094 Updates tailscale/corp#1185 Signed-off-by: Brad Fitzpatrick <bradfitz@tailscale.com>	4 years ago

Brad Fitzpatrick	5611f290eb	ipn, ipnserver: only require sudo on Linux for mutable CLI actions This partially reverts `d6e9fb1df0`, which modified the permissions on the tailscaled Unix socket and thus required "sudo tailscale" even for "tailscale status". Instead, open the permissions back up (on Linux only) but have the server look at the peer creds and only permit read-only actions unless you're root. In the future we'll also have a group that can do mutable actions. On OpenBSD and FreeBSD, the permissions on the socket remain locked down to 0600 from `d6e9fb1df0`.

Smitty	2bf49ddf90	Provide example when format string is rate limited Here's an example log line in the new format: [RATE LIMITED] format string "open-conn-track: timeout opening %v; no associated peer node" (example: "open-conn-track: timeout opening ([ip] => [ip]); no associated peer node") This should make debugging logging issues a bit easier, and give more context as to why something was rate limited.

Smitty	b2a08ddacd	wgengine/tsdns: return NOERROR instead of NOTIMP for most records This is what every other DNS resolver I could find does, so tsdns should do it to.

Denton Gentry	b771a1363b	logtail: start a local server for TestFastShutdown Right now TestFastShutdown tries to upload logs to localhost:1234, which will most likely respond with an error. However if one has an actual service running on port 1234, it would receive a connection attempting to POST every time the unit test runs. Start a local server and direct the upload there instead.

Denton Gentry	2e9728023b	magicsock: test error case in sendDiscoMessage In sendDiscoMessage there is a check of whether the connection is closed, which is not being reliably exercised by other tests.

Denton Gentry	2c328da094	logtail: add a test to upload logs to local server Start an HTTP server to accept POST requests, and upload some logs to it. Check that uploaded logs were received.
