Josh Bleecher Snyder	020084e84d	wgengine: adapt to removal of wgcfg.Key in wireguard-go	4 years ago
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. This change was proposed in a comment on #1110. Signed-off-by: Smitty <me@smitop.com>	4 years ago
Denton Gentry	ce058c8280	Revert "Add logtail tests (#1114 )" (#1116 ) This reverts commit `e4f53e9b6f`. At least two of these tests are flakey, reverting until they can be made more robust. Signed-off-by: Denton Gentry <dgentry@tailscale.com>	4 years ago
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. This also helps avoid weird error messages about non-existent records being unimplemented, and thus fixes #848. Signed-off-by: Smitty <me@smitop.com>	4 years ago
Denton Gentry	e4f53e9b6f	Add logtail tests (#1114 ) * logtail: test parseAndRemoveLogLevel() Signed-off-by: Denton Gentry <dgentry@tailscale.com> * logtail: test JSON log encoding. Expand TestUploadMessages to also exercise the encoding functions in logtail, like JSON logging and timestamps. Other tests frequently send logs but a) don't check the result and b) do so by happenstance, such that the lines in encode() were not consistently being exercised and leading to spurious changes in code coverage. Signed-off-by: Denton Gentry <dgentry@tailscale.com> * logtail: add a test for drainPendingMessages Make the client buffer some messages before the upload server becomes available. Signed-off-by: Denton Gentry <dgentry@tailscale.com> * logtail: use %q, raw strings, and io.WriteString %q escapes binary characters for us. raw strings avoid so much backslash escaping Signed-off-by: Denton Gentry <dgentry@tailscale.com>	4 years ago
Brad Fitzpatrick	b987b2ab18	control/controlclient: treat node sharer as owner for display purposes This make clients (macOS, Windows, tailscale status) show the node sharer's profile rather than the node owner (which may be anonymized). Updates #992	4 years ago
Brad Fitzpatrick	7acd3397d5	README: names of contributors, link to them instead	4 years ago

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. Signed-off-by: Denton Gentry <dgentry@tailscale.com>	4 years ago
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. This shows up in code coverage reports, the lines of code in sendDiscoMessage are alternately added and subtracted from code coverage. Add a test to specifically exercise and verify this code path.

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. Code in logtail:drainPending was not being reliably exercised by other tests. This shows up in code coverage reports, as lines of code in drainPending are alternately added and subtracted from code coverage. This test will reliably exercise and verify this code. Signed-off-by: Denton Gentry <dgentry@tailscale.com>	4 years ago
Denton Gentry	0aed59b691	portlist: add a test for SameInodes Exercise all cases. Signed-off-by: Denton Gentry <dgentry@tailscale.com>	4 years ago
Denton Gentry	07e4009e15	portlist: fully exercise lessThan in tests All cases in lessThan are not reliably exercised by other tests. This shows up in code coverage metrics as lines in lessThan are alternately added and removed from coverage. Add a test case to systematically test all conditions. Signed-off-by: Denton Gentry <dgentry@tailscale.com>	4 years ago
Denton Gentry	0aa55bffce	magicsock: test error case in derpWriteChanOfAddr In derpWriteChanOfAddr when we call derphttp.NewRegionClient(), there is a check of whether the connection is already errored and if so it returns before grabbing the lock. The lock might already be held and would be a deadlock. This corner case is not being reliably exercised by other tests. This shows up in code coverage reports, the lines of code in derpWriteChanOfAddr are alternately added and subtracted from code coverage. Add a test to specifically exercise this code path, and verify that it doesn't deadlock. This is the best tradeoff I could come up with: + the moment code calls Err() to check if there is an error, we grab the lock to make sure it would deadlock if it tries to grab the lock itself. + if a new call to Err() is added in this code path, only the first one will be covered and the rest will not be tested. + this test doesn't verify whether code is checking for Err() in the right place, which ideally I guess it would.

Brad Fitzpatrick	f85769b1ed	wgengine/magicsock: drop netaddr.IPPort cache netaddr.IP no longer allocates, so don't need a cache or all its associated code/complexity. This totally removes groupcache/lru from the deps. Also go mod tidy.	4 years ago

Brad Fitzpatrick	5aa5db89d6	cmd/tailscaled, wgengine/netstack: add start of gvisor userspace netstack work Not usefully functional yet (mostly a proof of concept), but getting it submitted for some work @namansood is going to do atop this.

Brad Fitzpatrick	5efb0a8bca	cmd/tailscale: change formatting of "tailscale status" * show DNS name over hostname, removing domain's common MagicDNS suffix. only show hostname if there's no DNS name. but still show shared devices' MagicDNS FQDN. * remove nerdy low-level details by default: endpoints, DERP relay, public key. They're available in JSON mode still for those who need them. * only show endpoint or DERP relay when it's active with the goal of making debugging easier. (so it's easier for users to understand what's happening) The asterisks are gone. * remove Tx/Rx numbers by default for idle peers; only show them when there's traffic. * include peers' owner login names * add CLI option to not show peers (matching --self=true, --peers= also defaults to true) * sort by DNS/host name, not public key * reorder columns	4 years ago

Josh Bleecher Snyder	1271e135cd	wgengine/tstun: initialize wireguard-go TUN parameters This will enable us to remove the corresponding code from our fork of wireguard-go. Signed-off-by: Josh Bleecher Snyder <josh@tailscale.com>	4 years ago
Josh Bleecher Snyder	18471a8792	ipn: close logger at the end of TestLocalLogLines If any goroutine continues to use the logger in TestLocalLogLines after the test finishes, the test panics. The culprit for this was wireguard-go; the previous commit fixed that. This commit adds suspenders: When the test is done, make logging calls into no-ops.

Josh Bleecher Snyder	1e4604f60e	wgengine: quiet some wireguard-go logging The log lines that wireguard-go prints as it starts and stops its worker routines are mostly noise. They also happen after other work is completed, which causes failures in some of the log testing packages. Signed-off-by: Josh Bleecher Snyder <josh@tailscale.com>	4 years ago

Denton Gentry	df64b7abf8	Add IPv6 Reverse DNS Lookup test. To be honest I'm not fond of Golden Bytes tests like this, but not so much as to want to rewrite the whole test. The DNS byte format is essentially immutable at this point, the encoded bytes aren't going to change. The rest of the test assumptions about hostnames might, but we can fix that when it comes.

Brad Fitzpatrick	2f04f49376	control/controlclient: use lite map request handler to avoid aborting streams Previously, any change to endpoints or hostinfo (or hostinfo's netinfo) would result in the long-running map request HTTP stream being torn down and restarted, losing all compression context along with it. This change makes us instead send a lite map request (OmitPeers: true, Stream: false) that doesn't subscribe to anything, and then the coordination server knows to not close other streams for that node when it recives a lite request.
