Josh Bleecher Snyder	e16cb523aa	net/nettest: deflake TestPipeTimeout The block-write and block-read tests are both flaky, because each assumes it can get a normal read/write completed within 10ms. This isn’t always true. We can’t increase the timeouts, because that slows down the test. However, we don’t need to issue a regular read/write for this test. The immediately preceding tests already test this code, using a far more generous timeout. Remove the extraneous read/write. This drops the failure rate from 1 per 20,000 to undetectable on my machine. While we’re here, fix a typo in a debug print statement.

David Anderson	097602b3ca	ipn/ipnlocal: warn more precisely about IP forwarding issues on linux. If IP forwarding is disabled globally, but enabled per-interface on all interfaces, don't complain.

David Anderson	db800ddeac	cmd/derper: set Content-Security-Policy on DERPs. It's a basic "deny everything" policy, since DERP's HTTP server is very uninteresting from a browser POV.

Josh Bleecher Snyder	73beaaf360	net/tstun: rate limit "self disco out packet" logging When this happens, it is incredibly noisy in the logs. It accounts for about a third of all remaining "unexpected" log lines from a recent investigation. It's not clear that we know how to fix this, we have a functioning workaround, and we now have a (cheap and efficient) metric for this that we can use for measurements. So reduce the logging to approximately once per minute. Signed-off-by: Josh Bleecher Snyder <josh@tailscale.com>	3 years ago

Josh Bleecher Snyder	ad5e04249b	wgengine/monitor: ignore adding/removing uninteresting IPs One of the most common "unexpected" log lines is: "network state changed, but stringification didn't" One way that this can occur is if an interesting interface (non-Tailscale, has interesting IP address) gains or loses an uninteresting IP address (link local or loopback). The fact that the interface is interesting is enough for EqualFiltered to inspect it. The fact that an IP address changed is enough for EqualFiltered to declare that the interfaces are not equal. But the State.String method reasonably declines to print any uninteresting IP addresses. As a result, the network state appears to have changed, but the stringification did not. The String method is correct; nothing interesting happened. This change fixes this by adding an IP address filter to EqualFiltered in addition to the interface filter. This lets the network monitor ignore the addition/removal of uninteresting IP addresses. Signed-off-by: Josh Bleecher Snyder <josh@tailscale.com>	3 years ago

Aaron Klotz	7d8feb2784	hostinfo: change Windows implementation to directly query version information using API and registry We replace the cmd.exe invocation with RtlGetNtVersionNumbers for the first three fields. On Windows 10+, we query for the fourth field which is available via the registry. The fourth field is not really documented anywhere; Firefox has been querying it successfully since Windows 10 was released, so we can be pretty confident in its longevity at this point.
