David Anderson	33c541ae30	ipn/ipnlocal: populate self status from netmap in ipnlocal, not magicsock. Fixes #1933 Signed-off-by: David Anderson <danderson@tailscale.com>	3 years ago
Denton Gentry	e121c2f724	logpolicy: export NewLogtailTransport for Android Android doesn't use logpolicy and currently has enough unique stuff about its logging that makes it difficult to do so. For example, its logsDir comes from Gio. Export NewLogtailTransport to let Android use it.

Josh Bleecher Snyder	9f00510833	net/dns: handle comments in resolv.conf Currently, comments in resolv.conf cause our parser to fail, with error messages like: ParseIP("192.168.0.100 # comment"): unexpected character (at " # comment") Fix that. Noticed while looking through logs. Signed-off-by: Josh Bleecher Snyder <josh@tailscale.com>	3 years ago
Josh Bleecher Snyder	955aa188b3	ipn/ipnlocal: fix logging We were missing an argument here. Also, switch to %q, in case anything weird is happening with these strings. Updates tailscale/corp#461 Signed-off-by: Josh Bleecher Snyder <josh@tailscale.com>	3 years ago
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
Josh Bleecher Snyder	60510a6ae7	.github/workflows: check that repo is clean after build and test Linux-only for now, to avoid having to figure out why powershell doesn't like my shell scripting.

Josh Bleecher Snyder	ca1b3fe235	net/tshttpproxy: use correct size for Windows BOOL argument The Windows BOOL type is an int32. We were using a bool, which is a one byte wide. This could be responsible for the ERROR_INVALID_PARAMETER errors we were seeing for calls to WinHttpGetProxyForUrl. We manually checked all other existing Windows syscalls for similar mistakes and did not find any.

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.

Josh Bleecher Snyder	1a629a4715	net/portmapper: mark fewer PMP probe failures as unexpected There are lots of lines in the logs of the form: portmapper: unexpected PMP probe response: {OpCode:128 ResultCode:3 SecondsSinceEpoch:NNN MappingValidSeconds:0 InternalPort:0 ExternalPort:0 PublicAddr:0.0.0.0} ResultCode 3 here means a network failure, e.g. the NAT box itself has not obtained a DHCP lease. This is not an indication that something is wrong in the Tailscale client, so use different wording here to reflect that. Keep logging, so that we can analyze and debug the reasons that PMP probes fail. Signed-off-by: Josh Bleecher Snyder <josh@tailscale.com>	3 years ago

Brad Fitzpatrick	49a3fcae78	log/filelogger: make filelogger remove redundant date before adding a date At some point since filelogger was added on Windows, the log hierarchy above it changed such that a log.Printf writes to filelogger and includes the log package's own date. But then filelogger adds another. Rather than debug everything above and risk removing the prefix when run by tailscaled, instead just remove the log package's prefix very late right before we go to add the filelogger's own.

Brad Fitzpatrick	d24ed3f68e	wgengine/router: add debug knob to resort to Linux "ip" command usage Tailscale 1.18 uses netlink instead of the "ip" command to program the Linux kernel.

Josh Bleecher Snyder	b3d6704aa3	wgengine/magicsock: fix data race on endpoint.discoKey endpoint.discoKey is protected by endpoint.mu. endpoint.sendDiscoMessage was reading it without holding the lock. This showed up in a CI failure and is readily reproducible locally. The fix is in two parts. First, for Conn.enqueueCallMeMaybe, eliminate the one-line helper method endpoint.sendDiscoMessage; call Conn.sendDiscoMessage directly. This makes it more natural to read endpoint.discoKey in a context in which endpoint.mu is already held. Second, for endpoint.sendDiscoPing, explicitly pass the disco key as an argument. Again, this makes it easier to read endpoint.discoKey in a context in which endpoint.mu is already held. Signed-off-by: Josh Bleecher Snyder <josh@tailscale.com>	3 years ago
