Tom Proctor	5f22f72636	hostinfo,build_docker.sh,tailcfg: more reliably detect being in a container (#13826) ... Our existing container-detection tricks did not work on Kubernetes, where Docker is no longer used as a container runtime. Extends the existing go build tags for containers to the other container packages and uses that to reliably detect builds that were created by Tailscale for use in a container. Unfortunately this doesn't necessarily improve detection for users' custom builds, but that's a separate issue. Updates #13825 Signed-off-by: Tom Proctor <tomhjp@users.noreply.github.com>	2 weeks ago

Kristoffer Dalby	e0d711c478	{net/connstats,wgengine/magicsock}: fix packet counting in connstats ... connstats currently increments the packet counter whenever it is called to store a length of data, however when udp batch sending was introduced we pass the length for a series of packages, and it is only incremented ones, making it count wrongly if we are on a platform supporting udp batches.

Nick Khyl	f07ff47922	net/dns/resolver: add tests for using a forwarder with multiple upstream resolvers ... If multiple upstream DNS servers are available, quad-100 sends requests to all of them and forwards the first successful response, if any. If no successful responses are received, it propagates the first failure from any of them. This PR adds some test coverage for these scenarios.

Nick Hill	c2144c44a3	net/dns/resolver: update (*forwarder).forwardWithDestChan to always return an error unless it sends a response to responseChan ... We currently have two executions paths where (*forwarder).forwardWithDestChan returns nil, rather than an error, without sending a DNS response to responseChan. These paths are accompanied by a comment that reads: // Returning an error will cause an internal retry, there is // nothing we can do if parsing failed. Just drop the packet. But it is not (or no longer longer) accurate: returning an error from forwardWithDestChan does not currently cause a retry. Moreover, although these paths are currently unreachable due to implementation details, if (*forwarder).forwardWithDestChan were to return nil without sending a response to responseChan, it would cause a deadlock at one call site and a panic at another. Therefore, we update (*forwarder).forwardWithDestChan to return errors in those two paths and remove comments that were no longer accurate and misleading.

Nick Hill	e7545f2eac	net/dns/resolver: translate 5xx DoH server errors into SERVFAIL DNS responses ... If a DoH server returns an HTTP server error, rather than a SERVFAIL within a successful HTTP response, we should handle it in the same way as SERVFAIL. Updates #13571 Signed-off-by: Nick Hill <mykola.khyl@gmail.com>	3 weeks ago
Nick Hill	17335d2104	net/dns/resolver: forward SERVFAIL responses over PeerDNS ... As per the docstring, (*forwarder).forwardWithDestChan should either send to responseChan and returns nil, or returns a non-nil error (without sending to the channel). However, this does not hold when all upstream DNS servers replied with an error. We've been handling this special error path in (*Resolver).Query but not in (*Resolver).HandlePeerDNSQuery. As a result, SERVFAIL responses from upstream servers were being converted into HTTP 503 responses, instead of being properly forwarded as SERVFAIL within a successful HTTP response, as per RFC 8484, section 4.2.1: A successful HTTP response with a 2xx status code (see Section 6.3 of [RFC7231]) is used for any valid DNS response, regardless of the DNS response code. For example, a successful 2xx HTTP status code is used even with a DNS message whose DNS response code indicates failure, such as SERVFAIL or NXDOMAIN. In this PR we fix (*forwarder).forwardWithDestChan to no longer return an error when it sends a response to responseChan, and remove the special handling in (*Resolver).Query, as it is no longer necessary.

Nick Hill	9a73462ea4	types/lazy: add DeferredInit type ... It is sometimes necessary to defer initialization steps until the first actual usage or until certain prerequisites have been met. For example, policy setting and policy source registration should not occur during package initialization. Instead, they should be deferred until the syspolicy package is actually used. Additionally, any errors should be properly handled and reported, rather than causing a panic within the package's init function. In this PR, we add DeferredInit, to facilitate the registration and invocation of deferred initialization functions. Updates #12687 Signed-off-by: Nick Hill <mykola.khyl@gmail.com>	4 weeks ago
