David Anderson	c0fcab01ac	client/tailscale: fix request object for key creation. The request takes key capabilities as an argument, but wrapped in a parent object. Signed-off-by: David Anderson <danderson@tailscale.com>	2 years ago
Andrew Dunham	3f4d51c588	net/dns: don't send on closed channel when message too large Previously, if a DNS-over-TCP message was received while there were existing queries in-flight, and it was over the size limit, we'd close the 'responses' channel. This would cause those in-flight queries to send on the closed channel and panic. Instead, don't close the channel at all and rely on s.ctx being canceled, which will ensure that in-flight queries don't hang. Fixes #6725 Signed-off-by: Andrew Dunham <andrew@du.nham.ca> Change-Id: I8267728ac37ed7ae38ddd09ce2633a5824320097	2 years ago

Andrew Dunham	0d47cd2284	wgengine/monitor: fix panic due to race on Windows It's possible for the 'somethingChanged' callback to be registered and then trigger before the ctx field is assigned; move the assignment earlier so this can't happen.

David Anderson	d81a2b2ce2	Makefile: add a target for doing dev builds of the k8s operator. Updates #502. Signed-off-by: David Anderson <danderson@tailscale.com>	2 years ago
David Anderson	9c77205ba1	cmd/k8s-operator: add more tests for "normal" paths. Tests cover configuring a proxy through an annotation rather than a LoadBalancerClass, and converting between those two modes at runtime. Updates #502. Signed-off-by: David Anderson <danderson@tailscale.com>	2 years ago
David Anderson	c902190e67	cmd/k8s-operator: factor out some of the larger expected test outputs. For other test cases, the operator is going to produce similar generated objects in several codepaths, and those objects are large. Move them out to helpers so that the main test code stays a bit more intelligible. The top-level Service that we start and end with remains in the main test body, because its shape at the start and end is one of the main things that varies a lot between test cases. Updates #502.

David Anderson	bc8f5a7734	cmd/k8s-operator: add a basic unit test. The test verifies one of the successful reconcile paths, where a client requests an exposed service via a LoadBalancer class. Updates #502. Signed-off-by: David Anderson <danderson@tailscale.com>	2 years ago
David Anderson	3b7ae39a06	cmd/k8s-operator: use the client's authkey method to create auth keys. Also introduces an intermediary interface for the tailscale client, in preparation for operator tests that fake out the Tailscale API interaction. Updates #502.

Joe Tsai	bd2995c14b	ipn/ipnlocal: simplify redactErr (#6716 ) Use multierr.Range to iterate through an error tree instead of multiple invocations of errors.As. This scales better as we add more Go error types to the switch. Signed-off-by: Joe Tsai <joetsai@digital-static.net>	2 years ago
Joe Tsai	c47578b528	util/multierr: add Range (#6643 ) Errors in Go are no longer viewed as a linear chain, but a tree. See golang/go#53435. Add a Range function that iterates through an error in a pre-order, depth-first order. This matches the iteration order of errors.As in Go 1.20. This adds the logic (but currently commented out) for having Error implement the multi-error version of Unwrap in Go 1.20. It is commented out currently since it causes "go vet" to complain about having the "wrong" signature. Signed-off-by: Joe Tsai <joetsai@digital-static.net>	2 years ago
Dave Anderson	041a0e3c27	client/tailscale: add APIs for auth key management. (#6715 ) client/tailscale: add APIs for key management. Updates #502. Signed-off-by: David Anderson <danderson@tailscale.com>	2 years ago
David Anderson	b2d4abf25a	cmd/k8s-operator: add a kubernetes operator. This was initially developed in a separate repo, but for build/release reasons and because go module management limits the damage of importing k8s things now, moving it into this repo. At time of commit, the operator enables exposing services over tailscale, with the 'tailscale' loadBalancerClass. It also currently requires an unreleased feature to access the Tailscale API, so is not usable yet. Updates #502. Signed-off-by: David Anderson <danderson@tailscale.com>	2 years ago
Mihai Parparita	47002d93a3	ipn/ipnlocal: add a few metrics for PeerAPI and LocalAPI Mainly motivated by wanting to know how much Taildrop is used, but also useful when tracking down how many invalid requests are generated. Signed-off-by: Mihai Parparita <mihai@tailscale.com>	2 years ago
Aaron Klotz	53e2010b8a	cmd/tailscaled: change Windows implementation to shut down subprocess via closing its stdin We've been doing a hard kill of the subprocess, which is only safe as long as both the cli and gui are not running and the subprocess has had the opportunity to clean up DNS settings etc. If unattended mode is turned on, this is definitely unsafe. I changed babysitProc to close the subprocess's stdin to make it shut down, and then I plumbed a cancel function into the stdin reader on the subprocess side.

Jordan Whited	ea5ee6f87c	all: update golang.zx2c4.com/wireguard to github.com/tailscale/wireguard-go (#6692 ) This is temporary while we work to upstream performance work in https://github.com/WireGuard/wireguard-go/pull/64.

Mihai Parparita	bdc45b9066	wgengine/magicsock: fix panic when rebinding fails We would replace the existing real implementation of nettype.PacketConn with a blockForeverConn, but that violates the contract of atomic.Value (where the type cannot change). Fix by switching to a pointer value (atomic.Pointer[nettype.PacketConn]). A longstanding issue, but became more prevalent when we started binding connections to interfaces on macOS and iOS (#6566), which could lead to the bind call failing if the interface was no longer available.

David Anderson	1b65630e83	cmd/containerboot: switch to IPN bus monitoring instead of polling. We still have to shell out to `tailscale up` because the container image's API includes "arbitrary flags to tailscale up", unfortunately. But this should still speed up startup a little, and also enables k8s-bound containers to update their device information as new netmap updates come in.

Aaron Klotz	98f21354c6	cmd/tailscaled: add a special command to tailscaled's Windows service for removing WinTun WinTun is installed lazily by tailscaled while it is running as LocalSystem. Based upon what we're seeing in bug reports and support requests, removing WinTun as a lesser user may fail under certain Windows versions, even when that user is an Administrator. By adding a user-defined command code to tailscaled, we can ask the service to do the removal on our behalf while it is still running as LocalSystem. * The uninstall code is basically the same as it is in corp; * The command code will be sent as a service control request and is protected by the SERVICE_USER_DEFINED_CONTROL access right, which requires Administrator. I'll be adding follow-up patches in corp to engage this functionality. Updates https://github.com/tailscale/tailscale/issues/6433 Signed-off-by: Aaron Klotz <aaron@tailscale.com>	2 years ago

Mihai Parparita	79f3a5d753	net/netns, net/interfaces: explicitly bind sockets to the default interface on all Darwin variants We were previously only doing this for tailscaled-on-Darwin, but it also appears to help on iOS. Otherwise, when we rebind magicsock UDP connections after a cellular -> WiFi interface change they still keep using cellular one. To do this correctly when using exit nodes, we need to exclude the Tailscale interface when getting the default route, otherwise packets cannot leave the tunnel. There are native macOS/iOS APIs that we can use to do this, so we allow those clients to override the implementation of DefaultRouteInterfaceIndex. Updates #6565, may also help with #5156 Signed-off-by: Mihai Parparita <mihai@tailscale.com>	2 years ago
