Brad Fitzpatrick	73cc2d8f89	wgengine/filter: also silently drop link-local unicast traffic Updates #629	4 years ago
Brad Fitzpatrick	5f807c389e	wgengine/filter: drop multicast packets out, don't log about them Eventually we'll probably support multicast. For now it's just log spam. Fixes #629	4 years ago
Brad Fitzpatrick	bbb56f2303	wgengine/router: fix tests on Debian Buster as regular user on machine with IPv6	4 years ago
David Anderson	fddbcb0c7b	wgengine/router: support various degrees of broken IPv6. Gracefully skips touching the v6 NAT table on systems that don't have it, and doesn't configure IPv6 at all if IPv6 is globally disabled. Signed-off-by: David Anderson <danderson@tailscale.com>	4 years ago
David Anderson	0d80904fc2	wgengine/router: set up basic IPv6 routing/firewalling. Part of #19. Signed-off-by: David Anderson <danderson@tailscale.com>	4 years ago
Josh Bleecher Snyder	f0ef561049	wgengine/tsdns: use netns to obtain a socket Fixes #789 Signed-off-by: Josh Bleecher Snyder <josh@tailscale.com>	4 years ago
Josh Bleecher Snyder	6e8328cba5	wgengine/tsdns: replace connections when net link changes (macOS) When the network link changes, existing UDP sockets fail immediately and permanently on macOS. The forwarder set up a single UDP conn and never changed it. As a result, any time there was a network link change, all forwarded DNS queries failed. To fix this, create a new connection when send requests fail because of network unreachability. This change is darwin-only, although extended it to other platforms should be straightforward.

Josh Bleecher Snyder	1fd10061fd	wgengine/tsdns: delegate bonjour service rdns requests While we're here, parseQuery into a plain function. This is helpful for fuzzing. (Which I did a bit of. Didn't find anything.) And clean up a few minor things. Signed-off-by: Josh Bleecher Snyder <josh@tailscale.com>	4 years ago
Brad Fitzpatrick	2d0ed99672	wgengine, wgengine/router: add a bunch of (temporary?) engine creation logging Trying to debug what's slow on a user's machine. Updates #785	4 years ago
Brad Fitzpatrick	7c11f71ac5	wgengine/router: ignore errors deleting 169.254.255.255/32 route on Windows Updates #785	4 years ago
David Anderson	b7e0ff598a	wgengine: don't close tundev in NewUserspaceEngine. newUserspaceEngineAdvanced closes the tun device on error already. Fixes #783. Signed-off-by: David Anderson <danderson@tailscale.com>	4 years ago
Brad Fitzpatrick	a601a760ba	version: add Windows MAJOR,MINOR,BUILD,REVISON value Updates #778 Signed-off-by: Brad Fitzpatrick <bradfitz@tailscale.com>	4 years ago
Brad Fitzpatrick	8893c2ee78	net/interfaces, net/netns: move default route interface code to interfaces To populate interfaces.State.DefaultRouteInterface. Signed-off-by: Brad Fitzpatrick <bradfitz@tailscale.com>	4 years ago
Brad Fitzpatrick	fda9dc8815	net/netns: document Windows socket binding a bit more Signed-off-by: Brad Fitzpatrick <bradfitz@tailscale.com>	4 years ago
Brad Fitzpatrick	5d8b88be88	control/controlclient, version/distro, wgengine: recognize OpenWrt And help out with missing packages. Thanks to @willangley for tips. Updates #724	4 years ago
Brad Fitzpatrick	ec95e901e6	go.sum: update	4 years ago
Brad Fitzpatrick	3528d28ed1	wgengine/router: move Tailscale's winipcfg additions into wgengine/router Part of unforking our winipcfg-go and using upstream (#760), move our additions into our repo. (We might upstream them later if upstream has interest) Originally these were: @apenwarr: "Add ifc.SyncAddresses() and SyncRoutes()." `609dcf2df5` @bradfitz: "winipcfg: make Interface.AddRoutes do as much as possible, return combined error" `e9f93d53f3` @bradfitz: "prevent unnecessary Interface.SyncAddresses work; normalize IPNets in deltaNets" `decb9ee8e1`	4 years ago
Brad Fitzpatrick	56a787fff8	go.mod, go.sum: bump wireguard-go	4 years ago
Brad Fitzpatrick	fb03c60c9e	version: bump date	4 years ago
Brad Fitzpatrick	963b927d5b	net/tshttpproxy: appease staticcheck	4 years ago
Brad Fitzpatrick	fd77268770	wgengine/router: enumerate all interfaces when finding Tailscale adapter by GUID Might fix it. I've spent too much time failing to reproduce the issue. This doesn't seem to make it worse, though (it still runs for me), so I'll include this and see if it helps others while I still work on a reliable way to reproduce it. Updates tailscale/corp#474	4 years ago
Brad Fitzpatrick	5bcac4eaac	net/tshttpproxy: add GetProxyForURL negative cache Otherwise when PAC server is down, we log, and each log entry is a new HTTP request (from logtail) and a new GetProxyForURL call, which again logs, non-stop. This is also nicer to the WinHTTP service. Then also hook up link change notifications to the cache to reset it if there's a chance the network might work sooner.	4 years ago
Josh Bleecher Snyder	4cc0ed67f9	tailcfg: add MachineKey.IsZero Signed-off-by: Josh Bleecher Snyder <josh@tailscale.com>	4 years ago

Brad Fitzpatrick	abe095f036	wgengine/tstun: make Close safe for concurrent use	4 years ago
Brad Fitzpatrick	3bdcfa7193	ipn: remove DisableDERP pref We depend on DERP for NAT traversal now[0] so disabling it entirely can't work. What we'll do instead in the future is let people specify alternate/additional DERP servers. And perhaps in the future we could also add a pref for nodes to say when they expect to never need/want to use DERP for data (but allow it for NAT traversal communication). But this isn't the right pref and it doesn't work, so delete it. Fixes #318 [0] https://tailscale.com/blog/how-nat-traversal-works/	4 years ago
Christina Wen	f0e9dcdc0a	wgengine/router: restore /etc/resolv.conf after tailscale down is called This change is to restore /etc/resolv.conf after tailscale down is called. This is done by setting the dns.Manager before errors occur. Error collection is also added. Fixes #723	4 years ago
Brad Fitzpatrick	904a91038a	tailcfg: add MapRequest.ReadOnly and OmitPeers; remove DebugForceDisco DebugForceDisco was a development & safety knob during the the transition to discovery. It's no longer needed. Add MapRequest.ReadOnly to prevent clients needing to do two peer-spamming MapRequest at start-up. This only adds the field, not the use of the field. (The control server needs to support it first.) Updates tailscale/corp#557 Signed-off-by: Brad Fitzpatrick <bradfitz@tailscale.com>	4 years ago
Brad Fitzpatrick	c41947903a	ipn: don't log if legacy prefs don't exist (the normal case these days)	4 years ago
David Crawshaw	815bf017fc	tsweb: when unwrapping HTTPError, record the user-facing message also in the log There's often some useful piece of information in there not already repeated in the internal error. Signed-off-by: David Crawshaw <crawshaw@tailscale.com>	4 years ago
David Crawshaw	dea3ef0597	tsweb: make JSONHandlerFunc implement ReturnHandler, not http.Handler This way something is capable of logging errors on the server. Fixes #766 Signed-off-by: David Crawshaw <crawshaw@tailscale.com>	4 years ago
Brad Fitzpatrick	3aeb2e204c	go.mod: bump github.com/tailscale/winipcfg-go for some Windows fixes	4 years ago

Christina Wen	48fbe93e72	wgengine/magicsock: clarify pre-disco 'tailscale ping' error message This change clarifies the error message when a user pings a peer that is using an outdated version of Tailscale.	4 years ago
Brad Fitzpatrick	96fd20e3c0	ipn: bail out a bit earlier when a peer doesn't have a DNS name It's properly handled later in tsdns.NewMap anyway, but there's work done in the meantime that can be skipped when a peer lacks a DNS name. It's also more clear that it's okay for it to be blank.	4 years ago
Josh Bleecher Snyder	7f97cf654d	cmd/microproxy: add -insecure flag This makes it easier to run microproxy locally during development. Signed-off-by: Josh Bleecher Snyder <josh@tailscale.com>	4 years ago

Christina Wen	e862f90e34	wgengine/router/router_linux.go: fixed " route del failed" error (#756 ) * wgengine/router/router_linux.go: Switched `cidrDiff("addr")` and `cidrDiff("route")` order Signed-off-by: Christina Wen <christina@tailscale.com> Co-authored-by: Christina Wen <christina@tailscale.com>	4 years ago

Brad Fitzpatrick	88107b1287	control/controlclient: add TS_DEBUG_MAPRESPONSE to dump all MapResponses I'm always adding this by hand during development. Time to check it in.	4 years ago

Brad Fitzpatrick	7e9d1f7808	wgengine/router: tighten isMissingIPv6Err So it doesn't false positive if misused. Signed-off-by: Brad Fitzpatrick <bradfitz@tailscale.com>	4 years ago
David Anderson	8f5b52e571	net/netns: add windows support. Also remove rebinding logic from the windows router. Magicsock will instead rebind based on link change signals. Signed-off-by: David Anderson <danderson@tailscale.com>	4 years ago
Josh Bleecher Snyder	3f4d93feb2	go.mod: bump depaware to get diffs out of -check, again I had to use go get -u github.com/tailscale/depaware@e09ee10c18249e4bf198e66bbd47babcd502637a to force it to the correct version; it kept selecting head~1. Maybe because the branch is called main instead of master? Maybe because of some delay?	4 years ago
Josh Bleecher Snyder	a5d701095b	wgengine/magicsock: increase test timeout to reduce flakiness Updates #654. See that issue for a discussion of why this timeout reduces flakiness, and what next steps are. Signed-off-by: Josh Bleecher Snyder <josh@tailscale.com>	4 years ago
Josh Bleecher Snyder	0c0239242c	wgengine/magicsock: make discoPingPurpose a stringer It was useful for debugging once, it'll probably be useful again. Signed-off-by: Josh Bleecher Snyder <josh@tailscale.com>	4 years ago
Josh Bleecher Snyder	6e38d29485	wgengine/magicsock: improve test logging output This fixes line numbers and reduces timestamp precision to overwhelming the output. Signed-off-by: Josh Bleecher Snyder <josh@tailscale.com>	4 years ago
