Brad Fitzpatrick	ed5d5f920f	net/interfaces: add interfaces.State.String method	4 years ago
Josh Bleecher Snyder	9784cae23b	util/uniq: add new package This makes it easy to compact slices that contain duplicate elements by sorting and then uniqing. This is an alternative to constructing an intermediate map and then extracting elements from it. It also provides more control over equality than using a map key does. Signed-off-by: Josh Bleecher Snyder <josh@tailscale.com>	4 years ago
Brad Fitzpatrick	12e28aa87d	ipn: on transition from no PAC to PAC, reset state So previous routes aren't shadowing resources that the operating system might need (Windows Domain Controller, DNS server, corp HTTP proxy, WinHTTP fetching the PAC file itself, etc). This effectively detects when we're transitioning from, say, public wifi to corp wifi and makes Tailscale remove all its routes and stops its TCP connections and tries connecting to everything anew. Updates tailscale/corp#653	4 years ago
Brad Fitzpatrick	cab3eb995f	net/interfaces: quiet PAC detection logging in no-PAC case, add benchmark	4 years ago
Josh Bleecher Snyder	38dda1ea9e	all: update depaware.txt Broken by `8051ecff55`. Signed-off-by: Josh Bleecher Snyder <josh@tailscale.com>	4 years ago
Brad Fitzpatrick	8051ecff55	net/interfaces: add State.PAC field, populate it on Windows Not used for anything yet (except logging), but populate the current proxy autoconfig PAC URL in Interfaces.State. A future change will do things based on it.	4 years ago
Brad Fitzpatrick	b5a3850d29	control/controlclient, ipn: store machine key separately from user prefs/persist Updates #610 (fixes after some win/xcode changes in a separate repo)	4 years ago

Brad Fitzpatrick	c8f257df00	Revert "all: keep UserProfiles a slice instead of a map for longer" This reverts commit `e5894aba42`. Breaks macOS/iOS build. Reverting per chat with Josh; he'll fix later today.	4 years ago
Brad Fitzpatrick	90b7293b3b	ipn: add/move some constants, update a comment And make the StateStore implementations be Stringers, for error messages.	4 years ago
Josh Bleecher Snyder	1fecf87363	control/controlclient: use wgcfg.PrivateKey.IsZero Generated by eg using template: --- package p import "github.com/tailscale/wireguard-go/wgcfg" func before(k wgcfg.PrivateKey) bool { return k == wgcfg.PrivateKey{} } func after(k wgcfg.PrivateKey) bool { return k.IsZero() } Signed-off-by: Josh Bleecher Snyder <josh@tailscale.com>	4 years ago
Josh Bleecher Snyder	2b8d2babfa	tailcfg: add IsZero methods to UserID and NodeID These will be helpful for doing some automated refactoring. Signed-off-by: Josh Bleecher Snyder <josh@tailscale.com>	4 years ago

David Anderson	c493e5804f	wgengine/router: make v6-ness configurable in test, for consistent results. Signed-off-by: David Anderson <danderson@tailscale.com>	4 years ago
Josh Bleecher Snyder	d3701417fc	tailcfg: fix typo in comment Signed-off-by: Josh Bleecher Snyder <josh@tailscale.com>	4 years ago
Brad Fitzpatrick	c86761cfd1	Remove tuntap references. We only use TUN.	4 years ago
Brad Fitzpatrick	8b94a769be	cmd/tailscaled: use the standard flag page instead of getopt Per discussion with @crawshaw. The CLI tool already used std flag anyway. If either of them, it would've made more sense for the CLI to use getopt.	4 years ago
Brad Fitzpatrick	94a68a113b	go.sum: tidy	4 years ago
Brad Fitzpatrick	01098f41d0	wgengine/tstun: fix typo in comment	4 years ago
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. Signed-off-by: Josh Bleecher Snyder <josh@tailscale.com>	4 years ago
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	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	64a24e796b	wgengine/tstun: fix 32-bit alignment again	4 years ago
Brad Fitzpatrick	afb2be71de	wgengine: add two missing TUN close calls	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
