David Anderson	8432999835	Move wgengine/tsdns to net/dns. Straight move+fixup, no other changes. In prep for merging with wgengine/router/dns. Signed-off-by: David Anderson <danderson@tailscale.com>	4 years ago
Brad Fitzpatrick	2384c112c9	net/packet, wgengine/{filter,tstun}: add TSMP ping Fixes #1467 Signed-off-by: Brad Fitzpatrick <bradfitz@tailscale.com>	4 years ago
Naman Sood	770aa71ffb	client, cmd/hello, ipn, wgengine: fix whois for netstack-forwarded connections Updates #504 Updates #707 Signed-off-by: Naman Sood <mail@nsood.in>	4 years ago
Brad Fitzpatrick	ffa70a617d	wgengine{,/monitor}: restore Engine.LinkChange, add Mon.InjectEvent The Engine.LinkChange method was recently removed in `e3df29d488` while misremembering how Android's link state mechanism worked. Rather than do some last minute rearchitecting of link state on Android before Tailscale 1.6, restore the old Engine.LinkChange hook for now so the Android client doesn't need any changes. But change how it's implemented to instead inject an event into the link monitor. Fixes #1427 Signed-off-by: Brad Fitzpatrick <bradfitz@tailscale.com>	4 years ago
Brad Fitzpatrick	e3df29d488	wgengine{,/monitor}: move interface state fetching/comparing to monitor Gets it out of wgengine so the Engine isn't responsible for being a callback registration hub for it. This also removes the Engine.LinkChange method, as it's no longer necessary. The monitor tells us about changes; it doesn't seem to need any help. (Currently it was only used by Swift, but as of `14dc790137` we just do the same from Go) Signed-off-by: Brad Fitzpatrick <bradfitz@tailscale.com>	4 years ago
Brad Fitzpatrick	1e7a35b225	types/netmap: split controlclient.NetworkMap off into its own leaf package Updates #1278 Signed-off-by: Brad Fitzpatrick <bradfitz@tailscale.com>	4 years ago
Brad Fitzpatrick	d76334d2f0	ipn: split LocalBackend off into new ipn/ipnlocal package And move a couple other types down into leafier packages. Now cmd/tailscale doesn't bring in netlink, magicsock, wgengine, etc. Fixes #1181 Signed-off-by: Brad Fitzpatrick <bradfitz@tailscale.com>	4 years ago
Josh Bleecher Snyder	fe7c3e9c17	all: move wgcfg from wireguard-go This is mostly code movement from the wireguard-go repo. Most of the new wgcfg package corresponds to the wireguard-go wgcfg package. wgengine/wgcfg/device{_test}.go was device/config{_test}.go. There were substantive but simple changes to device_test.go to remove internal package device references. The API of device.Config (now wgcfg.DeviceConfig) grew an error return; we previously logged the error and threw it away. Signed-off-by: Josh Bleecher Snyder <josh@tailscale.com>	4 years ago
Naman Sood	420c7a35e2	wgengine/netstack: use tailscale IPs instead of a hardcoded one (#1131 ) Signed-off-by: Naman Sood <mail@nsood.in>	4 years ago
Josh Bleecher Snyder	654b5f1570	all: convert from []wgcfg.Endpoint to string This eliminates a dependency on wgcfg.Endpoint, as part of the effort to eliminate our wireguard-go fork. Signed-off-by: Josh Bleecher Snyder <josh@tailscale.com>	4 years ago
Brad Fitzpatrick	587bdc4280	ipn, wgengine: disable subnet routes if network has PAC configuration Not configurable yet. Updates tailscale/corp#653 Signed-off-by: Brad Fitzpatrick <bradfitz@tailscale.com>	4 years ago
Brad Fitzpatrick	9b07517f18	wgengine: add Engine.SetLinkChangeCallback Start of making the IPN state machine react to link changes and down its DNS & routes if necessary to unblock proxy resolution (e.g. for transitioning from public to corp networks where the corp network has mandatory proxies and WPAD PAC files that can't be resolved while using the DNS/routes configured previously) This change should be a no-op. Just some callback plumbing.	4 years ago
Brad Fitzpatrick	84dc891843	cmd/tailscale/cli: add ping subcommand For example: $ tailscale ping -h USAGE ping <hostname-or-IP> FLAGS -c 10 max number of pings to send -stop-once-direct true stop once a direct path is established -verbose false verbose output $ tailscale ping mon.ts.tailscale.com pong from monitoring (100.88.178.64) via DERP(sfo) in 65ms pong from monitoring (100.88.178.64) via DERP(sfo) in 252ms pong from monitoring (100.88.178.64) via [2604:a880:2:d1::36:d001]:41641 in 33ms Fixes #661 Signed-off-by: Brad Fitzpatrick <bradfitz@tailscale.com>	4 years ago
Brad Fitzpatrick	6196b7e658	wgengine/magicsock: change API to not permit disco key changes Generate the disco key ourselves and give out the public half instead. Fixes #525	4 years ago
Brad Fitzpatrick	fe50cd0c48	ipn, wgengine: plumb NetworkMap down to magicsock Now we can have magicsock make decisions based on tailcfg.Debug settings sent by the server. Signed-off-by: Brad Fitzpatrick <bradfitz@tailscale.com>	4 years ago

Brad Fitzpatrick	e6b84f2159	all: make client use server-provided DERP map, add DERP region support Instead of hard-coding the DERP map (except for cmd/tailscale netcheck for now), get it from the control server at runtime. And make the DERP map support multiple nodes per region with clients picking the first one that's available. (The server will balance the order presented to clients for load balancing) This deletes the stunner package, merging it into the netcheck package instead, to minimize all the config hooks that would've been required. Also fix some test flakes & races. Fixes #387 (Don't hard-code the DERP map) Updates #388 (Add DERP region support) Fixes #399 (wgengine: flaky tests) Signed-off-by: Brad Fitzpatrick <bradfitz@tailscale.com>	5 years ago
David Anderson	9ccbcda612	wgengine/router: rename config.Settings to config.Config, make pointer. Signed-off-by: David Anderson <danderson@tailscale.com>	5 years ago
David Anderson	72cae5504c	wgengine: generate and plumb router.Settings in from ipn. This saves a layer of translation, and saves us having to pass in extra bits and pieces of the netmap and prefs to wgengine. Now it gets one Wireguard config, and one OS network stack config.

David Anderson	1ac570def7	wgengine/router: split out from wgengine. The router implementations are logically separate, with their own API. Signed-off-by: David Anderson <danderson@tailscale.com>	5 years ago

Avery Pennarun	f53e78e0d5	wgengine: don't lose filter state on filter reconfig. We were abandoning the UDP port LRU every time we got a new packet filter from tailcontrol, which caused return packets to suddenly stop arriving.	5 years ago
David Crawshaw	addbdce296	wgengine, ipn: include number of active DERPs in status Use this when making the ipn state transition from Starting to Running. This way a network of quiet nodes with no active handshaking will still transition to Active. Signed-off-by: David Crawshaw <crawshaw@tailscale.com>	5 years ago

Brad Fitzpatrick	79295b1138	wgengine: simplify, change some signatures * make RouterGen return an error, not take both tunname and tundev * also remove RouteGen taking a wireguard/device.Device; currently unused * remove derp parameter (it'll work differently) * unexport NewUserspaceRouter in per-OS impls, add documented wrapper Signed-off-by: Brad Fitzpatrick <bradfitz@tailscale.com>	5 years ago

David Anderson	a07906d1d8	wgengine: make SetRoutesFunc less appealing to use. It exists as a way to glue the mac-specific xcode logic with the OSS logic, and shouldn't be used by anything but the xcode glue.	5 years ago
