David Crawshaw	bdb91a20eb	ipnstate, ipnlocal: add AuthURL to status Signed-off-by: David Crawshaw <crawshaw@tailscale.com>	3 years ago
David Anderson	d79a2f3809	wgengine/filter: only log packets to/from non-default routes. Fixes tailscale/corp#1429. Signed-off-by: David Anderson <danderson@tailscale.com>	3 years ago
Brad Fitzpatrick	43b30e463c	ipn/ipnserver: refactor permissions checks a bit, document more, fix Windows Windows was only running the localapi on the debug port which was a stopgap at the time while doing peercreds work. Removed that, and wired it up correctly, with some more docs. More clean-up to do after 1.6, moving the localhost TCP auth code into the peercreds package. But that's too much for now, so the docs will have to suffice, even if it's at a bit of an awkward stage with the newly-renamed "NotWindows" field, which still isn't named well, but it's better than its old name of "Unknown" which hasn't been accurate since unix sock peercreds work anyway.

Brad Fitzpatrick	a4b585947d	ipn/localapi, client/tailscale: add a goroutine dump handler Signed-off-by: Brad Fitzpatrick <bradfitz@tailscale.com>	3 years ago
Brad Fitzpatrick	1ca3e739f7	ipn/ipnserver: set PermitWrite on localapi handler The TODO was easy now with peerCreds and the isReadonlyConn func. Signed-off-by: Brad Fitzpatrick <bradfitz@tailscale.com>	3 years ago
Brad Fitzpatrick	affd859121	ipn/ipnlocal, control/controlclient: propagate link monitor to controlclient Don't use it yet, but get it down there. Updates #1455 Signed-off-by: Brad Fitzpatrick <bradfitz@tailscale.com>	3 years ago
Brad Fitzpatrick	82edf94df7	ipn/ipnlocal: make IPv6 OS routes be a single /48 for our ULA space And if we have over 10,000 CGNAT routes, just route the entire CGNAT range. (for the hello test server) Fixes #1450 Signed-off-by: Brad Fitzpatrick <bradfitz@tailscale.com>	3 years ago
Brad Fitzpatrick	15b6969a95	ipn/ipnserver: grant client r/w access if peer uid matches tailscaled Signed-off-by: Brad Fitzpatrick <bradfitz@tailscale.com>	3 years ago
Brad Fitzpatrick	be779b3587	safesocket, ipn/ipnserver: unify peercred info, fix bug on FreeBSD etc FreeBSD wasn't able to run "tailscale up" since the recent peercred refactoring. Signed-off-by: Brad Fitzpatrick <bradfitz@tailscale.com>	3 years ago
Brad Fitzpatrick	625c413508	ipn/ipnlocal: fix another regression from link monitoring refactor Prior to `e3df29d488`, the Engine.SetLinkChangeCallback fired immediately, even if there was no change. The ipnlocal code apparently depended on that, and it broke integration tests (which live in another repo). So mimic the old behavior and call the ipnlocal callback immediately at init. Signed-off-by: Brad Fitzpatrick <bradfitz@tailscale.com>	3 years ago
David Anderson	f647e3daaf	ipn/ipnlocal: transform default routes into "all but LAN" routes. Fixes #1177. Signed-off-by: David Anderson <danderson@tailscale.com>	3 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>	3 years ago
Brad Fitzpatrick	38dc6fe758	cmd/tailscaled, wgengine: remove --fake, replace with netstack And add a --socks5-server flag.

David Anderson	2404c0ffad	ipn/ipnlocal: only filter out default routes when computing the local wg config. UIs need to see the full unedited netmap in order to know what exit nodes they can offer to the user. Signed-off-by: David Anderson <danderson@tailscale.com>	3 years ago

Brad Fitzpatrick	d3efe8caf6	safesocket, ipn/ipnserver: look up peer creds on Darwin And open up socket permissions like Linux, now that we know who connections are from.

David Anderson	e86b39b73f	ipn/ipnlocal: don't short-circuit default route filtering. If no exit node is specified, the filter must still run to remove offered default routes from all peers. Signed-off-by: David Anderson <danderson@tailscale.com>	3 years ago

Brad Fitzpatrick	ddfcc4326c	types/persist: split controlclient.Persist into a small leaf package This one alone doesn't modify the global dependency map much (depaware.txt if anything looks slightly worse), but it leave controlclient as only containing NetworkMap: bradfitz@tsdev:~/src/tailscale.com/ipn$ grep -F "controlclient." .go backend.go: NetMap controlclient.NetworkMap // new netmap received fake_test.go: b.notify(Notify{NetMap: &controlclient.NetworkMap{}}) fake_test.go: b.notify(Notify{NetMap: &controlclient.NetworkMap{}}) handle.go: netmapCache controlclient.NetworkMap handle.go:func (h Handle) NetMap() *controlclient.NetworkMap { Once that goes into a leaf package, then ipn doesn't depend on controlclient at all, and then the client gets smaller.

Josh Bleecher Snyder	e8cd7bb66f	tstest: simplify goroutine leak tests Use tb.Cleanup to simplify both the API and the implementation. One behavior change: When the number of goroutines shrinks, don't log. I've never found these logs to be useful, and they frequently add noise.

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>	3 years ago

Brad Fitzpatrick	b560386c1a	net/packet, wgengine, tstun: add inter-node TSMP protocol for connect errors This adds a new IP Protocol type, TSMP on protocol number 99 for sending inter-tailscale messages over WireGuard, currently just for why a peer rejects TCP SYNs (ACL rejection, shields up, and in the future: nothing listening, something listening on that port but wrong interface, etc) Updates #1094 Updates tailscale/corp#1185 Signed-off-by: Brad Fitzpatrick <bradfitz@tailscale.com>	3 years ago
Brad Fitzpatrick	5611f290eb	ipn, ipnserver: only require sudo on Linux for mutable CLI actions This partially reverts `d6e9fb1df0`, which modified the permissions on the tailscaled Unix socket and thus required "sudo tailscale" even for "tailscale status". Instead, open the permissions back up (on Linux only) but have the server look at the peer creds and only permit read-only actions unless you're root. In the future we'll also have a group that can do mutable actions. On OpenBSD and FreeBSD, the permissions on the socket remain locked down to 0600 from `d6e9fb1df0`.

Brad Fitzpatrick	5aa5db89d6	cmd/tailscaled, wgengine/netstack: add start of gvisor userspace netstack work Not usefully functional yet (mostly a proof of concept), but getting it submitted for some work @namansood is going to do atop this.

Brad Fitzpatrick	5efb0a8bca	cmd/tailscale: change formatting of "tailscale status" * show DNS name over hostname, removing domain's common MagicDNS suffix. only show hostname if there's no DNS name. but still show shared devices' MagicDNS FQDN. * remove nerdy low-level details by default: endpoints, DERP relay, public key. They're available in JSON mode still for those who need them. * only show endpoint or DERP relay when it's active with the goal of making debugging easier. (so it's easier for users to understand what's happening) The asterisks are gone. * remove Tx/Rx numbers by default for idle peers; only show them when there's traffic. * include peers' owner login names * add CLI option to not show peers (matching --self=true, --peers= also defaults to true) * sort by DNS/host name, not public key * reorder columns	4 years ago
Josh Bleecher Snyder	18471a8792	ipn: close logger at the end of TestLocalLogLines If any goroutine continues to use the logger in TestLocalLogLines after the test finishes, the test panics. The culprit for this was wireguard-go; the previous commit fixed that. This commit adds suspenders: When the test is done, make logging calls into no-ops.
