Naman Sood	07c3df13c6	wgengine/tstun: inform userspaceEngine about injected outbound packets in tundev Signed-off-by: Naman Sood <mail@nsood.in>	4 years ago
Josh Bleecher Snyder	e7caad61fb	wgengine: remove IpcGetOperation filter This was in place because retrieved allowed_ips was very expensive. Upstream changed the data structure to make them cheaper to compute. This commit is an experiment to find out whether they're now cheap enough.

Brad Fitzpatrick	6b365b0239	wgengine/magicsock: fix DERP reader hang regression during concurrent reads Fixes #1282 Signed-off-by: Brad Fitzpatrick <bradfitz@tailscale.com>	4 years ago
Josh Bleecher Snyder	e1f773ebba	wgengine/magicsock: allow more time for pings to transit We removed the "fast retry" code from our wireguard-go fork. As a result, pings can take longer to transit when retries are required. Allow that. Fixes #1277 Signed-off-by: Josh Bleecher Snyder <josh@tailscale.com>	4 years ago
Brad Fitzpatrick	6d2b8df06d	wgengine/magicsock: add disabled failing (deadlocking) test for #1282 The fix can make this test run unconditionally. This moves code from `5c619882bc` for testability but doesn't fix it yet. The #1282 problem remains (when I wrote its wake-up mechanism, I forgot there were N DERP readers funneling into 1 UDP reader, and the code just isn't correct at all for that case). Also factor out some test helper code from BenchmarkReceiveFrom. The refactoring in magicsock.go for testability should have no behavior change.	4 years ago
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>	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	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.

David Anderson	a046b48593	cmd/tailscale/cli: display currently active exit node in `tailscale status`. Signed-off-by: David Anderson <danderson@tailscale.com>	4 years ago
Brad Fitzpatrick	6064b6ff47	wgengine/wgcfg/nmcfg: split control/controlclient/netmap.go into own package It couldn't move to ipnlocal due to test dependency cycles. Updates #1278 Signed-off-by: Brad Fitzpatrick <bradfitz@tailscale.com>	4 years ago
Josh Bleecher Snyder	138055dd70	tstest/natlab: use net.ErrClosed instead of a new error Upstream wireguard-go decided to use errors.Is(err, net.ErrClosed) instead of checking the error string. It also provided an unsafe linknamed version of net.ErrClosed for clients running Go 1.15. Switch to that. This reduces the time required for the wgengine/magicsock tests on my machine from ~35s back to the ~13s it was before `456cf8a376`.

David Anderson	ace57d7627	wgengine/magicsock: set a dummy private key in benchmark. Magicsock started dropping all traffic internally when Tailscale is shut down, to avoid spurious wireguard logspam. This made the benchmark not receive anything. Setting a dummy private key is sufficient to get magicsock to pass traffic for benchmarking purposes. Fixes #1270.

David Anderson	b9c2231fdf	ipn: program exit node into the data plane according to user pref. Part of #1153, #1154. Fixes #1224. Signed-off-by: David Anderson <danderson@tailscale.com>	4 years ago

Brad Fitzpatrick	98f9e82c62	logpolicy: on Windows, use tailscale-ipn log name if it already existed For the migration to tailscaled.exe on Windows, don't create a new logid if one existed under the old filename. Updates #1232	4 years ago

Brad Fitzpatrick	d37058af72	net/packet: add some more TSMP packet reject reasons and MaybeBroken bit Unused for now, but I want to backport this commit to 1.4 so 1.6 can start sending these and then at least 1.4 logs will stringify nicely.

David Anderson	45fe06a89f	Revert "tailcfg: remove v6-overlay debug option." This reverts commit `da4ec54756`. Since v6 got disabled for Windows nodes, I need the debug flag back to figure out why it was broken. Signed-off-by: David Anderson <danderson@tailscale.com>	4 years ago
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.

Brad Fitzpatrick	a2aa6cd2ed	wgengine/router: clarify disabled IPv6 message on Linux	4 years ago
David Crawshaw	d139fa9c92	net/interfaces: use a uint32_t for ipv4 address The code was using a C "int", which is a signed 32-bit integer. That means some valid IP addresses were negative numbers. (In particular, the default router address handed out by AT&T fiber: 192.168.1.254. No I don't know why they do that.) A negative number is < 255, and so was treated by the Go code as an error. This fixes the unit test failure: $ go test -v -run=TestLikelyHomeRouterIPSyscallExec ./net/interfaces === RUN TestLikelyHomeRouterIPSyscallExec interfaces_darwin_cgo_test.go:15: syscall() = invalid IP, false, netstat = 192.168.1.254, true --- FAIL: TestLikelyHomeRouterIPSyscallExec (0.00s) Signed-off-by: David Crawshaw <crawshaw@tailscale.com>	4 years ago
David Anderson	267531e4f8	wgengine/router: probe better for v6 policy routing support. Previously we disabled v6 support if the disable_policy knob was missing in /proc, but some kernels support policy routing without exposing the toggle. So instead, treat disable_policy absence as a "maybe", and make the direct `ip -6 rule` probing a bit more elaborate to compensate. Fixes #1241.

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
