Maisem Ali	42cfbf427c	tsnet,wgengine/netstack: add ListenPacket and tests This adds a new ListenPacket function on tsnet.Server which acts mostly like `net.ListenPacket`. Unlike `Server.Listen`, this requires listening on a specific IP and does not automatically listen on both V4 and V6 addresses of the Server when the IP is unspecified. To test this, it also adds UDP support to tsdial.Dialer.UserDial and plumbs it through the localapi. Then an associated test to make sure the UDP functionality works from both sides.

Maisem Ali	486a423716	tsnet: split user facing and backend logging This adds a new `UserLogf` field to the `Server` struct. When set this any logs generated by Server are logged using `UserLogf` and all spammy backend logs are logged to `Logf`. If it `UserLogf` is unset, we default to `log.Printf` and if `Logf` is unset we discard all the spammy logs. Fixes #12094 Signed-off-by: Maisem Ali <maisem@tailscale.com>	7 months ago

Denton Gentry	67f3b2a525	tsnet: add CapturePcap method for debugging Application code can call the tsnet s.CapturePcap(filename) method to write all packets, sent and received, to a pcap file. The cleartext packets are written, outside the Wireguard tunnel. This is expected to be useful for debugging.

Tom DNetto	3df305b764	tsnet: enable use-cases with non-native IPs by setting ns.ProcessSubnets Terminating traffic to IPs which are not the native IPs of the node requires the netstack subsystem to intercept trafic to an IP it does not consider local. This PR switches on such interception. In addition to supporting such termination, this change will also enable exit nodes and subnet routers when running in userspace mode. DO NOT MERGE until 1.52 is cut. Signed-off-by: Tom DNetto <tom@tailscale.com> Updates: https://github.com/tailscale/corp/issues/15038	1 year ago
Brad Fitzpatrick	e89927de2b	tsnet: fix data race in TestFallbackTCPHandler Fixes #9805 Signed-off-by: Brad Fitzpatrick <bradfitz@tailscale.com>	1 year ago
Tom DNetto	fffafc65d6	tsnet: support registering fallback TCP flow handlers For the app connector use-case, it doesnt make sense to use listeners, because then you would need to register thousands of listeners (for each proto/service/port combo) to handle ranges. Instead, we plumb through the TCPHandlerForFlow abstraction, to avoid using the listeners abstraction that would end up being a bit messy.

James Tucker	ca49b29582	tsnet: reenable TestLoopbackSOCKS5 on Windows This test was either fixed in the intermediate time or mis-flagged during the #7876 triage, but is now passing. Updates #7876 Signed-off-by: James Tucker <jftucker@gmail.com>	2 years ago
James Tucker	bd0c32ca21	tsnet: disable TestLoopbackSOCKS5 on Windows This test is not regularly passing on CI, but seems to pass reliably locally. Needs deeper debugging. Updates #7876 Signed-off-by: James Tucker <jftucker@gmail.com>	2 years ago

Maisem Ali	b4d3e2928b	tsnet: avoid deadlock on close tsnet.Server.Close was calling listener.Close with the server mutex held, but the listener close method tries to grab that mutex, resulting in a deadlock.

Maisem Ali	b0cb39cda1	tsnet: only intercept TCP flows that have listeners Previously, it would accept all TCP connections and then close the ones it did not care about. Make it only ever accept the connections that it cares about. Signed-off-by: Maisem Ali <maisem@tailscale.com>	2 years ago
Denton Gentry	b46c5ae82a	cmd/sniproxy: draw the rest of the DNS owl. Add a DNS server which always responds as its own IP addresses. Additionally add a tsnet TailscaleIPs() function to return the IP addresses, both IPv4 and IPv6.

David Crawshaw	387b68fe11	tsnet: generalize loopback listener to include SOCKS5 Some languages do not give you any useful access to the sockets underlying their networking packages. E.g. java.net.http.HttpClient provides no official access to its dialing logic. ...but everyone supports proxies. So add a SOCKS5 proxy on the listener we are already running. (The function being revamped is very new, I only added it in the last week and it wasn't part of any release, so I believe it is fine to redo its function signature.)

Brad Fitzpatrick	0f4359116e	tsnet: add UDP support to Server.Listen No ListenPacket support yet, but Listen with a udp network type fit easier into netstack's model to start. Then added an example of using it to cmd/sniproxy with a little udp :53 handler. No tests in tsnet yet because we don't have support for dialing over UDP in tsnet yet. When that's done, a new test can test both sides. Updates #5871 Updates #1748 Signed-off-by: Brad Fitzpatrick <bradfitz@tailscale.com>	2 years ago
David Crawshaw	768df4ff7a	tsnet: add a LocalAPI listener on loopback, with basic auth This is for use by LocalAPI clients written in other languages that don't appear to be able to talk HTTP over a socket (e.g. java.net.http.HttpClient).

Will Norris	71029cea2d	all: update copyright and license headers This updates all source files to use a new standard header for copyright and license declaration. Notably, copyright no longer includes a date, and we now use the standard SPDX-License-Identifier header. This commit was done almost entirely mechanically with perl, and then some minimal manual fixes. Updates #6865 Signed-off-by: Will Norris <will@tailscale.com>	2 years ago

Will Norris	3344c3b89b	tsnet: add Server method to listener Allow callers to verify that a net.Listener is a tsnet.listener by type asserting against this Server method, as well as providing access to the underlying Server. This is initially being added to support the caddy integration in caddyserver/caddy#5002. Signed-off-by: Will Norris <will@tailscale.com>	2 years ago
