Percy Wegmann	f9949cde8b	client/tailscale,cmd/{cli,get-authkey,k8s-operator}: set distinct User-Agents ... This helps better distinguish what is generating activity to the Tailscale public API. Updates tailscale/corp#23838 Signed-off-by: Percy Wegmann <percy@tailscale.com>	3 weeks ago
Kristoffer Dalby	0e0e53d3b3	util/usermetrics: make usermetrics non-global ... this commit changes usermetrics to be non-global, this is a building block for correct metrics if a go process runs multiple tsnets or in tests.

Brad Fitzpatrick	0a2e5afb26	tsnet: remove old package doc experimental warning ... It was scaring people. It's been pretty stable for quite some time now and we're unlikely to change the API and break people at this point. We might, but have been trying not to.

Maisem Ali	7b193de6b9	tsnet: return net.Listener from s.listen ... A `*listener` implements net.Listener which breaks a test in another repo. Regressed in 42cfbf427c. Updates #12182 Signed-off-by: Maisem Ali <maisem@tailscale.com>	5 months ago
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>	6 months ago

Charlotte Brandhorst-Satzkorn	93618a3518	tailscale: update tailfs functions and vars to use drive naming (#11597) ...

Joe Tsai	85febda86d	all: use zstdframe where sensible (#11491) ... Use the zstdframe package where sensible instead of plumbing around our own zstd.Encoder just for stateless operations. This causes logtail to have a dependency on zstd, but that's arguably okay since zstd support is implicit to the protocol between a client and the logging service. Also, virtually every caller to logger.NewLogger was manually setting up a zstd.Encoder anyways, meaning that zstd was functionally always a dependency.

Percy Wegmann	993acf4475	tailfs: initial implementation ... Add a WebDAV-based folder sharing mechanism that is exposed to local clients at 100.100.100.100:8080 and to remote peers via a new peerapi endpoint at /v0/tailfs.

Andrew Dunham	46bdbb3878	cmd/tailscaled, tsnet: don't return an interface containing a nil pointer ... This tripped me up when I was testing something and wrote: if conn != nil { conn.Close() } In netstack mode, when an error occurred we were getting a non-nil error and a non-nil interface that contained a nil pointer. Instead, just return a nil interface value. Updates #cleanup Signed-off-by: Andrew Dunham <andrew@du.nham.ca> Change-Id: Id9ef3dd24529e0e8c53adc60ed914c31fbb10cc4	10 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.

Brad Fitzpatrick	d36a0d42aa	tsnet: check a bit harder for https in Server.ListenFunnel ... This was mostly already fixed already indirectly in earlier commits but add a last second length check to this slice so it can't ever OOB.

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.

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.

Brad Fitzpatrick	926c990a09	types/netmap: start phasing out Addresses, add GetAddresses method ... NetworkMap.Addresses is redundant with the SelfNode.Addresses.

Brad Fitzpatrick	343c0f1031	wgengine{,/netstack}: remove AddNetworkMapCallback from Engine interface ... It had exactly one user: netstack. Just have LocalBackend notify netstack when here's a new netmap instead, simplifying the bloated Engine interface that has grown a bunch of non-Engine-y things.

Brad Fitzpatrick	4e91cf20a8	control/controlknobs, all: add plumbed Knobs type, not global variables ... Previously two tsnet nodes in the same process couldn't have disjoint sets of controlknob settings from control as both would overwrite each other's global variables. This plumbs a new controlknobs.Knobs type around everywhere and hangs the knobs sent by control on that instead.

Mihai Parparita	7330aa593e	all: avoid repeated default interface lookups ... On some platforms (notably macOS and iOS) we look up the default interface to bind outgoing connections to. This is both duplicated work and results in logspam when the default interface is not available (i.e. when a phone has no connectivity, we log an error and thus cause more things that we will try to upload and fail). Fixed by passing around a netmon.Monitor to more places, so that we can use its cached interface state. Fixes #7850 Updates #7621 Signed-off-by: Mihai Parparita <mihai@tailscale.com>	2 years ago
Mihai Parparita	4722f7e322	all: move network monitoring from wgengine/monitor to net/netmon ... We're using it in more and more places, and it's not really specific to our use of Wireguard (and does more just link/interface monitoring). Also removes the separate interface we had for it in sockstats -- it's a small enough package (we already pull in all of its dependencies via other paths) that it's not worth the extra complexity.
