Updates #15160 Signed-off-by: David Anderson <dave@tailscale.com>
2024-04-28net/netmon, add: add netmon.State type alias of interfaces.StateBrad Fitzpatrick1-2/+1
... in prep for merging the net/interfaces package into net/netmon. This is a no-op change that updates a bunch of the API signatures ahead of a future change to actually move things (and remove the type alias) Updates tailscale/corp#10910 Updates tailscale/corp#18960 Updates #7967 Updates #3299 Change-Id: I477613388f09389214db0d77ccf24a65bff2199c Signed-off-by: Brad Fitzpatrick <bradfitz@tailscale.com>
2024-04-25tsd, ipnlocal, etc: add tsd.System.HealthTracker, start some plumbingBrad Fitzpatrick1-0/+4
This adds a health.Tracker to tsd.System, accessible via a new tsd.System.HealthTracker method. In the future, that new method will return a tsd.System-specific HealthTracker, so multiple tsnet.Servers in the same process are isolated. For now, though, it just always returns the temporary health.Global value. That permits incremental plumbing over a number of changes. When the second to last health.Global reference is gone, then the tsd.System.HealthTracker implementation can return a private Tracker. The primary plumbing this does is adding it to LocalBackend and its dozen and change health calls. A few misc other callers are also plumbed. Subsequent changes will flesh out other parts of the tree (magicsock, controlclient, etc).

2023-04-20all: avoid repeated default interface lookupsMihai Parparita1-2/+2
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>
2023-04-20all: move network monitoring from wgengine/monitor to net/netmonMihai Parparita1-5/+5
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.

2023-03-03cmd/tailscale, cmd/tailscaled: move portmapper debugging into tailscale CLIAndrew Dunham1-97/+1
The debug flag on tailscaled isn't available in the macOS App Store build, since we don't have a tailscaled binary; move it to the 'tailscale debug' CLI that is available on all platforms instead, accessed over LocalAPI. Updates #7377 Signed-off-by: Andrew Dunham <andrew@du.nham.ca> Change-Id: I47bffe4461e036fab577c2e51e173f4003592ff7
2023-01-27all: update copyright and license headersWill Norris1-3/+2
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>
2022-11-04all: remove old +build tagsBrad Fitzpatrick1-1/+0
The //go:build syntax was introduced in Go 1.17: https://go.dev/doc/go1.17#build-lines gofmt has kept the +build and go:build lines in sync since then, but enough time has passed. Time to remove them. Done with: perl -i -npe 's,^// \+build.*\n,,' $(git grep -l -F '+build') Signed-off-by: Brad Fitzpatrick <bradfitz@tailscale.com>

2022-09-15refactor: move from io/ioutil to io and os packagesEng Zer Jun1-2/+1
The io/ioutil package has been deprecated as of Go 1.16 [1]. This commit replaces the existing io/ioutil functions with their new definitions in io and os packages. Reference: https://golang.org/doc/go1.16#ioutil Signed-off-by: Eng Zer Jun <engzerjun@gmail.com>

2022-07-25all: convert more code to use net/netip directlyBrad Fitzpatrick1-2/+1
perl -i -npe 's,netaddr.IPPrefixFrom,netip.PrefixFrom,' $(git grep -l -F netaddr.) perl -i -npe 's,netaddr.IPPortFrom,netip.AddrPortFrom,' $(git grep -l -F netaddr. ) perl -i -npe 's,netaddr.IPPrefix,netip.Prefix,g' $(git grep -l -F netaddr. ) perl -i -npe 's,netaddr.IPPort,netip.AddrPort,g' $(git grep -l -F netaddr. ) perl -i -npe 's,netaddr.IP\b,netip.Addr,g' $(git grep -l -F netaddr. ) perl -i -npe 's,netaddr.IPv6Raw\b,netip.AddrFrom16,g' $(git grep -l -F netaddr. ) goimports -w . Then delete some stuff from the net/netaddr shim package which is no longer neeed.

2022-07-25all: use various net/netip parse funcs directlyBrad Fitzpatrick1-2/+3
Mechanical change with perl+goimports. Changed {Must,}Parse{IP,IPPrefix,IPPort} to their netip variants, then goimports -d . Finally, removed the net/netaddr wrappers, to prevent future use.

2022-03-18cmd/tailscaled: make build fail nicely on older Go versionsBrad Fitzpatrick1-0/+3
Due to a bug in Go (golang/go#51778), cmd/go doesn't warn about your Go version being older than the go.mod's declared Go version in that case that package loading fails before the build starts, such as when you use packages that are only in the current version of Go, like our use of net/netip. This change works around that Go bug by adding build tags and a pre-Go1.18-only file that will cause Go 1.17 and earlier to fail like: $ ~/sdk/go1.17/bin/go install ./cmd/tailscaled # tailscale.com/cmd/tailscaled ./required_version.go:11:2: undefined: you_need_Go_1_18_to_compile_Tailscale note: module requires Go 1.18 Change-Id: I39f5820de646703e19dde448dd86a7022252f75c Signed-off-by: Brad Fitzpatrick <bradfitz@tailscale.com>
2022-01-24envknob: add new package for all the strconv.ParseBool(os.Getenv(..))Brad Fitzpatrick1-1/+2
A new package can also later record/report which knobs are checked and set. It also makes the code cleaner & easier to grep for env knobs. Change-Id: Id8a123ab7539f1fadbd27e0cbeac79c2e4f09751 Signed-off-by: Brad Fitzpatrick <bradfitz@tailscale.com>

2021-09-22cmd/tailscaled: appease a security scannerBrad Fitzpatrick1-1/+8
There are two reasons this can't ever go to actual logs, but rewrite it to make it happy. Fixes tailscale/corp#2695 Signed-off-by: Brad Fitzpatrick <bradfitz@tailscale.com>
2021-08-26cmd/tailscaled: add debug flag to print interfaces just onceBrad Fitzpatrick1-3/+13
It previously only had a polling monitor mode. Signed-off-by: Brad Fitzpatrick <bradfitz@tailscale.com>
2021-08-04net/portmapper: fix UPnP probing, work against all portsBrad Fitzpatrick1-7/+23
Prior to Tailscale 1.12 it detected UPnP on any port. Starting with Tailscale 1.11.x, it stopped detecting UPnP on all ports. Then start plumbing its discovered Location header port number to the code that was assuming port 5000. Fixes #2109 Signed-off-by: Brad Fitzpatrick <bradfitz@tailscale.com>
2021-08-03cmd/tailscaled: let portmap debug mode have an gateway/IP override knobBrad Fitzpatrick1-1/+21
For testing pfSense clients "behind" pfSense on Digital Ocean where the main interface still exists. This is easier for debugging. Signed-off-by: Brad Fitzpatrick <bradfitz@tailscale.com>

2021-06-28cmd/tailscale: make netcheck use active DERP map, delete static copyjulianknodt1-2/+23
After allowing for custom DERP maps, it's convenient to be able to see their latency in netcheck. This adds a query to the local tailscaled for the current DERPMap. Updates #1264 Signed-off-by: julianknodt <julianknodt@gmail.com>
2021-03-25Revert "cmd/tailscaled: split package main into main shim + package"Brad Fitzpatrick1-0/+172
This reverts commit b81bd8025b71f35295201d18011855c1cfae630e. Not needed. See: https://github.com/golang/go/wiki/Modules#how-can-i-track-tool-dependencies-for-a-module
2021-03-24cmd/tailscaled: split package main into main shim + packageBrad Fitzpatrick1-172/+0
So we can empty import the guts of cmd/tailscaled from another module for go mod tidy reasons. Signed-off-by: Brad Fitzpatrick <bradfitz@tailscale.com>
2021-03-08cmd/tailscaled: fix monitor debug tool's outputBrad Fitzpatrick1-1/+1
Logic was backwards, introduced in earlier monitor refactoring last week in e3df29d488f5ce50e. Signed-off-by: Brad Fitzpatrick <bradfitz@tailscale.com>
2021-03-01wgengine{,/monitor}: move interface state fetching/comparing to monitorBrad Fitzpatrick1-10/+9
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 14dc79013754fe we just do the same from Go) Signed-off-by: Brad Fitzpatrick <bradfitz@tailscale.com>
2021-02-27wgengine/monitor: change API to permit multiple independent callbakcksBrad Fitzpatrick1-4/+5
Currently it assumes exactly 1 registered callback. This changes it to support 0, 1, or more than 1. This is a step towards plumbing wgengine/monitor into more places (and moving some of wgengine's interface state fetching into monitor in a later step) Signed-off-by: Brad Fitzpatrick <bradfitz@tailscale.com>
2021-02-14cmd/tailscaled: fix up install-system-daemon on darwin, add uninstall tooBrad Fitzpatrick1-0/+2
Tangentially related to #987, #177, #594, #925, #505
2021-02-04cmd/tailscale{,d}: move debug subcommand to tailscaledBrad Fitzpatrick1-0/+170
Work on reducing the size of the tailscale binary, which is currently pulling in most of the same code as tailscaled. Updates #1181
