Joe Tsai	c299a96624	all: apply consistent imports of "json" packages ... This runs: go run ./cmd/jsonimports -update -ignore=tempfork/ which applies the following rules: * Until the Go standard library formally accepts "encoding/json/v2" and "encoding/json/jsontext" into the standard library (i.e., they are no longer considered experimental), we forbid any code from directly importing those packages. Go code should instead import "github.com/go-json-experiment/json" and "github.com/go-json-experiment/json/jsontext". The latter packages contain aliases to the standard library if built on Go 1.25 with the goexperiment.jsonv2 tag specified. * Imports of "encoding/json" or "github.com/go-json-experiment/json/v1" must be explicitly imported under the package name "jsonv1". If both packages need to be imported, then the former should be imported under the package name "jsonv1std". * Imports of "github.com/go-json-experiment/json" must be explicitly imported under the package name "jsonv2". The latter two rules exist to provide clarity when reading code. Without them, it is unclear whether "json.Marshal" refers to v1 or v2. With them, however, it is clear that "jsonv1.Marshal" is calling v1 and that "jsonv2.Marshal" is calling v2.

Andrea Gottardo	90be06bd5b	health: introduce captive-portal-detected Warnable (#12707) ... Updates tailscale/tailscale#1634 This PR introduces a new `captive-portal-detected` Warnable which is set to an unhealthy state whenever a captive portal is detected on the local network, preventing Tailscale from connecting. ipn/ipnlocal: fix captive portal loop shutdown Change-Id: I7cafdbce68463a16260091bcec1741501a070c95 net/captivedetection: fix mutex misuse ipn/ipnlocal: ensure that we don't fail to start the timer Change-Id: I3e43fb19264d793e8707c5031c0898e48e3e7465 Signed-off-by: Andrew Dunham <andrew@du.nham.ca> Signed-off-by: Andrea Gottardo <andrea@gottardo.me>	1 year ago
Andrew Dunham	e33bc64cff	net/dnsfallback: add singleflight to recursive resolver ... This prevents running more than one recursive resolution for the same hostname in parallel, which can use excessive amounts of CPU when called in a tight loop. Additionally, add tests that hit the network (when run with a flag) to test the lookup behaviour.

Mihai Parparita	9a655a1d58	net/dnsfallback: more explicitly pass through logf function ... Redoes the approach from #5550 and #7539 to explicitly pass in the logf function, instead of having global state that can be overridden. Signed-off-by: Mihai Parparita <mihai@tailscale.com>	3 years ago
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>	3 years ago
Andrew Dunham	f52a659076	net/dnsfallback: allow setting log function (#5550) ... This broke a test in corp that enforces we don't use the log package. Signed-off-by: Andrew Dunham <andrew@tailscale.com>	3 years ago
Andrew Dunham	b8596f2a2f	net/dnsfallback: cache most recent DERP map on disk (#5545) ... This is especially helpful as we launch newer DERPs over time, and older clients have progressively out-of-date static DERP maps baked in. After this, as long as the client has successfully connected once, it'll cache the most recent DERP map it knows about.

Brad Fitzpatrick	10d7c2583c	net/dnsfallback: don't depend on derpmap.Prod ... Move derpmap.Prod to a static JSON file (go:generate'd) instead, to make its role explicit. And add a TODO about making dnsfallback use an update-over-time DERP map file instead of a baked-in one. Updates #1264 Signed-off-by: Brad Fitzpatrick <bradfitz@tailscale.com>	5 years ago
