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
Brad Fitzpatrick	da8def8e13	all: remove old +build tags ... 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>	2 years ago
Maisem Ali	8e40bfc6ea	wgengine/monitor: ignore OS-specific uninteresting interfaces ... Currently we ignore these interfaces in the darwin osMon but then would consider it interesting when checking if anything had changed. Signed-off-by: Maisem Ali <maisem@tailscale.com>	3 years ago
Todd Neal	eeccbccd08	support running in a FreeBSD jail ... Since devd apparently can't be made to work in a FreeBSD jail fall back to polling. Fixes tailscale#2858 Signed-off-by: Todd Neal <todd@tneal.org>	3 years ago
Josh Bleecher Snyder	ad5e04249b	wgengine/monitor: ignore adding/removing uninteresting IPs ... One of the most common "unexpected" log lines is: "network state changed, but stringification didn't" One way that this can occur is if an interesting interface (non-Tailscale, has interesting IP address) gains or loses an uninteresting IP address (link local or loopback). The fact that the interface is interesting is enough for EqualFiltered to inspect it. The fact that an IP address changed is enough for EqualFiltered to declare that the interfaces are not equal. But the State.String method reasonably declines to print any uninteresting IP addresses. As a result, the network state appears to have changed, but the stringification did not. The String method is correct; nothing interesting happened. This change fixes this by adding an IP address filter to EqualFiltered in addition to the interface filter. This lets the network monitor ignore the addition/removal of uninteresting IP addresses. Signed-off-by: Josh Bleecher Snyder <josh@tailscale.com>	3 years ago
Josh Bleecher Snyder	a5da4ed981	all: gofmt with Go 1.17 ... This adds "//go:build" lines and tidies up existing "// +build" lines. Signed-off-by: Josh Bleecher Snyder <josh@tailscale.com>	3 years ago
Denton Gentry	3089081349	monitor/polling: reduce Cloud Run polling interval. ... Cloud Run's routes never change at runtime. Don't poll it for route changes very often. Signed-off-by: Denton Gentry <dgentry@tailscale.com>	4 years ago
Denton Gentry	35ab4020c7	wgengine/monitor: Linux fall back to polling ... Google Cloud Run does not implement NETLINK_ROUTE RTMGRP. If initialization of the netlink socket or group membership fails, fall back to a polling implementation. Signed-off-by: Denton Gentry <dgentry@tailscale.com>	4 years ago
