Josh Bleecher Snyder a3c5de641b portlist: stop logging stray UDP ports
These "weird" port lines show up in logs frequently.
They're the result of uninteresting races,
and they're not actionable. Remove the noise.

Remove the isLoopbackAddr case to placate staticcheck.

David Anderson bf8556ab86 portlist: fix build tag to build only on macOS, not macOS+iOS. 3 years ago
Josh Bleecher Snyder 6da6d47a83 all: simplify build tags involving iOS
Prior to Go 1.16, iOS used GOOS=darwin,
so we had to distinguish macOS from iOS during GOARCH.

We now require Go 1.16 in our go.mod, so we can simplify.

Josh Bleecher Snyder a5da4ed981 all: gofmt with Go 1.17
This adds "//go:build" lines and tidies up existing "// +build" lines.

moncho e101d8396d portlist, version: update build tags for Go 1.16, Apple M1
Build tags have been updated to build native Apple M1 binaries, existing build
tags for ios have been changed from darwin,arm64 to ios,arm64.

With this change, running go build cmd/tailscale{,d}/tailscale{,d}.go on an Apple
machine with the new processor works and resulting binaries show the expected
architecture, e.g. tailscale: Mach-O 64-bit executable arm64.

Tested using go version go1.16beta1 darwin/arm64.

Updates #943

Brad Fitzpatrick 8f76548fd9 tempfork/osexec: remove old fork of os/exec
This package was a temporary fork of os/exec to fix an EINTR loop
bug that was fixed upstream for Go 1.15 in
8c1db77a92
(https://go-review.googlesource.com/c/go/+/232862), in
src/os/exec_unix.go:

Josh Bleecher Snyder a570c27577 portlist: reduce log spam on macOS
Running tailscaled on my machine yields lots of entries like:

weird: missing {tcp 6060}

parsePortsNetstat is filtering out loopback addresses as uninteresting.
Then addProcesses is surprised to discover these listening ports,
which results in spurious logging.
Teach addProcesses to also ignore loopback addresses.

Brad Fitzpatrick 5bb14c07dc portlist: don't depend on tempfork/osexec on iOS, saves 90KB
This gives us 90KB more of memory on iOS, as it shrinks the
NetworkExtension binary by 90KB.

The netstat binary isn't available in the network extension anyway, so
no point pulling in the osexec package which'll just fail to find
netstat anyway.
