Marwan Sulaiman	e32e5c0d0c	portlist: add Poller.IncludeLocalhost option This PR parameterizes receiving loopback updates from the portlist package. Callers can now include services bound to localhost if they want. Note that this option is off by default still. Fixes #8171 Signed-off-by: Marwan Sulaiman <marwan@tailscale.com>	1 year 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>	2 years ago
Maisem Ali	b5299d7d0e	portlist: wait for lsof cmd to exit We were leaking processes otherwise. Co-authored-by: Mihai Parparita <mihai@tailscale.com> Signed-off-by: Maisem Ali <maisem@tailscale.com>	2 years ago
Brad Fitzpatrick	21ef7e5c35	portlist: add macOS osImpl, finish migration to new style Previously: * `036f70b7b4` for linux * `35bee36549` for windows This does macOS. And removes all the compat code for the old style. (e.g. iOS, js are no longer mentioned; all platforms without implementations just default to not doing anything) One possible regression is that platforms without explicit implementations previously tried to do the "netstat -na" style to get open ports (but not process names). Maybe that worked on FreeBSD and OpenBSD previously, but nobody ever really tested it. And it was kinda useless without associated process names. So better off removing those for now until they get a good implementation. Signed-off-by: Brad Fitzpatrick <bradfitz@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,,' $(git grep -l -F '+build') Signed-off-by: Brad Fitzpatrick <bradfitz@tailscale.com>	2 years ago
Brad Fitzpatrick	46ce80758d	portlist: update some internals to use append-style APIs In prep for reducing garbage, being able to reuse memory. So far this doesn't actually reuse much. This is just changing signatures around. But some improvement in any case: bradfitz@tsdev:~/src/tailscale.com$ ~/go/bin/benchstat before after name old time/op new time/op delta GetList-8 11.8ms ± 9% 9.9ms ± 3% -15.98% (p=0.000 n=10+10) name old alloc/op new alloc/op delta GetList-8 99.5kB ± 2% 91.9kB ± 0% -7.62% (p=0.000 n=9+9) name old allocs/op new allocs/op delta GetList-8 3.05k ± 1% 2.93k ± 0% -3.83% (p=0.000 n=8+9) More later, once parsers can reuse strings from previous parses.

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. Signed-off-by: Josh Bleecher Snyder <josh@tailscale.com>	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. 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

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 Signed-off-by: moncho <50428+moncho@users.noreply.github.com>	4 years ago
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: `8c1db77a92 (diff-72072cbd53a7240debad8aa506ff7ec795f9cfac7322e779f9bac29a4d0d0bd4)`	4 years ago
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.	5 years ago
