Brad Fitzpatrick 6b232b5a79 Disable staticcheck for tempfork packages. 5 years ago
Numerous Gophers 3bab226299 Add fork of Go 1.15-dev's crypto/x509
Snapshotted from Go commit 619c7a48a38b28b521591b490fd14ccb7ea5e821
(https://go-review.googlesource.com/c/go/+/229762,
"crypto/x509: add x509omitbundledroots build tag to not embed roots")

With 975c01342a25899962969833d8b2873dc8856a4f
(https://go-review.googlesource.com/c/go/+/220721) removed, because it
depends on other stuff in Go std that doesn't yet exist in a Go
release.

Also, add a subset fork of Go's internal/testenv, for use by x509's tests.

David Crawshaw 5b95aa81ea wgengine: remove IpcSetOperation on LinkChange
This was only done occasionally, but was extremely disruptive
when done and is no longer necessary.

It used to be that when switching links, we had to immediately
generate handshakes to everyone we were communicating with to
punch a hole in any NAT we were talking through. (This ended up
not really working, because in the process we got rid of our
session keys and ended up having a futile conversation for many
seconds.)

Now we have DERP, our link change propogates to the other side
as a new list of endpoints, so they start spraying packets.
We will definitely get one thanks to DERP, which will cause us
to spray, opening any NAT we are behind.

The result is that for good connections, we don't trash session
keys and cause an interruption.

Brad Fitzpatrick 922d9546bf wgengine: don't allocate so much in userspaceEngine.getStatus
It was one of the top garbage producers on my phone.

It's slated to be deleted and replaced anyway, but this helps in the
meantime.

The go.sum changes look scary, but the new dep only adds 240 bytes to
the binary. The go.sum noise is just cmd/go being aggressive in
including a lot of stuff (which is being fixed in Go 1.15, for what I
understand). And I ran a go mod tidy, which added some too. (I had to
write a custom wrapper around go mod tidy because this mod tidy
normally breaks on tailscale.io/control being missing but referenced
in tests)

Brad Fitzpatrick 2776209e49 portlist: don't depend on osexec package on ios, even if it's unused
Continuation of 5bb14c07dc.

The earlier commit provided the space savings (as the linker could see
through that osexec was unused at runtime), but it didn't clean up the
dep graph (from go list -json or godepgraph).

This removes the netstat.go file from the build too, just so the dep list
looks more reasonable.

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.
