Anton Tolchanov	9c2ad7086c	net/interfaces: deduplicate route table parsing on Darwin and FreeBSD Signed-off-by: Anton Tolchanov <anton@tailscale.com>	2 years ago
Brad Fitzpatrick	a12aad6b47	all: convert more code to use net/netip directly perl -i -npe 's,netaddr.IPPrefixFrom,netip.PrefixFrom,' $(git grep -l -F netaddr.) perl -i -npe 's,netaddr.IPPortFrom,netip.AddrPortFrom,' $(git grep -l -F netaddr. ) perl -i -npe 's,netaddr.IPPrefix,netip.Prefix,g' $(git grep -l -F netaddr. ) perl -i -npe 's,netaddr.IPPort,netip.AddrPort,g' $(git grep -l -F netaddr. ) perl -i -npe 's,netaddr.IP\b,netip.Addr,g' $(git grep -l -F netaddr. ) perl -i -npe 's,netaddr.IPv6Raw\b,netip.AddrFrom16,g' $(git grep -l -F netaddr. ) goimports -w . Then delete some stuff from the net/netaddr shim package which is no longer neeed.

Brad Fitzpatrick	7eaf5e509f	net/netaddr: start migrating to net/netip via new netaddr adapter package Updates #5162 Change-Id: Id7bdec303b25471f69d542f8ce43805328d56c12 Signed-off-by: Brad Fitzpatrick <bradfitz@tailscale.com>	2 years ago
Brad Fitzpatrick	04c2c5bd80	net/interfaces: define DefaultRouteInterface and State.DefaultRouteInterface It was pretty ill-defined before and mostly for logging. But I wanted to start depending on it, so define what it is and make Windows match the other operating systems, without losing the log output we had before. (and add tests for that) Change-Id: I0fbbba1cfc67a265d09dd6cb738b73f0f6005247 Signed-off-by: Brad Fitzpatrick <bradfitz@tailscale.com>	3 years ago
Brad Fitzpatrick	3173c5a65c	net/interface: remove darwin fetchRoutingTable workaround Fixed upstream. Bump dep. Updates #1345 Signed-off-by: Brad Fitzpatrick <bradfitz@tailscale.com>	4 years ago
Brad Fitzpatrick	e41075dd4a	net/interfaces: work around race fetching routing table Fixes #1345 Updates golang/go#45736 Signed-off-by: Brad Fitzpatrick <bradfitz@tailscale.com>	4 years ago
Brad Fitzpatrick	974be2ec5c	net/interfaces: rewrite the darwin likelyHomeRouterIP from C to Go We basically already had the RIB-parsing Go code for this in both net/interfaces and wgengine/monitor, for other reasons. Fixes #1426 Fixes #1471 Signed-off-by: Brad Fitzpatrick <bradfitz@tailscale.com>	4 years ago
Brad Fitzpatrick	8a55d463c8	net/interfaces: merge darwin files for DefaultRouteInterface in sandbox DefaultRouteInterface was previously guarded by build tags such that it was only accessible to tailscaled-on-macos, but there was no reason for that. It runs fine in the sandbox and gives better default info, so merge its file into interfaces_darwin.go. Signed-off-by: Brad Fitzpatrick <bradfitz@tailscale.com>	4 years ago
Josh Bleecher Snyder	a6cad71fb2	go.mod: upgrade staticcheck to 0.1.0 Also run go.mod and fix some staticcheck warnings. Signed-off-by: Josh Bleecher Snyder <josh@tailscale.com>	4 years ago
Josh Bleecher Snyder	1ebbaaaebb	net/interfaces: make syscall and netstat agree when multiple gateways are present likelyHomeRouterIPDarwinSyscall iterates through the list of routes, looking for a private gateway, returning the first one it finds. likelyHomeRouterIPDarwinExec does the same thing, except that it returns the last one it finds. As a result, when there are multiple gateways, TestLikelyHomeRouterIPSyscallExec fails. (At least, I think that that is what is happening; I am going inferring from observed behavior.)

Josh Bleecher Snyder	a16a793605	net/interfaces: use syscalls to find private gateway IP address iOS doesn't let you run subprocesses, which means we can't use netstat to get routing information. Instead, use syscalls and grub around in the results. We keep the old netstat version around, both for use in non-cgo builds, and for use testing the syscall-based version. Note that iOS doesn't ship route.h, so we include a copy here from the macOS 10.15 SDK (which is itself unchanged from the 10.14 SDK). I have tested manually that this yields the correct gateway IP address on my own macOS and iOS devices. More coverage would be most welcome.

Brad Fitzpatrick	c253d4f948	net/interfaces: don't try to fork on iOS in likelyHomeRouterIPDarwin No subprocesses allowed on iOS. Will need to do this differently later.	4 years ago
Brad Fitzpatrick	32156330a8	net/interfaces: add func LikelyHomeRouterIP For discovering where we might direct NAT-PMP/PCP/UPnP queries at in the future.	4 years ago
