Mihai Parparita	62f4df3257	net/interfaces, net/netns: add node attributes to control default interface getting and binding With #6566 we started to more aggressively bind to the default interface on Darwin. We are seeing some reports of the wrong cellular interface being chosen on iOS. To help with the investigation, this adds to knobs to control the behavior changes: - CapabilityDebugDisableAlternateDefaultRouteInterface disables the alternate function that we use to get the default interface on macOS and iOS (implemented in tailscale/corp#8201). We still log what it would have returned so we can see if it gets things wrong. - CapabilityDebugDisableBindConnToInterface is a bigger hammer that disables binding of connections to the default interface altogether.

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>	1 year ago
Jordan Whited	ea5ee6f87c	all: update golang.zx2c4.com/wireguard to github.com/tailscale/wireguard-go (#6692 ) This is temporary while we work to upstream performance work in https://github.com/WireGuard/wireguard-go/pull/64. A replace directive is less ideal as it breaks dependent code without duplication of the directive. Signed-off-by: Jordan Whited <jordan@tailscale.com>	1 year ago
Mihai Parparita	79f3a5d753	net/netns, net/interfaces: explicitly bind sockets to the default interface on all Darwin variants We were previously only doing this for tailscaled-on-Darwin, but it also appears to help on iOS. Otherwise, when we rebind magicsock UDP connections after a cellular -> WiFi interface change they still keep using cellular one. To do this correctly when using exit nodes, we need to exclude the Tailscale interface when getting the default route, otherwise packets cannot leave the tunnel. There are native macOS/iOS APIs that we can use to do this, so we allow those clients to override the implementation of DefaultRouteInterfaceIndex. Updates #6565, may also help with #5156 Signed-off-by: Mihai Parparita <mihai@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

Anton Tolchanov	d499afac78	net/interfaces: improve default route detection Instead of treating any interface with a non-ifscope route as a potential default gateway, now verify that a given route is actually a default route (0.0.0.0/0 or ::/0).

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.
