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

Andrew Dunham	2703d6916f	net/netns: add functionality to bind outgoing sockets based on route table ... When turned on via environment variable (off by default), this will use the BSD routing APIs to query what interface index a socket should be bound to, rather than binding to the default interface in all cases.

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
