Mihai Parparita	7330aa593e	all: avoid repeated default interface lookups ... On some platforms (notably macOS and iOS) we look up the default interface to bind outgoing connections to. This is both duplicated work and results in logspam when the default interface is not available (i.e. when a phone has no connectivity, we log an error and thus cause more things that we will try to upload and fail). Fixed by passing around a netmon.Monitor to more places, so that we can use its cached interface state. Fixes #7850 Updates #7621 Signed-off-by: Mihai Parparita <mihai@tailscale.com>	2 years 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
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
Josh Bleecher Snyder	758c37b83d	net/netns: thread logf into control functions ... So that darwin can log there without panicking during tests. 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
Brad Fitzpatrick	713c5c9ab1	net/{interfaces,netns}: change which build tag means mac/ios Network/System Extension ... We used to use "redo" for that, but it was pretty vague. Also, fix the build tags broken in interfaces_default_route_test.go from a9745a0b68, moving those Linux-specific tests to interfaces_linux_test.go.

Brad Fitzpatrick	52e24aa966	net/{interfaces,ns}: add tailscaled-mode darwin routing looping prevention ... Fixes #1331 Signed-off-by: Brad Fitzpatrick <bradfitz@tailscale.com>	4 years ago
David Anderson	8f5b52e571	net/netns: add windows support. ... Also remove rebinding logic from the windows router. Magicsock will instead rebind based on link change signals. Signed-off-by: David Anderson <danderson@tailscale.com>	4 years ago
David Anderson	5114df415e	net/netns: set the bypass socket mark on linux. ... This allows tailscaled's own traffic to bypass Tailscale-managed routes, so that things like tailscale-provided default routes don't break tailscaled itself. Progress on #144.
