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
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
Denton Gentry	1896bf99d9	netns_linux: No namespace for localhost. ... Connections to a control server or log server on localhost, used in a number of tests, are working right now because the calls to SO_MARK in netns fail for non-root but then we ignore the failure when running in tests. Unfortunately that failure in SO_MARK also affects container environments without CAP_NET_ADMIN, breaking Tailscale connectivity. We're about to fix netns to recognize when SO_MARK doesn't work and use SO_BINDTODEVICE instead. Doing so makes tests fail, as their sockets now BINDTODEVICE of the default route and cannot connect to localhost. Add support to skip namespacing for localhost connections, which Darwin and Windows already do. This is not conditional on running within a test, if you tell tailscaled to connect to localhost it will automatically use a non-namespaced socket to do so.
