Jonathan Nobels	fa1303d632	net/netmon: swap to swift-derived defaultRoute on macos (#11936) ... Updates tailscale/corp#18960 iOS uses Apple's NetworkMonitor to track the default interface and there's no reason we shouldn't also use this on macOS, for the same reasons noted in the comments for why this change was made on iOS. This eliminates the need to load and parse the routing table when querying the defaultRouter() in almost all cases. A slight modification here (on both platforms) to fallback to the default BSD logic in the unhappy-path rather than making assumptions that may not hold. If netmon is eventually parsing AF_ROUTE and able to give a consistently correct answer for the default interface index, we can fall back to that and eliminate the Swift dependency.

Brad Fitzpatrick	b9adbe2002	net/{interfaces,netmon}, all: merge net/interfaces package into net/netmon ... In prep for most of the package funcs in net/interfaces to become methods in a long-lived netmon.Monitor that can cache things. (Many of the funcs are very heavy to call regularly, whereas the long-lived netmon.Monitor can subscribe to things from the OS and remember answers to questions it's asked regularly later) Updates tailscale/corp#10910 Updates tailscale/corp#18960 Updates #7967 Updates #3299 Change-Id: Ie4e8dedb70136af2d611b990b865a822cd1797e5 Signed-off-by: Brad Fitzpatrick <bradfitz@tailscale.com>	1 month ago
