Maisem Ali	80ba161c40	wgengine/monitor: do not ignore changes to pdp_ip* ... One current theory (among other things) on battery consumption is that magicsock is resorting to using the IPv6 over LTE even on WiFi. One thing that could explain this is that we do not get link change updates for the LTE modem as we ignore them in this list. This commit makes us not ignore changes to `pdp_ip` as a test.

Maisem Ali	8e40bfc6ea	wgengine/monitor: ignore OS-specific uninteresting interfaces ... Currently we ignore these interfaces in the darwin osMon but then would consider it interesting when checking if anything had changed. Signed-off-by: Maisem Ali <maisem@tailscale.com>	3 years ago
Josh Bleecher Snyder	0868329936	all: use any instead of interface{} ... My favorite part of generics. Signed-off-by: Josh Bleecher Snyder <josh@tailscale.com>	3 years ago

Brad Fitzpatrick	0f90586da8	wgengine/monitor: skip more route messages on darwin ... Should help iOS battery life on NEProvider.wake/skip events with useless route updates that shouldn't cause re-STUNs. Signed-off-by: Brad Fitzpatrick <bradfitz@tailscale.com>	4 years ago
Brad Fitzpatrick	7461dded88	wgengine/monitor: on unsupported platforms, use a polling implementation ... Not great, but lets people working on new ports get going more quickly without having to do everything up front. As the link monitor is getting used more, I felt bad having a useless implementation.

Brad Fitzpatrick	471f0c470a	wgengine/monitor: skip some macOS route updates, fix debounce regression ... Debound was broken way back in 5c1e443d34 and we never noticed. Signed-off-by: Brad Fitzpatrick <bradfitz@tailscale.com>	4 years ago
Brad Fitzpatrick	31721759f3	wgengine/monitor: don't return nil, nil in darwin monitor ... We used to allow that, but now it just crashes. Separately I need to figure out why it got into this path at all, which is #1416. Signed-off-by: Brad Fitzpatrick <bradfitz@tailscale.com>	4 years ago
Brad Fitzpatrick	24fa616e73	wgengine/monitor: make Darwin monitor shut down cleanly, add test ... Don't use os.NewFile or (*os.File).Close on the AF_ROUTE socket. It apparently does weird things to the fd and at least doesn't seem to close it. Just use the unix package. The test doesn't actually fail reliably before the fix, though. It was an attempt. But this fixes the integration tests. Signed-off-by: Brad Fitzpatrick <bradfitz@tailscale.com>	4 years ago
Brad Fitzpatrick	14dc790137	wgengine/monitor: make the darwin link monitor work in the sandbox too ... Previously tailscaled on macOS was running "/sbin/route monitor" as a child process, but child processes aren't allowed in the Network Extension / App Store sandbox. Instead, just do what "/sbin/route monitor" itself does: unix.Socket(unix.AF_ROUTE, unix.SOCK_RAW, 0) and read that. We also parse it now, but don't do anything with the parsed results yet. We will over time, as we have with Linux netlink messages over time. Currently any message is considered a signal to poll and see what changed.
