Brad Fitzpatrick	dda03a911e	wgengine/monitor: change API to permit multiple independent callbakcks Currently it assumes exactly 1 registered callback. This changes it to support 0, 1, or more than 1. This is a step towards plumbing wgengine/monitor into more places (and moving some of wgengine's interface state fetching into monitor in a later step) Signed-off-by: Brad Fitzpatrick <bradfitz@tailscale.com>	4 years ago
David Anderson	6e42430ad8	wgengine/monitor: don't log any single-IP routes added to the tailscale table. Signed-off-by: David Anderson <danderson@tailscale.com>	4 years ago
David Anderson	df5adb2e23	wgengine/monitor: on linux, also monitor for IPv6 changes. Signed-off-by: David Anderson <danderson@tailscale.com>	4 years ago
Brad Fitzpatrick	36189e2704	wgengine/monitor: prevent shutdown hang in darwin link monitor	4 years ago
Brad Fitzpatrick	4f7d60ad42	wgengine/monitor: add a darwin implementation for tailscaled mode Tangentially related to #987, #177, #594, #925, #505 Motivated by rebooting a launchd-controlled tailscaled and it going into SetNetworkUp(false) mode immediately because there really is no network up at system boot, but then it got stuck in that paused state forever, without a monitor implementation.	4 years ago
Alex Brainman	9985b3f1ed	wgengine/monitor: close closeHandle `eccc167` introduced closeHandle which opened the handle, but never closed it. Windows handles should be closed. Updates #921 Signed-off-by: Alex Brainman <alex.brainman@gmail.com>	4 years ago
Matt Layher	bfbd6b9241	go.mod: bump github.com/mdlayher/netlink to v1.2.0 Signed-off-by: Matt Layher <mdlayher@gmail.com>	4 years ago
Brad Fitzpatrick	eccc167733	wgengine/monitor: fix memory corruption in Windows implementation I used the Windows APIs wrong previously, but it had worked just enough. Updates #921 Signed-off-by: Brad Fitzpatrick <bradfitz@tailscale.com>	4 years ago
Brad Fitzpatrick	22c462bd91	wgengine/monitor: fix copy/paste-o to actually monitor route changes Due to a copy/paste-o, we were monitoring address changes twice, and not monitoring route changes at all. Verified with 'tailscale debug --monitor' that this actually works now (while running 'route add 10.3.0.0 mask 255.255.0.0 10.0.0.1' and 'route delete (same)' back and forth in cmd.exe) In practice route changes are accompanied by address changes and this doesn't fix any known issues. I just noticed this while reading this code again. But at least the code does what it was trying to do now.	4 years ago
Brad Fitzpatrick	24d1a38e81	wgengine/monitor: add a poller to the Windows link change monitor The poller is slow by default, but speeds up for a bit after a network change, in case WPAD/PAC files are still loading.	4 years ago

Brad Fitzpatrick	ce1b52bb71	wgengine/monitor: fix other potential crashes on Linux Never return "nil, nil" anymore. The caller expected a usable interface now. I missed some of these earlier. Also, handle address deletion now. Updates #532	4 years ago

Brad Fitzpatrick	023df9239e	Move linkstate boring change filtering to magicsock So we can at least re-STUN on boring updates. Signed-off-by: Brad Fitzpatrick <bradfitz@tailscale.com>	5 years ago
Brad Fitzpatrick	5c1e443d34	wgengine/monitor: don't call LinkChange when interfaces look unchanged Basically, don't trust the OS-level link monitor to only tell you interesting things. Sanity check it. Also, move the interfaces package into the net directory now that we have it.	5 years ago
Tobias Klauser	4d09316f9a	wgengine/monitor: use RTMGRP_* consts from x/sys/unix Bump golang.org/x/sys/unix to get the RTMGRP_* consts and use them. Signed-off-by: Tobias Klauser <tklauser@distanz.ch>	5 years ago

Brad Fitzpatrick	7f5e3febe5	wgengine: move link monitor to be owned by the engine, not the router And make the monitor package portable with no-op implementations on unsupported operating systems. Signed-off-by: Brad Fitzpatrick <bradfitz@tailscale.com>	5 years ago
Brad Fitzpatrick	79295b1138	wgengine: simplify, change some signatures * make RouterGen return an error, not take both tunname and tundev * also remove RouteGen taking a wireguard/device.Device; currently unused * remove derp parameter (it'll work differently) * unexport NewUserspaceRouter in per-OS impls, add documented wrapper Signed-off-by: Brad Fitzpatrick <bradfitz@tailscale.com>	5 years ago
