Brad Fitzpatrick	0f64d7f9cc	wgengine: remove a tiny allocation Drop in the bucket compared to the larger issues, but noticed it when looking at pprof.	5 years ago
Brad Fitzpatrick	322499473e	cmd/tailscaled, wgengine, ipn: add /debug/ipn handler with world state Signed-off-by: Brad Fitzpatrick <bradfitz@tailscale.com>	5 years ago
Brad Fitzpatrick	2e420ad8b6	wgengine, wgengine/filter: minor doc, style, performance, locking changes Signed-off-by: Brad Fitzpatrick <bradfitz@tailscale.com>	5 years ago
Avery Pennarun	f53e78e0d5	wgengine: don't lose filter state on filter reconfig. We were abandoning the UDP port LRU every time we got a new packet filter from tailcontrol, which caused return packets to suddenly stop arriving.	5 years ago
David Crawshaw	addbdce296	wgengine, ipn: include number of active DERPs in status Use this when making the ipn state transition from Starting to Running. This way a network of quiet nodes with no active handshaking will still transition to Active. Signed-off-by: David Crawshaw <crawshaw@tailscale.com>	5 years ago
Brad Fitzpatrick	db31550854	wgengine: don't Reconfig on boring link changes Signed-off-by: Brad Fitzpatrick <bradfitz@tailscale.com>	5 years ago
Brad Fitzpatrick	39c0ae1dba	derp/derpmap: new DERP config package, merge netcheck into magicsock more Fixes #153 Updates #162 Updates #163 Signed-off-by: Brad Fitzpatrick <bradfitz@tailscale.com>	5 years ago
David Crawshaw	0f73070a57	wgengine: shut down wireguard on Close This was (presumably) missing from wgengine because the interactions between magicsock and wireguard-go meant that the shutdown never worked. Now those are fixed, actually shut down. Fixes occasional flake in expanded ipn/e2e_test. Signed-off-by: David Crawshaw <crawshaw@tailscale.com>	5 years ago
David Crawshaw	ce7f6b2df1	wgengine: have pinger use all single-IP routes Fixes #139 Signed-off-by: David Crawshaw <crawshaw@tailscale.com>	5 years ago
Brad Fitzpatrick	eac62ec5ff	ipn, wgengine/magicsock: add ipn.Prefs.DisableDERP bool Signed-off-by: Brad Fitzpatrick <bradfitz@tailscale.com>	5 years ago
David Crawshaw	34859f8e7d	wgengine, magicsock: add a CreateBind method Signed-off-by: David Crawshaw <crawshaw@tailscale.com>	5 years ago
Brad Fitzpatrick	b27d4c017a	magicsock, wgengine, ipn, controlclient: plumb regular netchecks to map poll Signed-off-by: Brad Fitzpatrick <bradfitz@tailscale.com>	5 years ago
Brad Fitzpatrick	657f9593ae	Reduce some logspam.	5 years ago
Brad Fitzpatrick	67ede8d6d2	wgengine, magicsock: fix SetPrivateKey data race Updates #112 Signed-off-by: Brad Fitzpatrick <bradfitz@tailscale.com>	5 years ago
Brad Fitzpatrick	19b54d0ae7	wgengine: fix a data race on StatusCallback Updates tailscale/tailscale#112 Signed-off-by: Brad Fitzpatrick <bradfitz@tailscale.com>	5 years ago
David Crawshaw	c576a57067	wgengine: avoid holding any locks during HandshakeDone Because wgLock is held while some wireguard-go methods run, trying to hold wgLock during HandshakeDone potentially creates lock cycles between wgengine and internals of wireguard-go. Arguably wireguard-go should call HandshakeDone in a new goroutine, but until its API promises that, don't make any assumptions here. Maybe for #110.

David Crawshaw	44670d0da9	wgengine: revert wgdev.Close on Close from last commit Causes as-yet-unknown problems in some tests. Signed-off-by: David Crawshaw <crawshaw@tailscale.com>	5 years ago
wardn	9390a3ef55	wgengine: properly clean up freebsd routes and interfaces on close Signed-off-by: wardn <wardn@users.noreply.github.com>	5 years ago
David Crawshaw	7a3be96199	wgengine: add pinger to generate initial spray packets For 3 seconds after a successful handshake, wgengine will send a ping packet every 300ms to its peer. This ensures the spray logic in magicsock has something to spray. Signed-off-by: David Crawshaw <crawshaw@tailscale.com>	5 years ago
David Crawshaw	868cfae84f	wgengine, magicsock: adjust for wireguard-go conn/device package split Signed-off-by: David Crawshaw <crawshaw@tailscale.com>	5 years ago
David Crawshaw	4ebc0fa70f	wgengine: incremental update of peers on network map change This is the first, and easier, part of incremental wireguard-go reconfiguration. It means that a new node appearing on the network does not cause all existing nodes to re-handshake with the other nodes they are talking to. (This code has been running on hello.ipn.dev for a few weeks and peers have successfully reconnected to it through many network map updates.)

David Crawshaw	d0f697ee07	wgengine: update for wgcfg changes Signed-off-by: David Crawshaw <crawshaw@tailscale.com>	5 years ago
Brad Fitzpatrick	e06ca40650	wgengine, magicsock, derp: misc cleanups, docs Signed-off-by: Brad Fitzpatrick <bradfitz@tailscale.com>	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
Brad Fitzpatrick	2896be60db	Move "logger" package to under types, now that we have it. Signed-off-by: Brad Fitzpatrick <bradfitz@tailscale.com>	5 years ago
Brad Fitzpatrick	c773abde77	wgengine: fix nil pointer deref crash from earlier change Fixes #45	5 years ago
