David Crawshaw	a67b174da1	Revert "magicsock: call RequestStatus when DERP connects" ... Seems to break linux CI builder. Cannot reproduce locally, so attempting a rollback. This reverts commit cd7bc02ab1. Signed-off-by: David Crawshaw <crawshaw@tailscale.com>	4 years ago
David Crawshaw	cd7bc02ab1	magicsock: call RequestStatus when DERP connects ... Without this, a freshly started ipn client will be stuck in the "Starting" state until something triggers a call to RequestStatus. Usually a UI does this, but until then we can sit in this state until poked by an external event, as is evidenced by our e2e tests locking up when DERP is attached. (This only recently became a problem when we enabled lazy handshaking everywhere, otherwise the wireugard tunnel creation would also trigger a RequestStatus.)

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	7841c97af5	wgengine: make lazy wireguard on by default ... It can still be explicitly enabled or disabled via the environment variable, then via control. But the default is to be lazy now.	4 years ago
Dmytro Shynkevych	6c71e5b851	tsdns: copy name when loewrcasing. ... The previous approach modifies name in-place in the request slice to avoid an allocation. This is incorrect: the question section of a DNS request must be copied verbatim, without any such modification. Software may rely on it (we rely on other resolvers doing it it in tsdns/forwarder).

Brad Fitzpatrick	85c3d17b3c	wgengine/magicsock: use disco ping src as a candidate endpoint ... Consider: Hard NAT (A) <---> Hard NAT w/ mapped port (B) If A sends a packet to B's mapped port, A can disco ping B directly, with low latency, without DERP. But B couldn't establish a path back to A and needed to use DERP, despite already logging about A's endpoint and adding a mapping to it for other purposes (the wireguard conn.Endpoint lookup also needed it). This adds the tracking to discoEndpoint too so it'll be used for finding a path back. Fixes tailscale/corp#556 Signed-off-by: Brad Fitzpatrick <bradfitz@tailscale.com>	4 years ago

Brad Fitzpatrick	cff737786e	wgengine/magicsock: fix lazy config deadlock, document more lock ordering ... This removes the atomic bool that tried to track whether we needed to acquire the lock on a future recursive call back into magicsock. Unfortunately that hack doesn't work because we also had a lock ordering issue between magicsock and userspaceEngine (see issue). This documents that too. Fixes #644	4 years ago

If a node is behind a hard NAT and is using an explicit local port number, assume they might've mapped a port and add their public IPv4 address with the local tailscaled's port number as a candidate endpoint.	4 years ago

Brad Fitzpatrick	3e493e0417	wgengine: fix lazy wireguard config bug on sent packet minute+ later ... A comparison operator was backwards. The bad case went: * device A send packet to B at t=1s * B gets added to A's wireguard config * B gets packet (5 minutes pass) * some other activity happens, causing B to expire to be removed from A's network map, since it's been over 5 minutes since sent or received activity * device A sends packet to B at t=5m1s * normally, B would get added back, but the old send time was not zero (we sent earlier!) and the time comparison was backwards, so we never regenerated the wireguard config. This also refactors the code for legibility and moves constants up top, with comments.	4 years ago
