Brad Fitzpatrick	19189d7018	wgengine/router: add a addrFamily type [linux] In prep for more netlink-ification. Change-Id: I7c34a04001988107dc2583597aa4f26ddb887e91	3 years ago

Brad Fitzpatrick	7c40a5d440	wgengine/router: refactor in prep for Linux netlink-ification Pull out the list of policy routing rules to a data structure now shared between the add & delete paths, but to also be shared by the netlink paths in a future change. Updates #391 Change-Id: I119ab1c246f141d639006c808b61c585c3d67924 Signed-off-by: Brad Fitzpatrick <bradfitz@tailscale.com>	3 years ago
Josh Bleecher Snyder	94fb42d4b2	all: use testingutil.MinAllocsPerRun There are a few remaining uses of testing.AllocsPerRun: Two in which we only log the number of allocations, and one in which dynamically calculate the allocations target based on a different AllocsPerRun run. This also allows us to tighten the "no allocs" test in wgengine/filter. Signed-off-by: Josh Bleecher Snyder <josh@tailscale.com>	3 years ago
Josh Bleecher Snyder	1df865a580	wgengine/magicsock: allow even fewer allocs per UDP receive We improved things again for Go 1.18. Lock that in. Signed-off-by: Josh Bleecher Snyder <josh@tailscale.com>	3 years ago
Josh Bleecher Snyder	c1d377078d	wgengine/magicsock: use testingutil.MinAllocsPerRun This speeds up and deflakes the test. Fixes #2826 (again) Signed-off-by: Josh Bleecher Snyder <josh@tailscale.com>	3 years ago
Brad Fitzpatrick	aad46bd9ff	wgengine/router: stop cleaning up old dev rules on Linux Anybody using that one old, unreleased version of Tailscale from over a year ago should've rebooted their machine by now to get various non-Tailscale security updates. :) Change-Id: If9e043cb008b20fcd6ddfd03756b3b23a9d7aeb5 Signed-off-by: Brad Fitzpatrick <bradfitz@tailscale.com>	3 years ago

Brad Fitzpatrick	b0b0a80318	net/netcheck: implement netcheck for js/wasm clients And the derper change to add a CORS endpoint for latency measurement. And a little magicsock change to cut down some log spam on js/wasm.

Maisem Ali	85fa1b0d61	wgengine: fail NewUserspaceEngine if wireguard device doesn't come up Just something I ran across while debugging an unrelated failure. This is not in response to any bug/issue. Signed-off-by: Maisem Ali <maisem@tailscale.com>	3 years ago
David Crawshaw	0b62f26349	magicsock: remove test data race Speculative, I haven't been able to replicate it locally. Fixes #3156 Signed-off-by: David Crawshaw <crawshaw@tailscale.com>	3 years ago

Brad Fitzpatrick	e25afc6656	wgengine/magicsock: don't try to determine endpoints on js/wasm Avoid netcheck, LocalAddr, etc. Updates #3157 Change-Id: Ibc875c787c0e101b8076e64833f4fcc809372815 Signed-off-by: Brad Fitzpatrick <bradfitz@tailscale.com>	3 years ago
Brad Fitzpatrick	6cb2705833	wgengine/magicsock: don't run UDP listeners on js/wasm Be DERP-only for now. (WebRTC can come later :)) Updates #3157 Change-Id: I56ebb3d914e37e8f4ab651306fd705b817ca381c Signed-off-by: Brad Fitzpatrick <bradfitz@tailscale.com>	3 years ago

David Anderson	b956139b0c	wgengine/magicsock: track IP<>node mappings without relying on discokeys. Updates #3088. Signed-off-by: David Anderson <danderson@tailscale.com>	3 years ago
Brad Fitzpatrick	7a243ae5b1	wgengine/magicsock: finish TODO to speed up peerMap.forEachEndpointWithDiscoKey Now that peerMap tracks the set of nodes for a DiscoKey.

Brad Fitzpatrick	11fdb14c53	wgengine/magicsock: don't check always-non-nil endpoint for nil-ness Continuation of `2aa5df7ac1`, remove nil check because it can never be nil. (It previously was able to be nil.) Change-Id: I59cd9ad611dbdcbfba680ed9b22e841b00c9d5e6 Signed-off-by: Brad Fitzpatrick <bradfitz@tailscale.com>	3 years ago
David Anderson	e7eb46bced	wgengine/magicsock: add an explicit else branch to peerMap update. Clarifies that the replace+delete of peerinfo data is only when peerInfo already exists. Signed-off-by: David Anderson <danderson@tailscale.com>	3 years ago
Maisem Ali	53199738fb	wgengine: don't try to delete legacy netfilter rules on synology. Signed-off-by: Maisem Ali <maisem@tailscale.com>	3 years ago

Brad Fitzpatrick	a6d02dc122	wgengine/magicsock: track which NodeKey each DiscoKey was last for This adds new fields (currently unused) to discoInfo to track what the last verified (unambiguous) NodeKey a DiscoKey last mapped to, and when. Then on CallMeMaybe, Pong and on most Pings, we update the mapping from DiscoKey to the current NodeKey for that DiscoKey.

Brad Fitzpatrick	c759fcc7d3	wgengine/magicsock: fix data race with sync.Pool in error+logging path Fixes #3122 Change-Id: Ib52e84f9bd5813d6cf2e80ce5b2296912a48e064 Signed-off-by: Brad Fitzpatrick <bradfitz@tailscale.com>	3 years ago
Brad Fitzpatrick	75a7779b42	disco, wgengine/magicsock: send self node key in disco pings This lets clients quickly (sub-millisecond within a local LAN) map from an ambiguous disco key to a node key without waiting for a CallMeMaybe (over relatively high latency DERP). Updates #3088 Signed-off-by: Brad Fitzpatrick <bradfitz@tailscale.com>	3 years ago
Joe Tsai	9af27ba829	cmd/cloner: mangle "go:generate" in cloner.go The "go generate" command blindly looks for "//go:generate" anywhere in the file regardless of whether it is truly a comment. Prevent this false positive in cloner.go by mangling the string to look less like "//go:generate". Signed-off-by: Joe Tsai <joetsai@digital-static.net>	3 years ago
Denton Gentry	def650b3e8	wgengine/magicsock: don't Rebind after STUN error if closed. https://github.com/tailscale/tailscale/pull/3014 added a rebind on STUN failure, which means there can now be a tailscale.com/wgengine/magicsock.(*RebindingUDPConn).ReadFromNetaddr in progress at the end of the test waiting for a STUN response which will never arrive. This causes a test flake due to the resource leak in those cases where the Conn decided to rebind. For whatever reason, it mostly flakes with Windows. If the Conn is closed, don't Rebind after a send error. Signed-off-by: Denton Gentry <dgentry@tailscale.com>	3 years ago
Brad Fitzpatrick	f55c2bccf5	wgengine/magicsock: don't call setAddrToDiscoLocked on DERP ping Signed-off-by: Brad Fitzpatrick <bradfitz@tailscale.com>	3 years ago
Brad Fitzpatrick	569f70abfd	wgengine/magicsock: finish some renamings of discoEndpoint to endpoint Renames only; continuation of earlier `8049063d35` These kept confusing me while working on #3088 Signed-off-by: Brad Fitzpatrick <bradfitz@tailscale.com>	3 years ago
Brad Fitzpatrick	695df497ba	wgengine/magicsock: delete peerMap.endpointForDiscoKey, remove remaining caller The one remaining caller of peerMap.endpointForDiscoKey was making the improper assumption that there's exactly 1 node with a given DiscoKey in the network. That was the cause of #3088. Now that all the other callers have been updated to not use endpointForDiscoKey, there's no need to try to keep maintaining that prone-to-misuse index. Updates #3088 Signed-off-by: Brad Fitzpatrick <bradfitz@tailscale.com>	3 years ago
Brad Fitzpatrick	04fd94acd6	wgengine/magicsock: remove endpointForDiscoKey call from handleDiscoMessage A DiscoKey maps 1:n to endpoints. When we get a disco pong, we don't necessarily know which endpoint sent it to us. Ask them all. There will only usually be 1 (and in rare circumstances 2). So it's easier to ask all two rather than building new maps from the random ping TxID to its endpoint. Updates #3088 Signed-off-by: Brad Fitzpatrick <bradfitz@tailscale.com>	3 years ago
Brad Fitzpatrick	151b4415ca	wgengine/magicsock: remove endpoint parameter from handlePingLocked We can reply to a ping without knowing which exact node it's from. As long as it's in our netmap, it's safe to reply. If there's more than one node with that discokey, it doesn't matter who we're relpying to. Updates #3088 Signed-off-by: Brad Fitzpatrick <bradfitz@tailscale.com>	3 years ago
Brad Fitzpatrick	d86081f353	wgengine/magicsock: add new discoInfo type for DiscoKey state, move some fields As more prep for removing the false assumption that you're able to map from DiscoKey to a single peer, move the lastPingFrom and lastPingTime fields from the endpoint type to a new discoInfo type, effectively upgrading the old sharedDiscoKey map (which only held a *[32]byte nacl precomputed key as its value) to discoInfo which then includes that naclbox key. Then start plumbing it into handlePing in prep for removing the need for handlePing to take an endpoint parameter. Updates #3088 Signed-off-by: Brad Fitzpatrick <bradfitz@tailscale.com>	3 years ago
Brad Fitzpatrick	e5779f019e	wgengine/magicsock: move temporary endpoint lookup later, add TODO to remove Updates #3088 Signed-off-by: Brad Fitzpatrick <bradfitz@tailscale.com>	3 years ago
