Brad Fitzpatrick	d3d503d997	ipn/ipnlocal: add HTTP/2 h2c server support to peerapi on non-mobile platforms To make ExitDNS cheaper. Might not finish client-side support in December before 1.20, but at least server support can start rolling out ahead of clients being ready for it. Tested with curl against peerapi.

Brad Fitzpatrick	c37af58ea4	net/tsdial: move more weirdo dialing into new tsdial package, plumb Not done yet, but this move more of the outbound dial special casing from random packages into tsdial, which aspires to be the one unified place for all outbound dialing shenanigans. Then this plumbs it all around, so everybody is ultimately holding on to the same dialer. As of this commit, macOS/iOS using an exit node should be able to reach to the exit node's DoH DNS proxy over peerapi, doing the sockopt to stay within the Network Extension. A number of steps remain, including but limited to: * move a bunch more random dialing stuff * make netstack-mode tailscaled be able to use exit node's DNS proxy, teaching tsdial's resolver to use it when an exit node is in use.

Brad Fitzpatrick	d5405c66b7	net/tsdial: start of new package to unify all outbound dialing complexity For now this just deletes the net/socks5/tssocks implementation (and the DNSMap stuff from wgengine/netstack) and moves it into net/tsdial. Then initialize a Dialer early in tailscaled, currently only use for the outbound and SOCKS5 proxies. It will be plumbed more later. Notably, it needs to get down into the DNS forwarder for exit node DNS forwading in netstack mode. But it will also absorb all the peerapi setsockopt and netns Dial and tlsdial complexity too.

Josh Bleecher Snyder	73beaaf360	net/tstun: rate limit "self disco out packet" logging When this happens, it is incredibly noisy in the logs. It accounts for about a third of all remaining "unexpected" log lines from a recent investigation. It's not clear that we know how to fix this, we have a functioning workaround, and we now have a (cheap and efficient) metric for this that we can use for measurements. So reduce the logging to approximately once per minute. Signed-off-by: Josh Bleecher Snyder <josh@tailscale.com>	3 years ago

Brad Fitzpatrick	efb84ca60d	ipn/localapi, cmd/tailscale: add CPU & memory profile support, debug command This was already possible on Linux if you ran tailscaled with --debug (which runs net/http/pprof), but it requires the user have the Go toolchain around. Also, it wasn't possible on macOS, as there's no way to run the IPNExtension with a debug server (it doesn't run tailscaled). And on Windows it's super tedious: beyond what users want to do or what we want to explain. Instead, put it in "tailscale debug" so it works and works the same on all platforms. Then we can ask users to run it when we're debugging something and they can email us the output files. Signed-off-by: Brad Fitzpatrick <bradfitz@tailscale.com>	3 years ago

Aaron Klotz	9ebb5d4205	ipn, paths: ensure that the state directory for Windows has the correct perms ProgramData has a permissive ACL. For us to safely store machine-wide state information, we must set a more restrictive ACL on our state directory. We set the ACL so that only talescaled's user (ie, LocalSystem) and the Administrators group may access our directory. We must include Administrators to ensure that logs continue to be easily accessible; omitting that group would force users to use special tools to log in interactively as LocalSystem, which is not ideal. (Note that the ACL we apply matches the ACL that was used for LocalSystem's AppData\Local). There are two cases where we need to reset perms: One is during migration from the old location to the new. The second case is for clean installations where we are creating the file store for the first time. Updates #2856 Signed-off-by: Aaron Klotz <aaron@tailscale.com>	3 years ago

Joe Tsai	d145c594ad	util/deephash: improve cycle detection (#2470 ) The previous algorithm used a map of all visited pointers. The strength of this approach is that it quickly prunes any nodes that we have ever visited before. The detriment of the approach is that pruning is heavily dependent on the order that pointers were visited. This is especially relevant for hashing a map where map entries are visited in a non-deterministic manner, which would cause the map hash to be non-deterministic (which defeats the point of a hash). This new algorithm uses a stack of all visited pointers, similar to how github.com/google/go-cmp performs cycle detection. When we visit a pointer, we push it onto the stack, and when we leave a pointer, we pop it from the stack. Before visiting a pointer, we first check whether the pointer exists anywhere in the stack. If yes, then we prune the node. The detriment of this approach is that we may hash a node more often than before since we do not prune as aggressively. The set of visited pointers up until any node is only the path of nodes up to that node and not any other pointers that may have been visited elsewhere. This provides us deterministic hashing regardless of visit order. We can now delete hashMapFallback and associated complexity, which only exists because the previous approach was non-deterministic in the presence of cycles. This fixes a failure of the old algorithm where obviously different values are treated as equal because the pruning was too aggresive. See https://github.com/tailscale/tailscale/issues/2443#issuecomment-883653534 The new algorithm is slightly slower since it prunes less aggresively: name old time/op new time/op delta Hash-8 66.1µs ± 1% 68.8µs ± 1% +4.09% (p=0.000 n=19+19) HashMapAcyclic-8 63.0µs ± 1% 62.5µs ± 1% -0.76% (p=0.000 n=18+19) TailcfgNode-8 9.79µs ± 2% 9.88µs ± 1% +0.95% (p=0.000 n=19+17) HashArray-8 643ns ± 1% 653ns ± 1% +1.64% (p=0.000 n=19+19) However, a slower but more correct algorithm seems more favorable than a faster but incorrect algorithm.
