Brad Fitzpatrick	036f70b7b4	portlist: refactor, introduce OS-specific types ... Add an osImpl interface that can be stateful and thus more efficient between calls. It will later be implemented by all OSes but for now this change only adds a Linux implementation. Remove Port.inode. It was only used by Linux and moves into its osImpl. Don't reopen /proc/net/* files on each run. Turns out you can just keep then open and seek to the beginning and reread and the contents are fresh. name old time/op new time/op delta GetListIncremental-8 7.29ms ± 2% 6.53ms ± 1% -10.50% (p=0.000 n=9+9) name old alloc/op new alloc/op delta GetListIncremental-8 1.30kB ±13% 0.70kB ± 5% -46.38% (p=0.000 n=9+10) name old allocs/op new allocs/op delta GetListIncremental-8 33.2 ±11% 18.0 ± 0% -45.82% (p=0.000 n=9+10) Updates #5958 Change-Id: I4be83463cbd23c2e2fa5d0bdf38560004f53401b Signed-off-by: Brad Fitzpatrick <bradfitz@tailscale.com>	2 years ago
Peter Cai	4597ec1037	net/dnscache: Handle 4-in-6 addresses in DNS responses ... On Android, the system resolver can return IPv4 addresses as IPv6-mapped addresses (i.e. `::ffff:a.b.c.d`). After the switch to `net/netip` (19008a3), this case is no longer handled and a response like this will be seen as failure to resolve any IPv4 addresses. Handle this case by simply calling `Unmap()` on the returned IPs. Fixes #5698. Signed-off-by: Peter Cai <peter@typeblog.net>	2 years ago

Anton Tolchanov	bd47e28638	prober: optionally spread probes over time ... By default all probes with the same probe interval that have been added together will run on a synchronized schedule, which results in spiky resource usage and potential throttling by third-party systems (for example, OCSP servers used by the TLS probes). To address this, prober can now run in "spread" mode that will introduce a random delay before the first run of each probe. Signed-off-by: Anton Tolchanov <anton@tailscale.com>	2 years ago

Brad Fitzpatrick	deac82231c	wgengine/magicsock: add start of alternate send path ... During development of silent disco (#540), an alternate send policy for magicsock that doesn't wake up the radio frequently with heartbeats, we want the old & new policies to coexist, like we did previously pre- and post-disco. We started to do that earlier in 5c42990c2f but only set up the env+control knob plumbing to set a bool about which path should be used. This starts to add a way for the silent disco code to update the send path from a separate goroutine. (Part of the effort is going to de-state-machinify the event based soup that is the current disco code and make it more Go synchronous style.) So far this does nothing. (It does add an atomic load on each send but that should be noise in the grand scheme of things, and a even more rare atomic store of nil on node config changes.) Baby steps.

The Lufthansa in-flight wifi generates a synthetic 204 response to the DERP server's /generate_204 endpoint. This PR adds a basic challenge/response to the endpoint; something sufficiently complicated that it's unlikely to be implemented by a captive portal.
