Brad Fitzpatrick	2a67beaacf	net/interfaces: bound Linux /proc/net/route parsing tailscaled was using 100% CPU on a machine with ~1M lines, 100MB+ of /proc/net/route data. Two problems: in likelyHomeRouterIPLinux, we didn't stop reading the file once we found the default route (which is on the first non-header line when present). Which meant it was finding the answer and then parsing 100MB over 1M lines unnecessarily. Second was that if the default route isn't present, it'd read to the end of the file looking for it. If it's not in the first 1,000 lines, it ain't coming, or at least isn't worth having. (it's only used for discovering a potential UPnP/PMP/PCP server, which is very unlikely to be present in the environment of a machine with a ton of routes) Change-Id: I2c4a291ab7f26aedc13885d79237b8f05c2fd8e4 Signed-off-by: Brad Fitzpatrick <bradfitz@tailscale.com>	3 years ago

Aaron Klotz	d7962e3bcf	ipn/ipnserver, util/winutil: update workaround for os/user.LookupId failures on Windows to reject SIDs from deleted/invalid security principals. Our current workaround made the user check too lax, thus allowing deleted users. This patch adds a helper function to winutil that checks that the uid's SID represents a valid Windows security principal. Now if `lookupUserFromID` determines that the SID is invalid, we simply propagate the error.

Brad Fitzpatrick	bd90781b34	ipn/ipnlocal, wgengine/netstack: use netstack for peerapi server We're finding a bunch of host operating systems/firewalls interact poorly with peerapi. We either get ICMP errors from the host or users need to run commands to allow the peerapi port: https://github.com/tailscale/tailscale/issues/3842#issuecomment-1025133727 ... even though the peerapi should be an internal implementation detail. Rather than fight the host OS & firewalls, this change handles the server side of peerapi entirely in netstack (except on iOS), so it never makes its way to the host OS where it might be messed with. Two main downsides are: 1) netstack isn't as fast, but we don't really need speed for peerapi. And actually, with fewer trips to/from the kernel, we might actually make up for some of the netstack performance loss by staying in userspace. 2) tcpdump / Wireshark etc packet captures will no longer see the peerapi traffic. Oh well. Crawshaw's been wanting to add packet capture server support to tailscaled, so we'll probably do that sooner now. A future change might also then use peerapi for the client-side (except on iOS).

Brad Fitzpatrick	1af26222b6	go.mod: bump netstack, switch to upstream netstack Now that Go 1.17 has module graph pruning (https://go.dev/doc/go1.17#go-command), we should be able to use upstream netstack without breaking our private repo's build that then depends on the tailscale.com Go module. This is that experiment. Updates #1518 (the original bug to break out netstack to own module) Updates #2642 (this updates netstack, but doesn't remove workaround) Change-Id: I27a252c74a517053462e5250db09f379de8ac8ff Signed-off-by: Brad Fitzpatrick <bradfitz@tailscale.com>	3 years ago

Aaron Bieber	411c6c316c	net/dns/resolvd: store nameservers Currently only search domains are stored. This was an oversight (under?) on my part. As things are now, when MagicDNS is on and "Override local DNS" is off, the dns forwarder has to timeout before names resolve. This introduces a pretty annoying lang that makes everything feel extremely slow. You will also see an error: "upstream nameservers not set". I tested with "Override local DNS" on and off. In both situations things seem to function as expected (and quickly). Signed-off-by: Aaron Bieber <aaron@bolddaemon.com>	3 years ago

David Anderson	d5a7eabcd0	control/controlbase: enable asynchronous client handshaking. With this change, the client can obtain the initial handshake message separately from the rest of the handshake, for embedding into another protocol. This enables things like RTT reduction by stuffing the handshake initiation message into an HTTP header. Similarly, the server API optionally accepts a pre-read Noise initiation message, in addition to reading the message directly off a net.Conn.

David Anderson	463b3e8f62	net/dnscache: use tls.Conn.HandshakeContext.

David Anderson	a9da6b73a8	net/dnscache: don't cancel the TLS context before writing to the result channel. Cancelling the context makes the timeout goroutine race with the write that reports a successful TLS handshake, so you can end up with a successful TLS handshake that mysteriously reports that it timed out after ~0s in flight. The context is always canceled and cleaned up as the function exits, which happens mere microseconds later, so just let function exit clean up and thereby avoid races.
