Denton Gentry	3e7ff5ff98	cmd/tailscaled: enable hybrid netstack mode for FreeBSD. Allows FreeBSD to function as an exit node in the same way that Windows and Tailscaled-on-MacOS do.

julianknodt	b9bd7dbc5d	net/portmapper: log upnp information This logs some basic statistics for UPnP, so that tailscale can better understand what routers are being used and how to connect to them. Signed-off-by: julianknodt <julianknodt@gmail.com>	3 years ago
julianknodt	26b6fe7f02	net/portmapper: add PCP integration test This adds a PCP test to the IGD test server, by hardcoding in a few observed packets from Denton's box. Signed-off-by: julianknodt <julianknodt@gmail.com>	3 years ago
Brad Fitzpatrick	3700cf9ea4	tsweb: also support LabelMaps from expvar.Map, without metrics We want to use tsweb to format Prometheus-style metrics from our temporary golang.org/x/net/http2 fork, but we don't want http2 to depend on the tailscale.com module to use the concrete type tailscale.com/metrics.LabelMap. Instead, let a expvar.Map be used instead of it's annotated sufficiently in its name. Signed-off-by: Brad Fitzpatrick <bradfitz@tailscale.com>	3 years ago

Josh Bleecher Snyder	a4e19f2233	version: remove rsc.io/goversion dependency rsc.io/goversion is really expensive. Running version.ReadExe on tailscaled on darwin allocates 47k objects, almost 11mb. All we want is the module info. For that, all we need to do is scan through the binary looking for the magic start/end strings and then grab the bytes in between them. We can do that easily and quickly with nothing but a 64k buffer. Signed-off-by: Josh Bleecher Snyder <josh@tailscale.com>	3 years ago
Brad Fitzpatrick	bdb93c5942	net/portmapper: actually test something in TestProbeIntegration And use dynamic port numbers in tests, as Linux on GitHub Actions and Windows in general have things running on these ports.

Adrian Dewhurst	8bdf878832	net/dns/resolver: use forwarded dns txid directly Previously, we hashed the question and combined it with the original txid which was useful when concurrent queries were multiplexed on a single local source port. We encountered some situations where the DNS server canonicalizes the question in the response (uppercase converted to lowercase in this case), which resulted in responses that we couldn't match to the original request due to hash mismatches. This includes a new test to cover that situation. Fixes #2597 Signed-off-by: Adrian Dewhurst <adrian@tailscale.com>	3 years ago
David Crawshaw	360223fccb	types/dnstype: introduce new package for Resolver So the type can be used in net/dns without introducing a tailcfg dependency. For #2596 Signed-off-by: David Crawshaw <crawshaw@tailscale.com>	3 years ago
Christine Dodrill	4d19db7c9f	scripts/installer: work on Oracle Linux (#2604 ) Before we didn't detect it properly. Since Oracle Linux is diet centos, we can just make the centos logic detect Oracle linux and everything should be fine. Signed-off-by: Christine Dodrill <xe@tailscale.com>	3 years ago

julianknodt	98d36ee18d	net/portmapper: add hook for use with prev ip PCP handles external IPs by allowing the client to specify them in the packet, which is more explicit than requiring 2 packets from PMP, so allow for future changes to add it in easily.

Brad Fitzpatrick	fdc081c291	net/portmapper: fix UPnP probing, work against all ports Prior to Tailscale 1.12 it detected UPnP on any port. Starting with Tailscale 1.11.x, it stopped detecting UPnP on all ports. Then start plumbing its discovered Location header port number to the code that was assuming port 5000.

Josh Bleecher Snyder	f013960d87	tstime/mono: make json.Unmarshal of a zero time.Time yield a zero Time This was the proximate cause of #2579. #2582 is a deeper fix, but this will remain as a footgun, so may as well fix it too. Signed-off-by: Josh Bleecher Snyder <josh@tailscale.com>	3 years ago

Joe Tsai	9d0c86b6ec	util/deephash: remove unnecessary formatting for structs and slices (#2571 ) The index for every struct field or slice element and the number of fields for the struct is unncessary. The hashing of Go values is unambiguous because every type (except maps) encodes in a parsable manner. So long as we know the type information, we could theoretically decode every value (except for maps). At a high level: * numbers are encoded as fixed-width records according to precision. * strings (and AppendTo output) are encoded with a fixed-width length, followed by the contents of the buffer. * slices are prefixed by a fixed-width length, followed by the encoding of each value. So long as we know the type of each element, we could theoretically decode each element. * arrays are encoded just like slices, but elide the length since it is determined from the Go type. * maps are encoded first with a byte indicating whether it is a cycle. If a cycle, it is followed by a fixed-width index for the pointer, otherwise followed by the SHA-256 hash of its contents. The encoding of maps is not decodeable, but a SHA-256 hash is sufficient to avoid ambiguities. * interfaces are encoded first with a byte indicating whether it is nil. If not nil, it is followed by a fixed-width index for the type, and then the encoding for the underlying value. Having the type be encoded first ensures that the value could theoretically be decoded next. * pointers are encoded first with a byte indicating whether it is 1) nil, 2) a cycle, or 3) newly seen. If a cycle, it is followed by a fixed-width index for the pointer. If newly seen, it is followed by the encoding for the pointed-at value. Removing unnecessary details speeds up hashing: name old time/op new time/op delta Hash-8 76.0µs ± 1% 55.8µs ± 2% -26.62% (p=0.000 n=10+10) HashMapAcyclic-8 61.9µs ± 0% 62.0µs ± 0% ~ (p=0.666 n=9+9) TailcfgNode-8 10.2µs ± 1% 7.5µs ± 1% -26.90% (p=0.000 n=10+9) HashArray-8 1.07µs ± 1% 0.70µs ± 1% -34.67% (p=0.000 n=10+9) Signed-off-by: Joe Tsai <joetsai@digital-static.net>	3 years ago

Joe Tsai	d8fbce7eef	util/deephash: hash uint{8,16,32,64} explicitly (#2502 ) Instead of hashing the humanly formatted forms of a number, hash the native machine bits of the integers themselves.
