Josh Bleecher Snyder	4c8b5fdec4	control/controlclient: do not periodically print full netmap The netmaps can get really large. Printing, processing, and uploading them is expensive. Only print the header on an ongoing basis. Signed-off-by: Josh Bleecher Snyder <josh@tailscale.com>	3 years ago
Josh Bleecher Snyder	a666b546fb	ipn/ipnlocal: log number of packet filters rather than entire filter The number of packet filters can grow very large, so this log entry can be very large. We can get the packet filter server-side, so reduce verbosity here to just the number of filters present. Signed-off-by: Josh Bleecher Snyder <josh@tailscale.com>	3 years ago
Josh Bleecher Snyder	0c038b477f	logtail: add a re-usable buffer for uploads This avoids a per-upload alloc (which in practice often means per-log-line), up to 4k. Signed-off-by: Josh Bleecher Snyder <josh@tailscale.com>	3 years ago
Josh Bleecher Snyder	278e7de9c9	logtail: always send a json array The code goes to some effort to send a single JSON object when there's only a single line and a JSON array when there are multiple lines. It makes the code more complex and more expensive; when we add a second line, we have to use a second buffer to duplicate the first one after adding a leading square brackets. The savings come to two bytes. Instead, always send an array. Signed-off-by: Josh Bleecher Snyder <josh@tailscale.com>	3 years ago
Josh Bleecher Snyder	93284209bc	logtail/filch: preallocate a scanner buffer Scanning log lines is a frequent source of allocations. Pre-allocate a re-usable buffer. This still doesn't help when there are giant log lines. Those will still be problematic from an iOS memory perspective. For more on that, see https://github.com/tailscale/corp/issues/2423. (For those who cannot follow that link, it is a discussion of particular problematic types of log lines for particular categories of customers. The "categories of customers" part is the reason that it is a private issue.) There is also a latent bug here. If we ever encounter a log line longer than bufio.MaxScanTokenSize, then bufio.Scan will return an error, and we'll truncate the file and discard the rest of the log. That's not good, but bufio.MaxScanTokenSize is really big, so it probably doesn't matter much in practice now. Unfortunately, it does prevent us from easily capping the potential memory usage here, on pain of losing log entries. Signed-off-by: Josh Bleecher Snyder <josh@tailscale.com>	3 years ago
Matt Layher	8ab44b339e	net/tstun: use unix.Ifreq type for Linux TAP interface configuration Signed-off-by: Matt Layher <mdlayher@gmail.com>	3 years ago
Josh Bleecher Snyder	6da6d47a83	all: simplify build tags involving iOS Prior to Go 1.16, iOS used GOOS=darwin, so we had to distinguish macOS from iOS during GOARCH. We now require Go 1.16 in our go.mod, so we can simplify. Signed-off-by: Josh Bleecher Snyder <josh@tailscale.com>	3 years ago
Josh Bleecher Snyder	a24cee0d67	all: simplify ts_macext build tags Now that we have the easier-to-parse go:build build tags, it is straightforward to simplify them. Yay. Signed-off-by: Josh Bleecher Snyder <josh@tailscale.com>	3 years ago

Brad Fitzpatrick	833200da6f	net/tstun: don't exec uname -r on Linux in TUN failure diagnostics Fixes https://twitter.com/zekjur/status/1425557520513486848 Signed-off-by: Brad Fitzpatrick <bradfitz@tailscale.com>	3 years ago
Brad Fitzpatrick	e804ab29fd	net/tstun: move TUN failure diagnostics to OS-specific files Mostly so the Linux one can use Linux-specific stuff in package syscall and not use os/exec for uname for portability. But also it helps deps a tiny bit on iOS. Signed-off-by: Brad Fitzpatrick <bradfitz@tailscale.com>	3 years ago
Brad Fitzpatrick	b2eea1ee00	cmd/tailscale/cli: make cert fetch registration automatic, show valid domains Updates #1235 Signed-off-by: Brad Fitzpatrick <bradfitz@tailscale.com>	3 years ago
Brad Fitzpatrick	39610aeb09	wgengine/magicsock: move debug knobs to their own file, compile out on iOS No need for these knobs on iOS where you can set the environment variables anyway. Signed-off-by: Brad Fitzpatrick <bradfitz@tailscale.com>	3 years ago
Denton Gentry	98d557dd24	Dockerfile: use alpine:3.14 golang:1.16-alpine has updated to Alpine 3.14, update the system image to match. Reported by @kubeworm https://twitter.com/kubeworm/status/1426751941519020033 Signed-off-by: Denton Gentry <dgentry@tailscale.com>	3 years ago
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. RELNOTE=FreeBSD can now function as an exit node. Fixes https://github.com/tailscale/tailscale/issues/2498 Signed-off-by: Denton Gentry <dgentry@tailscale.com>	3 years ago

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.
