Julian Knodt	525eb5ce41	Merge pull request #2092 from tailscale/queue_latency derp: add pkt queue latency timer	3 years ago
julianknodt	fe54721e31	derp: add pkt queue latency timer It would be useful to know the time that packets spend inside of a queue before they are sent off, as that can be indicative of the load the server is handling (and there was also an existing TODO). This adds a simple exponential moving average metric to track the average packet queue duration. Changes during review: Add CAS loop for recording queue timing w/ expvar.Func, rm snake_case, annotate in milliseconds, convert Signed-off-by: julianknodt <julianknodt@gmail.com>	3 years ago

Christine Dodrill	8b2b899989	tstest/integration: test Alpine Linux (#2098 ) Alpine Linux[1] is a minimal Linux distribution built around musl libc. It boots very quickly, requires very little ram and is as close as you can get to an ideal citizen for testing Tailscale on musl. Alpine has a Tailscale package already[2], but this patch also makes it easier for us to provide an Alpine Linux package off of pkgs in the future. Alpine only offers Tailscale on the rolling-release edge branch.

Brad Fitzpatrick	0affcd4e12	tstest/integration: add some debugging for TestAddPingRequest flakes This fails pretty reliably with a lot of output now showing what's happening: TS_DEBUG_MAP=1 go test --failfast -v -run=Ping -race -count=20 ./tstest/integration --verbose-tailscaled I haven't dug into the details yet, though.

Fletcher Nichol	a49df5cfda	wgenine/router: fix OpenBSD route creation The route creation for the `tun` device was augmented in #1469 but didn't account for adding IPv4 vs. IPv6 routes. There are 2 primary changes as a result: * Ensure that either `-inet` or `-inet6` was used in the [`route(8)`](https://man.openbsd.org/route) command * Use either the `localAddr4` or `localAddr6` for the gateway argument depending which destination network is being added The basis for the approach is based on the implementation from `router_userspace_bsd.go`, including the `inet()` helper function.

Dave Anderson	144c68b80b	net/dns: avoid using NetworkManager as much as possible. (#1945 ) Addresses #1699 as best as possible. Signed-off-by: David Anderson <danderson@tailscale.com>	3 years ago
Maisem Ali	f944614c5c	cmd/tailscale/web: add support for QNAP Signed-off-by: Maisem Ali <maisem@tailscale.com>	3 years ago
Adrian Dewhurst	8b11937eaf	net/dns/resolver: permit larger max responses, signal truncation This raises the maximum DNS response message size from 512 to 4095. This should be large enough for almost all situations that do not need TCP. We still do not recognize EDNS, so we will still forward requests that claim support for a larger response size than 4095 (that will be solved later). For now, when a response comes back that is too large to fit in our receive buffer, we now set the truncation flag in the DNS header, which is an improvement from before but will prompt attempts to use TCP which isn't supported yet. On Windows, WSARecvFrom into a buffer that's too small returns an error in addition to the data. On other OSes, the extra data is silently discarded. In this case, we prefer the latter so need to catch the error on Windows. Partially addresses #1123 Signed-off-by: Adrian Dewhurst <adrian@tailscale.com>	3 years ago

Christine Dodrill	b402e76185	.github/workflows: add integration test with a custom runner (#2044 ) This runner is in my homelab while we muse about a better, more permanent home for these tests. Updates #1988 Signed-off-by: Christine Dodrill <xe@tailscale.com>	3 years ago
Christine Dodrill	622dc7b093	tstest/integration/vms: download images from s3 (#2035 ) This makes integration tests pull pristine VM images from Amazon S3 if they don't exist on disk. If the S3 fetch fails, it will fall back to grabbing the image from the public internet. The VM images on the public internet are known to be updated without warning and thusly change their SHA256 checksum. This is not ideal for a test that we want to be able to fire and forget, then run reliably for a very long time. This requires an AWS profile to be configured at the default path. The S3 bucket is rigged so that the requester pays. The VM images are currently about 6.9 gigabytes. Please keep this in mind when running these tests on your machine. Documentation was added to the integration test folder to aid others in running these tests on their machine. Some wording in the logs of the tests was altered.

Christine Dodrill	3f1405fa2a	tstest/integration/vms: bump images, fix caching bug (#2052 ) Before this redownloaded the image every time. Now it only redownloads it when it needs to. Signed-off-by: Christine Dodrill <xe@tailscale.com>	3 years ago

David Anderson	dfb1385fcc	build_dist.sh: add a command to output the shell vars. Some downstream distros eval'd version/version.sh to get at the shell variables within their own build process.

Christine Dodrill	adaecd83c8	tstest/integration/vms: add DownloadImages test to download images (#2039 ) The image downloads can take a significant amount of time for the tests. This creates a new test that will download every distro image into the local cache in parallel, optionally matching the distribution regex.

Christine Dodrill	607b7ab692	tstest/integration/vms: aggressively re-verify shasums (#2050 ) I've run into a couple issues where the tests time out while a VM image is being downloaded, making the cache poisoned for the next run. This moves the hash checking into its own function and calls it much sooner in the testing chain. If the hash check fails, the OS is redownloaded.

Christine Dodrill	6ce77b8eca	tstest/integration/vms: log qemu output (#2047 ) Most of the time qemu will output nothing when it is running. This is expected behavior. However when qemu is unable to start due to some problem, it prints that to either stdout or stderr. Previously this output wasn't being captured. This patch captures that output to aid in debugging qemu issues. Updates #1988 Signed-off-by: Christine Dodrill <xe@tailscale.com>	3 years ago

Brad Fitzpatrick	ecfb2639cc	ipn/ipnlocal: avoid initPeerAPIListener crash on certain concurrent actions We were crashing on in initPeerAPIListener when called from authReconfig when b.netMap is nil. But authReconfig already returns before the call to initPeerAPIListener when b.netMap is nil, but it releases the b.mu mutex before calling initPeerAPIListener which reacquires it and assumes it's still nil. The only thing that can be setting it to nil is setNetMapLocked, which is called by ResetForClientDisconnect, Logout/logout, or Start, all of which can happen during an authReconfig. So be more defensive. Fixes #1996 Signed-off-by: Brad Fitzpatrick <bradfitz@tailscale.com>	3 years ago
Brad Fitzpatrick	713c5c9ab1	net/{interfaces,netns}: change which build tag means mac/ios Network/System Extension We used to use "redo" for that, but it was pretty vague. Also, fix the build tags broken in interfaces_default_route_test.go from `a9745a0b68`, moving those Linux-specific tests to interfaces_linux_test.go.

Christine Dodrill	0a655309c6	tstest/integration/vms: only build binaries once (#2042 ) Previously this built the binaries for every distro. This is a bit overkill given we are using static binaries. This patch makes us only build once. There was also a weird issue with how processes were being managed. Previously we just killed qemu with Process.Kill(), however that was leaving behind zombies. This has been mended to not only kill qemu but also waitpid() the process so it doesn't become a zombie. Updates #1988 Signed-off-by: Christine Dodrill <xe@tailscale.com>	3 years ago
Christine Dodrill	a282819026	tstest/integration/vms: fix OpenSUSE Leap 15.1 (#2038 ) The OpenSUSE 15.1 image we are using (and conseqentially the only one that is really available easily given it is EOL) has cloud-init hardcoded to use the OpenStack metadata thingy. Other OpenSUSE Leap images function fine with the NoCloud backend, but this one seems to just not work with it. No bother, we can just pretend to be OpenStack. Thanks to Okami for giving me an example OpenStack configuration seed image. Updates #1988 Signed-off-by: Christine Dodrill <xe@tailscale.com>	3 years ago
Christine Dodrill	4da5e79c39	tstest/integration/vms: test on Arch Linux (#2040 ) Arch is a bit of a weirder distro, however as a side effect it is much more of a systemd purist experience.
