julianknodt	3687e5352b	derp: fix traffic handler peer addresses Before it was using the local address and port, so fix that. The fields in the response from `ss` are: State, Recv-Q, Send-Q, Local Address:Port, Peer Address:Port, Process Signed-off-by: julianknodt <julianknodt@gmail.com>	3 years ago

julianknodt	3728634af9	derp: add debug traffic handler This adds a handler on the DERP server for logging bytes send and received by clients of the server, by holding open a connection and recording if there is a difference between the number of bytes sent and received. It sends a JSON marshalled object if there is an increase in the number of bytes. Signed-off-by: julianknodt <julianknodt@gmail.com>	3 years ago

Christine Dodrill	e0f0d10672	tstest/integration/vms: log to t.Logf directly (#2147 ) Previously we used t.Logf indirectly via package log. This worked, but it was not ideal for our needs. It could cause the streams of output to get crossed. This change uses a logger.FuncWriter every place log.Output was previously used, which will more correctly write log information to the right test output stream.

David Anderson	9337826011	net/dns: fix inverted test for NetworkManager version. Signed-off-by: David Anderson <danderson@tailscale.com>	3 years ago
David Anderson	320cc8fa21	net/dns: verify that systemd-resolved is actually in charge. It's possible to install a configuration that passes our current checks for systemd-resolved, without actually pointing to systemd-resolved. In that case, we end up programming DNS in resolved, but that config never applies to any name resolution requests on the system. This is quite a far-out edge case, but there's a simple additional check we can do: if the header comment names systemd-resolved, there should be a single nameserver in resolv.conf pointing to 127.0.0.53. If not, the configuration should be treated as an unmanaged resolv.conf. Fixes #2136. Signed-off-by: David Anderson <danderson@tailscale.com>	3 years ago
David Anderson	e7164425b3	net/dns: don't use NetworkManager for DNS on very old NetworkManagers. Fixes #1945. Signed-off-by: David Anderson <danderson@tailscale.com>	3 years ago
David Anderson	ac07ff43bf	cmd/tailscaled: start after NetworkManager and systemd-resolved. The dependency is a "soft" ordering dependency only, meaning that tailscaled will start after those services if those services were going to be run anyway, but doesn't force either of them to run. That's why it's safe to specify this dependency unconditionally, even for systems that don't run those services. Updates #2127. Signed-off-by: David Anderson <danderson@tailscale.com>	3 years ago

Julian Knodt	525eb5ce41	Merge pull request #2092 from tailscale/queue_latency derp: add pkt queue latency timer	4 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>	4 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.

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.

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>	4 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.
