Adrian Dewhurst	bcaae3e074	net/dns/resolver: clamp EDNS size This change (subject to some limitations) looks for the EDNS OPT record in queries and responses, clamping the size field to fit within our DNS receive buffer. If the size field is smaller than the DNS receive buffer then it is left unchanged. I think we will eventually need to transition to fully processing the DNS queries to handle all situations, but this should cover the most common case. Mostly fixes #2066 Signed-off-by: Adrian Dewhurst <adrian@tailscale.com>	3 years ago

julianknodt	148602a89a	derp,cmd/derper: allow server to verify clients This adds a flag to the DERP server which specifies to verify clients through a local tailscaled. It is opt-in, so should not affect existing clients, and is mainly intended for users who want to run their own DERP servers. It assumes there is a local tailscaled running and will attempt to hit it for peer status information. Updates #1264 Signed-off-by: julianknodt <julianknodt@gmail.com>	3 years ago
Brad Fitzpatrick	c45bfd4180	wgengine: make dnsIPsOverTailscale also consider DefaultResolvers Found during a failed experiment debugging something on Android. Signed-off-by: Brad Fitzpatrick <bradfitz@tailscale.com>	3 years ago
Brad Fitzpatrick	7b8ed1fc09	net/netns: add Android implementation, allowing registration of JNI hook Updates #2102 Updates #1809 Signed-off-by: Brad Fitzpatrick <bradfitz@tailscale.com>	3 years ago
Brad Fitzpatrick	b92e2ebd24	wgengine/netstack: add Impl.DialContextUDP Unused so far, but eventually we'll want this for SOCKS5 UDP binds (we currently only do TCP with SOCKS5), and also for #2102 for forwarding MagicDNS upstream to Tailscale IPs over netstack. Updates #2102 Signed-off-by: Brad Fitzpatrick <bradfitz@tailscale.com>	3 years ago

David Anderson	084d48d22d	net/dns: always proxy through quad-100 on windows 8.1. Windows 8.1 incorrectly handles search paths on an interface with no associated resolver, so we have to provide a full primary DNS config rather than use Windows 8.1's nascent-but-present NRPT functionality. Fixes #2237. Signed-off-by: David Anderson <danderson@tailscale.com>	3 years ago
Brad Fitzpatrick	45e64f2e1a	net/dns{,/resolver}: refactor DNS forwarder, send out of right link on macOS/iOS Fixes #2224 Fixes tailscale/corp#2045 Signed-off-by: Brad Fitzpatrick <bradfitz@tailscale.com>	3 years ago
julianknodt	597fa3d3c3	tailcfg/derpmap: add flag to omit ts's derps This adds a flag to derp maps which specifies that default Tailscale DERP servers should not be used. If true and there are entries in this map, it indicates that the entries in this map should take precedent and not hit any of tailscale's DERP servers. This change is backwards compatible, as the default behavior should be false. Updates #1264 Signed-off-by: julianknodt <julianknodt@gmail.com>	3 years ago

julianknodt	0f18801716	cmd/cloner: support maps with clone ptrs In order to clone DERPMaps, it was necessary to extend the cloner so that it supports nested pointers inside of maps which are also cloneable. This also adds cloning for DERPRegions and DERPNodes because they are on DERPMap's maps. Signed-off-by: julianknodt <julianknodt@gmail.com>	3 years ago

Denton Gentry	ad288baaea	net/interfaces: use IPv4 link local if nothing better The only connectivity an AWS Lambda container has is an IPv4 link-local 169.254.x.x address using NAT: 12: vtarget_1@if11: <BROADCAST,MULTICAST,UP,LOWER_UP> mtu 1500 qdisc noqueue state UP group default qlen 1000 link/ether 7e:1c:3f:00:00:00 brd ff:ff:ff:ff:ff:ff link-netnsid 1 inet 169.254.79.1/32 scope global vtarget_1 valid_lft forever preferred_lft forever If there are no other IPv4/v6 addresses available, and we are running in AWS Lambda, allow IPv4 169.254.x.x addresses to be used. ---- Similarly, a Google Cloud Run container's only connectivity is a Unique Local Address fddf:3978:feb1:d745::c001/128. If there are no other addresses available then allow IPv6 Unique Local Addresses to be used. We actually did this in an earlier release, but now refactor it to work the same way as the IPv4 link-local support is being done. Signed-off-by: Denton Gentry <dgentry@tailscale.com>	3 years ago
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	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
