2021-01-14all: convert from []wgcfg.Endpoint to stringJosh Bleecher Snyder1-4/+7
This eliminates a dependency on wgcfg.Endpoint, as part of the effort to eliminate our wireguard-go fork. Signed-off-by: Josh Bleecher Snyder <josh@tailscale.com>

2021-01-12control/controlclient: treat node sharer as owner for display purposesBrad Fitzpatrick1-0/+14
This make clients (macOS, Windows, tailscale status) show the node sharer's profile rather than the node owner (which may be anonymized). Updates #992

2021-01-10cmd/tailscale: change formatting of "tailscale status"Brad Fitzpatrick1-1/+25
* show DNS name over hostname, removing domain's common MagicDNS suffix. only show hostname if there's no DNS name. but still show shared devices' MagicDNS FQDN. * remove nerdy low-level details by default: endpoints, DERP relay, public key. They're available in JSON mode still for those who need them. * only show endpoint or DERP relay when it's active with the goal of making debugging easier. (so it's easier for users to understand what's happening) The asterisks are gone. * remove Tx/Rx numbers by default for idle peers; only show them when there's traffic. * include peers' owner login names * add CLI option to not show peers (matching --self=true, --peers= also defaults to true) * sort by DNS/host name, not public key * reorder columns

2021-01-08control/controlclient: use lite map request handler to avoid aborting streamsBrad Fitzpatrick2-13/+83
Previously, any change to endpoints or hostinfo (or hostinfo's netinfo) would result in the long-running map request HTTP stream being torn down and restarted, losing all compression context along with it. This change makes us instead send a lite map request (OmitPeers: true, Stream: false) that doesn't subscribe to anything, and then the coordination server knows to not close other streams for that node when it recives a lite request. Fixes tailscale/corp#797 Signed-off-by: Brad Fitzpatrick <bradfitz@tailscale.com>
2021-01-05ipn: delete domainsForProxying, require explicit DNS search domains (mapver ↵Brad Fitzpatrick1-1/+1
9) (#1078) Previously the client had heuristics to calculate which DNS search domains to set, based on the peers' names. Unfortunately that prevented us from doing some things we wanted to do server-side related to node sharing. So, bump MapRequest.Version to 9 to signal that the client only uses the explicitly configured DNS search domains and doesn't augment it with its own list.

2020-12-30wgkey: new packageJosh Bleecher Snyder4-31/+32
This is a replacement for the key-related parts of the wireguard-go wgcfg package. This is almost a straight copy/paste from the wgcfg package. I have slightly changed some of the exported functions and types to avoid stutter, added and tweaked some comments, and removed some now-unused code. To avoid having wireguard-go depend on this new package, wgcfg will keep its key types. We translate into and out of those types at the last minute. These few remaining uses will be eliminated alongside the rest of the wgcfg package. Signed-off-by: Josh Bleecher Snyder <josh@tailscale.com>

The fallthrough happened to work in controlclient already due to the /etc/os-release PRETTY_NAME default, but make it explicit so it doesn't look like an accident. Also add it to version/distro, even though nothing needs it yet.

Addresses #964 Still to be done: - Figure out the correct logging lines in util/systemd - Figure out if we need to slip the systemd.Status function anywhere else - Log util/systemd errors? (most of the errors are of the "you cannot do anything about this, but it might be a bad idea to crash the program if it errors" kind) Assistance in getting this over the finish line would help a lot.

After mapver 5's incremental netmap updates & user profiles, much of the remaining bandwidth for streamed MapResponses were redundant, unchanged PacketFilters. So make MapRequest.Version 6 mean that nil means unchanged from the previous value.

When building with redo, also include the git commit hash from the proprietary repo, so that we have a precise commit that identifies all build info (including Go toolchain version). Add a top-level build script demonstrating to downstream distros how to burn the right information into builds. Adjust `tailscale version` to print commit hashes when available. Fixes #841.

2020-10-14control/controlclient: also include our own profile (for when no self-owned ↵Brad Fitzpatrick1-4/+7
peers) Fix from regression in previous commit (0e3048d8e01921758655dea212ecf010346d9300) that was caught by e2e tests. In that previous commit, the user's own profile was omitted from the NetworkMap in the case where the user only had one node.
2020-10-14control/controlclient: support delta userprofiles from controlBrad Fitzpatrick1-2/+13
I was going to make support for this advertised from the client, but turns out only "tailscale status" even uses the UserProfiles field and fails gracefully (omits that field) if a user profile for a user is missing, so I think we can just reuse the DeltaPeers field from the client to ask the control server to also delta encode the user profiles. For the few users running 1.1.x (unstable) versions between DeltaPeers support (1.1.82) and this (~1.1.541), they'll just sometimes have missing names in "tailscale status --json" or "tailscale status --web" (the only places the UserProfile is used).
2020-10-14control/controlclient: adjust some logging point namesBrad Fitzpatrick1-5/+5
The previous code read too explicitly like log.Printf("I am here1"), log.Printf("I am here2"). It still is with this change, but prettier, and less subject to code rearranging order.
2020-10-14control/controlclient: set MapRequest.ReadOnly on initial empty endpoint requestBrad Fitzpatrick1-8/+33
On startup, clients do a MapRequest with empty endpoints while they learn the DERP map to discover the STUN servers they then query to learn their endpoints. Set MapRequest.ReadOnly on those initial queries to not broadcast the empty endpoints out to peers. The read results will come a half second later (or less). Updates tailscale/corp#557
2020-10-08controlclient: print http errors if result code != 200.apenwarr/faketunAvery Pennarun1-1/+7
Turns out for the particular error I was chasing, it actually returns 200 and zero data. But this code mirrors the same check in the map poll, and is the right thing to do in the name of future debugging. Signed-off-by: Avery Pennarun <apenwarr@tailscale.com>

2020-09-17tailcfg: add MapRequest.ReadOnly and OmitPeers; remove DebugForceDiscoBrad Fitzpatrick1-25/+19
DebugForceDisco was a development & safety knob during the the transition to discovery. It's no longer needed. Add MapRequest.ReadOnly to prevent clients needing to do two peer-spamming MapRequest at start-up. This only adds the field, not the use of the field. (The control server needs to support it first.)
