2017-02-17resolved: extend various timeoutsLennart Poettering
Let's increase a number of timeouts as they apparently are too short for some real-world lookups. See: https://github.com/systemd/systemd/issues/4003#issuecomment-279842616 In particular we change the following timeouts: 1) The first UDP retry we increase 500ms → 750ms. This is a good idea, since some servers need relatively long responses for trivial lookups, and giving up our first attempt also has the effect of trying a different server for the next attempt which has the side effect that we'll run two down-grade iterations in parallel, on both servers. Hence, let's give servers a bit more time in the first iteration. 2) Permit 24 retries instead of just 16 per transactions. If we end up downgrading all the way down to UDP for a lookup we already need 5 iterations for that. If we want permit a couple of lost packages for each (let's say 4), then we already need 20 iterations. 3) Increase the overall query timeout on the service side to 60s (from 45s), simply because very long and slow DNSSEC + CNAME chains (such as us.ynuf.alipay.com) hit this boundary too easily. The client side timeout for the bus method call is increased to 90s, in order to have room for the dbus reply to go through

2017-02-09tree-wide: make bus_map_all_properties return a proper sd_bus_errorLennart Poettering
And then show it, to make things a bit friendlier to the user if we fail acquiring some props. In fact, this fixes a number of actual bugs, where we used an error structure for output that we actually never got an error in.

1. Listed in TODO. 2. Tree wide replace safe_atou16 with parse_ip_port incase it's used for ports.

2016-07-17systemd-resolve: use plural "DNS Servers"Zbigniew Jędrzejewski-Szmek
Usually multiple DNS servers are configured, and it looks strange to have singular in the heading.
2016-06-21resolve: add "systemd-resolve --status" commandLennart Poettering
The new command shows the per-link and global DNS configuration currently in effect. This is useful to quickly see the DNS settings resolved acquired from networkd and that was pushed into it via the bus APIs.

We can reuse some code here, so let's do it.

And expose it in "resolve-tool --flush-caches".

2016-03-27build-sys: fix build with libgrcypt disabledZbigniew Jędrzejewski-Szmek
- Move gcrypt.h include inside grcrypt-util.h. - Allow gcrypt-util.[ch] to be compiled even without gcrypt. This allows the logic in files using gcrypt to be simplified. - Fix compilation of systemd-resolve without gcrypt. systemd-resolved already supported that. Fixes #2711.

The output didn't specify if the default for --cname/--search/--legend and other options was yes or no. Change the description to be explicit about that. Also make the --help output and man page closer.

authenticated Doing DNS retrieval on non-authenticated crypt keys is useless, hence warn loudly about it.

This should be handled fine now by .dir-locals.el, so need to carry that stuff in every file.

Now that we count both negative and positive validation results, we shouldn't claim we just counted RRsets.

2016-01-25resolve: rename "systemd-resolve-host" tool to simply "systemd-resolve"Lennart Poettering
The tool resolves way more than just hosts, hence give it a more generic name. This should be safe, as the tool is currently undocumented. Before we add documentation for it, let's get the name right. This also moves the C source into src/resolve/ (from src/resolve-host/), since the old name is a misnomer now. Also, since it links directly to many of the C files of resolved it really belongs into resolved's directory anyway.
