2016-10-06user-util: rework maybe_setgroups() a bitLennart Poettering
Let's drop the caching of the setgroups /proc field for now. While there's a strict regime in place when it changes states, let's better not cache it since we cannot really be sure we follow that regime correctly. More importantly however, this is not in performance sensitive code, and there's no indication the cache is really beneficial, hence let's drop the caching and make things a bit simpler. Also, while we are at it, rework the error handling a bit, and always return negative errno-style error codes, following our usual coding style. This has the benefit that we can sensible hanld read_one_line_file() errors, without having to updat errno explicitly.
2016-10-06tree-wide: drop some misleading compiler warningsLennart Poettering
gcc at some optimization levels thinks thes variables were used without initialization. it's wrong, but let's make the message go anyway.
2016-10-06core: leave PAM stub process around with GIDs updatedLennart Poettering
In the process execution code of PID 1, before 096424d1230e0a0339735c51b43949809e972430 the GID settings where changed before invoking PAM, and the UID settings after. After the change both changes are made after the PAM session hooks are run. When invoking PAM we fork once, and leave a stub process around which will invoke the PAM session end hooks when the session goes away. This code previously was dropping the remaining privs (which were precisely the UID). Fix this code to do this correctly again, by really dropping them else (i.e. the GID as well). While we are at it, also fix error logging of this code. Fixes: #4238
2016-10-06sd-bus: add DNS errors to the errno translation tableLennart Poettering
We generate these, hence we should also add errno translations for them.

2016-10-06sd-device/networkd: unify code to get a socket for issuing netdev ioctls onLennart Poettering
As suggested here: https://github.com/systemd/systemd/pull/4296#issuecomment-251911349 Let's try AF_INET first as socket, but let's fall back to AF_NETLINK, so that we can use a protocol-independent socket here if possible. This has the benefit that our code will still work even if AF_INET/AF_INET6 is made unavailable (for exmple via seccomp), at least on current kernels.

2016-10-04automount: make sure the expire event is restarted after a daemon-reload (#4265)Michael Olbrich
If the corresponding mount unit is deserialized after the automount unit then the expire event is set up in automount_trigger_notify(). However, if the mount unit is deserialized first then the automount unit is still in state AUTOMOUNT_DEAD and automount_trigger_notify() aborts without setting up the expire event. Explicitly call automount_start_expire() during coldplug to make sure that the expire event is set up as necessary. Fixes #4249.

2016-10-04po: updated Swedish translation (#4241)andhe
* po: updated Swedish translation * po: swedish: fix login vs write logs to confusion Since previous commit (updated messages) there's now a mix of different translation meanings for the same thing. While both translations are technically correct I think the meaning of the original messages are probably "to login" rather than "to write log messages to". This commit switches all translations to the "login" meaning.

2016-10-01core: do not try to create /run/systemd/transient in test modeZbigniew Jędrzejewski-Szmek

nss-resolve: return NOTFOUND instead of UNAVAIL for DNSSEC validation failures
2016-10-01nss-resolve: return NOTFOUND instead of UNAVAIL on resolution errorsMartin Pitt
It needs to be possible to tell apart "the nss-resolve module does not exist" (which can happen when running foreign-architecture programs) from "the queried DNS name failed DNSSEC validation" or other errors. So return NOTFOUND for these cases too, and only keep UNAVAIL for the cases where we cannot handle the given address family. This makes it possible to configure a fallback to "dns" without breaking DNSSEC, with "resolve [!UNAVAIL=return] dns". Add this to the manpage. This does not change behaviour if resolved is not running, as that already falls back to the "dns" glibc module. Fixes #4157

2016-09-30resolved: don't query domain-limited DNS servers for other domains (#3621)Martin Pitt
DNS servers which have route-only domains should only be used for the specified domains. Routing queries about other domains there is a privacy violation, prone to fail (as that DNS server was not meant to be used for other domains), and puts unnecessary load onto that server. Introduce a new helper function dns_server_limited_domains() that checks if the DNS server should only be used for some selected domains, i. e. has some route-only domains without "~.". Use that when determining whether to query it in the scope, and when writing resolv.conf. Extend the test_route_only_dns() case to ensure that the DNS server limited to ~company does not appear in resolv.conf. Add test_route_only_dns_all_domains() to ensure that a server that also has ~. does appear in resolv.conf as global name server. These reproduce #3420. Add a new test_resolved_domain_restricted_dns() test case that verifies that domain-limited DNS servers are only being used for those domains. This reproduces #3421. Clarify what a "routing domain" is in the manpage. Fixes #3420 Fixes #3421
2016-09-29pid1: more informative error message for ignored notificationsZbigniew Jędrzejewski-Szmek
It's probably easier to diagnose a bad notification message if the contents are printed. But still, do anything only if debugging is on.
