2015-08-21resolved: add extra check for family when doing LLMNR TCP connectionsLennart Poettering
It shouldn't happen that we try to resolve IPv4 addresses via LLMNR on IPv6 and vice versa, but let's explicitly verify that we don't turn an IPv4 LLMNR lookup into an IPv6 TCP connection.

resolved: synthesize more RRs locally and other fixes
2015-08-21resolved: rework synthesizing logicLennart Poettering
With this change we'll now also generate synthesized RRs for the local LLMNR hostname (first label of system hostname), the local mDNS hostname (first label of system hostname suffixed with .local), the "gateway" hostname and all the reverse PTRs. This hence takes over part of what nss-myhostname already implemented. Local hostnames resolve to the set of local IP addresses. Since the addresses are possibly on different interfaces it is necessary to change the internal DnsAnswer object to track per-RR interface indexes, and to change the bus API to always return the interface per-address rather than per-reply. This change also patches the existing clients for resolved accordingly (nss-resolve + systemd-resolve-host). This also changes the routing logic for queries slightly: we now ensure that the local hostname is never resolved via LLMNR, thus making it trustable on the local system.
2015-08-21resolved: make DnsQuestion logic handle NULL arrays as empty arraysLennart Poettering
Following our usual logic of treating NULL arrays as empty arrays (for example, see strv.c) do the same for questions too.

This is specifically useful for appending the mDNS ".local" suffix to a single-label hostname in the most correct way. (used in later commit)

2015-08-21hostname-util: introduce new is_gateway_hostname() callLennart Poettering
This moves is_gateway() from nss-myhostname into the basic APIs, and makes it more like is_localhost(). Also, we rename it to is_gateway_hostname() to make it more expressive. Sharing this function in src/basic/ allows us to reuse the function for routing name requests in resolved (in a later commit).

Add a helper function containing a modified version of dns_packet_read_name() that does not use DnsPacket to extract a string array of domain names from the provided option data. The domain names are stored uncompressed as defined in Section 8. of RFC 3315.

As the lease structure contains interesting information, save it also for the Information Reply.
2015-08-21sd-dhcp6-client: Fix unreferencing DHCPv6 lease on client resetPatrik Flykt
When the DHCPv6 client is started by the library user or stopped for any reason, unref the DHCPv6 lease when resetting the DHCPv6 client data structure. This makes the DHCPv6 client always start from a clean state and not keep unnecessary an lease structure around when stopped. If this is not done, a previously existing lease information can be interpreted to be from another server when restarting DHCPv6.

timedatectl: assert timezone is not null in setenv() call.
2015-08-19timedatectl: assert timezone is not null in setenv() call.Dimitri John Ledkov
setenv is declared as: extern int setenv (const char *__name, const char *__value, int __replace) __THROW __nonnull ((2)); And i->timezone can be NULL, if for example /etc/localtime is missing. Previously that worked, but now result in a libc dumping core, as seen with gcc 2.22, due to: https://sourceware.org/ml/glibc-cvs/2015-q2/msg00075.html

2015-08-18logind: get a fresh file descriptor to clean up a VTOwen W. Taylor
When the controlling process exits, any existing file descriptors for that FD will be marked as hung-up and ioctls on them will file with EIO. To work around this, open a new file descriptor for the VT we want to clean up. Thanks to Ray Strode for help in sorting out the problem and coming up with a fix! https://github.com/systemd/systemd/issues/989
2015-08-18logind: use open_terminal() instead of open()Owen W. Taylor
The open_terminal() function adds retries in case a terminal is in the process of being closed when we open it, and should generally be used to open a terminal. We especially need it for code that a subsequent commit adds that reopens the terminal at session shut-down time; such races would be more likely in that case. Found by Ray Strode.

remove_directory will always return 0 so this can never happen. Besides that, d->path and d are freed so we would end up with a null pointer dereference anyway.

2015-08-17namespace helpers: Allow entering a UID namespaceRichard Maw
To be able to use `systemd-run` or `machinectl login` on a container that is in a private user namespace, the sub-process must have entered the user namespace before connecting to the container's D-Bus, otherwise the UID and GID in the peer credentials are garbage. So we extend namespace_open and namespace_enter to support UID namespaces, and we enter the UID namespace in bus_container_connect_{socket,kernel}. namespace_open will degrade to a no-op if user namespaces are not enabled in the kernel. Special handling is required for the setns call in namespace_enter with a user namespace, since transitioning to your own namespace is forbidden, as it would result in re-entering your user namespace as root. Arguably it may be valid to check this at the call site, rather than inside namespace_enter, but it is less code to do it inside, and if the intention of calling namespace_enter is to *be* in the target namespace, rather than to transition to the target namespace, it is a reasonable approach. The check for whether the user namespace is the same must happen before entering namespaces, as we may not be able to access /proc during the intermediate transition stage. We can't instead attempt to enter the user namespace and then ignore the failure from it being the same namespace, since the error code is not distinct, and we can't compare namespaces while mid-transition.
2015-08-17Bug #944: Deletion of unnecessary checks before a few calls of systemd functionsMarkus Elfring
The following functions return immediately if a null pointer was passed. * calendar_spec_free * link_address_free * manager_free * sd_bus_unref * sd_journal_close * udev_monitor_unref * udev_unref It is therefore not needed that a function caller repeats a corresponding check. This issue was fixed by using the software Coccinelle 1.0.1.
