2015-07-06networkd: be more defensive when writing to ipv4/ipv6 forwarding settingsLennart Poettering
1) never bother with setting the flag for loopback devices 2) if we fail to write the flag due to EROFS (which is likely to happen in containers where /proc/sys is read-only) or any other error, check if the flag already has the right value. If so, don't complain. Closes #469

2015-07-05core: don't mount kdbusfs if not wantedDavid Herrmann
Just like we conditionalize loading kdbus.ko, we should conditionalize mounting kdbusfs. Otherwise, we might run with kdbus if it is builtin, even though the user didn't want this.
2015-07-05networkd: Add support for ipv6 privacy extensionSusant Sahani
This patch add support for ipv6 privacy extensions. The variable /proc/sys/net/ipv6/conf/<if>/use_tempaddr can be changed via the boolean IPv6PrivacyExtensions=[yes/no/prefer-temporary] When true enables privacy extensions, but prefer public addresses over temporary addresses. prefer-temporary prefers temporary adresses over public addresses. Defaults to false. [Match] Name=enp0s25 [Network] IPv6PrivacyExtensions=prefer-temporary

2015-07-04core: harden cgroups-agent forwardingDavid Herrmann
On dbus1, we receive systemd1.Agent signals via the private socket, hence it's trusted. However, on kdbus we receive it on the system bus. We must make sure it's sent by UID=0, otherwise unprivileged users can fake it. Furthermore, never forward broadcasts we sent ourself. This might happen on kdbus, as we forward the message on the same bus we received it on, thus ending up in an endless loop.
2015-07-04busctl: flush stdout after dumping dataDavid Herrmann
Running `busctl monitor` currently buffers data for several seconds / kilobytes before writing stdout. This is highly confusing if you dump in a file, ^C busctl and then end up with a file with data of the last few _seconds_ missing. Fix this by explicitly flushing after each signal.

2015-07-03sd-bus: introduce new sd_bus_flush_close_unref() callLennart Poettering
sd_bus_flush_close_unref() is a call that simply combines sd_bus_flush() (which writes all unwritten messages out) + sd_bus_close() (which terminates the connection, releasing all unread messages) + sd_bus_unref() (which frees the connection). The combination of this call is used pretty frequently in systemd tools right before exiting, and should also be relevant for most external clients, and is hence useful to cover in a call of its own. Previously the combination of the three calls was already done in the _cleanup_bus_close_unref_ macro, but this was only available internally. Also see #327

2015-07-03journal: in persistent mode create /var/log/journal, with all parents.Dimitri John Ledkov
systemd-journald races with systemd-tmpfiles-setup, and hence both are started at about the same time. On a bare-bones system (e.g. with empty /var, or even non-existent /var), systemd-tmpfiles will create /var/log. But it can happen too late, that is systemd-journald already attempted to mkdir /var/log/journal, ignoring the error. Thus failing to create /var/log/journal. One option, without modifiying the dependency graph is to create /var/log/journal directory with parents, when persistent storage has been requested.

richardmaw-codethink/machinectl-import-earlier-than-3-15 util: fall back in rename_noreplace when renameat2 isn't implemented
2015-07-02login: add rule for qemu's pci-bridge-seatGerd Hoffmann
Qemu provides a separate pci-bridge exclusively for multi-seat setups. The normal pci-pci bridge ("-device pci-bridge") has 1b36:0001. The new pci-bridge-seat was specifically added to simplify guest-side multiseat configuration. It is identical to the normal pci-pci bridge, except that it has a different id (1b36:000a) so we can match it and configure multiseating automatically. Make sure we always treat this as separate seat if we detect this, just like other "Pluggable" devices. (David: write commit-message)

2015-07-02sd-bus: don't leak kdbus notificationsDavid Herrmann
When we get notifications from the kernel, we always turn them into synthetic dbus1 messages. This means, we do *not* consume the kdbus message, and as such have to free the offset. Right now, the translation-helpers told the caller that they consumed the message, which is wrong. Fix this by explicitly releasing all kernel messages that are translated.

udev: destroy manager before cleaning environment
2015-07-01udev: destroy manager before cleaning environmentDavid Herrmann
Due to our _cleanup_ usage for the udev manager, it will be destroyed after the "exit:" label has finished. Therefore, it is the last destruction done in main(). This has two side-effects: - mac_selinux is destroyed before the udev manager is, possible causing use-after-free if the manager-cleanup accesses selinux data - log_close() is called *before* the manager is destroyed, possibly re-opening the log if you use --debug (and thus not re-applying the --debug option) Avoid this by moving the manager-handling into a new function called run(). This function will be left before we enter the "exit:" label in main(), hence, the manager object will be destroyed early.

2015-07-01bus-proxy: never apply policy when sending signalsDavid Herrmann
Unlike dbus-daemon, the bus-proxy does not know the receiver of a broadcast (as the kernel has exclusive access on the bus connections). Hence, and "destination=" matches in dbus1 policies cannot be applied. But kdbus does not place any restrictions on *SENDING* broadcasts, anyway. The kernel never returns EPERM to KDBUS_CMD_SEND if KDBUS_MSG_SIGNAL is set. Instead, receiver policies are checked. Hence, stop checking sender policies for signals in bus-proxy and leave it up to the kernel. This fixes some network-manager bus-proxy issues where NM uses weird dst-based matches against interface-based matches. As we cannot perform dst-based matches, our bus-proxy cannot properly implement this policy.
2015-07-01login: re-use VT-sessions if they already existDavid Herrmann
Right now, if you start a session via 'su' or 'sudo' from within a session, we make sure to re-use the existing session instead of creating a new one. We detect this by reading the session of the requesting PID. However, with gnome-terminal running as a busname-unit, and as such running outside the session of the user, this will no longer work. Therefore, this patch makes sure to return the existing session of a VT if you start a new one. This has the side-effect, that you will re-use a session which your PID is not part of. This works fine, but will break assumptions if the parent session dies (and as such close your session even though you think you're part of it). However, this should be perfectly fine. If you run multiple logins on the same session, you should really know what you're doing. The current way of silently accepting it but choosing the last registered session is just weird.

2015-07-01Revert "kmod-setup: don't print warning on -ENOSYS"David Herrmann
This partially reverts commit 78d298bbc57e412574ea35e6e66f562d97fd9ebc. The changed coding-style is kept, but the ENOENT->ENOSYS conversion is reverted. kmod was fixed upstream to no longer return ENOSYS. Also see: https://git.kernel.org/cgit/utils/kernel/kmod/kmod.git/commit/?id=114ec87c85c35a2bd3682f9f891e494127be6fb5 The kmod fix is marked for backport, so no reason to bump the kmod version we depend on.

2015-06-30nspawn: determine_uid_shift before forkingRichard Maw
It is needed in one branch of the fork, but calculated in another branch. Failing to do this means using --private-users without specifying a uid shift always fails because it tries to shift the uid to UID_INVALID.
2015-06-30nspawn: Don't remount with fewer optionsRichard Maw
When we do a MS_BIND mount, it inherits the flags of its parent mount. When we do a remount, it sets the flags to exactly what is specified. If we are in a user namespace then these mount points have their flags locked, so you can't reduce the protection. As a consequence, the default setup of mount_all doesn't work with user namespaces. However if we ensure we add the mount flags of the parent mount when remounting, then we aren't removing mount options, so we aren't trying to unlock an option that we aren't allowed to.
