btrfs quota beef up and various other unrelated changes
2015-10-22util: allow unbalanced double quote in EXTRACT_QUOTES|EXTRACT_RELAX modeEvgeny Vereshchagin
extract_first_word understands "\'string" but doesn't understand "\"string" fixed this inconsistency.
2015-10-22btrfs: beef-up btrfs support with a limited understanding of quotaLennart Poettering
With this change we understand more than just leaf quota groups for btrfs file systems. Specifically: - When we create a subvolume we can now optionally add the new subvolume to all qgroups its parent subvolume was member of too. Alternatively it is also possible to insert an intermediary quota group between the parent's qgroups and the subvolume's leaf qgroup, which is useful for a concept of "subtree" qgroups, that contain a subvolume and all its children. - The remove logic for subvolumes has been updated to optionally remove any leaf qgroups or "subtree" qgroups, following the logic above. - The snapshot logic for subvolumes has been updated to replicate the original qgroup setup of the source, if it follows the "subtree" design described above. It will not cover qgroup setups that introduce arbitrary qgroups, especially those orthogonal to the subvolume hierarchy. This also tries to be more graceful when setting up /var/lib/machines as btrfs. For example, if mkfs.btrfs is missing we don't even try to set it up as loopback device. Fixes #1559 Fixes #1129

Simplify the call, and add dir_is_populated() as inverse call, in order to make some checks easier to read.

nspawn: skip /sys-as-tmpfs if we don't use private-network
2015-10-20nspawn: skip /sys-as-tmpfs if we don't use private-networkIago López Galeiras
Since v3.11/7dc5dbc ("sysfs: Restrict mounting sysfs"), the kernel doesn't allow mounting sysfs if you don't have CAP_SYS_ADMIN rights over the network namespace. So the mounting /sys as a tmpfs code introduced in d8fc6a000fe21b0c1ba27fbfed8b42d00b349a4b doesn't work with user namespaces if we don't use private-net. The reason is that we mount sysfs inside the container and we're in the network namespace of the host but we don't have CAP_SYS_ADMIN over that namespace. To fix that, we mount /sys as a sysfs (instead of tmpfs) if we don't use private network and ignore the /sys-as-a-tmpfs code if we find that /sys is already mounted as sysfs. Fixes #1555

2015-10-15sd-netlink: refcount multicast groupsTom Gundersen
Track the number of matches installed for a given multicast group, and leave the group once no matches depend on it. In order to handle passed-in sockets that are already members of multicast groups we initialize the refcount based on the membership once we take over the socket. This way we will leave the socket in the state we found it once we finish with it. On kernels that do not fully support reading out the multicast group membership we fall back to never leaving any groups (as before).
2015-10-15btrfs: always remove the per-subvol qgroup when removing a subvolLennart Poettering
btrfs doesn't do that automatically, hence let's do that explicitly each time.

2015-10-08util: minor modernization of vt_disallocate()Lennart Poettering
2015-10-08util: do not reset terminal in acquire_terminal()Lennart Poettering
Before, we'd always reset acquired terminals, which is not really desired, as we expose a setting TTYReset= which is supposed to control whether the TTY is reset or not. Previously that setting would only enable a second resetting of the TTY, which is of course pointless... Hence, move the implicit resetting out of acquire_terminal() and make the callers do it if they need it.
2015-10-08machined: when opening a shell via machined, pass tty fds inLennart Poettering
With this change we'll open the shell's tty right from machined and then pass it to the transient unit we create. This way we make sure the pty is opened exactly as long as the transient service is around, and no longer, and vice versa. This way pty forwarders do not have to deal with EIO problems due to vhangup, as the pty is open all the time from the point we set things up to the point where the service goes away.

2015-10-07util: always enforce O_NOCTTY and O_CLOEXEC in openpt_in_namespace()Lennart Poettering
The child process is shortliving, hence always set O_NOCTTY so that the tty doesn't quickly become controlling TTY and then gives it up again. Also set O_CLOEXEC, because it's cleaner, and doesn't affect the parent anyway.

cache harddisk passwords in the kernel keyring
2015-10-07basic: fix env expansion for strings leading with two dollar signsMichal Schmidt
The way to escape a literal dollar sign is to write "$$". But this does not work right if it's at the beginning of the argument. Fix it.
2015-10-07ask-password: add support for caching passwords in the kernel keyringLennart Poettering
This adds support for caching harddisk passwords in the kernel keyring if it is available, thus supporting caching without Plymouth being around. This is also useful for hooking up "gdm-auto-login" with the collected boot-time harddisk password, in order to support gnome keyring passphrase unlocking via the HDD password, if it is the same. Any passwords added to the kernel keyring this way have a timeout of 2.5min at which time they are purged from the kernel.

2015-10-07smack: label /etc/passwd and friends as '_' smack label when ↵Sangjung Woo
--with-smack-run-label' is enabled systemd-sysusers.service unit creates system users and groups and it could update /etc/passwd, /etc/group, /etc/shadow and /etc/gshadow. Those files should have '_' smack label because of accessibility. However, if systemd has its own smack label using '--with-smack-run-label' configuration, systemd-sysusers process spawned by systemd(pid:1) has its parent smack label and eventually updated files also is set as its parent smack label. This patch fixes that bug by labeling updated files as '_' smack label when --with-smack-run-label' is enabled.

Add support for naming fds for socket activation and more
2015-10-06core: add support for naming file descriptors passed using socket activationLennart Poettering
This adds support for naming file descriptors passed using socket activation. The names are passed in a new $LISTEN_FDNAMES= environment variable, that matches the existign $LISTEN_FDS= one and contains a colon-separated list of names. This also adds support for naming fds submitted to the per-service fd store using FDNAME= in the sd_notify() message. This also adds a new FileDescriptorName= setting for socket unit files to set the name for fds created by socket units. This also adds a new call sd_listen_fds_with_names(), that is similar to sd_listen_fds(), but also returns the names of the fds. systemd-activate gained the new --fdname= switch to specify a name for testing socket activation. This is based on #1247 by Maciej Wereski. Fixes #1247.

2015-10-05hashmap: hash_funcs - make inputs unambiguousTom Gundersen
Make sure all variable-length inputs are properly terminated or that their length is encoded in some way. This avoids ambiguity of adjacent inputs. E.g., in case of a hash function taking two strings, compressing "ab" followed by "c" is now distinct from "a" followed by "bc".
2015-10-05hashmap: refactor hash_funcTom Gundersen
All our hash functions are based on siphash24(), factor out siphash_init() and siphash24_finalize() and pass the siphash state to the hash functions rather than the hash key. This simplifies the hash functions, and in particular makes composition simpler as calling siphash24_compress() repeatedly on separate chunks of input has the same effect as first concatenating the input and then calling siphash23_compress() on the result.

2015-10-01logind: remove warn_melody() logicLennart Poettering
The internal speaker is usually not available on modern latops that support suspend, and even if it is available in the hardware, most distributions turned support for it off in the kernel. And even if it is enabled, it's probably still a bad idea to make use of it for the suspend-failures. If anything a proper sound should be played. Long story short, let's remove support of this anachronism.
