2016-02-10tree-wide: remove Emacs lines from all filesDaniel Mack
This should be handled fine now by .dir-locals.el, so need to carry that stuff in every file.
2016-01-27utf8.[ch] et al: use char32_t and char16_t instead of int, int32_t, int16_tShawn Landden
rework C11 utf8.[ch] to use char32_t instead of uint32_t when referring to unicode chars, to make things more expressive. [ @zonque: * rebased to current master * use AC_CHECK_DECLS to detect availibility of char{16,32}_t * make utf8_encoded_to_unichar() return int ]
2016-01-25resolved: when checking whether a link is relevant, check kernel operstateLennart Poettering
This mimics what networkd is doing to detect a carrier.

This small addition fixes the issues #1982 and #2242. IPv6PrivacyExtension now works as expected even when a RA is received.
2016-01-12capabilities: added support for ambient capabilities.Ismo Puustinen
This patch adds support for ambient capabilities in service files. The idea with ambient capabilities is that the execed processes can run with non-root user and get some inherited capabilities, without having any need to add the capabilities to the executable file. You need at least Linux 4.3 to use ambient capabilities. SecureBit keep-caps is automatically added when you use ambient capabilities and wish to change the user. An example system service file might look like this: [Unit] Description=Service for testing caps [Service] ExecStart=/usr/bin/sleep 10000 User=nobody AmbientCapabilities=CAP_NET_ADMIN CAP_NET_RAW After starting the service it has these capabilities: CapInh: 0000000000003000 CapPrm: 0000000000003000 CapEff: 0000000000003000 CapBnd: 0000003fffffffff CapAmb: 0000000000003000
2015-12-31core: socket options fix SCTP_NODELAYSusant Sahani
SCTP_NODELAY is diffrent to TCP_NODELAY. Apply proper options in case of SCTP.

2015-11-11sd-netlink: types - let tables be sized implicitlyTom Gundersen
This way we do not rely on the size MAX* constants from the kernel headers, as these will be out-of-sync in case we have old headers and new defines in missing.h.
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

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.
2015-10-07ask-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.

Add fallback for kcmp() in case __NR_kcmp is undefined

IA64 is missing this syscall as of linux-4.2. This works around it until the necessary kernel patch gets merged.

2015-09-01core: unified cgroup hierarchy supportLennart Poettering
This patch set adds full support the new unified cgroup hierarchy logic of modern kernels. A new kernel command line option "systemd.unified_cgroup_hierarchy=1" is added. If specified the unified hierarchy is mounted to /sys/fs/cgroup instead of a tmpfs. No further hierarchies are mounted. The kernel command line option defaults to off. We can turn it on by default as soon as the kernel's APIs regarding this are stabilized (but even then downstream distros might want to turn this off, as this will break any tools that access cgroupfs directly). It is possibly to choose for each boot individually whether the unified or the legacy hierarchy is used. nspawn will by default provide the legacy hierarchy to containers if the host is using it, and the unified otherwise. However it is possible to run containers with the unified hierarchy on a legacy host and vice versa, by setting the $UNIFIED_CGROUP_HIERARCHY environment variable for nspawn to 1 or 0, respectively. The unified hierarchy provides reliable cgroup empty notifications for the first time, via inotify. To make use of this we maintain one manager-wide inotify fd, and each cgroup to it. This patch also removes cg_delete() which is unused now. On kernel 4.2 only the "memory" controller is compatible with the unified hierarchy, hence that's the only controller systemd exposes when booted in unified heirarchy mode. This introduces a new enum for enumerating supported controllers, plus a related enum for the mask bits mapping to it. The core is changed to make use of this everywhere. This moves PID 1 into a new "init.scope" implicit scope unit in the root slice. This is necessary since on the unified hierarchy cgroups may either contain subgroups or processes but not both. PID 1 hence has to move out of the root cgroup (strictly speaking the root cgroup is the only one where processes and subgroups are still allowed, but in order to support containers nicey, we move PID 1 into the new scope in all cases.) This new unit is also used on legacy hierarchy setups. It's actually pretty useful on all systems, as it can then be used to filter journal messages coming from PID 1, and so on. The root slice ("-.slice") is now implicitly created and started (and does not require a unit file on disk anymore), since that's where "init.scope" is located and the slice needs to be started before the scope can. To check whether we are in unified or legacy hierarchy mode we use statfs() on /sys/fs/cgroup. If the .f_type field reports tmpfs we are in legacy mode, if it reports cgroupfs we are in unified mode. This patch set carefuly makes sure that cgls and cgtop continue to work as desired. When invoking nspawn as a service it will implicitly create two subcgroups in the cgroup it is using, one to move the nspawn process into, the other to move the actual container processes into. This is done because of the requirement that cgroups may either contain processes or other subgroups.

Alpha does not have a getpid syscall, but rather has getxpid to match OSF/1.
