2016-05-29util-lib: Add sparc64 support for process creation (#3348)Michael Karcher
The current raw_clone function takes two arguments, the cloning flags and a pointer to the stack for the cloned child. The raw cloning without passing a "thread main" function does not make sense if a new stack is specified, as it returns in both the parent and the child, which will fail in the child as the stack is virgin. All uses of raw_clone indeed pass NULL for the stack pointer which indicates that both processes should share the stack address (so you better don't pass CLONE_VM). This commit refactors the code to not require the caller to pass the stack address, as NULL is the only sensible option. It also adds the magic code needed to make raw_clone work on sparc64, which does not return 0 in %o0 for the child, but indicates the child process by setting %o1 to non-zero. This refactoring is not plain aesthetic, because non-NULL stack addresses need to get mangled before being passed to the clone syscall (you have to apply STACK_BIAS), whereas NULL must not be mangled. Implementing the conditional mangling of the stack address would needlessly complicate the code. raw_clone is moved to a separete header, because the burden of including the assert machinery and sched.h shouldn't be applied to every user of missing_syscalls.h

2016-05-28core/unit: append newline when writing drop insZbigniew Jędrzejewski-Szmek
unit_write_drop_in{,_private}{,_format} are all affected. We already append a header to the file (and section markers), so those functions can only be used to write a whole file at once. Including the newline at the end feels natural. After this commit newlines will be duplicated. They will be removed in subsequent commit. Also, rewrap the "autogenerated" header to fit within 80 columns.

2016-05-28networkd: disable IPv6 for bridge slaveTom Yan
If an interface is managed as a bridge slave, we don't want any IP configuration for it. Therefore, disable IPv6 in such case.
2016-05-28networkd: unset master if not enslaved with networkdTom Yan
When we manage an interface with networkd but not as a slave (i.e. no `Bridge=` or `Bond=` set in its .network), we do not want it to remain slaved.

2016-05-27core: add cgroup memory controller support on the unified hierarchy (#3315)Tejun Heo
On the unified hierarchy, memory controller implements three control knobs - low, high and max which enables more useable and versatile control over memory usage. This patch implements support for the three control knobs. * MemoryLow, MemoryHigh and MemoryMax are added for memory.low, memory.high and memory.max, respectively. * As all absolute limits on the unified hierarchy use "max" for no limit, make memory limit parse functions accept "max" in addition to "infinity" and document "max" for the new knobs. * Implement compatibility translation between MemoryMax and MemoryLimit. v2: - Fixed missing else's in config_parse_memory_limit(). - Fixed missing newline when writing out drop-ins. - Coding style updates to use "val > 0" instead of "val". - Minor updates to documentation.

2016-05-26nspawn: split out seccomp call into nspawn-seccomp.[ch]Djalal Harouni
Split seccomp into nspawn-seccomp.[ch]. Currently there are no changes, but this will make it easy in the future to share or use the seccomp logic from systemd core.

2016-05-26{machine,system}ctl: always pass &changes and &n_changes (#3350)Christian Hesse
We have to pass addresses of changes and n_changes to bus_deserialize_and_dump_unit_file_changes(). Otherwise we are hit by missing information (subsequent calls to unit_file_changes_add() to not add anything). Also prevent null pointer dereference in bus_deserialize_and_dump_unit_file_changes() by asserting. Fixes #3339

2016-05-26sd-ndisc: small coding style fixesLennart Poettering
Let's use usec_t internally always, when dealing with time values. Let's use uint8_t* pointers if we are dealing with generic byte pointers.
2016-05-26sd-ndisc: add more whitespaceLennart Poettering
Whitespace doesn't hurt and helps structuring things.

2016-05-26sd-ndisc: rework size checking in ndisc_ra_parse()Lennart Poettering
Let's better check the size before we subtract. Also, let's change the size argument to size_t, as it cannot be signed anyway. Finally, use EBADMSG for indicating invalid packets, like we do everywhere else.

2016-05-26sd-ndisc: append "event_source" to event source objects stored in structuresLennart Poettering
Otherwise it gets too confusing whether "timeout" refers to an event source or just a timeout time specification.

Also make use of it where appropriate.
2016-05-26sd-ndisc: use the right object to pass to log_ndisc()Lennart Poettering
There's no "client" object, in both cases. There's only "nd". This wasn't noticed before, as the context object is currently not actually used by the log macros.

2016-05-26ipv4acd: rename "ll" parameter to "acd" everywhereLennart Poettering

2016-05-26sd-ipv4acd: drop IPV4ACD_NETWORK definitionLennart Poettering
Appears to be a copy/paste mistake from sd-ipv4ll. Let's get rid of this.
2016-05-26ipv4acd: rework how we pick ipv4ll addressesLennart Poettering
Let's make the seed actually work as stable seed, and use siphash24 to generate the series of addresses, instead of the opaque libc random_r(). This not only makes the seed truly work as stable, portable seed, but also makes the code quite a bit shorter, and removes a couple of memory allocations.
2016-05-26ipv4ll: change "seed" parameter to be uint64_tLennart Poettering
Let's make clear this always has the same size, since otherwise it's not useful for reproducible runs, which this is really about however.

2016-05-26ipv4acd: normalize time types to usec_tLennart Poettering
We try to stick to usec_t for encoding time information, do that here too. In particular, get rid of "int" second specifications, since signed timespans are a weird thing.

2016-05-26ipv4acd: introduce new "started" stateLennart Poettering
This state is active immediately after the state engine was started, but before the first timer hits. This way multiple _start() invocations on the same object are always detected correctly.
