2016-04-22core,systemctl: add bus API to retrieve processes of a unitLennart Poettering
This adds a new GetProcesses() bus call to the Unit object which returns an array consisting of all PIDs, their process names, as well as their full cgroup paths. This is then used by "systemctl status" to show the per-unit process tree. This has the benefit that the client-side no longer needs to access the cgroupfs directly to show the process tree of a unit. Instead, it now uses this new API, which means it also works if -H or -M are used correctly, as the information from the specific host is used, and not the one from the local system. Fixes: #2945
2016-04-20networkd: bump MTU to 1280 for interfaces which have IPv6 enabled (#3077)Susant Sahani
IPv6 protocol requires a minimum MTU of 1280 bytes on the interface. This fixes #3046. Introduce helper link_ipv6_enabled() to figure out whether IPV6 is enabled. Introduce network_has_static_ipv6_addresses() to find out if any static ipv6 address configured. If IPv6 is not configured on any interface that is SLAAC, DHCPv6 and static IPv6 addresses not configured, then IPv6 will be automatically disabled for that interface, that is we write "1" to /proc/sys/net/ipv6/conf//disable_ipv6.
2016-04-20basic/terminal-util: cache value for colors_enabledZbigniew Jędrzejewski-Szmek
After all it's something that we query over and over. For example, systemctl calls colors_enabled() four times for each failing service. The compiler is unable to optimize those calls away because they (potentially) accesses external and global state through on_tty() and getenv().

We don#t really support systems where XDG_RUNTIME_DIR is not supported for systemd --user. Hence, let's always set our own XDG_RUNTIME_DIR for tests that involve systemd --user, so that we know it is set, and that it doesn't polute the user's actual runtime dir.

2016-04-12core: rework reboot parameter logic a bitLennart Poettering
Always warn if something fails, and clarify that the involved utility functions do so in their name. Drop the REBOOT_PARAM_FILE macro. We don't do this for other flag file paths like this, so don't do this for this one either. The path isn't configurable anyway, hence let's make this easier to read by avoiding this one indirection.
2016-04-12core: be more paranoid when mixing umask and fopen()Lennart Poettering
Let's be extra careful with the umask when we use simple fopen(), as this creates files with 0777 by default.
2016-04-12core: rework how transient unit files and property drop-ins workLennart Poettering
With this change the logic for placing transient unit files and drop-ins generated via "systemctl set-property" is reworked. The latter are now placed in the newly introduced "control" unit file directory. The fomer are now placed in the "transient" unit file directory. Note that the properties originally set when a transient unit was created will be written to and stay in the transient unit file directory, while later changes are done via drop-ins. This is preparation for a later "systemctl revert" addition, where existing drop-ins are flushed out, but the original transient definition is restored.

*.localdomain != localhost
2016-04-04*.localdomain != localhostDavid R. Hedges
".localdomain" is not a reserved suffix (or prefix). I'm not aware of any product expecting *.localdomain to resolve to localhost, however I am aware of at least one product that defaults to ".localdomain" as its DNS suffix provided via DHCP (pfSense). This leads to unexpected results when attempting to access a host that's offline (or a host that's online, when nsswitch.conf is [mis-]configured to have myhostname ahead of DNS). Operate on: localhost (and localhost.) *.localhost (and *.localhost.) localhost.localdomain (and localhost.localdomain.) *.localhost.localdomain (and *.localhost.localdomain.) We should not cover: *.localdomain (nor *.localdomain.) localdomain (nor localdomain.)

The patch is not minimal, but a function to parse size_t is probably going to come in handy in other places, so I think it's nicer to define a proper parsing function than to open-code the cast.

2016-03-26core: update populated event handling in unified hierarchyTejun Heo
Earlier during the development of unified hierarchy, the populated event was reported through by the dedicated "cgroup.populated" file; however, the interface was updated so that it's reported through the "populated" field of "cgroup.events" file. Update populated event handling logic accordingly.
2016-03-26cgroup2: use new fstype for unified hierarchyAlban Crequy
Since Linux v4.4-rc1, __DEVEL__sane_behavior does not exist anymore and is replaced by a new fstype "cgroup2". With this patch, systemd no longer supports the old (unstable) way of doing unified hierarchy with __DEVEL__sane_behavior and systemd now requires Linux v4.4 for unified hierarchy. Non-unified hierarchy is still the default and is unchanged by this patch. https://github.com/torvalds/linux/commit/67e9c74b8a873408c27ac9a8e4c1d1c8d72c93ff

2016-03-17basic/missing: move syscall definitions to basic/missing_syscall.hZbigniew Jędrzejewski-Szmek
We have a bunch of syscall wrapper definitions and it's easier to see that they follow the same pattern if they are not interspersed with other defines. Change the wrappers to be uniform: - if __NR_XXX is not defined, do not bother to call the syscall, and return -1/ENOSYS immediately. - do not check __NR_XXX defines if we detect the symbol as defined, since we don't need them anyway - reindent stuff for readability New file basic/missing_syscall.h is included at the end of missing.h because it might make use of some of the definitions in missing.h.
2016-03-17basic/copy: use copy_file_range()Zbigniew Jędrzejewski-Szmek
For btrfs, c_f_r() is like BTRFS_IOC_CLONE which we already used, but also works when max_bytes is set. We do call copy_bytes in coredump code with max_bytes set, and for large files, so we might see some benefit from using c_f_r() on btrfs. For other filesystems, c_f_r() falls back to do_splice_direct(), the same as sendfile, which we already call, so there shouldn't be much difference. Tested with test-copy and systemd-coredump on Linux 4.3 (w/o c_f_r) and 4.5 (w/ c_f_r).

2016-03-15basic/copy: use sendfile smarterZbigniew Jędrzejewski-Szmek
We called sendfile with 16kb (a.k.a. COPY_BUFFER_SIZE) as the maximum number of bytes to copy. This seems rather inefficient, especially with large files. Instead, call sendfile with a "large" maximum. What "large" max means is a bit tricky: current file offset + max must fit in loff_t. This means that as we call sendfile more than once, we have to lower the max size. With this patch, test-copy calls sendfile twice, e.g.: sendfile(4, 3, NULL, 9223372036854775807) = 738760 sendfile(4, 3, NULL, 9223372036854037047) = 0 The second call is necessary to determine EOF.
2016-03-15time-util: fall back to CLOCK_MONOTONIC if CLOCK_BOOTTIME unsupportedLubomir Rintel
It was added in 2.6.39, and causes an assertion to fail when running in mock hosted on 2.6.23-based RHEL-6: Assertion 'clock_gettime(map_clock_id(clock_id), &ts) == 0' failed at systemd/src/basic/time-util.c:70, function now(). Aborting.
2016-03-14include sys/sysmacros.h in more placesMike Frysinger
Since glibc is moving away from implicitly including sys/sysmacros.h all the time via sys/types.h, include the header directly in more places. This seems to cover most makedev/major/minor usage.
2016-03-10socket_address_listen: do not rely on errno (2)Zbigniew Jędrzejewski-Szmek
We'd still use the invalid errno for a return value. Rework the code to simply return the right error right away.
2016-03-10socket_address_listen - do not rely on errnoPetr Lautrbach
Currently socket_address_listen() calls mac_selinux_bind() to bind a UNIX socket and checks its return value and errno for EADDRINUSE. This is not correct. When there's an SELinux context change made for the new socket, bind() is not the last function called in mac_selinux_bind(). In that case the last call is setfscreatecon() from libselinux which can change errno as it uses access() to check if /proc/thread-self is available. It fails on kernels before 3.17 and errno is set to ENOENT. It's safe to check only the return value at it's set to -errno.
