* systemd-sleep: always prefer resume device or fileZach Smith2019-10-243-119/+236
| | | | | | | This change checks each swap partition or file reported in /proc/swaps to see if it matches the values configured with resume= and resume_offset= kernel parameters. If a match is found, the matching swap entry is used as the hibernation location regardless of swap priority.

| * basic/arphrd: stop discriminating against NETROM and CISCOZbigniew Jędrzejewski-Szmek2019-09-252-2/+1
| | | | | | | | | | | | ARPHRD_NETROM was excluded, most likely just because it is protocol No. 0, and ARPHRD_CISCO was reported under its alias name "HDLC". Let's just allow defined aliases under the main name.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Our biggest object in libsystemd was a table full of zeros, for the arphdr names. Let's use a switch (which gcc nicely optimizes for us), instead a table with a gap between 826 and 65534: $ ls -l build{,2}/src/basic/a6ba3eb@@basic@sta/arphrd-list.c.o -rw-rw-r--. 1 zbyszek zbyszek 540232 Sep 22 00:29 build/src/basic/a6ba3eb\@\@basic\@sta/arphrd-list.c.o -rw-rw-r--. 1 zbyszek zbyszek 20512 Sep 25 11:56 build2/src/basic/a6ba3eb\@\@basic\@sta/arphrd-list.c.o $ ls -l build{,2}/src/shared/libsystemd-shared-243.so -rwxrwxr-x. 1 zbyszek zbyszek 6774368 Sep 22 00:29 build/src/shared/libsystemd-shared-243.so -rwxrwxr-x. 1 zbyszek zbyszek 6254808 Sep 25 12:16 build2/src/shared/libsystemd-shared-243.so No functional change.

| * | cgroup: introduce support for cgroup v2 CPUSET controllerPavel Hrdina2019-09-2412-3/+236
| |/ | | | | | | | | | | | | | | | | | | | | | | | | | | Introduce support for configuring cpus and mems for processes using cgroup v2 CPUSET controller. This allows users to limit which cpus and memory NUMA nodes can be used by processes to better utilize system resources. The cgroup v2 interfaces to control it are cpuset.cpus and cpuset.mems where the requested configuration is written. However, it doesn't mean that the requested configuration will be actually used as parent cgroup may limit the cpus or mems as well. In order to reflect the real configuration cgroup v2 provides read-only files cpuset.cpus.effective and cpuset.mems.effective which are exported to users as well.

|\ | | | | Clean up ratelimit functions and disable /dev/kmsg ratelimit
| * basic/log: put a ratelimit on our logging to /dev/kmsgZbigniew Jędrzejewski-Szmek2019-09-201-0/+13
| | | | | | | | See the inline comment for details.
| * pid1: disable printk ratelimit in early bootZbigniew Jędrzejewski-Szmek2019-09-203-0/+17
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | We have the problem that many early boot or late shutdown issues are harder to solve than they could be because we have no logs. When journald is not running, messages are redirected to /dev/kmsg. It is also the time when many things happen in a rapid succession, so we tend to hit the kernel printk ratelimit fairly reliably. The end result is that we get no logs from the time where they would be most useful. Thus let's disable the kernels ratelimit. Once the system is up and running, the ratelimit is not a problem. But during normal runtime, things also log to journald, and not to /dev/kmsg, so the ratelimit is not useful. Hence, there doesn't seem to be much point in trying to restore the ratelimit after boot is finished and journald is up and running. See kernel's commit 750afe7babd117daabebf4855da18e4418ea845e for the description of the kenrel interface. Our setting has lower precedence than explicit configuration on the kenrel command line.
| * tree-wide: say "ratelimit" not "rate_limit"Zbigniew Jędrzejewski-Szmek2019-09-2017-92/+92
| | | | | | | | | | | | "ratelimit" is a real word, so we don't need to use the other form anywhere. We had both forms in various places, let's standarize on the shorter and more correct one.
| * pid1: rename start_limit to start_ratelimitZbigniew Jędrzejewski-Szmek2019-09-205-17/+17
| | | | | | | | | | This way it is clearer what the type is. We also have auto_stop_ratelimit adjacent, and it feels ugly to have a different suffix for those two.
| * Drop RATELIMIT macrosZbigniew Jędrzejewski-Szmek2019-09-2011-45/+20
| | | | | | | | | | Using plain structure initialization is both shorter _and_ more clearer. We get type safety for free.
| * pid1: do not warn if /run/systemd/relabel-extra.d/ doesn't existZbigniew Jędrzejewski-Szmek2019-09-191-1/+2
| | | | | | | | After all, that is the expected state.

* | | | sd-radv: if lifetime < SD_RADV_DEFAULT_MAX_TIMEOUT_USEC, adjust timeout (#13491)Georg Müller2019-09-201-0/+11
|/ / / | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The RFC states that lifetime (AdvDefaultLifetime) must be at least MaxRtrAdvInterval (which more or less corresponds to SD_RADV_DEFAULT_MAX_TIMEOUT_USEC in systemd). To fulfill this limit, virtually lower MaxRtrAdvInterval and MinRtrAdvInterval accordingly. Also check that min is not lower than 3s and max is not lower than 4s.
