From c98df489ad5c9331bf80c83f4fa2d45bbf0f93be Mon Sep 17 00:00:00 2001

Subject: [PATCH 5001/5001] 99-systemd.rules: rework SYSTEMD_READY logic for
device mapper
Device mapper devices are set up in multiple steps. The first step, which
generates the initial "add" event, only creates an empty container, which is
useless for higher layers. SYSTEMD_READY should be set to 0 on this event to
avoid premature device activation.
The event that matters is the "activation" event: the first "change" event on
which DM_UDEV_DISABLE_OTHER_RULES_FLAG=1 is not set. When this event arrives,
the device is ready for being scanned by blkid and similar tools, and for being
activated by systemd.
Intermittent events with DM_UDEV_DISABLE_OTHER_RULES_FLAG=1 should be ignored
as far as systemd or higher-level block layers are concerned. Previous device
properties and symlinks should be preserved: the device shouldn't be scanned or
activated, but shouldn't be deactivated, either. In particular, SYSTEM_READY
shouldn't be set to 0 if it wasn't set before, because that might cause mounted
file systems to be unmounted. Such intermittent events may occur any time,
before or after the "activation" event.
DM_UDEV_DISABLE_OTHER_RULES_FLAG=1 can have multiple reasons. One possible reason
is that the device is suspended. There are other reasons that depend on the
device-mapper subsystem (LVM, multipath, dm-crypt, etc.).
The current systemd rule set
1) sets SYSTEMD_READY=0 if DM_UDEV_DISABLE_OTHER_RULES_FLAG is set in "add"
events;
2) imports SYSTEMD_READY from the udev db if DM_SUSPENDED is set, and jumps to systemd_end;
3) sets SYSTEMD_READY=1, otherwise.
This logic has several flaws:
* 1) can cause file systems to be unmounted if an coldplug event arrives while
a file system is suspended. This rule shouldn't be applied for coldplug events
or in general, "synthetic" add events;
* 2) evaluates DM_SUSPENDED=1, which is a device-mapper internal property.
It's wrong to infer that a device is accessible if DM_SUSPENDED=0.
The jump to systemd_end may cause properties and/or symlinks to be lost;
* 3) is superfluous, because SYSTEMD_READY=1 is equivalent with SYSTEMD_READY
being unset, and can create the wrong impression that the device was explicitly
activated.
This patch fixes the logic as follows:
- apply 1) only if DM_NAME is empty, which is only the case for the first
"genuine add" event;
- change 2) to use DM_UDEV_DISABLE_OTHER_RULES_FLAG instead of DM_SUSPENDED,
and remove the GOTO directive;
- remove 3).
Fixes: b7cf1b6 ("udev: use SYSTEMD_READY to mask uninitialized DM devices")
Fixes: 35a6750 ("rules: set SYSTEMD_READY=0 on DM_UDEV_DISABLE_OTHER_RULES_FLAG=1 only with ADD event (#2747)")

Subject: [PATCH 5003/5011] cgroup: rename TasksMax structure to CGroupTasksMax
Almost all our enums/structs/funcs carry the CGroup prefix if they are
defined in cgroup.h, TasksMax so far does not, even though it is
exclusively used in cgroup context.
Change that.

EffectiveMemoryHigh= and EffectiveTasksMax= properties
Users become perplexed when they run their workload in a unit with no
explicit limits configured (moreover, listing the limit property would
even show it's infinity) but they experience unexpected resource
limitation.
The memory and pid limits come as the most visible, therefore add new
unit read-only properties:
- EffectiveMemoryMax=,
- EffectiveMemoryHigh=,
- EffectiveTasksMax=.
These properties represent the most stringent limit systemd is aware of
for the given unit -- and that is typically(*) the effective value.
Implement the properties by simply traversing all parents in the
leaf-slice tree and picking the minimum value. Note that effective
limits are thus defined even for units that don't enable explicit
accounting (because of the hierarchy).
(*) The evasive case is when systemd runs in a cgroupns and cannot
reason about outer setup. Complete solution would need kernel support.

Global resource (whole system or root cg's (e.g. in a container)) is
also a well-defined limit for memory and tasks, take it into account
when calculating effective limits.

# The order of the units being restarted is important here because there's

# atomically. Therefore systemctl will create 3 restart jobs that can be handled

# then starting them again will fail as the service is still active hence the
# sockets held by udevd. However if the restart job for udevd is handled first,

# correctly by stopping the service then the sockets and then by starting the
