Currently, tmpfiles runs in two separate services at boot. /dev is
populated by systemd-tmpfiles-setup-dev.service and everything else by
systemd-tmpfiles-setup.service. The former was so far conditionalized by
CAP_SYS_MODULES. The reasoning was that the primary purpose of
populating /dev was to create device nodes based on the static device
node info exported in kernel modules through MODALIAS. And without the
privs to load kernel modules doing so is unnecessary. That thinking is
incomplete however, as there might be reason to create stuff in /dev
outside of the static modalias usecase. Thus, let's drop the
conditionalization to ensure that tmpfiles.d rules are always executed
at least once under all conditions.

In normal use, this allow us to drop dead entries from the cache and reduces
the cache size so that we don't evict entries unnecessarily. The time limit is
there mostly to serve as a guard against malicious logging from many different
PIDs.
This is far from perfect, but should give mostly reasonable values. My
assumption is that if somebody has a few hundred MB of memory, they are
unlikely to have thousands of processes logging. A hundred would already be a
lot. So let's scale the cache size propritionally to the total memory size,
with clamping on both ends.
The formula gives 64 cache entries for each GB of RAM.
First of all let's always log where the errors happen, and not in an
upper stackframe, in all cases. Previously we'd do this somethis one way
and sometimes another, which resulted in sometimes duplicate logging and
sometimes none.
When we cannot activate something due to bad password the kernel gives
us EPERM. Let's uniformly return this EAGAIN, so tha the next password
is tried. (previously this was done in most cases but not in all)
When we get EPERM let's also explicitly indicate that this probably
means the password is simply wrong.
Fixes: #11498
When sd_device_enumerator_add_match_parent() is called
multiple times, then previously set parents are discarded.
This adds device_enumerator_add_match_parent_incremental() to make
sd-device-enumerator scan devices under all specified parents.
Note that for backward compatibility, sd_device_enumerator_add_match_parent()
and udev_enumerate_add_match_parent() still discard previous assignments.
The badge is currently serving a broken image, since Coverity Scan is currently
having an outage. See Issue #11185 for more details. We can restore the badge
by reverting this commit once their service is up again.
procfs_memory_get_current is renamed to procfs_memory_get_used, because
"current" can mean anything, including total memory, used memory, and free
memory, as long as the value is up to date.
No functional change.
Looks to be additions and corrections again. It seems somebody removed
some whitespace in variuos places by mistake, let's hope this gets corrected
upstream. Doing such corrections downstream is not worth the trouble.
Previously, device_copy_properties() copies all properties to both
sd_device::properties and ::properties_db. Thus, on move uevent,
also tentative properties, e.g. DEVPATH or INTERFACE, are stored to
::properties_db, and saved to udev database.
This makes such tentative properties be copied to only ::properties,
and thus not saved to udev database.
Fixes#9426.
