The previous minimum required version 5.4 will be EOL on 2025-12.
Let's bump the required minimum kernel version to the next LTS release 5.10
(released on 2020-12-13, EOL on 2026-12, CIP support until 2031-01).
The new recommended baseline 5.14 is the version that CentOS 9 uses.
CentOS 9 will EOL on 2027-05.
See also #38608.
manager_varlink_init_resolve_hook and manager_varlink_init_userdb are very
similar, but one didn't set a description and the other one had an error
message which didn't print the offending path.
Define constants for the paths, and also change other similar constants
to have slightly shorter names. (It's an "address" and "path", but we don't
need to have both parts in the name, esp. that it makes the name very long.)
constants.h defines a bunch of constants that use macros from
time-util.h, so add the needed include. To avoid cyclic dependencies,
we move the HAS_FEATURE_MEMORY_SANITIZER and HAS_FEATURE_ADDRESS_SANITIZER
logic to macro.h and get rid of the constants.h include there.
The rest of this commit is adding missing constants.h includes where
needed due to it being removed from macro.h.
As requested, a list of kernel version to feature mapping
for kernels older than minimum baseline is also included,
in order to ease potential backport work.

We define *_SLOW_BUS_CALL_TIMEOUT in each component's
own file too. This one is no different and doesn't need
to be in constants.h IMO.
Let's add a new "plymouth-util.c" module with helpers for talking to
plymouth. We so far had three places for this, let's unify the code
doing this a bit.
So, unfortunately oomd uses "io.system." rather than "io.systemd." as
prefix for its sockets. This is a mistake, and doesn't match the
Varlink interface naming or anything else in oomd.
hence, let's fix that.
Given that this is an internal protocol between PID1 and oomd let's
simply change this without retaining compat.
All daemons use a similar scheme to read their main config files and theirs
drop-ins. The main config files are always stored in /etc/systemd directory and
it's easy enough to construct the name of the drop-in directories based on the
name of the main config file.
Hence the new helper does that internally, which allows to reduce and simplify
the args passed previously to config_parse_many_nulstr().
Besides the overall code simplification it results:
16 files changed, 87 insertions(+), 159 deletions(-)
it allows to identify clearly the locations in the code where configuration
files are parsed.
Config options are -Ddefault-timeout-sec= and -Ddefault-user-timeout-sec=.
Existing -Dupdate-helper-user-timeout= is renamed to -Dupdate-helper-user-timeout-sec=
for consistency. All three options take an integer value in seconds. The
renaming and type-change of the option is a small compat break, but it's just
at compile time and result in a clear error message. I also doubt that anyone was
actually using the option.
This commit separates the user manager timeouts, but keeps them unchanged at 90 s.
The timeout for the user manager is set to 4/3*user-timeout, which means that it
is still 120 s.
Fedora wants to experiment with lower timeouts, but doing this via a patch would
be annoying and more work than necessary. Let's make this easy to configure.
The name "def.h" originates from before the rule of "no needless abbreviations"
was established. Let's rename the file to clarify that it contains a collection
of various semi-related constants.
