Subject: [PATCH 2/3] Feature: scheduler: Check the CIB feature set in
cluster_status.
This adds the check that was previously only in cib_perform_op to the
scheduler code, ensuring that any daemon or tool that calls the
scheduler will check that the feature set in the CIB is supported.

Date: Wed, 10 Jan 2024 14:56:36 -0500
Subject: [PATCH 3/3] Low: libcib: Do not check CIB feature set for files in
cib_perform_op.
This is related to the previous feature for transferring schema files to
older remote nodes. In that case, the newer schema files may also have
a newer feature set than the node supports, so the transferred files are
still not usable.
However, the feature set only matters for the scheduler, not for most
command line tools (obviously, crm_simulate would still care). So in
those cases, we can just disable the feature set check if the CIB was
read in from a file. For the scheduler, the check is still performed as
part of cluster_status.

Subject: [PATCH 2/5] Fix: pacemaker-attrd: sync utilization attributes to
peers correctly
Include the set type with attribute syncs.
Previously, utilization attributes would have the correct set_type on the node
where they were set, but peers would store it as a regular node attribute. If
one of those peers became writer, the attribute would get written to the wrong
set.

Subject: [PATCH] Fix: tools: crm_attribute emits garbage for --node localhost
or auto
This happens because pcmk__node_attr_target() returns its argument if
its argument is NULL, "auto", or "localhost" and no relevant environment
variables are found. Then crm_attribute frees the return value, makes a
copy of it, and assigns it back to options.dest_uname.
The fix is to check whether the return value is equal to the argument.
Fixes RHEL-23065

Subject: [PATCH] Refactor: various: Don't set cluster-layer node ID as XML ID
Currently, we call the pcmk__xe_set_id() function using a stringified
version of the numeric cluster-layer node ID. However, pcmk__xe_set_id()
tries to sanitize its input to a valid XML ID. An XML ID cannot begin
with a digit.
crm_xml_set_id() does not sanitize comprehensively, and in particular,
it does not care whether its argument begins with a digit. So the
current code doesn't cause a problem.
Still, as a best practice, set the PCMK_XA_ID attribute using
crm_xml_add_ll() instead.

Subject: [PATCH] Fix: tools: crm_node -i must initialize nodeid before passing
pointer
This is a regression introduced in 2.1.7 via a27f099.
Currently, crm_node -i passes a pointer to the uninitialized uint32_t
nodeid variable, to pcmk__query_node_info(). Since the pointer is
non-NULL, pcmk__query_node_info() dereferences it. Whatever garbage
value resides there gets passed as the ID to query.
The controller parses the node ID from the request as an int. If the
garbage value is greater than INT_MAX, it overflows to a negative int
value, and the controller (in handle_node_info_request()) defaults it to
0. In that case, there's no problem: we search for the local node name
instead of the garbage node ID.
If the garbage value is less than or equal to INT_MAX, we search for it
directly. We won't find a matching node unless one happens to exist with
that garbage node ID. In the case of no match, crm_node -i outputs "Node
is not known to cluster" instead of the local node's cluster-layer ID.
Thanks to Artur Novik for the report:
