Hi everyone
one functionality that is missing in the new template management mechanism
is the possibility to specify a custom template format per-measurement entry.
Until now, once the template is determined from the kernel configuration
or from the kernel command line parameters 'ima_template'
This patch connects defined templates through a linked list so that it
will be possible to append new descriptors when the functionality
of specifying a custom template in the policy will be introduced.
Template search by name is still performed by iterating over
'defined_templates' array items.
This patch adds a new helper to search a template descriptor by its format.
Also, the old function lookup_template_desc(), which performs the search
by name, has been renamed to lookup_template_desc_by_name().

This patch introduces the ima_get_template_desc() function which returns
a template descriptor depending on the template name and format passed
as arguments. If the first argument is not NULL, the new function
searches an existing template descriptor by name among those defined
and returns it to
This patch adds the support for 'ima_template' and 'ima_template_fmt'
policy options. They allow to define which template and, thus, which
information should be included in measurements entries generated from
events that match other rules' criteria.
With this feature, it is possible to include
This patch replaces calls to ima_template_desc_current() in ima_api.c
and ima_main.c with ima_get_template_desc() as the former function
is called by the latter when passed arguments are both NULL. The patch
also declares the former function as static so that it will not be
longer available
This patch modifies existing IMA functions to retrieve the template name
or format specified in a matched policy rule and provide it to
ima_alloc_init_template(). The latter calls ima_get_template_desc()
to obtain the template descriptor to use for creating a new measurement
entry.

Attached is a merge patch and
With multiple, concurrent readers (each waiting to acquire the
atomic_read_lock mutex), a departing reader may mistakenly reset
minimum_to_wake after a new reader has already set a new value.
Protect the minimum_to_wake reset with the atomic_read_lock critical
section.

A departing reader must restart a flush_to_ldisc() worker _before_
the next reader enters the read loop; this is to avoid the new reader
concluding no more i/o is available and prematurely exiting, when the
old reader simply hasn't re-started the worker yet.

thanks for the explanation.
We use DT overlays to describe the hardware on those boards and, if necessary,
its configuration. For example, if there is a PCIe switch, the overlay would
describe its memory and bus number configuration.
So have your fix

This patchset introduces a number of fixes that are required
for the subsequent patches that add DT overlays support.
Most of them are trivial, adding small bits that are missing,
or exporting functions that were private before.
Changes in V2:

Introduce helper functions for working with the live DT tree.
__of_free_property() frees a dynamically created property
__of_free_tree() recursively frees a device node tree
__of_copy_property() copies a property dynamically
__of_create_empty_node() creates an empty node
