updatehub: Require peer verification with DTLS

DTLS without peer verification offers no security whatsoever (and is
arguably worse than not using DTLS in the first place).

Change the verification option to require this peer verification.  To
use this, it may be necessary to install and use a root certificate.

-# Background
-
-The [TSC Project Roles] defines the main roles for the Zephyr Project, including
-Maintainer, Collaborator, and Contributor.
-
-By default anyone that contributes code or documentation is a Contributor, but
-with the lowest [GitHub Permission Level] of Read. For example, Contributors
-with Read permission do not have the permission to add reviewers to a pull
-request.
-
-Use this template to nominate a GitHub user for the Contributor role with
-Triage permission level, which allows the user to add reviewers to a pull
-request and be added as a reviewer by other users.
-
-# Nomination
-
-## GitHub User
-
-Provide the following information about the GitHub user:
-
-1. Full Name
-1. GitHub username
-1. Organization (optional)
-
-## Supporting Documents
-
-Add links to 3-5 GitHub pull requests, in the Zephyr project, authored or
-reviewed by the GitHub user that demonstrate the user's dedication to the
-Zephyr project.

-
-## Origin
-
-Name of project hosting the original open source code
-Provide a link to the source
-
-## Purpose
-
-Brief description of what this software does
-
-## Mode of integration
-
-Describe whether you'd like to integrate this external component in the main tree
-or as a module, and why. If the mode of integration is a module, suggest a
-repository name for the module
-
-## Maintainership
-
-List the person(s) that will be maintaining the integration of this external code
-for the foreseeable future. Please use GitHub IDs to identify them. You can

-
-## Pull Request
-
-Pull request (if any) with the actual implementation of the integration, be it
-in the main tree or as a module (pointing to your own fork for now). Make sure
-the PR is correctly labeled as "DNM"
-
-## Description
-
-Long description that will help reviewers discuss suitability of the
-component to solve the problem at hand (there may be a better options
-available.)
-
-What is its primary functionality (e.g., SQLLite is a lightweight
-database)?
-
-What problem are you trying to solve? (e.g., a state store is
-required to maintain ...)
-
-Why is this the right component to solve it (e.g., SQLite is small,
-easy to use, and has a very liberal license.)
-
-## Dependencies
-
-What other components does this package depend on?
-
-Will the Zephyr project have a direct dependency on the component, or
-will it be included via an abstraction layer with this component as a
-replaceable implementation?

+This directory contains configuration files to ignore errors found in
+the build and test process which are known to the developers and for
+now can be safely ignored.
+
+To use:
+
+ $ cd zephyr
+ $ make SOMETHING >& result
+ $ scripts/filter-known-issues.py result
+
+It is included in the source tree so if anyone has to submit anything
+that triggers some kind of error that is a false positive, it can
+include the "ignore me" file, properly documented.
+
+Each file can contain one or more multiline Python regular expressions
+(https://docs.python.org/2/library/re.html#regular-expression-syntax)
+that match an error message. Multiple regular expressions are
+separated by comment blocks (that start with #). Note that an empty
+line still is considered part of the multiline regular expression.
+
+For example
+
+---beginning---
+#
+# This testcase always fails, pending fix ZEP-1234
+#
+.*/tests/kernel/grumpy .* FAIL
+#
+# Documentation issue, masks:
+#
+# /home/e/inaky/z/kernel.git/doc/api/io_interfaces.rst:28: WARNING: Invalid definition: Expected identifier in nested name. [error at 19]
+#  struct dev_config::@65  dev_config::bits
+#  -------------------^
+#
+^(?P<filename>.+/doc/api/io_interfaces.rst):(?P<lineno>[0-9]+): WARNING: Invalid definition: Expected identifier in nested name. \[error at [0-9]+]
+^\s+struct dev_config::@[0-9]+  dev_config::bits.*
+^\s+-+\^
+---end---
+
+Note you want to:
+
+- use relateive paths; instead of
+  /home/me/mydir/zephyr/something/somewhere.c you will want
+  ^.*/something/somewhere.c (as they will depend on where it is being
+  built)
+
+- Replace line numbers with [0-9]+, as they will change
+
+- (?P<filename>[-._/\w]+/something/somewhere.c) saves the match on
+  that file path in a "variable" called 'filename' that later you can
+  match with (?P=filename) if you want to match multiple lines of the
+  same error message.
+
+Can get really twisted and interesting in terms of regexps; they are
+powerful, so start small :)

+ * This function performs an assessment whether a memory fault (on a
+ * given memory address) is the result of stack memory corruption of
+ * the current thread.
  *
- * When called, we know at this point that we received an ARC
- * protection violation, with any cause code, with the protection access
- * error either "MPU" or "Secure MPU". In other words, an MPU fault of
- * some kind. Need to determine whether this is a general MPU access
- * exception or the specific case of a stack overflow.
+ * Thread stack corruption for supervisor threads or user threads in
+ * privilege mode (when User Space is supported) is reported upon an
+ * attempt to access the stack guard area (if MPU Stack Guard feature
+ * is supported). Additionally the current thread stack pointer
+ * must be pointing inside or below the guard area.
+ *
+ * Thread stack corruption for user threads in user mode is reported,
+ * if the current stack pointer is pointing below the start of the current
+ * thread's stack.
+ *
+ * Notes:
+ * - we assume a fully descending stack,
+ * - we assume a stacking error has occurred,
+ * - the function shall be called when handling MPU privilege violation
+ *
+ * If stack corruption is detected, the function returns the lowest
+ * allowed address where the Stack Pointer can safely point to, to
+ * prevent from errors when un-stacking the corrupted stack frame
+ * upon exception return.
  *
  * @param fault_addr memory address on which memory access violation
  *                   has been reported.
