Merge tag 'asoc-fix-v6.15-rc4' of https://git.kernel.org/pub/scm/linux/kernel/git/broonie/sound into for-linus
ASoC: Fixes for v6.15 A moderately large batch of fixes for v6.15, many driver specific including cleanups for the enabling of the Cirrus KUnit tests and a fix for a nasty crash on resume on AMD systems. We also have one core fix, for an ordering issue between DAPM and DPCM which could leave things incorrectly unpowered.

+/**
+ * DOC: landlock_restrict_self_flags
+ *
+ * **Flags**
+ *
+ * By default, denied accesses originating from programs that sandbox themselves
+ * are logged via the audit subsystem. Such events typically indicate unexpected
+ * behavior, such as bugs or exploitation attempts. However, to avoid excessive
+ * logging, access requests denied by a domain not created by the originating
+ * program are not logged by default. The rationale is that programs should know
+ * their own behavior, but not necessarily the behavior of other programs. This
+ * default configuration is suitable for most programs that sandbox themselves.
+ * For specific use cases, the following flags allow programs to modify this
+ * default logging behavior.
+ *
+ * The %LANDLOCK_RESTRICT_SELF_LOG_SAME_EXEC_OFF and
+ * %LANDLOCK_RESTRICT_SELF_LOG_NEW_EXEC_ON flags apply to the newly created
+ * Landlock domain.
+ *
+ * %LANDLOCK_RESTRICT_SELF_LOG_SAME_EXEC_OFF
+ * Disables logging of denied accesses originating from the thread creating
+ * the Landlock domain, as well as its children, as long as they continue
+ * running the same executable code (i.e., without an intervening
+ * :manpage:`execve(2)` call). This is intended for programs that execute
+ * unknown code without invoking :manpage:`execve(2)`, such as script
+ * interpreters. Programs that only sandbox themselves should not set this
+ * flag, so users can be notified of unauthorized access attempts via system
+ * logs.
+ *
+ * %LANDLOCK_RESTRICT_SELF_LOG_NEW_EXEC_ON
+ * Enables logging of denied accesses after an :manpage:`execve(2)` call,
+ * providing visibility into unauthorized access attempts by newly executed
+ * programs within the created Landlock domain. This flag is recommended
+ * only when all potential executables in the domain are expected to comply
+ * with the access restrictions, as excessive audit log entries could make
+ * it more difficult to identify critical events.
+ *
+ * %LANDLOCK_RESTRICT_SELF_LOG_SUBDOMAINS_OFF
+ * Disables logging of denied accesses originating from nested Landlock
+ * domains created by the caller or its descendants. This flag should be set
+ * according to runtime configuration, not hardcoded, to avoid suppressing
+ * important security events. It is useful for container runtimes or
+ * sandboxing tools that may launch programs which themselves create
+ * Landlock domains and could otherwise generate excessive logs. Unlike
+ * ``LANDLOCK_RESTRICT_SELF_LOG_SAME_EXEC_OFF``, this flag only affects
+ * future nested domains, not the one being created. It can also be used
+ * with a @ruleset_fd value of -1 to mute subdomain logs without creating a
+ * domain.
