Subject: Re: [PATCH v2 2/9] powerpc/secvar: Add missing kobject release callback to secvar_ktype
Date: Tue, 27 Oct 2026 22:42:28 +0000 [thread overview]
Message-ID: <sashiko-outbox-187172@kernel.org> (raw)
In-Reply-To: <20261027223847.652884-3-irogers@google.com>
> In add_var(), a struct kobject is dynamically allocated with
> kzalloc_obj() and initialized with secvar_ktype. If kobject_add() or
> sysfs_create_file() fails, kobject_put(kobj) is called to clean up.
> However, secvar_ktype does not define a .release callback, which results
> in a memory leak of kobj (and a pr_debug warning in kobject_cleanup()
> when CONFIG_DEBUG_KOBJECT_RELEASE is enabled).
>
> Provide a secvar_release() callback that calls kfree(kobj).
>
> Fixes: bd5d9c743d38 ("powerpc: expose secure variables to userspace via sysfs")
> Signed-off-by: Ian Rogers <irogers@google.com>
