[PATCH v2 0/5] params: harden string ops and allocatio ops

From: Andy Shevchenko
Date: Mon Oct 02 2023 - 08:49:25 EST


A couple of patches are for get the string ops, used in the module,
slightly harden. On top a few cleanups.

Since the main part is rather hardening, I think the Kees' tree is
the best fit for the series, but I'm open for another option(s).

Changelog v2:
- dropped the s*printf() --> sysfs_emit() conversion as it revealed
an issue, i.e. reuse getters with non-page-aligned pointer, which
would be addressed separately
- added cover letter and clarified the possible route for the series
(Luis)

Andy Shevchenko (5):
params: Introduce the param_unknown_fn type
params: Do not go over the limit when getting the string length
params: Use size_add() for kmalloc()
params: Sort headers
params: Fix multi-line comment style
