Vlastimil Babka 90e9b23a60 Merge branch 'slab/for-6.2/kmalloc_redzone' into slab/for-next ... kmalloc() redzone improvements by Feng Tang From cover letter [1]: kmalloc's API family is critical for mm, and one of its nature is that it will round up the request size to a fixed one (mostly power of 2). When user requests memory for '2^n + 1' bytes, actually 2^(n+1) bytes could be allocated, so there is an extra space than what is originally requested. This patchset tries to extend the redzone sanity check to the extra kmalloced buffer than requested, to better detect un-legitimate access to it. (depends on SLAB_STORE_USER & SLAB_RED_ZONE) [1] https://lore.kernel.org/all/20221021032405.1825078-1-feng.tang@intel.com/		2022-11-21 10:36:09 +01:00
