[PATCH] wifi: ath11k: fix qmi memory allocation logic for CALDB region

by Alexandru Gagniuc

Memory region assignment in ath11k_qmi_assign_target_mem_chunk() assumes that: 1. firmware will make a HOST_DDR_REGION_TYPE request, and 2. this request is processed before CALDB_MEM_REGION_TYPE In this case CALDB_MEM_REGION_TYPE, can safely be assigned immediately after the host region. However, if the HOST_DDR_REGION_TYPE request is not made, or the reserved-memory node is not present, then res.start and res.end are 0, and host_ddr_sz remains uninitialized. The physical address should fall back to ATH11K_QMI_CALDB_ADDRESS. That doesn't happen: resource_size(&res) returns 1 for an empty resource, and thus the if clause never takes the fallback path. ab->qmi.target_mem[idx].paddr is assigned the uninitialized value of host_ddr_sz + 0 (res.start). Use "if (res.end > res.start)" for the predicate, which correctly falls back to ATH11K_QMI_CALDB_ADDRESS.

[PATCH V2] mm/slab: ensure all metadata in slab object are word-aligned

by Harry Yoo

When the SLAB_STORE_USER debug flag is used, any metadata placed after the original kmalloc request size (orig_size) is not properly aligned on 64-bit architectures because its type is unsigned int. When both KASAN and SLAB_STORE_USER are enabled, kasan_alloc_meta is misaligned. Note that 64-bit architectures without HAVE_EFFICIENT_UNALIGNED_ACCESS are assumed to require 64-bit accesses to be 64-bit aligned. See HAVE_64BIT_ALIGNED_ACCESS and commit adab66b71abf ("Revert: "ring-buffer: Remove HAVE_64BIT_ALIGNED_ACCESS"") for more details. Because not all architectures support unaligned memory accesses, ensure that all metadata (track, orig_size, kasan_{alloc,free}_meta) in a slab object are word-aligned. struct track, kasan_{alloc,free}_meta are aligned by adding __aligned(__alignof__(unsigned long)). For orig_size, use ALIGN(sizeof(unsigned int), sizeof(unsigned long)) to make clear that its size remains unsigned int but it must be aligned to a word boundary. On 64-bit architectures, this reserves 8 bytes for orig_size, which is acceptable since kmalloc's original request size tracking is intended for debugging rather than production use.
