From c636eed60958875e6499043bcb32f69abf24314c Mon Sep 17 00:00:00 2001 From: Kees Cook Date: Fri, 25 Apr 2025 23:08:42 -0700 Subject: [PATCH] nfp: xsk: Adjust allocation type for nn->dp.xsk_pools In preparation for making the kmalloc family of allocators type aware, we need to make sure that the returned type from the allocation matches the type of the variable being assigned. (Before, the allocator would always return "void *", which can be implicitly cast to any pointer type.) The assigned type "struct xsk_buff_pool **", but the returned type will be "struct xsk_buff_pool ***". These are the same allocation size (pointer size), but the types don't match. Adjust the allocation type to match the assignment.
