crypto: qat - use kcalloc_node() instead of kzalloc_node()
mainline inclusion from mainline-v6.9-rc1 commit 4da3bc65d218605557696109e42cfeee666d601f category: feature bugzilla: https://gitee.com/openeuler/intel-kernel/issues/I9A5BW CVE: N/A Reference: https://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git/commit/?id=4da3bc65d218605557696109e42cfeee666d601f ------------------------------------- As noted in the "Deprecated Interfaces, Language Features, Attributes, and Conventions" documentation [1], size calculations (especially multiplication) should not be performed in memory allocator (or similar) function arguments due to the risk of them overflowing. This could lead to values wrapping around and a smaller allocation being made than the caller was expecting. Using those allocations could lead to linear overflows of heap memory and other misbehaviors. So, use the purpose specific kcalloc_node() function instead of the argument count * size in the kzalloc_node() function.
