H A D | iov.c | 522a9b94 Thu Aug 24 11:47:06 CDT 2023 Philippe Mathieu-Daudé <philmd@redhat.com> util/iov: Avoid dynamic stack allocation
Use autofree heap allocation instead of variable-length array on the stack.
The codebase has very few VLAs, and if we can get rid of them all we can make the compiler error on new additions. This is a defensive measure against security bugs where an on-stack dynamic allocation isn't correctly size-checked (e.g. CVE-2021-3527).
