Merge tag 'audit-pr-20220110' of git://git.kernel.org/pub/scm/linux/kernel/git/pcmoore/audit

Pull audit updates from Paul Moore:
 "Four audit patches for v5.17:

   - Harden the code through additional use of the struct_size() macro
     and zero-length arrays to flexible-array conversions.

   - Ensure that processes which generate userspace audit records are
     not exempt from the kernel's audit throttling when the audit queues
     are being overrun"

* tag 'audit-pr-20220110' of git://git.kernel.org/pub/scm/linux/kernel/git/pcmoore/audit:
  audit: replace zero-length array with flexible-array member
  audit: use struct_size() helper in audit_[send|make]_reply()
  audit: ensure userspace is penalized the same as the kernel when under pressure
  audit: use struct_size() helper in kmalloc()
