+From aec4fe7e3c4d18cd5d0f98168df5884a141c6b69 Mon Sep 17 00:00:00 2001
+From: Simo Sorce <simo@redhat.com>

+Subject: [PATCH] Fix i686 build failures in cipher.c
+
+Update AEAD functions to use CK_ULONG pointers for lengths and
+introduce a temporary size_t variable for OSSL_PARAM calls. This
+corrects pointer type mismatches that caused build failures in
+Fedora Rawhide i686 scratch builds.
+
+Upstream-Status: Backport [aec4fe7e3c4d18cd5d0f98168df5884a141c6b69]
