From 44265dc3dae1d373f33f474244b5c9811471080b Mon Sep 17 00:00:00 2001 From: John Baldwin Date: Mon, 15 Nov 2021 11:26:45 -0800 Subject: ktls: Add padding tests for AES-CBC MTE cipher suites. For each AES-CBC MTE cipher suite, test sending records with 1 to 16 bytes of payload. This ensures that all of the potential padding values are covered.
