From 043556d0917a1a5ea58795fe1656a2bce06d2649 Mon Sep 17 00:00:00 2001 From: Jakub Kicinski Date: Fri, 24 May 2019 10:34:33 -0700 Subject: [PATCH] selftests/tls: add test for sleeping even though there is data Add a test which sends 15 bytes of data, and then tries to read 10 byes twice. Previously the second read would sleep indifinitely, since the record was already decrypted and there is only 5 bytes left, not full 10.
