From b5d9a834f4fd1b6abfa527ec351c871084dd23a3 Mon Sep 17 00:00:00 2001 From: Dirk van der Merwe Date: Mon, 8 Jul 2019 19:53:13 -0700 Subject: net/tls: don't clear TX resync flag on error Introduce a return code for the tls_dev_resync callback. When the driver TX resync fails, kernel can retry the resync again until it succeeds. This prevents drivers from attempting to offload TLS packets if the connection is known to be out of sync. We don't worry about the RX resync since they will be retried naturally as more encrypted records get received. Signed-off-by: Dirk van der Merwe Reviewed-by: Jakub Kicinski Signed-off-by: David S.
