From 7608a971fdeb4c3eefa522d1bfe8d4bc6b2481cc Mon Sep 17 00:00:00 2001 From: Sabrina Dubroca Date: Mon, 25 Mar 2024 16:56:45 +0100 Subject: tls: recv: process_rx_list shouldn't use an offset with kvec Only MSG_PEEK needs to copy from an offset during the final process_rx_list call, because the bytes we copied at the beginning of tls_sw_recvmsg were left on the rx_list. In the KVEC case, we removed data from the rx_list as we were copying it, so there's no need to use an offset, just like in the normal case.
