From 86aeda32b887cdaeb0f4b7bfc9971e36377181c7 Mon Sep 17 00:00:00 2001 From: Amit Engel Date: Wed, 27 Oct 2021 09:49:27 +0300 Subject: nvmet-tcp: fix header digest verification Pass the correct length to nvmet_tcp_verify_hdgst, which is the pdu header length. This fixes a wrong behaviour where header digest verification passes although the digest is wrong.
