From 531ef54548372c6b5b3eb5e5f264119b01a85ddb Mon Sep 17 00:00:00 2001 From: Chen Zhou Date: Thu, 12 Nov 2020 21:53:32 +0800 Subject: [PATCH] selinux: Fix error return code in sel_ib_pkey_sid_slow() commit c350f8bea271782e2733419bd2ab9bf4ec2051ef upstream. Fix to return a negative error code from the error handling case instead of 0 in function sel_ib_pkey_sid_slow(), as done elsewhere in this function.
