From 28163868530bf419de6332d5f4c71eac9451dc72 Mon Sep 17 00:00:00 2001 From: Kees Cook Date: Tue, 9 Jun 2020 16:11:29 -0700 Subject: net/compat: Add missing sock updates for SCM_RIGHTS commit d9539752d23283db4692384a634034f451261e29 upstream. Add missed sock updates to compat path via a new helper, which will be used more in coming patches. (The net/core/scm.c code is left as-is here to assist with -stable backports for the compat path.)
