net/compat: Add missing sock updates for SCM_RIGHTS
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.) Cc: Christoph Hellwig <hch@lst.de> Cc: Sargun Dhillon <sargun@sargun.me> Cc: Jakub Kicinski <kuba@kernel.org> Cc: stable@vger.kernel.org Fixes: 48a87cc26c13 ("net: netprio: fd passed in SCM_RIGHTS datagram not set correctly") Fixes: d84295067fc7 ("net: net_cls: fd passed in SCM_RIGHTS datagram not set correctly") Acked-by: Christian Brauner <christian.brauner@ubuntu.com> Signed-off-by: Kees Cook <keescook@chromium.org>
