[PATCH 6.18 0542/1611] net: remove addr_len argument of recvmsg() handlers

[Greg Kroah-Hartman <gregkh@linuxfoundation.org>]

6.18-stable review patch.  If anyone has any objections, please let me know.

------------------

From: Eric Dumazet <edumazet@google.com>

[ Upstream commit 8341c989ac77d712c7d6e2bce29e8a4bcb2eeae4 ]

Use msg->msg_namelen as a place holder instead of a
temporary variable, notably in inet[6]_recvmsg().

This removes stack canaries and allows tail-calls.
