From: Arnd Bergmann <arnd@arndb.de> mainline inclusion from mainline-v5.5-rc1 commit 9d7bf41fafa5b5ddd4c13eb39446b0045f0a8167 category: bugfix bugzilla: 26804 CVE: NA ------------------------------------- Unlike the normal SIOCOUTQ, SIOCOUTQNSD was never handled in compat mode. Add it to the common socket compat handler along with similar ones. Fixes: 2f4e1b397097 ("tcp: ioctl type SIOCOUTQNSD returns amount of data not sent") Cc: Eric Dumazet <edumazet@google.com> Cc: netdev@vger.kernel.org Cc: "David S.
