[PATCH 4.20 137/183] net: socket: make bond ioctls go through compat_ifreq_ioctl()

From: Greg Kroah-Hartman
Date: Mon Feb 25 2019 - 16:34:56 EST


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

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

From: Johannes Berg <johannes.berg@xxxxxxxxx>

[ Upstream commit 98406133dd9cb9f195676eab540c270dceca879a ]

Same story as before, these use struct ifreq and thus need
to be read with the shorter version to not cause faults.
