Subject[PATCH 4.20 137/183] net: socket: make bond ioctls go through compat_ifreq_ioctl()
Date
4.20-stable review patch.  If anyone has any objections, please let me know.

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

From: Johannes Berg <johannes.berg@intel.com>

[ 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.

Cc: stable@vger.kernel.org
Fixes: f92d4fc95341 ("kill bond_ioctl()")
