["Ryota Ozaki" <ozaki-r%netbsd.org@localhost>]

Module Name:    src
Committed By:   ozaki-r
Date:           Wed Nov 22 03:03:18 UTC 2017

Modified Files:
        src/sys/kern: sys_socket.c
        src/sys/net: if.c if.h if_media.c if_vlan.c

Log Message:
Hold KERNEL_LOCK on if_ioctl selectively based on IFEF_MPSAFE

If IFEF_MPSAFE is set, hold the lock and otherwise don't hold.

This change requires additions of KERNEL_LOCK to subsequence functions from
if_ioctl such as ifmedia_ioctl and ifioctl_common to protect non-MP-safe
components.

Proposed on tech-kern@ and tech-net@
