Bug#1095134: udev: please add support for /dev/megaraid_sas_ioctl_node

[Russell Coker]

Package: udev
Version: 257.2-3
Severity: normal

The following are 2 options I tried in /etc/udev/rules.d/99mega.rules:
DEVPATH=="/module/megaraid_sas" RUN+="/usr/local/sbin/mega"
DRIVER=="megaraid_sas" RUN+="/usr/local/sbin/mega"

I don't know which of them is preferred but they both work.  Below is the
script I use to create the device node, the restorecon line is needed for
correct SE Linux labelling and won't cause any harm if restorecon isn't
installed or if SE Linux is disabled.

#!/bin/bash
set -e
test -e /sys/kernel/debug/megaraid_sas
grep -o -P '^\d\d\d(?= megaraid_sas_ioctl)' /proc/devices > /dev/null

[[ -e /dev/megaraid_sas_ioctl_node ]] || mknod /dev/megaraid_sas_ioctl_node c `grep -o -P '^\d\d\d(?= megaraid_sas_ioctl)' /proc/devices` 0
[ -x /sbin/restorecon ] && /sbin/restorecon /dev/megaraid_sas_ioctl_node
