Subject: [20/30] [SCSI] megaraid_sas: remove sysfs poll_mode_io world writeable permissions
Date: Wed, 20 Jan 2010 20:15:41 -0800 [thread overview]
Message-ID: <20100121041835.078046215@mini.kroah.org> (raw)
In-Reply-To: <20100121041852.GA9656@kroah.com>
2.6.32-stable review patch. If anyone has any objections, please let us know.
------------------
From: Bryn M. Reeves <bmr@redhat.com>
commit bb7d3f24c71e528989501617651b669fbed798cb upstream.
/sys/bus/pci/drivers/megaraid_sas/poll_mode_io defaults to being
world-writable, which seems bad (letting any user affect kernel driver
behavior).
This turns off group and user write permissions, so that on typical
production systems only root can write to it.
