Date: Wed, 20 Jan 2010 20:15:41 -0800 From: Greg KH <gregkh@...e.de> To: linux-kernel@...r.kernel.org, stable@...nel.org Cc: stable-review@...nel.org, torvalds@...ux-foundation.org, akpm@...ux-foundation.org, alan@...rguk.ukuu.org.uk, "Bryn M. Reeves" <bmr@...hat.com> Subject: [20/30] [SCSI] megaraid_sas: remove sysfs poll_mode_io world writeable permissions 2.6.32-stable review patch. If anyone has any objections, please let us know. ------------------ From: Bryn M. Reeves <bmr@...hat.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. Signed-off-by: Bryn M.
