If a table containing zero as stripe count is passed into stripe_ctr the code attempts to divide by zero. This patch changes DM_TABLE_LOAD to return -EINVAL if the stripe count is zero. We now get the following error messages: device-mapper: table: 253:0: striped: Invalid stripe count device-mapper: ioctl: error adding target to table Signed-off-by: NNikanth Karthikesan <knikanth@suse.de> Cc: stable@kernel.org Signed-off-by: NAlasdair G Kergon <agk@redhat.com>
