From: Nikanth Karthikesan <[email protected]> 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: Nikanth Karthikesan <[email protected]> Cc: [email protected] Signed-off-by: Alasdair G Kergon <[email protected]> drivers/md/dm-stripe.c | 2 +- 1 files changed, 1 insertions(+), 1 deletions(-) --- http://git.linuxtv.org/v4l-dvb.git?a=commitdiff;h=781248c1b50c776a9ef4be1130f84ced1cba42fe diff --git a/drivers/md/dm-stripe.c b/drivers/md/dm-stripe.c index e0efc1a..bd58703 100644 --- a/drivers/md/dm-stripe.c +++ b/drivers/md/dm-stripe.c @@ -110,7 +110,7 @@ static int stripe_ctr(struct dm_target *ti, unsigned int argc, char **argv) } stripes = simple_strtoul(argv[0], &end, 10); - if (*end) { + if (!stripes || *end) { ti->error = "Invalid stripe count"; return -EINVAL; } _______________________________________________ linuxtv-commits mailing list [email protected] http://www.linuxtv.org/cgi-bin/mailman/listinfo/linuxtv-commits
