From: Julia Lawall <julia@xxxxxxx> The few lines below the kfree of hdr_buf may go to the label err_free which will also free hdr_buf. The most straightforward solution seems to be to just move the kfree of hdr_buf after these gotos. A simplified version of the semantic match that finds this problem is as follows: (http://coccinelle.lip6.fr/) // <smpl> @r@ identifier E; expression E1; iterator I; statement S; @@ *kfree(E); ... when != E = E1 when != I(E,...) S when != &E *kfree(E); // </smpl> Signed-off-by: Julia Lawall <julia@xxxxxxx> --- drivers/scsi/ses.c | 4 ++-- 1 files changed, 2 insertions(+), 2 deletions(-) diff --git a/drivers/scsi/ses.c b/drivers/scsi/ses.c index 55b034b..3c8a024 100644 --- a/drivers/scsi/ses.c +++ b/drivers/scsi/ses.c @@ -591,8 +591,6 @@ static int ses_intf_add(struct device *cdev, ses_dev->page10_len = len; buf = NULL; } - kfree(hdr_buf); - scomp = kzalloc(sizeof(struct ses_component) * components, GFP_KERNEL); if (!scomp) goto err_free; @@ -604,6 +602,8 @@ static int ses_intf_add(struct device *cdev, goto err_free; } + kfree(hdr_buf); + edev->scratch = ses_dev; for (i = 0; i < components; i++) edev->component[i].scratch = scomp + i; -- To unsubscribe from this list: send the line "unsubscribe kernel-janitors" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
