Next: [PATCH 5/10] drivers/message/i2o/memory.c: Use kstrdup
From: Julia Lawall on 14 May 2010 15:40 From: Julia Lawall <julia(a)diku.dk> Use kstrdup when the goal of an allocation is copy a string into the allocated region. The semantic patch that makes this change is as follows: (http://coccinelle.lip6.fr/) // <smpl> @@ expression from,to; expression flag,E1,E2; statement S; @@ - to = kmalloc(strlen(from) + 1,flag); + to = kstrdup(from, flag); ... when != \(from = E1 \| to = E1 \) if (to==NULL || ...) S ... when != \(from = E2 \| to = E2 \) - strcpy(to, from); // </smpl> Signed-off-by: Julia Lawall <julia(a)diku.dk> --- security/selinux/ss/policydb.c | 3 +-- 1 file changed, 1 insertion(+), 2 deletions(-) diff -u -p a/security/selinux/ss/policydb.c b/security/selinux/ss/policydb.c --- a/security/selinux/ss/policydb.c +++ b/security/selinux/ss/policydb.c @@ -156,12 +156,11 @@ static int roles_init(struct policydb *p rc = -EINVAL; goto out_free_role; } - key = kmalloc(strlen(OBJECT_R) + 1, GFP_KERNEL); + key = kstrdup(OBJECT_R, GFP_KERNEL); if (!key) { rc = -ENOMEM; goto out_free_role; } - strcpy(key, OBJECT_R); rc = hashtab_insert(p->p_roles.table, key, role); if (rc) goto out_free_key; -- To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to majordomo(a)vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/ |
