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> --- drivers/message/i2o/memory.c | 3 +-- 1 file changed, 1 insertion(+), 2 deletions(-) diff -u -p a/drivers/message/i2o/memory.c b/drivers/message/i2o/memory.c --- a/drivers/message/i2o/memory.c +++ b/drivers/message/i2o/memory.c @@ -270,10 +270,9 @@ EXPORT_SYMBOL_GPL(i2o_dma_realloc); int i2o_pool_alloc(struct i2o_pool *pool, const char *name, size_t size, int min_nr) { - pool->name = kmalloc(strlen(name) + 1, GFP_KERNEL); + pool->name = kstrdup(name, GFP_KERNEL); if (!pool->name) goto exit; - strcpy(pool->name, name); pool->slab = kmem_cache_create(pool->name, size, 0, SLAB_HWCACHE_ALIGN, NULL); -- 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/ |
