Convert a sequence of kmalloc and memcpy to use kasprintf. The argument is checked for being a string by the presence of a previous call to strlen. The semantic patch that performs this transformation is: (http://coccinelle.lip6.fr/) // <smpl> @@ expression a,flag,len; expression arg,e1,e2; statement S; @@ len = strlen(arg) ... when != len = e1 when != arg = e2 a = - \(kmalloc\|kzalloc\)(len+1,flag) + kasprintf(flag,"%s",arg) <... when != a if (a == NULL || ...) S ...> - memcpy(a,arg,len+1); // </smpl> Signed-off-by: Julia Lawall <julia@xxxxxxx> --- fs/jffs2/dir.c | 3 +-- 1 file changed, 1 insertion(+), 2 deletions(-) diff --git a/fs/jffs2/dir.c b/fs/jffs2/dir.c index ed78a3c..8ee5675 100644 --- a/fs/jffs2/dir.c +++ b/fs/jffs2/dir.c @@ -367,7 +367,7 @@ static int jffs2_symlink (struct inode *dir_i, struct dentry *dentry, const char } /* We use f->target field to store the target path. */ - f->target = kmalloc(targetlen + 1, GFP_KERNEL); + f->target = kasprintf(GFP_KERNEL, "%s", target); if (!f->target) { printk(KERN_WARNING "Can't allocate %d bytes of memory\n", targetlen + 1); mutex_unlock(&f->sem); @@ -376,7 +376,6 @@ static int jffs2_symlink (struct inode *dir_i, struct dentry *dentry, const char goto fail; } - memcpy(f->target, target, targetlen + 1); D1(printk(KERN_DEBUG "jffs2_symlink: symlink's target '%s' cached\n", (char *)f->target)); /* No data here.
