Someone can lookup entry with NULL ->owner, thus not pinning enything, and release it later resulting in module refcount underflow. We can keep ->owner and supply it at registration time like ->proc_fops and ->data. But this leaves ->owner as easy-manipulative field (just one C assignment) and somebody will forget to unpin previous/pin current module when switching ->owner. ->proc_fops is declared as "const" which should give some thoughts. ->read_proc/->write_proc were just fixed to not require ->owner for protection. rmmod'ed directories will be empty and return "." and ".." -- no harm. And directories with tricky enough readdir and lookup shouldn't be modular. We definitely don't want such modular code. Removing ->owner will also make PDE smaller. So, let's nuke it. Kudos to Jeff Layton for reminding about this, let's say, oversight. http://bugzilla.kernel.org/show_bug.cgi?id=12454 Signed-off-by: Alexey Dobriyan --- drivers/net/wireless/airo.c | 1 - 1 file changed, 1 deletion(-) (limited to 'drivers/net/wireless/airo.c') diff --git a/drivers/net/wireless/airo.c b/drivers/net/wireless/airo.c index 7e80aba8a14..31b1cc2b778 100644 --- a/drivers/net/wireless/airo.c +++ b/drivers/net/wireless/airo.c @@ -4494,7 +4494,6 @@ static int setup_proc_entry( struct net_device *dev, goto fail; apriv->proc_entry->uid = proc_uid; apriv->proc_entry->gid = proc_gid; - apriv->proc_entry->owner = THIS_MODULE; /* Setup the StatsDelta */ entry = proc_create_data("StatsDelta", -- cgit v1.2.3
