wext: fix potential private ioctl memory content leak

2010-10-29T04:04:15Z

commit df6d02300f7c2fbd0fbe626d819c8e5237d72c62 upstream. When a driver doesn't fill the entire buffer, old heap contents may remain, and if it also doesn't update the length properly, this old heap content will be copied back to userspace. It is very unlikely that this happens in any of the drivers using private ioctls since it would show up as junk being reported by iwpriv, but it seems better to be safe here, so use kzalloc.

wext: Send name on events

2008-08-13T09:39:56Z

In the minimal the wireless extensions oughta send at least the name in addition to the ifindex. Signed-off-by: Jamal Hadi Salim Signed-off-by: David S. Miller

netns: Use net_eq() to compare net-namespaces for optimization.

2008-07-20T05:34:43Z

Without CONFIG_NET_NS, namespace is always &init_net. Compiler will be able to omit namespace comparisons with this patch. Signed-off-by: YOSHIFUJI Hideaki Signed-off-by: David S. Miller

wext: Create IW_REQUEST_FLAG_COMPAT and set it as needed.

2008-06-17T01:34:49Z

Now low-level WEXT ioctl handlers can do compat handling when necessary. Signed-off-by: David S. Miller

wext: Dispatch and handle compat ioctls entirely in net/wireless/wext.c

2008-06-17T01:32:46Z

Next we can kill the hacks in fs/compat_ioctl.c and also dispatch compat ioctls down into the driver and 80211 protocol helper layers in order to handle iw_point objects embedded in stream replies which need to be translated. Signed-off-by: David S. Miller

wext: Pull top-level ioctl dispatch logic into helper function.

wext: Pass iwreq pointer down into standard/private handlers.

2008-06-17T01:31:55Z

They have no need to see the object as an ifreq. Signed-off-by: David S. Miller

wext: Parameterize the standard/private handlers.

2008-06-17T01:30:59Z

The WEXT standard and private handlers to use are now arguments to wireless_process_ioctl(). Signed-off-by: David S. Miller

wext: Pull ioctl permission checking out into helper function.
