2014-11-12ieee820154: add pan_id setting supportAlexander Aring5-0/+62
This patch adds support for setting pan_id via nl802154 framework. Adding a comment because setting 0xffff as pan_id seems to be valid setting. The pan_id 0xffff as source pan is invalid. I am not sure now about this setting but for the current netlink interface this is an invalid setting, so we do the same now. Maybe we need to change that when we have coordinator support and association support. Signed-off-by: Alexander Aring <alex.aring@gmail.com> Signed-off-by: Marcel Holtmann <marcel@holtmann.org>
2014-11-12ieee820154: remove valid page and channel checksAlexander Aring2-16/+1

2014-11-11Bluetooth: 6lowpan: Remove unnecessary RCU callbackJohan Hedberg1-9/+2
When kfree() is all that's needed to free an object protected by RCU there's a kfree_rcu() convenience function that can be used. This patch updates the 6lowpan code to use this, thereby eliminating the need for the separate peer_free() function.

2014-11-11Bluetooth: Fix mgmt connected notificationJohan Hedberg1-1/+7
This patch fixes a regression that was introduced by commit cb77c3ec075a50e9f956f62dc2e4c0394df1d578. In addition to BT_CONFIG, BT_CONNECTED is also a state in which we may get a remote name and need to indicate over mgmt the connection status. This scenario is particularly likely to happen for incoming connections that do not need authentication since there the hci_conn state will reach BT_CONNECTED before the remote name is received.

2014-11-11Bluetooth: Fix sparse warning in amp.cJohan Hedberg1-9/+16
This fixes the following sparse warning: net/bluetooth/amp.c:152:53: warning: Variable length array is used. The warning itself is probably harmless since this kind of usage of shash_desc is present also in other places in the kernel (there's even a convenience macro SHASH_DESC_ON_STACK available for defining such stack variables). However, dynamically allocated versions are also used in several places of the kernel (e.g. kernel/kexec.c and lib/digsig.c) which have the benefit of not exhibiting the sparse warning. Since there are no more sparse warnings in the Bluetooth subsystem after fixing this one it is now easier to spot whenever new ones might get introduced by future patches.

2014-11-09mac802154: protect address changes via ioctlAlexander Aring1-0/+7

2014-11-09ieee802154: fix iface dump with lowpanAlexander Aring1-3/+14
This patch adds a hacked solution for an interface dump with a running lowpan interface. This will crash because lowpan and wpan interface use the same arphdr. To change the arphdr will change the UAPI, this patch checks on mtu which should on lowpan interface always different than IEEE802154_MTU.

2014-11-066lowpan: move skb_free from error paths in decompressionMartin Townsend3-37/+25
Currently we ensure that the skb is freed on every error path in IPHC decompression which makes it easy to introduce skb leaks. By centralising the skb_free into the receive function it makes future decompression routines easier to maintain. It does come at the expense of ensuring that the skb passed into the decompression routine must not be copied.
