* ieee802154/nl-mac.c: make some MLME operations optionalWerner Almesberger2013-04-08
| | | | | | | | | | | | | | | | | | | | | Check for NULL before calling the following operations from "struct ieee802154_mlme_ops": assoc_req, assoc_resp, disassoc_req, start_req, and scan_req. This fixes a current oops where those functions are called but not implemented. It also updates the documentation to clarify that they are now optional by design. If a call to an unimplemented function is attempted, the kernel returns EOPNOTSUPP via netlink. The following operations are still required: get_phy, get_pan_id, get_short_addr, and get_dsn. Note that the places where this patch changes the initialization of "ret" should not affect the rest of the code since "ret" was always set (again) before returning its value.

* 6lowpan: handle dev_queue_xmit() error code properlyAlan Ott2013-04-07
| | | | | | | | | | | dev_queue_xmit() will return a positive value if the packet could not be queued, often because the real network device (in our case the mac802154 wpan device) has its queue stopped. lowpan_xmit() should handle the positive return code (for the debug statement) and return that value to the higher layer so the higher layer will retry sending the packet.

* 6lowpan: fix first fragment (FRAG1) handlingTony Cheneau2013-03-26
| | | | | | | | | | | | | | | | The first fragment, FRAG1, must contain some payload according to the specs. However, as it is currently written, the first fragment will remain empty and only contain the 6lowpan headers. This patch also extracts the transport layer information from the first fragment. This information is used later on when uncompressing UDP header. Thanks to Wolf-Bastian Pöttner for noticing that the offset value was not properly initialized.

* hlist: drop the node parameter from iteratorsSasha Levin2013-02-27

I'm not quite sure. Not only they don't really need it, it also prevents the iterator from looking exactly like the list iterator, which is unfortunate. Besides the semantic patch, there was some manual work required: - Fix up the actual hlist iterators in linux/list.h - Fix up the declaration of other iterators based on the hlist ones. - A very small amount of places were using the 'node' parameter, this was modified to use 'obj->member' instead. - Coccinelle didn't handle the hlist_for_each_entry_safe iterator properly, so those had to be fixed up manually.

In 'net' we added a bug fix to make iwlwifi report a more accurate skb->truesize but this conflicted with RX path changes that happened meanwhile in net-next. In e1000e a conflict arose in the validation code for settings of adapter->itr. 'net-next' had more sophisticated logic so that logic was used. Signed-off-by: David S. Miller <davem@davemloft.net>
