inet: frag: change *_frag_mem_limit functions to take netns_frags as argument

2015-07-27T04:00:14+00:00

Followup patch will call it after inet_frag_queue was freed, so q->net doesn't work anymore (but netf = q->net; free(q); mem_limit(netf) would). Tested-by: Frank Schreuder Signed-off-by: Florian Westphal Signed-off-by: David S. Miller

ieee802154: 6lowpan: set ackreq when needed

2015-06-02T15:09:35+00:00

This patch sets the acknowledge request bit inside the 802.15.4 mac header when frame retries is 0 or above. The other frame retries value which is -1 indicates that the transmitter doesn't care about an acknowledge frame which will be ignored after transmitting if the node sends anyway an ack frame after receiving. This is currently unnecessary traffic if the max frame retries parameter is -1. Signed-off-by: Alexander Aring Reviewed-by: Stefan Schmidt Signed-off-by: Marcel Holtmann

mac802154: remove mib lock

2015-05-23T15:57:08+00:00

This patch removes the mib lock. The new locking mechanism is to protect the mib values with the rtnl lock. Note that this isn't always necessary if we have an interface up the most mib values are readonly (e.g. address settings). With this behaviour we can remove locking in hotpath like frame parsing completely. It depends on context if we need to hold the rtnl lock or not, this makes the callbacks of ieee802154_mlme_ops unnecessary because these callbacks hols always the locks.

mac802154: use atomic ops for sequence incrementation

2015-05-23T15:57:08+00:00

This patch will use atomic operations for sequence number incrementation while MAC header generation. Upper layers like af_802154 or 6LoWPAN could call this function in a parallel context while generating 802.15.4 MAC header before queuing into wpan interfaces transmit queue.

ieee802154: 6lowpan: fix ARPHRD to ARPHRD_6LOWPAN

2015-03-14T16:11:30+00:00

Currently there exists two interface types with ARPHRD_IEEE802154. These are the 802.15.4 interfaces and 802.15.4 6LoWPAN interfaces. This is more a bug because some userspace applications checks on this value like wireshark. This occurs that wireshark will always try to parse a lowpan interface as 802.15.4 frames. With ARPHRD_6LOWPAN wireshark will parse it as IPv6 frames which is correct. Much applications checks on this value to readout the EUI64 mac address which should be the same for ARPHRD_6LOWPAN. BTLE 6LoWPAN and ieee802154 6LoWPAN will share now the same ARPHRD. Signed-off-by: Alexander Aring Signed-off-by: Marcel Holtmann

ieee802154: fix netns settings

2015-02-14T04:19:58+00:00

6LoWPAN currently doesn't supports x-netns and works only in init_net. With this patch, we ensure that: - the wpan interface cannot be moved to another netns; - the 6lowpan interface cannot be moved to another netns; - the wpan interface is in the same netns than the 6lowpan interface; - the 6lowpan interface is in init_net.

ieee802154: 6lowpan: fix Makefile entry

2015-01-08T14:48:06+00:00

Since commit ea81ac2e7050798109356150ea16e71622a5c329 ("ieee802154: create 6lowpan sub-directory") we have a subdirectory for the ieee802154 6lowpan implementation. This commit also moves the Kconfig entry inside of net/ieee802154/6lowpan/ and forgot to rename the Makefile entry from obj-$(CONFIG_IEEE802154_6LOWPAN) to obj-y and handle the obj-$(CONFIG_IEEE802154_6LOWPAN) inside the created 6lowpan directory. This will occur that the ieee802154_6lowpan can't be build. Signed-off-by: Alexander Aring Signed-off-by: Marcel Holtmann

ieee802154: 6lowpan: rename to core

2015-01-08T06:25:59+00:00

This patch renames the 6lowpan_rtnl.c file to core.c. 6lowpan_rtnl.c contains functionality to put all 802.15.4 6LoWPAN functionality together. Signed-off-by: Alexander Aring Signed-off-by: Marcel Holtmann

ieee802154: 6lowpan: move transmit functionality

This patch moves all relevant transmit functionality into a separate tx.c file. We can simple separate this functionality like we did it in mac802154. Signed-off-by: Alexander Aring Signed-off-by: Marcel Holtmann
