ieee802154: Fix EUI-64 station address validation.

2015-05-31T11:40:53+00:00

Refuse to allow setting an EUI-64 group address as an interface
address, as those are not valid station addresses.

ieee802154: Fix generation of random EUI-64 addresses.

2015-05-31T11:40:53+00:00

Currently, ieee802154_random_extended_addr() has a 50% chance of
generating a group (multicast) address, while this function is used
for generating station addresses (which can't be group addresses)
for interfaces that don't have a hardware-provided address.

Also, in case get_random_bytes() generates the EUI-64 address
00:00:00:00:00:00:00:00 (extremely unlikely), which is an invalid
address, ieee802154_random_extended_addr() reacts by changing it
to 01:00:00:00:00:00:00:00, which is an invalid station address as
well, as it is a group address.

This patch changes the address generation procedure to grab eight
random bytes, treat that as an EUI-64, and then clear the Group
address bit and set the Locally Administered bit, which is in
line with how eth_random_addr() generates random EUI-48s.

mac802154: correct max sifs size handling

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

This patch fix the max sifs size correction when the
IEEE802154_HW_TX_OMIT_CKSUM flag is set. With this flag the sk_buff
doesn't contain the CRC, because the transceiver will add the CRC
while transmit.

Also add some defines for the max sifs frame size value and frame check
sequence according to 802.15.4 standard.

This patch corrects the ieee802154_is_valid_psdu_len function that this
function also checks on reserved values 6-8 for validation the psdu

ieee802154: rename and move WPAN_NUM_ defines

2014-11-17T08:49:17+00:00

This patch moves the 802.15.4 constraints WPAN_NUM_ defines into
"net/ieee802154.h" which should contain all necessary 802.15.4 related
information. Also rename these defines to a common name which is
IEEE802154_MAX_CHANNEL and IEEE802154_MAX_PAGE.

mac802154: add interframe spacing time handling

2014-11-13T03:51:58+00:00

This patch adds a new interframe spacing time handling into mac802154
layer. Interframe spacing time is a time period between each transmit.
This patch adds a high resolution timer into mac802154 and starts on
xmit complete with corresponding interframe spacing expire time if
ifs_handling is true. We make it variable because it depends if
interframe spacing time is handled by transceiver or mac802154. At the
timer complete function we wake the netdev queue again. This avoids
new frame transmit in range of interframe spacing time.

For synced driver we add no handling of interframe spacing time. This
is currently a lack of support in all synced xmit drivers. I suppose
it's working because the latency of workqueue which is needed to call
spi_sync.

ieee820154: add short_addr setting support

2014-11-12T04:10:40+00:00

This patch adds support for setting short address via nl802154 framework.
Also added a comment because a 0xffff seems to be valid address that we
don't have a short address. This is a valid setting but we need
more checks in upper layers to don't allow this address as source address.
Also the current netlink interface doesn't allow to set the short_addr
to 0xffff. Same for the 0xfffe short address which describes a not
allocated short address.

ieee820154: add pan_id setting support

2014-11-12T04:10:39+00:00

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.
