ieee802154: ca8210: fix possible u8 overflow in ca8210_rx_done

2018-12-11T08:33:11+00:00

gcc warning this:

drivers/net/ieee802154/ca8210.c:730:10: warning:
 comparison is always false due to limited range of data type [-Wtype-limits]

'len' is u8 type, we get it from buf[1] adding 2, which can overflow.
This patch change the type of 'len' to unsigned int to avoid this,also fix
the gcc warning.

ieee802154: hwsim: fix off-by-one in parse nested

2018-12-02T10:08:46+00:00

This patch fixes a off-by-one mistake in nla_parse_nested() functions of
mac802154_hwsim driver. I had to enabled stack protector so I was able
to reproduce it.

pull-request: ieee802154-next 2018-10-04

An update from ieee802154 for *net-next*

A very quite cycle in the ieee802154 subsystem. We only have two cleanup
patches for this pull request.
Xue removed the platform_data struct handling from the mcr20a driver and
Alexander cleaned up some left overs in the hwsim driver.

Please pull, or let me know if there are any problems.

ieee802154: hwsim: remove not used ifup list

2018-10-02T15:14:13+00:00

This list is a leftover from fakelb driver which had always a full mesh
topology. Idea was to remember all phy's which are currently used by the
subsystem and deliver everything out. The hwsim driver works differently
each phy has a list of other phy's to deliver frames which allows a
own mesh topology.

ieee802154: mcr20a: Remove struct mcr20a_platform_data

2018-09-28T14:06:14+00:00

The struct mcr20a_platform_data is uesed only in probe function
and it holds only one member. So it is not necessary to reserve it.

Using gpiod family API to handle reset pin.

ieee802154: mcr20a: Replace magic number with constants

2018-09-27T15:22:48+00:00

The combination of defined constants are used to present the
state of IRQ so the magic numbers has been replaced.

This is a simple coding style change which should have no impact on
runtime code execution.

ieee802154: hwsim: using right kind of iteration

2018-08-14T16:58:57+00:00

This patch fixes the error path to unsubscribe all other phy's from
current phy. The actually code using a wrong kind of list iteration may
copied from the case to unsubscribe the current phy from all other
phy's.
