There is uninit value bug in dgram_sendmsg function in
net/ieee802154/socket.c when the length of valid data pointed by the
msg->msg_name isn't verified.
This length is specified by msg->msg_namelen. Function
ieee802154_addr_from_sa is called by dgram_sendmsg, which use
msg->msg_name as struct sockaddr_ieee802154* and read it, that will
eventually lead to uninit value read. So we should check the length of
msg->msg_name is not less than sizeof(struct sockaddr_ieee802154)
before entering the ieee802154_addr_from_sa.

This patch has been applied to the wpan tree and will be
part of the next pull request to net. Thanks!
Btw, I got a warning from the checkpatch script that your author and SOB
email addresses do not match. Might be a good idea to fix this.
If you are having trouble to send patches through the company mail
server there is always the option to use the gmail address for sending
the mail and an internal From: header in the patch to fix up the author.
