Hi,
For some time I am playing around with tools like scapy, senf, lorcon etc.
Which allow to receive and construct frames in user-space and send them
with
pcap or raw sockets. I am trying to achieve the injection part with
NL80211_CMD_FRAME. According to the description, only management frames are
supported by this command. Am I right ?
I put some printks into nl80211.c and mlme.c to follow the transmission
part
and to understand where my commands are failing.
I¹ve put my interface into master mode (NL80211_IFTYPE_AP) in order pass
the
checks in cfg80211. When I try to send down a beacon frame or another
management frame I got an error from cfg80211_mlme_mgmt_tx in mlme.c.
rdev_mgmt_tx returns an error code. How can I figure out why my frame is
not
send down on the wiphy ?
By the way, why is CMD_FRAME only restricted to management frames ?
Regards,
Hakan
