This patch series adds rx control port support over nl80211. Control
port
over nl80211 delivers all EAPOL and PREAUTH frames to userspace. This
conflicts
with the current hostapd handling of pre-auth frames. Therefore, this
feature
gets disabled for hostapd. Furthermore a pending kernel patch is
necessary to
forward pre-auth frames from userspace (otherwise handled by Linux
bridge code).
The corresponding Linux patches for pre-auth support for hostapd are:
- nl80211: add src and dst mac attributes
- nl80211: use src and dst addr attribute for control port tx/rx
These patches are now squashed into one patch and are still pending,
but they are not needed
for the current patch series to work, as hostapd support for rx over
control port is still disabled
in this patch series.
Furthermore another kernel patch is needed, in order to avoid a
deadlock:
- cfg80211: fix deadlocks in autodisconnect work
Please note, that the patch above is now included in the relevant
stable and lts kernels 4.9.98 and 5.4.14 as well as 5.5-rc7.
Therefore, no deadlock should happen when running a recent kernel and
the hwsim tests. The deadlock happened in the
ap_bss_add_reuse_existing test.
* not 4.9.98 but 4.19.98
This patch enables wpa_supplicant to use control port rx over nl80211
for both
EAPOL and PREAUTH frames. wpa_supplicant connects noticeably faster
in my tests
with this patch series applied.
Markus Theil (7):
nl80211: rename nl_connect to nl_connect_and_ctrl
nl80211: tie connect_or_ctrl handle to bss init/destroy
nl80211: add method for sending messages with connection owner
attributes set
nl80211: add helper method for control port usage
nl80211: use and/or set socker owner where necessary
nl80211: disable control port for AP mode
nl80211: correctly handle deauth from scan with ctrl port rx
