This is the EAPoL over nl80211 patchset from Denis Kenzior, minus some
infrastructure patches I'd split out and applied earlier. Denis described
it as follows:
This patchset adds support for running 802.11 authentication mechanisms (e.g.
802.1X, 4-Way Handshake, etc) over NL80211 instead of putting them onto the
network device. This has the advantage of fixing several long-standing race
conditions that result from userspace operating on multiple transports in order
to manage a 802.11 connection (e.g. NL80211 and wireless netdev, wlan0, etc).
For example, userspace would sometimes see 4-Way handshake packets before
NL80211 signaled that the connection has been established. Leading to ugly
hacks or having the STA wait for retransmissions from the AP.
This also provides a way to mitigate a particularly nasty race condition where
the encryption key could be set prior to the 4-way handshake packet 4/4 being
sent. This would result in the packet being sent encrypted and discarded by
the peer. The mitigation strategy for this race is for userspace to explicitly
tell the kernel that a particular EAPoL packet should not be encrypted.
To make this possible this patchset introduces a new NL80211 command and several
new attributes. A userspace that is capable of processing EAPoL packets over
NL80211 includes a new NL80211_ATTR_CONTROL_PORT_OVER_NL80211 attribute in its
NL80211_CMD_ASSOCIATE or NL80211_CMD_CONNECT requests being sent to the kernel.
The previously added NL80211_ATTR_SOCKET_OWNER attribute must also be included.
The latter is used by the kernel to send NL80211_CMD_CONTROL_PORT_FRAME
notifications back to userspace via a netlink unicast. If the
NL80211_ATTR_CONTROL_PORT_OVER_NL80211 attribute is not specified, then legacy
behavior is kept and control port packets continue to flow over the network
interface.
If control port over nl80211 transport is requested, then control port packets
are intercepted just prior to being handed to the network device and sent over
netlink via the NL80211_CMD_CONTROL_PORT_FRAME notification.
NL80211_ATTR_CONTROL_PORT_ETHERTYPE and NL80211_ATTR_MAC are included to
specify the control port frame protocol and source address respectively. If
the control port frame was received unencrypted then
NL80211_ATTR_CONTROL_PORT_NO_ENCRYPT flag is also included. NL80211_ATTR_FRAME
attribute contains the raw control port frame with all transport layer headers
stripped (e.g. this would be the raw EAPoL frame).
Userspace can reply to control port frames either via legacy methods (by sending
frames to the network device) or via NL80211_CMD_CONTROL_PORT_FRAME request.
Userspace would included NL80211_ATTR_FRAME with the raw control port frame as
well as NL80211_Attr_MAC and NL80211_ATTR_CONTROL_PORT_ETHERTYPE attributes to
specify the destination address and protocol respectively. This allows
Pre-Authentication (protocol 0x88c7) frames to be sent via this mechanism as
well. Finally, NL80211_ATTR_CONTROL_PORT_NO_ENCRYPT flag can be included to
tell the driver to send the frame unencrypted, e.g. for 4-Way handshake 4/4
frames.
The proposed patchset has been tested in a mac80211_hwsim based environment with
hostapd and iwd.

If userspace requested control port frames to go over 80211, then do so.
The control packets are intercepted just prior to delivery of the packet
to the underlying network device.
Pre-authentication type frames (protocol: 0x88c7) are also forwarded
over nl80211.

This commit implements the TX side of NL80211_CMD_CONTROL_PORT_FRAME.
Userspace provides the raw EAPoL frame using NL80211_ATTR_FRAME.
Userspace should also provide the destination address and the protocol
type to use when sending the frame. This is used to implement TX of
Pre-authentication frames. If CONTROL_PORT_ETHERTYPE_NO_ENCRYPT is
specified, then the driver will be asked not to encrypt the outgoing
frame.
A new EXT_FEATURE flag is introduced so that nl80211 code can check
whether a given wiphy has capability to pass EAPoL frames over nl80211.

This commit also adds cfg80211_rx_control_port function. This is used
to generate a CMD_CONTROL_PORT_FRAME event out to userspace. The
conn_owner_nlportid is used as the unicast destination. This means that
userspace must specify NL80211_ATTR_SOCKET_OWNER flag if control port
over nl80211 routing is requested in NL80211_CMD_CONNECT,
NL80211_CMD_ASSOCIATE, NL80211_CMD_START_AP or IBSS/mesh join.

Rik reports that he sees an increase in CPU use in one benchmark
due to commit 612f1a22f067 "cpuidle: poll_state: Add time limit to
poll_idle()" that caused poll_idle() to call local_clock() in every
iteration of the loop. Utilization increase generally means more
non-idle time with respect to total CPU time (on the average) which
implies reduced CPU frequency.
Doug reports that limiting the rate of local_clock() invocations
in there causes much less power to be drawn during a CPU-intensive
parallel workload (with idle states 1 and 2 disabled to enforce more
state 0 residency).
These two reports together suggest that executing local_clock() on
multiple CPUs in parallel at a high rate may cause chips to get hot
and trigger thermal/power limits on them to kick in, so reduce the
rate of local_clock() invocations in poll_idle() to avoid that issue.
Fixes: 612f1a22f067 "cpuidle: poll_state: Add time limit to poll_idle()"

Add a new attribute group called "s2idle" under the sysfs directory
of each cpuidle state that supports the ->enter_s2idle callback
and put two new attributes, "usage" and "time", into that group to
represent the number of times the given state was requested for
suspend-to-idle and the total time spent in suspend-to-idle after
requesting that state, respectively.
That will allow diagnostic information related to suspend-to-idle
to be collected without enabling advanced debug features and
analyzing dmesg output.

If poll_idle() is allowed to spin until need_resched() returns 'true',
it may actually spin for a much longer time than expected by the idle
governor, since set_tsk_need_resched() is not always called by the
timer interrupt handler. If that happens, the CPU may spend much
more time than anticipated in the "polling" state.
To prevent that from happening, limit the time of the spinning loop
in poll_idle().

Most MMIO GIC register accesses use a 1-hot bit scheme that
avoids requiring any form of locking. This isn't true for the
GICD_ICFGRn registers, which require a RMW sequence.
Unfortunately, we seem to be missing a lock for these particular
accesses, which could result in a race condition if changing the
trigger type on any two interrupts within the same set of 16
interrupts (and thus controlled by the same CFGR register).
Introduce a private lock in the GIC common comde for this
particular case, making it cover both GIC implementations
in one go.

Traditionally, PORTSC should be set before initializing ULPI phys. But
setting PORTSC before powering on the phy results in a kernel freeze
on imx53 based GE PPD. As a workaround this initializes the phy early
in the imx platform code and disables phy power management from the
core.
