nfp: flower: offload phys port MTU change
Trigger a port mod message to request an MTU change on the NIC when any
physical port representor is assigned a new MTU value. The driver waits
10 msec for an ack that the FW has set the MTU. If no ack is received the
request is rejected and an appropriate warning flagged.
Rather than maintain an MTU queue per repr, one is maintained per app.
Because the MTU ndo is protected by the rtnl lock, there can never be
contention here. Portmod messages from the NIC are also protected by
rtnl so we first check if the portmod is an ack and, if so, handle outside
rtnl and the cmsg work queue.
Acks are detected by the marking of a bit in a portmod response. They are
then verfied by checking the port number and MTU value expected by the
app. If the expected MTU is 0 then no acks are currently expected.
Also, ensure that the packet headroom reserved by the flower firmware is
considered when accepting an MTU change on any repr.

net: Broadcom drivers coalescing fixes
Following Tal's review of the adaptive RX/TX coalescing feature added to the
SYSTEMPORT and GENET driver a number of things showed up:
- adaptive TX coalescing is not actually a good idea with the current way
the estimator will program the ring, this results in a higher CPU load, NAPI
on TX already does a reasonably good job at maintaining the interrupt count low
- both SYSTEMPORT and GENET would suffer from the same issues while configuring
coalescing parameters where the values would just not be applied correctly
based on user settings, so we fix that too
Tal, thanks again for your feedback, I would appreciate if you could review that
the new behavior appears to be implemented correctly.
Thanks!
Changes in v2:
- added Tal's reviewed-by to the first patch
- split DIM initialization from coalescing parameters initialization
- avoid duplicating the same code in bcmgenet_set_coalesce() when configuring RX rings
- fixed the condition where default DIM parameters would be applied when
adaptive RX coalescing would be enabled, do this only if it was disabled before

====================
net: Allow FIB notifiers to fail add and replace
I wanted to revisit how resource overload is handled for hardware offload
of FIB entries and rules. At the moment, the in-kernel fib notifier can
tell a driver about a route or rule add, replace, and delete, but the
notifier can not affect the action. Specifically, in the case of mlxsw
if a route or rule add is going to overflow the ASIC resources the only
recourse is to abort hardware offload. Aborting offload is akin to taking
down the switch as the path from data plane to the control plane simply
can not support the traffic bandwidth of the front panel ports. Further,
the current state of FIB notifiers is inconsistent with other resources
where a driver can affect a user request - e.g., enslavement of a port
into a bridge or a VRF.
As a result of the work done over the past 3+ years, I believe we are
at a point where we can bring consistency to the stack and offloads,
and reliably allow the FIB notifiers to fail a request, pushing an error
along with a suitable error message back to the user. Rather than
aborting offload when the switch is out of resources, userspace is simply
prevented from adding more routes and has a clear indication of why.
This set does not resolve the corner case where rules or routes not
supported by the device are installed prior to the driver getting loaded
and registering for FIB notifications. In that case, hardware offload has
not been established and it can refuse to offload anything, sending
errors back to userspace via extack. Since conceptually the driver owns
the netdevices associated with its asic, this corner case mainly applies
to unsupported rules and any races during the bringup phase.
Patch 1 fixes call_fib_notifiers to extract the errno from the encoded
response from handlers.
Patches 2-5 allow the call to call_fib_notifiers to fail the add or
replace of a route or rule.
Patch 6 adds a simple resource controller to netdevsim to illustrate
how a FIB resource controller can limit the number of route entries.
Changes since RFC
- correct return code for call_fib_notifier
- dropped patch 6 exporting devlink symbols
- limited example resource controller to init_net only
- updated Kconfig for netdevsim to use MAY_USE_DEVLINK
- updated cover letter regarding startup case noted by Ido

netdevsim: Add simple FIB resource controller via devlink
Add devlink support to netdevsim and use it to implement a simple,
profile based resource controller. Only one controller is needed
per namespace, so the first netdevsim netdevice in a namespace
registers with devlink. If that device is deleted, the resource
settings are deleted.
The resource controller allows a user to limit the number of IPv4 and
IPv6 FIB entries and FIB rules. The resource paths are:
/IPv4
/IPv4/fib
/IPv4/fib-rules
/IPv6
/IPv6/fib
/IPv6/fib-rules
The IPv4 and IPv6 top level resources are unlimited in size and can not
be changed. From there, the number of FIB entries and FIB rule entries
are unlimited by default. A user can specify a limit for the fib and
fib-rules resources:
$ devlink resource set netdevsim/netdevsim0 path /IPv4/fib size 96
$ devlink resource set netdevsim/netdevsim0 path /IPv4/fib-rules size 16
$ devlink resource set netdevsim/netdevsim0 path /IPv6/fib size 64
$ devlink resource set netdevsim/netdevsim0 path /IPv6/fib-rules size 16
$ devlink dev reload netdevsim/netdevsim0
such that the number of rules or routes is limited (96 ipv4 routes in the
example above):
$ for n in $(seq 1 32); do ip ro add 10.99.$n.0/24 dev eth1; done
Error: netdevsim: Exceeded number of supported fib entries.
$ devlink resource show netdevsim/netdevsim0
netdevsim/netdevsim0:
name IPv4 size unlimited unit entry size_min 0 size_max unlimited size_gran 1 dpipe_tables non
resources:
name fib size 96 occ 96 unit entry size_min 0 size_max unlimited size_gran 1 dpipe_tables
...
With this template in place for resource management, it is fairly trivial
to extend and shows one way to implement a simple counter based resource
controller typical of network profiles.
Currently, devlink only supports initial namespace. Code is in place to
adapt netdevsim to a per namespace controller once the network namespace
issues are resolved.

- Disable Striding RQ when PCI devices, striding RQ limits the use
of CQE compression feature, which is very critical for slow PCI
devices performance, in this change we will prefer CQE compression
over Striding RQ only on specific "slow" PCIe links.
- RX path cleanups
- Private flag to enable/disable striding RQ
From Eran: (TX fast recovery)
- TX timeout logic improvements, fast SQ recovery and TX error reporting
if a HW error occurs while transmitting on a specific SQ, the driver will
ignore such error and will wait for TX timeout to occur and reset all
the rings. Instead, the current series improves the resiliency for such
HW errors by detecting TX completions with errors, which will report them
and perform a fast recover for the specific faulty SQ even before a TX
timeout is detected.

Merge branch 'eapol-over-nl80211' into mac80211-next
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.

mac80211: allow AP_VLAN operation on crypto controlled devices
In the current implementation, mac80211 advertises the support of
AP_VLANs based on the driver's support for AP mode; it also
blocks encrypted AP_VLAN operation on devices advertising
SW_CRYPTO_CONTROL.
The implementation seems weird in it's current form and could be
often confusing, this is because there can be drivers advertising
both SW_CRYPTO_CONTROL and AP mode support (ex: ath10k) in which case
AP_VLAN will still be supported but only in open BSS and not in
secured BSS.
When SW_CRYPTO_CONTROL is enabled, it makes more sense if the decision
to support AP_VLANs is left to the driver. Mac80211 can then allow
AP_VLAN operations depending on the driver support.

ETSI has recently added new requirements that restrict the WMM

following scenarios in order to comply with these new requirements:
1. When using mac80211 default values;
2. When the userspace tries to configure its own values;
3. When associating to an AP which advertises WWM IE.
When associating to an AP, the client uses the values in the

wcn36xx: Fix firmware crash due to corrupted buffer address
wcn36xx_start_tx function retrieves the buffer descriptor from the

crash (observed during iperf test). The channel control queue should

This reverts commit
55884c045d31a29cf69db8332d1064a1b61dd159.
When Ath10k is in AP mode and an unassociated STA sends a VHT action frame
(Operating Mode Notification for the NSS change) periodically to AP this causes
ath10k to call ath10k_station_assoc() which sends WMI_PEER_ASSOC_CMDID during
NSS update. Over the time (with a certain client it can happen within 15 mins
when there are over 500 of these VHT action frames) continuous calls of
WMI_PEER_ASSOC_CMDID cause firmware to assert due to resource exhaust.
To my knowledge setting WMI_PEER_NSS peer param itself enough to handle NSS
updates and no need to call ath10k_station_assoc(). So revert the original
commit from 2014 as it's unclear why the change was really needed.
Now the firmware assert doesn't happen anymore.

ath9k: fix DFS detector synchronization
some userspace programs (e.g. hostapd) need to set the regulatory domain
before selecting the operating channel. Synchronize DFS detector regardless of
the value of ah->curchan, to avoid situations where wireless scan can't be done
on some 5GHz sub-bands, because dfs_region is constantly UNSET.
