This commit has fix for RX traffic issues when we stress test the driver
with continuous ifconfig up/down under very high traffic conditions.
Reason for the issue is that, in existing liquidio_stop function NAPI is
disabled even before actual FW/HW interface is brought down via
send_rx_ctrl_cmd(lio, 0). Between time frame of NAPI disable and actual
interface down in firmware, firmware continuously enqueues rx traffic to
host. When interrupt happens for new packets, host irq handler fails in
scheduling NAPI as the NAPI is already disabled.
After "ifconfig <iface> up", Host re-enables NAPI but cannot schedule it
until it receives another Rx interrupt. Host never receives Rx interrupt as
it never cleared the Rx interrupt it received during interface down
operation. NIC Rx interrupt gets cleared only when Host processes queue and
clears the queue counts. Above anomaly leads to other issues like packet
overflow in FW/HW queues, backpressure.
Fix:
This commit fixes this issue by disabling NAPI only after informing
firmware to stop queueing packets to host via send_rx_ctrl_cmd(lio, 0).
send_rx_ctrl_cmd is not visible in the patch as it is already there in the
code. The DOWN command also waits for any pending packets to be processed
by NAPI so that the deadlock will not occur.

This adds initial suport for DWMAC5 and implements the Automotive Safety
Package which is available from core version 5.10.
The Automotive Safety Pacakge (also called Safety Features) offers us
with error protection in the core by implementing ECC Protection in
memories, on-chip data path parity protection, FSM parity and timeout
protection and Application/CSR interface timeout protection.
In case of an uncorrectable error we call stmmac_global_err() and
reconfigure the whole core.

It's common practice to store MAC addresses for network interfaces into
nvmem devices. However the code to actually do this in the kernel lacks,
so this patch adds of_get_nvmem_mac_address() for drivers to obtain the
address from an nvmem cell provider.
This is particulary useful on devices where the ethernet interface cannot
be configured by the bootloader, for example because it's in an FPGA.

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.

In preparation for having DSA transition entirely to PHYLINK, we need to pass a
PHY interface type to the mac_link_{up,down} callbacks because we may have to
make decisions on that (e.g: turn on/off RGMII interfaces etc.). We do not pass
an entire phylink_link_state because not all parameters (pause, duplex etc.) are
defined when the link is down, only link and interface are.
Update mvneta accordingly since it currently implements phylink_mac_ops.

There were a number of issues with setting the RX coalescing parameters:
- we would not be preserving values that would have been configured
across close/open calls, instead we would always reset to no timeout
and 1 interrupt per packet, this would also prevent DIM from setting its
default usec/pkts values
- when adaptive RX would be turned on, we woud not be fetching the
default parameters, we would stay with no timeout/1 packet per interrupt
until the estimator kicks in and changes that
- finally disabling adaptive RX coalescing while providing parameters
would not be honored, and we would stay with whatever DIM had previously
determined instead of the user requested parameters

Cotsworks modules fail the checksums - it appears that Cotsworks

field, and reducing the checksum failures to warnings rather than a

During heavy tx traffic, control messages (sent by liquidio driver to NIC
firmware) sometimes do not get processed in a timely manner. Reason is:
the low-level metadata of control messages and that of egress network
packets indicate that they have the same priority.
Fix it by setting a higher priority for control messages through the new
ctrl_qpg field in the oct_txpciq struct. It is the NIC firmware that does
the actual setting of priority by writing to the new ctrl_qpg field; the
host driver treats that value as opaque and just assigns it to pki_ih3->qpg

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.

mlx5-updates-2018-03-27 (Misc updates & SQ recovery)
This series contains Misc updates and cleanups for mlx5e rx path

From Tariq: (RX updates)
- 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.

rtnl_lock() is used everywhere, and contention is very high.
When someone wants to iterate over alive net namespaces,
he/she has no a possibility to do that without exclusive lock.
But the exclusive rtnl_lock() in such places is overkill,
and it just increases the contention. Yes, there is already
for_each_net_rcu() in kernel, but it requires rcu_read_lock(),
and this can't be sleepable. Also, sometimes it may be need
really prevent net_namespace_list growth, so for_each_net_rcu()
is not fit there.
This patch introduces new rw_semaphore, which will be used
instead of rtnl_mutex to protect net_namespace_list. It is
sleepable and allows not-exclusive iterations over net
namespaces list. It allows to stop using rtnl_lock()
in several places (what is made in next patches) and makes
less the time, we keep rtnl_mutex. Here we just add new lock,
while the explanation of we can remove rtnl_lock() there are
in next patches.
Fine grained locks generally are better, then one big lock,
so let's do that with net_namespace_list, while the situation
allows that.

In ca8210_test_int_user_write() a user can request the transfer of a
frame with a length field (command.length) that is longer than the
actual buffer provided (len). In this scenario the driver will copy
the buffer contents into the uninitialised command[] buffer, then
transfer <data.length> bytes over the SPI even though only <len> bytes
had been populated, potentially leaking sensitive kernel memory.
Also the first 6 bytes of the command buffer must be initialised in case
a malformed, short packet is written and the uninitialised bytes are
read in ca8210_test_check_upstream.

For WPA encryption, QCA6174 firmware(version: WLAN.RM.4.4) will unblock
data when M4 was sent successfully. For other encryption which didn't need
4-way handshake firmware will unblock the data when peer authorized. Since
TDLS is 3-way handshake host need send authorize cmd to firmware to unblock
data.

TDLS peer do not need WEP key. Setting WEP key will lead
to TDLS setup failure. Add fix to avoid setting WEP key
for TDLS peer.

In case wcn36xx_smd_rsp_process() is called more than once before
hal_ind_work was dispatched, the messages will end up in hal_ind_queue,
but wcn36xx_ind_smd_work() will only look at the first message in that
list.
Fix this by dequeing the messages from the list in a loop, and only stop
when it's empty.
This issue was found during a review of the driver. In my tests, that
race never actually occured.

wcn36xx_start_tx function retrieves the buffer descriptor from the
channel control queue to start filling tx buffer information. However,
nothing prevents this same buffer to be concurrently accessed in a
concurent tx call, leading to potential buffer coruption and firmware
crash (observed during iperf test). The channel control queue should
only be accessed and updated with the channel lock.
Fix this issue by using a local buffer descriptor which will be copied
in the thread-safe wcn36xx_dxe_tx_frame.
Note that buffer descriptor size is few bytes so the introduced copy
overhead is insignificant. Moreover, this allows to keep the locked
section minimal.

It appears that the WCN36xx firmware doesn't actually respond to
probe requests. Until it's resolved, switch the probe response
responsibility to the 802.11 layer to allow creation of
hidden SSID AP's.

QCA9984/QCA99X0/QCA4019 chipsets have 8 memory regions, dump all of them to the
firmware coredump file. Some of the regions need to be read using ioread() so
add new region types for them.

As QCA9984 needs two region types refactor the code to make it easier add the
new types. No functional changes.
