025dceb0fa bpf: powerpc64: optimize JIT passes for bpf function calls
Once the JITed images for each function in a multi-function program
are generated after the first three JIT passes, we only need to fix
the target address for the branch instruction corresponding to each
bpf-to-bpf function call.

This introduces the following optimizations for reducing the work
done by the JIT compiler when handling multi-function programs:

  [1] Instead of doing two extra passes to fix the bpf function calls,
      do just one as that would be sufficient.

  [2] During the extra pass, only overwrite the instruction sequences
      for the bpf-to-bpf function calls as everything else would still
      remain exactly the same. This also reduces the number of writes
      to the JITed image.

  [3] Do not regenerate the prologue and the epilogue during the extra
      pass as that would be redundant.

iproute2 commands to reproduce the setup:

ip link add green type vrf table 1
ip link set green up
ip link add eth0.2030 link eth0 type vlan id 2030
ip link set eth0.2030 master green
ip addr add 10.0.0.1/24 dev eth0.2030
ip link set eth0.2030 up

ip link add blue type vrf table 2
ip link set blue up
ip link add br-blue type bridge
ip link set br-blue master blue
ip link set br-blue up
ip link add vxlan-blue type vxlan id 2 local 10.0.0.1 dev eth0.2030 \
 port 4789
ip link set vxlan-blue master br-blue
ip link set vxlan-blue up
ip link set tap-blue master br-blue
ip link set tap-blue up

ip link add red type vrf table 3
ip link set red up
ip link add br-red type bridge
ip link set br-red master red
ip link set br-red up
ip link add vxlan-red type vxlan id 3 local 10.0.0.1 dev eth0.2030 \
 port 4789
ip link set vxlan-red master br-red
ip link set vxlan-red up
ip link set tap-red master br-red
ip link set tap-red up

We faced some issue in the datapath, here are the details:

* Egress traffic:
The vxlan packets are sent directly to the default VRF because it's where the
socket is bound, therefore the traffic has a default route via eth0. the
workaround is to force this traffic to VRF green with ip rules.

* Ingress traffic:
When receiving the traffic on eth0.2030 the vxlan socket is unreachable from
VRF green. The workaround is to enable *udp_l3mdev_accept* sysctl, but
this breaks isolation between overlay and underlay: packets sent from
blue or red by e.g. a guest VM will be accepted by the socket, allowing
injection of VXLAN packets from the overlay.

This patch series fixes the issues describe above by allowing VXLAN socket to be
bound to a specific VRF device therefore looking up in the correct table.

03f1c26b1c test/net: Add script for VXLAN underlay in a VRF
This script tests the support of a VXLAN underlay in a non-default VRF.

It does so by simulating two hypervisors and two VMs, an extended L2
between the VMs with the hypervisors as VTEPs with the underlay in a
VRF, and finally by pinging the two VMs.

It also tests that moving the underlay from a VRF to another works when
down/up the VXLAN interface.

aab8cc3630 vxlan: add support for underlay in non-default VRF
Creating a VXLAN device with is underlay in the non-default VRF makes
egress route lookup fail or incorrect since it will resolve in the
default VRF, and ingress fail because the socket listens in the default
VRF.

This patch binds the underlying UDP tunnel socket to the l3mdev of the
lower device of the VXLAN device. This will listen in the proper VRF and
output traffic from said l3mdev, matching l3mdev routing rules and
looking up the correct routing table.

When the VXLAN device does not have a lower device, or the lower device
is in the default VRF, the socket will not be bound to any interface,
keeping the previous behaviour.

The underlay l3mdev is deduced from the VXLAN lower device
(IFLA_VXLAN_LINK).

6a6d6681ac l3mdev: add function to retreive upper master
Existing functions to retreive the l3mdev of a device did not walk the
master chain to find the upper master. This patch adds a function to
find the l3mdev, even indirect through e.g. a bridge:

+----------+
|          |
| vrf-blue |
|          |
+----+-----+
     |
     |
+----+-----+
|          |
| br-blue  |

     |
     |
+----+-----+
|          |
|   eth0   |
|          |
+----------+

This will properly resolve the l3mdev of eth0 to vrf-blue.

4e4b08e558 tun: remove skb access after netif_receive_skb
In tun.c skb->len was accessed while doing stats accounting after a
call to netif_receive_skb. We can not access skb after this call
because buffers may be dropped.

The fix for this bug would be to store skb->len in local variable and
then use it after netif_receive_skb(). IMO using xdp data size for
accounting bytes will be better because input for tun_xdp_one() is
xdp_buff.

Hence this patch:
- fixes a bug by removing skb access after netif_receive_skb()
- uses xdp data size for accounting bytes

40d9d791c9 arm64: dts: msm8916: Add all CPUs in cooling maps
Each CPU can (and does) participate in cooling down the system but the
DT only captures a handful of them, normally CPU0, in the cooling maps.
Things work by chance currently as under normal circumstances its the
first CPU of each cluster which is used by the operating systems to
probe the cooling devices. But as soon as this CPU ordering changes and
any other CPU is used to bring up the cooling device, we will start
seeing failures.

Also the DT is rather incomplete when we list only one CPU in the
cooling maps, as the hardware doesn't have any such limitations.

Update cooling maps to include all devices affected by individual trip
points.

e3dd762772 Merge branch 'mlxsw-fw_load_policy'
Ido Schimmel says:

====================
mlxsw: Add 'fw_load_policy' devlink parameter

Shalom says:

Currently, drivers do not have the ability to control the firmware
loading policy and they always use their own fixed policy. This prevents
drivers from running the device with a different firmware version for
testing and/or debugging purposes. For example, testing a firmware bug
fix.

For these situations, the new devlink generic parameter,
'fw_load_policy', gives the ability to control this option and allows
drivers to run with a different firmware version than required by the
driver.

Patch #1 adds the new parameter to devlink. The other two patches, #2
and #3, add support for this parameter in the mlxsw driver.

Example:
  # Query the devlink parameters supported by the device
    $ devlink dev param show
    pci/0000:03:00.0:
      name fw_load_policy type generic
        values:
          cmode driverinit value driver

  # Flash new firmware using ethtool
    $ ethtool -f swp1 mellanox/mlxsw_spectrum-13.1703.4.mfa2

  # Toggle parameter
    $ devlink dev param set pci/0000:03:00.0 name fw_load_policy value flash cmode driverinit

  # devlink reset
    $ devlink dev reload pci/0000:03:00.0

  # Query firmware version to show changes took affect

064501c5b6 mlxsw: spectrum: Load firmware version based on devlink parameter
Load firmware version based on 'fw_load_policy' devlink parameter. The
driver supports these two options:
    * DEVLINK_PARAM_FW_LOAD_POLICY_VALUE_DRIVER (0)
      Default, load firmware version preferred by the driver
    * DEVLINK_PARAM_FW_LOAD_POLICY_VALUE_FLASH (1)
      Load firmware currently stored in flash

The second option, 'flash', allow the device to run with different firmware
version than preferred by the driver for testing and/or debugging purposes.
For example, testing a firmware bug fix.

846e980a87 devlink: Add 'fw_load_policy' generic parameter
Many drivers load the device's firmware image during the initialization
flow either from the flash or from the disk. Currently this option is not
controlled by the user and the driver decides from where to load the
firmware image.

'fw_load_policy' gives the ability to control this option which allows the
user to choose between different loading policies supported by the driver.

This parameter can be useful while testing and/or debugging the device. For
example, testing a firmware bug fix.

It's not the same as in 7fe0ee09 patch described.
As 8139cp uses shared irq mode, other device irq will trigger
cp_interrupt to execute.

cp_change_mtu
 -> cp_close
 -> cp_open

In cp_close routine  just before free_irq(), some interrupt may occur.
In my environment, cp_interrupt exectutes and IntrStatus is 0x4,
exactly TxOk. That will cause cp_tx to wake device queue.

As device queue is started, cp_start_xmit and cp_open will run at same
time which will cause kernel BUG.

For example:
[#] for tx descriptor

At start:

[#][#][#]
num_queued=3

After cp_init_hw->cp_start_hw->netdev_reset_queue:

[#][#][#]
num_queued=0

When 8139cp starts to work then cp_tx will check
num_queued mismatchs the complete_bytes.

The patch will check IntrMask before check IntrStatus in cp_interrupt.
When 8139cp interrupt is disabled, just return.

==================================================================

The trace happens because get_hw_stats() assumes there is room in the
memory allocated in init_cntrs() to accommodate the driver counters.
Unfortunately, that routine only allocated space for the device
counters.

Fix by insuring the allocation has room for the additional driver
counters.

90b2620e6a IB/hfi1: Fix a latency issue for small messages
A recent performance enhancement introduced a latency issue in the
HFI message path.  The new algorithm removed a forced call send for
PIO messages and added a forced schedule event for messages larger
than the MTU.

For PIO, the schedule path can introduce thrashing that can
significantly impact the throughput for small messages.

If a message size is within the PIO threshold, always take the send
path.

The OLPC XO-1.75 device tree root is compatible with "mrvl,mmp2" only.

The "mrvl,mmp2-brownstone" string is safe to remove: the Brownstone
device tree contains the "mrvl,mmp2" compatible string too.

f3b2f758ec ARM: dts: realview: Fix some more duplicate regulator nodes
There's a bug in dtc in checking for duplicate node names when there's
another section (e.g. "/ { };"). In this case, skeleton.dtsi provides
another section. Upon removal of skeleton.dtsi, the dtb fails to build
due to a duplicate node 'fixedregulator@0'. As both nodes were pretty
much the same 3.3V fixed regulator, it hasn't really mattered. Fix this
by renaming the nodes to something unique. In the process, drop the
unit-address which shouldn't be present wtihout reg property.

76f4e2c3b6 ARM: mmp/mmp2: fix cpu_is_mmp2() on mmp2-dt
cpu_is_mmp2() was equivalent to cpu_is_pj4(), wouldn't be correct for
multiplatform kernels. Fix it by also considering mmp_chip_id, as is
done for cpu_is_pxa168() and cpu_is_pxa910() above.

Moreover, it is only available with CONFIG_CPU_MMP2 and thus doesn't work
on DT-based MMP2 machines. Enable it on CONFIG_MACH_MMP2_DT too.

Note: CONFIG_CPU_MMP2 is only used for machines that use board files
instead of DT. It should perhaps be renamed. I'm not doing it now, because
I don't have a better idea.

90b1023f68 bpf: fix documentation for eBPF helpers
The missing indentation on the "Return" sections for bpf_map_pop_elem()
and bpf_map_peek_elem() helpers break RST and man pages generation. This
patch fixes them, and moves the description of those two helpers towards
the end of the list (even though they are somehow related to the three
first helpers for maps, the man page explicitly states that the helpers
are sorted in chronological order).

While at it, bring other minor formatting edits for eBPF helpers
documentation: mostly blank lines removal, RST formatting, or other
small nits for consistency.

e3da08d057 bpf: allow BPF read access to qdisc pkt_len
The pkt_len field in qdisc_skb_cb stores the skb length as it will
appear on the wire after segmentation. For byte accounting, this value
is more accurate than skb->len. It is computed on entry to the TC
layer, so only valid there.

Allow read access to this field from BPF tc classifier and action
programs. The implementation is analogous to tc_classid, aside from
restricting to read access.

To distinguish it from skb->len and self-describe export as wire_len.

Changes v1->v2
  - Rename pkt_len to wire_len

The whole libbpf is licensed as (LGPL-2.1 OR BSD-2-Clause). I missed it
while adding README.rst. Fix it and use same license as all other files
in libbpf do. Since I'm the only author of README.rst so far, no others'
permissions should be needed.

Fixes: 76d1b894c5 ("libbpf: Document API and ABI conventions")

9b90dc85c7 media: seco-cec: add missing header file to fix build
Fix build errors due to missing <linux/module.h> header file.
The header file is inserted first because module-related errors
begin showing up in <linux/acpi.h> (when CONFIG_ACPI is not set).

Sample of build errors:
