net: renesas: rswitch: Add spin lock protection for irq {un}mask
Add spin lock protection for irq {un}mask registers' control.
After napi_complete_done() and this protection were applied,
a lot of redundant interrupts no longer occur.
For example: when "iperf3 -c <ipaddr> -R" on R-Car S4-8 Spider
Before the patches are applied: about 800,000 times happened
After the patches were applied: about 100,000 times happened

ixgbe: fix timestamp configuration code
The commit in fixes introduced flags to control the status of hardware
configuration while processing packets. At the same time another structure
is used to provide configuration of timestamper to user-space applications.
The way it was coded makes this structures go out of sync easily. The
repro is easy for 82599 chips:
[root@hostname ~]# hwstamp_ctl -i eth0 -r 12 -t 1
current settings:
tx_type 0
rx_filter 0
new settings:
tx_type 1
rx_filter 12
The eth0 device is properly configured to timestamp any PTPv2 events.
[root@hostname ~]# hwstamp_ctl -i eth0 -r 1 -t 1
current settings:
tx_type 1
rx_filter 12
SIOCSHWTSTAMP failed: Numerical result out of range
The requested time stamping mode is not supported by the hardware.
The error is properly returned because HW doesn't support all packets
timestamping. But the adapter->flags is cleared of timestamp flags
even though no HW configuration was done. From that point no RX timestamps
are received by user-space application. But configuration shows good
values:
[root@hostname ~]# hwstamp_ctl -i eth0
current settings:
tx_type 1
rx_filter 12
Fix the issue by applying new flags only when the HW was actually
configured.

The obvious fix is to move the call to macb_set_tx_clk() out of the
protected area. This seems safe as rx and tx are both disabled anyway at
this point.
It is however not entirely clear what the spinlock shall protect. It
could be the read-modify-write access to the NCFGR register, but this
is accessed in macb_set_rx_mode() and macb_set_rxcsum_feature() as well
without holding the spinlock. It could also be the register accesses
done in mog_init_rings() or macb_init_buffers(), but again these
functions are called without holding the spinlock in macb_hresp_error_task().
The locking seems fishy in this driver and it might deserve another look
before this patch is applied.

net:ethernet:adi:adin1110: Fix forwarding offload
Currently, when a new fdb entry is added (with both ports of the
ADIN2111 bridged), the driver configures the MAC filters for the wrong
port, which results in the forwarding being done by the host, and not
actually hardware offloaded.
The ADIN2111 offloads the forwarding by setting filters on the
destination MAC address of incoming frames. Based on these, they may be
routed to the other port. Thus, if a frame has to be forwarded from port
1 to port 2, the required configuration for the ADDR_FILT_UPRn register
should set the APPLY2PORT1 bit (instead of APPLY2PORT2, as it's
currently the case).

net: stmmac: fix handling of zero coalescing tx-usecs
Setting ethtool -C eth0 tx-usecs 0 is supposed to disable the use of the
coalescing timer but currently it gets programmed with zero delay
instead.
Disable the use of the coalescing timer if tx-usecs is zero by
preventing it from being restarted. Note that to keep things simple we
don't start/stop the timer when the coalescing settings are changed, but
just let that happen on the next transmit or timer expiry.

octeontx2-pf: Fix page pool cache index corruption.
The access to page pool `cache' array and the `count' variable
is not locked. Page pool cache access is fine as long as there
is only one consumer per pool.
octeontx2 driver fills in rx buffers from page pool in NAPI context.
If system is stressed and could not allocate buffers, refiiling work
will be delegated to a delayed workqueue. This means that there are
two cosumers to the page pool cache.
Either workqueue or IRQ/NAPI can be run on other CPU. This will lead
to lock less access, hence corruption of cache pool indexes.
To fix this issue, NAPI is rescheduled from workqueue context to refill
rx buffers.

net: enetc: distinguish error from valid pointers in enetc_fixup_clear_rss_rfs()
enetc_psi_create() returns an ERR_PTR() or a valid station interface
pointer, but checking for the non-NULL quality of the return code blurs
that difference away. So if enetc_psi_create() fails, we call
enetc_psi_destroy() when we shouldn't. This will likely result in
crashes, since enetc_psi_create() cleans up everything after itself when
it returns an ERR_PTR().

net: hns3: fix invalid mutex between tc qdisc and dcb ets command issue
We hope that tc qdisc and dcb ets commands can not be used crosswise.
If we want to use any of the commands to configure tc,
We must use the other command to clear the existing configuration.
However, when we configure a single tc with tc qdisc,
we can still configure it with dcb ets.
Because we use mqprio_active as the tag of tc qdisc configuration,
but with dcb ets, we do not check mqprio_active.
This patch fix this issue by check mqprio_active before
executing the dcb ets command. and add dcb_ets_active to
replace HCLGE_FLAG_DCB_ENABLE and HCLGE_FLAG_MQPRIO_ENABLE

net: hns3: fix tx timeout issue
Currently, the driver knocks the ring doorbell before updating
the ring->last_to_use in tx flow. if the hardware transmiting
packet and napi poll scheduling are fast enough, it may get
the old ring->last_to_use in drivers' napi poll.
In this case, the driver will think the tx is not completed, and
return directly without clear the flag __QUEUE_STATE_STACK_XOFF,
which may cause tx timeout.

mlx5/core: E-Switch, Create ACL FT for eswitch manager in switchdev mode
ACL flow table is required in switchdev mode when metadata is enabled, driver creates such table when loading each vport. However, not every vport is loaded in switchdev mode. Such as ECPF if it's the eswitch manager. In this case, ACL flow table is still needed. To make it modularized, create ACL flow table for eswitch manager as default and skip such operations when loading manager vport. Also, there is no need to load the eswitch manager vport in switchdev mode. This means there is no need to load it on regular connect-x HCAs where the PF is the eswitch manager. This will avoid creating duplicate ACL flow table for host PF vport. Fixes: |

net/mlx5e: Clear mirred devices array if the rule is split
In the cited commit, the mirred devices are recorded and checked while
parsing the actions. In order to avoid system crash, the duplicate
action in a single rule is not allowed.
But the rule is actually break down into several FTEs in different
tables, for either mirroring, or the specified types of actions which
use post action infrastructure.
It will reject certain action list by mistake, for example:
actions:enp8s0f0_1,set(ipv4(ttl=63)),enp8s0f0_0,enp8s0f0_1.
Here the rule is split to two FTEs because of pedit action.
To fix this issue, when parsing the rule actions, reset if_count to
clear the mirred devices array if the rule is split to multiple
FTEs, and then the duplicate checking is restarted.

igc: Change IGC_MIN to allow set rx/tx value between 64 and 80
Change the minimum value of RX/TX descriptors to 64 to enable setting the rx/tx value between 64 and 80. All igc devices can use as low as 64 descriptors. This change will unify igc with other drivers. Based on commit |

octeontx2-af: Fix truncation of smq in CN10K NIX AQ enqueue mbox handler
The smq value used in the CN10K NIX AQ instruction enqueue mailbox
handler was truncated to 9-bit value from 10-bit value because of
typecasting the CN10K mbox request structure to the CN9K structure.
Though this hasn't caused any problems when programming the NIX SQ
context to the HW because the context structure is the same size.
However, this causes a problem when accessing the structure parameters.
This patch reads the right smq value for each platform.

gve: fix frag_list chaining
gve_rx_append_frags() is able to build skbs chained with frag_list,
like GRO engine.
Problem is that shinfo->frag_list should only be used
for the head of the chain.
All other links should use skb->next pointer.
Otherwise, built skbs are not valid and can cause crashes.
Equivalent code in GRO (skb_gro_receive()) is:
if (NAPI_GRO_CB(p)->last == p)
skb_shinfo(p)->frag_list = skb;
else
NAPI_GRO_CB(p)->last->next = skb;
NAPI_GRO_CB(p)->last = skb;

v6.6 merge window RDMA pull request
Many small changes across the subystem, some highlights:
- Usual driver cleanups in qedr, siw, erdma, hfi1, mlx4/5, irdma, mthca,
hns, and bnxt_re
- siw now works over tunnel and other netdevs with a MAC address by
removing assumptions about a MAC/GID from the connection manager
- "Doorbell Pacing" for bnxt_re - this is a best effort scheme to allow
userspace to slow down the doorbell rings if the HW gets full
- irdma egress VLAN priority, better QP/WQ sizing
- rxe bug fixes in queue draining and srq resizing
- Support more ethernet speed options in the core layer
- DMABUF support for bnxt_re
- Multi-stage MTT support for erdma to allow much bigger MR registrations
- A irdma fix with a CVE that came in too late to go to -rc, missing
bounds checking for 0 length MRs

sfc: check for zero length in EF10 RX prefix
When EF10 RXDP firmware is operating in cut-through mode, packet length
is not known at the time the RX prefix is generated, so it is left as
zero and RX event merging is inhibited to ensure that the length is
available in the RX event. However, it has been found that in certain
circumstances the RX events for these packets still get merged,
meaning the driver cannot read the length from the RX event, and tries
to use the length from the prefix.
The resulting zero-length SKBs cause crashes in GRO since commit

Pull PCI updates from Bjorn Helgaas:
"Enumeration:
- Add locking to read/modify/write PCIe Capability Register accessors
for Link Control and Root Control
- Use pci_dev_id() when possible instead of manually composing ID
from dev->bus->number and dev->devfn
Resource management:
- Move prototypes for __weak sysfs resource files to linux/pci.h to
fix 'no previous prototype' warnings
- Make more I/O port accesses depend on HAS_IOPORT
- Use devm_platform_get_and_ioremap_resource() instead of open-coding
platform_get_resource() followed by devm_ioremap_resource()
Power management:
- Ensure devices are powered up while accessing VPD
- If device is powered-up, keep it that way while polling for PME
- Only read PCI_PM_CTRL register when available, to avoid reading the
wrong register and corrupting dev->current_state
Virtualization:
- Avoid Secondary Bus Reset on NVIDIA T4 GPUs
Error handling:
- Remove unused pci_disable_pcie_error_reporting()
- Unexport pci_enable_pcie_error_reporting(), used only by aer.c
- Unexport pcie_port_bus_type, used only by PCI core
VGA:
- Simplify and clean up typos in VGA arbiter
Apple PCIe controller driver:
- Initialize pcie->nvecs (number of available MSIs) before use
Broadcom iProc PCIe controller driver:
- Use of_property_read_bool() instead of low-level accessors for
boolean properties
Broadcom STB PCIe controller driver:
- Assert PERST# when probing BCM2711 because some bootloaders don't
do it
Freescale i.MX6 PCIe controller driver:
- Add .host_deinit() callback so we can clean up things like
regulators on probe failure or driver unload
Freescale Layerscape PCIe controller driver:
- Add support for link-down notification so the endpoint driver can
process LINK_DOWN events
- Add suspend/resume support, including manual
PME_Turn_off/PME_TO_Ack handshake
- Save Link Capabilities during probe so they can be restored when
handling a link-up event, since the controller loses the Link Width
and Link Speed values during reset
Intel VMD host bridge driver:
- Fix disable of bridge windows during domain reset; previously we
cleared the base/limit registers, which actually left the windows
enabled
Marvell MVEBU PCIe controller driver:
- Remove unused busn member
Microchip PolarFlare PCIe controller driver:
- Fix interrupt bit definitions so the SEC and DED interrupt handlers
work correctly
- Make driver buildable as a module
- Read FPGA MSI configuration parameters from hardware instead of
hard-coding them
Microsoft Hyper-V host bridge driver:
- To avoid a NULL pointer dereference, skip MSI restore after
hibernate if MSI/MSI-X hasn't been enabled
NVIDIA Tegra194 PCIe controller driver:
- Revert 'PCI: tegra194: Enable support for 256 Byte payload' because
Linux doesn't know how to reduce MPS from to 256 to 128 bytes for
endpoints below a switch (because other devices below the switch
might already be operating), which leads to 'Malformed TLP' errors
Qualcomm PCIe controller driver:
- Add DT and driver support for interconnect bandwidth voting for
'pcie-mem' and 'cpu-pcie' interconnects
- Fix broken SDX65 'compatible' DT property
- Configure controller so MHI bus master clock will be switched off
while in ASPM L1.x states
- Use alignment restriction from EPF core in EPF MHI driver
- Add Endpoint eDMA support
- Add MHI eDMA support
- Add Snapdragon SM8450 support to the EPF MHI driversupport
- Add MHI eDMA support
- Add Snapdragon SM8450 support to the EPF MHI driversupport
- Add MHI eDMA support
- Add Snapdragon SM8450 support to the EPF MHI driversupport
- Add MHI eDMA support
- Add Snapdragon SM8450 support to the EPF MHI driver
- Use iATU for EPF MHI transfers smaller than 4K to avoid eDMA setup
latency
- Add sa8775p DT binding and driver support
Rockchip PCIe controller driver:
- Use 64-bit mask on MSI 64-bit PCI address to avoid zeroing out the
upper 32 bits
SiFive FU740 PCIe controller driver:
- Set the supported number of MSI vectors so we can use all available
MSI interrupts
Synopsys DesignWare PCIe controller driver:
- Add generic dwc suspend/resume APIs (dw_pcie_suspend_noirq() and
dw_pcie_resume_noirq()) to be called by controller driver
suspend/resume ops, and a controller callback to send PME_Turn_Off
MicroSemi Switchtec management driver:
- Add support for PCIe Gen5 devices
Miscellaneous:
- Reorder and compress to reduce size of struct pci_dev
- Fix race in DOE destroy_work_on_stack()
- Add stubs to avoid casts between incompatible function types
- Explicitly include correct DT includes to untangle headers"

Modules changes for v6.6-rc1
Summary of the changes worth highlighting from most interesting to boring below:
* Christoph Hellwig's symbol_get() fix to Nvidia's efforts to circumvent the
protection he put in place in year 2020 to prevent proprietary modules from
using GPL only symbols, and also ensuring proprietary modules which export
symbols grandfather their taint. That was done through year 2020 commit

ethernet: tg3: remove unreachable code
'tp->irq_max' value is either 1 [L16336] or 5 [L16354], as indicated in
tg3_get_invariants(). Therefore, 'i' can't exceed 4 in tg3_init_one()
that makes (i <= 4) always true. Moreover, 'intmbx' value set at the
last iteration is not used later in it's scope.

octeontx2-af: print error message incase of invalid pf mapping
During AF driver initialization, it creates a mapping between pf to cgx,lmac pair. Whenever there is a physical link change, using this mapping driver forwards the message to the associated netdev.
