wilc1000: Make SPI transfers work at 48MHz
For CMD_SINGLE_READ and CMD_INTERNAL_READ, WILC may insert one or more
zero bytes between the command response and the DATA Start tag (0xf3).
This behavior appears to be undocumented in "ATWILC1000 USER GUIDE"
(https://tinyurl.com/4hhshdts) but we have observed 1-4 zero bytes
when the SPI bus operates at 48MHz and none when it operates at 1MHz.
This code is derived from the equivalent code of the wilc driver in
the linux-at91 repository.

mwifiex: don't print SSID to logs
There are a few reasons not to dump SSIDs as-is in kernel logs:
1) they're not guaranteed to be any particular text encoding (UTF-8,
ASCII, ...) in general
2) it's somewhat redundant; the BSSID should be enough to uniquely
identify the AP/STA to which we're connecting
3) BSSIDs have an easily-recognized format, whereas SSIDs do not (they
are free-form)
4) other common drivers (e.g., everything based on mac80211) get along
just fine by only including BSSIDs when logging state transitions
Additional notes on reason #3: this is important for the
privacy-conscious, especially when providing tools that convey
kernel logs on behalf of a user -- e.g., when reporting bugs. So for
example, it's easy to automatically filter logs for MAC addresses, but
it's much harder to filter SSIDs out of unstructured text.

Add a new way to provide the MAC address: via device tree. Besides the

the commit
1ddc3229ad3c ("skbuff: remove some unnecessary operation

one already fixed by commit
53475c5dd856 ("net: fix use-after-free when
UDP GRO with shared fraglist").
If the GSO skb goes though skb_clone() and pskb_expand_head() before
entering skb_segment_list(), the latter will unshare the frag_list
skbs and will release the old list. With the reverted commit in place,
when skb_segment_list() completes, skb->next points to the just
released list, and later on the kernel will hit UaF.
Note that since commit
e0e3070a9bc9 ("udp: properly complete L4 GRO
over UDP tunnel packet") the critical scenario can be reproduced also
receiving UDP over vxlan traffic with:
NIC (NETIF_F_GRO_FRAGLIST enabled) -> vxlan -> UDP sink
Attaching a packet socket to the NIC will cause skb_clone() and the
tunnel decapsulation will call pskb_expand_head().

metadata to indicate source vport. Metadata tagging is not always
needed. Metadata insertion is needed for multi-port RoCE, failover

metadata enablement is not needed.
Metadata insertion slows down the packet processing rate of the E-switch

iwlwifi: pcie: make cfg vs. trans_cfg more robust
If we (for example) have a trans_cfg entry in the PCI IDs table,
but then don't find a full cfg entry for it in the info table,
we fall through to the code that treats the PCI ID table entry
as a full cfg entry. This obviously causes crashes later, e.g.
when trying to build the firmware name string.
Avoid such crashes by using the low bit of the pointer as a tag
for trans_cfg entries (automatically using a macro that checks
the type when assigning) and then checking that before trying to
use the data as a full entry - if it's just a partial entry at
that point, fail.
Since we're adding some macro magic, also check that the type is
in fact either struct iwl_cfg_trans_params or struct iwl_cfg,

iwlwifi: pcie: clear only FH bits handle in the interrupt
For simplicity we assume that msix has 2 IRQ lines one used for rx data
called msix_non_share, and another used for one bit flags messages
(alive, hw error, sw error, rx data flag) called msix_share.
Every time the FW has data to send it puts it on the RX queue and HW
turns on the flags in msix_share (inta_fw) indicating about rx data,
and HW sends an interrupt a bit later to the msix_non_share _unless_
the msix_shared RX data bit was cleared.
Currently in the code every time we get an msix_shared we clear all bits
including rx data queue bits.
So we can have a race
----------------------------------------------------
DRIVER | HW | FW
----------------------------------------------------
- send host cmd to FW | |
| | - handle message
| | and put a response
| | on the RX queue
| - RX flag on |
| | - send alive msix
| - alive flag on |
| - interrupt |
| msix_share driver |
- handle msix_shared | |
and clear all flags | |
bits | |
| - don't send an |
| interrupt on |
| msix_non_shared |
| (driver cleared) |
- driver timeout on | |
waiting for host cmd | |
respond | |
| |
----------------------------------------------------
The change is to clear only the msi_shared flags that are handled in
the msix_shared flow, which will cause the hardware to send an interrupt
on the msix_non_share line as well, when it has data.

During the handling of CAN bus errors, a CAN error SKB is allocated
using alloc_can_err_skb(). Even if the allocation of the SKB fails,
the function continues in order to do the stats handling.
All access to the can_frame pointer (cf) should be guarded by an if
statement:
if (cf)
However, the increment of the rx_bytes stats:
netdev->stats.rx_bytes += cf->can_dlc;
dereferences the cf pointer and was not guarded by an if condition
leading to a NULL pointer dereference if the can_err_skb() function
failed.
Replacing the cf->can_dlc by the macro CAN_ERR_DLC (which is the
length of any CAN error frames) solves this NULL pointer dereference.

dpaa2-switch: add tc hardware offload on ingress traffic
This patch set adds tc hardware offload on ingress traffic in
dpaa2-switch. The cls flower and matchall classifiers are supported
using the same ACL infrastructure supported by the dpaa2-switch.
The first patch creates a new structure to hold all the necessary
information related to an ACL table. This structure is used in the next
patches to create a link between each switch port and the table used.
Multiple ports can share the same ACL table when they also share the
ingress tc block. Also, some small changes in the priority of the
default STP trap is done in the second patch.
The support for cls flower is added in the 3rd patch, while the 4th
one builds on top of the infrastructure put in place and adds cls
matchall support.
The following flow keys are supported:
- Ethernet: dst_mac/src_mac
- IPv4: dst_ip/src_ip/ip_proto/tos
- VLAN: vlan_id/vlan_prio/vlan_tpid/vlan_dei
- L4: dst_port/src_port
Each filter can support only one action from the following list:
- drop
- mirred egress redirect
- trap
With the last patch, we reuse the dpaa2_switch_acl_entry_add() function
added previously instead of open-coding the install of a new ACL entry
into the table.

As per flow actions, the following are supported:
- drop
- mirred egress redirect
- trap
Each ACL entry (filter) can be setup with only one of the listed
actions.
A sorted single linked list is used to keep the ACL entries by their
order of priority. When adding a new filter, this enables us to quickly
ascertain if the new entry has the highest priority of the entire block
or if we should make some space in the ACL table by increasing the
priority of the filters already in the table.

dpaa2-switch: install default STP trap rule with the highest priority
Change the default ACL trap rule for STP frames to have the highest
priority.
In the same ACL table will reside both default rules added by the driver
for its internal use as well as rules added with tc flower. In this
case, the default rules such as the STP one that we already have should
have the highest priority.
Also, remove the check for a full ACL table since we already know that
it's sized so that we don't hit this case. The last thing changes is
that default trap filters will not be counted in the acl_tbl's num_rules
variable since their number doesn't change.
