095cb94749 wifi: ath11k: allow missing memory-regions
On SC7280 platforms which are running with TrustZone, it is not
necessary to manually map the memory regions used by the wifi hardware.
However, ath11k will currently fail to load unless both memory regions
are specified.

This breaks wifi on the rb3gen2 which only specifies the firmware memory
region and does not use the CE region.

Adjust the order of operations in ath11k_ahb_fw_resources_init() to
check for the wifi-firmware subnode before attempting to parse the
memory regions.

c9c6a4f1be wifi: ath11k: enable fw_wmi_diag_event hw param for WCN6750
WCN6750 firmware sends the log messages via WMI_DIAG_EVENTID only
when the host driver enables the same via QMI_WLANFW_WLAN_INI_REQ_V01
QMI message. This is further controlled via fw_wmi_diag_event.
Hence set this flag to true for the firmware to send the logs.
These logs are further collected in the user space through
the trace infrastructure.

5094204ff5 wifi: ath11k: Fix double free issue during SRNG deinit
Currently struct ath11k_hal::srng_config pointer is not assigned
to NULL after freeing the memory in ath11k_hal_srng_deinit().
This could lead to double free issue in a scenario where
ath11k_hal_srng_deinit() is invoked back to back.

In the current code, although the chances are very low, the above
said scenario could happen when hardware recovery has failed and
then there is another FW assert where ath11k_hal_srng_deinit() is
invoked once again as part of recovery.

Fix this by assigning the struct ath11k_hal::srng_config pointer
to NULL after freeing the memory.

52db16ec5b wifi: ath10k: fix invalid VHT parameters in supported_vht_mcs_rate_nss2
In supported_vht_mcs_rate_nss2, the rate for MCS9 & VHT20 is defined as
{1560, 1733}, this does not align with firmware's definition and therefore
fails the verification in ath10k_mac_get_rate_flags_vht():

	invalid vht params rate 1730 100kbps nss 2 mcs 9

and:

	invalid vht params rate 1920 100kbps nss 2 mcs 9

Change it to {1730,  1920} to align with firmware to fix the issue.

Since ath10k_hw_params::supports_peer_stats_info is enabled only for
QCA6174, this change does not affect other chips.

Unfiltered DUMP request don't need the dev pointer to be set in the context

7bb50f30c1 Merge branch 'net-fib_rules-add-dscp-selector-support'
Ido Schimmel says:

====================
net: fib_rules: Add DSCP selector support

Currently, the kernel rejects IPv4 FIB rules that try to match on the
upper three DSCP bits:

 # ip -4 rule add tos 0x1c table 100
 # ip -4 rule add tos 0x3c table 100
 Error: Invalid tos.

The reason for that is that historically users of the FIB lookup API
only populated the lower three DSCP bits in the TOS field of the IPv4
flow key ('flowi4_tos'), which fits the TOS definition from the initial
IPv4 specification (RFC 791).

This is not very useful nowadays and instead some users want to be able
to match on the six bits DSCP field, which replaced the TOS and IP
precedence fields over 25 years ago (RFC 2474). In addition, the current
behavior differs between IPv4 and IPv6 which does allow users to match
on the entire DSCP field using the TOS selector.

Recent patchsets made sure that callers of the FIB lookup API now
populate the entire DSCP field in the IPv4 flow key. Therefore, it is
now possible to extend FIB rules to match on DSCP.

This is done by adding a new DSCP attribute which is implemented for
both IPv4 and IPv6 to provide user space programs a consistent behavior
between both address families.

The behavior of the old TOS selector is unchanged and IPv4 FIB rules
using it will only match on the lower three DSCP bits. The kernel will
reject rules that try to use both selectors.

Patch #1 adds the new DSCP attribute but rejects its usage.

Patches #2-#3 implement IPv4 and IPv6 support.

Patch #4 allows user space to use the new attribute.

Patches #5-#6 add selftests.

2cf630034e ipv6: fib_rules: Add DSCP selector support
Implement support for the new DSCP selector that allows IPv6 FIB rules
to match on the entire DSCP field. This is done despite the fact that
the above can be achieved using the existing TOS selector, so that user
space program will be able to work with IPv4 and IPv6 rules in the same
way.

Differentiate between both selectors by adding a new bit in the IPv6 FIB
rule structure that is only set when the 'FRA_DSCP' attribute is
specified by user space. Reject rules that use both selectors.

c951a29f6b net: fib_rules: Add DSCP selector attribute
The FIB rule TOS selector is implemented differently between IPv4 and
IPv6. In IPv4 it is used to match on the three "Type of Services" bits
specified in RFC 791, while in IPv6 is it is used to match on the six
DSCP bits specified in RFC 2474.

Add a new FIB rule attribute to allow matching on DSCP. The attribute
will be used to implement a 'dscp' selector in ip-rule with a consistent
behavior between IPv4 and IPv6.

For now, set the type of the attribute to 'NLA_REJECT' so that user
space will not be able to configure it. This restriction will be lifted
once both IPv4 and IPv6 support the new attribute.

26d7460222 memory-provider: disable building dmabuf mp on !CONFIG_PAGE_POOL
When CONFIG_TRACEPOINTS=y but CONFIG_PAGE_POOL=n, we end up with this
build failure that is reported by the 0-day bot:

ld: vmlinux.o: in function `mp_dmabuf_devmem_alloc_netmems':
>> (.text+0xc37286): undefined reference to `__tracepoint_page_pool_state_hold'
>> ld: (.text+0xc3729a): undefined reference to `__SCT__tp_func_page_pool_state_hold'
>> ld: vmlinux.o:(__jump_table+0x10c48): undefined reference to `__tracepoint_page_pool_state_hold'
>> ld: vmlinux.o:(.static_call_sites+0xb824): undefined reference to `__SCK__tp_func_page_pool_state_hold'

The root cause is that in this configuration, traces are enabled but the
page_pool specific trace_page_pool_state_hold is not registered.

There is no reason to build the dmabuf memory provider when
CONFIG_PAGE_POOL is not present, as it's really a provider to the
page_pool.

In fact the whole NET_DEVMEM is RX path-only at the moment, so we can
make the entire config dependent on the PAGE_POOL.

Note that this may need to be revisited after/while devmem TX is
added,  as devmem TX likely does not need CONFIG_PAGE_POOL. For now this
build fix is sufficient.
