So far the vmtest.sh script, which can be used as a convenient way to
run bpf selftests, has obtained the kernel config safe to use for
testing from the libbpf/libbpf GitHub repository [0].
Given that we now have included this configuration into this very
repository, we can just consume it from here as well, eliminating the
necessity of remote accesses.
With this change we adjust the logic in the script to use the
configuration from below tools/testing/selftests/bpf/configs/ instead
of pulling it over the network.

This change integrates libbpf maintained configurations and black/white
lists [0] into the repository, co-located with the BPF selftests themselves.
We minimize the kernel configurations to keep future updates as small as
possible [1].
Furthermore, we make both kernel configurations build on top of the existing
configuration tools/testing/selftests/bpf/config (to be concatenated before
build). Lastly, we replaced the terms blacklist & whitelist with denylist and
allowlist, respectively.

This change makes sure to sort the existing minimal kernel configuration
containing options required for running BPF selftests alphabetically.
Doing so will make it easier to diff it against other configurations,
which in turn helps with maintaining disjunct config files that build on
top of each other. It also helped identify the CONFIG_IPV6_GRE being set
twice and removes one of the occurrences.
Lastly, we change NET_CLS_BPF from 'm' to 'y'. Having this option as 'm'
will cause failures of the btf_skc_cls_ingress selftest.

Previously, the smc and smc_diag modules were automatically loaded as
dependencies of the ism module whenever an ISM device was present.
With the pending rework of the ISM API, the smc module will no longer
automatically be loaded in presence of an ISM device. Usage of an AF_SMC
socket will still trigger loading of the smc modules, but usage of a
netlink socket will not.
This is addressed by setting the correct module aliases.

We try using cancel_delayed_work_sync() to prevent the work from
enabling NAPI. This is insufficient since we don't disable the source
of the refill work scheduling. This means an NAPI poll callback after
cancel_delayed_work_sync() can schedule the refill work then can
re-enable the NAPI that leads to use-after-free [1].
Since the work can enable NAPI, we can't simply disable NAPI before
calling cancel_delayed_work_sync(). So fix this by introducing a
dedicated boolean to control whether or not the work could be
scheduled from NAPI.

The mcp251xfd uses a similar pattern except that it does some

The previous format specifier `%hhu` describes a u8 but our arguments
are wider than this which means bits are potentially being lost.
Variadic functions (printf-like) undergo default argument promotion.
Documentation/core-api/printk-formats.rst specifically recommends using
the promoted-to-type's format flag.
As per C11 6.3.1.1:
(https://www.open-std.org/jtc1/sc22/wg14/www/docs/n1548.pdf) `If an int
can represent all values of the original type ..., the value is
converted to an int; otherwise, it is converted to an unsigned int.
These are called the integer promotions.` Thus it makes sense to change
`%hhu` to `%d` for both instances of the warning.

Commit 56c8ccf331 ("ath11k: Add register access logic for WCN6750")
regressed QCN9074. With the above mentioned commit, writes are failing
for some registers on QCN9074 although the device seems to work
normally.
ath11k_pci 0000:03:00.0: failed to set pcie link register0x01e0e0a8: 0xffffffff != 0x00000010
ath11k_pci 0000:03:00.0: failed to set sysclk: -110
PCIe devices in ath11k (QCA6390, WCN6855, QCN9074, WCN6750) use window
concept for register accesses. There are two schemes, dynamic & static
window.
In dynamic window scheme, a single window(region in the BAR) is mapped
either to CE or DP register windows at any give time. QCA6390 & WCN6855
follow this scheme for register accesses.
In static window scheme, CE & DP register windows are statically mapped
to separate regions with in the BAR so that there is no switching of
register windows between CE & DP register accesses. QCN9074 & WCN6750
follow this scheme although the window start offsets are different for
QCN9074 & WCN6750.
QCN9074 uses 3rd & 2nd window for DP & CE register accesses respectively
whereas WCN6750 uses 1st & 2nd window for DP & CE. In QCN9074, along with
2nd & 3rd windows, 1st window is also used for certain configurations
which commit 56c8ccf331 ("ath11k: Add register access logic for WCN6750")
did not account for and hence the regression.
Fix this by going back to the original way of accessing the registers on
QCN9074. Since this diverges from WCN6750 way of accessing registers, it
is required to register window_read32/window_write32() pci_ops for WCN6750.
We can also get rid of dp_window_idx & ce_window_idx members in hw_params,
so remove them.
Also add a new API ath11k_pcic_register_pci_ops() for registering pci_ops
to the ath11k core. This API checks for mandatory pci_ops() and reports
error if those are missing. Also initialize unused pci_ops to NULL.

net: dsa: microchip: add support for phylink mac config and link up
This patch series add support common phylink mac config and link up for the ksz
series switches. At present, ksz8795 and ksz9477 doesn't implement the phylink
mac config and link up. It configures the mac interface in the port setup hook.
ksz8830 series switch does not mac link configuration. For lan937x switches, in
the part support patch series has support only for MII and RMII configuration.
Some group of switches have some register address and bit fields common and
others are different. So, this patch aims to have common phylink implementation
which configures the register based on the chip id.
Changes in v2
- combined the modification of duplex, tx_pause and rx_pause into single
function.
Changes in v1
- Squash the reading rgmii value from dt to patch which apply the rgmii value
- Created the new function ksz_port_set_xmii_speed
- Seperated the namespace values for xmii_ctrl_0 and xmii_ctrl_1 register

register based on the interface selected in phylink mac config. There
are two rgmii port in LAN937x and value to be loaded in the register
vary depends on the port selected.

This patch add the common ksz_set_xmii function for ksz series switch
and update the lan937x code phylink mac config. The register address for
the ksz8795 is Port 5 Interface control 6 and for all other switch is
xMII Control 1.
The bit value for selecting the interface is same for
KSZ8795 and KSZ9893 are same. The bit values for KSZ9477 and lan973x are
same. So, this patch add the bit value for each switches in
ksz_chip_data and configure the registers based on the chip id.

This patch add common function for configuring the Full/Half duplex and
transmit/receive flow control. KSZ8795 uses the Global control register
4 for configuring the duplex and flow control, whereas all other KSZ9477
based switch uses the xMII Control 0 register.

This patch adds the function for configuring the 100/10Mbps speed
selection for the ksz switches. KSZ8795 switch uses Global control 4
register 0x06 bit 4 for choosing 100/10Mpbs. Other switches uses xMII
control 1 0xN300 for it.
For KSZ8795, if the bit is set then 10Mbps is chosen and if bit is
clear then 100Mbps chosen. For all other switches it is other way
around, if the bit is set then 100Mbps is chosen.
So, this patch add the generic function for ksz switch to select the
100/10Mbps speed selection. While configuring, first it disables the
gigabit functionality and then configure the respective speed.

This patch add helper function for setting and getting the gigabit
enable for the ksz series switch. KSZ8795 switch has different register
address compared to all other ksz switches. KSZ8795 series uses the Port
5 Interface control 6 Bit 6 for configuring the 1Gbps or 100/10Mbps
speed selection. All other switches uses the xMII control 1 0xN301
register Bit6 for gigabit.
Further, for KSZ8795 & KSZ9893 switches if bit 1 then 1Gbps is chosen
and if bit 0 then 100/10Mbps is chosen. It is other way around for
other switches bit 0 is for 1Gbps. So, this patch implements the common
function for configuring the gigabit set and get capability.

New subflows are created within the kernel using O_NONBLOCK, so
EINPROGRESS is the expected return value from kernel_connect().
__mptcp_subflow_connect() has the correct logic to consider EINPROGRESS
to be a successful case, but it has also used that error code as its
return value.
Before v5.19 this was benign: all the callers ignored the return
value. Starting in v5.19 there is a MPTCP_PM_CMD_SUBFLOW_CREATE generic
netlink command that does use the return value, so the EINPROGRESS gets
propagated to userspace.
Make __mptcp_subflow_connect() always return 0 on success instead.

Florian Westphal says:
====================
netfilter updates for net
Three late fixes for netfilter:
1) If nf_queue user requests packet truncation below size of l3 header,
we corrupt the skb, then crash. Reject such requests.
2) add cond_resched() calls when doing cycle detection in the
nf_tables graph. This avoids softlockup warning with certain
rulesets.
3) Reject rulesets that use nftables 'queue' expression in family/chain
combinations other than those that are supported. Currently the ruleset
will load, but when userspace attempts to reinject you get WARN splat +
packet drops.
* git://git.kernel.org/pub/scm/linux/kernel/git/netfilter/nf:
netfilter: nft_queue: only allow supported familes and hooks
netfilter: nf_tables: add rescheduling points during loop detection walks
netfilter: nf_queue: do not allow packet truncation below transport header offset
