ASoC: Fixes for v6.9

A relatively large set of fixes here, the biggest piece of it is a
series correcting some problems with the delay reporting for Intel SOF
cards but there's a bunch of other things. Everything here is driver
specific except for a fix in the core for an issue with sign extension
handling volume controls.

Merge tag 'net-next-6.9' of git://git.kernel.org/pub/scm/linux/kernel/git/netdev/net-next

Pull networking updates from Jakub Kicinski:
"Core & protocols:

- Large effort by Eric to lower rtnl_lock pressure and remove locks:

- Make commonly used parts of rtnetlink (address, route dumps
etc) lockless, protected by RCU instead of rtnl_lock.

- Add a netns exit callback which already holds rtnl_lock,
allowing netns exit to take rtnl_lock once in the core instead
of once for each driver / callback.

- Remove locks / serialization in the socket diag interface.

- Remove 6 calls to synchronize_rcu() while holding rtnl_lock.

- Remove the dev_base_lock, depend on RCU where necessary.

- Support busy polling on a per-epoll context basis. Poll length and
budget parameters can be set independently of system defaults.

- Introduce struct net_hotdata, to make sure read-mostly global
config variables fit in as few cache lines as possible.

- Add optional per-nexthop statistics to ease monitoring / debug of
ECMP imbalance problems.

- Support TCP_NOTSENT_LOWAT in MPTCP.

- Ensure that IPv6 temporary addresses' preferred lifetimes are long
enough, compared to other configured lifetimes, and at least 2 sec.

- Support forwarding of ICMP Error messages in IPSec, per RFC 4301.

- Add support for the independent control state machine for bonding
per IEEE 802.1AX-2008 5.4.15 in addition to the existing coupled
control state machine.

- Add "network ID" to MCTP socket APIs to support hosts with multiple
disjoint MCTP networks.

- Re-use the mono_delivery_time skbuff bit for packets which user
space wants to be sent at a specified time. Maintain the timing
information while traversing veth links, bridge etc.

- Take advantage of MSG_SPLICE_PAGES for RxRPC DATA and ACK packets.

- Simplify many places iterating over netdevs by using an xarray
instead of a hash table walk (hash table remains in place, for use
on fastpaths).

- Speed up scanning for expired routes by keeping a dedicated list.

- Speed up "generic" XDP by trying harder to avoid large allocations.

- Support attaching arbitrary metadata to netconsole messages.

Things we sprinkled into general kernel code:

- Enforce VM_IOREMAP flag and range in ioremap_page_range and
introduce VM_SPARSE kind and vm_area_[un]map_pages (used by
bpf_arena).

- Rework selftest harness to enable the use of the full range of ksft
exit code (pass, fail, skip, xfail, xpass).

Netfilter:

- Allow userspace to define a table that is exclusively owned by a
daemon (via netlink socket aliveness) without auto-removing this
table when the userspace program exits. Such table gets marked as
orphaned and a restarting management daemon can re-attach/regain
ownership.

- Speed up element insertions to nftables' concatenated-ranges set
type. Compact a few related data structures.

BPF:

- Add BPF token support for delegating a subset of BPF subsystem
functionality from privileged system-wide daemons such as systemd
through special mount options for userns-bound BPF fs to a trusted
& unprivileged application.

- Introduce bpf_arena which is sparse shared memory region between
BPF program and user space where structures inside the arena can
have pointers to other areas of the arena, and pointers work
seamlessly for both user-space programs and BPF programs.

- Introduce may_goto instruction that is a contract between the
verifier and the program. The verifier allows the program to loop
assuming it's behaving well, but reserves the right to terminate
it.

- Extend the BPF verifier to enable static subprog calls in spin lock
critical sections.

- Support registration of struct_ops types from modules which helps
projects like fuse-bpf that seeks to implement a new struct_ops
type.

- Add support for retrieval of cookies for perf/kprobe multi links.

- Support arbitrary TCP SYN cookie generation / validation in the TC
layer with BPF to allow creating SYN flood handling in BPF
firewalls.

- Add code generation to inline the bpf_kptr_xchg() helper which
improves performance when stashing/popping the allocated BPF
objects.

Wireless:

- Add SPP (signaling and payload protected) AMSDU support.

- Support wider bandwidth OFDMA, as required for EHT operation.

Driver API:

- Major overhaul of the Energy Efficient Ethernet internals to
support new link modes (2.5GE, 5GE), share more code between
drivers (especially those using phylib), and encourage more
uniform behavior. Convert and clean up drivers.

- Define an API for querying per netdev queue statistics from
drivers.

- IPSec: account in global stats for fully offloaded sessions.

- Create a concept of Ethernet PHY Packages at the Device Tree level,
to allow parameterizing the existing PHY package code.

- Enable Rx hashing (RSS) on GTP protocol fields.

Misc:

- Improvements and refactoring all over networking selftests.

- Create uniform module aliases for TC classifiers, actions, and
packet schedulers to simplify creating modprobe policies.

- Address all missing MODULE_DESCRIPTION() warnings in networking.

- Extend the Netlink descriptions in YAML to cover message
encapsulation or "Netlink polymorphism", where interpretation of
nested attributes depends on link type, classifier type or some
other "class type".

Merge patch series "can: esd: add support for esd GmbH PCIe/402 CAN interface"

Stefan Mätje <stefan.maetje@esd.eu> says:

The purpose of this patch is to introduce a new CAN driver to support
the esd GmbH 402 family of CAN interface boards. The hardware design
is based on a CAN controller implemented in a FPGA attached to a
PCIe link.

More information on these boards can be found following the links
included in the commit message.

This patch supports all boards but will operate the CAN-FD capable
boards only in Classic-CAN mode. The CAN-FD support will be added
when the initial patch has stabilized.

The patch is reuses the previous work of my former colleague:
Link: https://lore.kernel.org/linux-can/1426592308-23817-1-git-send-email-thomas.koerper@esd.eu

The patch is based on the linux-can-next main branch.

Changed in v11:
No functional, only editorial changes due to feedback on v10.
- Make lifetime of macros used for hardware timestamp calculation
very short by #undef-ing them after use.
- Fixed insertion order of new entry in MAINTAINERS file.

Changed in v10:
Most changes due to feedback by Vincent Mailhol
https://lore.kernel.org/linux-can/CAMZ6RqLOAC930GNOU+pWuoi6FgYwFOuFrSyAzVjvE2fuVgy8oA@mail.gmail.com
- Add support for ethtool operations by using default operations
provided by the can_dev module for drivers with hardware time
stamp support.
- Factor out core unregistration into pci402_unregister_core().
- Factor out getting next TX fifo index into acc_tx_fifo_next().
- Stop counting alloc_can_err_skb() failures in rx_dropped statistic.
- Add CAN_ERR_CNT flag in CAN error frames as needed.
- Rework function acc_reset_fpga(). To clear I^2C bus enable bit
is not necessary after FPGA reset.
- Simplify struct acc_bmmsg_rxtxdone layout.
- Additional non functional changes due to feedback by Vincent
- Some spelling corrections: ESDACC -> esdACC

Changes in v9:
- Fix returning success error code in case of allocation failure in
pci402_probe().

Changes in v8:
- Rebased to 6.6-rc2 on linux-can-next branch main

Changes in v7:
- Numerous changes. Find the quoted with inline comments about changes
below after the changes list. Stuff that I don't understand and
where I have questions is marked with ????.
Unfortunately I will be AFK till 28th of November.

Changes in v6:
- Fixed the statistic handling of RX overrun errors and increase
net_device_stats::rx_errors instead of net_device_stats::rx_dropped.
- Added a patch to not increase rx statistics when generating a CAN
rx error message frame as suggested on the linux-can list.
- Added a patch to not not increase rx_bytes statistics for RTR frames
as suggested on the linux-can list.

The last two patches change the statistics handling from the previous
style used in other drivers to the newly suggested one.

Changes in v5:
- Added the initialization for netdev::dev_port as it is implemented
for another CAN driver. See
https://lore.kernel.org/linux-can/20211026180553.1953189-1-mailhol.vincent@wanadoo.fr

Changes in v4:
- Fixed the build failure on ARCH=arm64 that was found by the Intel
kernel test robot. See
https://lore.kernel.org/linux-can/202109120608.7ZbQXkRh-lkp@intel.com

Removed error monitoring code that used GCC's built-in compiler
functions for atomic access (__sync_* functions). GCC versions
after 9 (tested with "gcc-10 (Ubuntu 10.3.0-1ubuntu1~20.04)")
don't implement the intrinsic atomic as in-line code but call
"__aarch64_ldadd4_acq_rel" on arm64. This GCC support function
is not exported by the kernel and therefore the module build
post-processing fails.

Removed that code because the error monitoring never showed a
problem during the development this year.

Changes in v3:
- Rework the bus-off restart logic in acc_set_mode() and
handle_core_msg_errstatechange() to call netif_wake_queue() from the
error active event.
- Changed pci402_init_card() to allocate a variable sized array of
struct acc_core using devm_kcalloc() instead of using a fixed size
array in struct pci402_card.
- Changed handle_core_msg_txabort() to release aborted TX frames in
TX FIFO order.
- Fixed the acc_close() function to abort all pending TX request in
esdACC controller.
- Fixed counting of transmit aborts in handle_core_msg_txabort().
It is now done like in can_flush_echo_skb().
- Fixed handle_core_msg_buserr() to create error frames including the
CAN RX and TX error counters that were missing.
- Fixed acc_set_bittiming() neither to touch LOM mode setting of
esdACC controller nor to enter or leave RESET mode.
The esdACC controller is going active on the CAN bus in acc_open()
and is going inactive (RESET mode) again in acc_close().
- Rely on the automatic release of memory fetched by devm_kzalloc().
But still use devm_irq_free() explicitely to make sure that the
interrupt handler is disconnected at that point.
This avoids a possible crash in non-MSI mode due to the IRQ
triggered by another device on the same PCI IRQ line.
- Changed to use DMA map API instead of pci_*_consistent compatibility
wrappers.
- Fixed stale email references and updated copyright information.
- Removed any traces of future CAN-FD support.

Changes in v2:
- Avoid warning triggered by -Wshift-count-overflow on architectures
with 32-bit dma_addr_t.
- Fixed Makefile not to build the kernel module always. Doing this
renamed esd402_pci.c to esd_402_pci-core.c as recommended by Marc.

can: esd: add support for esd GmbH PCIe/402 CAN interface family

This patch adds support for the PCI based PCIe/402 CAN interface family
from esd GmbH that is available with various form factors
(https://esd.eu/en/products/402-series-can-interfaces).

All boards utilize a FPGA based CAN controller solution developed
by esd (esdACC). For more information on the esdACC see
https://esd.eu/en/products/esdacc.

This driver detects all available CAN interface board variants of
the family but atm. operates the CAN-FD capable devices in
Classic-CAN mode only! A later patch will introduce the CAN-FD
functionality in this driver.

Merge tag 'net-next-6.4' of git://git.kernel.org/pub/scm/linux/kernel/git/netdev/net-next

Pull networking updates from Paolo Abeni:
"Core:

- Introduce a config option to tweak MAX_SKB_FRAGS. Increasing the
default value allows for better BIG TCP performances

- Reduce compound page head access for zero-copy data transfers

- RPS/RFS improvements, avoiding unneeded NET_RX_SOFTIRQ when
possible

- Threaded NAPI improvements, adding defer skb free support and
unneeded softirq avoidance

- Address dst_entry reference count scalability issues, via false
sharing avoidance and optimize refcount tracking

- Add lockless accesses annotation to sk_err[_soft]

- Optimize again the skb struct layout

- Extends the skb drop reasons to make it usable by multiple
subsystems

- Better const qualifier awareness for socket casts

BPF:

- Add skb and XDP typed dynptrs which allow BPF programs for more
ergonomic and less brittle iteration through data and
variable-sized accesses

- Add a new BPF netfilter program type and minimal support to hook
BPF programs to netfilter hooks such as prerouting or forward

- Add more precise memory usage reporting for all BPF map types

- Adds support for using {FOU,GUE} encap with an ipip device
operating in collect_md mode and add a set of BPF kfuncs for
controlling encap params

- Allow BPF programs to detect at load time whether a particular
kfunc exists or not, and also add support for this in light
skeleton

- Bigger batch of BPF verifier improvements to prepare for upcoming
BPF open-coded iterators allowing for less restrictive looping
capabilities

- Rework RCU enforcement in the verifier, add kptr_rcu and enforce
BPF programs to NULL-check before passing such pointers into kfunc

- Add support for kptrs in percpu hashmaps, percpu LRU hashmaps and
in local storage maps

- Enable RCU semantics for task BPF kptrs and allow referenced kptr
tasks to be stored in BPF maps

- Add support for refcounted local kptrs to the verifier for allowing
shared ownership, useful for adding a node to both the BPF list and
rbtree

- Add BPF verifier support for ST instructions in
convert_ctx_access() which will help new -mcpu=v4 clang flag to
start emitting them

- Add ARM32 USDT support to libbpf

- Improve bpftool's visual program dump which produces the control
flow graph in a DOT format by adding C source inline annotations

Protocols:

- IPv4: Allow adding to IPv4 address a 'protocol' tag. Such value
indicates the provenance of the IP address

- IPv6: optimize route lookup, dropping unneeded R/W lock acquisition

- Add the handshake upcall mechanism, allowing the user-space to
implement generic TLS handshake on kernel's behalf

- Bridge: support per-{Port, VLAN} neighbor suppression, increasing
resilience to nodes failures

- SCTP: add support for Fair Capacity and Weighted Fair Queueing
schedulers

- MPTCP: delay first subflow allocation up to its first usage. This
will allow for later better LSM interaction

- xfrm: Remove inner/outer modes from input/output path. These are
not needed anymore

- WiFi:
- reduced neighbor report (RNR) handling for AP mode
- HW timestamping support
- support for randomized auth/deauth TA for PASN privacy
- per-link debugfs for multi-link
- TC offload support for mac80211 drivers
- mac80211 mesh fast-xmit and fast-rx support
- enable Wi-Fi 7 (EHT) mesh support

Netfilter:

- Add nf_tables 'brouting' support, to force a packet to be routed
instead of being bridged

- Update bridge netfilter and ovs conntrack helpers to handle IPv6
Jumbo packets properly, i.e. fetch the packet length from
hop-by-hop extension header. This is needed for BIT TCP support

- The iptables 32bit compat interface isn't compiled in by default
anymore

- Move ip(6)tables builtin icmp matches to the udptcp one. This has
the advantage that icmp/icmpv6 match doesn't load the
iptables/ip6tables modules anymore when iptables-nft is used

- Extended netlink error report for netdevice in flowtables and
netdev/chains. Allow for incrementally add/delete devices to netdev
basechain. Allow to create netdev chain without device

Driver API:

- Remove redundant Device Control Error Reporting Enable, as PCI core
has already error reporting enabled at enumeration time

- Move Multicast DB netlink handlers to core, allowing devices other
then bridge to use them

- Allow the page_pool to directly recycle the pages from safely
localized NAPI

- Implement lockless TX queue stop/wake combo macros, allowing for
further code de-duplication and sanitization

- Add YNL support for user headers and struct attrs

- Add partial YNL specification for devlink

- Add partial YNL specification for ethtool

- Add tc-mqprio and tc-taprio support for preemptible traffic classes

- Add tx push buf len param to ethtool, specifies the maximum number
of bytes of a transmitted packet a driver can push directly to the
underlying device

- Add basic LED support for switch/phy

- Add NAPI documentation, stop relaying on external links

- Convert dsa_master_ioctl() to netdev notifier. This is a
preparatory work to make the hardware timestamping layer selectable
by user space

- Add transceiver support and improve the error messages for CAN-FD
controllers

New hardware / drivers:

Merge patch series "can: bxcan: add support for ST bxCAN controller"

Dario Binacchi <dario.binacchi@amarulasolutions.com> says:

The series adds support for the basic extended CAN controller (bxCAN)
found in many low- to middle-end STM32 SoCs.

The driver has been tested on the stm32f469i-discovery board with a
kernel version 5.19.0-rc2 in loopback + silent mode:

ip link set can0 type can bitrate 125000 loopback on listen-only on
ip link set up can0
candump can0 -L &
cansend can0 300#AC.AB.AD.AE.75.49.AD.D1

For uboot and kernel compilation, as well as for rootfs creation I used
buildroot:

make stm32f469_disco_sd_defconfig
make

but I had to patch can-utils and busybox as can-utils and iproute are
not compiled for MMU-less microcotrollers. In the case of can-utils,
replacing the calls to fork() with vfork(), I was able to compile the
package with working candump and cansend applications, while in the
case of iproute, I ran into more than one problem and finally I decided
to extend busybox's ip link command for CAN-type devices. I'm still
wondering if it was really necessary, but this way I was able to test
the driver.

Changes in v10: https://lore.kernel.org/all/20230328073328.3949796-1-dario.binacchi@amarulasolutions.com
- Fix errors running 'make DT_CHECKER_FLAGS=-m dt_binding_check'.
Fix the "st,can-primary" description removing the "Note:" word that
caused the failure.
- Slightly change the note text at the top of the driver module. No
functional changes.

Changes in v9: https://lore.kernel.org/all/20230327201630.3874028-1-dario.binacchi@amarulasolutions.com
- Fix commit description formatting. No semantic changes have been made.

- Do not enable the clock in probe and enable/disable it in open/close.
- Return IRQ_NONE if no IRQ is active.

Changes in v7: https://lore.kernel.org/all/20230116175152.2839455-1-dario.binacchi@amarulasolutions.com
- Add Vincent Mailhol's Reviewed-by tag.
- Remove all unused macros for reading/writing the controller registers.
- Add CAN_ERR_CNT flag to notify availability of error counter.
- Move the "break" before the newline in the switch/case statements.
- Print the mnemotechnic instead of the error value in each netdev_err().
- Remove the debug print for timings parameter.

- Add Rob Herring's Acked-by tag.
- Add Rob Herring's Reviewed-by tag.
- Put static in front of bxcan_enable_filters() definition.

Changes in v4: https://lore.kernel.org/all/20220925175209.1528960-1-dario.binacchi@amarulasolutions.com
- Remove "st,stm32f4-bxcan-core" compatible. In this way the can nodes
(compatible "st,stm32f4-bxcan") are no longer children of a parent
node with compatible "st,stm32f4-bxcan-core".
- Add the "st,gcan" property (global can memory) to can nodes which
references a "syscon" node containing the shared clock and memory
addresses.
- Replace the node can@40006400 (compatible "st,stm32f4-bxcan-core")
with the gcan@40006600 node ("sysnode" compatible). The gcan node
contains clocks and memory addresses shared by the two can nodes
of which it's no longer the parent.
- Add to can nodes the "st,gcan" property (global can memory) which
references the gcan@40006600 node ("sysnode compatibble).
- Add "dt-bindings: arm: stm32: add compatible for syscon gcan node" patch.
- Drop the core driver. Thus bxcan-drv.c has been renamed to bxcan.c and
moved to the drivers/net/can folder. The drivers/net/can/bxcan directory
has therefore been removed.
- Use the regmap_*() functions to access the shared memory registers.
- Use spinlock to protect bxcan_rmw().
- Use 1 space, instead of tabs, in the macros definition.
- Drop clock ref-counting.
- Drop unused code.
- Drop the _SHIFT macros and use FIELD_GET()/FIELD_PREP() directly.
- Add BXCAN_ prefix to lec error codes.
- Add the macro BXCAN_RX_MB_NUM.
- Enable time triggered mode and use can_rx_offload().
- Use readx_poll_timeout() in function with timeouts.
- Loop from tail to head in bxcan_tx_isr().
- Check bits of tsr register instead of pkts variable in bxcan_tx_isr().
- Don't return from bxcan_handle_state_change() if skb/cf are NULL.
- Enable/disable the generation of the bus error interrupt depending
on can.ctrlmode & CAN_CTRLMODE_BERR_REPORTING.
- Don't return from bxcan_handle_bus_err() if skb is NULL.
- Drop statistics updating from bxcan_handle_bus_err().
- Add an empty line in front of 'return IRQ_HANDLED;'
- Rename bxcan_start() to bxcan_chip_start().
- Rename bxcan_stop() to bxcan_chip_stop().
- Disable all IRQs in bxcan_chip_stop().
- Rename bxcan_close() to bxcan_ndo_stop().
- Use writel instead of bxcan_rmw() to update the dlc register.

Changes in v3: https://lore.kernel.org/all/20220828133329.793324-1-dario.binacchi@amarulasolutions.com
- Remove 'Dario Binacchi <dariobin@libero.it>' SOB.
- Add description to the parent of the two child nodes.
- Move "patterProperties:" after "properties: in top level before "required".
- Add "clocks" to the "required:" list of the child nodes.
- Remove 'Dario Binacchi <dariobin@libero.it>' SOB.
- Add "clocks" to can@0 node.
- Remove 'Dario Binacchi <dariobin@libero.it>' SOB.
- Remove a blank line.
- Remove 'Dario Binacchi <dariobin@libero.it>' SOB.
- Fix the documentation file path in the MAINTAINERS entry.
- Do not increment the "stats->rx_bytes" if the frame is remote.
- Remove pr_debug() call from bxcan_rmw().

Changes in v2: https://lore.kernel.org/all/20220820082936.686924-1-dario.binacchi@amarulasolutions.com
- Change the file name into 'st,stm32-bxcan-core.yaml'.
- Rename compatibles:
- st,stm32-bxcan-core -> st,stm32f4-bxcan-core
- st,stm32-bxcan -> st,stm32f4-bxcan
- Rename master property to st,can-master.
- Remove the status property from the example.
- Put the node child properties as required.
- Remove a blank line.
- Fix sparse errors.
- Create a MAINTAINERS entry.
- Remove the print of the registers address.
- Remove the volatile keyword from bxcan_rmw().

can: bxcan: add support for ST bxCAN controller

Add support for the basic extended CAN controller (bxCAN) found in many
low- to middle-end STM32 SoCs. It supports the Basic Extended CAN
protocol versions 2.0A and B with a maximum bit rate of 1 Mbit/s.

The controller supports two channels (CAN1 as primary and CAN2 as
secondary) and the driver can enable either or both of the channels. They
share some of the required logic (e. g. clocks and filters), and that means
you cannot use the secondary CAN without enabling some hardware resources
managed by the primary CAN.

Each channel has 3 transmit mailboxes, 2 receive FIFOs with 3 stages and
28 scalable filter banks.
It also manages 4 dedicated interrupt vectors:
- transmit interrupt
- FIFO 0 receive interrupt
- FIFO 1 receive interrupt
- status change error interrupt

Driver uses all 3 available mailboxes for transmission and FIFO 0 for
reception. Rx filter rules are configured to the minimum. They accept
all messages and assign filter 0 to CAN1 and filter 14 to CAN2 in
identifier mask mode with 32 bits width. It enables and uses transmit,
receive buffers for FIFO 0 and error and status change interrupts.
