Merge tag 'soc-drivers-6.14' of git://git.kernel.org/pub/scm/linux/kernel/git/soc/soc
Pull SoC driver updates from Arnd Bergmann:
"These are changes to SoC specific drivers and DT bindings that don't
have a separate subsystem tree, or that get grouped here for
simplicity.
Nothing out of the ordinary for the 6.14 release here:
- Most of the updates are for Qualcomm specific drivers, adding
support for additional SoCs in the exssting drivers, and support
for wrapped encryption key access in the SCM firmware.
- The Arm SCMI firmware code gains support for having multiple
instances of firmware running, and better module auto loading.
- A few minor updates for litex, samsung, ti, tegra, mediatek, imx
and renesas platforms.
- Reset controller updates for amlogic, to add support for the A1 soc
and clean up the existing code.
- Memory controller updates for ti davinci aemif, refactoring the
code and adding a few interfaces to other drivers"

net: mscc: ocelot: add TX timestamping statistics
Add an u64 hardware timestamping statistics structure for each ocelot port. Export a function from the common switch library for reporting them to ethtool. This is called by the ocelot switchdev front-end for now. Note that for the switchdev driver, we report the one-step PTP packets as unconfirmed, even though in principle, for some transmission mechanisms like FDMA, we may be able to confirm transmission and bump the "pkts" counter in ocelot_fdma_tx_cleanup() instead. I don't have access to hardware which uses the switchdev front-end, and I've kept the implementation simple.

Having the aux registration helper along with the registered driver is not great dependency wise. It does not allow the registering driver to be properly decoupled from the registered auxiliary driver. Drop the registration helper from the amlogic auxiliary reset driver.

net: mscc: ocelot: be resilient to loss of PTP packets during transmission
The Felix DSA driver presents unique challenges that make the simplistic
ocelot PTP TX timestamping procedure unreliable: any transmitted packet
may be lost in hardware before it ever leaves our local system.
This may happen because there is congestion on the DSA conduit, the
switch CPU port or even user port (Qdiscs like taprio may delay packets
indefinitely by design).
The technical problem is that the kernel, i.e. ocelot_port_add_txtstamp_skb(),
runs out of timestamp IDs eventually, because it never detects that
packets are lost, and keeps the IDs of the lost packets on hold
indefinitely. The manifestation of the issue once the entire timestamp
ID range becomes busy looks like this in dmesg:
mscc_felix 0000:00:00.5: port 0 delivering skb without TX timestamp
mscc_felix 0000:00:00.5: port 1 delivering skb without TX timestamp
At the surface level, we need a timeout timer so that the kernel knows a
timestamp ID is available again. But there is a deeper problem with the
implementation, which is the monotonically increasing ocelot_port->ts_id.
In the presence of packet loss, it will be impossible to detect that and
reuse one of the holes created in the range of free timestamp IDs.
What we actually need is a bitmap of 63 timestamp IDs tracking which one
is available. That is able to use up holes caused by packet loss, but
also gives us a unique opportunity to not implement an actual timer_list
for the timeout timer (very complicated in terms of locking).
We could only declare a timestamp ID stale on demand (lazily), aka when
there's no other timestamp ID available. There are pros and cons to this
approach: the implementation is much more simple than per-packet timers
would be, but most of the stale packets would be quasi-leaked - not
really leaked, but blocked in driver memory, since this algorithm sees
no reason to free them.
An improved technique would be to check for stale timestamp IDs every
time we allocate a new one. Assuming a constant flux of PTP packets,
this avoids stale packets being blocked in memory, but of course,
packets lost at the end of the flux are still blocked until the flux
resumes (nobody left to kick them out).
Since implementing per-packet timers is way too complicated, this should
be good enough.
Testing procedure:
Persistently block traffic class 5 and try to run PTP on it:

Notice that in this new usage pattern, a non-congested port should
basically use timestamp ID 0 all the time, progressing to higher numbers
only if there are unacknowledged timestamps in flight. Compare this to
the old usage, where the timestamp ID used to monotonically increase
modulo OCELOT_MAX_PTP_ID.
In terms of implementation, this simplifies the bookkeeping of the
ocelot_port :: ts_id and ptp_skbs_in_flight. Since we need to traverse
the list of two-step timestampable skbs for each new packet anyway, the
information can already be computed and does not need to be stored.
Also, ocelot_port->tx_skbs is always accessed under the switch-wide
ocelot->ts_id_lock IRQ-unsafe spinlock, so we don't need the skb queue's
lock and can use the unlocked primitives safely.
This problem was actually detected using the tc-taprio offload, and is
causing trouble in TSN scenarios, which Felix (NXP LS1028A / VSC9959)
supports but Ocelot (VSC7514) does not. Thus, I've selected the commit
to blame as the one adding initial timestamping support for the Felix
switch.

possible out of RTNL lock
- convert all phonet doit() and dumpit() handlers to RCU
- convert IPv4 addresses manipulation to per-netns RTNL
- convert virtual interface creation to per-netns RTNL
the per-netns lock infrastructure is guarded by the
CONFIG_DEBUG_NET_SMALL_RTNL knob, disabled by default ad interim.
- Introduce NAPI suspension, to efficiently switching between busy
polling (NAPI processing suspended) and normal processing.
- Migrate the IPv4 routing input, output and control path from direct
ToS usage to DSCP macros. This is a work in progress to make ECN
handling consistent and reliable.
- Add drop reasons support to the IPv4 rotue input path, allowing
better introspection in case of packets drop.
- Make FIB seqnum lockless, dropping RTNL protection for read access.
- Make inet{,v6} addresses hashing less predicable.
- Allow providing timestamp OPT_ID via cmsg, to correlate TX packets
and timestamps
Things we sprinkled into general kernel code:
- Add small file operations for debugfs, to reduce the struct ops
size.
- Refactoring and optimization for the implementation of page_frag
API, This is a preparatory work to consolidate the page_frag
implementation.
Netfilter:
- Optimize set element transactions to reduce memory consumption
- Extended netlink error reporting for attribute parser failure.
- Make legacy xtables configs user selectable, giving users the
option to configure iptables without enabling any other config.
- Address a lot of false-positive RCU issues, pointed by recent CI
improvements.
BPF:
- Put xsk sockets on a struct diet and add various cleanups. Overall,
this helps to bump performance by 12% for some workloads.
- Extend BPF selftests to increase coverage of XDP features in
combination with BPF cpumap.
- Optimize and homogenize bpf_csum_diff helper for all archs and also
add a batch of new BPF selftests for it.
- Extend netkit with an option to delegate skb->{mark,priority}
scrubbing to its BPF program.
- Make the bpf_get_netns_cookie() helper available also to tc(x) BPF
programs.
Protocols:
- Introduces 4-tuple hash for connected udp sockets, speeding-up
significantly connected sockets lookup.
- Add a fastpath for some TCP timers that usually expires after
close, the socket lock contention.
- Add inbound and outbound xfrm state caches to speed up state
lookups.
- Avoid sending MPTCP advertisements on stale subflows, reducing
risks on loosing them.
- Make neighbours table flushing more scalable, maintaining per
device neigh lists.
Driver API:
- Introduce a unified interface to configure transmission H/W
shaping, and expose it to user-space via generic-netlink.
- Add support for per-NAPI config via netlink. This makes napi
configuration persistent across queues removal and re-creation.
Requires driver updates, currently supported drivers are:
nVidia/Mellanox mlx4 and mlx5, Broadcom brcm and Intel ice.
- Add ethtool support for writing SFP / PHY firmware blocks.
- Track RSS context allocation from ethtool core.
- Implement support for mirroring to DSA CPU port, via TC mirror
offload.
- Consolidate FDB updates notification, to avoid duplicates on
device-specific entries.
- Expose DPLL clock quality level to the user-space.
- Support master-slave PHY config via device tree.
Tests and tooling:
- forwarding: introduce deferred commands, to simplify the cleanup
phase
Drivers:
- Updated several drivers - Amazon vNic, Google vNic, Microsoft vNic,
Intel e1000e and Broadcom Tigon3 - to use netdev-genl to link the
IRQs and queues to NAPI IDs, allowing busy polling and better
introspection.

soc: fsl_qbman: use be16_to_cpu() in qm_sg_entry_get_off()
struct qm_sg_entry :: offset is a 13-bit field, declared as __be16. When using be32_to_cpu(), a wrong value will be calculated on little endian systems (Arm), because type promotion from 16-bit to 32-bit, which is done before the byte swap and always in the CPU native endianness, changes the value of the scatter/gather list entry offset in big-endian interpretation (adds two zero bytes in the LSB interpretation). The result of the byte swap is ANDed with GENMASK(12, 0), so the result is always zero, because only those bytes added by type promotion remain after the application of the bit mask. The impact of the bug is that scatter/gather frames with a non-zero offset into the buffer are treated by the driver as if they had a zero offset. This is all in theory, because in practice, qm_sg_entry_get_off() has a single caller, where the bug is inconsequential, because at that call site the buffer offset will always be zero, as will be explained in the subsequent change.

Merge tag 'soc-drivers-6.12' of git://git.kernel.org/pub/scm/linux/kernel/git/soc/soc
Pull SoC driver updates from Arnd Bergmann:
"The driver updates seem larger this time around, with changes is many
of the SoC specific drivers, both the custom drivers/soc ones and the
closely related subsystems (memory, bus, firmware, reset, ...).
The at91 platform gains support for sam9x7 chips in the soc and power
management code. This is the latest variant of one of the oldest still
supported SoC families, using the ARM9 (ARMv5) core.
As usual, the qualcomm snapdragon platform gets a ton of updates in
many of their drivers to add more features and additional SoC support.
Most of these are somewhat firmware related as the platform has a
number of firmware based interfaces to the kernel. A notable addition
here is the inclusion of trace events to two of these drivers.
Herve Codina and Christophe Leroy are now sending updates for
drivers/soc/fsl/ code through the SoC tree, this contains both PowerPC
and Arm specific platforms and has previously been problematic to
maintain. The first update here contains support for newer PowerPC
variants and some cleanups.
The turris mox firmware driver has a number of updates, mostly
cleanups.
The Arm SCMI firmware driver gets a major rework to modularize the
existing code into separately loadable drivers for the various
transports, the addition of custom NXP i.MX9 interfaces and a number
of smaller updates.
The Arm FF-A firmware driver gets a feature update to support the v1.2
version of the specification.
The reset controller drivers have some smaller cleanups and a newly
added driver for the Intel/Mobileye EyeQ5/EyeQ6 MIPS SoCs.
The memory controller drivers get some cleanups and refactoring for
Tegra, TI, Freescale/NXP and a couple more platforms.
Finally there are lots of minor updates to firmware (raspberry pi,
tegra, imx), bus (sunxi, omap, tegra) and soc (rockchips, tegra,
amlogic, mediatek) drivers and their DT bindings"

net: mscc: ocelot: treat 802.1ad tagged traffic as 802.1Q-untagged
I was revisiting the topic of 802.1ad treatment in the Ocelot switch [0]
and realized that not only is its basic VLAN classification pipeline
improper for offloading vlan_protocol 802.1ad bridges, but also improper
for offloading regular 802.1Q bridges already.
Namely, 802.1ad-tagged traffic should be treated as VLAN-untagged by
bridged ports, but this switch treats it as if it was 802.1Q-tagged with
the same VID as in the 802.1ad header. This is markedly different to
what the Linux bridge expects; see the "other_tpid()" function in
tools/testing/selftests/net/forwarding/bridge_vlan_aware.sh.
An idea came to me that the VCAP IS1 TCAM is more powerful than I'm
giving it credit for, and that it actually overwrites the classified VID
before the VLAN Table lookup takes place. In other words, it can be
used even to save a packet from being dropped on ingress due to VLAN
membership.
Add a sophisticated TCAM rule hardcoded into the driver to force the
switch to behave like a Linux bridge with vlan_filtering 1 vlan_protocol
802.1Q.
Regarding the lifetime of the filter: eventually the bridge will
disappear, and vlan_filtering on the port will be restored to 0 for
standalone mode. Then the filter will be deleted.

net: mscc: ocelot: use ocelot_xmit_get_vlan_info() also for FDMA and register injection
Problem description ------------------- On an NXP LS1028A (felix DSA driver) with the following configuration: - ocelot-8021q tagging protocol - VLAN-aware bridge (with STP) spanning at least swp0 and swp1 - 8021q VLAN upper interfaces on swp0 and swp1: swp0.700, swp1.700 - ptp4l on swp0.700 and swp1.700 we see that the ptp4l instances do not see each other's traffic, and they all go to the grand master state due to the ANNOUNCE_RECEIPT_TIMEOUT_EXPIRES condition. Jumping to the conclusion for the impatient ------------------------------------------- There is a zero-day bug in the ocelot switchdev driver in the way it handles VLAN-tagged packet injection. The correct logic already exists in the source code, in function ocelot_xmit_get_vlan_info() added by commit |

net: Add struct kernel_ethtool_ts_info
In prevision to add new UAPI for hwtstamp we will be limited to the struct ethtool_ts_info that is currently passed in fixed binary format through the ETHTOOL_GET_TS_INFO ethtool ioctl. It would be good if new kernel code already started operating on an extensible kernel variant of that structure, similar in concept to struct kernel_hwtstamp_config vs struct hwtstamp_config. Since struct ethtool_ts_info is in include/uapi/linux/ethtool.h, here we introduce the kernel-only structure in include/linux/ethtool.h. The manual copy is then made in the function called by ETHTOOL_GET_TS_INFO.
