Pull networking updates from Jakub Kicinski:
"The zero-copy changes are relatively significant, but regression risk
should be contained. The feature needs to be used to cause trouble.
Also it feels like we got an order of magnitude more semi-automated
"refactoring" chaff than usual, I wonder if it's just us.
Core & protocols:
- Support Device Memory TCP, ability to zero-copy receive TCP
payloads to a DMABUF region of memory while packet headers land
separately in normal kernel buffers, and TCP processes then as
usual.
- The ability to read the PTP PHC (Physical Hardware Clock) alongside
MONOTONIC_RAW timestamps with PTP_SYS_OFFSET_EXTENDED. Previously
only CLOCK_REALTIME was supported.
- Allow matching on all bits of IP DSCP for routing decisions.
Previously we only supported on matching TOS bits in IPv4 which is
a narrower interpretation of the same header field.
- Increase the range of weights used for multi-path routing from
8 bits to 16 bits.
- Add support for IPv6 PIO p flag in the Prefix Information Option
per draft-ietf-6man-pio-pflag.
- IPv6 IOAM6 support for new tunsrc encap mode for better
performance.
- Detect destinations which blackhole MPTCP traffic and avoid
initiating MPTCP connections to them for a certain period of time,
1h by default.
- Improve IPsec control path performance by removing the inexact
policies list.
- AF_VSOCK: add support for SIOCOUTQ ioctl.
- Add enum for reasons TCP reset was sent for easier tracing.
- Add SMC ringbufs usage statistics.
Drivers:
- Handle netconsole setup failures more gracefully, don't fail
loading, retain the specified target as disabled.
- Extend bonding's IPsec offload pass thru capabilities (ESN, stats).
Filtering:
- Add TCP_BPF_SOCK_OPS_CB_FLAGS to bpf_*sockopt() to address the case
when long-lived sockets miss a chance to set additional callbacks
if a sockops program was not attached early in their lifetime.
- Support using BPF skb helpers in tracepoints.
- Conntrack Netlink: support CTA_FILTER for flush.
- Improve SCTP support in nfnetlink_queue.
- Improve performance of large nftables flush transactions.
Things we sprinkled into general kernel code:
- selftests: support setting an "interpreter" for script files; make
it easy to run as separate cases tests where one "interpreter" is
fed various test descriptions (in our case packet sequences).
Driver API:
- Extend core and ethtool APIs to support many PHYs connected to a
single interface (PHY topologies).
- Extend cable diagnostics to specify whether Time Domain
Reflectometry (TDR) or Active Link Cable Diagnostic (ALCD) was
used.
- Add library for implementing MAC-PHY Ethernet drivers for SPI
devices compatible with Open Alliance 10BASE-T1x MAC-PHY Serial
Interface (TC6) standard.

Alliance standards:
- 1000BaseT1 link settings

SFU since its (first) version 3.0 supports AF_LOCAL sockets and stores them
on filesytem as system file with one zero byte. Add support for detecting
this SFU socket type into cifs_sfu_type() function.

SFU types IntxCHR and IntxBLK are 8 bytes with zero as last byte. Make it
explicit in memcpy and memset calls, so the zero byte is visible in the
code (and not hidden as string trailing nul byte).
It is important for reader to show the last byte for block and char types
because it differs from the last byte of symlink type (which has it 0x01).
Also it is important to show that the type is not nul-term string, but
rather 8 bytes (with some printable bytes).

Currently when sfu mount option is specified then CIFS can recognize SFU
symlink, but is not able to read symlink target location. readlink()
syscall just returns that operation is not supported.
Implement this missing functionality in cifs_sfu_type() function. Read
target location of SFU-style symlink, parse it and fill into fattr's
cf_symlink_target member.
SFU-style symlink is file which has system attribute set and file content
is buffer "IntxLNK\1" (8th byte is 0x01) followed by the target location
encoded in little endian UCS-2/UTF-16. This format was introduced in
Interix 3.0 subsystem, as part of the Microsoft SFU 3.0 and is used also by
all later versions. Previous versions had no symlink support.

- Check data compressibility with some heuristics (copied from
btrfs):
- should_compress() final decision is is_compressible(data)
- Cleanup compress/lz77.h leaving only lz77_compress() exposed:
- Move parts to compress/lz77.c, while removing the rest of it
because they were either unused, used only once, were
implemented wrong (thanks to David Howells for the help)
- Updated the compression parameters (still compatible with
Windows implementation) trading off ~20% compression ratio
for ~40% performance:
- min match len: 3 -> 4
- max distance: 8KiB -> 1KiB
- hash table type: u32 * -> u64 *
Known bugs:
This implementation currently works fine in general, but breaks with
some payloads used during testing. Investigation ongoing, to be
fixed in a next commit.

* Raw NAND changes
The use of for_each_child_of_node_scoped() has been spread into the
subsystem drivers. Aside from that, a couple of exit path have been
fixed (mtk, denali), the TI GPMC bindings have been enhanced to comply
with up-to-date partition descriptions and as always there is a load of
small and misc fixes.
* SPI-NAND changes
The most impacting series this cycle is bringing support for continuous
reads in the SPI-NAND subsystem. This is a feature already merged in the
raw NAND subsystem which allows optimizing the internal fetch times in
the chip while reading sequential pages within an eraseblock. For now
only Macronix NANDs benefit from this feature. While we are talking
about Macronix, some of their chip need an explicit action for selecting
a different plane, and support for it has also been brought.
The bitflip threshold has also been set to the same arbitrary level as
in the raw NAND subsystem to optimize wear leveling decisions, and
finally support for a new Winbond chip has been added.

- New flash support for Zetta ZD25Q128C and Spansion S28HS256T.
- Fix a NULL dereference in probe path for flashes without a name. The
probe path tries to access the name without checking its existence
first. S28HS256T is the first flash to define its entry without a

Pull kvm fix from Paolo Bonzini:
"Do not always honor guest PAT on CPUs that support self-snoop.
This triggers an issue in the bochsdrm driver, which used ioremap()
instead of ioremap_wc() to map the video RAM.
The revert lets video RAM use the WB memory type instead of the slower
UC memory type"
* tag 'for-linus-6.11' of git://git.kernel.org/pub/scm/virt/kvm/kvm:
Revert "KVM: VMX: Always honor guest PAT on CPUs that support self-snoop"
|
|
This reverts commit 377b2f359d1f71c75f8cc352b5c81f2210312d83.
This caused a regression with the bochsdrm driver, which used ioremap()
instead of ioremap_wc() to map the video RAM. After the commit, the
WB memory type is used without the IGNORE_PAT, resulting in the slower
UC memory type. In fact, UC is slow enough to basically cause guests
to not boot... but only on new processors such as Sapphire Rapids and
Cascade Lake. Coffee Lake for example works properly, though that might
also be an effect of being on a larger, more NUMA system.
The driver has been fixed but that does not help older guests. Until we
figure out whether Cascade Lake and newer processors are working as
intended, revert the commit. Long term we might add a quirk, but the
details depend on whether the processors are working as intended: for
example if they are, the quirk might reference bochs-compatible devices,
e.g. in the name and documentation, so that userspace can disable the
quirk by default and only leave it enabled if such a device is being
exposed to the guest.
If instead this is actually a bug in CLX+, then the actions we need to
take are different and depend on the actual cause of the bug.

KVM/arm64 updates for 6.12
* New features:
- Add a Stage-2 page table dumper, reusing the main ptdump
infrastructure, and allowing easier debugging of the our
page-table infrastructure
- Add FP8 support to the KVM/arm64 floating point handling.
- Add NV support for the AT family of instructions, which mostly
results in adding a page table walker that deals with most of the
complexity of the architecture.
* Improvements, fixes and cleanups:
- Add selftest checks for a bunch of timer emulation corner cases
- Fix the multiple of cases where KVM/arm64 doesn't correctly handle
the guest trying to use a GICv3 that isn't advertised
- Remove REG_HIDDEN_USER from the sysreg infrastructure, making
things little more simple
- Prevent MTE tags being restored by userspace if we are actively
logging writes, as that's a recipe for disaster
- Correct the refcount on a page that is not considered for MTE tag
copying (such as a device)
- Relax the synchronisation when walking a page table to split block
mappings, moving it at the end the walk, as there is no need to
perform it on every store.
- Fix boundary check when transfering memory using FFA
- Fix pKVM TLB invalidation, only affecting currently out of tree
code but worth addressing for peace of mind

Introduce HSR offload support for ICSSG
This series introduces HSR offload support for ICSSG driver. To support HSR
offload to hardware, ICSSG HSR firmware is used.
This series introduces,
1. HSR frame offload support for ICSSG driver.
2. HSR Tx Packet duplication offload
3. HSR Tx Tag and Rx Tag offload
4. Multicast filtering support in HSR offload mode.
5. Dependencies related to IEP.

ethtool -K eth2 hsr-tag-rm-offload on
2) Create HSR interface and add slave interfaces to it
ip link add name hsr0 type hsr slave1 eth1 slave2 eth2 \
supervision 45 version 1
3) Add IP address to the HSR interface
ip addr add <IP_ADDR>/24 dev hsr0
4) Bring up the HSR interface
ip link set hsr0 up
Switching back to previous mode:
--------------------------------
1) Delete HSR interface
ip link delete hsr0
2) Disable HSR port-to-port offloading mode, packet duplication
ethtool -K eth1 hsr-fwd-offload off
ethtool -K eth1 hsr-dup-offload off
ethtool -K eth1 hsr-tag-ins-offload off
ethtool -K eth1 hsr-tag-rm-offload off
ethtool -K eth2 hsr-fwd-offload off
ethtool -K eth2 hsr-dup-offload off
ethtool -K eth2 hsr-tag-ins-offload off
ethtool -K eth2 hsr-tag-rm-offload off
Testing the port-to-port frame forward offload feature:
-----------------------------------------------------
1) Connect the LAN cables as shown in the test setup.
2) Configure Station A and Station C in HSR non-offload mode.
3) Configure Station B is HSR offload mode.
4) Since HSR is a redundancy protocol, disconnect cable "Link CA",
to ensure frames from Station A reach Station C only through
Station B.
5) Run iperf3 Server on Station C and client on station A.
7) Check the CPU usage on Station B.
CPU usage report on Station B using mpstat when running UDP iperf3:
-------------------------------------------------------------------
1) Non-Offload case
-------------------
CPU %usr %nice %sys %iowait %irq %soft %steal %guest %idle

2) Offload case

1 0.00 0.00 0.00 0.00 0.00 0.00 0.00 0.00 100.00
Note:
1) At the very least, hsr-fwd-offload must be enabled.
Without offloading the port-to-port offload, other
HSR offloads cannot be enabled.
2) hsr-tag-ins-offload and hsr-dup-offload are tightly coupled in
the firmware implementation. They both need to be enabled / disabled
together.

The HSR stack allows to offload its Tx packet duplication functionality to
the hardware. Enable this offloading feature for ICSSG driver. Add support
to offload HSR Tx Tag Insertion and Rx Tag Removal and duplicate discard.
hsr tag insertion offload and hsr dup offload are tightly coupled in
firmware implementation. Both these features need to be enabled / disabled
together.
Duplicate discard is done as part of RX tag removal and it is
done by the firmware. When driver sends the r30 command
ICSSG_EMAC_HSR_RX_OFFLOAD_ENABLE, firmware does RX tag removal as well as
duplicate discard.

Add support for offloading HSR port-to-port frame forward to hardware.
When the slave interfaces are added to the HSR interface, the PRU cores
will be stopped and ICSSG HSR firmwares will be loaded to them.
Similarly, when HSR interface is deleted, the PRU cores will be
restarted and the last used firmwares will be reloaded. PRUeth
interfaces will be back to the last used mode.
This commit also renames some APIs that are common between switch and
hsr mode with '_fw_offload' suffix.

The def_inc is stored in icss_iep structure. Currently default increment
(ns per clock tick) is hardcoded to 4 (Clock frequency being 250 MHz).
Change this to use the iep->def_inc variable as the iep structure is now
accessible to the driver files.

Fix flash probing by name. Flash entries without a name are allowed
since commit 15eb8303bb42 ("mtd: spi-nor: mark the flash name as
obsolete"). But it was just until recently that a flash entry without a
name was actually introduced. This triggers a bug in the legacy probe by
name path. Skip entries without a name to fix it.

Zetta normally uses BAh as its vendor ID. But for the ZD25Q128C they
took the one from Winbond and messed up the size parameters in SFDP.
Most functions seem compatible with the W25Q128, we just have to fix up
the size.

Writing to the Flash in `sst_nor_write()` is a 3-step process:
first an optional one-byte write to get 2-byte-aligned, then the
bulk of the data is written out in vendor-specific 2-byte writes.
Finally, if there's a byte left over, another one-byte write.
This was implemented 3 times in the body of `sst_nor_write()`.
To reduce code duplication, factor out these sub-steps to their
own function.
