Here is the big set of USB and Thunderbolt changes for 5.18-rc1.
Nothing major in here, just lots of little improvements and cleanups and
new device support. Highlights are:
- list iterator fixups for when we walk past the end of the list
(a common problem that was cut/pasted in almost all USB gadget
drivers)
- xen USB driver "hardening" for malicious hosts
- xhci driver updates and fixes for more hardware types
- xhci debug cable fixes to make it actually work again
- usb gadget audio driver improvements
- usb gadget storage fixes to work with OS-X
- lots of other small usb gadget fixes and updates
- USB DWC3 driver improvements for more hardware types
- Lots of other small USB driver improvements
- DTS updates for some USB platforms
Note, the DTS updates will have a merge conflict in your tree. The
fixup should be simple, but if not, I can provide a merged tree if
needed.
All of these have been in linux-next for a while with no reported
issues.

This reverts commit aa6f8dcbab.
It turns out this breaks at least the ath9k wireless driver, and
possibly others.
What the ath9k driver does on packet receive is to set up the DMA
transfer with:
int ath_rx_init(..)
..
bf->bf_buf_addr = dma_map_single(sc->dev, skb->data,
common->rx_bufsize,
DMA_FROM_DEVICE);
and then the receive logic (through ath_rx_tasklet()) will fetch
incoming packets
static bool ath_edma_get_buffers(..)
..
dma_sync_single_for_cpu(sc->dev, bf->bf_buf_addr,
common->rx_bufsize, DMA_FROM_DEVICE);
ret = ath9k_hw_process_rxdesc_edma(ah, rs, skb->data);
if (ret == -EINPROGRESS) {
/*let device gain the buffer again*/
dma_sync_single_for_device(sc->dev, bf->bf_buf_addr,
common->rx_bufsize, DMA_FROM_DEVICE);
return false;
}
and it's worth noting how that first DMA sync:
dma_sync_single_for_cpu(..DMA_FROM_DEVICE);
is there to make sure the CPU can read the DMA buffer (possibly by
copying it from the bounce buffer area, or by doing some cache flush).
The iommu correctly turns that into a "copy from bounce bufer" so that
the driver can look at the state of the packets.
In the meantime, the device may continue to write to the DMA buffer, but
we at least have a snapshot of the state due to that first DMA sync.
But that _second_ DMA sync:
dma_sync_single_for_device(..DMA_FROM_DEVICE);
is telling the DMA mapping that the CPU wasn't interested in the area
because the packet wasn't there. In the case of a DMA bounce buffer,
that is a no-op.
Note how it's not a sync for the CPU (the "for_device()" part), and it's
not a sync for data written by the CPU (the "DMA_FROM_DEVICE" part).
Or rather, it _should_ be a no-op. That's what commit aa6f8dcbab
broke: it made the code bounce the buffer unconditionally, and changed
the DMA_FROM_DEVICE to just unconditionally and illogically be
DMA_TO_DEVICE.
[ Side note: purely within the confines of the swiotlb driver it wasn't
entirely illogical: The reason it did that odd DMA_FROM_DEVICE ->
DMA_TO_DEVICE conversion thing is because inside the swiotlb driver,
it uses just a swiotlb_bounce() helper that doesn't care about the
whole distinction of who the sync is for - only which direction to
bounce.
So it took the "sync for device" to mean that the CPU must have been
the one writing, and thought it meant DMA_TO_DEVICE. ]
Also note how the commentary in that commit was wrong, probably due to
that whole confusion, claiming that the commit makes the swiotlb code
"bounce unconditionally (that is, also
when dir == DMA_TO_DEVICE) in order do avoid synchronising back stale
data from the swiotlb buffer"
which is nonsensical for two reasons:
- that "also when dir == DMA_TO_DEVICE" is nonsensical, as that was
exactly when it always did - and should do - the bounce.
- since this is a sync for the device (not for the CPU), we're clearly
fundamentally not coping back stale data from the bounce buffers at
all, because we'd be copying *to* the bounce buffers.
So that commit was just very confused. It confused the direction of the
synchronization (to the device, not the cpu) with the direction of the
DMA (from the device).

it's a bit odd that this text is duplicate. So, this patch just clean

Linus pointed out the benefits of C99 some years ago, especially variable
declarations in loops [1]. At that time, we were not ready for the
migration due to old compilers.
Recently, Jakob Koschel reported a bug in list_for_each_entry(), which
leaks the invalid pointer out of the loop [2]. In the discussion, we
agreed that the time had come. Now that GCC 5.1 is the minimum compiler
version, there is nothing to prevent us from going to -std=gnu99, or even
straight to -std=gnu11.
Discussions for a better list iterator implementation are ongoing, but
this patch set must land first.

If CONFIG_RANDOM_TRUST_CPU is set, the RNG initializes using RDRAND.
But, the user can disable (or enable) this behavior by setting
`random.trust_cpu=0/1` on the kernel command line. This allows system
builders to do reasonable things while avoiding howls from tinfoil
hatters. (Or vice versa.)
CONFIG_RANDOM_TRUST_BOOTLOADER is basically the same thing, but regards
the seed passed via EFI or device tree, which might come from RDRAND or
a TPM or somewhere else. In order to allow distros to more easily enable
this while avoiding those same howls (or vice versa), this commit adds
the corresponding `random.trust_bootloader=0/1` toggle.

AS_HAS_LSE_ATOMICS as of commit 2decad92f4 ("arm64: mte: Ensure
TIF_MTE_ASYNC_FAULT is set atomically"), which requires Clang 12.

- Explicitly say that the "Shadow memory" section is only applicable to
software KASAN modes.
- Mention that shadow-based KASAN_VMALLOC is supported on arm64.

When viewing page owner information, we may want to cull blocks of
information with our own rules. So it is important to enhance culling
function to provide the support for customizing culling rules.
Therefore, following adjustments are made:
1. Add --cull option to support the culling of blocks of information
with user-defined culling rules.
./page_owner_sort <input> <output> --cull=<rules>
./page_owner_sort <input> <output> --cull <rules>
<rules> is a single argument in the form of a comma-separated list to
specify individual culling rules, by the sequence of keys k1,k2, ....
Mixed use of abbreviated and complete-form of keys is allowed.
For reference, please see the document(Documentation/vm/page_owner.rst).
Now, assuming two blocks in the input file are as follows:
Page allocated via order 0, mask xxxx, pid 1, tgid 1 (task_name_demo)
PFN xxxx
prep_new_page+0xd0/0xf8
get_page_from_freelist+0x4a0/0x1290
__alloc_pages+0x168/0x340
alloc_pages+0xb0/0x158
Page allocated via order 0, mask xxxx, pid 32, tgid 32 (task_name_demo)
PFN xxxx
prep_new_page+0xd0/0xf8
get_page_from_freelist+0x4a0/0x1290
__alloc_pages+0x168/0x340
alloc_pages+0xb0/0x158
If we want to cull the blocks by stacktrace and task command name, we can
use this command:
./page_owner_sort <input> <output> --cull=stacktrace,name
The output would be like:
2 times, 2 pages, task_comm_name: task_name_demo
prep_new_page+0xd0/0xf8
get_page_from_freelist+0x4a0/0x1290
__alloc_pages+0x168/0x340
alloc_pages+0xb0/0x158
As we can see, these two blocks are culled successfully, for they share
the same pid and task command name.
However, if we want to cull the blocks by pid, stacktrace and task command
name, we can this command:
./page_owner_sort <input> <output> --cull=stacktrace,name,pid
The output would be like:
1 times, 1 pages, PID 1, task_comm_name: task_name_demo
prep_new_page+0xd0/0xf8
get_page_from_freelist+0x4a0/0x1290
__alloc_pages+0x168/0x340
alloc_pages+0xb0/0x158
1 times, 1 pages, PID 32, task_comm_name: task_name_demo
prep_new_page+0xd0/0xf8
get_page_from_freelist+0x4a0/0x1290
__alloc_pages+0x168/0x340
alloc_pages+0xb0/0x158
As we can see, these two blocks are failed to cull, for their PIDs are
different.
2. Add explanations of --cull options to the document.

When viewing page owner information, we may also need to select the blocks
by PID, TGID or task command name, which helps to get more accurate page
allocation information as needed.
Therefore, following adjustments are made:
1. Add three new options, including --pid, --tgid and --name, to support
the selection of information blocks by a specific pid, tgid and task
command name. In addtion, multiple options are allowed to be used at
the same time.
./page_owner_sort [input] [output] --pid <PID>
./page_owner_sort [input] [output] --tgid <TGID>
./page_owner_sort [input] [output] --name <TASK_COMMAND_NAME>
Assuming a scenario when a multi-threaded program, ./demo (PID =
5280), is running, and ./demo creates a child process (PID = 5281).
$ps
PID TTY TIME CMD
5215 pts/0 00:00:00 bash
5280 pts/0 00:00:00 ./demo
5281 pts/0 00:00:00 ./demo
5282 pts/0 00:00:00 ps
It would be better to filter out the records with tgid=5280 and the
task name "demo" when debugging the parent process, and the specific
usage is
./page_owner_sort [input] [output] --tgid 5280 --name demo
2. Add explanations of three new options, including --pid, --tgid and
--name, to the document.

As a result, the following adjustments have been made:
1. Add a new -P option to sort the information of blocks by TGID in

2. Adjust the order of member variables in block_list strust to avoid

This is more foundational infrastructure in preparation for dynamic

Core
----
- Introduce XDP multi-buffer support, allowing the use of XDP with
jumbo frame MTUs and combination with Rx coalescing offloads (LRO).
- Speed up netns dismantling (5x) and lower the memory cost a little.
Remove unnecessary per-netns sockets. Scope some lists to a netns.
Cut down RCU syncing. Use batch methods. Allow netdev registration
to complete out of order.
- Support distinguishing timestamp types (ingress vs egress) and
maintaining them across packet scrubbing points (e.g. redirect).
- Continue the work of annotating packet drop reasons throughout
the stack.
- Switch netdev error counters from an atomic to dynamically
allocated per-CPU counters.
- Rework a few preempt_disable(), local_irq_save() and busy waiting
sections problematic on PREEMPT_RT.
- Extend the ref_tracker to allow catching use-after-free bugs.
BPF
---
- Introduce "packing allocator" for BPF JIT images. JITed code is
marked read only, and used to be allocated at page granularity.
Custom allocator allows for more efficient memory use, lower
iTLB pressure and prevents identity mapping huge pages from
getting split.
- Make use of BTF type annotations (e.g. __user, __percpu) to enforce
the correct probe read access method, add appropriate helpers.
- Convert the BPF preload to use light skeleton and drop
the user-mode-driver dependency.
- Allow XDP BPF_PROG_RUN test infra to send real packets, enabling
its use as a packet generator.
- Allow local storage memory to be allocated with GFP_KERNEL if called
from a hook allowed to sleep.
- Introduce fprobe (multi kprobe) to speed up mass attachment (arch
bits to come later).
- Add unstable conntrack lookup helpers for BPF by using the BPF
kfunc infra.
- Allow cgroup BPF progs to return custom errors to user space.
- Add support for AF_UNIX iterator batching.
- Allow iterator programs to use sleepable helpers.
- Support JIT of add, and, or, xor and xchg atomic ops on arm64.
- Add BTFGen support to bpftool which allows to use CO-RE in kernels
without BTF info.
- Large number of libbpf API improvements, cleanups and deprecations.
Protocols
---------
- Micro-optimize UDPv6 Tx, gaining up to 5% in test on dummy netdev.
- Adjust TSO packet sizes based on min_rtt, allowing very low latency
links (data centers) to always send full-sized TSO super-frames.
- Make IPv6 flow label changes (AKA hash rethink) more configurable,
via sysctl and setsockopt. Distinguish between server and client
behavior.
- VxLAN support to "collect metadata" devices to terminate only
configured VNIs. This is similar to VLAN filtering in the bridge.
- Support inserting IPv6 IOAM information to a fraction of frames.
- Add protocol attribute to IP addresses to allow identifying where
given address comes from (kernel-generated, DHCP etc.)
- Support setting socket and IPv6 options via cmsg on ping6 sockets.
- Reject mis-use of ECN bits in IP headers as part of DSCP/TOS.
Define dscp_t and stop taking ECN bits into account in fib-rules.
- Add support for locked bridge ports (for 802.1X).
- tun: support NAPI for packets received from batched XDP buffs,
doubling the performance in some scenarios.
- IPv6 extension header handling in Open vSwitch.
- Support IPv6 control message load balancing in bonding, prevent
neighbor solicitation and advertisement from using the wrong port.
Support NS/NA monitor selection similar to existing ARP monitor.
- SMC
- improve performance with TCP_CORK and sendfile()
- support auto-corking
- support TCP_NODELAY
- MCTP (Management Component Transport Protocol)
- add user space tag control interface
- I2C binding driver (as specified by DMTF DSP0237)
- Multi-BSSID beacon handling in AP mode for WiFi.
- Bluetooth:
- handle MSFT Monitor Device Event
- add MGMT Adv Monitor Device Found/Lost events
- Multi-Path TCP:
- add support for the SO_SNDTIMEO socket option
- lots of selftest cleanups and improvements
- Increase the max PDU size in CAN ISOTP to 64 kB.
Driver API
----------
- Add HW counters for SW netdevs, a mechanism for devices which
offload packet forwarding to report packet statistics back to
software interfaces such as tunnels.
- Select the default NIC queue count as a fraction of number of
physical CPU cores, instead of hard-coding to 8.
- Expose devlink instance locks to drivers. Allow device layer of
drivers to use that lock directly instead of creating their own
which always runs into ordering issues in devlink callbacks.
- Add header/data split indication to guide user space enabling
of TCP zero-copy Rx.
- Allow configuring completion queue event size.
- Refactor page_pool to enable fragmenting after allocation.
- Add allocation and page reuse statistics to page_pool.
- Improve Multiple Spanning Trees support in the bridge to allow
reuse of topologies across VLANs, saving HW resources in switches.
- DSA (Distributed Switch Architecture):
- replay and offload of host VLAN entries
- offload of static and local FDB entries on LAG interfaces
- FDB isolation and unicast filtering

Driver API
----------
- Add HW counters for SW netdevs, a mechanism for devices which
offload packet forwarding to report packet statistics back to
software interfaces such as tunnels.
- Select the default NIC queue count as a fraction of number of
physical CPU cores, instead of hard-coding to 8.
- Expose devlink instance locks to drivers. Allow device layer of
drivers to use that lock directly instead of creating their own
which always runs into ordering issues in devlink callbacks.
- Add header/data split indication to guide user space enabling of
TCP zero-copy Rx.
- Allow configuring completion queue event size.
- Refactor page_pool to enable fragmenting after allocation.
- Add allocation and page reuse statistics to page_pool.
- Improve Multiple Spanning Trees support in the bridge to allow
reuse of topologies across VLANs, saving HW resources in switches.
- DSA (Distributed Switch Architecture):
- replay and offload of host VLAN entries
- offload of static and local FDB entries on LAG interfaces
- FDB isolation and unicast filtering

The panic_print setting allows users to collect more information in a
panic event, like memory stats, tasks, CPUs backtraces, etc. This is an
interesting debug mechanism, but currently the print event happens *after*
kmsg_dump(), meaning that pstore, for example, cannot collect a dmesg with
the panic_print extra information.
This patch changes that in 2 steps:
(a) The panic_print setting allows to replay the existing kernel log
buffer to the console (bit 5), besides the extra information dump.
This functionality makes sense only at the end of the panic()
function. So, we hereby allow to distinguish the two situations by a
new boolean parameter in the function panic_print_sys_info().
(b) With the above change, we can safely call panic_print_sys_info()
before kmsg_dump(), allowing to dump the extra information when using
pstore or other kmsg dumpers.
The additional messages from panic_print could overwrite the oldest
messages when the buffer is full. The only reasonable solution is to use
a large enough log buffer, hence we added an advice into the kernel
parameters documentation about that.

Currently the "panic_print" parameter/sysctl allows some interesting debug
information to be printed during a panic event. This is useful for
example in cases the user cannot kdump due to resource limits, or if the
user collects panic logs in a serial output (or pstore) and prefers a fast
reboot instead of a kdump.
Happens that currently there's no way to see all CPUs backtraces in a
panic using "panic_print" on architectures that support that. We do have
"oops_all_cpu_backtrace" sysctl, but although partially overlapping in the
functionality, they are orthogonal in nature: "panic_print" is a panic
tuning (and we have panics without oopses, like direct calls to panic() or
maybe other paths that don't go through oops_enter() function), and the
original purpose of "oops_all_cpu_backtrace" is to provide more
information on oopses for cases in which the users desire to continue
running the kernel even after an oops, i.e., used in non-panic scenarios.
So, we hereby introduce an additional bit for "panic_print" to allow
dumping the CPUs backtraces during a panic event.

Patch series "Some improvements on panic_print".
This is a mix of a documentation fix with some additions to the
"panic_print" syscall / parameter. The goal here is being able to collect
all CPUs backtraces during a panic event and also to enable "panic_print"
in a kdump event - details of the reasoning and design choices in the
patches.
This patch (of 3):
Commit de6da1e8bc ("panic: add an option to replay all the printk
message in buffer") added a new bit to the sysctl/kernel parameter
"panic_print", but the documentation was added only in
kernel-parameters.txt, not in the sysctl guide.
Fix it here by adding bit 5 to sysctl admin-guide documentation.

After a somewhat quiet 5.17 release, the size of the DT changes
is a bit larger again. There are nine new SoC that get added,
all of them related to existing platforms:

over the place: Samsung, Renesas, Mstar, wpcm450, OMAP, AT91, Allwinner,
i.MX, Tegra, Aspeed, Oxnas, Qualcomm, Mediatek, and Broadcom.
Samsung has a rework for its pinctrl schema that is a bit tricky and
requires driver changes to be included here.
A few more platforms only have smaller cleanups and DT Schema fixes,
this includes SoCFPGA, ux500, ixp4xx, STi, Xilinx Zynq, LG, and Juno.
The new machines are really too many to list, but I'll do it anyway:

- OSMC Vero 4K+ (Amlogic S905D)
Arm Juno
- Separate DT depending on SCMI firmware version
Aspeed:
- Quanta S6Q BMC (AST2600)
- ASRock ROMED8HM3 (AST2500)
Broadcom:
- Raspberry Pi Zero 2 W

Pull ARM devicetree updates from Arnd Bergmann:
"After a somewhat quiet 5.17 release, the size of the DT changes is a
bit larger again. There are nine new SoC that get added, all of them
related to existing platforms:
- Airoha (formerly Mediatek/EcoNet) EN7523 networking SoC and EVB
- Mediatek mt6582 tablet platform with the Prestigio PMT5008 3G
tablet
- Microchip Lan966 networking SoC and it evaluation board
- Qualcomm Snapdragon 625/632 midrange phone SoCs, with the LG Nexus
5X and Fairphone FP3 phones

with their evaluation boards
- Samsung Exynos 850 phone SoC and reference board
- Samsung Exynos7885 with the Samsung Galaxy A8 (2018) phone
- Tesla FSD (Fully Self-Driving), an automotive SoC loosely derived
from the Samsung Exynos family.
- TI K3/AM62 SoC and reference board
Support for additional functionality in existing dts files is added
all over the place: Samsung, Renesas, Mstar, wpcm450, OMAP, AT91,
Allwinner, i.MX, Tegra, Aspeed, Oxnas, Qualcomm, Mediatek, and
Broadcom.
Samsung has a rework for its pinctrl schema that is a bit tricky and
requires driver changes to be included here.
A few more platforms only have smaller cleanups and DT Schema fixes,
this includes SoCFPGA, ux500, ixp4xx, STi, Xilinx Zynq, LG, and Juno.
The new machines are really too many to list, but I'll do it anyway:
Allwinner:
- A20-Marsboard development board

on OPTEE and support for atomic operations.
- Cleanups to the TEE subsystem, refactoring its memory management
For SoC specific drivers without a separate subsystem, changes include
- Smaller updates and fixes for TI, AT91/SAMA5, Qualcomm and NXP
Layerscape SoCs.

There are three sets of updates for 5.18 in the asm-generic tree:
- The set_fs()/get_fs() infrastructure gets removed for good. This
was already gone from all major architectures, but now we can
finally remove it everywhere, which loses some particularly
tricky and error-prone code.
There is a small merge conflict against a parisc cleanup, the
solution is to use their new version.
- The nds32 architecture ends its tenure in the Linux kernel. The
hardware is still used and the code is in reasonable shape, but
the mainline port is not actively maintained any more, as all
remaining users are thought to run vendor kernels that would never
be updated to a future release.
There are some obvious conflicts against changes to the removed
files.
- A series from Masahiro Yamada cleans up some of the uapi header
files to pass the compile-time checks.

A recent change added a warning when yamllint is not installed, as it is
needed for 'make dt_binding_check'. However, it also changed
DT_SCHEMA_LINT to be a simple make variable, which is evaluated when a
Makefile is evaluated. This causes a warning when running 'make clean',
as Documentation/devicetree/bindings/Makefile has a "clean-files"
variable:
$ make -s clean
which: no yamllint in (...)
warning: python package 'yamllint' not installed, skipping
Make DT_SCHEMA_LINT a recursive variable so it is evaluated only when it
is used. The warning still triggers when 'make dt_binding_check' is run.

U-Boot uses environment variables for storing device setup data. It
usually needs to be accessed by a bootloader, kernel and often
user-space.
This binding allows describing environment data located in a raw flash
partition. It's treated as NVMEM device and can be reused later for
other storage devices.
Using DT should be cleaner than hardcoding & duplicating such info in
multiple places. Bootloader & kernel can share DTS and user-space can
try reading it too or just have correct data exposed by a kernel.
A custom "compatible" string allows system to automatically load
relevant NVMEM driver but phandle can be also used for reading raw
location.

ALSA core fixes, most notably for covering PCM ioctl races, but the
most of rest are device-specific changes.
Below are some highlights:
ALSA core:
- Fixes for PCM ioctl races that may lead to UAF
- Fix for oversized allocations in PCM OSS layer
ASoC:
- Start of moving SoF to support multiple IPC mechanisms
- Use of NHLT ACPI table to reduce the amount of quirking required
for Intel systems
- Preliminary works forthcoming Intel AVS driver for legacy Intel DSP
firmwares
- Support for AMD PDM, Atmel PDMC, Awinic AW8738, i.MX cards with
TLV320AIC31xx, Intel machines with CS35L41 and ESSX8336, Mediatek
MT8181 wideband bluetooth, nVidia Tegra234, Qualcomm SC7280,
Renesas RZ/V2L, Texas Instruments TAS585M
HD-audio:
- Driver re-binding fix for HD-audio
- Updates for Intel ADL and Tegra234, various platform quirks for
Dell, HP, Lenovo, ASUS, Samsung and Clevo machines
USB-audio:
- Quirk updates for Scarlett2, RODE, Corsair devices"

atmel,at91sam9-rtc is a confusing name for this file as it is documenting

- New user_events interface. User space can register an event with the kernel
describing the format of the event. Then it will receive a byte in a page
mapping that it can check against. A privileged task can then enable that
event like any other event, which will change the mapped byte to true,
telling the user space application to start writing the event to the
tracing buffer.
- Add new "ftrace_boot_snapshot" kernel command line parameter. When set,
the tracing buffer will be saved in the snapshot buffer at boot up when
the kernel hands things over to user space. This will keep the traces that
happened at boot up available even if user space boot up has tracing as
well.
- Have TRACE_EVENT_ENUM() also update trace event field type descriptions.
Thus if a static array defines its size with an enum, the user space trace
event parsers can still know how to parse that array.
- Add new TRACE_CUSTOM_EVENT() macro. This acts the same as the
TRACE_EVENT() macro, but will attach to an existing tracepoint. This will
make one tracepoint be able to trace different content and not be stuck at
only what the original TRACE_EVENT() macro exports.
- Fixes to tracing error logging.
- Better saving of cmdlines to PIDs when tracing (use the wakeup events for
mapping).

This patch (of 3):
DAMON code calls the low level monitoring primitives implementations the
monitoring operations. The documentation would have no problem at still
calling those primitives implementation because there is no real
difference in the concepts, but making it more consistent with the code
would make it better. This commit therefore convert sentences in the doc
specifically pointing the implementations of the primitives to call it

Allow the use of a deferrable timer, which does not force CPU wake-ups
when the system is idle. A consequence is that the sample interval
becomes very unpredictable, to the point that it is not guaranteed that
the KFENCE KUnit test still passes.
Nevertheless, on power-constrained systems this may be preferable, so
let's give the user the option should they accept the above trade-off.

Zswap has an ability to efficiently store same-value filled pages, which
can be turned on and off using the "same_filled_pages_enabled"
parameter.
However, there is currently no way to enable just this (lightweight)
functionality, while not making use of the whole compressed page storage
machinery.
Add a "non_same_filled_pages_enabled" parameter which allows disabling
handling of pages that aren't same-value filled. This way zswap can be
run in such lightweight same-value filled pages only mode.

With the advent of various new memory types, some machines will have
multiple types of memory, e.g. DRAM and PMEM (persistent memory). The
memory subsystem of these machines can be called memory tiering system,
because the performance of the different types of memory are usually
different.
In such system, because of the memory accessing pattern changing etc,
some pages in the slow memory may become hot globally. So in this
patch, the NUMA balancing mechanism is enhanced to optimize the page
placement among the different memory types according to hot/cold
dynamically.
In a typical memory tiering system, there are CPUs, fast memory and slow
memory in each physical NUMA node. The CPUs and the fast memory will be
put in one logical node (called fast memory node), while the slow memory
will be put in another (faked) logical node (called slow memory node).
That is, the fast memory is regarded as local while the slow memory is
regarded as remote. So it's possible for the recently accessed pages in
the slow memory node to be promoted to the fast memory node via the
existing NUMA balancing mechanism.
The original NUMA balancing mechanism will stop to migrate pages if the
free memory of the target node becomes below the high watermark. This
is a reasonable policy if there's only one memory type. But this makes
the original NUMA balancing mechanism almost do not work to optimize
page placement among different memory types. Details are as follows.
It's the common cases that the working-set size of the workload is
larger than the size of the fast memory nodes. Otherwise, it's
unnecessary to use the slow memory at all. So, there are almost always
no enough free pages in the fast memory nodes, so that the globally hot
pages in the slow memory node cannot be promoted to the fast memory
node. To solve the issue, we have 2 choices as follows,
a. Ignore the free pages watermark checking when promoting hot pages
from the slow memory node to the fast memory node. This will
create some memory pressure in the fast memory node, thus trigger
the memory reclaiming. So that, the cold pages in the fast memory
node will be demoted to the slow memory node.
b. Define a new watermark called wmark_promo which is higher than
wmark_high, and have kswapd reclaiming pages until free pages reach
such watermark. The scenario is as follows: when we want to promote
hot-pages from a slow memory to a fast memory, but fast memory's free
pages would go lower than high watermark with such promotion, we wake
up kswapd with wmark_promo watermark in order to demote cold pages and
free us up some space. So, next time we want to promote hot-pages we
might have a chance of doing so.
The choice "a" may create high memory pressure in the fast memory node.
If the memory pressure of the workload is high, the memory pressure
may become so high that the memory allocation latency of the workload
is influenced, e.g. the direct reclaiming may be triggered.
The choice "b" works much better at this aspect. If the memory
pressure of the workload is high, the hot pages promotion will stop
earlier because its allocation watermark is higher than that of the
normal memory allocation. So in this patch, choice "b" is implemented.
A new zone watermark (WMARK_PROMO) is added. Which is larger than the
high watermark and can be controlled via watermark_scale_factor.
In addition to the original page placement optimization among sockets,
the NUMA balancing mechanism is extended to be used to optimize page
placement according to hot/cold among different memory types. So the
sysctl user space interface (numa_balancing) is extended in a backward
compatible way as follow, so that the users can enable/disable these
functionality individually.
The sysctl is converted from a Boolean value to a bits field. The
definition of the flags is,
- 0: NUMA_BALANCING_DISABLED
- 1: NUMA_BALANCING_NORMAL
- 2: NUMA_BALANCING_MEMORY_TIERING
We have tested the patch with the pmbench memory accessing benchmark
with the 80:20 read/write ratio and the Gauss access address
distribution on a 2 socket Intel server with Optane DC Persistent
Memory Model. The test results shows that the pmbench score can
improve up to 95.9%.
Thanks Andrew Morton to help fix the document format error.

Patch series "Free the 2nd vmemmap page associated with each HugeTLB
page", v7.
This series can minimize the overhead of struct page for 2MB HugeTLB
pages significantly. It further reduces the overhead of struct page by
12.5% for a 2MB HugeTLB compared to the previous approach, which means
2GB per 1TB HugeTLB. It is a nice gain. Comments and reviews are
welcome. Thanks.
The main implementation and details can refer to the commit log of patch
1. In this series, I have changed the following four helpers, the
following table shows the impact of the overhead of those helpers.
+------------------+-----------------------+
| APIs | head page | tail page |
+------------------+-----------+-----------+
| PageHead() | Y | N |
+------------------+-----------+-----------+
| PageTail() | Y | N |
+------------------+-----------+-----------+
| PageCompound() | N | N |
+------------------+-----------+-----------+
| compound_head() | Y | N |
+------------------+-----------+-----------+
Y: Overhead is increased.
N: Overhead is _NOT_ increased.
It shows that the overhead of those helpers on a tail page don't change
between "hugetlb_free_vmemmap=on" and "hugetlb_free_vmemmap=off". But the
overhead on a head page will be increased when "hugetlb_free_vmemmap=on"
(except PageCompound()). So I believe that Matthew Wilcox's folio series
will help with this.
The users of PageHead() and PageTail() are much less than compound_head()
and most users of PageTail() are VM_BUG_ON(), so I have done some tests
about the overhead of compound_head() on head pages.
I have tested the overhead of calling compound_head() on a head page,
which is 2.11ns (Measure the call time of 10 million times
compound_head(), and then average).
For a head page whose address is not aligned with PAGE_SIZE or a
non-compound page, the overhead of compound_head() is 2.54ns which is
increased by 20%. For a head page whose address is aligned with
PAGE_SIZE, the overhead of compound_head() is 2.97ns which is increased by
40%. Most pages are the former. I do not think the overhead is
significant since the overhead of compound_head() itself is low.
This patch (of 5):
This patch minimizes the overhead of struct page for 2MB HugeTLB pages
significantly. It further reduces the overhead of struct page by 12.5%
for a 2MB HugeTLB compared to the previous approach, which means 2GB per
1TB HugeTLB (2MB type).
After the feature of "Free sonme vmemmap pages of HugeTLB page" is
enabled, the mapping of the vmemmap addresses associated with a 2MB
HugeTLB page becomes the figure below.
HugeTLB struct pages(8 pages) page frame(8 pages)
+-----------+ ---virt_to_page---> +-----------+ mapping to +-----------+---> PG_head
| | | 0 | -------------> | 0 |
| | +-----------+ +-----------+
| | | 1 | -------------> | 1 |
| | +-----------+ +-----------+
| | | 2 | ----------------^ ^ ^ ^ ^ ^
| | +-----------+ | | | | |
| | | 3 | ------------------+ | | | |
| | +-----------+ | | | |
| | | 4 | --------------------+ | | |
| 2MB | +-----------+ | | |
| | | 5 | ----------------------+ | |
| | +-----------+ | |
| | | 6 | ------------------------+ |
| | +-----------+ |
| | | 7 | --------------------------+
| | +-----------+
| |
| |
| |
+-----------+
As we can see, the 2nd vmemmap page frame (indexed by 1) is reused and
remaped. However, the 2nd vmemmap page frame is also can be freed to
the buddy allocator, then we can change the mapping from the figure
above to the figure below.
HugeTLB struct pages(8 pages) page frame(8 pages)
+-----------+ ---virt_to_page---> +-----------+ mapping to +-----------+---> PG_head
| | | 0 | -------------> | 0 |
| | +-----------+ +-----------+
| | | 1 | ---------------^ ^ ^ ^ ^ ^ ^
| | +-----------+ | | | | | |
| | | 2 | -----------------+ | | | | |
| | +-----------+ | | | | |
| | | 3 | -------------------+ | | | |
| | +-----------+ | | | |
| | | 4 | ---------------------+ | | |
| 2MB | +-----------+ | | |
| | | 5 | -----------------------+ | |
| | +-----------+ | |
| | | 6 | -------------------------+ |
| | +-----------+ |
| | | 7 | ---------------------------+
| | +-----------+
| |
| |
| |
+-----------+
After we do this, all tail vmemmap pages (1-7) are mapped to the head
vmemmap page frame (0). In other words, there are more than one page
struct with PG_head associated with each HugeTLB page. We __know__ that
there is only one head page struct, the tail page structs with PG_head are
fake head page structs. We need an approach to distinguish between those
two different types of page structs so that compound_head(), PageHead()
and PageTail() can work properly if the parameter is the tail page struct
but with PG_head.
The following code snippet describes how to distinguish between real and
fake head page struct.
if (test_bit(PG_head, &page->flags)) {
unsigned long head = READ_ONCE(page[1].compound_head);
if (head & 1) {
if (head == (unsigned long)page + 1)
==> head page struct
else
==> tail page struct
} else
==> head page struct
}
We can safely access the field of the @page[1] with PG_head because the
@page is a compound page composed with at least two contiguous pages.

The allocated inode cache is supposed to be added to its memcg list_lru
which should be allocated as well in advance. That can be done by
kmem_cache_alloc_lru() which allocates object and list_lru. The file
systems is main user of it. So introduce alloc_inode_sb() to allocate
file system specific inodes and set up the inode reclaim context
properly. The file system is supposed to use alloc_inode_sb() to
allocate inodes.
In later patches, we will convert all users to the new API.

During the integration of PREEMPT_RT support, the code flow around
memcg_check_events() resulted in `twisted code'. Moving the code around
and avoiding then would then lead to an additional local-irq-save
section within memcg_check_events(). While looking better, it adds a
local-irq-save section to code flow which is usually within an
local-irq-off block on non-PREEMPT_RT configurations.
The threshold event handler is a deprecated memcg v1 feature. Instead
of trying to get it to work under PREEMPT_RT just disable it. There
should be no users on PREEMPT_RT. From that perspective it makes even
less sense to get it to work under PREEMPT_RT while having zero users.
Make memory.soft_limit_in_bytes and cgroup.event_control return
-EOPNOTSUPP on PREEMPT_RT. Make an empty memcg_check_events() and
memcg_write_event_control() which return only -EOPNOTSUPP on PREEMPT_RT.
Document that the two knobs are disabled on PREEMPT_RT.

Currently memcg stats show several types of kernel memory: kernel stack,
page tables, sock, vmalloc, and slab. However, there are other
allocations with __GFP_ACCOUNT (or supersets such as GFP_KERNEL_ACCOUNT)
that are not accounted in any of those stats, a few examples are:
- various kvm allocations (e.g. allocated pages to create vcpus)
- io_uring
- tmp_page in pipes during pipe_write()
- bpf ringbuffers
- unix sockets
Keeping track of the total kernel memory is essential for the ease of
migration from cgroup v1 to v2 as there are large discrepancies between
v1's kmem.usage_in_bytes and the sum of the available kernel memory
stats in v2. Adding separate memcg stats for all __GFP_ACCOUNT kernel
allocations is an impractical maintenance burden as there a lot of those
all over the kernel code, with more use cases likely to show up in the
future.
Therefore, add a "kernel" memcg stat that is analogous to kmem page
counter, with added benefits such as using rstat infrastructure which
aggregates stats more efficiently. Additionally, this provides a
lighter alternative in case the legacy kmem is deprecated in the future

Add some "big-picture" documentation for read-ahead and polish the code
to make it fit this documentation.
The meaning of ->async_size is clarified to match its name. i.e. Any
request to ->readahead() has a sync part and an async part. The caller
will wait for the sync pages to complete, but will not wait for the
async pages. The first async page is still marked PG_readahead
Note that the current function names page_cache_sync_ra() and
page_cache_async_ra() are misleading. All ra request are partly sync
and partly async, so either part can be empty. A page_cache_sync_ra()
request will usually set ->async_size non-zero, implying it is not all
synchronous.
When a non-zero req_count is passed to page_cache_async_ra(), the
implication is that some prefix of the request is synchronous, though
the calculation made there is incorrect - I haven't tried to fix it.

In this cycle, f2fs has some performance improvements for Android workloads such
as using read-unfair rwsems and adding some sysfs entries to control GCs and
discard commands in more details. In addtiion, it has some tunings to improve
the recovery speed after sudden power-cut.
Enhancement:
- add reader-unfair rwsems with F2FS_UNFAIR_RWSEM
: will replace with generic API support
- adjust to make the readahead/recovery flow more efficiently
- sysfs entries to control issue speeds of GCs and Discard commands
- enable idmapped mounts
Bug fix:
- correct wrong error handling routines
- fix missing conditions in quota
- fix a potential deadlock between writeback and block plug routines
- fix a deadlock btween freezefs and evict_inode
We've added some boundary checks to avoid kernel panics on corrupted images,
and several minor code clean-ups.

Pull selinux updates from Paul Moore:
"We've got a number of SELinux patches queued up, the highlights are:
- Fixup the security_fs_context_parse_param() LSM hook so it executes
all of the LSM hook implementations unless a serious error occurs.
We also correct the SELinux hook implementation so that it returns
zero on success.
- In addition to a few SELinux mount option parsing fixes, we
simplified the parsing by moving it earlier in the process.
The logic was that it was unlikely an admin/user would use the new
mount API and not have the policy loaded before passing the SELinux
options.
- Properly fixed the LSM/SELinux/SCTP hooks with the addition of the
security_sctp_assoc_established() hook.
This work was done in conjunction with the netdev folks and should
complete the move of the SCTP labeling from the endpoints to the
associations.
- Fixed a variety of sparse warnings caused by changes in the "__rcu"
markings of some core kernel structures.
- Ensure we access the superblock's LSM security blob using the
stacking-safe accessors.
- Added the ability for the kernel to always allow FIOCLEX and
FIONCLEX if the "ioctl_skip_cloexec" policy capability is
specified.
- Various constifications improvements, type casting improvements,
additional return value checks, and dead code/parameter removal.
- Documentation fixes"

Kleine-König which changes the return type of the remove() function to
void as part of some wider work he's doing to do this for all bus types,
causing updates to most SPI device drivers. The branch with that on has
been cross merged with a couple of other trees which added new SPI
drivers this cycle, I'm not expecting any build issues resulting from

This series improves perf support for RISC-V based system using SBI PMU
and Sscofpmf extensions, by adding a new generic RISC-V perf framework
along with a pair of drivers: one that usese the new
performance-monitoring extensions and one that keeps support for the
existing systems that only have the legacy counters.
Tested-by: Nikita Shubin <n.shubin@yadro.com>
* palmer/riscv-pmu:
MAINTAINERS: Add entry for RISC-V PMU drivers
Documentation: riscv: Remove the old documentation
RISC-V: Add sscofpmf extension support
RISC-V: Add perf platform driver based on SBI PMU extension
RISC-V: Add RISC-V SBI PMU extension definitions
RISC-V: Add a simple platform driver for RISC-V legacy perf
RISC-V: Add a perf core library for pmu drivers
RISC-V: Add CSR encodings for all HPMCOUNTERS
RISC-V: Remove the current perf implementation
The existing pmu documentation describes the limitation of perf
infrastructure in RISC-V ISA and limited feature set of perf in RISC-V.
However, SBI PMU extension and sscofpmf extension(ISA extension) allows to
implement most of the required features of perf. Remove the old
documentation which is not accurate anymore.

Merge tag 'random-5.18-rc1-for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/crng/random
Pull random number generator updates from Jason Donenfeld:
"There have been a few important changes to the RNG's crypto, but the
intent for 5.18 has been to shore up the existing design as much as
possible with modern cryptographic functions and proven constructions,
rather than actually changing up anything fundamental to the RNG's
design.
So it's still the same old RNG at its core as before: it still counts
entropy bits, and collects from the various sources with the same
heuristics as before, and so forth. However, the cryptographic
algorithms that transform that entropic data into safe random numbers
have been modernized.
Just as important, if not more, is that the code has been cleaned up
and re-documented. As one of the first drivers in Linux, going back to
1.3.30, its general style and organization was showing its age and
becoming both a maintenance burden and an auditability impediment.
Hopefully this provides a more solid foundation to build on for the
future. I encourage you to open up the file in full, and maybe you'll
remark, "oh, that's what it's doing," and enjoy reading it. That, at
least, is the eventual goal, which this pull begins working toward.
Here's a summary of the various patches in this pull:
- /dev/urandom and /dev/random now do the same thing, per the patch
we discussed on the list. I think this is worth trying out. If it
does appear problematic, I've made sure to keep it standalone and
revertible without any conflicts.
- Fixes and cleanups for numerous integer type problems, locking
issues, and general code quality concerns.
- The input pool's LFSR has been replaced with a cryptographically
secure hash function, which has security and performance benefits
alike, and consequently allows us to count entropy bits linearly.
- The pre-init injection now uses a real hash function too, instead
of an LFSR or vanilla xor.
- The interrupt handler's fast_mix() function now uses one round of
SipHash, rather than the fake crypto that was there before.
- All additions of RDRAND and RDSEED now go through the input pool's
hash function, in part to mitigate ridiculous hypothetical CPU
backdoors, but more so to have a consistent interface for ingesting
entropy that's easy to analyze, making everything happen one way,
instead of a potpourri of different ways.
- The crng now works on per-cpu data, while also being in accordance
with the actual "fast key erasure RNG" design. This allows us to
fix several boot-time race complications associated with the prior
dynamically allocated model, eliminates much locking, and makes our
backtrack protection more robust.
- Batched entropy now erases doled out values so that it's backtrack
resistant.
- Working closely with Sebastian, the interrupt handler no longer
needs to take any locks at all, as we punt the
synchronized/expensive operations to a workqueue. This is
especially nice for PREEMPT_RT, where taking spinlocks in irq
context is problematic. It also makes the handler faster for the
rest of us.
- Also working with Sebastian, we now do the right thing on CPU
hotplug, so that we don't use stale entropy or fail to accumulate
new entropy when CPUs come back online.
- We handle virtual machines that fork / clone / snapshot, using the
"vmgenid" ACPI specification for retrieving a unique new RNG seed,
which we can use to also make WireGuard (and in the future, other
things) safe across VM forks.
- Around boot time, we now try to reseed more often if enough entropy
is available, before settling on the usual 5 minute schedule.
- Last, but certainly not least, the documentation in the file has
been updated considerably"

Pull power management updates from Rafael Wysocki:
"These are mostly fixes and cleanups all over the code and a new piece
of documentation for Intel uncore frequency scaling.
Functionality-wise, the intel_idle driver will support Sapphire Rapids
Xeons natively now (with some extra facilities for controlling
C-states more precisely on those systems), virtual guests will take
the ACPI S4 hardware signature into account by default, the
intel_pstate driver will take the defualt EPP value from the firmware,
cpupower utility will support the AMD P-state driver added in the
previous cycle, and there is a new tracer utility for that driver.
Specifics:
- Allow device_pm_check_callbacks() to be called from interrupt
context without issues (Dmitry Baryshkov).
- Modify devm_pm_runtime_enable() to automatically handle
pm_runtime_dont_use_autosuspend() at driver exit time (Douglas
Anderson).
- Make the schedutil cpufreq governor use to_gov_attr_set() instead
of open coding it (Kevin Hao).
- Replace acpi_bus_get_device() with acpi_fetch_acpi_dev() in the
cpufreq longhaul driver (Rafael Wysocki).
- Unify show() and store() naming in cpufreq and make it use
__ATTR_XX (Lianjie Zhang).
- Make the intel_pstate driver use the EPP value set by the firmware
by default (Srinivas Pandruvada).
- Re-order the init checks in the powernow-k8 cpufreq driver (Mario
Limonciello).
- Make the ACPI processor idle driver check for architectural support
for LPI to avoid using it on x86 by mistake (Mario Limonciello).
- Add Sapphire Rapids Xeon support to the intel_idle driver (Artem
Bityutskiy).
- Add 'preferred_cstates' module argument to the intel_idle driver to
work around C1 and C1E handling issue on Sapphire Rapids (Artem
Bityutskiy).
- Add core C6 optimization on Sapphire Rapids to the intel_idle
driver (Artem Bityutskiy).
- Optimize the haltpoll cpuidle driver a bit (Li RongQing).
- Remove leftover text from intel_idle() kerneldoc comment and fix up
white space in intel_idle (Rafael Wysocki).
- Fix load_image_and_restore() error path (Ye Bin).
- Fix typos in comments in the system wakeup hadling code (Tom Rix).
- Clean up non-kernel-doc comments in hibernation code (Jiapeng
Chong).
- Fix __setup handler error handling in system-wide suspend and
hibernation core code (Randy Dunlap).
- Add device name to suspend_report_result() (Youngjin Jang).
- Make virtual guests honour ACPI S4 hardware signature by default
(David Woodhouse).
- Block power off of a parent PM domain unless child is in deepest
state (Ulf Hansson).
- Use dev_err_probe() to simplify error handling for generic PM
domains (Ahmad Fatoum).
- Fix sleep-in-atomic bug caused by genpd_debug_remove() (Shawn Guo).
- Document Intel uncore frequency scaling (Srinivas Pandruvada).
- Add DTPM hierarchy description (Daniel Lezcano).
- Change the locking scheme in DTPM (Daniel Lezcano).
- Fix dtpm_cpu cleanup at exit time and missing virtual DTPM pointer
release (Daniel Lezcano).
- Make dtpm_node_callback[] static (kernel test robot).
- Fix spelling mistake "initialze" -> "initialize" in
dtpm_create_hierarchy() (Colin Ian King).
- Add tracer tool for the amd-pstate driver (Jinzhou Su).
- Fix PC6 displaying in turbostat on some systems (Artem Bityutskiy).
- Add AMD P-State support to the cpupower utility (Huang Rui)"

Pull ACPI updates from Rafael Wysocki:
"From the new functionality perspective, the most significant items
here are the new driver for the 'ARM Generic Diagnostic Dump and
Reset' device, the extension of fine grain fan control in the ACPI fan
driver, and the change making it possible to use CPPC information to
obtain CPU capacity.
There are also a few new quirks, a bunch of fixes, including the
platform-level _OSC handling change to make it actually take the
platform firmware response into account, some code and documentation
cleanups, and a notable update of the ACPI device enumeration
documentation.

Move compound_pincount from the third page to the second page, which
means it's available for all compound pages. That lets us delete
hpage_pincount_available().
On 32-bit systems, there isn't enough space for both compound_pincount
and compound_nr in the second page (it would collide with page->private,
which is in use for pages in the swap cache), so revert the optimisation
of storing both compound_order and compound_nr on 32-bit systems.

KVM_CAP_DISABLE_QUIRKS is irrevocably broken. The capability does not
advertise the set of quirks which may be disabled to userspace, so it is
impossible to predict the behavior of KVM. Worse yet,
KVM_CAP_DISABLE_QUIRKS will tolerate any value for cap->args[0], meaning
it fails to reject attempts to set invalid quirk bits.
The only valid workaround for the quirky quirks API is to add a new CAP.
Actually advertise the set of quirks that can be disabled to userspace
so it can predict KVM's behavior. Reject values for cap->args[0] that
contain invalid bits.
Finally, add documentation for the new capability and describe the
existing quirks.

'virtio,mmio' devices are always coherent within a guest. As Arm DTs
are default non-coherent, the 'dma-coherent' property needs to be set on
the virtio device to mark them as such. This aligns with the QEMU 'virt'

The CSR GSD4t is a CSR product using the SiRFstarIV core, and
the CSR CSRG05TA03-ICJE-R is a CSR product using the SiRFstarV
core.
These chips have a SRESETN line that can be pulled low to hard
reset the chip and in some designs this is connected to a GPIO,
so add this as an optional property.
Update the example with a reset line so users see that it need
to be tagged as active low.

In recent times, the review cycle for stable releases have been changed.
In particular, there is release candidate phase between ACKing patches
and new stable release. Also, in case of failed submissions (fail to
apply to stable tree), manual backport (Option 3) have to be submitted
instead.
Update the release cycle documentation on stable-kernel-rules.rst to
reflect the above.

Add property to set DSP domain as non-secure.
ADSP/MDSP/SDSP are by default secured, where as CDSP can be either be
secured/unsecured.
non-secured Compute DSP would allow users to load unsigned process
and run hexagon instructions, but limiting access to secured hardware
within the DSP.
Based on this flag device nodes for secured and unsecured are created.
