2bca25eaeb spi: Updates for v6.1 
With the exception of some refactoring to fix long standing issues
 where we weren't handling cache syncs properly for messages which had
 PIO and DMA transfers going to the same page correctly there has been o
 work on the core this time around, and it's also been quite a quiet
 release for the drivers too:
 
  - Fix cache syncs for cases where we have DMA and PIO transfers in the
    same message going to the same page.
  - Update the fsl_spi driver to use transfer_one() rather than a custom
    transfer function.
  - Support for configuring transfer speeds with the AMD SPI controller.
  - Support for a second chip select and 64K erase on Intel SPI.
  - Support for Microchip coreQSPI, Nuvoton NPCM845, NXP i.MX93, and
    Rockchip RK3128 and RK3588.

 "With the exception of some refactoring to fix long standing issues
  where we weren't handling cache syncs properly for messages which had
  PIO and DMA transfers going to the same page correctly there has been
  no work on the core this time around, and it's also been quite a quiet
  release for the drivers too:

   - Fix cache syncs for cases where we have DMA and PIO transfers in
     the same message going to the same page

   - Update the fsl_spi driver to use transfer_one() rather than a
     custom transfer function

   - Support for configuring transfer speeds with the AMD SPI controller

   - Support for a second chip select and 64K erase on Intel SPI

   - Support for Microchip coreQSPI, Nuvoton NPCM845, NXP i.MX93, and
     Rockchip RK3128 and RK3588"

d40c874573 regulator: Updates for v6.1 
The core work this time around has mostly been around the code to manage
 regulator modes, simplifying the interface for configuring modes to not
 take account of the voltage and as a side effect resolving a
 bootstrapping issue on systems where we can't read the voltage from the
 regulator.  Otherwise it's been quite a quiet release with some new
 drivers and a devm helper:
 
  - Make the load handling in the Qualcomm RPMH regulators much more
    idiomatic and general cleanups to the handling of load configuration.
  - devm helper for a combined get and enable operation.
  - Support for MediaTek MT6331, Qualcomm PM660, 660L and PM6125, Texas
    Instruments TPS65219.

0326074ff4 Networking changes for 6.1. 
Core
 ----
 
  - Introduce and use a single page frag cache for allocating small skb
    heads, clawing back the 10-20% performance regression in UDP flood
    test from previous fixes.
 
  - Run packets which already went thru HW coalescing thru SW GRO.
    This significantly improves TCP segment coalescing and simplifies
    deployments as different workloads benefit from HW or SW GRO.
 
  - Shrink the size of the base zero-copy send structure.
 
  - Move TCP init under a new slow / sleepable version of DO_ONCE().
 
 BPF
 ---
 
  - Add BPF-specific, any-context-safe memory allocator.
 
  - Add helpers/kfuncs for PKCS#7 signature verification from BPF
    programs.
 
  - Define a new map type and related helpers for user space -> kernel
    communication over a ring buffer (BPF_MAP_TYPE_USER_RINGBUF).
 
  - Allow targeting BPF iterators to loop through resources of one
    task/thread.
 
  - Add ability to call selected destructive functions.
    Expose crash_kexec() to allow BPF to trigger a kernel dump.
    Use CAP_SYS_BOOT check on the loading process to judge permissions.
 
  - Enable BPF to collect custom hierarchical cgroup stats efficiently
    by integrating with the rstat framework.
 
  - Support struct arguments for trampoline based programs.
    Only structs with size <= 16B and x86 are supported.
 
  - Invoke cgroup/connect{4,6} programs for unprivileged ICMP ping
    sockets (instead of just TCP and UDP sockets).
 
  - Add a helper for accessing CLOCK_TAI for time sensitive network
    related programs.
 
  - Support accessing network tunnel metadata's flags.
 
  - Make TCP SYN ACK RTO tunable by BPF programs with TCP Fast Open.
 
  - Add support for writing to Netfilter's nf_conn:mark.
 
 Protocols
 ---------
 
  - WiFi: more Extremely High Throughput (EHT) and Multi-Link
    Operation (MLO) work (802.11be, WiFi 7).
 
  - vsock: improve support for SO_RCVLOWAT.
 
  - SMC: support SO_REUSEPORT.
 
  - Netlink: define and document how to use netlink in a "modern" way.
    Support reporting missing attributes via extended ACK.
 
  - IPSec: support collect metadata mode for xfrm interfaces.
 
  - TCPv6: send consistent autoflowlabel in SYN_RECV state
    and RST packets.
 
  - TCP: introduce optional per-netns connection hash table to allow
    better isolation between namespaces (opt-in, at the cost of memory
    and cache pressure).
 
  - MPTCP: support TCP_FASTOPEN_CONNECT.
 
  - Add NEXT-C-SID support in Segment Routing (SRv6) End behavior.
 
  - Adjust IP_UNICAST_IF sockopt behavior for connected UDP sockets.
 
  - Open vSwitch:
    - Allow specifying ifindex of new interfaces.
    - Allow conntrack and metering in non-initial user namespace.
 
  - TLS: support the Korean ARIA-GCM crypto algorithm.
 
  - Remove DECnet support.
 
 Driver API
 ----------
 
  - Allow selecting the conduit interface used by each port
    in DSA switches, at runtime.
 
  - Ethernet Power Sourcing Equipment and Power Device support.
 
  - Add tc-taprio support for queueMaxSDU parameter, i.e. setting
    per traffic class max frame size for time-based packet schedules.
 
  - Support PHY rate matching - adapting between differing host-side
    and link-side speeds.
 
  - Introduce QUSGMII PHY mode and 1000BASE-KX interface mode.
 
  - Validate OF (device tree) nodes for DSA shared ports; make
    phylink-related properties mandatory on DSA and CPU ports.
    Enforcing more uniformity should allow transitioning to phylink.
 
  - Require that flash component name used during update matches one
    of the components for which version is reported by info_get().
 
  - Remove "weight" argument from driver-facing NAPI API as much
    as possible. It's one of those magic knobs which seemed like
    a good idea at the time but is too indirect to use in practice.
 
  - Support offload of TLS connections with 256 bit keys.
 
 New hardware / drivers
 ----------------------
 
  - Ethernet:
    - Microchip KSZ9896 6-port Gigabit Ethernet Switch
    - Renesas Ethernet AVB (EtherAVB-IF) Gen4 SoCs
    - Analog Devices ADIN1110 and ADIN2111 industrial single pair
      Ethernet (10BASE-T1L) MAC+PHY.
    - Rockchip RV1126 Gigabit Ethernet (a version of stmmac IP).

Pull networking updates from Jakub Kicinski:
 "Core:

   - Introduce and use a single page frag cache for allocating small skb
     heads, clawing back the 10-20% performance regression in UDP flood
     test from previous fixes.

   - Run packets which already went thru HW coalescing thru SW GRO. This
     significantly improves TCP segment coalescing and simplifies
     deployments as different workloads benefit from HW or SW GRO.

   - Shrink the size of the base zero-copy send structure.

   - Move TCP init under a new slow / sleepable version of DO_ONCE().

  BPF:

   - Add BPF-specific, any-context-safe memory allocator.

   - Add helpers/kfuncs for PKCS#7 signature verification from BPF
     programs.

   - Define a new map type and related helpers for user space -> kernel
     communication over a ring buffer (BPF_MAP_TYPE_USER_RINGBUF).

   - Allow targeting BPF iterators to loop through resources of one
     task/thread.

   - Add ability to call selected destructive functions. Expose
     crash_kexec() to allow BPF to trigger a kernel dump. Use
     CAP_SYS_BOOT check on the loading process to judge permissions.

   - Enable BPF to collect custom hierarchical cgroup stats efficiently
     by integrating with the rstat framework.

   - Support struct arguments for trampoline based programs. Only
     structs with size <= 16B and x86 are supported.

   - Invoke cgroup/connect{4,6} programs for unprivileged ICMP ping
     sockets (instead of just TCP and UDP sockets).

   - Add a helper for accessing CLOCK_TAI for time sensitive network
     related programs.

   - Support accessing network tunnel metadata's flags.

   - Make TCP SYN ACK RTO tunable by BPF programs with TCP Fast Open.

   - Add support for writing to Netfilter's nf_conn:mark.

  Protocols:

   - WiFi: more Extremely High Throughput (EHT) and Multi-Link Operation
     (MLO) work (802.11be, WiFi 7).

   - vsock: improve support for SO_RCVLOWAT.

   - SMC: support SO_REUSEPORT.

   - Netlink: define and document how to use netlink in a "modern" way.
     Support reporting missing attributes via extended ACK.

   - IPSec: support collect metadata mode for xfrm interfaces.

   - TCPv6: send consistent autoflowlabel in SYN_RECV state and RST
     packets.

   - TCP: introduce optional per-netns connection hash table to allow
     better isolation between namespaces (opt-in, at the cost of memory
     and cache pressure).

   - MPTCP: support TCP_FASTOPEN_CONNECT.

   - Add NEXT-C-SID support in Segment Routing (SRv6) End behavior.

   - Adjust IP_UNICAST_IF sockopt behavior for connected UDP sockets.

   - Open vSwitch:
      - Allow specifying ifindex of new interfaces.
      - Allow conntrack and metering in non-initial user namespace.

   - TLS: support the Korean ARIA-GCM crypto algorithm.

   - Remove DECnet support.

  Driver API:

   - Allow selecting the conduit interface used by each port in DSA
     switches, at runtime.

   - Ethernet Power Sourcing Equipment and Power Device support.

   - Add tc-taprio support for queueMaxSDU parameter, i.e. setting per
     traffic class max frame size for time-based packet schedules.

   - Support PHY rate matching - adapting between differing host-side
     and link-side speeds.

   - Introduce QUSGMII PHY mode and 1000BASE-KX interface mode.

   - Validate OF (device tree) nodes for DSA shared ports; make
     phylink-related properties mandatory on DSA and CPU ports.
     Enforcing more uniformity should allow transitioning to phylink.

   - Require that flash component name used during update matches one of
     the components for which version is reported by info_get().

   - Remove "weight" argument from driver-facing NAPI API as much as
     possible. It's one of those magic knobs which seemed like a good
     idea at the time but is too indirect to use in practice.

   - Support offload of TLS connections with 256 bit keys.

  New hardware / drivers:

   - Ethernet:
      - Microchip KSZ9896 6-port Gigabit Ethernet Switch
      - Renesas Ethernet AVB (EtherAVB-IF) Gen4 SoCs
      - Analog Devices ADIN1110 and ADIN2111 industrial single pair

Pull audit updates from Paul Moore:
 "Six audit patches for v6.1, most are pretty trivial, but a quick list
  of the highlights are below:

   - Only free the audit proctitle information on task exit. This allows
     us to cache the information and improve performance slightly.

   - Use the time_after() macro to do time comparisons instead of doing
     it directly and potentially causing ourselves problems when the
     timer wraps.

   - Convert an audit_context state comparison from a relative enum
     comparison, e.g. (x < y), to a not-equal comparison to ensure that
     we are not caught out at some unknown point in the future by an
     enum shuffle.

   - A handful of small cleanups such as tidying up comments and
     removing unused declarations"

725737e7c2 STATX_DIOALIGN for 6.1 
Make statx() support reporting direct I/O (DIO) alignment information.
 This provides a generic interface for userspace programs to determine
 whether a file supports DIO, and if so with what alignment restrictions.
 Specifically, STATX_DIOALIGN works on block devices, and on regular
 files when their containing filesystem has implemented support.
 
 An interface like this has been requested for years, since the
 conditions for when DIO is supported in Linux have gotten increasingly
 complex over time.  Today, DIO support and alignment requirements can be
 affected by various filesystem features such as multi-device support,
 data journalling, inline data, encryption, verity, compression,
 checkpoint disabling, log-structured mode, etc.  Further complicating
 things, Linux v6.0 relaxed the traditional rule of DIO needing to be
 aligned to the block device's logical block size; now user buffers (but
 not file offsets) only need to be aligned to the DMA alignment.
 
 The approach of uplifting the XFS specific ioctl XFS_IOC_DIOINFO was
 discarded in favor of creating a clean new interface with statx().

f90497a16e NFSD 6.1 Release Notes 
This release is mostly bug fixes, clean-ups, and optimizations.
 
 One notable set of fixes addresses a subtle buffer overflow issue
 that occurs if a small RPC Call message arrives in an oversized
 RPC record. This is only possible on a framed RPC transport such
 as TCP.
 
 Because NFSD shares the receive and send buffers in one set of
 pages, an oversized RPC record steals pages from the send buffer
 that will be used to construct the RPC Reply message. NFSD must
 not assume that a full-sized buffer is always available to it;
 otherwise, it will walk off the end of the send buffer while
 constructing its reply.
 
 In this release, we also introduce the ability for the server to
 wait a moment for clients to return delegations before it responds
 with NFS4ERR_DELAY. This saves a retransmit and a network round-
 trip when a delegation recall is needed. This work will be built
 upon in future releases.
 
 The NFS server adds another shrinker to its collection. Because
 courtesy clients can linger for quite some time, they might be
 freeable when the server host comes under memory pressure. A new
 shrinker has been added that releases courtesy client resources
 during low memory scenarios.
 
 Lastly, of note: the maximum number of operations per NFSv4
 COMPOUND that NFSD can handle is increased from 16 to 50. There
 are NFSv4 client implementations that need more than 16 to
 successfully perform a mount operation that uses a pathname
 with many components.

 "In this cycle, for container use cases, fscache-based shared domain is
  introduced [1] so that data blobs in the same domain will be storage
  deduplicated and it will also be used for page cache sharing later.

  Also, a special packed inode is now introduced to record inode
  fragments which keep the tail part of files by Yue Hu [2]. You can
  keep arbitary length or (at will) the whole file as a fragment and
  then fragments can be optionally compressed in the packed inode
  together and even deduplicated for smaller image sizes.

  In addition to that, global compressed data deduplication by sharing
  partial-referenced pclusters is also supported in this cycle.

  Summary:

   - Introduce fscache-based domain to share blobs between images

   - Support partial-referenced pclusters for global compressed data

Pull fatfs vfsuid conversion from Christian Brauner:
 "Last cycle we introduced the new vfs{g,u}id_t types that we had agreed
  on. The most important parts of the vfs have been converted but there
  are a few more places we need to switch before we can remove the old
  helpers completely.

  This cycle we converted all filesystems that called idmapped mount
  helpers directly. The affected filesystems are f2fs, fat, fuse, ksmbd,
  overlayfs, and xfs. We've sent patches for all of them. Looking at
  -next f2fs, ksmbd, overlayfs, and xfs have all picked up these patches
  and they should land in mainline during the v6.1 merge window.

  So all filesystems that have a separate tree should send the vfsuid
  conversion themselves. Onle the fat conversion is going through this
  generic fs trees because there is no fat tree.

  In order to change time settings on an inode fat checks that the
  caller either is the owner of the inode or the inode's group is in the
  caller's group list. If fat is on an idmapped mount we compare whether
  the inode mapped into the mount is equivalent to the caller's fsuid.
  If it isn't we compare whether the inode's group mapped into the mount
  is in the caller's group list.

  We now use the new vfsuid based helpers for that"

Pull vfs acl updates from Christian Brauner:
 "These are general fixes and preparatory changes related to the ongoing
  posix acl rework. The actual rework where we build a type safe posix
  acl api wasn't ready for this merge window but we're hopeful for the
  next merge window.

  General fixes:

   - Some filesystems like 9p and cifs have to implement custom posix
     acl handlers because they require access to the dentry in order to
     set and get posix acls while the set and get inode operations
     currently don't. But the ntfs3 filesystem has no such requirement
     and thus implemented custom posix acl xattr handlers when it really
     didn't have to. So this pr contains patch that just implements set
     and get inode operations for ntfs3 and switches it to rely on the
     generic posix acl xattr handlers. (We would've appreciated reviews
     from the ntfs3 maintainers but we didn't get any. But hey, if we
     really broke it we'll fix it. But fstests for ntfs3 said it's
     fine.)

   - The posix_acl_fix_xattr_common() helper has been adapted so it can
     be used by a few more callers and avoiding open-coding the same
     checks over and over.

  Other than the two general fixes this series introduces a new helper
  vfs_set_acl_prepare(). The reason for this helper is so that we can
  mitigate one of the source that change {g,u}id values directly in the
  uapi struct. With the vfs_set_acl_prepare() helper we can move the
  idmapped mount fixup into the generic posix acl set handler.

  The advantage of this is that it allows us to remove the
  posix_acl_setxattr_idmapped_mnt() helper which so far we had to call
  in vfs_setxattr() to account for idmapped mounts. While semantically
  correct the problem with this approach was that we had to keep the
  value parameter of the generic vfs_setxattr() call as non-const. This
  is rectified in this series.

  Ultimately, we will get rid of all the extreme kludges and type
  unsafety once we have merged the posix api - hopefully during the next
  merge window - built solely around get and set inode operations. Which
  incidentally will also improve handling of posix acls in security and
  especially in integrity modesl. While this will come with temporarily
  having two inode operation for posix acls that is nothing compared to
  the problems we have right now and so well worth it. We'll end up with
  something that we can actually reason about instead of needing to
  write novels to explain what's going on"

Merge tag 'lsm-pr-20221003' of git://git.kernel.org/pub/scm/linux/kernel/git/pcmoore/lsm

Pull LSM updates from Paul Moore:
 "Seven patches for the LSM layer and we've got a mix of trivial and
  significant patches. Highlights below, starting with the smaller bits
  first so they don't get lost in the discussion of the larger items:

   - Remove some redundant NULL pointer checks in the common LSM audit
     code.

   - Ratelimit the lockdown LSM's access denial messages.

     With this change there is a chance that the last visible lockdown
     message on the console is outdated/old, but it does help preserve
     the initial series of lockdown denials that started the denial
     message flood and my gut feeling is that these might be the more
     valuable messages.

   - Open userfaultfds as readonly instead of read/write.

     While this code obviously lives outside the LSM, it does have a
     noticeable impact on the LSMs with Ondrej explaining the situation
     in the commit description. It is worth noting that this patch
     languished on the VFS list for over a year without any comments
     (objections or otherwise) so I took the liberty of pulling it into
     the LSM tree after giving fair notice. It has been in linux-next
     since the end of August without any noticeable problems.

   - Add a LSM hook for user namespace creation, with implementations
     for both the BPF LSM and SELinux.

     Even though the changes are fairly small, this is the bulk of the
     diffstat as we are also including BPF LSM selftests for the new
     hook.

     It's also the most contentious of the changes in this pull request
     with Eric Biederman NACK'ing the LSM hook multiple times during its
     development and discussion upstream. While I've never taken NACK's
     lightly, I'm sending these patches to you because it is my belief
     that they are of good quality, satisfy a long-standing need of
     users and distros, and are in keeping with the existing nature of
     the LSM layer and the Linux Kernel as a whole.

     The patches in implement a LSM hook for user namespace creation
     that allows for a granular approach, configurable at runtime, which
     enables both monitoring and control of user namespaces. The general
     consensus has been that this is far preferable to the other
     solutions that have been adopted downstream including outright
     removal from the kernel, disabling via system wide sysctls, or
     various other out-of-tree mechanisms that users have been forced to
     adopt since we haven't been able to provide them an upstream
     solution for their requests. Eric has been steadfast in his
     objections to this LSM hook, explaining that any restrictions on
     the user namespace could have significant impact on userspace.
     While there is the possibility of impacting userspace, it is
     important to note that this solution only impacts userspace when it
     is requested based on the runtime configuration supplied by the
     distro/admin/user. Frederick (the pathset author), the LSM/security
     community, and myself have tried to work with Eric during
     development of this patchset to find a mutually acceptable
     solution, but Eric's approach and unwillingness to engage in a
     meaningful way have made this impossible. I have CC'd Eric directly
     on this pull request so he has a chance to provide his side of the
     story; there have been no objections outside of Eric's"

Pull SELinux updates from Paul Moore:
 "Six SELinux patches, all are simple and easily understood, but a list
  of the highlights is below:

   - Use 'grep -E' instead of 'egrep' in the SELinux policy install
     script.

     Fun fact, this seems to be GregKH's *second* dedicated SELinux
     patch since we transitioned to git (ignoring merges, the SPDX
     stuff, and a trivial fs reference removal when lustre was yanked);
     the first was back in 2011 when selinuxfs was placed in
     /sys/fs/selinux. Oh, the memories ...

   - Convert the SELinux policy boolean values to use signed integer
     types throughout the SELinux kernel code.

     Prior to this we were using a mix of signed and unsigned integers
     which was probably okay in this particular case, but it is
     definitely not a good idea in general.

   - Remove a reference to the SELinux runtime disable functionality in
     /etc/selinux/config as we are in the process of deprecating that.

     See [1] for more background on this if you missed the previous
     notes on the deprecation.

18ff0bcda6 ethtool: add interface to interact with Ethernet Power Equipment 
Add interface to support Power Sourcing Equipment. At current step it
provides generic way to address all variants of PSE devices as defined
in IEEE 802.3-2018 but support only objects specified for IEEE 802.3-2018 104.4
PoDL Power Sourcing Equipment (PSE).

Currently supported and mandatory objects are:
IEEE 802.3-2018 30.15.1.1.3 aPoDLPSEPowerDetectionStatus
IEEE 802.3-2018 30.15.1.1.2 aPoDLPSEAdminState
IEEE 802.3-2018 30.15.1.2.1 acPoDLPSEAdminControl

This is minimal interface needed to control PSE on each separate
ethernet port but it provides not all mandatory objects specified in
IEEE 802.3-2018.

Since "PoDL PSE" and "PSE" have similar names, but some different values
I decide to not merge them and keep separate naming schema. This should
allow as to be as close to IEEE 802.3 spec as possible and avoid name
conflicts in the future.

This implementation is connected to PHYs instead of MACs because PSE
auto classification can potentially interfere with PHY auto negotiation.
So, may be some extra PHY related initialization will be needed.

With WIP version of ethtools interaction with PSE capable link looks
as following:

$ ip l
...
5: t1l1@eth0: <BROADCAST,MULTICAST> ..

3114b075eb net: add framework to support Ethernet PSE and PDs devices 
This framework was create with intention to provide support for Ethernet PSE
(Power Sourcing Equipment) and PDs (Powered Device).

At current step this patch implements generic PSE support for PoDL (Power over
Data Lines 802.3bu) specification with reserving name space for PD devices as
well.

This framework can be extended to support 802.3af and 802.3at "Power via the
Media Dependent Interface" (or PoE/Power over Ethernet)
