Linus Torvalds 64edfa6506 Merge tag 'net-deletions' of git://git.kernel.org/pub/scm/linux/kernel/git/netdev/net-next
Pull networking deletions from Jakub Kicinski:
 "Delete some obsolete networking code

  Old code like amateur radio and NFC have long been a burden to core
  networking developers. syzbot loves to find bugs in BKL-era code, and
  noobs try to fix them.

  If we want to have a fighting chance of surviving the LLM-pocalypse
  this code needs to find a dedicated owner or get deleted. We've talked
  about these deletions multiple times in the past and every time
  someone wanted the code to stay. It is never very clear to me how many
  of those people actually use the code vs are just nostalgic to see it
  go. Amateur radio did have occasional users (or so I think) but most
  users switched to user space implementations since its all super slow
  stuff. Nobody stepped up to maintain the kernel code.

  We were lucky enough to find someone who wants to help with NFC so
  we're giving that a chance. Let's try to put the rest of this code
  behind us"

Jakub Kicinski 4f10f1dfb2 net: remove ISDN subsystem and Bluetooth CMTP
Remove the ISDN (mISDN, CAPI) subsystem and Bluetooth CMTP protocol
from the kernel tree.

ISDN is a pretty old technology and it's unclear whether anyone still
uses it. I went over the last few years of git history and all the
commits are either tree-wide conversions or syzbot/static analyzer
fixes.

When we discussed removal in the past IIRC there were some concerns
about ISDN still being used in parts of Germany. Unfortunately, the
code base is quite old, none of the current maintainers are familiar
with it and AI tools will have a field day finding bugs here.

Delete this code and preserve it in an out-of-tree repository
for any remaining users:
https://github.com/linux-netdev/mod-orphan

UAPI constants AF_ISDN/PF_ISDN and the SELinux isdn_socket class
are preserved for ABI stability, but the rest of uAPI is removed.

Pratyush Yadav (Google)andAndrew Morton 320c7234d1 MAINTAINERS: update KHO and LIVE UPDATE maintainers
Patch series "MAINTAINERS: update KHO and LIVE UPDATE entries".

This series contains some updates for the Kexec Handover (KHO) and Live
update entries.  Patch 1 updates the maintainers list and adds the
liveupdate tree.  Patches 2 and 3 clean up stale files in the list.


This patch (of 3):

I have been helping out with reviewing and developing KHO.  I would also
like to help maintain it.  Change my entry from R to M for KHO and live
update.  Alex has been inactive for a while, so to avoid over-crowding the
KHO entry and to keep the information up-to-date, move his entry from M to
R.

We also now have a tree for KHO and live update at liveupdate/linux.git
where we plan to start maintaining those subsystems and start queuing the
patches.  List that in the entries as well.

Linus Torvalds cdd4dc3aeb Merge tag 'ntfs-for-7.1-rc1-v2' of git://git.kernel.org/pub/scm/linux/kernel/git/linkinjeon/ntfs
Pull ntfs resurrection from Namjae Jeon:
 "Ever since Kari Argillander’s 2022 report [1] regarding the state of
  the ntfs3 driver, I have spent the last 4 years working to provide
  full write support and current trends (iomap, no buffer head, folio),
  enhanced performance, stable maintenance, utility support including
  fsck for NTFS in Linux.

  This new implementation is built upon the clean foundation of the
  original read-only NTFS driver, adding:

   - Write support:

     Implemented full write support based on the classic read-only NTFS
     driver. Added delayed allocation to improve write performance
     through multi-cluster allocation and reduced fragmentation of the
     cluster bitmap.

   - iomap conversion:

     Switched buffered IO (reads/writes), direct IO, file extent
     mapping, readpages, and writepages to use iomap.

   - Remove buffer_head:

     Completely removed buffer_head usage by converting to folios. As a
     result, the dependency on CONFIG_BUFFER_HEAD has been removed from
     Kconfig.

   - Stability improvements:

     The new ntfs driver passes 326 xfstests, compared to 273 for ntfs3.
     All tests passed by ntfs3 are a complete subset of the tests passed
     by this implementation. Added support for fallocate, idmapped
     mounts, permissions, and more.

  xfstests Results report:

     Total tests run: 787
     Passed         : 326
     Failed         : 38
     Skipped        : 423

  Failed tests breakdown:
    - 34 tests require metadata journaling
    - 4 other tests:
         094: No unwritten extent concept in NTFS on-disk format
         563: cgroup v2 aware writeback accounting not supported
         631: RENAME_WHITEOUT support required
         787: NFS delegation test"

 - "pid: make sub-init creation retryable" (Oleg Nesterov)

   Several cleanups and fixups to the hardlockup detector code and its
   documentation

 - "lib/bch: fix undefined behavior from signed left-shifts" (Josh Law)

   A couple of small/theoretical fixes in the bch code

 - "ocfs2/dlm: fix two bugs in dlm_match_regions()" (Junrui Luo)

 - "cleanup the RAID5 XOR library" (Christoph Hellwig)

   A quite far-reaching cleanup to this code. I can't do better than to
   quote Christoph:

     "The XOR library used for the RAID5 parity is a bit of a mess right
      now. The main file sits in crypto/ despite not being cryptography
      and not using the crypto API, with the generic implementations
      sitting in include/asm-generic and the arch implementations
      sitting in an asm/ header in theory. The latter doesn't work for
      many cases, so architectures often build the code directly into
      the core kernel, or create another module for the architecture
      code.

      Change this to a single module in lib/ that also contains the
      architecture optimizations, similar to the library work Eric
      Biggers has done for the CRC and crypto libraries later. After
      that it changes to better calling conventions that allow for
      smarter architecture implementations (although none is contained
      here yet), and uses static_call to avoid indirection function call
      overhead"

 - "lib/list_sort: Clean up list_sort() scheduling workarounds"
   (Kuan-Wei Chiu)

   Clean up this library code by removing a hacky thing which was added
   for UBIFS, which UBIFS doesn't actually need

 - "Fix bugs in extract_iter_to_sg()" (Christian Ehrhardt)

   Fix a few bugs in the scatterlist code, add in-kernel tests for the
   now-fixed bugs and fix a leak in the test itself

 - "kdump: Enable LUKS-encrypted dump target support in ARM64 and
   PowerPC" (Coiby Xu)

   Enable support of the LUKS-encrypted device dump target on arm64 and
   powerpc

This reverts commit 7ffa8f3d30.

Reverts the removal of the classic read-only ntfs driver to
serve as the base for a new read-write ntfs implementation.
If we stack changes on top of the revert patch, It will significantly
reduce the diff size, making the review easier.

This revert intentionally excludes the restoration of Kconfig and
Makefile. The Kconfig and Makefile will be added back in the final patch
of this series, enabling the driver only after all features and
improvements have been applied.

     make the right choice when inlining code, to avoid unneeded calls
     for small helper and stack canary overhead in the fast-path.

     This generates better and faster code with very small or no text
     size increases, as in many cases the call generated more code than
     the actual inlined helper.

   - Extend AccECN implementation so that is now functionally complete,
     also allow the user-space enabling it on a per network namespace
     basis.

   - Add support for memory providers with large (above 4K) rx buffer.
     Paired with hw-gro, larger rx buffer sizes reduce the number of
     buffers traversing the stack, dincreasing single stream CPU usage
     by up to ~30%.

   - Do not add HBH header to Big TCP GSO packets. This simplifies the
     RX path, the TX path and the NIC drivers, and is possible because
     user-space taps can now interpret correctly such packets without
     the HBH hint.

   - Allow IPv6 routes to be configured with a gateway address that is
     resolved out of a different interface than the one specified,
     aligning IPv6 to IPv4 behavior.

   - Multi-queue aware sch_cake. This makes it possible to scale the
     rate shaper of sch_cake across multiple CPUs, while still enforcing
     a single global rate on the interface.

   - Add support for the nbcon (new buffer console) infrastructure to
     netconsole, enabling lock-free, priority-based console operations
     that are safer in crash scenarios.

   - Improve the TCP ipv6 output path to cache the flow information,
     saving cpu cycles, reducing cache line misses and stack use.

   - Improve netfilter packet tracker to resolve clashes for most
     protocols, avoiding unneeded drops on rare occasions.

   - Add IP6IP6 tunneling acceleration to the flowtable infrastructure.

   - Reduce tcp socket size by one cache line.

   - Notify neighbour changes atomically, avoiding inconsistencies
     between the notification sequence and the actual states sequence.

   - Add vsock namespace support, allowing complete isolation of vsocks
     across different network namespaces.

   - Improve xsk generic performances with cache-alignment-oriented
     optimizations.

   - Support netconsole automatic target recovery, allowing netconsole
     to reestablish targets when underlying low-level interface comes
     back online.

  Driver API:

   - Support for switching the working mode (automatic vs manual) of a
     DPLL device via netlink.

   - Introduce PHY ports representation to expose multiple front-facing
     media ports over a single MAC.

   - Introduce "rx-polarity" and "tx-polarity" device tree properties,
     to generalize polarity inversion requirements for differential
     signaling.

   - Add helper to create, prepare and enable managed clocks.

  Device drivers:

   - Add Huawei hinic3 PF etherner driver.

   - Add DWMAC glue driver for Motorcomm YT6801 PCIe ethernet
     controller.

   - Add ethernet driver for MaxLinear MxL862xx switches

   - Remove parallel-port Ethernet driver.

   - Convert existing driver timestamp configuration reporting to
     hwtstamp_get and remove legacy ioctl().

   - Convert existing drivers to .get_rx_ring_count(), simplifing the RX
     ring count retrieval. Also remove the legacy fallback path.

Ethan Nelson-MooreandBorislav Petkov (AMD) 1795dc528c EDAC/r82600: Remove this obsolete driver
This driver supports the Radisys 82600 embedded chipset, which was used with
Pentium III-era CPUs. It is highly unlikely that it is still used.  Besides
its own documentation, the only information I was able to find about the
R82600, after looking through many pages of Google results, was that it was
used in a Nokia 2G GSM base station.

The original author said:

"This was after Bluesmoke (watch was out-of-tree), and was pay of the first
set of in tree edac drivers (a fresh design as far as I remember).

This particular driver did apparently get used by Akamai quite heavily and
widely  but all ancient history now. The Radisys r82600 edac driver 
r82600_edac.c was closely related hardware from the same era, and can probably
go too (although being embedded hardware, it's possible its production
lifespan was considerably longer).

Tim."

Ethan Nelson-MooreandBorislav Petkov (AMD) 83b314e9c8 EDAC/i82443bxgx: Remove driver that has been marked broken since 2007
The history of this driver is pretty amusing. It was marked broken in
2007 in

  28f96eeafc ("drivers/edac-new-i82443bxgz-mc-driver: mark as broken").

It was then fixed in 2008 in

  53a2fe5804 ("edac: make i82443bxgx_edac coexist with intel_agp"),

but the dependency on BROKEN was never removed. Given that this was never
fixed in the last ~18 years, it is obvious there is no demand for this driver.
Remove it and move the former maintainer to the CREDITS file.

Ethan Nelson-MooreandJakub Kicinski aba0138eb7 net: ethernet: neterion: s2io: remove unused driver
The s2io driver supports Exar (formerly Neterion and S2io) PCI-X 10
Gigabit Ethernet cards. Hardware supporting PCI-X has not been
manufactured in years. On x86, it was quickly replaced by PCIe. While
it stuck around longer on POWER hardware, the last POWER hardware to
support it was POWER7, which is not supported by ppc64le Linux
distributions. The last supported mainstream ppc64 Linux distribution
was RHEL 7; while it is still supported under ELS, ELS is only
available for x86 and IBM Z. It is possible to use many PCI-X cards in
standard PCI slots (which are still available on new motherboards), but
it does not make sense to do so for 10 Gigabit Ethernet because the
maximum bandwidth of standard PCI is only 1067 Mbps. It is therefore
highly unlikely that this driver is still being used. Remove the
driver, and move the former maintainer to the CREDITS file (restoring
credit for the vxge driver, which was removed in commit f05643a0f6
("eth: remove neterion/vxge").

HIPPI has not been relevant for over two decades. It was rapidly
eclipsed by Fibre Channel, and even when it was new, it was

NFC stack in Linux is in poor shape, with several bugs being discovered
