Linus Torvalds a436a0b847 Various clean ups and bug fixes in ext4 for 7.1:
* Refactor code paths involved with partial block zero-out in
     prearation for converting ext4 to use iomap for buffered writes.
   * Remove use of d_alloc() from ext4 in preparation for the deprecation
     of this interface.
   * Replace some J_ASSERTS with a journal abort so we can avoid a kernel
     panic for a localized file system error
   * Simplify various code paths in mballoc, move_extent, and fast commit
   * Fix rare deadlock in jbd2_journal_cancel_revoke() that can be
     triggered by generic/013 when blocksize < pagesize.
   * Fix memory leak when releasing an extended attribute when its
     value is stored in an ea_inode
   * Fix various potential kunit test bugs in fs/ext4/extents.c
   * Fix potential out-of-bounds access in check_xattr() with a corrupted
     file system
   * Make the jbd2_inode dirty range tracking safe for lockless reads
   * Avoid a WARN_ON when writeback files due to a corrupted file system;
     we already print an ext4 warning indicatign that data will be lost,
     so the WARN_ON is not necessary and doesn't add any new information

Linus Torvalds cdd4dc3aeb Major changes:
- 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

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.

     mapping, readpages, and writepages to use iomap.

Linus Torvalds cb30bf881c tracing updates for v7.1:
- Fix printf format warning for bprintf
 
   sunrpc uses a trace_printk() that triggers a printf warning during the
   compile. Move the __printf() attribute around for when debugging is not
   enabled the warning will go away.
 
 - Remove redundant check for EVENT_FILE_FL_FREED in event_filter_write()
 
   The FREED flag is checked in the call to event_file_file() and then
   checked again right afterward, which is unneeded.
 
 - Clean up event_file_file() and event_file_data() helpers
 
   These helper functions played a different role in the past, but now with
   eventfs, the READ_ONCE() isn't needed. Simplify the code a bit and also
   add a warning to event_file_data() if the file or its data is not present.
 
 - Remove updating file->private_data in tracing open
 
   All access to the file private data is handled by the helper functions,
   which do not use file->private_data. Stop updating it on open.
 
 - Show ENUM names in function arguments via BTF in function tracing
 
   When showing the function arguments when func-args option is set for
   function tracing, if one of the arguments is found to be an enum, show the
   name of the enum instead of its number.
 
 - Add new trace_call__##name() API for tracepoints
 
   Tracepoints are enabled via static_branch() blocks, where when not
   enabled, there's only a nop that is in the code where the execution will
   just skip over it. When tracing is enabled, the nop is converted to a
   direct jump to the tracepoint code. Sometimes more calculations are
   required to be performed to update the parameters of the tracepoint. In
   this case, trace_##name##_enabled() is called which is a static_branch()
   that gets enabled only when the tracepoint is enabled. This allows the
   extra calculations to also be skipped by the nop:
 
   if (trace_foo_enabled()) {
       x = bar();
       trace_foo(x);
   }
 
   Where the x=bar() is only performed when foo is enabled. The problem with
   this approach is that there's now two static_branch() calls. One for
   checking if the tracepoint is enabled, and then again to know if the
   tracepoint should be called. The second one is redundant.
 
   Introduce trace_call__foo() that will call the foo() tracepoint directly
   without doing a static_branch():
 
   if (trace_foo_enabled()) {
       x = bar();
       trace_call__foo();
   }
 
 - Update various locations to use the new trace_call__##name() API
 
 - Move snapshot code out of trace.c
 
   Cleaning up trace.c to not be a "dump all", move the snapshot code out of
   it and into a new trace_snapshot.c file.
 
 - Clean up some "%*.s" to "%*s"
 
 - Allow boot kernel command line options to be called multiple times
 
   Have options like:
 
     ftrace_filter=foo ftrace_filter=bar ftrace_filter=zoo
 
   Equal to:
 
     ftrace_filter=foo,bar,zoo
 
 - Fix ipi_raise event CPU field to be a CPU field
 
   The ipi_raise target_cpus field is defined as a __bitmask(). There is now a
   __cpumask() field definition. Update the field to use that.
 
 - Have hist_field_name() use a snprintf() and not a series of strcat()
 
   It's safer to use snprintf() that a series of strcat().
 
 - Fix tracepoint regfunc balancing
 
   A tracepoint can define a "reg" and "unreg" function that gets called
   before the tracepoint is enabled, and after it is disabled respectively.
   But on error, after the "reg" func is called and the tracepoint is not
   enabled, the "unreg" function is not called to tear down what the "reg"
   function performed.
 
 - Fix output that shows what histograms are enabled
 
   Event variables are displayed incorrectly in the histogram output.
 
   Instead of "sched.sched_wakeup.$var", it is showing
   "$sched.sched_wakeup.var" where the '$' is in the incorrect location.
 
 - Some other simple cleanups.

     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.
 
 - The 2 patch series "lib/list_sort: Clean up list_sort() scheduling
   workarounds" from Kuan-Wei Chiu cleans up this library code by removing
   a hacky thing which was added for UBIFS, which UBIFS doesn't actually
   need.
 
 - The 5 patch series "Fix bugs in extract_iter_to_sg()" from Christian
   Ehrhardt fixes a few bugs in the scatterlist code, adds in-kernel tests
   for the now-fixed bugs and fixes a leak in the test itself.
 
 - The 3 patch series "kdump: Enable LUKS-encrypted dump target support
   in ARM64 and PowerPC" from Coiby Xu eenables support of the
   LUKS-encrypted device dump target on arm64 and powerpc.
 
 - The 4 patch series "ocfs2: consolidate extent list validation into
   block read callbacks" from Joseph Qi addresses ocfs2's validation of
   extent list fields - cleanup, simplification, robustness.  (Kernel test
   robot loves mounting corrupted fs images!)

We still limit this to U8_MAX as the rdma api only uses __u8
and that's also the limit for Infiniband and RoCE*,
while iWarp would be able to support larger values at
the protocol level.

As struct smbdirect_socket_parameters will be part
of the uapi for IPPROTO_SMBDIRECT in future, change it
now even if userspace sockets won't be supported yet.

Doing an ib_dereg_mr/ib_alloc_mr dance on

it's also pointless on a broken connection

This is basically a copy of ksmbd_rdma_capable_netdev() in the
server, but this also prints a message when a device is renamed.

The differences are:
- It uses rdma_for_each_port() instead of implementing the
  same logic again.
- It returns RDMA_NODE_{UNSPECIFIED,IB_CA,RNIC} values instead of bool

This means we finally only use common functions in the server.

We still use the embedded struct smbdirect_socket and are
able to access internals, but the will be removed in the
next commits as well.

Stefan Metzmacher da20536c50 smb: server: let smbdirect_map_sges_from_iter() truncate the message boundary
smbdirect_map_sges_from_iter() already handles the case that only
a limited number of sges are available. Its return value
is data_length and the remaining bytes in the iter are
remaining_data_length.

This is now much easier and will allow us to share
more code with the client soon.

Stefan Metzmacher 73489efdda smb: server: make use of smbdirect_connection_recvmsg()
This is basically the same logic, it just operates on iov_iter_kvec()
instead of a raw buffer pointer. This allows us to use common
code between client and server.

We keep returning -EINTR instead of -ERESTARTSYS if
wait_event_interruptible() fails. I don't if this is
required, but changing it is a task for another patch.

Stefan Metzmacher 8d55169a57 smb: server: make use of smbdirect_connection_recv_io_refill[_work]()
This is basically a copy of smb_direct_post_recv_credits(), but
there are several improvements compared to the existing function:

1. We calculate the number of missing posted buffers by getting the
   difference between recv_io.credits.target and recv_io.posted.count.

   Instead of the difference between recv_io.credits.target
   and recv_io.credits.count, because recv_io.credits.count is
   only updated once a message is send to the peer.

   It was not really a problem before, because we have
   a fixed number smbdirect_recv_io buffers, so the
   loop terminated when smbdirect_connection_get_recv_io()
   returns NULL.

   But using recv_io.posted.count makes it easier to
   understand.

2. In order to tell the peer about the newly posted buffer
   and grant the credits, we only trigger the send immediate
   when we're not granting only the last possible credit.

   This is mostly a difference relative to the servers
   smb_direct_post_recv_credits() implementation,
   which should avoid useless ping pong messages.

Stefan Metzmacher 07aec3a151 smb: server: make use of smbdirect_connection_{create,destroy}_mem_pools()
This were based on smb_direct_{create,destroy}_pools() in the server.

The main logical differences are the following:

We now don't use smbdirect_connection_get_recv_io() on cleanup,
instead it uses list_for_each_entry_safe()...

We don't generate warnings if smbdirect_recv_io payload
is copied into userspace buffers. This doesn't happen
in the server anyway.

And it uses list_add_tail() just to let me feel
better when looking at the code...

These are basically copies of smb_direct_{alloc,free}_sendmsg() just
a bit simpler and with the gfp_mask mask abstracted.

For now we still use KSMBD_DEFAULT_GFP, which includes
__GFP_RETRY_MAYFAIL.

The only difference is that we use ib_dma_unmap_page() for all sges,
this simplifies the logic and doesn't matter as
ib_dma_unmap_single() and ib_dma_unmap_page() both operate
on dma_addr_t and dma_unmap_single_attrs() is just an
alias for dma_unmap_page_attrs().
We already had such an inconsistency in the client
code where we use ib_dma_unmap_single(), while we mapped
using ib_dma_map_page().
