Pull vfs mount updates from Christian Brauner:
"This contains some work around mount api handling:
- Output the warning message for mnt_too_revealing() triggered during
fsmount() to the fscontext log. This makes it possible for the
mount tool to output appropriate warnings on the command line.
For example, with the newest fsopen()-based mount(8) from
util-linux, the error messages now look like:
# mount -t proc proc /tmp
mount: /tmp: fsmount() failed: VFS: Mount too revealing.
dmesg(1) may have more information after failed mount system call.
- Do not consume fscontext log entries when returning -EMSGSIZE
Userspace generally expects APIs that return -EMSGSIZE to allow for
them to adjust their buffer size and retry the operation.
However, the fscontext log would previously clear the message even
in the -EMSGSIZE case.
Given that it is very cheap for us to check whether the buffer is
too small before we remove the message from the ring buffer, let's
just do that instead.
- Drop an unused argument from do_remount()"
* tag 'vfs-6.18-rc1.mount' of git://git.kernel.org/pub/scm/linux/kernel/git/vfs/vfs:
vfs: fs/namespace.c: remove ms_flags argument from do_remount
selftests/filesystems: add basic fscontext log tests
fscontext: do not consume log entries when returning -EMSGSIZE
vfs: output mount_too_revealing() errors to fscontext
docs/vfs: Remove mentions to the old mount API helpers
fscontext: add custom-prefix log helpers

When calling in listmount() mnt_ns_release() may be passed a NULL
pointer. Handle that case gracefully.

Pull misc vfs updates from Christian Brauner:
"This contains the usual selections of misc updates for this cycle.
Features:
- Add "initramfs_options" parameter to set initramfs mount options.
This allows to add specific mount options to the rootfs to e.g.,
limit the memory size
- Add RWF_NOSIGNAL flag for pwritev2()
Add RWF_NOSIGNAL flag for pwritev2. This flag prevents the SIGPIPE
signal from being raised when writing on disconnected pipes or
sockets. The flag is handled directly by the pipe filesystem and
converted to the existing MSG_NOSIGNAL flag for sockets
- Allow to pass pid namespace as procfs mount option
Ever since the introduction of pid namespaces, procfs has had very
implicit behaviour surrounding them (the pidns used by a procfs
mount is auto-selected based on the mounting process's active
pidns, and the pidns itself is basically hidden once the mount has
been constructed)
This implicit behaviour has historically meant that userspace was
required to do some special dances in order to configure the pidns
of a procfs mount as desired. Examples include:
* In order to bypass the mnt_too_revealing() check, Kubernetes
creates a procfs mount from an empty pidns so that user
namespaced containers can be nested (without this, the nested
containers would fail to mount procfs)
But this requires forking off a helper process because you cannot
just one-shot this using mount(2)
* Container runtimes in general need to fork into a container
before configuring its mounts, which can lead to security issues
in the case of shared-pidns containers (a privileged process in
the pidns can interact with your container runtime process)
While SUID_DUMP_DISABLE and user namespaces make this less of an
issue, the strict need for this due to a minor uAPI wart is kind
of unfortunate
Things would be much easier if there was a way for userspace to
just specify the pidns they want. So this pull request contains
changes to implement a new "pidns" argument which can be set
using fsconfig(2):
fsconfig(procfd, FSCONFIG_SET_FD, "pidns", NULL, nsfd);
fsconfig(procfd, FSCONFIG_SET_STRING, "pidns", "/proc/self/ns/pid", 0);
or classic mount(2) / mount(8):
// mount -t proc -o pidns=/proc/self/ns/pid proc /tmp/proc
mount("proc", "/tmp/proc", "proc", MS_..., "pidns=/proc/self/ns/pid");
Cleanups:
- Remove the last references to EXPORT_OP_ASYNC_LOCK
- Make file_remove_privs_flags() static
- Remove redundant __GFP_NOWARN when GFP_NOWAIT is used
- Use try_cmpxchg() in start_dir_add()
- Use try_cmpxchg() in sb_init_done_wq()
- Replace offsetof() with struct_size() in ioctl_file_dedupe_range()
- Remove vfs_ioctl() export
- Replace rwlock() with spinlock in epoll code as rwlock causes
priority inversion on preempt rt kernels
- Make ns_entries in fs/proc/namespaces const
- Use a switch() statement() in init_special_inode() just like we do
in may_open()
- Use struct_size() in dir_add() in the initramfs code
- Use str_plural() in rd_load_image()
- Replace strcpy() with strscpy() in find_link()
- Rename generic_delete_inode() to inode_just_drop() and
generic_drop_inode() to inode_generic_drop()
- Remove unused arguments from fcntl_{g,s}et_rw_hint()
Fixes:
- Document @name parameter for name_contains_dotdot() helper
- Fix spelling mistake
- Always return zero from replace_fd() instead of the file descriptor
number
- Limit the size for copy_file_range() in compat mode to prevent a
signed overflow
- Fix debugfs mount options not being applied
- Verify the inode mode when loading it from disk in minixfs
- Verify the inode mode when loading it from disk in cramfs
- Don't trigger automounts with RESOLVE_NO_XDEV
If openat2() was called with RESOLVE_NO_XDEV it didn't traverse
through automounts, but could still trigger them
- Add FL_RECLAIM flag to show_fl_flags() macro so it appears in
tracepoints
- Fix unused variable warning in rd_load_image() on s390
- Make INITRAMFS_PRESERVE_MTIME depend on BLK_DEV_INITRD
- Use ns_capable_noaudit() when determining net sysctl permissions
- Don't call path_put() under namespace semaphore in listmount() and
statmount()"

possible, so do it in the first send work request.

commit 20cf4e026730 ("rdma: Enable ib_alloc_cq to spread work over a
device's comp_vectors") happened before ksmbd was upstreamed,
but after the out of tree ksmbd (a.k.a. cifsd) was developed.
So we still used ib_alloc_cq().

transport_rdma.c
There is a mix of using spin_lock() and spin_lock_irq(), which
is confusing as IB_POLL_WORKQUEUE is used and no code would
be called from any interrupt. So using spin_lock() or even
mutexes would be ok.
But we'll soon share common code with the client, which uses
IB_POLL_SOFTIRQ.
And Documentation/kernel-hacking/locking.rst section
"Cheat Sheet For Locking" says:
- Otherwise (== data can be touched in an interrupt), use
spin_lock_irqsave() and
spin_unlock_irqrestore().
So in order to keep it simple and safe we use that version
now. It will help merging functions into common code and
have consistent locking in all cases.

With this commit the server only uses struct smbdirect_socket!
It doesn't use the idle timer yet, but it will be added soon,
from there we'll be ready split common functions.

smbdirect_socket_parameters.{initiator_depth,responder_resources}
This will make it easier to specify these from the outside of the core
code first and then negotiate the value with the peer.

and change to 5s
The server negotiations timer is just 5 seconds in Windows, so use the
same. See [MS-SMBD] 3.1.7.2 Connection Arrival.

We should use the per connection value.
And for TCP return NT_STATUS_INVALID_PARAMETER if any
SMB2_CHANNEL_RDMA_V1* is used.

At best they gain nothing, at worst we procude real bugs.

The spelling of smb_trans_direct_transfort was wrong anyway
and we don't need the logic twice.

(At least for me) the logic maintaining the count of posted
recv_io messages and the count of granted credits is much
easier to understand.
From there we can easily calculate the number of new_credits we'll
grant to the peer in outgoing send_io messages.
This will simplify the move to common logic that can be
shared between client and server in the following patches.

limit the range
The clients sends the initial recv_credit_target in the negotiate req,
so we should use that.
We also limit the range between 1 and our local defined
sp->recv_credit_max. This will simplify further logic changes.
