SCSI fixes on 20250625
ixes all in drivers. ufs and megaraid_sas are small and obvious.

spi: spi-cadence-quadspi: Fix pm runtime unbalance
Having PM put sync in remove function is causing PM underflow during
remove operation. This is caused by the function, runtime_pm_get_sync,
not being called anywhere during the op. Ensure that calls to
pm_runtime_enable()/pm_runtime_disable() and
pm_runtime_get_sync()/pm_runtime_put_sync() match.

userns and mnt_idmap leak in open_tree_attr(2)
Once want_mount_setattr() has returned a positive, it does require
finish_mount_kattr() to release ->mnt_userns. Failing do_mount_setattr()
does not change that.
As the result, we can end up leaking userns and possibly mnt_idmap as
well.

attach_recursive_mnt(): do not lock the covering tree when sliding something under it
If we are propagating across the userns boundary, we need to lock the
mounts added there. However, in case when something has already
been mounted there and we end up sliding a new tree under that,
the stuff that had been there before should not get locked.
IOW, lock_mnt_tree() should be called before we reparent the
preexisting tree on top of what we are adding.

replace collect_mounts()/drop_collected_mounts() with a safer variant
collect_mounts() has several problems - one can't iterate over the results
directly, so it has to be done with callback passed to iterate_mounts();
it has an oopsable race with d_invalidate(); it creates temporary clones
of mounts invisibly for sync umount (IOW, you can have non-lazy umount
succeed leaving filesystem not mounted anywhere and yet still busy).
A saner approach is to give caller an array of struct path that would pin
every mount in a subtree, without cloning any mounts.
* collect_mounts()/drop_collected_mounts()/iterate_mounts() is gone
* collect_paths(where, preallocated, size) gives either ERR_PTR(-E...) or
a pointer to array of struct path, one for each chunk of tree visible under
'where' (i.e. the first element is a copy of where, followed by (mount,root)
for everything mounted under it - the same set collect_mounts() would give).
Unlike collect_mounts(), the mounts are *not* cloned - we just get pinning
references to the roots of subtrees in the caller's namespace.
Array is terminated by {NULL, NULL} struct path. If it fits into
preallocated array (on-stack, normally), that's where it goes; otherwise
it's allocated by kmalloc_array(). Passing 0 as size means that 'preallocated'
is ignored (and expected to be NULL).
* drop_collected_paths(paths, preallocated) is given the array returned
by an earlier call of collect_paths() and the preallocated array passed to that
call. All mount/dentry references are dropped and array is kfree'd if it's not
equal to 'preallocated'.
* instead of iterate_mounts(), users should just iterate over array
of struct path - nothing exotic is needed for that. Existing users (all in
audit_tree.c) are converted.

dm-crypt: Extend state buffer size in crypt_iv_lmk_one
Add a macro CRYPTO_MD5_STATESIZE for the Crypto API export state
size of md5 and use that in dm-crypt instead of relying on the
size of struct md5_state (the latter is currently undergoing a
transition and may shrink).

The sole caller of spacemit_i2c_xfer_msg() is spacemit_i2c_xfer(),
which is the i2c_algorithm->xfer callback function. It currently
does not save the value returned by spacemit_i2c_xfer_msg().
The result is that transfer errors go unreported, and a caller
has no indication anything is wrong.
When this code was out for review, the return value *was* checked
in early versions. But for some reason, that assignment got dropped
between versions 5 and 6 of the series, perhaps related to reworking
the code to merge spacemit_i2c_xfer_core() into spacemit_i2c_xfer().
Simply assigning the value returned to "ret" fixes the problem.

smb: Log an error when close_all_cached_dirs fails
Under low-memory conditions, close_all_cached_dirs() can't move the
dentries to a separate list to dput() them once the locks are dropped.
This will result in a "Dentry still in use" error, so add an error
message that makes it clear this is what happened:
[ 495.281119] CIFS: VFS: \\otters.example.com\share Out of memory while dropping dentries

Also, bail out of looping through all tcons as soon as a single
allocation fails, since we're already in trouble, and kmalloc() attempts
for subseqeuent tcons are likely to fail just like the first one did.

smb: client: fix first command failure during re-negotiation
after fabc4ed200f9, server_unresponsive add a condition to check whether client
need to reconnect depending on server->lstrp. When client failed to reconnect
for some time and abort connection, server->lstrp is updated for the last time.
In the following scene, server->lstrp is too old. This cause next command
failure in re-negotiation rather than waiting for re-negotiation done.
1. mount -t cifs -o username=Everyone,echo_internal=10 //$server_ip/export /mnt
2. ssh $server_ip "echo b > /proc/sysrq-trigger &"
3. ls /mnt
4. sleep 21s
5. ssh $server_ip "service firewalld stop"
6. ls # return EHOSTDOWN
If the interval between 5 and 6 is too small, 6 may trigger sending negotiation
request. Before backgrounding cifsd thread try to receive negotiation response
from server in cifs_readv_from_socket, server_unresponsive may trigger
cifs_reconnect which cause 6 to be failed:
ls thread
----------------
smb2_negotiate
server->tcpStatus = CifsInNegotiate
compound_send_recv
wait_for_compound_request
cifsd thread
----------------
cifs_readv_from_socket
server_unresponsive
server->tcpStatus == CifsInNegotiate && jiffies > server->lstrp + 20s
cifs_reconnect
cifs_abort_connection: mid_state = MID_RETRY_NEEDED
ls thread
----------------
cifs_sync_mid_result return EAGAIN
smb2_negotiate return EHOSTDOWN
Though server->lstrp means last server response time, it is updated in
cifs_abort_connection and cifs_get_tcp_session. We can also update server->lstrp
before switching into CifsInNegotiate state to avoid failure in 6.

The main fix that really needs to get in is the revert of the patch
adding the new mtd_master class, because it entirely fails the partitioning if a specific Kconfig option is set. We need to think how to handle that differently, so let's revert it as we need to get back to the pen and paper situation again. Otherwise the definition of some Winbond SPI NAND chips are receiving some fixes (geometry and maximum frequency, mostly). And finally a small memory leak gets also fixed. -----BEGIN PGP SIGNATURE----- iQEzBAABCAAdFiEE9HuaYnbmDhq/XIDIJWrqGEe9VoQFAmhVfg0ACgkQJWrqGEe9 VoTa8wf7BaY8T+mpA6zbgou4LBNFiqcB+NkL8N4uFOaVsGQYQfb5SX6m1CKitD8y oIbkwYZI7c2R3ZuQ8vj6PgKwbG7HJrmSfO5dbWoamNJ6cE2Y1rQFJUCyE98zrO/g MsZBy2PjBM3q5YRwuA0YzzHWQec4bXpeQlxUhk+VYGW/2BJdROUzmLebPz7cuKKx m+VVLdVEByu41JaLE9j3+ntfFnoY3Fp5DooheGCCEAdHEv+drfcbLv2TEiy9wyCv LLhau6MPaBDgL0+VIZd91Lgys7stFYtbPBSlItRsdZ91mRIVt8AtJAA0k0t8lQGo srb8eSEbTeIVFkJjGC43utY6mIic1A== =5vwJ -----END PGP SIGNATURE----- Merge tag 'mtd/fixes-for-6.16-rc3' of git://git.kernel.org/pub/scm/linux/kernel/git/mtd/linux Pull mtd fixes from Miquel Raynal: "The main fix that really needs to get in is the revert of the patch adding the new mtd_master class, because it entirely fails the partitioning if a specific Kconfig option is set.

rcu: Return early if callback is not specified
Currently the call_rcu() API does not check whether a callback pointer is NULL. If NULL is passed, rcu_core() will try to invoke it, resulting in NULL pointer dereference and a kernel crash. To prevent this and improve debuggability, this patch adds a check for NULL and emits a kernel stack trace to help identify a faulty caller.

KVM: TDX: Exit to userspace for GetTdVmCallInfo
Exit to userspace for TDG.VP.VMCALL<GetTdVmCallInfo> via KVM_EXIT_TDX, to allow userspace to provide information about the support of TDVMCALLs when r12 is 1 for the TDVMCALLs beyond the GHCI base API. GHCI spec defines the GHCI base TDVMCALLs: <GetTdVmCallInfo>, <MapGPA>, <ReportFatalError>, <Instruction.CPUID>, <#VE.RequestMMIO>, <Instruction.HLT>, <Instruction.IO>, <Instruction.RDMSR> and <Instruction.WRMSR>. They must be supported by VMM to support TDX guests. For GetTdVmCallInfo - When leaf (r12) to enumerate TDVMCALL functionality is set to 0, successful execution indicates all GHCI base TDVMCALLs listed above are supported. Update the KVM TDX document with the set of the GHCI base APIs. - When leaf (r12) to enumerate TDVMCALL functionality is set to 1, it indicates the TDX guest is querying the supported TDVMCALLs beyond the GHCI base TDVMCALLs. Exit to userspace to let userspace set the TDVMCALL sub-function bit(s) accordingly to the leaf outputs. KVM could set the TDVMCALL bit(s) supported by itself when the TDVMCALLs don't need support from userspace after returning from userspace and before entering guest. Currently, no such TDVMCALLs implemented, KVM just sets the values returned from userspace.

KVM: TDX: Handle TDG.VP.VMCALL<GetQuote>
Handle TDVMCALL for GetQuote to generate a TD-Quote. GetQuote is a doorbell-like interface used by TDX guests to request VMM to generate a TD-Quote signed by a service hosting TD-Quoting Enclave operating on the host. A TDX guest passes a TD Report (TDREPORT_STRUCT) in a shared-memory area as parameter. Host VMM can access it and queue the operation for a service hosting TD-Quoting enclave. When completed, the Quote is returned via the same shared-memory area. KVM only checks the GPA from the TDX guest has the shared-bit set and drops the shared-bit before exiting to userspace to avoid bleeding the shared-bit into KVM's exit ABI. KVM forwards the request to userspace VMM (e.g. QEMU) and userspace VMM queues the operation asynchronously. KVM sets the return code according to the 'ret' field set by userspace to notify the TDX guest whether the request has been queued successfully or not. When the request has been queued successfully, the TDX guest can poll the status field in the shared-memory area to check whether the Quote generation is completed or not. When completed, the generated Quote is returned via the same buffer. Add KVM_EXIT_TDX as a new exit reason to userspace. Userspace is required to handle the KVM exit reason as the initial support for TDX, by reentering KVM to ensure that the TDVMCALL is complete. While at it, add a note that KVM_EXIT_HYPERCALL also requires reentry with KVM_RUN.

KVM: TDX: Add new TDVMCALL status code for unsupported subfuncs
Add the new TDVMCALL status code TDVMCALL_STATUS_SUBFUNC_UNSUPPORTED and return it for unimplemented TDVMCALL subfunctions. Returning TDVMCALL_STATUS_INVALID_OPERAND when a subfunction is not implemented is vague because TDX guests can't tell the error is due to the subfunction is not supported or an invalid input of the subfunction. New GHCI spec adds TDVMCALL_STATUS_SUBFUNC_UNSUPPORTED to avoid the ambiguity. Use it instead of TDVMCALL_STATUS_INVALID_OPERAND. Before the change, for common guest implementations, when a TDX guest receives TDVMCALL_STATUS_INVALID_OPERAND, it has two cases: 1. Some operand is invalid. It could change the operand to another value retry. 2. The subfunction is not supported. For case 1, an invalid operand usually means the guest implementation bug. Since the TDX guest can't tell which case is, the best practice for handling TDVMCALL_STATUS_INVALID_OPERAND is stopping calling such leaf, treating the failure as fatal if the TDVMCALL is essential or ignoring it if the TDVMCALL is optional. With this change, TDVMCALL_STATUS_SUBFUNC_UNSUPPORTED could be sent to old TDX guest that do not know about it, but it is expected that the guest will make the same action as TDVMCALL_STATUS_INVALID_OPERAND. Currently, no known TDX guest checks TDVMCALL_STATUS_INVALID_OPERAND specifically; for example Linux just checks for success.
