The UFS controller of the ExynosAuto v9 SoC supports a multi-host interface
for I/O virtualization. In general, we're using para-virtualized driver to
support a block device by several virtual machines.
Multi-host functionality extends the host controller by providing register
interfaces that can be used by each VM's UFS drivers respectively. This way
we can provide direct access to the UFS device for multiple VMs similar to
PCIe SR-IOV.
We divide this M-HCI as PH (Physical Host) and VHs (Virtual Host). The PH
supports all UFSHCI functions (all SAPs) like a conventional UFSHCI but the
VH only supports data transfer functions. Thus, except UTP_CMD_SAP and
UTP_TMPSAP, the PH should handle all the physical features.
Provide an initial implementation of PH part. M-HCI can support up to four
interfaces (1 for a PH and 3 for VHs) but this patch initially supports
only 1 PH and 1 VH. For this, we uses TASK_TAG[7:5] field so TASK_TAG[4:0]
for 32 doorbell will be supported. After the PH is initiated, this will
send a ready message to VHs through a mailbox register. The message handler
is not fully implemented yet such as supporting reset / abort cases.

Casting an int explicitly to u16 when passed as an argument to a function
is not necessary.
Since prd_table and ucd_prdt_ptr both have type struct ufshcd_sg_entry *,
remove the casts from assignments of these two to each other.
This patch does not change any functionality.

Introduce an array for debugfs attributes to make it easier to add new
debugfs attributes. Change the value of the inode.i_private pointer for
debugfs attributes from a pointer to the HBA data structure to a pointer to
the attribute description for the stats attribute. Store the HBA pointer in
the private data of the parent inode instead.

Commit 73dc3c4ac7 ("scsi: ufs: Retry aborted SCSI commands instead of
completing these successfully") is not necessary. If a SCSI command is
aborted successfully the UFS controller has not modified the command status
and the command status still has the value assigned by
ufshcd_prepare_req_desc_hdr(), namely OCS_INVALID_COMMAND_STATUS. The
function ufshcd_transfer_rsp_status() requeues commands that have an
invalid command status. Hence revert commit 73dc3c4ac7.

sched_clock() is not meant to be used in portable driver code, and assuming
a particular clock frequency is not how this is meant to be used. It also
causes a build failure because of a missing header inclusion:
drivers/scsi/ufs/ufs-mediatek.c:321:12: error: implicit declaration of function 'sched_clock' [-Werror,-Wimplicit-function-declaration]
timeout = sched_clock() + retry_ms * 1000000UL;
A better interface to use here ktime_get_mono_fast_ns(), which works mostly
like ktime_get() but is safe to use inside of a suspend callback.

The SCSI error handler calls scsi_unjam_host() which can call the queue
function ufshcd_queuecommand() indirectly. The error handler changes the
state to UFSHCD_STATE_RESET while running, but error interrupts that
happen while the error handler is running could change the state to
UFSHCD_STATE_EH_SCHEDULED_NON_FATAL which would allow requests to go
through ufshcd_queuecommand() even though the error handler is running.
Block that hole by checking whether the error handler is in progress.

Callers of ufshcd_reset_and_restore() expect it to return in an operational
state. However, the code only checks direct errors and so the ufshcd_state
may not be UFSHCD_STATE_OPERATIONAL due to error interrupts.
Fix by also checking ufshcd_state, still allowing non-fatal errors which
are left for the error handler to deal with.

The device may notify the host of an extreme temperature by using the
exception event mechanism. The exception can be raised when the device’s
Tcase temperature is either too high or too low.
It is essentially up to the platform to decide what further actions need to
be taken. leave a placeholder for a designated vop for that.

Add sysfs files that expose the inline encryption capabilities of
request queues:
/sys/block/$disk/queue/crypto/max_dun_bits
/sys/block/$disk/queue/crypto/modes/$mode
/sys/block/$disk/queue/crypto/num_keyslots
Userspace can use these new files to decide what encryption settings to
use, or whether to use inline encryption at all. This also brings the
crypto capabilities in line with the other queue properties, which are
already discoverable via the queue directory in sysfs.
Design notes:
- Place the new files in a new subdirectory "crypto" to group them
together and to avoid complicating the main "queue" directory. This
also makes it possible to replace "crypto" with a symlink later if
we ever make the blk_crypto_profiles into real kobjects (see below).
- It was necessary to define a new kobject that corresponds to the
crypto subdirectory. For now, this kobject just contains a pointer
to the blk_crypto_profile. Note that multiple queues (and hence
multiple such kobjects) may refer to the same blk_crypto_profile.
An alternative design would more closely match the current kernel
data structures: the blk_crypto_profile could be a kobject itself,
located directly under the host controller device's kobject, while
/sys/block/$disk/queue/crypto would be a symlink to it.
I decided not to do that for now because it would require a lot more
changes, such as no longer embedding blk_crypto_profile in other
structures, and also because I'm not sure we can rule out moving the
crypto capabilities into 'struct queue_limits' in the future. (Even
if multiple queues share the same crypto engine, maybe the supported
data unit sizes could differ due to other queue properties.) It
would also still be possible to switch to that design later without
breaking userspace, by replacing the directory with a symlink.
- Use "max_dun_bits" instead of "max_dun_bytes". Currently, the
kernel internally stores this value in bytes, but that's an
implementation detail. It probably makes more sense to talk about
this value in bits, and choosing bits is more future-proof.
- "modes" is a sub-subdirectory, since there may be multiple supported
crypto modes, sysfs is supposed to have one value per file, and it
makes sense to group all the mode files together.
- Each mode had to be named. The crypto API names like "xts(aes)" are
not appropriate because they don't specify the key size. Therefore,
I assigned new names. The exact names chosen are arbitrary, but
they happen to match the names used in log messages in fs/crypto/.
- The "num_keyslots" file is a bit different from the others in that
it is only useful to know for performance reasons. However, it's
included as it can still be useful. For example, a user might not
want to use inline encryption if there aren't very many keyslots.

This simplifies the existing callers, as well as the future caller in

Also don't bother checking whether q is NULL, since it never is.

Add support for hardware-wrapped keys to fscrypt. Hardware-wrapped keys
are inline encryption keys which are only present in kernel memory in
ephemerally-wrapped form, and which can only be unwrapped by dedicated
hardware. Such keys are protected from certain attacks, such as cold
boot attacks. For more information, see the "Hardware-wrapped keys"
section of Documentation/block/inline-encryption.rst.
To support hardware-wrapped keys in fscrypt, we allow the fscrypt master
keys to be hardware-wrapped, and we allow encryption policies to be
flagged as needing a hardware-wrapped key. File contents encryption is
done by passing the wrapped key to the inline encryption hardware via
blk-crypto. Other fscrypt operations such as filenames encryption
continue to be done by the kernel, using the "software secret" which the
hardware derives.
Note that this feature doesn't require any filesystem-specific changes.
However it does depend on inline encryption support, and thus currently
it is only applicable to ext4 and f2fs, not to ubifs or CephFS.

Android expects. I also dropped the changes to the documentation file.

To prevent keys from being compromised if an attacker acquires read
access to kernel memory, some inline encryption hardware supports
protecting the keys in hardware without software having access to or the
ability to set the plaintext keys. Instead, software only sees "wrapped
keys", which may differ on every boot. The keys can be initially
generated either by software (in which case they need to be imported to
hardware to be wrapped), or directly by the hardware.
Add support for this type of hardware by allowing keys to be flagged as
hardware-wrapped. When used, dm-default-key will pass the wrapped key
to the inline encryption hardware to encryption metadata. The hardware
will internally unwrap the key and derive the metadata encryption key.

(cherry picked from commit 56e1e0a69a)
To prevent keys from being compromised if an attacker acquires read
access to kernel memory, some inline encryption hardware can accept keys
which are wrapped by a per-boot hardware-internal key. This avoids
needing to keep the plaintext keys in kernel memory, without restricting
the number of keys that can be used. Such keys can be initially
generated either by software (in which case they must be imported to
hardware to be wrapped) or directly by the hardware. There is also a
mechanism to derive a "software secret" for cryptographic tasks that
can't be handled by inline encryption.
To support this hardware, allow struct blk_crypto_key to represent a
hardware-wrapped key as an alternative to a standard key, and make
drivers set flags in struct blk_crypto_profile to indicate which types
of keys they support. Also add the derive_sw_secret() low-level
operation, which drivers supporting wrapped keys must implement.
For more information, see the detailed documentation which this patch
adds to Documentation/block/inline-encryption.rst.

blk_crypto_profile; ufs_hba_variant_ops::init() must do it instead.
Note that it is permitted that the blk_crypto_profile has no keyslots.
