We need a way to tell which type of keys the inline crypto hardware
supports (standard, wrapped, or both), so that fallbacks can be used
when needed (either blk-crypto-fallback, or fscrypt fs-layer crypto).
We can't simply assume that
keyslot_mgmt_ll_ops::derive_raw_secret == NULL
means only standard keys are supported and that
keyslot_mgmt_ll_ops::derive_raw_secret != NULL
means that only wrapped keys are supported, because device-mapper
devices always implement this method. Also, hardware might support both
types of keys.
Therefore, add a field keyslot_manager::features which contains a
bitmask of flags which indicate the supported types of keys. Drivers
will need to fill this in. This patch makes the UFS standard crypto
code set BLK_CRYPTO_FEATURE_STANDARD_KEYS, but UFS variant drivers may
need to set BLK_CRYPTO_FEATURE_WRAPPED_KEYS instead.
Then, make keyslot_manager_crypto_mode_supported() take the key type
into account.

If blk-crypto-fallback is needed but is disabled by kconfig, make
blk_crypto_start_using_mode() return an error rather than succeeding.
Use ENOPKG, which matches the error code used by fscrypt when crypto API
support is missing with fs-layer encryption.
Also, if blk-crypto-fallback is needed but the algorithm is missing from
the kernel's crypto API, change the error code from ENOENT to ENOPKG.
This is needed for VtsKernelEncryptionTest to pass on some devices.

[ Upstream commit 14afc59361976c0ba39e3a9589c3eaa43ebc7e1d ]
The bfq_find_set_group() function takes as input a blkcg (which represents
a cgroup) and retrieves the corresponding bfq_group, then it updates the
bfq internal group hierarchy (see comments inside the function for why
this is needed) and finally it returns the bfq_group.
In the hierarchy update cycle, the pointer holding the correct bfq_group
that has to be returned is mistakenly used to traverse the hierarchy
bottom to top, meaning that in each iteration it gets overwritten with the
parent of the current group. Since the update cycle stops at root's
children (depth = 2), the overwrite becomes a problem only if the blkcg
describes a cgroup at a hierarchy level deeper than that (depth > 2). In
this case the root's child that happens to be also an ancestor of the
correct bfq_group is returned. The main consequence is that processes
contained in a cgroup at depth greater than 2 are wrongly placed in the
group described above by BFQ.
This commits fixes this problem by using a different bfq_group pointer in
the update cycle in order to avoid the overwrite of the variable holding
the original group reference.

blk-crypto-fallback does not support wrapped keys, hence
prevent falling back when program_key fails. Add 'is_hw_wrapped'
flag to blk-crypto-key to mention if the key is wrapped
when the key is initialized.
Bug: 147209885
Test: Validate FBE, simulate a failure in the underlying blk
device and ensure the call fails without falling back
to blk-crypto-fallback.

The call to pm_runtime_get_sync() in ufshcd_program_key() can deadlock
because it waits for the UFS controller to be resumed, but it can itself
be reached while resuming the UFS controller via:
- ufshcd_runtime_resume()
- ufshcd_resume()
- ufshcd_reset_and_restore()
- ufshcd_host_reset_and_restore()
- ufshcd_hba_enable()
- ufshcd_hba_execute_hce()
- ufshcd_hba_start()
- ufshcd_crypto_enable()
- keyslot_manager_reprogram_all_keys()
- ufshcd_crypto_keyslot_program()
- ufshcd_program_key()
But pm_runtime_get_sync() *is* needed when evicting a key. Also, on
pre-4.20 kernels it's needed when programming a keyslot for a bio since
the block layer used to resume the device in a different place.
Thus, it's hard for drivers to know what to do in .keyslot_program() and
.keyslot_evict(). In old kernels it may even be impossible unless we
were to pass more information down from the keyslot_manager.
There's also another possible deadlock: keyslot programming and eviction
take ksm->lock for write and then resume the device, which may result in
ksm->lock being taken again via the above call stack. To fix this, we
should resume the device before taking ksm->lock.
Fix these problems by moving to a better design where the block layer
(namely, the keyslot manager) handles runtime power management instead
of drivers. This is analogous to the block layer's existing runtime
power management support (blk-pm), which handles resuming devices when
bios are submitted to them so that drivers don't need to handle it.
Test: Tested on coral with:
echo 5 > /sys/bus/platform/devices/1d84000.ufshc/rpm_lvl
sleep 30
touch /data && sync # hangs before this fix
Also verified via kvm-xfstests that blk-crypto-fallback continues
to work both with and without CONFIG_PM=y.

commit 4800bf7bc8c725e955fcbc6191cc872f43f506d3 upstream.
A discard cleanup merged into 4.20-rc2 causes fstests xfs/259 to
fall into an endless loop in the discard code. The test is creating
a device that is exactly 2^32 sectors in size to test mkfs boundary
conditions around the 32 bit sector overflow region.
mkfs issues a discard for the entire device size by default, and
hence this throws a sector count of 2^32 into
blkdev_issue_discard(). It takes the number of sectors to discard as
a sector_t - a 64 bit value.
The commit ba5d73851e71 ("block: cleanup __blkdev_issue_discard")
takes this sector count and casts it to a 32 bit value before
comapring it against the maximum allowed discard size the device
has. This truncates away the upper 32 bits, and so if the lower 32
bits of the sector count is zero, it starts issuing discards of
length 0. This causes the code to fall into an endless loop, issuing
a zero length discards over and over again on the same sector.
Fixes: ba5d73851e71 ("block: cleanup __blkdev_issue_discard")

[ Upstream commit 1a67356e9a4829da2935dd338630a550c59c8489 ]
It is wrong to use bio->bi_vcnt to figure out how many segments
there are in the bio even though CLONED flag isn't set on this bio,
because this bio may be splitted or advanced.
So always use bio_segments() in blk_recount_segments(), and it shouldn't
cause any performance loss now because the physical segment number is figured
out in blk_queue_split() and BIO_SEG_VALID is set meantime since
bdced438ac ("block: setup bi_phys_segments after splitting").

Add a device-mapper target "dm-default-key" which assigns an encryption
key to bios that aren't for the contents of an encrypted file.
This ensures that all blocks on-disk will be encrypted with some key,
without the performance hit of file contents being encrypted twice when
fscrypt (File-Based Encryption) is used.
It is only appropriate to use dm-default-key when key configuration is
tightly controlled, like it is in Android, such that all fscrypt keys
are at least as hard to compromise as the default key.
Compared to the original version of dm-default-key, this has been
modified to use the new vendor-independent inline encryption framework
(which works even when no inline encryption hardware is present), the
table syntax has been changed to match dm-crypt, and support for
specifying Adiantum encryption has been added. These changes also mean
that dm-default-key now always explicitly specifies the DUN (the IV).
Also, to handle f2fs moving blocks of encrypted files around without the
key, and to handle ext4 and f2fs filesystems mounted without
'-o inlinecrypt', the mapping logic is no longer "set a key on the bio
if it doesn't have one already", but rather "set a key on the bio unless
the bio has the bi_skip_dm_default_key flag set". Filesystems set this
flag on *all* bios for encrypted file contents, regardless of whether
they are encrypting/decrypting the file using inline encryption or the
traditional filesystem-layer encryption, or moving the raw data.
For the bi_skip_dm_default_key flag, a new field in struct bio is used
rather than a bit in bi_opf so that fscrypt_set_bio_crypt_ctx() can set
the flag, minimizing the changes needed to filesystems. (bi_opf is
usually overwritten after fscrypt_set_bio_crypt_ctx() is called.)

Update the device-mapper core to support exposing the inline crypto
support of the underlying device(s) through the device-mapper device.
This works by creating a "passthrough keyslot manager" for the dm
device, which declares support for the set of (crypto_mode,
data_unit_size) combos which all the underlying devices support. When a
supported combo is used, the bio cloning code handles cloning the crypto
context to the bios for all the underlying devices. When an unsupported
combo is used, the blk-crypto fallback is used as usual.
Crypto support on each underlying device is ignored unless the
corresponding dm target opts into exposing it. This is needed because
for inline crypto to semantically operate on the original bio, the data
must not be transformed by the dm target. Thus, targets like dm-linear
can expose crypto support of the underlying device, but targets like
dm-crypt can't. (dm-crypt could use inline crypto itself, though.)
When a key is evicted from the dm device, it is evicted from all
underlying devices.

The regular keyslot manager is designed for devices that have a small
number of keyslots that need to be programmed with keys ahead of time,
and bios that are sent to the device need to be tagged with a keyslot
index.
Some inline encryption hardware may not have any limitations on the
number of keyslot, and may instead allow each bio to be tagged with
a raw key, data unit number, etc. rather than a pre-programmed keyslot's
index. These devices don't need any sort of keyslot management, and it's
better for these devices not to have to allocate a regular keyslot
manager with some fixed number of keyslots. These devices can instead
set up a passthrough keyslot manager in their request queue, which
require less resources than regular keyslot managers, as they simply
do no-ops when trying to program keys into slots.
Separately, the device mapper may map over devices that have inline
encryption hardware, and it wants to pass the key along to the
underlying hardware. While the DM layer can expose inline encryption
capabilities by setting up a regular keyslot manager with some fixed
number of keyslots in the dm device's request queue, this only wastes
memory since the keys programmed into the dm device's request queue
will never be used. Instead, it's better to set up a passthrough
keyslot manager for dm devices.

Export the blk-crypto symbols needed for modules to use inline crypto.
These would have already been exported, except that so far they've only
been used by fs/crypto/, which is no longer modular.

While we're waiting for v7 of the inline crypto patchset, fix some bugs
that made it into the v6 patchset, including one that caused bios with
an encryption context to never be merged, and one that could cause
non-contiguous pages to incorrectly added to a bio.

commit ad6bf88a6c19a39fb3b0045d78ea880325dfcf15 upstream.
Logical block size has type unsigned short. That means that it can be at
most 32768. However, there are architectures that can run with 64k pages
(for example arm64) and on these architectures, it may be possible to
create block devices with 64k block size.
For exmaple (run this on an architecture with 64k pages):
Mount will fail with this error because it tries to read the superblock using 2-sector
access:
device-mapper: writecache: I/O is not aligned, sector 2, size 1024, block size 65536
EXT4-fs (dm-0): unable to read superblock
This patch changes the logical block size from unsigned short to unsigned
int to avoid the overflow.

Some inline encryption hardware supports protecting the keys in hardware
and only exposing wrapped keys to software. To use this capability,
userspace must provide a hardware-wrapped key rather than a raw key.
However, users of inline encryption in the kernel won't necessarily use
the user-specified key directly for inline encryption. E.g. with
fscrypt with IV_INO_LBLK_64 policies, each user-provided key is used to
derive a file contents encryption key, filenames encryption key, and key
identifier. Since inline encryption can only be used with file
contents, if the user were to provide a wrapped key there would
(naively) be no way to encrypt filenames or derive the key identifier.
This problem is solved by designing the hardware to internally use the
unwrapped key as input to a KDF from which multiple cryptographically
isolated keys can be derived, including both the inline crypto key (not
exposed to software) and a secret that *is* exposed to software.
Add a function to the keyslot manager to allow upper layers to request
this software secret from a hardware-wrapped key.

Currently, blk-crypto uses the algorithm to determine the size of keys.
However, some inline encryption hardware supports protecting keys from
software by wrapping the storage keys with an ephemeral key. Since
these wrapped keys are not of a fixed size, add the capability to
provide the key size when initializing a blk_crypto_key, and update the
keyslot manager to take size into account when comparing keys.

Changes v5 => v6:
- Blk-crypto's kernel crypto API fallback is no longer restricted to
8-byte DUNs. It's also now separately configurable from blk-crypto, and
can be disabled entirely, while still allowing the kernel to use inline
encryption hardware. Further, struct bio_crypt_ctx takes up less space,
and no longer contains the information needed by the crypto API
fallback - the fallback allocates the required memory when necessary.
- Blk-crypto now supports all file content encryption modes supported by
fscrypt.
- Fixed bio merging logic in blk-merge.c
- Fscrypt now supports inline encryption with the direct key policy, since
blk-crypto now has support for larger DUNs.
- Keyslot manager now uses a hashtable to lookup which keyslot contains
any particular key (thanks Eric!)
- Fscrypt support for inline encryption now handles filesystems with
multiple underlying block devices (thanks Eric!)
- Numerous cleanups

the bio(s) which is allocated before this failing will leak. The
refcount of the bio(s) is init to 1 and increased to 2 by calling
bio_get(), but __blk_rq_unmap_user() only decrease it to 1, so
the bio cannot be freed. Fix it by calling blk_rq_unmap_user().

commit d2c9be89f8ebe7ebcc97676ac40f8dec1cf9b43a upstream.
8962842ca5ab ("blk-mq: avoid sysfs buffer overflow with too many CPU cores")
avoids sysfs buffer overflow, and reserves one character for line break.
However, the last snprintf() doesn't get correct 'size' parameter passed
in, so fixed it.

commit 8962842ca5abdcf98e22ab3b2b45a103f0408b95 upstream.
It is reported that sysfs buffer overflow can be triggered if the system
has too many CPU cores(>841 on 4K PAGE_SIZE) when showing CPUs of
hctx via /sys/block/$DEV/mq/$N/cpu_list.
Use snprintf to avoid the potential buffer overflow.
This version doesn't change the attribute format, and simply stops
showing CPU numbers if the buffer is going to overflow.

be waken up, then IO hang is caused.
So fixes this issue by moving rq_qos_exit() after queue is frozen.

[ Upstream commit 69840466086d2248898020a08dda52732686c4e6 ]
There are two cases when handle DISCARD merge.
If max_discard_segments == 1, the bios/requests need to be contiguous
to merge. If max_discard_segments > 1, it takes every bio as a range
and different range needn't to be contiguous.
But now, attempt_merge screws this up. It always consider contiguity
for DISCARD for the case max_discard_segments > 1 and cannot merge
contiguous DISCARD for the case max_discard_segments == 1, because
rq_attempt_discard_merge always returns false in this case.
This patch fixes both of the two cases above.

[ Upstream commit c8765de0adfcaaf4ffb2d951e07444f00ffa9453 ]
To reduce latency for interactive and soft real-time applications, bfq
privileges the bfq_queues containing the I/O of these
applications. These privileged queues, referred-to as weight-raised
queues, get a much higher share of the device throughput
w.r.t. non-privileged queues. To preserve this higher share, the I/O
of any non-weight-raised queue must be plugged whenever a sync
weight-raised queue, while being served, remains temporarily empty. To
attain this goal, bfq simply plugs any I/O (from any queue), if a sync
weight-raised queue remains empty while in service.
Unfortunately, this plugging typically lowers throughput with random
I/O, on devices with internal queueing (because it reduces the filling
level of the internal queues of the device).
This commit addresses this issue by restricting the cases where
plugging is performed: if a sync weight-raised queue remains empty
while in service, then I/O plugging is performed only if some of the
active bfq_queues are *not* weight-raised (which is actually the only
circumstance where plugging is needed to preserve the higher share of
the throughput of weight-raised queues). This restriction proved able
to boost throughput in really many use cases needing only maximum
throughput.

[ Upstream commit d0edc2473be9d70f999282e1ca7863ad6ae704dc ]
The Achilles' heel of BFQ is its failing to reach a high throughput
with sync random I/O on flash storage with internal queueing, in case
the processes doing I/O have differentiated weights.
The cause of this failure is as follows. If at least two processes do
sync I/O, and have a different weight from each other, then BFQ plugs
I/O dispatching every time one of these processes, while it is being
served, remains temporarily without pending I/O requests. This
plugging is necessary to guarantee that every process enjoys a
bandwidth proportional to its weight; but it empties the internal
queue(s) of the drive. And this kills throughput with random I/O. So,
if some processes have differentiated weights and do both sync and
random I/O, the end result is a throughput collapse.
This commit tries to counter this problem by injecting the service of
other processes, in a controlled way, while the process in service
happens to have no I/O. This injection is performed only if the medium
is non rotational and performs internal queueing, and the process in
service does random I/O (service injection might be beneficial for
sequential I/O too, we'll work on that).
As an example of the benefits of this commit, on a PLEXTOR PX-256M5S
SSD, and with five processes having differentiated weights and doing
sync random 4KB I/O, this commit makes the throughput with bfq grow by
400%, from 25 to 100MB/s. This higher throughput is 10MB/s lower than
that reached with none. As some less random I/O is added to the mix,
the throughput becomes equal to or higher than that with none.
This commit is a very first attempt to recover throughput without
losing control, and certainly has many limitations. One is, e.g., that
the processes whose service is injected are not chosen so as to
distribute the extra bandwidth they receive in accordance to their
weights. Thus there might be loss of weighted fairness in some
cases. Anyway, this loss concerns extra service, which would not have
been received at all without this commit. Other limitations and issues
will probably show up with usage.

We introduce blk-crypto, which manages programming keyslots for struct
bios. With blk-crypto, filesystems only need to call bio_crypt_set_ctx with
the encryption key, algorithm and data_unit_num; they don't have to worry
about getting a keyslot for each encryption context, as blk-crypto handles
that. Blk-crypto also makes it possible for layered devices like device
mapper to make use of inline encryption hardware.
Blk-crypto delegates crypto operations to inline encryption hardware when
available, and also contains a software fallback to the kernel crypto API.
For more details, refer to Documentation/block/inline-encryption.rst.

bio_crypt_should_process would WARN that the bio did not have a
keyslot in any keyslot manager even when we were on the decrypt path
of blk-crypto, which is a bug. The WARN is now conditional on the
caller being responible for handling encryption rather than blk-crypto
(i.e. the WARN happens only if this function return true).

We must have some way of letting a storage device driver know what
encryption context it should use for en/decrypting a request. However,
it's the filesystem/fscrypt that knows about and manages encryption
contexts. As such, when the filesystem layer submits a bio to the block
layer, and this bio eventually reaches a device driver with support for
inline encryption, the device driver will need to have been told the
encryption context for that bio.
We want to communicate the encryption context from the filesystem layer
to the storage device along with the bio, when the bio is submitted to the
block layer. To do this, we add a struct bio_crypt_ctx to struct bio, which
can represent an encryption context (note that we can't use the bi_private
field in struct bio to do this because that field does not function to pass
information across layers in the storage stack). We also introduce various
functions to manipulate the bio_crypt_ctx and make the bio/request merging
logic aware of the bio_crypt_ctx.

Inline Encryption hardware allows software to specify an encryption context
(an encryption key, crypto algorithm, data unit num, data unit size, etc.)
along with a data transfer request to a storage device, and the inline
encryption hardware will use that context to en/decrypt the data. The
inline encryption hardware is part of the storage device, and it
conceptually sits on the data path between system memory and the storage
device.
Inline Encryption hardware implementations often function around the
concept of "keyslots". These implementations often have a limited number
of "keyslots", each of which can hold an encryption context (we say that
an encryption context can be "programmed" into a keyslot). Requests made
to the storage device may have a keyslot associated with them, and the
inline encryption hardware will en/decrypt the data in the requests using
the encryption context programmed into that associated keyslot. As
keyslots are limited, and programming keys may be expensive in many
implementations, and multiple requests may use exactly the same encryption
contexts, we introduce a Keyslot Manager to efficiently manage keyslots.
The keyslot manager also functions as the interface that upper layers will
use to program keys into inline encryption hardware. For more information
on the Keyslot Manager, refer to documentation found in
block/keyslot-manager.c and linux/keyslot-manager.h.

[ Upstream commit b0814361a25cba73a224548843ed92d8ea78715a ]
blkcg_print_stat() iterates blkgs under RCU and doesn't test whether
the blkg is online. This can call into pd_stat_fn() on a pd which is
still being initialized leading to an oops.
The heaviest operation - recursively summing up rwstat counters - is
already done while holding the queue_lock. Expand queue_lock to cover
the other operations and skip the blkg if it isn't online yet. The
online state is protected by both blkcg and queue locks, so this
guarantees that only online blkgs are processed.

commit b84477d3ebb96294f87dc3161e53fa8fe22d9bfd upstream.
scale_up wakes up waiters after scaling up. But after scaling max, it
should not wake up more waiters as waiters will not have anything to
do. This patch fixes this by making scale_up (and also scale_down)
return when threshold is reached.
This bug causes increased fdatasync latency when fdatasync and dd
conv=sync are performed in parallel on 4.19 compared to 4.14. This
bug was introduced during refactoring of blk-wbt code.

psi tracks the time tasks wait for refaulting pages to become
uptodate, but it does not track the time spent submitting the IO. The
submission part can be significant if backing storage is contended or
when cgroup throttling (io.latency) is in effect - a lot of time is
spent in submit_bio(). In that case, we underreport memory pressure.
Annotate submit_bio() to account submission time as memory stall when
the bio is reading userspace workingset pages.

[ Upstream commit cb8acabbe33b110157955a7425ee876fb81e6bbc ]
Commit 7211aef86f79 ("block: mq-deadline: Fix write completion
handling") added a call to blk_mq_sched_mark_restart_hctx() in
dd_dispatch_request() to make sure that write request dispatching does
not stall when all target zones are locked. This fix left a subtle race
when a write completion happens during a dispatch execution on another
CPU:
CPU 0: Dispatch CPU1: write completion
dd_dispatch_request()
lock(&dd->lock);
...
lock(&dd->zone_lock); dd_finish_request()
rq = find request lock(&dd->zone_lock);
unlock(&dd->zone_lock);
zone write unlock
unlock(&dd->zone_lock);
...
__blk_mq_free_request
check restart flag (not set)
-> queue not run
...
if (!rq && have writes)
blk_mq_sched_mark_restart_hctx()
unlock(&dd->lock)
Since the dispatch context finishes after the write request completion
handling, marking the queue as needing a restart is not seen from
__blk_mq_free_request() and blk_mq_sched_restart() not executed leading
to the dispatch stall under 100% write workloads.
Fix this by moving the call to blk_mq_sched_mark_restart_hctx() from
dd_dispatch_request() into dd_finish_request() under the zone lock to
ensure full mutual exclusion between write request dispatch selection
and zone unlock on write request completion.
