BACKPORT: FROMLIST: Update Inline Encryption from v5 to v6 of patch series
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 Bug: 137270441 Test: refer to I26376479ee38259b8c35732cb3a1d7e15f9b05a3 Change-Id: I13e2e327e0b4784b394cb1e7cf32a04856d95f01 Link: https://lore.kernel.org/linux-block/20191218145136.172774-1-satyat@google.com/ Signed-off-by: Satya Tangirala <satyat@google.com> |

If __blk_rq_map_user_iov() is failed in blk_rq_map_user_iov(),
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().

block: set the zone size in blk_revalidate_disk_zones atomically
The current zone revalidation code has a major problem in that it doesn't update the zone size and q->nr_zones atomically, leading to a short window where an out of bounds access to the zone arrays is possible. To fix this move the setting of the zone size into the crticial sections blk_revalidate_disk_zones so that it gets updated together with the zone bitmaps and q->nr_zones. This also slightly simplifies the caller as it deducts the zone size from the report_zones. This change also allows to check for a power of two zone size in generic code.

block: Remove partition support for zoned block devices
No known partitioning tool supports zoned block devices, especially the host managed flavor with strong sequential write constraints. Furthermore, there are also no known user nor use cases for partitioned zoned block devices. This patch removes partition device creation for zoned block devices, which allows simplifying the processing of zone commands for zoned block devices. A warning is added if a partition table is found on the device. For report zones operations no zone sector information remapping is necessary anymore, simplifying the code. Of note is that remapping of zone reports for DM targets is still necessary as done by dm_remap_zone_report(). Similarly, remaping of a zone reset bio is not necessary anymore. Testing for the applicability of the zone reset all request also becomes simpler and only needs to check that the number of sectors of the requested zone range is equal to the disk capacity.

block: Simplify report zones execution
All kernel users of blkdev_report_zones() as well as applications use through ioctl(BLKZONEREPORT) expect to potentially get less zone descriptors than requested. As such, the use of the internal report zones command execution loop implemented by blk_report_zones() is not necessary and can even be harmful to performance by causing the execution of inefficient small zones report command to service the reminder of a requested zone array.

block: Enhance blk_revalidate_disk_zones()
For ZBC and ZAC zoned devices, the scsi driver revalidation processing implemented by sd_revalidate_disk() includes a call to sd_zbc_read_zones() which executes a full disk zone report used to check that all zones of the disk are the same size. This processing is followed by a call to blk_revalidate_disk_zones(), used to initialize the device request queue zone bitmaps (zone type and zone write lock bitmaps). To do so, blk_revalidate_disk_zones() also executes a full device zone report to obtain zone types. As a result, the entire zoned block device revalidation process includes two full device zone report. By moving the zone size checks into blk_revalidate_disk_zones(), this process can be optimized to a single full device zone report, leading to shorter device scan and revalidation times. This patch implements this optimization, reducing the original full device zone report implemented in sd_zbc_check_zones() to a single, small, report zones command execution to obtain the size of the first zone of the device. Checks whether all zones of the device are the same size as the first zone size are moved to the generic blk_check_zone() function called from blk_revalidate_disk_zones(). This optimization also has the following benefits: 1) fewer memory allocations in the scsi layer during disk revalidation as the potentailly large buffer for zone report execution is not needed. 2) Implement zone checks in a generic manner, reducing the burden on device driver which only need to obtain the zone size and check that this size is a power of 2 number of LBAs. Any new type of zoned block device will benefit from this.

block: add zone open, close and finish operations
Zoned block devices (ZBC and ZAC devices) allow an explicit control over the condition (state) of zones. The operations allowed are: * Open a zone: Transition to open condition to indicate that a zone will actively be written * Close a zone: Transition to closed condition to release the drive resources used for writing to a zone * Finish a zone: Transition an open or closed zone to the full condition to prevent write operations To enable this control for in-kernel zoned block device users, define the new request operations REQ_OP_ZONE_OPEN, REQ_OP_ZONE_CLOSE and REQ_OP_ZONE_FINISH as well as the generic function blkdev_zone_mgmt() for submitting these operations on a range of zones. This results in blkdev_reset_zones() removal and replacement with this new zone magement function. Users of blkdev_reset_zones() (f2fs and dm-zoned) are updated accordingly.

iocost: over-budget forced IOs should schedule async delay
commit d7bd15a138aef3be227818aad9c501e43c89c8c5 upstream.
When over-budget IOs are force-issued through root cgroup,
iocg_kick_delay() adjusts the async delay accordingly but doesn't
actually schedule async throttle for the issuing task. This bug is
pretty well masked because sooner or later the offending threads are
gonna get directly throttled on regular IOs or have async delay
scheduled by mem_cgroup_throttle_swaprate().
However, it can affect control quality on filesystem metadata heavy
operations. Let's fix it by invoking blkcg_schedule_throttle() when
iocg_kick_delay() says async delay is needed.

blk-mq: make sure that line break can be printed
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.

blk-mq: avoid sysfs buffer overflow with too many CPU cores
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.

blkcg: make blkcg_print_stat() print stats only for online blkgs
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.

iocost: don't nest spin_lock_irq in ioc_weight_write()
This code causes a static analysis warning:
block/blk-iocost.c:2113 ioc_weight_write() error: double lock 'irq'
We disable IRQs in blkg_conf_prep() and re-enable them in
blkg_conf_finish(). IRQ disable/enable should not be nested because
that means the IRQs will be enabled at the first unlock instead of the
second one.

FROMLIST: block: blk-crypto for Inline Encryption
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.

ANDROID: block: Fix bio_crypt_should_process WARN_ON
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).

FROMLIST: block: Add encryption context to struct bio
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.

FROMLIST: block: Keyslot Manager for Inline Encryption
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.

blk-rq-qos: fix first node deletion of rq_qos_del()
rq_qos_del() incorrectly assigns the node being deleted to the head if
it was the first on the list in the !prev path. Fix it by iterating
with ** instead.

block: Fix elv_support_iosched()
A BIO based request queue does not have a tag_set, which prevent testing for the flag BLK_MQ_F_NO_SCHED indicating that the queue does not require an elevator. This leads to an incorrect initialization of a default elevator in some cases such as BIO based null_blk (queue_mode == BIO) with zoned mode enabled as the default elevator in this case is mq-deadline instead of "none". Fix this by testing for a NULL queue mq_ops field which indicates that the queue is BIO based and should not have an elevator.

blk-wbt: fix performance regression in wbt scale_up/scale_down
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.
