2021-02-11cifs: In the new mount api we get the full devname as source=Ronnie Sahlberg
so we no longer need to handle or parse the UNC= and prefixpath= options that mount.cifs are generating. This also fixes a bug in the mount command option where the devname would be truncated into just //server/share because we were looking at the truncated UNC value and not the full path. I.e. in the mount command output the devive //server/share/path would show up as just //server/share Signed-off-by: Ronnie Sahlberg <lsahlber@redhat.com> Reviewed-by: Shyam Prasad N <nspmangalore@gmail.com> Signed-off-by: Steve French <stfrench@microsoft.com>
2021-02-11xfs: consider shutdown in bmapbt cursor delete assertBrian Foster
The assert in xfs_btree_del_cursor() checks that the bmapbt block allocation field has been handled correctly before the cursor is freed. This field is used for accurate calculation of indirect block reservation requirements (for delayed allocations), for example. generic/019 reproduces a scenario where this assert fails because the filesystem has shutdown while in the middle of a bmbt record insertion. This occurs after a bmbt block has been allocated via the cursor but before the higher level bmap function (i.e. xfs_bmap_add_extent_hole_real()) completes and resets the field. Update the assert to accommodate the transient state if the filesystem has shutdown. While here, clean up the indentation and comments in the function.

2021-02-11spi: spi-mem: add spi_mem_dtr_supports_op()Pratyush Yadav
spi_mem_default_supports_op() rejects DTR ops by default to ensure that the controller drivers that haven't been updated with DTR support continue to reject them. It also makes sure that controllers that don't support DTR mode at all (which is most of them at the moment) also reject them. This means that controller drivers that want to support DTR mode can't use spi_mem_default_supports_op(). Driver authors have to roll their own supports_op() function and mimic the buswidth checks. See spi-cadence-quadspi.c for example. Or even worse, driver authors might skip it completely or get it wrong. Add spi_mem_dtr_supports_op(). It provides a basic sanity check for DTR ops and performs the buswidth requirement check. Move the logic for checking buswidth in spi_mem_default_supports_op() to a separate function so the logic is not repeated twice.

2021-02-11dm: fix deadlock when swapping to encrypted deviceMikulas Patocka
The system would deadlock when swapping to a dm-crypt device. The reason is that for each incoming write bio, dm-crypt allocates memory that holds encrypted data. These excessive allocations exhaust all the memory and the result is either deadlock or OOM trigger. This patch limits the number of in-flight swap bios, so that the memory consumed by dm-crypt is limited. The limit is enforced if the target set the "limit_swap_bios" variable and if the bio has REQ_SWAP set. Non-swap bios are not affected becuase taking the semaphore would cause performance degradation. This is similar to request-based drivers - they will also block when the number of requests is over the limit.

2021-02-11dm: add support for passing through inline crypto supportSatya Tangirala
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 encryption settings which all underlying devices support. When a supported setting is used, the bio cloning code handles cloning the crypto context to the bios for all the underlying devices. When an unsupported setting 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.) A DM device's table can only be changed if the "new" inline encryption capabilities are a (*not* necessarily strict) superset of the "old" inline encryption capabilities. Attempts to make changes to the table that result in some inline encryption capability becoming no longer supported will be rejected. For the sake of clarity, key eviction from underlying devices will be handled in a future patch.

2021-02-11block/keyslot-manager: Introduce functions for device mapper supportSatya Tangirala
Introduce blk_ksm_update_capabilities() to update the capabilities of a keyslot manager (ksm) in-place. The pointer to a ksm in a device's request queue may not be easily replaced, because upper layers like the filesystem might access it (e.g. for programming keys/checking capabilities) at the same time the device wants to replace that request queue's ksm (and free the old ksm's memory). This function allows the device to update the capabilities of the ksm in its request queue directly. Devices can safely update the ksm this way without any synchronization with upper layers *only* if the updated (new) ksm continues to support all the crypto capabilities that the old ksm did (see description below for blk_ksm_is_superset() for why this is so). Also introduce blk_ksm_is_superset() which checks whether one ksm's capabilities are a (not necessarily strict) superset of another ksm's. The blk-crypto framework requires that crypto capabilities that were advertised when a bio was created continue to be supported by the device until that bio is ended - in practice this probably means that a device's advertised crypto capabilities can *never* "shrink" (since there's no synchronization between bio creation and when a device may want to change its advertised capabilities) - so a previously advertised crypto capability must always continue to be supported. This function can be used to check that a new ksm is a valid replacement for an old ksm.

2021-02-11block/keyslot-manager: Introduce passthrough keyslot managerSatya Tangirala
The device mapper may map over devices that have inline encryption capabilities, and to make use of those capabilities, the DM device must itself advertise those inline encryption capabilities. One way to do this would be to have the DM device set up a keyslot manager with a "sufficiently large" number of keyslots, but that would use a lot of memory. Also, the DM device itself has no "keyslots", and it doesn't make much sense to talk about "programming a key into a DM device's keyslot manager", so all that extra memory used to represent those keyslots is just wasted. All a DM device really needs to be able to do is advertise the crypto capabilities of the underlying devices in a coherent manner and expose a way to evict keys from the underlying devices. There are also devices with inline encryption hardware that do not have a limited number of keyslots. One can send a raw encryption key along with a bio to these devices (as opposed to typical inline encryption hardware that require users to first program a raw encryption key into a keyslot, and send the index of that keyslot along with the bio). These devices also only need the same things from the keyslot manager that DM devices need - a way to advertise crypto capabilities and potentially a way to expose a function to evict keys from hardware. So we introduce a "passthrough" keyslot manager that provides a way to represent a keyslot manager that doesn't have just a limited number of keyslots, and for which do not require keys to be programmed into keyslots. DM devices can set up a passthrough keyslot manager in their request queues, and advertise appropriate crypto capabilities based on those of the underlying devices. Blk-crypto does not attempt to program keys into any keyslots in the passthrough keyslot manager. Instead, if/when the bio is resubmitted to the underlying device, blk-crypto will try to program the key into the underlying device's keyslot manager.

2021-02-11dm era: only resize metadata in preresumeNikos Tsironis
Metadata resize shouldn't happen in the ctr. The ctr loads a temporary (inactive) table that will only become active upon resume. That is why resize should always be done in terms of resume. Otherwise a load (ctr) whose inactive table never becomes active will incorrectly resize the metadata. Also, perform the resize directly in preresume, instead of using the worker to do it. The worker might run other metadata operations, e.g., it could start digestion, before resizing the metadata. These operations will end up using the old size. This could lead to errors, like: device-mapper: era: metadata_digest_transcribe_writeset: dm_array_set_value failed device-mapper: era: process_old_eras: digest step failed, stopping digestion The reason of the above error is that the worker started the digestion of the archived writeset using the old, larger size. As a result, metadata_digest_transcribe_writeset tried to write beyond the end of the era array.

An endpoint is not a device and it is recommended to use clocks property in the device node. Hence reverting the original change.

2021-02-11ASoC: simple-card-utils: Fix device module clockSameer Pujar
If "clocks = <&xxx>" is specified from the CPU or Codec component device node, the clock is not getting enabled. Thus audio playback or capture fails. Fix this by populating "simple_dai->clk" field when clocks property is specified from device node as well. Also tidy up by re-organising conditional statements of parsing logic.

2021-02-11KVM: x86/xen: Explicitly pad struct compat_vcpu_info to 64 bytesSean Christopherson
Add a 2 byte pad to struct compat_vcpu_info so that the sum size of its fields is actually 64 bytes. The effective size without the padding is also 64 bytes due to the compiler aligning evtchn_pending_sel to a 4-byte boundary, but depending on compiler alignment is subtle and unnecessary. Opportunistically replace spaces with tables in the other fields.
