2025-04-03scsi: ufs: exynos: Move phy calls to .exit() callbackPeter Griffin
ufshcd_pltfrm_remove() calls ufshcd_remove(hba) which in turn calls ufshcd_hba_exit(). By moving the phy_power_off() and phy_exit() calls to the newly created .exit callback they get called by ufshcd_variant_hba_exit() before ufshcd_hba_exit() turns off the regulators. This is also similar flow to the ufs-qcom driver.

2025-04-03scsi: ufs: exynos: Ensure consistent phy reference countsPeter Griffin
ufshcd_link_startup() can call ufshcd_vops_link_startup_notify() multiple times when retrying. This causes the phy reference count to keep increasing and the phy to not properly re-initialize. If the phy has already been previously powered on, first issue a phy_power_off() and phy_exit(), before re-initializing and powering on again.

2025-02-20scsi: ufs: qcom: Pass target_freq to clk scale pre and post changeCan Guo
Instead of only two frequencies, if OPP V2 is used, the UFS devfreq clock scaling may scale the clock among multiple frequencies. In the case of scaling up, the devfreq may decide to scale the clock to an intermediate freq based on load, but the clock scale up pre change operation uses settings for the max clock freq unconditionally. Fix it by passing the target_freq to clock scale up pre change so that the correct settings for the target_freq can be used. In the case of scaling down, the clock scale down post change operation is doing fine, because it reads the actual clock rate to tell freq, but to keep symmetry with clock scale up pre change operation, just use the target_freq instead of reading clock rate.

2025-02-20scsi: ufs: core: Pass target_freq to clk_scale_notify() vopCan Guo
Instead of only two frequencies, if OPP V2 is used, the UFS devfreq clock scaling may scale the clock among multiple frequencies, so just passing up/down to vop clk_scale_notify() is not enough to cover the intermediate clock freqs between the min and max freqs. Hence pass the target_freq, which will be used in successive commits, to clk_scale_notify() to allow the vop to perform corresponding configurations with regard to the clock freqs.

2025-02-10blk-crypto: add basic hardware-wrapped key supportEric Biggers
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 raw keys in kernel memory, without limiting the number of keys that can be used. Such hardware also supports deriving a "software secret" for cryptographic tasks that can't be handled by inline encryption; this is needed for fscrypt to work properly. To support this hardware, allow struct blk_crypto_key to represent a hardware-wrapped key as an alternative to a raw 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.

2025-02-03scsi: ufs: qcom: Enable UFS Shared ICE FeatureRam Kumar Dwivedi
By default, the UFS controller allocates a fixed number of RX and TX engines statically. Consequently, when UFS reads are in progress, the TX ICE engines remain idle, and vice versa. This leads to inefficient utilization of RX and TX engines. To address this limitation, enable the UFS shared ICE feature for Qualcomm UFS V5.0 and above. This feature utilizes a pool of crypto cores for both TX streams (UFS Write – Encryption) and RX streams (UFS Read – Decryption). With this approach, crypto cores are dynamically allocated to either the RX or TX stream as needed.

2025-02-03scsi: ufs: core: Fix use-after free in init error and remove pathsAndré Draszik
devm_blk_crypto_profile_init() registers a cleanup handler to run when the associated (platform-) device is being released. For UFS, the crypto private data and pointers are stored as part of the ufs_hba's data structure 'struct ufs_hba::crypto_profile'. This structure is allocated as part of the underlying ufshcd and therefore Scsi_host allocation. During driver release or during error handling in ufshcd_pltfrm_init(), this structure is released as part of ufshcd_dealloc_host() before the (platform-) device associated with the crypto call above is released. Once this device is released, the crypto cleanup code will run, using the just-released 'struct ufs_hba::crypto_profile'. This causes a use-after-free situation: Call trace: kfree+0x60/0x2d8 (P) kvfree+0x44/0x60 blk_crypto_profile_destroy_callback+0x28/0x70 devm_action_release+0x1c/0x30 release_nodes+0x6c/0x108 devres_release_all+0x98/0x100 device_unbind_cleanup+0x20/0x70 really_probe+0x218/0x2d0 In other words, the initialisation code flow is: platform-device probe ufshcd_pltfrm_init() ufshcd_alloc_host() scsi_host_alloc() allocation of struct ufs_hba creation of scsi-host devices devm_blk_crypto_profile_init() devm registration of cleanup handler using platform-device and during error handling of ufshcd_pltfrm_init() or during driver removal: ufshcd_dealloc_host() scsi_host_put() put_device(scsi-host) release of struct ufs_hba put_device(platform-device) crypto cleanup handler To fix this use-after free, change ufshcd_alloc_host() to register a devres action to automatically cleanup the underlying SCSI device on ufshcd destruction, without requiring explicit calls to ufshcd_dealloc_host(). This way: * the crypto profile and all other ufs_hba-owned resources are destroyed before SCSI (as they've been registered after) * a memleak is plugged in tc-dwc-g210-pci.c remove() as a side-effect * EXPORT_SYMBOL_GPL(ufshcd_dealloc_host) can be removed fully as it's not needed anymore * no future drivers using ufshcd_alloc_host() could ever forget adding the cleanup Fixes: cb77cb5abe1f ("blk-crypto: rename blk_keyslot_manager to blk_crypto_profile") Fixes: d76d9d7d1009 ("scsi: ufs: use devm_blk_ksm_init()") Cc: stable@vger.kernel.org Signed-off-by: André Draszik <andre.draszik@linaro.org> Link: https://lore.kernel.org/r/20250124-ufshcd-fix-v4-1-c5d0144aae59@linaro.org Reviewed-by: Bean Huo <beanhuo@micron.com> Reviewed-by: Manivannan Sadhasivam <manivannan.sadhasivam@linaro.org> Acked-by: Eric Biggers <ebiggers@kernel.org> Signed-off-by: Martin K.

2025-01-02scsi: ufs: qcom: Convert to use UFSHCD_QUIRK_CUSTOM_CRYPTO_PROFILEEric Biggers
By default the UFS core is responsible for initializing the blk_crypto_profile, but Qualcomm platforms have their own way of programming and evicting crypto keys. So currently ufs_hba_variant_ops::program_key is used to redirect control flow from ufshcd_program_key(). This has worked until now, but it's a bit of a hack, given that the key (and algorithm ID etc.) ends up being converted from blk_crypto_key => ufs_crypto_cfg_entry => SCM call parameters, where the intermediate ufs_crypto_cfg_entry step is unnecessary. Taking a similar approach with the upcoming wrapped key support, the implementation of which is similarly platform-specific, would require adding four new methods to ufs_hba_variant_ops, changing program_key to take the struct blk_crypto_key, and adding a new UFSHCD_CAP_* flag to indicate support for wrapped keys. This patch takes a different approach. It changes ufs-qcom to use the existing UFSHCD_QUIRK_CUSTOM_CRYPTO_PROFILE which was recently added for ufs-exynos. This allows it to override the full blk_crypto_profile, eliminating the need for the existing ufs_hba_variant_ops::program_key and the hooks that would have been needed for wrapped key support. It does require a bit of duplicated code to read the crypto capability registers, but it's worth the simplification in design with ufs-qcom and ufs-exynos now using the same method to customize the crypto profile, and it makes it much easier to add wrapped key support.

2025-01-02scsi: ufs: qcom: Power down the controller/device during system suspend for ↵Manivannan Sadhasivam
SM8550/SM8650 SoCs SM8550 and SM8650 SoCs doesn't support UFS PHY retention. So once these SoCs reaches the low power state (CX power collapse) during system suspend, all the PHY hardware state gets lost. This leads to the UFS resume failure: ufshcd-qcom 1d84000.ufs: ufshcd_uic_hibern8_exit: hibern8 exit failed. ret = 5 ufshcd-qcom 1d84000.ufs: __ufshcd_wl_resume: hibern8 exit failed 5 ufs_device_wlun 0:0:0:49488: ufshcd_wl_resume failed: 5 ufs_device_wlun 0:0:0:49488: PM: dpm_run_callback(): scsi_bus_resume+0x0/0x84 returns 5 ufs_device_wlun 0:0:0:49488: PM: failed to resume async: error 5 With the default system suspend level of UFS_PM_LVL_3, the power domain for UFS PHY needs to be kept always ON to retain the state. But this would prevent these SoCs from reaching the CX power collapse state, leading to poor power saving during system suspend. So to fix this issue without affecting the power saving, set 'ufs_qcom_drvdata::no_phy_retention' to true which sets 'hba->spm_lvl' to UFS_PM_LVL_5 to allow both the controller and device (in turn the PHY) to be powered down during system suspend for these SoCs by default.

ufs_qcom_power_up_sequence() PHY might already be powered on during ufs_qcom_power_up_sequence() in a couple of cases: 1. During UFSHCD_QUIRK_REINIT_AFTER_MAX_GEAR_SWITCH quirk 2. Resuming from spm_lvl = 5 suspend In those cases, it is necessary to call phy_power_off() and phy_exit() in ufs_qcom_power_up_sequence() function to power off the PHY before calling phy_init() and phy_power_on(). Case (1) is doing it via ufs_qcom_reinit_notify() callback, but case (2) is not handled. So to satisfy both cases, call phy_power_off() and phy_exit() if the phy_count is non-zero. And with this change, the reinit_notify() callback is no longer needed.

Some early UFSHCI 4.0 controllers support the UFSHCI 3.0 register set. The UFSHCD_QUIRK_BROKEN_LSDBS_CAP quirk must be set for these controllers. Commit b92e5937e352 ("scsi: ufs: core: Move code out of an if-statement") changed the behavior for these controllers from working fine into "ufshcd_add_scsi_host: failed to initialize (legacy doorbell mode not supported)". Fix this by setting the "broken LSDBS" quirk for the SM8650 development board.
