[ Upstream commit 5be7a0cef3229fb3b63a07c0d289daf752545424 ]

When Kerberos authentication is used with AES-256 encryption (AES-256-CCM or AES-256-GCM), the SMB3 encryption and decryption keys must be derived using the full session key (Session.FullSessionKey) rather than just the first 16 bytes (Session.SessionKey).

Per MS-SMB2 section 3.2.5.3.1, when Connection.Dialect is "3.1.1" and Connection.CipherId is AES-256-CCM or AES-256-GCM, Session.FullSessionKey must be set to the full cryptographic key from the GSS authentication context. The encryption and decryption key derivation (SMBC2SCipherKey, SMBS2CCipherKey) must use this FullSessionKey as the KDF input. The signing key derivation continues to use Session.SessionKey (first 16 bytes) in all cases.

Previously, generate_key() hardcoded SMB2_NTLMV2_SESSKEY_SIZE (16) as the HMAC-SHA256 key input length for all derivations. When Kerberos with AES-256 provides a 32-byte session key, the KDF for encryption/decryption was using only the first 16 bytes, producing keys that did not match the server's, causing mount failures with sec=krb5 and require_gcm_256=1.

Add a full_key_size parameter to generate_key() and pass the appropriate size from generate_smb3signingkey():
- Signing: always SMB2_NTLMV2_SESSKEY_SIZE (16 bytes)
- Encryption/Decryption: ses->auth_key.len when AES-256, otherwise 16

Also fix cifs_dump_full_key() to report the actual session key length for AES-256 instead of hardcoded CIFS_SESS_KEY_SIZE, so that userspace tools like Wireshark receive the correct key for decryption.

[ Upstream commit 140039c23aca067b9ff0242e3c0ce96276bb95f3 ]

Replace devm_clk_get() followed by clk_prepare_enable() with devm_clk_get_enabled() for the bus clock. This reduces boilerplate code and error handling, as the managed API automatically disables the clock when the device is removed or if probe fails.

Remove the now-unnecessary clk_disable_unprepare() calls from the probe error path and the remove callback. Adjust the error handling to use the existing put_host label.

[ Upstream commit 0f25236694a2854627c1597465a071e6bb6fe572 ]

Make sure to deregister the controller before disabling underlying resources like interrupts during driver unbind.

Note that clocks were also disabled before the recent commit 140039c23aca ("spi: sifive: Simplify clock handling with devm_clk_get_enabled()").
