The sign operation can operate in a non-hashed mode by running the RSA sign operation directly on the input. This assumes that the input is less than key_size_in_bytes - 11. Since the TPM performs its own PKCS1 padding, it isn't possible to support 'raw' mode, only 'pkcs1'. Alternatively, a hashed version is also possible. In this variant the input is hashed (by userspace) via the selected hash function first. Then this implementation takes care of converting the hash to ASN.1 format and the sign operation is performed on the result. This is similar to the implementation inside crypto/rsa-pkcs1pad.c. ASN1 templates were copied from crypto/rsa-pkcs1pad.c. There seems to be no easy way to expose that functionality, but likely the templates should be shared somehow. The sign operation is implemented via TPM_Sign operation on the TPM. It is assumed that the TPM wrapped key provided uses TPM_SS_RSASSAPKCS1v15_DER signature scheme. This allows the TPM_Sign operation to work on data up to key_len_in_bytes - 11 bytes long. In theory, we could also use TPM_Unbind instead of TPM_Sign, but we would have to manually pkcs1 pad the digest first. Signed-off-by:

This patch implements the pkey_decrypt operation using the private key blob. The blob is first loaded into the TPM via tpm_loadkey2. Once the handle is obtained, tpm_unbind operation is used to decrypt the data on the TPM and the result is returned. The key loaded by tpm_loadkey2 is then evicted via tpm_flushspecific operation. This patch assumes that the SRK authorization is a well known 20-byte of zeros and the same holds for the key authorization of the provided key. Signed-off-by:

This patch exposes some common functionality needed to send TPM commands. Several functions from keys/trusted.c are exposed for use by the new tpm key subtype and a module dependency is introduced. In the future, common functionality between the trusted key type and the asym_tpm subtype should be factored out into a common utility library. Signed-off-by:

This commit implements the pkey_query operation. This is accomplished by utilizing the public key portion to obtain max encryption size information for the operations that utilize the public key (encrypt, verify). The private key size extracted from the TPM_Key data structure is used to fill the information where the private key is used (decrypt, sign). The kernel uses a DER/BER format for public keys and does not support setting the key via the raw binary form. To get around this a simple DER/BER formatter is implemented which stores the DER/BER formatted key and exponent in a temporary buffer for use by the crypto API. The only exponent supported currently is 65537. This holds true for other Linux TPM tools such as 'create_tpm_key' and trousers-openssl_tpm_engine. Signed-off-by:

For TPM based keys, the only standard seems to be described here: http://david.woodhou.se/draft-woodhouse-cert-best-practice.html#rfc.section.4.4 Quote from the relevant section: "Rather, a common form of storage for "wrapped" keys is to encode the binary TCPA_KEY structure in a single ASN.1 OCTET-STRING, and store the result in PEM format with the tag "-----BEGIN TSS KEY BLOB-----". " This patch implements the above behavior. It is assumed that the PEM encoding is stripped out by userspace and only the raw DER/BER format is provided. This is similar to how PKCS7, PKCS8 and X.509 keys are handled. Signed-off-by:

Implement the encrypt, decrypt and sign operations for the software asymmetric key subtype. This mostly involves offloading the call to the crypto layer. Note that the decrypt and sign operations require a private key to be supplied. Encrypt (and also verify) will work with either a public or a private key. A public key can be supplied with an X.509 certificate and a private key can be supplied using a PKCS#8 blob: # j=`openssl pkcs8 -in ~/pkcs7/firmwarekey2.priv -topk8 -nocrypt -outform DER | keyctl padd asymmetric foo @s` # keyctl pkey_query $j - enc=pkcs1 key_size=4096 max_data_size=512 max_sig_size=512 max_enc_size=512 max_dec_size=512 encrypt=y decrypt=y sign=y verify=y # keyctl pkey_encrypt $j 0 data enc=pkcs1 >/tmp/enc # keyctl pkey_decrypt $j 0 /tmp/enc enc=pkcs1 >/tmp/dec # cmp data /tmp/dec # keyctl pkey_sign $j 0 data enc=pkcs1 hash=sha1 >/tmp/sig # keyctl pkey_verify $j 0 data /tmp/sig enc=pkcs1 hash=sha1 # Signed-off-by:

Put a flag in the public_key struct to indicate if the structure is holding a private key. The private key must be held ASN.1 encoded in the format specified in RFC 3447 A.1.2. This is the form required by crypto/rsa.c. The software encryption subtype's verification and query functions then need to select the appropriate crypto function to set the key. Signed-off-by:

Provide five keyctl functions that permit userspace to make use of the new key type ops for accessing and driving asymmetric keys. (*) Query an asymmetric key. long keyctl(KEYCTL_PKEY_QUERY, key_serial_t key, unsigned long reserved, struct keyctl_pkey_query *info); Get information about an asymmetric key. The information is returned in the keyctl_pkey_query struct: __u32 supported_ops; A bit mask of flags indicating which ops are supported. This is constructed from a bitwise-OR of: KEYCTL_SUPPORTS_{ENCRYPT,DECRYPT,SIGN,VERIFY} __u32 key_size; The size in bits of the key. __u16 max_data_size; __u16 max_sig_size; __u16 max_enc_size; __u16 max_dec_size; The maximum sizes in bytes of a blob of data to be signed, a signature blob, a blob to be encrypted and a blob to be decrypted. reserved must be set to 0. This is intended for future use to hand over one or more passphrases needed unlock a key. If successful, 0 is returned. If the key is not an asymmetric key, EOPNOTSUPP is returned. (*) Encrypt, decrypt, sign or verify a blob using an asymmetric key. long keyctl(KEYCTL_PKEY_ENCRYPT, const struct keyctl_pkey_params *params, const char *info, const void *in, void *out); long keyctl(KEYCTL_PKEY_DECRYPT, const struct keyctl_pkey_params *params, const char *info, const void *in, void *out); long keyctl(KEYCTL_PKEY_SIGN, const struct keyctl_pkey_params *params, const char *info, const void *in, void *out); long keyctl(KEYCTL_PKEY_VERIFY, const struct keyctl_pkey_params *params, const char *info, const void *in, const void *in2); Use an asymmetric key to perform a public-key cryptographic operation a blob of data. The parameter block pointed to by params contains a number of integer values: __s32 key_id; __u32 in_len; __u32 out_len; __u32 in2_len; For a given operation, the in and out buffers are used as follows: Operation ID in,in_len out,out_len in2,in2_len ======================= =============== =============== =========== KEYCTL_PKEY_ENCRYPT Raw data Encrypted data - KEYCTL_PKEY_DECRYPT Encrypted data Raw data - KEYCTL_PKEY_SIGN Raw data Signature - KEYCTL_PKEY_VERIFY Raw data - Signature info is a string of key=value pairs that supply supplementary information. The __spare space in the parameter block must be set to 0. This is intended, amongst other things, to allow the passing of passphrases required to unlock a key. If successful, encrypt, decrypt and sign all return the amount of data written into the output buffer. Verification returns 0 on success. Signed-off-by: -

Provide five new operations in the key_type struct that can be used to provide access to asymmetric key operations. These will be implemented for the asymmetric key type in a later patch and may refer to a key retained in RAM by the kernel or a key retained in crypto hardware. int (*asym_query)(const struct kernel_pkey_params *params, struct kernel_pkey_query *info); int (*asym_eds_op)(struct kernel_pkey_params *params, const void *in, void *out); int (*asym_verify_signature)(struct kernel_pkey_params *params, const void *in, const void *in2); Since encrypt, decrypt and sign are identical in their interfaces, they're rolled together in the asym_eds_op() operation and there's an operation ID in the params argument to distinguish them. Verify is different in that we supply the data and the signature instead and get an error value (or 0) as the only result on the expectation that this may well be how a hardware crypto device may work.

It's really time to get this into a regression test somewhere so I stop breaking it. Thanks to Zong for resurrecting it again! - Various fixes that resulted from a year old review of our original patch set that I finally got around to. - Various improvements to SMP support, largely based around having switched to logical hart numbering, as well as some interrupt improvements. This one is in the same patch set as above, thanks to Atish for sheparding everything though as my patch set was a bit of a mess. I'm pretty sure this is our largest patch set since the original kernel contribution, and it's certainly the one with the most contributors.

Here are highlights: General: - Appropriate fall-through annotations everywhere - Some code cleanup in memalloc code, handling non-cacahed pages more commonly in the helper - Deployment of SNDRV_PCM_INFO_SYNC_APPLPTR flag consistently Drivers: - More HD-audio CA0132 codec improvement for supporting other Creative boards - Plumbing legacy HD-audio codecs as ASoC BE on Intel SST; this will give move support of existing HD-audio devices with DSP - A few device-specific HD-audio quirks as usual - New quirk for RME CC devices and correction for B&W PX for USB-audio - FireWire: code refactoring including devres usages ASoC Core: - Continued componentization works; it's almost done! - A bunch of new for_each_foo macros - Cleanups and fixes in DAPM code ASoC Drivers: - MCLK support for several different devices, including CS42L51, STM32 SAI, and MAX98373 - Support for Allwinner A64 CODEC analog, Intel boards with DA7219 and MAX98927, Meson AXG PDM inputs, Nuvoton NAU8822, Renesas R8A7744 and TI PCM3060" * tag 'sound-4.20-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/tiwai/sound: (299 commits) ASoC: stm32: sai: fix master clock naming ASoC: stm32: add clock dependency for sai ALSA: hda/ca0132 - Actually fix microphone issue ASoC: sun4i-i2s: move code from startup/shutdown hooks into pm_runtime hooks ASoC: wm2000: Remove wm2000_read helper function ASoC: cs42l51: fix mclk support ASoC: wm_adsp: Log addresses as 8 digits in wm_adsp_buffer_populate ASoC: wm_adsp: Rename memory fields in wm_adsp_buffer ASoC: cs42l51: add mclk support ASoC: stm32: sai: set sai as mclk clock provider ASoC: dt-bindings: add mclk support to cs42l51 ASoC: dt-bindings: add mclk provider support to stm32 sai ASoC: soc-core: fix trivial checkpatch issues ASoC: dapm: Add support for hw_free on CODEC to CODEC links ASoC: Intel: kbl_da7219_max98927: minor white space clean up ALSA: i2c/cs8427: Fix int to char conversion ALSA: doc: Brush up the old writing-an-alsa-driver ASoC: rsnd: tidyup SSICR::SWSP for TDM ASoC: rsnd: enable TDM settings for SSI parent ASoC: pcm3168a: add hw constraint for capture channel ... -

Pull SCSI updates from James Bottomley: "This is mostly updates of the usual drivers: UFS, esp_scsi, NCR5380, qla2xxx, lpfc, libsas, hisi_sas. In addition there's a set of mostly small updates to the target subsystem a set of conversions to the generic DMA API, which do have some potential for issues in the older drivers but we'll handle those as case by case fixes. A new myrs driver for the DAC960/mylex raid controllers to replace the block based DAC960 which is also being removed by Jens in this merge window. Plus the usual slew of trivial changes" [ "myrs" stands for "MYlex Raid Scsi". Obviously. Silly of me to even wonder. There's also a "myrb" driver, where the 'b' stands for 'block'. Truly, somebody has got mad naming skillz. - Linus ] * tag 'scsi-misc' of git://git.kernel.org/pub/scm/linux/kernel/git/jejb/scsi: (237 commits) scsi: myrs: Fix the processor absent message in processor_show() scsi: myrs: Fix a logical vs bitwise bug scsi: hisi_sas: Fix NULL pointer dereference scsi: myrs: fix build failure on 32 bit scsi: fnic: replace gross legacy tag hack with blk-mq hack scsi: mesh: switch to generic DMA API scsi: ips: switch to generic DMA API scsi: smartpqi: fully convert to the generic DMA API scsi: vmw_pscsi: switch to generic DMA API scsi: snic: switch to generic DMA API scsi: qla4xxx: fully convert to the generic DMA API scsi: qla2xxx: fully convert to the generic DMA API scsi: qla1280: switch to generic DMA API scsi: qedi: fully convert to the generic DMA API scsi: qedf: fully convert to the generic DMA API scsi: pm8001: switch to generic DMA API scsi: nsp32: switch to generic DMA API scsi: mvsas: fully convert to the generic DMA API scsi: mvumi: switch to generic DMA API scsi: mpt3sas: switch to generic DMA API ...
