tpm: ibmvtpm: Call tpm2_sessions_init() to initialize session support

2024-08-27T18:11:44Z

Commit d2add27cf2b8 ("tpm: Add NULL primary creation") introduced CONFIG_TCG_TPM2_HMAC. When this option is enabled on ppc64 then the following message appears in the kernel log due to a missing call to tpm2_sessions_init(). [ 2.654549] tpm tpm0: auth session is not active Add the missing call to tpm2_session_init() to the ibmvtpm driver to resolve this issue.

tpm: Use auth only after NULL check in tpm_buf_check_hmac_response()

2024-07-16T10:55:58Z

Dereference auth after NULL check in tpm_buf_check_hmac_response(). Otherwise, unless tpm2_sessions_init() was called, a call can cause NULL dereference, when TCG_TPM2_HMAC is enabled.

Unless tpm_chip_bootstrap() was called by the driver, !chip->auth can cause a null derefence in tpm_buf_hmac_session*(). Thus, address !chip->auth in tpm_buf_hmac_session*() and remove the fallback implementation for !TCG_TPM2_HMAC.

tpm_tis_spi: add missing attpm20p SPI device ID entry

2024-07-01T15:50:02Z

"atmel,attpm20p" DT compatible is missing its SPI device ID entry, not allowing module autoloading and leading to the following message: "SPI driver tpm_tis_spi has no spi_device_id for atmel,attpm20p" Based on: commit 7eba41fe8c7b ("tpm_tis_spi: Add missing SPI ID") Fix this by adding the corresponding "attpm20p" spi_device_id entry.

char: tpm: Fix possible memory leak in tpm_bios_measurements_open()

2024-07-01T15:50:02Z

In tpm_bios_measurements_open(), get_device() is called on the device embedded in struct tpm_chip. In the error path, however, put_device() is not called. This results in a reference count leak, which prevents the device from being properly released. This commit makes sure to call put_device() when the seq_open() call fails.
