okay bestie, welcome to Esys_Dicti...kLockReset(3) from the Library Functions Manual — yes, the title is literally that, and the manual name is right there too. This page is your group-chat explainer for the ESAPI function that calls TPM2_DictionaryAttackLockReset. 💅

vibe check: every signature, parameter, return code, and footnote-ish detail is staying exactly as it is — only the voice is glittery. 💖

NAME

Esys_DictionaryAttackLockReset — The ESAPI function for the TPM2_DictionaryAttackLockReset command. 🎀

SYNOPSIS

Functions

okay so here are the three function signatures, bestie — copy them exactly, no autocorrect:

TSS2_RC Esys_DictionaryAttackLockReset_Async (ESYS_CONTEXT *esysContext,
    ESYS_TR lockHandle, ESYS_TR shandle1, ESYS_TR shandle2, ESYS_TR
    shandle3)
TSS2_RC Esys_DictionaryAttackLockReset (ESYS_CONTEXT *esysContext,
    ESYS_TR lockHandle, ESYS_TR shandle1, ESYS_TR shandle2, ESYS_TR
    shandle3)
TSS2_RC Esys_DictionaryAttackLockReset_Finish (ESYS_CONTEXT
    *esysContext)

Detailed Description

ESAPI function to invoke the TPM2_DictionaryAttackLockReset command either as a one-call or in an asynchronous manner. It’s giving two modes: block-and-wait, or send-it-and-finish-later. ✨

Function Documentation

here’s the full tea on each function, bestie — no skipped sections, no missing return codes, fr fr. 🫶

One-Call function: Esys_DictionaryAttackLockReset 🔥

TSS2_RC Esys_DictionaryAttackLockReset (ESYS_CONTEXT * esysContext, ESYS_TR
    lockHandle, ESYS_TR shandle1, ESYS_TR shandle2, ESYS_TR shandle3)

One-Call function for TPM2_DictionaryAttackLockReset

This function invokes the TPM2_DictionaryAttackLockReset command in a one-call variant. This means the function will block until the TPM response is available. All input parameters are const. The memory for non-simple output parameters is allocated by the function implementation. No cap, that’s the whole vibe.

Parameters

  • esysContext — The ESYS_CONTEXT.
  • lockHandle — TPM2_RH_LOCKOUT.
  • shandle1 — Session handle for authorization of lockHandle
  • shandle2 — Second session handle.
  • shandle3 — Third session handle.

Return values

  • TSS2_RC_SUCCESS if the function call was a success.
  • TSS2_ESYS_RC_BAD_REFERENCE if the esysContext or required input pointers or required output handle references are NULL.
  • TSS2_ESYS_RC_BAD_CONTEXT if esysContext corruption is detected.
  • TSS2_ESYS_RC_MEMORY if the ESAPI cannot allocate enough memory for internal operations or return parameters.
  • TSS2_ESYS_RC_BAD_SEQUENCE if the context has an asynchronous operation already pending.
  • TSS2_ESYS_RC_INSUFFICIENT_RESPONSE if the TPM's response does not at least contain the tag, response length, and response code.
  • TSS2_ESYS_RC_MALFORMED_RESPONSE if the TPM's response is corrupted.
  • TSS2_ESYS_RC_RSP_AUTH_FAILED if the response HMAC from the TPM did not verify.
  • TSS2_ESYS_RC_MULTIPLE_DECRYPT_SESSIONS if more than one session has the 'decrypt' attribute bit set.
  • TSS2_ESYS_RC_MULTIPLE_ENCRYPT_SESSIONS if more than one session has the 'encrypt' attribute bit set.
  • TSS2_ESYS_RC_BAD_TR if any of the ESYS_TR objects are unknown to the ESYS_CONTEXT or are of the wrong type or if required ESYS_TR objects are ESYS_TR_NONE.
  • TSS2_ESYS_RC_NO_DECRYPT_PARAM if one of the sessions has the 'decrypt' attribute set and the command does not support encryption of the first command parameter.
  • TSS2_ESYS_RC_NO_ENCRYPT_PARAM if one of the sessions has the 'encrypt' attribute set and the command does not support encryption of the first response parameter.
  • TSS2_RCs produced by lower layers of the software stack may be returned to the caller unaltered unless handled internally.

Asynchronous function: Esys_DictionaryAttackLockReset_Async 🦋

TSS2_RC Esys_DictionaryAttackLockReset_Async (ESYS_CONTEXT * esysContext,
    ESYS_TR lockHandle, ESYS_TR shandle1, ESYS_TR shandle2, ESYS_TR
    shandle3)

Asynchronous function for TPM2_DictionaryAttackLockReset

This function invokes the TPM2_DictionaryAttackLockReset command in an asynchronous variant. This means the function will return as soon as the command has been sent downwards the stack to the TPM. All input parameters are const. In order to retrieve the TPM's response call Esys_DictionaryAttackLockReset_Finish. It’s lowkey the “send it and come back later” main character energy. 🌈

Parameters

  • esysContext — The ESYS_CONTEXT.
  • lockHandle — TPM2_RH_LOCKOUT.
  • shandle1 — Session handle for authorization of lockHandle
  • shandle2 — Second session handle.
  • shandle3 — Third session handle.

Return values

  • ESYS_RC_SUCCESS if the function call was a success.
  • TSS2_ESYS_RC_BAD_REFERENCE if the esysContext or required input pointers or required output handle references are NULL.
  • TSS2_ESYS_RC_BAD_CONTEXT if esysContext corruption is detected.
  • TSS2_ESYS_RC_MEMORY if the ESAPI cannot allocate enough memory for internal operations or return parameters.
  • TSS2_RCs produced by lower layers of the software stack may be returned to the caller unaltered unless handled internally.
  • TSS2_ESYS_RC_MULTIPLE_DECRYPT_SESSIONS if more than one session has the 'decrypt' attribute bit set.
  • TSS2_ESYS_RC_MULTIPLE_ENCRYPT_SESSIONS if more than one session has the 'encrypt' attribute bit set.
  • TSS2_ESYS_RC_BAD_TR if any of the ESYS_TR objects are unknown to the ESYS_CONTEXT or are of the wrong type or if required ESYS_TR objects are ESYS_TR_NONE.
  • TSS2_ESYS_RC_NO_DECRYPT_PARAM if one of the sessions has the 'decrypt' attribute set and the command does not support encryption of the first command parameter.
  • TSS2_ESYS_RC_NO_ENCRYPT_PARAM if one of the sessions has the 'encrypt' attribute set and the command does not support encryption of the first response parameter.

Asynchronous finish function: Esys_DictionaryAttackLockReset_Finish 💜

TSS2_RC Esys_DictionaryAttackLockReset_Finish (ESYS_CONTEXT * esysContext)

Asynchronous finish function for TPM2_DictionaryAttackLockReset

This function returns the results of a TPM2_DictionaryAttackLockReset command invoked via Esys_DictionaryAttackLockReset_Finish. All non-simple output parameters are allocated by the function's implementation. NULL can be passed for every output parameter if the value is not required. This is where the async plotline wraps up, bestie. 🎬

Parameters

  • esysContext — The ESYS_CONTEXT.

Return values

  • TSS2_RC_SUCCESS on success
  • ESYS_RC_SUCCESS if the function call was a success.
  • TSS2_ESYS_RC_BAD_REFERENCE if the esysContext or required input pointers or required output handle references are NULL.
  • TSS2_ESYS_RC_BAD_CONTEXT if esysContext corruption is detected.
  • TSS2_ESYS_RC_MEMORY if the ESAPI cannot allocate enough memory for internal operations or return parameters.
  • TSS2_ESYS_RC_BAD_SEQUENCE if the context has an asynchronous operation already pending.
  • TSS2_ESYS_RC_TRY_AGAIN if the timeout counter expires before the TPM response is received.
  • TSS2_ESYS_RC_INSUFFICIENT_RESPONSE if the TPM's response does not at least contain the tag, response length, and response code.
  • TSS2_ESYS_RC_RSP_AUTH_FAILED if the response HMAC from the TPM did not verify.
  • TSS2_ESYS_RC_MALFORMED_RESPONSE if the TPM's response is corrupted.
  • TSS2_RCs produced by lower layers of the software stack may be returned to the caller unaltered unless handled internally.
