|
| - * containing the Public Key of the target certificate (including DSA parameter
|

|
| - * by the validation algorithm. If not successful, an Error pointer is
|
| - * returned.
|

|
| - * PARAMETERS:
|
| - * "state"
|
| - * Address of ForwardBuilderState to be used. Must be non-NULL.
|
| - * "anchor"
|
| - * Address of TrustAnchor to be used. Must be non-NULL.

|
| - * DESCRIPTION:
|
| - *
|
| - * This function traverses the CertStores in the List of CertStores contained
|
| - * in "state", using the certSelector and other parameters contained in
|
| - * "state", to obtain a List of all available Certs that satisfy the criteria.
|
| - * If a CertStore has a cache, "certSelParams" is used both to query the cache
|
| - * and, if an actual CertStore search occurred, to update the cache. (Behavior
|
| - * is undefined if "certSelParams" is different from the parameters that were
|
| - * used to initialize the certSelector in "state".)
|
| - *
|
| - * If a CertStore using non-blocking I/O returns with an indication that I/O is
|
| - * in progress and the checking has not been completed, this function stores
|
| - * platform-dependent information at "pNBIOContext". Otherwise it stores NULL
|
| - * at "pNBIOContext", and state is updated with the results of the search.
|
| - *
|
| - * PARAMETERS:
|
| - * "state"
|
| - * Address of ForwardBuilderState to be used. Must be non-NULL.
|
| - * "certSelParams"
|
| - * Address of ComCertSelParams which were used in creating the current
|
| - * CertSelector, and to be used in querying and updating any caches that
|
| - * may be associated with with the CertStores.
|
| - * "pNBIOContext"
|
| - * Address at which platform-dependent information is returned if request
|
| - * is suspended for non-blocking I/O. Must be non-NULL.
|
| - * "plContext"
|
| - * Platform-specific context pointer.
|
| - * THREAD SAFETY:
|
| - * Thread Safe (see Thread Safety Definitions in Programmer's Guide)
|
| - * RETURNS:
|
| - * Returns NULL if the function succeeds.
|
| - * Returns a Build Error if the function fails in a non-fatal way
|
| - * Returns a Fatal Error if the function fails in an unrecoverable way.

|
| - * FUNCTION: pkix_BuildForwardDepthFirstSearch
|
| - * DESCRIPTION:
|
| - *
|
| - * This function performs a depth first search in the "forward" direction (from
|
| - * the target Cert to the trust anchor). A non-NULL targetCert must be stored
|
| - * in the ForwardBuilderState before this function is called. It is not written
|
| - * recursively since execution may be suspended in in any of several places
|
| - * pending completion of non-blocking I/O. This iterative structure makes it
|
| - * much easier to resume where it left off.
|
| - *
|
| - * Since the nature of the search is recursive, the recursion is handled by
|
| - * chaining states. That is, each new step involves creating a new
|
| - * ForwardBuilderState linked to its predecessor. If a step turns out to be
|
| - * fruitless, the state of the predecessor is restored and the next alternative
|
| - * is tried. When a search is successful, values needed from the last state
|
| - * (canBeCached and validityDate) are copied to the state provided by the
|
| - * caller, so that the caller can retrieve those values.
|
| - *
|
| - * There are three return arguments, the NBIOContext, the ValidateResult and
|
| - * the ForwardBuilderState. If NBIOContext is non-NULL, it means the search is
|
| - * suspended until the results of a non-blocking IO become available. The
|
| - * caller may wait for the completion using platform-dependent methods and then
|
| - * call this function again, allowing it to resume the search. If NBIOContext
|
| - * is NULL and the ValidateResult is non-NULL, it means the search has
|
| - * concluded successfully. If the NBIOContext is NULL but the ValidateResult is
|
| - * NULL, it means the search was unsuccessful.
|
| - *
|
| - * This function performs several steps at each node in the constructed chain:
|
| - *
|
| - * 1) It retrieves Certs from the registered CertStores that match the
|
| - * criteria established by the ForwardBuilderState pointed to by "state", such
|
| - * as a subject name matching the issuer name of the previous Cert. If there
|
| - * are no matching Certs, the function returns to the previous, or "parent",
|
| - * state and tries to continue the chain building with another of the Certs
|
| - * obtained from the CertStores as possible issuers for that parent Cert.
|
| - *
|
| - * 2) For each candidate Cert returned by the CertStores, this function checks
|
| - * whether the Cert is valid. If it is trusted, this function checks whether
|
| - * this Cert might serve as a TrustAnchor for a complete chain.
|
| - *
|
| - * 3) It determines whether this Cert, in conjunction with any of the
|
| - * TrustAnchors, might complete a chain. A complete chain, from this or the
|
| - * preceding step, is checked to see whether it is valid as a complete
|
| - * chain, including the checks that cannot be done in the forward direction.
|
| - *
|
| - * 4) If this Cert chains successfully, but is not a complete chain, that is,
|
| - * we have not reached a trusted Cert, a new ForwardBuilderState is created
|
| - * with this Cert as the immediate predecessor, and we continue in step (1),
|
| - * attempting to get Certs from the CertStores with this Certs "issuer" as
|
| - * their subject.
|
| - *
|
| - * 5) If an entire chain validates successfully, then we are done. A
|
| - * ValidateResult is created containing the Public Key of the target
|
| - * certificate (including DSA parameter inheritance, if any) and the
|
| - * PolicyNode representing the policy tree output by the validation algorithm,
|
| - * and stored at pValResult, and the function exits returning NULL.
|
| - *
|
| - * 5) If the entire chain does not validate successfully, the algorithm
|
| - * discards the latest Cert and continues in step 2 with the next candidate
|
| - * Cert, backing up to a parent state when no more possibilities exist at a
|
| - * given level, and returning failure when we try to back up but discover we
|
| - * are at the top level.
|
| - *
|
| - * PARAMETERS:
|
| - * "pNBIOContext"
|
| - * Address at which platform-dependent information is returned if building
|
| - * is suspended for non-blocking I/O. Must be non-NULL.
|
| - * "pState"
|
| - * Address at which input ForwardBuilderState is found, and at which output
|
| - * ForwardBuilderState is stored. Must be non-NULL.
|
| - * "pValResult"
|
| - * Address at which the ValidateResult is stored. Must be non-NULL.

|
| - *
|
| - * This function initiates the search for a BuildChain, using the parameters
|
| - * provided in "procParams" and, if continuing a search that was suspended
|
| - * for I/O, using the ForwardBuilderState pointed to by "pState".
|
| - *
|
| - * If a successful chain is built, this function stores the BuildResult at
|
| - * "pBuildResult". Alternatively, if an operation using non-blocking I/O
|
| - * is in progress and the operation has not been completed, this function
|
| - * stores the platform-dependent non-blocking I/O context (nbioContext) at
|
| - * "pNBIOContext", the FowardBuilderState at "pState", and NULL at
|
| - * "pBuildResult". Finally, if chain building was unsuccessful, this function
|
| - * stores NULL at both "pState" and at "pBuildResult".
|
| - *
|
| - * Note: This function is re-entered only for the case of non-blocking I/O
|
| - * in the "short-cut" attempt to build a chain using the target Certificate
|
| - * directly with one of the trustAnchors. For all other cases, resumption
|
| - * after non-blocking I/O is via pkix_Build_ResumeBuildChain.
|
| - *
|
| - * PARAMETERS:
|
| - * "procParams"
|
| - * Address of the ProcessingParams for the search. Must be non-NULL.
|
| - * "pNBIOContext"
|
| - * Address at which the NBIOContext is stored indicating whether the
|
| - * validation is complete. Must be non-NULL.
|
| - * "pState"
|
| - * Address at which the ForwardBuilderState is stored, if the chain
|
| - * building is suspended for waiting I/O; also, the address at which the
|
| - * ForwardBuilderState is provided for resumption of the chain building
|
| - * attempt. Must be non-NULL.
|
| - * "pBuildResult"
|
| - * Address at which the BuildResult is stored, after a successful build.
|
| - * Must be non-NULL.
|
| - * "pVerifyNode"
|
| - * Address at which a VerifyNode chain is returned, if non-NULL.

|
| - * FUNCTION: pkix_Build_ResumeBuildChain
|
| - * DESCRIPTION:
|
| - *
|
| - * This function continues the search for a BuildChain, using the parameters
|
| - * provided in "procParams" and the ForwardBuilderState pointed to by "state".
|
| - *
|
| - * If a successful chain is built, this function stores the BuildResult at
|
| - * "pBuildResult". Alternatively, if an operation using non-blocking I/O
|
| - * is in progress and the operation has not been completed, this function
|
| - * stores the FowardBuilderState at "pState" and NULL at "pBuildResult".
|
| - * Finally, if chain building was unsuccessful, this function stores NULL
|
| - * at both "pState" and at "pBuildResult".
|
| - *
|
| - * PARAMETERS:
|
| - * "pNBIOContext"
|
| - * Address at which the NBIOContext is stored indicating whether the
|
| - * validation is complete. Must be non-NULL.
|
| - * "pState"
|
| - * Address at which the ForwardBuilderState is provided for resumption of
|
| - * the chain building attempt; also, the address at which the
|
| - * ForwardBuilderStateis stored, if the chain building is suspended for
|
| - * waiting I/O. Must be non-NULL.
|
| - * "pBuildResult"
|
| - * Address at which the BuildResult is stored, after a successful build.
|
| - * Must be non-NULL.
|
| - * "plContext"
|
| - * Platform-specific context pointer.
|
| - * THREAD SAFETY:
|
| - * Thread Safe (see Thread Safety Definitions in Programmer's Guide)
|
| - * RETURNS:
|
| - * Returns NULL if the function succeeds.
|
| - * Returns a Build Error if the function fails in a non-fatal way
|
| - * Returns a Fatal Error if the function fails in an unrecoverable way.
