3.1.4.26 RRPC_FWDeleteAllCryptoSets (Opnum 25)

The RRPC_FWDeleteAllCryptoSets method requests the server to delete all the cryptographic sets of a specific IPsec phase in the policy contained in the policy store that is referenced by the handle specified in the hPolicy parameter.

 unsigned long RRPC_FWDeleteAllCryptoSets(
   [in] FW_CONN_HANDLE rpcConnHandle,
   [in] FW_POLICY_STORE_HANDLE hPolicy,
   [in, range(FW_IPSEC_PHASE_INVALID+1, FW_IPSEC_PHASE_MAX-1)] 
     FW_IPSEC_PHASE IpSecPhase
 );

rpcConnHandle: This parameter is an RPC binding handle that connects to the RPC interface of the Firewall and Advanced Security Protocol.

hPolicy: This input parameter is an FW_POLICY_STORE_HANDLE data type. The data type MUST contain an opened policy store handle that is successfully opened by using the RRPC_FWOpenPolicyStore (Opnum 0) method. The handle MUST have read/write access rights.

IpSecPhase: This parameter specifies the IPsec negotiation phase type in which this set is used.

Return Values: The method returns 0 if successful; if it fails, it returns a nonzero error code. The field can take any specific error code value, as specified in [MS-ERREF]. The following return values are common.

Return value/code	Description
0x00000962 ERROR_ACTIVE_CONNECTIONS	There are nonprimary sets still being referenced by connection security or main mode rules. There is always a primary set to use, either from other stores or a hard-coded one; therefore, this failure never occurs because of primary sets.
0x00000032 ERROR_NOT_SUPPORTED	The specified store does not support this method; the store might be read-only.
0x00000005 ERROR_ACCESS_DENIED	The hPolicy handle was not opened with read/write access rights. The error is also returned if the client does not have the required credentials to call the method.
0x00000057 ERROR_INVALID_PARAMETER	The specified IPsec phase is not a valid one.

Exceptions Thrown: No exceptions are thrown except those that are thrown by the underlying RPC protocol, as specified in [MS-RPCE]. If any lower-layer errors are reported by RPC exception, this exception is converted to an error code and reported to higher-layer protocols via the return value.

This method deletes all the cryptographic sets in the cryptographic linked list of the memory representation of the store being modified. It also writes through and deletes the sets from disk. If called on an online store, the method does not delete the sets if any nonprimary set is referenced by a connection security rule.

The server MUST determine whether the local computer is operating in common criteria mode by invoking the abstract interface IsComputerInCommonCriteriaMode (section 3.1.6.5). If the local computer is operating in common criteria mode, the server MUST fail the operation and return an error of ERROR_ACCESS_DENIED (5). Otherwise, the server MUST validate that the client is authorized to perform the requested operation (as defined in section 3.1.4) before executing this method.
