DESCRIPTION
OSSL_CMP_SRV_process_request() implements the generic aspects of a CMP
server. Its arguments are the OSSL_CMP_SRV_CTX srv_ctx and the CMP
request message req. It does the typical generic checks on req, calls
the respective callback function (if present) for more specific
processing, and then assembles a result message, which may be a CMP
error message. If after return of the function the expression
OSSL_CMP_CTX_get_status(OSSL_CMP_SRV_CTX_get0_cmp_ctx(srv_ctx)) yields
-1 then the function has closed the current transaction, which may be
due to normal successful end of the transaction or due to an error.
OSSL_CMP_CTX_server_perform() is an interface to
OSSL_CMP_SRV_process_request() that can be used by a CMP client in the
same way as OSSL_CMP_MSG_http_perform(3). The OSSL_CMP_SRV_CTX must be
set as transfer_cb_arg of client_ctx.
OSSL_CMP_SRV_CTX_new(3) creates and initializes an OSSL_CMP_SRV_CTX
structure associated with the library context libctx and property query
string propq, both of which may be NULL to select the defaults.
OSSL_CMP_SRV_CTX_free() deletes the given srv_ctx. If the argument is
NULL, nothing is done.
OSSL_CMP_SRV_CTX_init() sets in the given srv_ctx a custom server
context pointer as well as callback functions performing the specific
processing of CMP certificate requests, revocation requests,
certificate confirmation requests, general messages, error messages,
and poll requests. All arguments except srv_ctx may be NULL. If a
callback for some message type is not given this means that the
respective type of CMP message is not supported by the server.
OSSL_CMP_SRV_CTX_init_trans() sets in srv_ctx the optional callback
functions for initiating delayed delivery and cleaning up a
transaction. If the <delay> function is NULL then delivery of
responses is never delayed. Otherwise delay takes a custom server
context and a request message as input. It must return 1 if delivery
of the respective response shall be delayed, 0 if not, and -1 on error.
If the <clean> function is NULL then no specific cleanup is performed.
Otherwise clean takes a custom server context and a transaction ID
pointer as input, where the pointer is NULL in case a new transaction
is being started and otherwise provides the ID of the transaction being
terminated. The <clean> function should reset the respective portions
of the state and free related memory. It must return 1 on success and
0 on error.
OSSL_CMP_SRV_CTX_get0_cmp_ctx() returns the OSSL_CMP_CTX from the
srv_ctx.
OSSL_CMP_SRV_CTX_get0_custom_ctx() returns the custom server context
from srv_ctx that has been set using OSSL_CMP_SRV_CTX_init().
OSSL_CMP_SRV_CTX_set_send_unprotected_errors() enables sending error
messages and other forms of negative responses unprotected.
OSSL_CMP_SRV_CTX_set_accept_unprotected() enables acceptance of
requests without protection of with invalid protection.
OSSL_CMP_SRV_CTX_set_accept_raverified() enables acceptance of
ir/cr/kur messages with POPO 'RAVerified'.
OSSL_CMP_SRV_CTX_set_grant_implicit_confirm() enables granting implicit
confirmation of newly enrolled certificates if requested.
NOTES
CMP is defined in RFC 4210 (and CRMF in RFC 4211).
So far the CMP server implementation is limited to one request per CMP
message (and consequently to at most one response component per CMP
message).
RETURN VALUES
OSSL_CMP_SRV_CTX_new(3) returns a OSSL_CMP_SRV_CTX structure on success,
NULL on error.
OSSL_CMP_SRV_CTX_free() does not return a value.
OSSL_CMP_SRV_CTX_get0_cmp_ctx() returns a OSSL_CMP_CTX structure on
success, NULL on error.
OSSL_CMP_SRV_CTX_get0_custom_ctx() returns the custom server context
that has been set using OSSL_CMP_SRV_CTX_init().
All other functions return 1 on success, 0 on error.
HISTORY
The OpenSSL CMP support was added in OpenSSL 3.0.
OSSL_CMP_SRV_CTX_init_trans() supporting delayed delivery of all types
of response messages was added in OpenSSL 3.3.
