=head1 DESCRIPTION
|
|
|
|
OSSL_CMP_SRV_process_request() implements the generic aspects of a CMP server.
|
|
Its arguments are the B<OSSL_CMP_SRV_CTX> I<srv_ctx> and the CMP request message
|
|
I<req>. It does the typical generic checks on I<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
|
|
I<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 L<OSSL_CMP_MSG_http_perform(3)>.
|
|
The B<OSSL_CMP_SRV_CTX> must be set as I<transfer_cb_arg> of I<client_ctx>.
|
|
|
|
OSSL_CMP_SRV_CTX_new() creates and initializes an B<OSSL_CMP_SRV_CTX> structure
|
|
associated with the library context I<libctx> and property query string
|
|
I<propq>, both of which may be NULL to select the defaults.
|
|
|
|
OSSL_CMP_SRV_CTX_free() deletes the given I<srv_ctx>.
|
|
|
|
OSSL_CMP_SRV_CTX_init() sets in the given I<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 I<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 I<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 I<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 I<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 B<OSSL_CMP_CTX> from the I<srv_ctx>.
|
|
|
|
OSSL_CMP_SRV_CTX_get0_custom_ctx() returns the custom server context from
|
|
I<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.
|
|
|
|
=head1 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).
|
|
|
|
=head1 RETURN VALUES
|
|
|
|
OSSL_CMP_SRV_CTX_new() returns a B<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 B<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.
|
|
|
|
=head1 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.
