+=head1 NAME
+
+fips_module_indicators - Red Hat OpenSSL FIPS module indicators guide
+
+=head1 DESCRIPTION
+
+This guide documents how the Red Hat Enterprise Linux 9 OpenSSL FIPS provider
+implements Approved Security Service Indicators according to the FIPS 140-3
+Implementation Guidelines, section 2.4.C. See
+L<https://csrc.nist.gov/CSRC/media/Projects/cryptographic-module-validation-program/documents/fips%20140-3/FIPS%20140-3%20IG.pdf>
+for the FIPS 140-3 Implementation Guidelines.
+
+For all approved services except signatures, the Red Hat OpenSSL FIPS provider
+uses the return code as the indicator as understood by FIPS 140-3. That means
+that every operation that succeeds denotes use of an approved security service.
+Operations that do not succeed may not have been approved security services, or
+may have been used incorrectly.
+
+For signatures, an explicit indicator API is available to determine whether
+a selected operation is an approved security service, in combination with the
+return code of the operation. For a signature operation to be approved, the
+explicit indicator must claim it as approved, and it must succeed.
+
+=head2 Querying the explicit indicator
+
+The Red Hat OpenSSL FIPS provider exports a symbol named
+I<redhat_ossl_query_fipsindicator> that provides information on which signature
+operations are approved security functions. To use this function, either link
+against I<fips.so> directly, or load it at runtime using dlopen(3) and
+dlsym(3).
+
+ #include <openssl/core_dispatch.h>
+ #include "providers/fips/indicator.h"
+
+ void *provider = dlopen("/usr/lib64/ossl-modules/fips.so", RTLD_LAZY);
+ if (provider == NULL) {
+ fprintf(stderr, "%s\n", dlerror());
+ // handle error
+ }
+
+ const OSSL_RH_FIPSINDICATOR_ALORITHM *(*redhat_ossl_query_fipsindicator)(int) \
+ = dlsym(provider, "redhat_ossl_query_fipsindicator");
+ if (redhat_ossl_query_fipsindicator == NULL) {
+ fprintf(stderr, "%s\n", dlerror());
+ fprintf(stderr, "Does your copy of fips.so have the required Red Hat"
+ " patches?\n");
+ // handle error
+ }
+
+Note that this uses the I<providers/fips/indicator.h> header, which is not
+public. Install the I<openssl-debugsource> package from the I<BaseOS-debuginfo>
+repository using I<dnf debuginfo-install openssl> and include
+I</usr/src/debug/openssl-3.*/> in the compiler's include path.
+
+I<redhat_ossl_query_fipsindicator> expects an operation ID as its only
+argument. Currently, the only supported operation ID is I<OSSL_OP_SIGNATURE> to
+obtain the indicators for signature operations. On success, the return value is
+a pointer to an array of I<OSSL_RH_FIPSINDICATOR_STRUCT>s. On failure, NULL is
+returned. The last entry in the array is indicated by I<algorithm_names> being
+NULL.
+
+ typedef struct ossl_rh_fipsindicator_algorithm_st {
+ const char *algorithm_names; /* key */
+ const char *property_definition; /* key */
+ const OSSL_RH_FIPSINDICATOR_DISPATCH *indicators;
+ } OSSL_RH_FIPSINDICATOR_ALGORITHM;
+
+ typedef struct ossl_rh_fipsindicator_dispatch_st {
+ int function_id;
+ int approved;
+ } OSSL_RH_FIPSINDICATOR_DISPATCH;
+
+The I<algorithm_names> field is a colon-separated list of algorithm names from
+one of the I<PROV_NAMES_...> constants, e.g., I<PROV_NAMES_RSA>. strtok(3) can
+be used to locate the appropriate entry. See the example below, where
+I<algorithm> contains the algorithm name to search for:
+
+ const OSSL_RH_FIPSINDICATOR_DISPATCH *indicator_dispatch = NULL;
+ const OSSL_RH_FIPSINDICATOR_ALGORITHM *indicator =
+ redhat_ossl_query_fipsindicator(operation_id);
+ if (indicator == NULL) {
+ fprintf(stderr, "No indicator for operation, probably using implicit"
+ " indicators.\n");
+ // handle error
+ }
+
+ for (; indicator->algorithm_names != NULL; ++indicator) {
+ char *algorithm_names = strdup(indicator->algorithm_names);
+ if (algorithm_names == NULL) {
+ perror("strdup(3)");
+ // handle error
+ }
+
+ const char *algorithm_name = strtok(algorithm_names, ":");
+ for (; algorithm_name != NULL; algorithm_name = strtok(NULL, ":")) {
+ if (strcasecmp(algorithm_name, algorithm) == 0) {
+ indicator_dispatch = indicator->indicators;
+ free(algorithm_names);
+ algorithm_names = NULL;
+ break;
+ }
+ }
+ free(algorithm_names);
+ }
+ if (indicator_dispatch == NULL) {
+ fprintf(stderr, "No indicator for algorithm %s.\n", algorithm);
+ // handle error
+ }
+
+If an appropriate I<OSSL_RH_FIPSINDICATOR_DISPATCH> array is available for the
+given algorithm name, it maps function IDs to their approval status. The last
+entry is indicated by a zero I<function_id>. I<approved> is
+I<OSSL_RH_FIPSINDICATOR_APPROVED> if the operation is an approved security
+service, or part of an approved security service, or
+I<OSSL_RH_FIPSINDICATOR_UNAPPROVED> otherwise. Any other value is invalid.
+Function IDs are I<OSSL_FUNC_*> constants from I<openssl/core_dispatch.h>,
+e.g., I<OSSL_FUNC_SIGNATURE_DIGEST_SIGN_UPDATE> or I<OSSL_FUNC_SIGNATURE_SIGN>.
+
+Assuming I<function_id> is the function in question, the following code can be
+used to query the approval status:
+
+ for (; indicator_dispatch->function_id != 0; ++indicator_dispatch) {
+ if (indicator_dispatch->function_id == function_id) {
+ switch (indicator_dispatch->approved) {
+ case OSSL_RH_FIPSINDICATOR_APPROVED:
+ // approved security service
+ break;
+ case OSSL_RH_FIPSINDICATOR_UNAPPROVED:
+ // unapproved security service
+ break;
+ default:
+ // invalid result
+ break;
+ }
+ break;
+ }
+ }
