Hi,
I'm working on a storage backend for libvirt which needs credentials
to access the storage pool. I want to use the build in secret
manager from libvirt, but it seems I do not have access to the
secretDriver in a storage backend?
static int virStorageBackendRBDRefreshPool(virConnectPtr conn
ATTRIBUTE_UNUSED, virStoragePoolObjPtr pool) {
if (pool->def->source.auth.cephx.secret != NULL) {
      virSecretPtr secret;
      secret = conn->secretDriver->lookupByUUID(conn,
pool->def->source.auth.cephx.secret);
      virSecretFree(secret);
  }
return 0;
}
It goes wrong at this point:
conn->secretDriver->lookupByUUID(conn,pool->def->source.auth.cephx.secret);
"error: dereferencing pointer to incomplete type"
Is the secretDriver available in a storage backend? In
storage_backend.c I see that it should be available, correct?
Are you missing the '#include "datatypes.h"'  header ?
Yes, that was indeed the fix.

Although, in the meantime I found:

virSecretPtr secret;
secret = virSecretLookupByUUIDString(conn, 
pool->def->source.auth.cephx.secret);

value = virSecretGetValue(secret, &value_size, 0);

This also works fine, but what do you recommend?
