TLS subsystem (TLS engine + tlsops module) was extended with functions to reload CA + CRL lists on-the-fly for all configured domains.
TLSOPS module was extended to provide a new MI command "refresh_crl_ca", calling refresh of CRL and CA files. New connections will be validated with the newly loaded CA + CRLs.
Previously, OpenSIPS does not reload CA list when running. The same holds for CRL in 2.x branch.
Reloading CRL is of high importance as OpenSIPS can be running several weeks/months without being restarted. If TLS with client certificates is used it is crucial to periodically refresh CRL files and to reload them by OpenSIPS without need to restart it.
