| In order to use the OpenSSL-ibmpkcs11 engine it is needed to allow flock |
| and ipc calls, because this engine calls OpenCryptoki (a PKCS#11 |
| implementation) which calls the libraries that will communicate with the |
| crypto cards. OpenCryptoki makes use of flock and ipc and, as of now, |
| this is only need on s390 architecture. |

| getuid and geteuid are needed when using an openssl engine that calls a |
| crypto card, e.g. ICA (libica). |
| Those syscalls are also needed by the distros for audit code. |
