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.

The EP11 crypto card needs to make an ioctl call, which receives an
|
|
specific argument. This crypto card is for s390 only.
