[PATCH 0/3] Allow syscalls for openssl engines
From: Eduardo Barretto <ebarretto@linux.vnet.ibm.com>
To: openssh-unix-dev@mindrot.org
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.

The EP11 crypto card also needs to make an ioctl call, which receives an
specific argument.
