# HG changeset patch # Parent 998cbbaa1896b86db1e1bef17a2cac5cf4e1ca49 Date: Tue, 9 May 2017 14:27:34 -0300 [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.
