This patchset allow syscalls (flock, ipc, getuid, geteuid and ioctl), so openssl engines, e.g. OpenSSL-ibmca and OpenSSL-ibmpkcs11, can work and communicate with the crypto cards during ssh login. 1. The flock and ipc are allowed only for s390 architecture. They are needed for openCryptoki project (PKCS#11 implementation), as the ibmpkcs11 engine makes use of openCryptoki. For more information,

...check the openssl engine code, it use ioctl on /dev/crypto.
