List the installed host-keys in the sysfs if the machine supports the Query Ultravisor Keys UVC. As of now, two types of host-keys are available: The used/primary host key, and the backup host-key both hastes are available in a sysfs file. For forwards compatibility an `all` file is also available that displays the whole payload (15*32 bytes) and therefore future key hashes. Since v1: * added r-b's from Janoch & Christoph * fixed minor issues (Janosch) * removed an unnecessary UVC availability-check in uv_query_keys -> removed Christoph's r-b from patch 2 Steffen Eiden (2): s390/uv: Refactor uv-sysfs creation s390/uv: Provide host-key hashes in sysfs arch/s390/include/asm/uv.h | 16 ++++++ arch/s390/kernel/uv.c | 105 +++++++++++++++++++++++++++++++++---- 2 files changed, 111 insertions(+), 10 deletions(-) -- 2.43.0
