Date: Fri, 24 May 2019 10:11:15 +0200
|
||||
Subject: [PATCH] allow s390 specific ioctl for ecc hardware support
|
||||
|
||||
Adding another s390 specific ioctl to be able to support ECC hardware acceleration
|
||||
to the sandbox seccomp filter rules.
|
||||
|
||||
Now the ibmca openssl engine provides elliptic curve cryptography support with the
|
||||
help of libica and CCA crypto cards. This is done via jet another ioctl call to the zcrypt
|
||||
device driver and so there is a need to enable this on the openssl sandbox.
|
||||
|
||||
Code is s390 specific and has been tested, verified and reviewed.
|
||||
|
||||
Please note that I am also the originator of the previous changes in that area.
|
||||
I posted these changes to Eduardo and he forwarded the patches to the openssl
|
||||
community.

Subject: [PATCH] upstream: support PKCS8 as an optional format for storage of
|
||||
|
||||
private keys, enabled via "ssh-keygen -m PKCS8" on operations that save
|
||||
private keys to disk.
|
||||
|
||||
The OpenSSH native key format remains the default, but PKCS8 is a
|
||||
superior format to PEM if interoperability with non-OpenSSH software
|
||||
is required, as it may use a less terrible KDF (IIRC PEM uses a single
|
||||
round of MD5 as a KDF).
