|
||||
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).
|
||||
|
||||
adapted from patch by Jakub Jelen via bz3013; ok markus

+1.9 transport: strict key exchange extension
|
||||
+
|
||||
+OpenSSH supports a number of transport-layer hardening measures under
|
||||
+a "strict KEX" feature. This feature is signalled similarly to the
|
||||
+RFC8308 ext-info feature: by including a additional algorithm in the
|
||||
+initiial SSH2_MSG_KEXINIT kex_algorithms field. The client may append
|
||||
+"kex-strict-c-v00@openssh.com" to its kex_algorithms and the server
|
||||
+may append "kex-strict-s-v00@openssh.com". These pseudo-algorithms
|
||||
+are only valid in the initial SSH2_MSG_KEXINIT and MUST be ignored
|
||||
+if they are present in subsequent SSH2_MSG_KEXINIT packets.
|
||||
+
|
||||
+When an endpoint that supports this extension observes this algorithm
|
||||
+name in a peer's KEXINIT packet, it MUST make the following changes to
|
||||
+the the protocol:
|
||||
+
|
||||
+a) During initial KEX, terminate the connection if any unexpected or
|
||||
+ out-of-sequence packet is received. This includes terminating the
|
||||
+ connection if the first packet received is not SSH2_MSG_KEXINIT.
|
||||
+ Unexpected packets for the purpose of strict KEX include messages
|
||||
+ that are otherwise valid at any time during the connection such as
|
||||
+ SSH2_MSG_DEBUG and SSH2_MSG_IGNORE.
|
||||
+b) After sending or receiving a SSH2_MSG_NEWKEYS message, reset the
|
||||
+ packet sequence number to zero. This behaviour persists for the
|
||||
+ duration of the connection (i.e. not just the first
|
||||
+ SSH2_MSG_NEWKEYS).

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.
