This is an automated email from the git hooks/post-receive script.
djm pushed a commit to branch master
in repository openssh.
commit 1195f4cb07ef4b0405c839293c38600b3e9bdb46
Author: djm at openbsd.org <djm at openbsd.org>
Date: Thu Jan 8 10:14:08 2015 +0000
upstream commit
deprecate key_load_private_pem() and
sshkey_load_private_pem() interfaces. Refactor the generic key loading API to
not require pathnames to be specified (they weren't really used).
Fixes a few other things en passant:
Makes ed25519 keys work for hostbased authentication (ssh-keysign
previously used the PEM-only routines).
Fixes key comment regression bz#2306: key pathnames were being lost as
comment fields.
