I have one question regarding the FIPS patch in
http://pkgs.fedoraproject.org/cgit/openssh.git/tree/openssh-6.7p1-fips.patch
:
I assume somewhere from within the OpenSSH code it should invoke
FIPS_set_mode API, but all I saw was FIPS_mode().
Does FIPS_mode() serve the same purposes as FIPS_set_mode()?
FIPS_mode() is openssl function [1]. As manual page says, it determines
if the FIPS mode is enabled. The other function FIPS_mode_set() [2] is
used to modify FIPS status (enables/disables).
Openssh itself should not change the FIPS mode. It should behave
according to the system setup (FIPS mode should be set up system-wide).
Also the patch is for OpenSSH 7.0. Is there a patch for OpenSSH 6.6?
You should be able to go back in the git history to 6.6 version or put
hands on CentOS patches [3], where we use 6.6 version.
