>Synopsis: /dev/crypto broken on FreeBSD
>Class: sw-bug
>OS Release: FreeBSD 6.2-RELEASE-p8 i386
>OpenSSL Release: All OpenSSL releases based on
crypto/engine/eng_cryptodev.c v.1.5 and newer (tested on 0.9.8e)
>Description:
The problem check-in #11541
http://cvs.openssl.org/chngview?cn=11541
commited to crypto/engine/eng_cryptodev.c 1.4 -> 1.5
broke the /dev/crypto support on FreeBSD
The current code contain:
--------------
...
if (defined(__unix__) || defined(unix)) && !defined(USG) && \
(defined(OpenBSD) || defined(__FreeBSD_version))
#include <sys/param.h>
...
--------------
Unfortunately, the __FreeBSD_version variable is defined within
sys/param.h
As the #if check the presence of such variable before the sys/param
inclusion, it fail everytime so /dev/crypto support is not compiled in.
>How-To-Repeat:
Run the 'openssl speed' on FreeBSD with and without a
/dev/crypto supported hardware accelerator, compare the results
>Fix:
We can check the existence of variables, but after the sys/param.h
inclusion only.
See the attached patch.
