Normally, you don't have to do this, as Jan Pechanec's two excellent blogs explain why this is so and talk about OpenSSL in Solaris and the PKCS#11 engine patch that Sun contributed to OpenSSL community. Please read the blogs and you will probably stop here :-).
If, for some reason, you have to build your own OpenSSL from source, and would still like to take advantage of MAU in UltraSPARC T1 on Sun Fire T2000/T1000 to speed up the RSA/DSA operations, I'll show you what I did.
First, download the PKCS#11 engine patch from OpenSSL's Contribution area. There are three PKCS#11 engine patch entries at the bottom of the list -- two for openssl-0.9.7d and one for openssl-0.9.7l. You have to apply the appropriate patch to either OpenSSL 0.9.7d or 0.9.7l, no other versions. For OpenSSL 0.9.7d, use pkcs11_engine-0.9.7d.patch.2006-09-12.gz as the other one suffers from Bug 6411001.
Before starting, there is one subtle thing to note -- the patch command. This PKCS#11 engine patch requires GNU patch and does not work with Solaris patch, so we have to use /usr/bin/gpatch.
Assume you want to patch OpenSSL 0.9.7l. At the directory level same as openssl-0.9.7l directory, unzip the patch:
#gunzip pkcs11_engine-0.9.7l.patch.2006-10-13.gzThen cd into top-level OpenSSL directory and apply the patch
#cd openssl-0.9.7l #gpatch -p 1 < ../pkcs11_engine-0.9.7l.patch.2006-10-13 patching file Configure patching file Makefile.org patching file README.pkcs11 patching file crypto/engine/Makefile patching file crypto/engine/cryptoki.h patching file crypto/engine/eng_all.c patching file crypto/engine/engine.h patching file crypto/engine/hw.ec patching file crypto/engine/hw_pk11.c patching file crypto/engine/hw_pk11_err.c patching file crypto/engine/hw_pk11_err.h patching file crypto/engine/hw_pk11_pub.c patching file crypto/engine/pkcs11.h patching file crypto/engine/pkcs11f.h patching file crypto/engine/pkcs11t.h
(At this point, you can take a look at README.pkcs11. Most of the details are there.)
To build OpenSSL, you need to specify a PKCS#11 library on the system. On Solaris 10 or Solaris Express, it's libpkcs11.so under /usr/lib (32-bit) or /usr/lib/sparcv9 (64-bit). This is how I built 64-bit OpenSSL on a T2000 using Sun Studio cc:
#./Configure solaris64-sparcv9-cc shared --pk11-libname=/usr/lib/sparcv9/libpkcs11.so #makeNote that libcrypto.so and libssl.so will reside in the current directory after the make. To verify whether this self-built OpenSSL really takes advantage of MAU on T2000, do this:
#apps/openssl speed rsa1024 -engine pkcs11 -elapsed -multi 32 [ .. snip .. ] available timing options: TIMES TIMEB HZ=100 [sysconf value] timing function used: sign verify sign/s verify/s rsa 1024 bits 0.000078s 0.000022s 12846.6 45807.1If it's close to 13000 signs/s, MAU is engaged. You can also use
#kstat -n ncp0 | grep rsato compare the RSA counters before and after the speed test.
