Hi Daniel, Thanks for the guest access to your sparc 64 system. The problem with stat_driver is intermittent. The attached patch appears to resolve the problem, can you confirm using your view? It looks like the nonce value is never initialized to zero. This intermittently results in garbage b

Yes, a guest account on your sparc system would be helpful. Your observations are curious. I'm interested learning what's happening here. On 07/19/2013 05:16 AM, Daniel Pocock wrote: > and patch ID 2002 <>

With respect to the master branch, you should be able to avoid the patch and compile with -DFORCE_64BIT_ALIGN. The patch provides no value in the master branch. I'll need to address this problem in the openssl-feature branch. There should be no need to force the 64-bit alignment when the cipher

If you don't remove that block from the code after that other var was added… it will cause this error to come back on that branch now that you've forced the 64bit align On Jul 18, 2013, at 5:42 PM, Daniel Pocock wrote: > > > On 18/07/13 21:25, Michael Jerris wrote: >> If that fixed it.. then

If that fixed it.. then the issue is the missing def for FORCE_64BIT_ALIGN. Also of note, that pad shouldn't be there anymore after algorithm was added I suspect, as it always serves the same purpose. On Jul 18, 2013, at 3:10 PM, John Foley wrote: > You're using the legacy crypto implementati

You're using the legacy crypto implementation with that configuration. OpenSSL is not in the picture. Looking at the diffs between master and feature-openssl, there's not much jumping out at me that would have resolved the problem. There are some changes to the Makefile. The only other differen

Which test case was failing? It's possible the test case is no longer included in the feature-openssl branch. I pulled out all the legacy crypto and math from libsrtp in that branch. Have you confirmed the failing test case is still run under the feature-openssl branch? On 07/18/2013 01:42 PM

I should clarify this better. The legacy crypto is still in the branch. It's pulled out depending on how you've configured the library. Can you provide the ./configure options you used to build the library? On 07/18/2013 02:12 PM, John Foley wrote: > Which test case was failing? It's possible
