Re: [microblaze-uclinux] Boa + SSL hanging after certificate download



Blast!

I was moving on to profiling openssl, but found that the gprof support in uClibc had been removed not too long ago. I guess that means it didn't work that great?

Any other profiling options that I can use to measure the performance of applications running directly on the board? I may have to settle with desktop profiling and assume the performance bottlenecks are more or less in the same place.

Good news (sort of),

I was able to run openssl encryption methods using the openssl app (RC4-40 worked at least ;).

Bad news: SSH didn't compile on first run, so I'll have to see why that's freaking out on me. (don't have the output at the moment).

Still haven't found out why Boa + SSL is hanging, but openssl might be a good substitute for me.

BTW, the purpose of getting an encryption/decryption algorithm working is to move the fun parts in to hardware, and connect that hardware via FSL links (and use John's driver)!

David,

I didn't know that the speed option implemented fork().  However, I
don't think that would be the reason for Boa hanging.



It's not,  someone asked in it was possible to run "openssl speed",
it will not be possible on a !MMU uClinux system.



I'll give scp a shot.  If I can't get boa working (and SCP does), I
may be able to use that for my project purposes.



Others have it going (so it seems),  so it should be possible ;-)

Cheers,
Davidm

Thanks for the info Ivan!

Are you able to execute the 'openssl speed' command in your
environment?

I do think that it is a problem with the (system/kernel)
configuration on my end, as the guide for openssl and boa+ssl don't
make any mention of hangs or failures.




openssl speed uses fork and has not been ported to uclinux AFAIK.
In fact,  is will be a non-trvial change to make it work on
uClinux :-)
Try the apps,  scp, ssh and use them to determine your performance,

Cheers,
Davidm
