Should I send this request to the developers list rather than here? If so, I'll be happy to do so...
In any case, the short version is: I cross-compiled openssl for target xscale, and could not load the kernel module because some of the symbols (e.g. crypto_register_alg) apparently because they were exported using EXPORT_SYMBOL_GPL, and openssl did not convince the kernel that it could use the _GPL symbols. Or at least that's what it appeared to be. I would have thought that OPENssl, for which I have the source, would have met the requirements to use the _GPL symbols in the kernel. So - the question: Is there some trick I need to do to convince the kernel (2.6.18.8) to allow openssl (0.9.81) kernel module to load? (Without breaking the _GPL symbols) Thanks!

I've compiled openssl to run on an xscale, and it worked fine except for one major issue - I could not load the resulting module until I changed this in crypto/api: EXPORT_SYMBOL_GPL(crypto_register_alg); EXPORT_SYMBOL_GPL(crypto_unregister_alg); EXPORT_SYMBOL_GPL(crypto_alloc_tfm); EXPORT_SYMBOL_GPL(crypto_free_tfm); EXPORT_SYMBOL_GPL(crypto_alg_available); To this: EXPORT_SYMBOL(crypto_register_alg); EXPORT_SYMBOL(crypto_unregister_alg); EXPORT_SYMBOL(crypto_alloc_tfm); EXPORT_SYMBOL(crypto_free_tfm); EXPORT_SYMBOL(crypto_alg_available); The strange thing is that those symbols didn't even show up in the kernel symbol table until I did that - which seems really wrong. I don't want to hack the kernel crypto/api.c file to remove the _GPL stuff, obviously, but why in the world does openssl fail to work - since I have the source to it, I'd think that meets the requirements to be able to use the kernel crypto api - or maybe I missed something? Thanks for any pointers people can give me for how to get openssl to work without changing those lines above. I am using openssl-0.9.8l and kernel 2.6.18.8, targeted to xscale (from x86, using a crosstool - I can get the exact 'model and make' if it matters). Thanks again!
