Is feathercoin ready for the latest Openssl?

ghostlander

Keep with v1.0.1j if in doubt.

ok so 102c is safe? or does it require changes to code?

lizhi

I think so,safe. you don’t need change any code.

http://www.ftc-c.com/pack3/feathercoin-setup.exe

lizhi

delete old code in key.cpp

if (ECDSA_verify(0, (unsigned char*)&hash, sizeof(hash), &vchSig[0], vchSig.size(), pkey) != 1)
        return false;
    return true;

add new code.New versions of OpenSSL will reject non-canonical DER signatures

bool CKey::Verify(uint256 hash, const std::vector& vchSig)
{
                // -1 = error, 0 = bad sig, 1 = good   
		if (vchSig.empty())
		    return false;
		
		// New versions of OpenSSL will reject non-canonical DER signatures. de/re-serialize first.
		unsigned char *norm_der = NULL;
		ECDSA_SIG *norm_sig = ECDSA_SIG_new();
		const unsigned char* sigptr = &vchSig[0];
		assert(norm_sig);
		if (d2i_ECDSA_SIG(&norm_sig, &sigptr, vchSig.size()) == NULL)
		{
		    /* As of OpenSSL 1.0.0p d2i_ECDSA_SIG frees and nulls the pointer on
		     * error. But OpenSSL's own use of this function redundantly frees the
		     * result. As ECDSA_SIG_free(NULL) is a no-op, and in the absence of a
		     * clear contract for the function behaving the same way is more
		     * conservative.
		     */
		    ECDSA_SIG_free(norm_sig);
		    return false;
		}
		int derlen = i2d_ECDSA_SIG(norm_sig, &norm_der);
		ECDSA_SIG_free(norm_sig);
		if (derlen

zerodrama

so delete:

if(ECDSA_verify(…

…

return false

and add:

bool CKey::Verify(…

…

return ret

}

is that right?

lizhi

Yes , I think so. It have added 0.9.5.

yeah but we still a cleanup on isle 5. I imagine everything still points to ‘Bitcoin’ instead of ‘Feathercoin’. The UI updates are nice but as noticed, only the windows exe made it to .9.5, not the master branch. The master branch is still missing the UI changes. There is a lot of cleanup to do with bitcoin branding that was left behind with feathercoin master branch.What work Ive done, Ive lost with recent backup failures. I am in need of GitHub WRITE access. Furthermore we have a FREEDOM issue here that has recently been brought to my attention.

Although Debian and UBUNTU both use SSL, namely OPENSSL, it has one fatal flaw: current implementation is NON-FREE as distributed.

Fedora team have made changes to FREE it, however, these changes remove the code we need to function.(Elliptic curves)

Several Bitcoin-esque projects are affected, as they ALL use openSSL.

The CentOS pactch doesnt seem to make any changes. However, it is noted that there is further work to be done on HARDENING as noted in this patch:

https://github.com/weex/bitcoind-centos/blob/master/makefile.new. Current version with Fedora is 1.0.1k (pull from 22, 21 sources are broken).

Ive noticed severe DATA LOSS occuring on Debian systems with Jessie. UBUNTU introduces bugs that shouldnt be. I cant use either as a result.Looks like Im rebuilding OPENSSL…EDIT: NO GO. EPIC FAIL. I dunno how to proceed now. Bitcoin team uses a static version of openssl included with thier app, so does litecoin. Perhaps we should follow suit.

ALSO:

Packages for Feathercoin for Fedora(and Im sure others) are missing the qt wallet client.This is a HUGE oversight. We need to include both the daemon AND the client.Please repack.

I will tell this to Wellen, but he is at the sea right now.

It’s not a license issue.

It’s a patent issue.

Use it.

And if Certicom does something nasty, start a riot.
