Missing exports : TLSv1_2_client_method, TLSv1_2_server_method #20369

d3x0r · 2018-04-27T18:34:43Z

Version: 10.0.0
Platform: Win32-x64
Subsystem:

TLSv1_2_client_method and TLSv1_2_server_method are not exported.

there is TLS_client_method() and TLS_server_method(); but then node versions previous to 10 don't export that, but instead export the previous methods.

As a workaround - going to investigate a node version definition to #ifdef the code.

addaleax · 2018-04-27T18:37:57Z

Just for clarity: What you are saying is that these symbols are not available to addons on Windows when they should be?

d3x0r · 2018-04-27T18:41:48Z

They previously were available, so addons can link to and use the same version of OpenSSL as node.

Edit: very annoying to workaround; the code that links against most of OpenSSL doesn't itself know about node.h (node_version.h) and it's not an issue with OpenSSL itself; that and I no longer get to control 'only 1.2' instead of 'best available'

Edit2: Node-gyp doesn't seem to have/get the node version to pass to projects; I can get that with cmake-js but was trying to support both (for those that don't have cmake for some odd reason). So I can't even pass it a define when compiling to specify the NODE_MAJOR_VERSION.

Should be easy to fix. @d3x0r Does this patch work for you?

@d3x0r Any luck with that patch?

Applied to version tagged 10.0.0
And ... I dunno; it's not building.

The system cannot find the file specified.

even cleaned everything from old builds so it would build clean... but no joy; I don't know.

if you can get a node 10.0.0 to build; the node.lib should contain

TLSv1_2_server_method TLSv1_2_client_method

should be able to be found in clear text

addaleax · 2018-04-30T11:30:40Z

@d3x0r I’m not sure but that might be caused by 2b85127. Can you revert that locally and try again? I don’t understand why it would fail for you but not in CI, but there’s a decent chance it’s causing that issue

That's after V10.0.0 tag.

I guess it's not that long ago; I can just build against head...

addaleax · 2018-04-30T11:49:08Z

@d3x0r Yes, might even be the case that that fixes the problem for you then. 😄 The patch completely changed the mechanism of the copy operation that’s failing there, so I just thought it would be related to that

d3x0r · 2018-04-30T12:26:01Z

Yes that change restores the two missing methods that I know of :) (clicked wrong button close and commented)

Has appeared again in node 11.0 ( I guess is still an issue on released Node versions?)

sam-github · 2018-11-05T19:11:12Z

I can look into the export defs, but how do I reproduce this? I'm not seeing a difference between 6 and 11, am I using readelf incorrectly?

Ah, sorry, I've no idea how to fix that on Windows. Perhaps @refack does?

Can this be reopened?

Hello @d3x0r,
I'll see what I can do. If I can formulate a way to test this, and we figure out what is causing it, we will do our best to fix it, regardless of if the issue is open or closed.

So the problem is that the TLSv1_2_* were deprecated in openSSL_1_1:
