Hello again,

Looks like that this patch showed some isses/open points:
- CVE-2021-22897 is white-listed already, but in hardknott is fixed
already
https://github.com/openembedded/openembedded-core/blob/hardknott/meta/recipes-support/curl/curl/CVE-2021-22897.patch
 - So do we have to ignore the patch, or apply and remove the
whitelist, or remove patch from hardknott?
- Https certificate at yocto.io has been expired ;)

Regards,
Andrej

Hardknott is no longer being maintained, so nothing needs to be done there.

Since this is a Windows only bug ("It can only trigger when Schannel
is used, which is the native TLS library in Microsoft Windows") I
think the existing whitelist is fine and we don't need this additional
patch.

Can you give me the url which is giving the expired certificate error?

Thanks!
