William Orr added the comment: In the case of EINVAL, OpenBSD returns this if multiple cmsghdrs are attached to a message with sendmsg(2). In this case, those tests should probably be skipped. I've attached the patch that combines haypo's patch with skips referencing this issue wrt. multiple

William Orr added the comment: I'm adding another patch, as adding multiple cmsg's to a single message with sendmsg is a Linux-specific extension. This only enables the problematic patches on Linux. This solves the AIX failures in #20718 as well. -- Added file:
