sendmsg fails with 'Invalid argument' in OpenBSD

[ghost]

The following special handling of *BSD in authenticate.rb fails on OpenBSD with error 'Invalid argument'. We solved the problem by commenting out the special code and just calling @socket.write as on other systems.

if (RbConfig::CONFIG["target_os"] =~ /bsd/)
    @socket.sendmsg(0.chr, 0, nil, [:SOCKET, :SCM_CREDS, ""])

Thanks for the report. I have tried to reproduce it on 5.1 with MarBSD and there it even fails with undefined method sendmsg' for #Socket:...`
I'll have a closer look.

Ah, sendmsg is only available since ruby-1.9.2.

Sorry, I should have stated my Ruby version, I'm running 1.9.3 on the latest OpenBSD-snapshot (I can't remember the version number now but I can look it up on Monday if needed).
It seems to work without problems using the regular write-call as on the other platforms. I was in the middle of preparing a customer demo so I didn't have time to look deeper into it after I got it working.

Thanks,

Fixed in commit beab496: use SCM_CREDS only on FreeBSD. It's still a hack, I'll consult on thee DBus mailing list for a better solution.
