freebsd stable - Jun 2010 - FreeBSD 8.1-PRERELEASE: WARNING ioctl sign-extension ioctl ffffffff8004667e

Hi,

	I am getting more than 4 thousand of the following messages a day:

WARNING pid 24509 (python2.6): ioctl sign-extension ioctl ffffffff8004667e

	I've already recompiled all my python ports and dependencies.
I am running up to date ports (today).

$ uname -a
FreeBSD exxodus.fedaykin.here 8.1-PRERELEASE FreeBSD 8.1-PRERELEASE #10: Thu Jun
17 12:28:13 BRT 2010     lioux@exxodus:/usr/obj/usr/src/sys/LIOUX  amd64

	These messages began this past week but I am not sure what
might be to blame: latest ports or latest -STABLE.

	The specific python port is deluge 1.3 RC1. It was running
fine before this past week of changes.

	Does anyone have an idea what might be causing this? Do I
have to be alarmed by this? The system is reliable despite these
messages.

	Regards,

This ioctl is FIONBIO.
I believe that I saw another report about it on this list recently (~1 week
ago).  But it was for a different software.

I guess it would be some port.

This messages just warns about bad programming, but in this case the ioctl is
processed correctly.

I think we may need to check the code and patch it.  Basically this
means that python (or some .so modules) passed an int or unsigned int as
parameter 'cmd', we need to change it  to unsigned long.

The warning itself should be harmless to my best of knowledge, one can
probably remove the printf in kernel source code as a workaround.

By the way it seems to be a POSIX violation and we didn't seem to really
use so wide cmd, but I have not yet verified everything myself.

Cheers,

  I updated boost-libs with your patch which fixed the  issue. I no longer have
the ioctl warning. :)

  1) I rebuilt the libtorrent-rasterbar-14 then libtorrent-rasterbar-14-python. 

  2) Tried deluge, there were warnings still. 

  3) Then, rebuilt deluge. 

  4) Tried deluge, warnings were gone. 

  I still have the lang/python26 patches you sent earlier. So I have both the
python and boost-libs patches on my system.

  Do you want to me to do any further testing? 

  Regards,

No, that should be good enough.

Thanks for testing my patches!
