Package: cups
Version: 1.4.4-1
Severity: important


Some time within the last few weeks, my CUPS server running on Squeeze stopped working with my Lenny CUPS client. The client goes into a loop, chewing up CPU and sending loads of HTTP requests to the server. This is a log excerpt from the server, using the debug log level:

=== Begin ===
D [16/Jul/2010:11:57:53 +0200] cupsdAcceptClient: 10 from 192.168.1.2:631 (IPv4)
D [16/Jul/2010:11:57:53 +0200] cupsdReadClient: 10 OPTIONS * HTTP/1.1
D [16/Jul/2010:11:57:53 +0200] cupsdSetBusyState: Active clients
D [16/Jul/2010:11:57:53 +0200] cupsdAuthorize: No authentication data provided.
D [16/Jul/2010:11:57:53 +0200] cupsdReadClient: 10 Closing because Keep-Alive disabled
D [16/Jul/2010:11:57:53 +0200] cupsdCloseClient: 10
D [16/Jul/2010:11:57:53 +0200] cupsdSetBusyState: Not busy
=== End ===

strace nicely shows the interaction between server and client (with log level set to warning to reduce the clutter, no strace filter options used so this is all that happens):

Without checking the RFC, sending 501 + Connection: close and 200 in direct succession looks terribly broken.
Given the content of the 200 response, it looks like the 501 shouldn't have been sent.

Dear Debian User,

This bug report involves a version of CUPS that is no longer supported
in Debian. Use of our limited, volunteer supported resources is best
served by not keeping around old, hardware-specific and inactive bugs
for longer than desirable, so the report is now being closed. 

You may, of course, wish to review the reported problem. It would be
appreciated if any future investigation could be conducted using the
testing or unstable distributions. If considered necessary, this report
could be re-opened or a new bug report, possibly referencing this one,
submitted. Please note there are now separate cups and cups-filters
packages.

Thank you for your report.

Regards,

Brian.
