Description Joseph 2013-05-17 14:59:00 UTC
When a user submits print job, the job ownership is incorrect.

I have:
drwx--x---  3 root     lp    /var/spool/cups
-rw------- 1 root lp    910 May 17 06:52 c02986
-rw-r----- 1 root lp 391367 May 17 06:51 d02986-001

With this permission, user even being in "lp" group can not delete his own job.
User need to be "root" in order to delete the job.

I don't know with which cups version it did change but in the past I remember user was able to delete his/her own print job.

Which file control print job ownership? 


Reproducible: Always

Comment 1 Robin Johnson archtester Gentoo Infrastructure gentoo-dev Security 2013-05-17 15:55:56 UTC
Not an infra bug.
Comment 2 Joseph 2013-05-17 16:49:34 UTC
I think this bug goes back few years, it was posted on red hat bug forum:
https://bugzilla.redhat.com/show_bug.cgi?id=432029

Additional info:
the permissions within the package as per spec are:
%dir %attr(0755,root,sys) /etc/cups
%dir %attr(1700,root,sys) /var/spool/cups/tmp

Those lines should probably read:

%dir %attr(0775,root,sys) /etc/cups
%dir %attr(1770,root,sys) /var/spool/cups/tmp

as cups-1.1.22rc1/scheduler/conf.c:497
  chmod(ServerRoot, 0775);
and conf.c:551:
    chmod(TempDir, 01770);
Comment 3 Andreas K. Hüttel gentoo-dev 2013-06-26 22:56:09 UTC
Not a regression then.
Comment 4 Joseph 2013-06-27 13:05:25 UTC
So which setting is causing it?

I can delete a print job from the command line without any problem as user:

lpstat -o (lists the current prints jobs)
lprm [print job #]  (removes the print job)
