RHEL Engineering is moving the tracking of its product development work on RHEL 6 through RHEL 9 to Red Hat Jira (issues.redhat.com). If you're a Red Hat customer, please continue to file support cases via the Red Hat customer portal. If you're not, please head to the "RHEL project" in Red Hat Jira and file new tickets here. Individual Bugzilla bugs in the statuses "NEW", "ASSIGNED", and "POST" are being migrated throughout September 2023. Bugs of Red Hat partners with an assigned Engineering Partner Manager (EPM) are migrated in late September as per pre-agreed dates. Bugs against components "kernel", "kernel-rt", and "kpatch" are only migrated if still in "NEW" or "ASSIGNED". If you cannot log in to RH Jira, please consult article #7032570. That failing, please send an e-mail to the RH Jira admins at rh-issues@redhat.com to troubleshoot your issue as a user management inquiry. The email creates a ServiceNow ticket with Red Hat. Individual Bugzilla bugs that are migrated will be moved to status "CLOSED", resolution "MIGRATED", and set with "MigratedToJIRA" in "Keywords". The link to the successor Jira issue will be found under "Links", have a little "two-footprint" icon next to it, and direct you to the "RHEL project" in Red Hat Jira (issue links are of type "https://issues.redhat.com/browse/RHEL-XXXX", where "X" is a digit). This same link will be available in a blue banner at the top of the page informing you that that bug has been migrated.

[root@luther ~]# 

and this is the analysis of the log

[root@luther ~]# ausearch -m AVC -ts 14:45 |audit2allow 


#============= httpd_t ==============
allow httpd_t git_system_content_t:dir { read search open getattr };
allow httpd_t git_system_content_t:file { read getattr open };
allow httpd_t httpd_sys_script_exec_t:file write;
[root@luther ~]# 

Not sure about httpd_sys_script_exec_t (not sure what's the proper label for .egg files), but the rest is probably result of trac accessing (read-only) git files.

Version-Release number of selected component (if applicable):
selinux-policy-3.7.19-131.el6.noarch
Comment 2 Matěj Cepl 2011-12-13 16:06:15 UTC 
OK, with fixing issues with *.egg I am down to the additional module which says

module myTracGit 1.0;

require {
	type httpd_t;
	type git_system_content_t;
	class file { read getattr open };
	class dir { read search open getattr };
}

#============= httpd_t ==============
allow httpd_t git_system_content_t:dir { read search open getattr };
allow httpd_t git_system_content_t:file { read getattr open };

and now Trac seems to work.
Comment 3 Matěj Cepl 2011-12-13 16:06:53 UTC 
I am not sure what I want, whether this module should be included as it is, or whether it should be made into a seboolean.
Comment 4 Daniel Walsh 2011-12-13 19:43:54 UTC 
You probably should use


git_read_generic_system_content_files(httpd_t)
Comment 5 Daniel Walsh 2011-12-13 19:44:51 UTC 
Which we have in F16.
Comment 6 Miroslav Grepl 2011-12-14 11:22:47 UTC 
Yes, I need to backport it.
Comment 9 Karel Srot 2012-05-07 14:36:26 UTC 
Hi Matej, 
could you please test it with recent selinux-policy version?
Thank you in advance.
Comment 10 Matěj Cepl 2012-05-07 19:07:53 UTC 
(In reply to comment #9)
> could you please test it with recent selinux-policy version?

Sorry, I cannot I am afraid. After some more pieces of miserable experience with marketed as lightweight Trac (it's memory consumption is boundless) I went with blamed to be overweight bugzilla which works like charm with much less memory consumed and hugely bigger functionaity. Never underestimate smarts of Perl hackers !. But no, I won't be installing that beast back on my server just to find out that everything works fine (as I expect it to).
