I need more information. Neither the segfault nor the AVC denial occur on my F-11 system. Can you show me the output of "ls -Z /usr/lib/gcl-2.6.8/unixport"? No problem. Michael [michael@localhost ~]$ ls -Z /usr/lib/gcl-2.6.8/unixport -rw-r--r--. root root system_u:object_r:lib_t:s0 init_ansi_gcl.lsp -rw-r--r--. root root system_u:object_r:lib_t:s0 libansi_gcl.a -rw-r--r--. root root system_u:object_r:lib_t:s0 libgclp.a -rwxr-xr-x. root root system_u:object_r:lib_t:s0 saved_ansi_gcl [michael@localhost ~]$ Do you have the gcl-selinux package installed? It should have taken care of giving saved_ansi_gcl the correct SELinux type, which is gcl_exec_t, not lib_t. Does running this:
semodule -l | grep gcl
as a privileged user produce output ("gcl 1.0.1")? If so, does
/sbin/fixfiles -R gcl restore
(again, as a privileged user) change the type of saved_ansi_gcl to gcl_exec_t?
[michael@localhost ~]$ su Password: [root@localhost michael]# semodule -l | grep gcl gcl 1.0.1 [root@localhost michael]# How do I check the type of saved_ansi_gcl? Michael Sorry, I'll provide more detail. First is gcl-selinux installed? The -Z switch to ls shows the type, like what you pasted into comment 2. Try running the fixfiles command from comment 3, then run ls -Z again to see if it had the desired effect. Did you install GCL with SELinux turned off, then later turn SELinux on? (I'm trying to come up with a scenario where the SELinux type gets erased or not set properly in the first place.) I installed with the Administration|Add/Remove Software and it added one extra package that I think was gcl-selinux. Whatever SELinux was for the Fedora 11 installation is what it still is. I made NO changes. Never turned it off. I did load CLISP (months ago) and SBCL (weeks ago) if that makes any difference. [michael@localhost ~]$ su Password: [root@localhost michael]# semodule -l | grep gcl gcl 1.0.1 [root@localhost michael]# man ls Formatting page, please wait... [root@localhost michael]# /sbin/fixfiles -R gcl restore [root@localhost michael]# ls -Z /usr/lib/gcl-2.6.8/unixport -rw-r--r--. root root system_u:object_r:lib_t:s0 init_ansi_gcl.lsp -rw-r--r--. root root system_u:object_r:lib_t:s0 libansi_gcl.a -rw-r--r--. root root system_u:object_r:lib_t:s0 libgclp.a -rwxr-xr-x. root root system_u:object_r:gcl_exec_t:s0 saved_ansi_gcl [root@localhost michael]# This isn't critical for me. I just tried to install to have a look at GCL and SELinux recommended filing with Bugzilla. Michael Well, saved_ansi_gcl has the right type now, so the segfault and AVC denial should be gone. I'll have to try a few installation scenarios to see if I can figure out how it got installed on your machine with an incorrect type. In any case, you should be good to go now. Just remembered: I tried loading Slime (http://common-lisp.net/project/slime/) and McClim (http://common-lisp.net/project/mcclim/) after SBCL, but the install was less than completely successful, though I don't remember any SELinux objections. I have a Fedora 12 Install DVD. Should I hold off installing till you puzzle this out? Michael No, go ahead. If you have the same problem, please post to this bug. I'm planning to install Fedora 12 myself tonight. I'll see if I can reproduce the problem. Looks like the problem followed me to F12. It runs after fixfile in both F11 and F12 (see below). I used a default install and then ran autoten to get Flash and codecs. Then I downloaded GCL with Add/Remove Software.
