Dear all, I got a setroubleshoot popop on the laptop. I am attaching them here: Advice/suggestions/comments greatly appreciated. TIA, Antonio Summary: SELinux is preventing nspluginscan from making the program stack executable. Detailed Description: The nspluginscan application attempted to make its stack executable. This is a potential security problem. This should never ever be necessary. Stack memory is not executable on most OSes these days and this will not change. Executable stack memory is one of the biggest security problems. An execstack error might in fact be most likely raised by malicious code. Applications are sometimes coded incorrectly and request this permission. The SELinux Memory Protection Tests (http://people.redhat.com/drepper/selinux-mem.html) web page explains how to remove this requirement. If nspluginscan does not work and you need it to work, you can configure SELinux temporarily to allow this access until the application is fixed. Please file a bug report (http://bugzilla.redhat.com/bugzilla/enter_bug.cgi) against this package. Allowing Access: Sometimes a library is accidentally marked with the execstack flag, if you find a library with this flag you can clear it with the execstack -c LIBRARY_PATH. Then retry your application. If the app continues to not work, you can turn the flag back on with execstack -s LIBRARY_PATH. Otherwise, if you trust nspluginscan to run correctly, you can change the context of the executable to unconfined_execmem_exec_t. "chcon -t unconfined_execmem_exec_t '/usr/bin/nspluginscan'" You must also change the default file context files on the system in order to preserve them even on a full relabel. "semanage fcontext -a -t unconfined_execmem_exec_t '/usr/bin/nspluginscan'" Fix Command: chcon -t unconfined_execmem_exec_t '/usr/bin/nspluginscan' Additional Information: Source Context unconfined_u:unconfined_r:unconfined_t:SystemLow- SystemHigh Target Context unconfined_u:unconfined_r:unconfined_t:SystemLow- SystemHigh Target Objects None [ process ] Source nspluginscan Source Path /usr/bin/nspluginscan Port <Unknown> Host localhost.localdomain Source RPM Packages kdebase-4.0.3-9.fc9 Target RPM Packages Policy RPM selinux-policy-3.3.1-45.fc10 Selinux Enabled True Policy Type targeted MLS Enabled True Enforcing Mode Enforcing Plugin Name allow_execstack Host Name localhost.localdomain Platform Linux localhost.localdomain 2.6.26-0.17.rc3.fc10.i686 #1 SMP Sun May 18 19:05:03 EDT 2008 i686 i686 Alert Count 11 First Seen Tue 05 Feb 2008 07:13:02 AM CST Last Seen Wed 21 May 2008 08:23:12 AM CDT Local ID 7afb3a36-5b69-486c-a93b-02e714040250 Line Numbers Raw Audit Messages host=localhost.localdomain type=AVC msg=audit(1211376192.783:89): avc: denied { execstack } for pid=3177 comm="nspluginscan" scontext=unconfined_u:unconfined_r:unconfined_t:s0-s0:c0.c1023 tcontext=unconfined_u:unconfined_r:unconfined_t:s0-s0:c0.c1023 tclass=process host=localhost.localdomain type=SYSCALL msg=audit(1211376192.783:89): arch=40000003 syscall=125 success=no exit=-13 a0=bfeee000 a1=1000 a2=1000007 a3=fffff000 items=0 ppid=3166 pid=3177 auid=500 uid=500 gid=500 euid=500 suid=500 fsuid=500 egid=500 sgid=500 fsgid=500 tty=(none) ses=1 comm="nspluginscan" exe="/usr/bin/nspluginscan" subj=unconfined_u:unconfined_r:unconfined_t:s0-s0:c0.c1023 key=(null) Summary: SELinux is preventing nm-system-setti (NetworkManager_t) "read" to ./PolicyKit.reload (system_crond_var_lib_t).

It is also possible that the specific version or configuration of the application is causing it to require additional access. Allowing Access: Sometimes labeling problems can cause SELinux denials. You could try to restore the default system file context for ./PolicyKit.reload, restorecon -v './PolicyKit.reload' If this does not work, there is currently no automatic way to allow this access. Instead, you can generate a local policy module to allow this access - see FAQ (http://fedora.redhat.com/docs/selinux-faq-fc5/#id2961385) Or you can disable SELinux protection altogether.

If you have just added a new disk drive to the system you can relabel it using the restorecon command. Otherwise you should relabel the entire files system.
