Description Horst H. von Brand 2011-07-15 17:11:54 UTC
SELinux is preventing /usr/bin/gdb from 'read' accesses on the file /usr/lib/debug/lib64/libselinux.so.1.debug.

*****  Plugin file (36.8 confidence) suggests  *******************************

If you think this is caused by a badly mislabeled machine.
Then you need to fully relabel.
Do
touch /.autorelabel; reboot

*****  Plugin file (36.8 confidence) suggests  *******************************

If you think this is caused by a badly mislabeled machine.
Then you need to fully relabel.
Do
touch /.autorelabel; reboot

*****  Plugin catchall_labels (23.2 confidence) suggests  ********************

If you want to allow gdb to have read access on the libselinux.so.1.debug file
Then you need to change the label on /usr/lib/debug/lib64/libselinux.so.1.debug
Do
# semanage fcontext -a -t FILE_TYPE '/usr/lib/debug/lib64/libselinux.so.1.debug'
where FILE_TYPE is one of the following: nsplugin_rw_t, system_dbusd_var_lib_t, policykit_auth_exec_t, abrt_t, bin_t, cert_t, tmp_t, usr_t, abrt_var_run_t, noxattrfs, prelink_exec_t, nsplugin_home_t, fusefs_t, locale_t, ld_so_t, nfs_t, proc_t, sysfs_t, sysctl_crypto_t, system_cronjob_var_lib_t, policykit_var_lib_t, abrt_exec_t, rpm_exec_t, abrt_t, lib_t, shell_exec_t, afs_cache_t, abrt_helper_exec_t, modules_object_t, sosreport_tmp_t, abrt_tmp_t, var_lib_t, dbusd_etc_t, ld_so_t, configfile, userdomain, domain, rpm_var_cache_t, abrt_var_cache_t, textrel_shlib_t, abrt_etc_t, fail2ban_var_lib_t, rpm_log_t, var_log_t, policykit_reload_t, mta_exec_type, rpm_script_tmp_t, abrt_var_log_t, rpm_var_lib_t, rpm_var_run_t, net_conf_t, user_cron_spool_t, etc_runtime_t, anon_inodefs_t, sysctl_kernel_t, httpd_modules_t, abrt_var_run_t, ld_so_cache_t, sosreport_exec_t, exec_type, root_t. 
Then execute: 
restorecon -v '/usr/lib/debug/lib64/libselinux.so.1.debug'


*****  Plugin catchall (5.04 confidence) suggests  ***************************

If you believe that gdb should be allowed read access on the libselinux.so.1.debug file by default.
Then you should report this as a bug.
You can generate a local policy module to allow this access.
Do
allow this access for now by executing:
# grep gdb /var/log/audit/audit.log | audit2allow -M mypol
# semodule -i mypol.pp

restorecon -R -v /var/lib/debug


And please yum -y update.
