Description of problem: Tried to log in as a new user for the first time. SELinux is preventing /usr/libexec/gdm-session-worker from 'write' accesses on the directory etc. ***** Plugin catchall_labels (83.8 confidence) suggests ******************** If you want to allow gdm-session-worker to have write access on the etc directory Then you need to change the label on etc Do # semanage fcontext -a -t FILE_TYPE 'etc' where FILE_TYPE is one of the following: admin_home_t, auth_cache_t, auth_home_t, cache_home_t, cgroup_t, config_home_t, data_home_t, dbus_home_t, faillog_t, fonts_cache_t, gconf_home_t, gnome_home_t, gstreamer_home_t, httpd_user_content_t, httpd_user_script_exec_t, icc_data_home_t, init_var_run_t, krb5_host_rcache_t, locale_t, mozilla_plugin_tmpfs_t, pam_var_console_t, pam_var_run_t, root_t, systemd_passwd_var_run_t, telepathy_cache_home_t, telepathy_data_home_t, tmp_t, tmpfs_t, user_fonts_t, user_home_dir_t, user_home_t, user_tmp_t, user_tmpfs_t, var_auth_t, var_lib_t, var_lock_t, var_log_t, var_run_t, var_spool_t, var_t, virt_home_t, xdm_home_t, xdm_log_t, xdm_rw_etc_t, xdm_spool_t, xdm_tmp_t, xdm_tmpfs_t, xdm_var_lib_t, xdm_var_run_t, xkb_var_lib_t, xserver_log_t. Then execute: restorecon -v 'etc' ***** Plugin catchall (17.1 confidence) suggests *************************** If you believe that gdm-session-worker should be allowed write access on the etc directory 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 gdm-session-wor /var/log/audit/audit.log | audit2allow -M mypol # semodule -i mypol.pp Additional Information: Source Context system_u:system_r:xdm_t:s0-s0:c0.c1023 Target Context system_u:object_r:etc_t:s0 Target Objects etc [ dir ] Source gdm-session-wor Source Path /usr/libexec/gdm-session-worker Port <Unknown> Host (removed) Source RPM Packages gdm-3.7.92-2.fc19.x86_64 Target RPM Packages filesystem-3.2-7.fc19.x86_64 Policy RPM selinux-policy-3.12.1-23.fc19.noarch Selinux Enabled True Policy Type targeted Enforcing Mode Permissive Host Name (removed) Platform Linux (removed) 3.9.0-0.rc3.git0.5.fc20.x86_64 #1 SMP Tue Mar 19 01:25:41 UTC 2013 x86_64 x86_64 Alert Count 1 First Seen 2013-03-22 06:54:49 EDT Last Seen 2013-03-22 06:54:49 EDT Local ID ea33782d-c9af-4007-8c4f-7c34d41d3a9d Raw Audit Messages type=AVC msg=audit(1363949689.874:320): avc: denied { write } for pid=2605 comm="gdm-session-wor" name="etc" dev="dm-0" ino=131073 scontext=system_u:system_r:xdm_t:s0-s0:c0.c1023 tcontext=system_u:object_r:etc_t:s0 tclass=dir type=AVC msg=audit(1363949689.874:320): avc: denied { add_name } for pid=2605 comm="gdm-session-wor" name="nshadow" scontext=system_u:system_r:xdm_t:s0-s0:c0.c1023 tcontext=system_u:object_r:etc_t:s0 tclass=dir type=AVC msg=audit(1363949689.874:320): avc: denied { create } for pid=2605 comm="gdm-session-wor" name="nshadow" scontext=system_u:system_r:xdm_t:s0-s0:c0.c1023 tcontext=system_u:object_r:shadow_t:s0 tclass=file type=AVC msg=audit(1363949689.874:320): avc: denied { write } for pid=2605 comm="gdm-session-wor" path="/etc/nshadow" dev="dm-0" ino=163367 scontext=system_u:system_r:xdm_t:s0-s0:c0.c1023 tcontext=system_u:object_r:shadow_t:s0 tclass=file type=SYSCALL msg=audit(1363949689.874:320): arch=x86_64 syscall=open success=yes exit=EFAULT a0=7f92fc72e972 a1=241 a2=1b6 a3=0 items=0 ppid=2522 pid=2605 auid=4294967295 uid=0 gid=0 euid=0 suid=0 fsuid=0 egid=0 sgid=0 fsgid=0 ses=4294967295 tty=(none) comm=gdm-session-wor exe=/usr/libexec/gdm-session-worker subj=system_u:system_r:xdm_t:s0-s0:c0.c1023 key=(null) Hash: gdm-session-wor,xdm_t,etc_t,dir,write audit2allow #============= xdm_t ============== allow xdm_t etc_t:dir { write add_name }; allow xdm_t shadow_t:file { write create }; audit2allow -R require { type xdm_t; } #============= xdm_t ============== auth_manage_shadow(xdm_t) iptables_etc_filetrans_config(xdm_t) Additional info: hashmarkername: setroubleshoot kernel: 3.9.0-0.rc3.git0.5.fc20.x86_64 type: libreport
