Looks like you have a labeling problem in /usr. Please # restorecon -R -v /usr Should fix it *** Bug 1297342 has been marked as a duplicate of this bug. *** *** Bug 1297343 has been marked as a duplicate of this bug. *** *** Bug 1297345 has been marked as a duplicate of this bug. *** *** Bug 1297344 has been marked as a duplicate of this bug. *** Did you upgrade?

Description of problem: SELinux is preventing /usr/sbin/cupsd from 'read' accesses on the lnk_file /usr/lib64/libcrypt.so.1. ***** Plugin restorecon (94.8 confidence) suggests ************************ If you want to fix the label. /usr/lib64/libcrypt.so.1 default label should be lib_t. Then you can run restorecon. Do # /sbin/restorecon -v /usr/lib64/libcrypt.so.1 ***** Plugin catchall_labels (5.21 confidence) suggests ******************* If you want to allow cupsd to have read access on the libcrypt.so.1 lnk_file Then you need to change the label on /usr/lib64/libcrypt.so.1 Do # semanage fcontext -a -t FILE_TYPE '/usr/lib64/libcrypt.so.1' where FILE_TYPE is one of the following: admin_home_t, bin_t, boot_t, cert_t, courier_exec_t, cupsd_etc_t, cupsd_exec_t, cupsd_var_lib_t, device_t, devlog_t, etc_runtime_t, etc_t, exim_exec_t, file_context_t, fonts_cache_t, fonts_t, ld_so_t, lib_t, locale_t, man_cache_t, man_t, net_conf_t, postfix_postdrop_t, print_spool_t, proc_t, readable_t, root_t, rpm_script_tmp_t, security_t, selinux_config_t, sendmail_exec_t, shell_exec_t, snmpd_var_lib_t, src_t, sssd_var_lib_t, sysfs_t, system_conf_t, system_db_t, textrel_shlib_t, tmp_t, udev_var_run_t, usbfs_t, usr_t, var_lock_t, var_run_t, var_t. Then execute: restorecon -v '/usr/lib64/libcrypt.so.1' ***** Plugin catchall (1.44 confidence) suggests ************************** If you believe that cupsd should be allowed read access on the libcrypt.so.1 lnk_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 cupsd /var/log/audit/audit.log | audit2allow -M mypol # semodule -i mypol.pp Additional Information: Source Context system_u:system_r:cupsd_t:s0-s0:c0.c1023 Target Context system_u:object_r:unlabeled_t:s0 Target Objects /usr/lib64/libcrypt.so.1 [ lnk_file ] Source cupsd Source Path /usr/sbin/cupsd Port <Unknown> Host (removed) Source RPM Packages cups-2.1.2-1.fc23.x86_64 Target RPM Packages glibc-2.22-7.fc23.x86_64 Policy RPM selinux-policy-3.13.1-158.fc23.noarch Selinux Enabled True Policy Type targeted Enforcing Mode Permissive Host Name (removed) Platform Linux (removed) 4.3.3-300.fc23.x86_64 #1 SMP Tue Jan 5 23:31:01 UTC 2016 x86_64 x86_64 Alert Count 1 First Seen 2016-01-11 09:21:32 CET Last Seen 2016-01-11 09:21:32 CET Local ID d85353d3-bfc3-4b17-b0f9-a640afd129b3 Raw Audit Messages type=AVC msg=audit(1452500492.102:556): avc: denied { read } for pid=2702 comm="cupsd" name="libcrypt.so.1" dev="dm-1" ino=3193829 scontext=system_u:system_r:cupsd_t:s0-s0:c0.c1023 tcontext=system_u:object_r:unlabeled_t:s0 tclass=lnk_file permissive=1 type=SYSCALL msg=audit(1452500492.102:556): arch=x86_64 syscall=open success=yes exit=EINTR a0=7f6f951afe58 a1=80000 a2=7f6f95272148 a3=7f6f95267e48 items=0 ppid=1 pid=2702 auid=4294967295 uid=0 gid=0 euid=0 suid=0 fsuid=0 egid=0 sgid=0 fsgid=0 tty=(none) ses=4294967295 comm=cupsd exe=/usr/sbin/cupsd subj=system_u:system_r:cupsd_t:s0-s0:c0.c1023 key=(null) Hash: cupsd,cupsd_t,unlabeled_t,lnk_file,read Version-Release number of selected component: selinux-policy-3.13.1-158.fc23.noarch Additional info: reporter: libreport-2.6.3 hashmarkername: setroubleshoot kernel: 4.3.3-300.fc23.x86_64 type: libreport
