Description of problem:
SELinux is preventing /usr/sbin/ifconfig from 'execute' accesses on the file /opt/metasploit/common/lib/libpcre.so.1.0.0.

*****  Plugin restorecon (94.8 confidence) suggests  *************************

If você deseja reparar este rótulo.
/opt/metasploit/common/lib/libpcre.so.1.0.0 rótulo padrão deve ser lib_t.
Then você pode executar o restorecon.
Do
# /sbin/restorecon -v /opt/metasploit/common/lib/libpcre.so.1.0.0

*****  Plugin catchall_labels (5.21 confidence) suggests  ********************

If you want to allow ifconfig to have execute access on the libpcre.so.1.0.0 file
Then você precisará mudar o rótulo em /opt/metasploit/common/lib/libpcre.so.1.0.0
Do
# semanage fcontext -a -t FILE_TYPE '/opt/metasploit/common/lib/libpcre.so.1.0.0'
onde FILE_TYPE é um dos seguintes: abrt_helper_exec_t, ifconfig_exec_t, textrel_shlib_t, brctl_exec_t, insmod_exec_t, ld_so_t, lib_t, prelink_exec_t. 
Então execute: 
restorecon -v '/opt/metasploit/common/lib/libpcre.so.1.0.0'


*****  Plugin catchall (1.44 confidence) suggests  ***************************

If você acredita que o ifconfig deva ser permitido acesso de execute em libpcre.so.1.0.0 file  por default.
Then você precisa reportar este como um erro.
Você pode gerar um módulo de política local para permitir este acesso.
Do
permitir este acesso agora executando:
# grep ifconfig /var/log/audit/audit.log | audit2allow -M mypol
# semodule -i mypol.pp
