:SELinux is preventing /root/rpmbuild/BUILD/php-5.4.3/build-fpm/conftest from using the 'ptrace' accesses on a process.
:*****  Plugin catchall_boolean (89.3 confidence) suggests  *******************
:If you want to allow sysadm to debug or ptrace all processes.
:Then you must tell SELinux about this by enabling the 'deny_ptrace' boolean.You can read 'unconfined_selinux' man page for more details.
:setsebool -P deny_ptrace 0
:*****  Plugin catchall (11.6 confidence) suggests  ***************************
:If you believe that conftest should be allowed ptrace access on processes labeled unconfined_t by default.
:Then you should report this as a bug.
:You can generate a local policy module to allow this access.
:allow this access for now by executing:
:# grep conftest /var/log/audit/audit.log | audit2allow -M mypol
:# semodule -i mypol.pp

Comment 1 Miroslav Grepl 2012-05-28 03:42:07 EDT
You can allow it using

# setsebool deny_ptrace 1

or make it default by 

setsebool -P deny_ptrace 0

which we have in new F17 installations by default.
