Description Juan Orti 2011-12-25 19:38:33 UTC 
Description of problem:
There are +45000 SELinux errors about boinc_client trying to read fifo_file and growing many more each second.

SELinux is preventing /usr/bin/boinc_client from read access on the fifo_file fifo_file.

*****  Plugin catchall (100. confidence) suggests  ***************************

If you believe that boinc_client should be allowed read access on the fifo_file fifo_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 boinc_client /var/log/audit/audit.log | audit2allow -M mypol
# semodule -i mypol.pp


Version-Release number of selected component (if applicable):
selinux-policy-3.10.0-67.fc16.noarch
selinux-policy-targeted-3.10.0-67.fc16.noarch
boinc-client-6.12.35-1.r24014svn.fc16.x86_64

How reproducible:
Just start the service and thousands of errors happen.

Steps to Reproduce:
1. systemctl start boinc-client.service
  
Actual results:

The Boinc service doesn't work and many errors per second happen.

Expected results:

No errors and a functional service.

Additional info:

It was working without problems until today

More verbose output:

SELinux is preventing /usr/bin/boinc_client from 'read' accesses on the fifo_file fifo_file.

*****  Plugin catchall (100. confidence) suggests  ***************************

If cree que de manera predeterminada, boinc_client debería permitir acceso read sobre  fifo_file fifo_file.     
Then debería reportar esto como un error.
Puede generar un módulo de política local para permitir este acceso.
Do
permita el acceso momentáneamente executando:
# grep boinc_client /var/log/audit/audit.log | audit2allow -M mypol
# semodule -i mypol.pp
