:*****  Plugin catchall (100. confidence) suggests  ***************************
:
:If you believe that bash should be allowed write access on the  <Inconnu> 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 VBoxManage /var/log/audit/audit.log | audit2allow -M mypol
:# semodule -i mypol.pp

Comment 2 Miroslav Grepl 2012-02-16 14:43:20 UTC
Could you please execute these steps

$ semanage permissive -a boinc_project_t

Turn on full auditing

$ auditctl -w /etc/shadow -p w

Try to recreate AVC. Then execute

$ ausearch -m avc -ts recent

Hi Miroslav,

Here is the output :

bash-4.2$ sudo semanage permissive -a boinc_project_t
bash-4.2$ sudo auditctl -w /etc/shadow -p w
bash-4.2$ sudo ausearch -m avc -ts recent
<no matches>
bash-4.2$


but I tried another workunit, wich crashed again :-(
