>SELinux is preventing /usr/bin/boinc_client from getattr access on the chr_file /dev/ttyACM0.
>
>*****  Plugin restorecon (90.5 confidence) suggests  *************************
>
>If you want to fix the label. 
>/dev/ttyACM0 default label should be tty_device_t.
>Then you can run restorecon.
>Do
># /sbin/restorecon -v /dev/ttyACM0
>
>*****  Plugin device (9.50 confidence) suggests  *****************************
>
>If you want to allow boinc_client to have getattr access on the ttyACM0 chr_file
>Then you need to change the label on /dev/ttyACM0 to a type of a similar device.
>Do
># semanage fcontext -a -t SIMILAR_TYPE '/dev/ttyACM0'
># restorecon -v '/dev/ttyACM0'
>
>*****  Plugin catchall (1.40 confidence) suggests  ***************************
>
>If you believe that boinc_client should be allowed getattr access on the ttyACM0 chr_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
