Description of problem:
SELinux is preventing /usr/libexec/fprintd from 'execute' accesses on the file .

*****  Plugin catchall_labels (83.8 confidence) suggests   *******************

If you want to allow fprintd to have execute access on the  file
Then you need to change the label on $FIX_TARGET_PATH
Do
# semanage fcontext -a -t FILE_TYPE '$FIX_TARGET_PATH'
where FILE_TYPE is one of the following: abrt_helper_exec_t, fprintd_exec_t, ld_so_t, lib_t, policykit_auth_exec_t, prelink_exec_t, textrel_shlib_t. 
Then execute: 
restorecon -v '$FIX_TARGET_PATH'


*****  Plugin catchall (17.1 confidence) suggests   **************************

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

Comment 1 Miroslav Grepl 2014-07-16 07:01:38 UTC
You need to add either labeling for /opt/microchip/mplabcomm1.0/libusb-1.0.so.0.0.0 or just allow it using a local policy to make it working.


# semanage fcontext -a -t lib_t "/opt/microchip/mplabcomm1.0/.*\.so(\.[^/]*)*"
