SELinux is preventing false from read access on the fifo_file fifo_file.
***** Plugin catchall (100. confidence) suggests **************************
If you believe that false 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:
# ausearch -c 'false' --raw | audit2allow -M my-false
# semodule -X 300 -i my-false.pp
