Description Germano Massullo 2016-11-08 11:15:20 UTC
In Firefox, I was trying to "Print to file" when I got this


SELinux is preventing 57656220436F6E74656E74 from create access on the file file.

*****  Plugin mozplugger (99.1 confidence) suggests   ************************

If si vuole usare il pacchetto plugin
Then disabilitare i controlli SELinux sui plugin di Firefox.
Do
# setsebool -P unconfined_mozilla_plugin_transition 0

*****  Plugin catchall (1.81 confidence) suggests   **************************

If si crede che 57656220436F6E74656E74 dovrebbe avere possibilità di accesso create sui file file in modo predefinito.
Then si dovrebbe riportare il problema come bug.
E' possibile generare un modulo di politica locale per consentire questo accesso.
Do
allow this access for now by executing:
# ausearch -c '57656220436F6E74656E74' --raw | audit2allow -M my-57656220436F6E74656E74
# semodule -X 300 -i my-57656220436F6E74656E74.pp

Comment 1 Robert Mader 2017-03-17 10:00:04 UTC
I can confirm this on f25:

SELinux is preventing 57656220436F6E74656E74 from create access on the file mozilla.pdf.

*****  Plugin mozplugger (99.1 confidence) suggests   ************************

If you want to use the plugin package
Then you must turn off SELinux controls on the Firefox plugins.
Do
# setsebool -P unconfined_mozilla_plugin_transition 0

*****  Plugin catchall (1.81 confidence) suggests   **************************

If you believe that 57656220436F6E74656E74 should be allowed create access on the mozilla.pdf 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 '57656220436F6E74656E74' --raw | audit2allow -M my-57656220436F6E74656E74
# semodule -X 300 -i my-57656220436F6E74656E74.pp
