Also occurs with Brother MFC 7340. Traceback is identical to the original.
This appears to be caused by SE Linux: SELinux is preventing /usr/local/Brother/cupswrapper/brcupsconfig3 from using the execmem access on a process. ***** Plugin catchall_boolean (89.3 confidence) suggests ****************** If you want to allow cups execmem/execstack Then you must tell SELinux about this by enabling the 'cups_execmem' boolean. You can read 'cupsd_selinux' man page for more details. Do setsebool -P cups_execmem 1 ***** Plugin catchall (11.6 confidence) suggests ************************** If you believe that brcupsconfig3 should be allowed execmem access on processes labeled cupsd_t 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 brcupsconfig3 /var/log/audit/audit.log | audit2allow -M mypol # semodule -i mypol.pp --------- After I executed the setsebool command, printing the test page worked, but another SELinux alert was generated.
