[yast-devel] [PATCH 3/3] Add aa-logprof interface
From: Goldwyn Rodrigues <rgoldwyn@xxxxxxxx>

The apparmor_ui_dialog communicates with aa-logprof in JSON.
Each dialog is converted to a yast dialog for input
from the user and returns the actions performed in yast in the
form of JSON response.

An extra opendialog has been used to indicate the end of the logprof
execution.
