Hi!
If anyone can tell me the options of "chcon" in seandroid? I'd like to
use "-R" for a recursively modification, but it doesn't work. And the
"--help" doesn't give any options that is available for "chcon".
In addition, can anyone tell me how to make a third-party app
unable to be uninstalled via policy configuration?
Thank you very much!!!
The chcon toolbox command is very minimalist; it doesn't support any
options. Just chcon context path... as the usage message says.
Generally restorecon is preferred; you add the specification to the
file_contexts configuration and then can apply restorecon (which does
support -R).
I don't think there is presently a way to prevent uninstallation of a
third party app. I doubt that maps to any unique set of kernel level
permissions, and the install-time MAC only controls installation of
apps, not uninstallation (beyond the general ability to perform
uninstallation at all - not which apps can be uninstalled).
