Some usermode helper applications are defined at kernel build time, while others can be changed at runtime. To provide a sane way to filter these, add a new kernel option "STATIC_USERMODEHELPER". This option routes all call_usermodehelper() calls through this binary, no matter what the caller wishes to have called. The new binary (by default set to /sbin/usermode-helper, but can be changed through the STATIC_USERMODEHELPER_PATH option) can properly filter the requested programs to be run by the kernel by looking at the first argument that is passed to it. All other options should then be passed onto the proper program if so desired. To disable all call_usermodehelper() calls by the kernel, set STATIC_USERMODEHELPER_PATH to an empty string. Thanks to Neil Brown for the idea of this feature. Cc: NeilBrown <neilb@suse.com> Signed-off-by: Greg Kroah-Hartman <gregkh@linuxfoundation.org> |
