Peter Hurley 8a8a55105d uml: Fix unsafe pid reference to foreground process group ... Although the tty core maintains a pid reference for the foreground process group, if the foreground process group is changed that pid reference is dropped. Thus, the pid reference used for signalling could become stale. Safely obtain a pid reference to the foreground process group and release the reference after signalling is complete. cc: Jeff Dike <jdike@addtoit.com> Acked-by: Richard Weinberger <richard@nod.at> Signed-off-by: Peter Hurley <peter@hurleysoftware.com> Reviewed-by: Alan Cox <alan@linux.intel.com> Signed-off-by: Greg Kroah-Hartman <gregkh@linuxfoundation.org>		2014-11-05 16:26:13 -08:00
