From 13405468f49d4b6e014fdf376f46393f9590769d Mon Sep 17 00:00:00 2001 From: Jakub Kicinski Date: Thu, 24 May 2018 00:41:19 -0700 Subject: bpfilter: don't pass O_CREAT when opening console for debug Passing O_CREAT (00000100) to open means we should also pass file mode as the third parameter. Creating /dev/console as a regular file may not be helpful anyway, so simply drop the flag when opening debug_fd.
