Bruno Meneguele 712c39d931 net/bpfilter: fix dprintf usage for /dev/kmsg ... [ Upstream commit 13d0f7b814 ] The bpfilter UMH code was recently changed to log its informative messages to /dev/kmsg, however this interface doesn't support SEEK_CUR yet, used by dprintf(). As result dprintf() returns -EINVAL and doesn't log anything. However there already had some discussions about supporting SEEK_CUR into /dev/kmsg interface in the past it wasn't concluded. Since the only user of that from userspace perspective inside the kernel is the bpfilter UMH (userspace) module it's better to correct it here instead waiting a conclusion on the interface.
