Minor glitch with Ubuntu 18.04:

$ gcc --version
gcc (Ubuntu 7.3.0-16ubuntu3) 7.3.0

In file included from /usr/include/fcntl.h:290:0,
from ../net/bpfilter/main.c:7:
In function âopenâ,
inlined from âmainâ at ../net/bpfilter/main.c:58:13:
/usr/include/x86_64-linux-gnu/bits/fcntl2.h:50:4: error: call to â__open_missing_modeâ declared with attribute error: open with O_CREAT or O_TMPFILE in second argument needs 3 arguments
__open_missing_mode ();
^~~~~~~~~~~~~~~~~~~~~~
scripts/Makefile.host:107: recipe for target 'net/bpfilter/main.o' failed
make[3]: *** [net/bpfilter/main.o] Error 1

I can't repro on Fedora 27 gcc (GCC) 7.3.1 20180303 (Red Hat 7.3.1-5),
perhaps the GCC is broken on that Ubuntu 18.04 box of mine. The warning/
/error, however, looks potentially legit?
