Upper bits should be zeroed in endianness conversion:- even when there's no need to change endianness (i.e., BPF_FROM_BE on big endian or BPF_FROM_LE on little endian); - after rev16. This patch fixes such bugs by emitting extra instructions to clear upper bits.

The current testsuite catches the 16-bit bugs. I'll send a separate patch that extends test_bpf to catch the 32-bit ones.
looking forward to it. Thanks. -- To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to majord...@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
