Didn't I say that this is a bad idea already in an earlier review?
The only reason why you want it, together with direct_packet_write()
(which I think is another bad idea), is because you use
packet_buf_write() to create a "<header><payload>" in a buf in the
usercode in step 11/12 like this:
+ packet_buf_write(&nbuf, "command=%s\n", filter_type);
+ ret = !direct_packet_write(process->in, nbuf.buf, nbuf.len, 1);
which would be totally unnecessary if you just did strbuf_addf()
into nbuf and used packet_write() like everybody else does.
Puzzled. Why are steps 01/12 and 02/12 an improvement?
