As you note, keeping packets.h and moving things to static inline ends
up creating these backdoor dependencies. I originally removed
packets.[ch] entirely because a file called 'packets.h' and a file
called 'dp-packet.h' feels confusing for developers. The 'packets.h'
file is an overly generic name and felt like going forward it would
create more opportunity for backdoor dependencies. I dissolved it into
a combination of 'dp-packet.h' and 'net-proto.h' for the "on the wire"
network protocol related work. You can see in the initial proposal [0]
going from:
a. Create 'net-proto.h' for network protocol related functions, and
move the 'packets.h' contents there.
b. Move out some additional details to CT and remove unused
function(s).
c. Move the rest into dp-packet.h (because the remaining stuff all
manipulated dp-packet objects based on protocol details) and
delete packets.h
Calling it netaddr.[ch] is fine by me (we're just arguing about a bike
shed there) but it still needs to facilitate separating the linkage. I
think keeping packets.h around doesn't make too much sense, because it
is very generic space, pulls in lots of modules from all over and lends
itself to getting cluttered up with all sorts of vague utilities that
aren't related (eg why are the *_compose in packets.h and not
dp-packet.h, or even dp-protocols.h?). In my split, I moved ALL of the
network protocol details out. That was the important part of the work.
I think it's visible that packets.h became a catchall over the years.
What I mean is, it pulled lots of seemingly unrelated stuff. For
instance, we have flow_*compose, and cfm_*compose in their own headers,
but for some reason, the lacp compose didn't end up in the lacp
header (completely inconsistent) even though those things got moved out.
Once you do the split like you're discussing, you'll see from the
original proposal that packets.[ch] becomes just dp-packet related
functions that insert/remove headers, and so packets.[ch] becomes *less*
descriptive.
After splitting out address related stuff, what's left doesn't make as
much sense together (some leftover consts, structs like ip_header,
tcp_header, etc) sitting alongside the dp-packet helper functions
(push_eth, pop_eth, packet_set_*, etc) with nothing connecting them.
Moving all the *protocol* definitions (structs, address stuff, consts)
to another header+c file, and then folding the remaining dp-packet
related functionality into dp-packet.[ch] seemed to me the cleanest
option. I gave some pushback [1], but it looks like that didn't land
enough and you asked Timothy to change it [2].
Maybe it makes more sense now about the original split proposal?
