Re: route export number discrepancy
Hi Ondrej,
thanks for both the fixes - they appear to be working as intended in the lab.
I will come back with definite confirmation to you once we upgrade production
(sometime in March).

Hi
I would be glad if you could try the version from git master branch
(commit 6e8fb66859a17b295cd9246264221a75cdbe6c55). It should fix the
export number issue (at least to the pre-2.0.3/1.6.5 state).

Hi Ondrej, thanks for quick response, and yes I agree that its mostly harmless,
yet it upsets our monitoring, so I need to get to the bottom of it at some
point.

OK, I see that commit, but that would not display preferred counters if
the 'keep filtered' is enabled on a given protocol.
if (c->in_keep_filtered)
cli_msg(-1006, "Routes: %u imported, %u filtered, %u exported",
s->imp_routes, s->filt_routes, s->exp_routes);
else
cli_msg(-1006, "Routes: %u imported, %u exported, %u preferred",
s->imp_routes, s->exp_routes, s->pref_routes);
My preference would be to print out all the 4 counters (including 0 for
filtered
if disabled), and the rationale behind this idea is that this would allow for
at least
some degree of backwards compatibility with scripts that used to parse the
Routes line
in bird 1.6 deployments, which again for reference used to look like this:
Routes: 0 imported, 0 filtered, 0 exported, 0 preferred
So perhaps something among the lines of the below would be acceptable:
diff --git a/nest/proto.c b/nest/proto.c
index ab92d90..a68302d 100644

Let me know what you think.

Hi
This is likely just integer overflow during counter decrease, it is
mostly harmless. We will see how to fix it.

Well, it did not fit into the new design (stats are now per-channel,
while pref counter as defined in 1.6.x was bound to per-protocol stats).
It was also a bit confusing and meant something different than people
expected, so we get repeated questions about it.
But more people wanted it back and it seems that we can redefine it to
both fit to per-channel stats and be less confusing (by counting best
routes in adjacent routing table only), so it is back in the devel
code in git, with slightly different meaning.
