Fan Zhang merged [12] and cherry-picked it to stable/2610 and will merge
it once it has been verified.
I merged [14] but it does not need to be cherry-picked to stable/2610
because the hidden visibility gerrit change [15] was merged into master
after stable/2610 branch was pulled.
Thanks,

As mentioned in the ticket, I have a fix [12].
Other contributions related to dpdk/cryptodev do not seem to address
any issue
visible in CSIT, so I will test them later.

I decided to change CSIT code [13] to explicitly set the “natural” layout,
as that does not seem to have any negative effect (26.06 ignores
unknown startup.conf options).

As mentioned in e-mails below, the first issue has been fixed.
As not mentioned yet, two more issues happened since then.
The symbol visibility verification seems to depend on VPP platform,
and octeon was apparently not tested. Here [14] is a minimal fix.
Maintainers of similarly “enabled in verify jobs” plugins/drivers
should check their symbol requirements.
There seem to also be a cabling issue on 3n-oct testbed, not related
to VPP.
I am still working on two more CSIT issues, I will write an e-mail
if they need some support on VPP side, or if they will affect release
results.
Assuming [12] and [14] will get merged to master and cherry-picked to
stable/2610 before RC2,
(and barring my possible future e-mails) I say VPP is ready (enough)
for RC2 from CSIT point of view.

Thanks.
Already merged, and initial testing suggests VPP startup is now stable
in CSIT.

Hi Vratko,

[8] in CSIT.
I have raised following patch to gerrit to fix octeon driver issue
https://gerrit.fd.io/r/c/vpp/+/46835

I plan to discuss those on VPP semimonthly meeting in few minutes,
this is both my agenda and a summary for people not joining that meeting.
RC1 is this week and some issues are quite bad and may warrant some
reverts,
but as bugfixes are allowed until RC2 we have still few weeks time.
1. QAT no traffic after DPDK bump [0].
My bad, I got distracted by transient issues and forgot to re-run
larger test selection.
I am still actively investigating, I have put my findings so far into
a quick ticket [1].
Kai was on CSIT meeting and he mentioned some compile flag for
symmetric ciphers,
but currently plugins/dpdk/cryptodev/ registers zero handlers, which
cannot be correct.
2. Before that, OpenSSL bump [2] had introduced an IPsec HW regression
on 3n-srf.
Both issues are visible in trending [3].
3. New packed/natural buffer layout [4], on Xeon with huge pages it
causes a regression.
I opened a ticket [5] in favor of keeping old behavior (all natural)
as default [6],
but if most of users like the new default I can adapt CSIT to set
“natural”
in startup.conf explicitly instead.
4. Octeon driver got some merges, but now VPP usually [7] does not
start [8] in CSIT.
I am not sure if it is an infra issue or VPP source issue.
I will try to investigate before RC2.
Vratko.
