Re: [vpp-dev] ipsec support for chained buffers.

[Xuekun]

What is the chained buffer used for? For IP fragmentation/reassembly? Because I 
met the issue that seems like IP fragmentation doesn't work on IPSec, while 
work on VxLAN. 
And if yes, when does it plan to be supported?  
Thanks.

Re: [vpp-dev] API changes to trigger email

[Ed Kern via Lists.Fd.Io]

Should be able to…

Not that I have the permissions to do it…

following
https://gerrit-review.googlesource.com/Documentation/user-notify.html#project

My first thought is you would want to end up with something along the lines of

[notify “API”]
email = f...@project1.io
email = f...@project2.io
filter = path:^.*\.api
header = to:
type = submitted_changes


submitted_changes for merges or new_changes  if you wanted to see potential 
changes

My GUESS is that you would need at least a vpp committer to satisfy "To edit 
the project level notify settings, ensure the project owner has Push permission 
already granted for the refs/meta/config branch.”

If it turns out you need something from the LF feel free to open a ticket with 
them or just let me know and ill open it..

Hope this helps,

Ed

P.S.  This should SEND the email…of course additional hoops may need to be 
navigated depending on the receiver..  Non member trying to post type bounces.

At some point in the past we discussed adding a trigger in gerrit to generate 
an email alerting adjacency projects about VPP API changes.
Basically any change in a .api file.

Is that something possible to do?

Re: [vpp-dev] inet raw socket

Option 3.5, if one plans to use any of the transport protocols, would be to

You can create a span ports, with SRC interface is your VirtualEthernet, and

[vpp-dev] Deprecation of old stats framework (stats.api)

[Ole Troan]

Guys,

With the introduction of the new stats framework we want to deprecate the old.
I don’t think there is a clear date for when that will happen yet.
I put in a gerrit to show what the changes would be:
https://gerrit.fd.io/r/#/c/15907/ 

Could those of you depending on src/vpp/stats/stats.api please contact me, 
directly or via the list, so we can work out a plan for getting you onto the 
new framework?

Best regards,
Ole-=-=-=-=-=-=-=-=-=-=-=-

[vpp-dev] MemIf when security is not a concern

[satish . gundu]

Hi ,

I read / hear in the fd.io videos that memif's main motto is to have a secure 
point to point connection between two VPP apps.
If lets say, security is not a concern and I would want to have communication 
between a VPP-dataplane-application and a user-space-control-plane-entity in a 
container world, which is a better choice ? Does Unix domain socket suffices ? 
If I use UDS, then is there any standard piece of code in VPP, which can poll 
all the UDS ?

Appreciate your inputs on this.

Thanks,
Satish

[vpp-dev] MemIf with non-VPP userspace appliation

[satish . gundu]

Hi ,

A novice to  VPP world. 

Trying out VPP memif communication between VPP-dataplane and another process ( 
which is a non-VPP application ).
When we do this, I have to do the IP/UDP processing within the application 
which is kind of duplication of the entire IP/UDP stack ( atleast checksum 
verficiations and fragmentation/ reassembly logic ). This seems to be a big 
overhead in terms of the code maintainance.
Please let me know, if this is a correct way to use Memif mechanism (or) Is it 
designed only for communication between two VPP applications.

Thanks,
Satish

Re: [vpp-dev] how to set cb for keepalive of vapi-connection @ 18.10

[Klement Sekera via Lists.Fd.Io]

Hi,
if you ask vapi to handle keepalives for you, why would you want to get
callbacks for them?

Regards,
Klement
