Hi all,

Some guys are asking for the original code in private.
Here is our answer:


We are working on reworking the original code, and doing internal legal review.

When it is done,  we will submit the code to FD.io community for IPR review in 
one or two weeks.

Thanks a lot,

Hongjun,

Thank you for the proposal :)  Per the FD.io technical charter, all proposals 
must be out for public review for two weeks prior to approval by the TSC.  I 
believe this makes Nov 8 the earliest TSC meeting where we could approve at the 
TSC.  Would you like to schedule the project creation review for the Nov 8 8am 
PT TSC meeting?  Will you (or other proposers of the project) be able to make 
that time to present the proposal?

You are still leaving me guessing at what you are trying to do.

You can implement these inside of VPP, where you obviously don’t need or use a 
socket API.

Sounds like you are talking about having these protocols implemented on the 
control plane side.
There are many ways of integrating a control plane with VPP.
With e.g. a port mirroring approach, you would use Linux applications 
unchanged. That’s not necessarily where I would go. We have some ideas around 
improvements for the CP/DP interface, and I’m happy to engage in a discussion 
with that, but you would have to share what problem you are trying to solve in 
more detail.

Best regards,
Ole

TAP interface have 2 ends, one is on VPP another one is in linux. that API/CLI 
sets MTU in VPP->linux direction. In opposite direction you need to use linux 
tools to set MTU for linux->VPP direction.
We may consider sending netlink message to kernel asking for different MTU on 
remote side, but i'm not sure if that is right thing to do or not, as MTU in 
theory can bi different on each end

See above... You can manually change MTU on linux side with "ifconfig" or "ip

Re: [**EXTERNAL**] [vpp-dev] TAP v1/v2 API questions

2018-11-07 Thread Coulson, Ken 
Our normal pattern for forwarding plane entities is create/modify/delete, the 
TAP v1 API fit nicely with that.
The desire is to support changing the interface after it's created without 
deleting and re-creating to avoid as much potential traffic disruption as 
possible.
An example is MTU (which neither v1 or v2 support).  The desired maximum MTU 
may not be known at creation time or may change depending on routing so a 
modify capability seems appropriate.
So be specific on your questions, want to control MTU and admin/link 
enable/disable, would like to know link status without polling.

DPDK TAP PMD (and vHost PMD) provide the same APIs as physical devices using 
the rte_eth_dev_*() functions allowing the next layer of code to very similar 
for physical and virtual devices.
DPDK TAP PMD supports MTU, jumbo frames, extended statistics, link status 
change notifications, plus likely other features.  These seem to me to be an 
advantage and not a drawback.
I'm curious about the drawbacks mentioned and advantages of the VPP 
implementation, could you provide a more detail?  More information will 
certainly help!

Per emails on this list tap v1 is being deprecated.
tap v1 create/modify/delete and tap v2 is different in that it only has 
create/delete.

Some questions:
Is the intent to create a tap v2 modify API and/or to add capabilities to set 
interface API?

What exactly would you like to modify? What capabilities?

tap APIs presently have no MTU setting.  Is there any plan to add that 
capability?

Isn't there generic API for that?


Is there any plan to use DPDK tap PMD?

I don't see any benefits and I see several drawbacks of doing that.
Why do you ask?

Re: [vpp-dev] Faulty java version check for JVPP GEN

2018-11-07 Thread Juraj Linkeš 
There's actually a JIRA ticket opened for this, so it seems I'm not the only 
one who's looking for a solution: https://jira.fd.io/browse/VPP-1477

Subject: [vpp-dev] Faulty java version check for JVPP GEN

Hi vpp-devs,

I'm trying to get VPP build (actually make verify for ci purposes) to run on 
Ubuntu1804 and I've hit an issue with java:
checking /usr/lib/jvm/java-11-openjdk-arm64 for Java 8 compiler... found 
version 11
...
/vpp/build-data/../extras/japi/java/jvpp-core/io/fd/vpp/jvpp/core/examples/L2AclExample.java:37:
 error: package javax.xml.bind does not exist
import javax.xml.bind.DatatypeConverter;
 ^
/vpp/build-data/../extras/japi/java/jvpp-core/io/fd/vpp/jvpp/core/examples/L2AclExample.java:123:
 error: cannot find symbol
System.out.println("Mask hex: " + 
DatatypeConverter.printHexBinary(reply.mask));
  ^
  symbol:   variable DatatypeConverter
  location: class L2AclExample

The package in question was deprecated in Java 9 and removed in Java 11, so 
that's the reason for the failure.

Java 8 present on the system and Java 11 gets installed as part of dependency 
installation of make verify (default-jdk-headless), so a workaround along the 
lines of removing Java 11 or reconfiguring Java is not really on the table.

If we want to install default-jdk-headless as part of make install-dep, we 
should be prepared for Java 11 being installed. What's the right way to fix 
this? Use a package other than javax.xml.bind or modify how the build searches 
for Java compilers?

Thanks,
Juraj

[vpp-dev] VPP unit test failures (l2fib, ip4 reassemble) on environments other than x86 Ubuntu 1804

2018-11-07 Thread Juraj Linkeš 
Hi vpp-devs,

There are some failures in unit tests that have cropped up in master on ARM:

*https://jira.fd.io/browse/VPP-1475

*https://jira.fd.io/browse/VPP-1476

I tried Ubuntu1604 and 1804 on ARM and the issues are reproducible on both. 
I've noticed that we switched testing from ubuntu1604 to 1804 on x86 in CI, so 
I've also tried some other OS's on x86 and sure enough, I saw both issues on 
ubuntu1604 and Debian9.

Could someone look into these?

Thanks,
Juraj

Re: [vpp-dev] vppctl issue

2018-11-07 Thread Dave Barach via Lists.Fd.Io 
+1.

If the vpp service is running - and you're using the distributed version of 
/etc/vpp/startup.conf - you'll see this stanza:

api-segment {
  gid vpp
}

Make sure that the user running vppctl is either in the vpp group, or is root.

 Does anyone met below errors when using vppctl and what is the possible
reason?

 

clib_socket_init: connect (fd 3, '/run/vpp/cli.sock'): Connection refused

 

  BTW,  I changed a little vpp code but I suppose it doesn't not related to
this issue and VPP itself is started without any problem

 

My startup configuration:

 

cpu {

main-core 0

corelist-workers 1-3

}

 

unix {

nodaemon

log /tmp/vpp.log

full-coredump

cli-listen /run/vpp/cli.sock

}

 

dpdk {

socket-mem 2048

uio-driver uio_pci_generic

dev :00:06.0 {

num-rx-queues 2

num-tx-queues 2

}

dev :00:09.0

vdev cryptodev_aesni_mb_pmd,socket_id=0

vdev cryptodev_aesni_mb_pmd,socket_id=0

}

 

api-trace {

on

}

 

tap-inject {

enable

}

 

 

BRs,

Kevin

[vpp-dev] vppctl issue

Hello,
 Does anyone met below errors when using vppctl and what is the possible 
reason?

clib_socket_init: connect (fd 3, '/run/vpp/cli.sock'): Connection refused

  BTW,  I changed a little vpp code but I suppose it doesn't not related to 
this issue and VPP itself is started without any problem

My startup configuration:

cpu {
main-core 0
corelist-workers 1-3
}

unix {
nodaemon
log /tmp/vpp.log
full-coredump
cli-listen /run/vpp/cli.sock
}

dpdk {
socket-mem 2048
uio-driver uio_pci_generic
dev :00:06.0 {
num-rx-queues 2
num-tx-queues 2
