Re: [vpp-dev] Linking external libraries to VPP executable
Hi, My plugin is linked to an external lib. When my plugin calls the init function of that external lib, it runs into some problems with symbols (presumably the external lib init function calls a dlopen to load some other files) It seems the problem comes from the fact that VPP calls a dlopen of plugins. A simple executable linking directly to the external library and calling the init function of the external lib does not give the same problem. I prototyped the whole scenario by making a stub executable (acting like VPP executable). Also made a stub shared object (like the plugin) which links to the external lib. Then I did a dlopen of this shared object from my stub executable (just like VPP) where the shared object code calls the init function of external lib. This reproduces the same problem as seen with VPP. I then linked my stub executable with the external library in addition and then everything worked fine. In fact, I went ahead and changed the src/vlib/CMakeLists.txt so that external lib links with vlib. This works fine for me. I just wanted to find out, if there is any generic infra available to link additional external libraries to say, vlib, without fiddling around with the build system of VPP.

[vpp-dev] #vpp #bond How to config bond mode in vpp?
[Edited Message Follows]
we use vpp version 19.08
I config bond in VPP startup.conf
dpdk{
...
vdev eth_bond0,mode=1,slave=:01:00.0,slave=:01:00.1，xmit_policy=l34
..
}
But when vpp start,I show int
DBGvpp# show int
Name Idx State MTU (L3/IP4/IP6/MPLS) Counter
Count
GigabitEthernet1/0/0 1 down 9000/0/0/0
GigabitEthernet1/0/1 2 down 9000/0/0/0
UnknownEthernet2 3 down 9000/0/0/0
local0 0 down 0/0/0/0
when I Set state UnknownEthernet2 up, vpp crash down.
Another question, when I compile VPP, Is need cfg RTE_LIBRTE_PMD_BOND
(build/external/packages/dpdk.mk) option on?
Thanks!

Re: [vpp-dev] Discrepancies between CI jobs and s5ci
This has gone a little off the original topic. Do we want to run the CI tests as an unprivileged user (something as simple as su to a vpp user) or just let the community be aware that the CI test results are different than when run locally? But as to Damjan's and Blaji's comments, I agree. I personally don't like the framework either. From my perspective, it forces *way* too much on the user. My preference is a declarative over programmatic configuration. As an example, I have seen Dave and Andrew both contribute tests where they build an array of commands and fire them off to the cli via the api. To me, that seems like a waste of effort, when vpp provides the ability to exec a script via startup. And you all have put *way* too much effort into complying with the way the test framework decided that you have to modify the startup config. I would rather see you be able to work the way you normally would. in my mind, one should be able to specify a __startup_conf__ = " " string and not have to rely on constructs such as extra_vpp_punt_config and extra_vpp_plugin_config.

[vpp-dev] Linking external libraries to VPP executable
Hello, I am working on VPP 1908. I want to link some external non-vpp libraries to my vpp executable lib. Would it work if I add the path of external lib to vlib/CMakeLists.txt file using 'LINK_LIBRARIES' ? Can anyone tell if this is the right way or if there is any other way ? Any help will be appreciated. Thank you, Siddarth -=-=-=-=-=-=-=-=-=-=-=- Links: You receive all messages sent to this group.

Which application of UDP are you specifically referring to? Cheers, Ole-=-=-=-=-=-=-=-=-=-=-=- Links: You receive all messages sent to this group.

Re: [vpp-dev] IPv6 UDP Datagrams with Zero Checksum- RFC complaint ?
Hi Ole, Thank you for your reply. I am not using any tunneling protocol in my case(IPV6+UDP+ payload) RFC 6935 says, "The update is specified for use by a tunnel protocol that transports packets that are themselves protected by a checksum." >>> In VPP we basically leave it up to the application to decide if it requires the UDP checksum or not. So, will VPP maintain the same behavior even for non-tunneled IPV6 UDP datagrams?

In VPP we basically leave it up to the application to decide if it requires the UDP checksum or not. Best regards, Ole -=-=-=-=-=-=-=-=-=-=-=- Links: You receive all messages sent to this group.
