Re: [vpp-dev] CI Job failures: Java Connection Closed Exception

[Dave Wallace]

Folks,

Vanessa performed a Jenkins reset at my request to see if that would 
resolve this problem.  Unfortunately the Jenkins reset did not resolve 
the connection resets. A recheck of gerrit change after the Jenkins 
restart failed with multiple job failures due to TCP connection resets:


https://gerrit.fd.io/r/c/vpp/+/32858/6#message-c77806c2fd58c3c00935e1b5589a402e4b670f9f

There has also been no correlation with Ping Monitor events, Nomad 
cluster events, Nomad host, subnet, or docker image.


Investigation continues in the datapath between the Jenkins openstack 
instance and the Nomad cluster.


Thanks again for your patience.

[vpp-dev] VPP 21.06 - RDMA - Cannot allocate memory

[Sergio Tur]

Hi. We're having some trouble making the native rdma driver work in vpp
21.06 on centos 7.9 installed inside an azure VM with accelerated NICs.
We followed the instructions explained in the vpp wiki but when trying to
create an interface  it returns the error: "Cannot allocate memory".

Has anyone managed to make vpp+rdma (no-dpdk) work in centos 7.9 inside a
VM on azure?

Below is some platform info attached and some of the steps we followed.

--- We upgraded the kernel (just in case), thou it fails with the same
error in the original kernel 3.X that's included by default with centos 7.9

*[root@testvm ~]# uname -r*
*5.13.2-1.el7.elrepo.x86_64*

--- We made sure ulimits memlock is set to unlimited

*[root@testvm ~]# ulimit -a*
*core file size  (blocks, -c) 0*
*data seg size   (kbytes, -d) unlimited*
*scheduling priority (-e) 0*
*file size   (blocks, -f) unlimited*
*pending signals (-i) 63951*
*max locked memory   (kbytes, -l) unlimited*
*max memory size (kbytes, -m) unlimited*
*open files  (-n) 1024*
*pipe size(512 bytes, -p) 8*
*POSIX message queues (bytes, -q) 819200*
*real-time priority  (-r) 0*
*stack size  (kbytes, -s) 8192*
*cpu time   (seconds, -t) unlimited*
*max user processes  (-u) 63951*
*virtual memory  (kbytes, -v) unlimited*
*file locks  (-x) unlimited*

--- We disabled selinux (we want to make it work first)

*[root@testvm ~]# getenforce*
*Disabled*

--- We loaded ib_uverbs

*[root@testvm ~]# modprobe ib_uverbs*
*[root@testvm ~]# lsmod | grep ib_uverbs*
*ib_uverbs 147456  1 mlx5_ib*
*ib_core   356352  2 ib_uverbs,mlx5_ib*

--- We checked the accelerated network cards were actually there and had a
compatible mellanox driver (network 0 is the management interface and it's
not accelerated)

Re: [vpp-dev] vpp main thread crashed at mspace_put

[Satya Murthy]

Thanks Sudhir for the quick inputs.
Will check if we have any leaks.

Also, as a side question, How are you finding leaks in VPP ?
Are you using address sanitizer (or) something else?

Thanks & Regards,
Murthy

Re: [vpp-dev] vpp main thread crashed at mspace_put

[Sudhir CR via lists.fd.io]

Hi Murthy,
We observed this issue when memory is exhausted in our system (due to
memory leak in our application).
After solving the above mentioned issue we have not observed this issue.

Regards,
Sudhir

Simply because there was nobody interested to volunteer to maintain it.

[vpp-dev] Reason for removing SUSE packaging support

[Laszlo Király]

Hello,

Could somebody evolve why the build support for Suse was removed?
Which was the last release with support for build on openSuse?  I found this 
commit only mentioning this removal:

commit bc35f469c89daf0126937580b6972516b5007d3a
Author: Dave Wallace 
Date:   Fri Sep 18 15:35:01 2020 +

build: remove opensuse build infra

- VPP on opensuse has not been supported
  for several releases.

Type: fix

Signed-off-by: Dave Wallace 
Change-Id: I2b5316ad5c20a843b8936f4ceb473f932a5338d9


Is it planned to add it back soon? Or later?

You should be able to change it here:
