jobs/ttcn3: io_uring: set memlock to unlimited

io_uring in the kernel memlocks a big amount of space with older
kernels, such as the kernel on host2-deb11build-ansible. It seemed to be
enough to increase it to 1 GiB. However now we see it failing again
with:

  failure during io_uring_queue_init(): Cannot allocate memory
  Aborted (core dumped)

Set it to unlimited to ensure that a low limit is not the reason we see
it failing. If it still happens after this, we probably need to make
sure that we don't run too many SUTs with io_uring in parallel on
jenkins nodes with older kernels.

Osmocom CI and infrastructure files

ansible

Ansible rules for setting up machines of the Osmocom infrastructure. See ansible/README.md.

contrib

Scripts and files that did not fit into other directories.

coverity

Scripts used to submit the osmocom sources for coverity scan. This depends on a tokens.txt, see coverity/get_token.sh.

how to upgrade

  • Download the latest version from here
  • Find the "upgrade considerations" here
  • Place the resulting cov-analysis-linux64-$VERSION.tar.gz in ansible/files
  • Adjust coverity_version in ansible/roles/install-coverity/defaults/main.yml
  • Deploy the ansible playbook:
$ cd ansible
$ ansible-playbook -v -i hosts setup-jenkins-slave.yml -l coverity_slaves -t coverity
  • On success, only one task should be skipped (the "Please download..." task):

jobs

Jenkins Job Builder YAML files defining jenkins jobs. Read jobs/README.adoc for more information about deployment.

lint

The linter running on patches submitted via gerrit. See the wiki page Linting for more information.

qemu-kvm

A script to create a virtual machine with kernel gtp ggsn for qemu-kvm.

scripts

Scripts used by jenkins jobs. Various osmo*/contrib/jenkins.sh scripts assume osmo-ci to be checked out in the build slave user's home, i.e. using a PATH of $HOME/osmo-ci/scripts.

_docker_playground

A clone of docker-playground, so the scripts can build required docker images. This dir gets created on demand by scripts/common.sh, and automatically fetched and reset to "origin/master" (override with $OSMO_BRANCH_DOCKER_PLAYGROUND). The fetch and reset gets skipped if _docker_playground is a symlink. For development, set it up as follows:

$ git clone https://gitea.osmocom.org/osmocom/docker-playground
$ git clone https://gitea.osmocom.org/osmocom/osmo-ci
$ cd osmo-ci
$ ln -s ../docker-playground _docker_playground
