- RDS self-tests
- ==============
- These scripts provide a coverage test for RDS-TCP by creating two
- network namespaces and running rds packets between them. A loopback
- network is provisioned with optional probability of packet loss or
- corruption. A workload of 50000 hashes, each 64 characters in size,
- are passed over an RDS socket on this test network. A passing test means
- the RDS-TCP stack was able to recover properly. The provided config.sh
- can be used to compile the kernel with the necessary gcov options. The
- kernel may optionally be configured to omit the coverage report as well.
- USAGE:
- run.sh [-d logdir] [-l packet_loss] [-c packet_corruption]
- [-u packet_duplcate]
- OPTIONS:
- -d Log directory. Defaults to tools/testing/selftests/net/rds/rds_logs
- -l Simulates a percentage of packet loss
- -c Simulates a percentage of packet corruption
- -u Simulates a percentage of packet duplication.
- EXAMPLE:
- # Create a suitable gcov enabled .config
- tools/testing/selftests/net/rds/config.sh -g
- # Alternatly create a gcov disabled .config
- tools/testing/selftests/net/rds/config.sh
- # build the kernel
- vng --build --config tools/testing/selftests/net/config
- # launch the tests in a VM
- vng -v --rwdir ./ --run . --user root --cpus 4 -- \
- "export PYTHONPATH=tools/testing/selftests/net/; tools/testing/selftests/net/rds/run.sh"
- An HTML coverage report will be output in tools/testing/selftests/net/rds/rds_logs/coverage/.
