the following command currently fails:
[root@fedora tc-testing]# ./tdc.py -l
The following test case IDs are not unique:
{'6f5e'}
Please correct them before continuing.
this happens because there are two tests having the same id:
[root@fedora tc-testing]# grep -r 6f5e tc-tests/*
tc-tests/actions/pedit.json: "id": "6f5e",
tc-tests/filters/basic.json: "id": "6f5e",
fix it replacing the latest duplicate id with a brand new one:

[root@fedora tc-testing]# ./tdc.py -i

Concurrent tests use several commands to update rules in parallel: 'find'
prints names of batch files in tmp directory and pipes result to 'xargs'
which runs instance of tc per batch file in parallel. This breaks when used
with ns plugin that adds 'ip netns exec $NS' prefix to the command, which
causes only first command in pipe to be executed in namespace:

A lot of tests reuse $DEV1 veth name for naming dummy device. This causes
problem when tdc is invoked without specifying a test group and tries to
execute all tests. In this case tdc instantiates ns plugin, which creates
veth pair once before running tests. However, if any of the tests that
reuse $DEV1 run before test that depend on ns plugin, it will delete $DEV1
as a part of teardown section:

This patch restores the original behaviour for tdc prior to the
introduction of the plugin system, where the network namespace
functionality was split from the main script.
It introduces the concept of required plugins for testcases,
and will automatically load any plugin that isn't already
enabled when said plugin is required by even one testcase.
Additionally, the -n option for the nsPlugin is deprecated
so the default action is to make use of the namespaces.
Instead, we introduce -N to not use them, but still create
the veth pair.
buildebpfPlugin's -B option is also deprecated.
If a test cases requires the features of a specific plugin
in order to pass, it should instead include a new key/value
pair describing plugin interactions:
"plugins": {
"requires": "buildebpfPlugin"
},
A test case can have more than one required plugin: a list
can be inserted as the value for 'requires'.

Implementation of function rhashtable_insert_fast() check if its internal
helper function __rhashtable_insert_fast() returns non-NULL pointer and
seemingly return -EEXIST in such case. However, since
__rhashtable_insert_fast() is called with NULL key pointer, it never
actually checks for duplicates, which means that -EEXIST is never returned
to the user. Use rhashtable_lookup_insert_fast() hash table API instead. In
order to verify that it works as expected and prevent the problem from
happening in future, extend tc-tests with new test that verifies that no
new filters with existing key can be inserted to flower classifier.

the following script:
# tc qdisc add dev crash0 clsact
# tc filter add dev crash0 egress matchall \
> action simple sdata hello pass index 90
# tc actions replace action simple \
> sdata world goto chain 42 index 90 cookie c1a0c1a0
# tc action show action simple
had the following output:
Error: Failed to init TC action chain.
We have an error talking to the kernel
total acts 1
action order 0: Simple <world>
index 90 ref 2 bind 1
cookie c1a0c1a0
Then, the first packet transmitted by crash0 made the kernel crash:
