net/sched: Retire tcindex classifier

2023-02-16T08:27:07Z

The tcindex classifier has served us well for about a quarter of a century but has not been getting much TLC due to lack of known users. Most recently it has become easy prey to syzkaller. For this reason, we are retiring it. Signed-off-by: Jamal Hadi Salim Acked-by: Jiri Pirko Signed-off-by: Paolo Abeni

net/sched: Retire dsmark qdisc

2023-02-16T08:27:06Z

The dsmark qdisc has served us well over the years for diffserv but has not been getting much attention due to other more popular approaches to do diffserv services. Most recently it has become a shooting target for syzkaller. For this reason, we are retiring it. Signed-off-by: Jamal Hadi Salim Acked-by: Jiri Pirko Signed-off-by: Paolo Abeni

net/sched: Retire CBQ qdisc

2023-02-16T08:27:06Z

While this amazing qdisc has served us well over the years it has not been getting any tender love and care and has bitrotted over time. It has become mostly a shooting target for syzkaller lately. For this reason, we are retiring it. Goodbye CBQ - we loved you. Signed-off-by: Jamal Hadi Salim Acked-by: Jiri Pirko Signed-off-by: Paolo Abeni

selftests: tc-testing: Add matchJSON to tdc

2022-10-27T03:22:33Z

This allows the use of a matchJSON field in tests to match against JSON output from the command under test, if that command outputs JSON. You specify what you want to match against as a JSON array or object in the test's matchJSON field. You can leave out any fields you don't want to match against that are present in the output and they will be skipped. An example matchJSON value would look like this: "matchJSON": [ { "Value": { "neighIP": { "family": 4, "addr": "AQIDBA==", "width": 32 }, "nsflags": 142, "ncflags": 0, "LLADDR": "ESIzRFVm" } } ] The real output from the command under test might have some extra fields that we don't care about for matching, and since we didn't include them in our matchJSON value, those fields will not be attempted to be matched. If everything we included above has the same values as the real command output, the test will pass. The matchJSON field's type must be the same as the command output's type, otherwise the test will fail. So if the command outputs an array, then the value of matchJSON must also be an array. If matchJSON is an array, it must not contain more elements than the command output's array, otherwise the test will fail.
