| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | When we apply a filter that will only leave child trace events, we receive a ZeroDivisionError when calculating the percentages.

This is not common practice for a sort key function so let's replace it. Additionally, the function 'sorted' has already a parameter for reversing the result therefore the inversion of the values is unneeded. The check for stats[x][1] is also superfluous as it's ensured that this value is initialized with 0.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | For tests using veth interfaces, the test infrastructure can create the netdevs if they do not exist.

The main changes are: 1) Extend bpftool to build up CFG information of eBPF programs and add an option to dump this in DOT format such that this can later be used with DOT graphic tools (xdot, graphviz, etc) to visualize it. Part of the analysis performed is sub-program detection and basic-block partitioning, from Jiong. 2) Multiple enhancements for bpftool's batch mode, more specifically the parser now understands comments (#), continuation lines (\), and arguments enclosed between quotes. Also, allow to read from stdin via '-' as input file, all from Quentin. 3) Improve BPF kselftests by i) unifying the rlimit handling into a helper that is then used by all tests, and ii) add support for testing tail calls to test_verifier plus add tests covering all corner cases. The latter is especially useful for testing JITs, from Daniel. 4) Remove x64 JIT's bpf_flush_icache() since flush_icache_range() is a noop on x64, from Daniel. 5) Fix one more occasion in BPF samples where we do not detach the BPF program from the cgroup after completion, from Prashant. ==================== Signed-off-by: David S.

Linux Traffic Control (tc) unit testing suite's code quality improved is improved with this patch. According to python documentation; "The built-in string class provides the ability to do complex variable substitutions and value formatting via the format() method described in PEP 3101. " but the project was using old type formattings and new type string formattings together, this patch's main purpose is converting all old types to new types.
