Vrouter Enhancements | |||||||||||||||||
| Title | Description | Added by | |||||||||||||||
|---|---|---|---|---|---|---|---|---|---|---|---|---|---|---|---|---|---|
| DPDK: Add bond interface information in vif command | https://contrail-jws.atlassian.net/browse/JCB-219019 | Kiran | |||||||||||||||
| DPDK: Add per core packet statistics (across all vifs) | Kiran | ||||||||||||||||
| vRouter: Expand test case coverage | Kiran | ||||||||||||||||
| DPDK: Display vif flags in vif list (Eg: GRO/GSO) | Kiran | ||||||||||||||||
| Provide debug cli to dump critical data structures | A developer only (initially atleast) debug cli to dump the key internal data structures like rt entry, nh entry, flow entry etc. The CLI should dump all the fields present in the data structure. | Anand | |||||||||||||||
| Add logs in critical vrouter functions | Add logs in critical vrouter functions which can be enabled through some config knob. This may also be exposed via sandesh if required. | Anand | |||||||||||||||
| Conform vRouter to https://patches.dpdk.org/patch/48961/ | DPDK will soon expose a filesystem (FUSE based) where stats will be exposed and resources will be able to be changed. See what can be exposed from the vRouter in that pseudofile system. | Joseph G | |||||||||||||||
| Kernel: add tracepoints | See motivation for uprobes below | Alexander Ankudinov/Valentin Sinitsyn | |||||||||||||||
Agent Enhancements | |||||||||||||||||
| Title | Description | Added by | |||||||||||||||
| A wiki for key introspects commonly used for debugging | Kiran/Anand | ||||||||||||||||
| Logging infra for errors in Agent. dropstats like infra would also be desirable. | Saurabh/Sangarshan | ||||||||||||||||
| A wiki for how vRouter interacts with the Agent ( | Describe Netlink messages used, agent protocol (I believe it's on Github already), what pktX interfaces are for, and how shared memory | )Valentin Sinitsyn (on behalf of Alexander Ankudinov) | is used, in one single location | Alexander Ankudino/Valentin Sinitsyn | |||||||||||||
| More Add `assert()` showing which combinations of flags etc are expected at this pointin the code | This can serve as a type of documentation for which parameter combinations are expected. Say, if FlowStatsCollector expects `VALID` or `EVICTED` flow, it should be asserted | Valentin Sinitsyn (on behalf of Alexander Ankudinov) Alexander Ankudinov/Valentin Sinitsyn | |||||||||||||||
| Record vRouter ↔ Agent interaction (pktX, Netlink etc) so it can be replayed in absence of vRouter | Valentin Alexander Ankudinov/Valentin Sinitsyn | ||||||||||||||||
| Agent: support instrumentation with uprobes | Add some SDT (Statically Defined Tracepoints) to key locations inside the Agent to make instrumentation more straightforward. It's still possible now, but you need to have a good understanding of the source to install probe in the relevant locations | Alexander Ankudinov/Valentin Sinitsyn | |||||||||||||||
