Public bug reported: [Impact] With small segment sizes, it is possible for the driver to free an SKB before transmitting it, potentially resulting in a crash.
[Test Case] The test case for this is to use a small MTU (200) and mount an NFS exported directory. Create several (~4) 1M files w/ dd, then copy them locally. However, I have not been able to trigger the crash myself. [Regression Risk] Fix is upstream, so regressions will have upstream support. Fix is limited to a driver that is only applicable to the Cavium Thunder-X SoC, so risk is negligible to other platforms. ** Affects: linux (Ubuntu) Importance: High Assignee: dann frazier (dannf) Status: In Progress ** Affects: linux (Ubuntu Xenial) Importance: High Assignee: dann frazier (dannf) Status: In Progress ** Summary changed: - thunder: + thunder: chip errata w/ multiple CQEs for a TSO packet ** Also affects: linux (Ubuntu Xenial) Importance: Undecided Status: New ** Changed in: linux (Ubuntu Xenial) Status: New => In Progress ** Changed in: linux (Ubuntu Xenial) Importance: Undecided => High ** Changed in: linux (Ubuntu Xenial) Assignee: (unassigned) => dann frazier (dannf) -- You received this bug notification because you are a member of नेपाली भाषा समायोजकहरुको समूह, which is subscribed to Xenial.
