Any kernel greater than 3.10.0-693* is an internal RH only kernel. They just released 7.5 beta upstream and that has an -830 kernel so the one you're after will appear when 7.5 goes GA in 2 - 4 months time (based on previous releases, no guarantees). |
 |
What method should I be using to complete the following tasks then: Update 7.3 with current software updates (I am holding all of the dozens of systems at 7.3 at present). Fix the systems that I have updated to 7.4 so that I can use HFSC+FQ_Codel without creating random outages for my clients? My product works with HFSC+PFIFO or HFSC+BFIFO but with noticeable performance degradation. |

CentOS cannot release that kernel because we do not have it. Only RH have that kernel and you have to be part of RH to get it or be a customer with a support entitlement so that you can open a paid issue to get access to it. You have the choices of building your own kernel from the latest available kernel source RPM available on vault.centos.org and incorporating the patch(es) that RH applied to it - not easy especially if you don't know what patch it was. Or you can buy a RHEL support entitlement and reproduce the issue on RHEL and raise a support ticket and get the kernel that way or you get to do what the rest of us do and wait for 7.5 to drop and be rebuilt. |

Upstream claims that this was fixed in 3.10.0-693 however the fault is still occurring for me with 3.10.0-862.6.3.el7.x86_64 I did compile my own kernel modules for some older versions which does resolve my issue, but this is very awkward / long winded since I havnt worked out how to compile just the module I need - I end up compiling the entire kernel which is taking some time even with my most powerful machines. |

If you must build your own kernel module, then follow the instructions in this CentOS wiki article: https://wiki.centos.org/HowTos/BuildingKernelModules |

@agoodm Assuming the patch that fixes the issue is this one: https://patchwork.ozlabs.org/patch/803885/ I have built a test centosplus kernel that has the above patch applied: https://people.centos.org/toracat/kernel/7/plus/bug14413/ Can you test to see if this kernel resolves the issue? |

@agoodm A new set of the kernel-plus package is now in: https://people.centos.org/toracat/kernel/7/plus/bug14413v3/ (kernel-plus-3.10.0-862.6.3.bug14413_3.el7) This has the patch from comment 32256 above. |
|
|
Just for info, the referenced patch was discussed in this mailing list thread: https://www.mail-archive.com/netdev@vger.kernel.org/msg240430.html |
|
|
kernel-plus-3.10.0-862.11.6.el7.centos.plus has the patch. |
|
|
This patch (centos-linux-3.10-net_sched_codel-bug14413v3.patch) is no longer needed as of kernel-1127.8.2.el7. |
