Thanks Ghislain. The existing 4.9.312-vs2.3.9.13 patch worked for me against 4.9.337 with a simple bump of "SUBLEVEL = 337" to the Makefile. I got a clean compile & am about to test on a non critical host. Ghislain, I know you run some regression tests but not sure which & where you got them. Given this is the last 4.9 it would be good if Herbert can generate an official patch & put it on the site. Ideally Herbert is finding time to do the major work, but I have been considering options, if a serious security hole needs urgently patching before then. One option is the Civil Infrastructure "Super Long Term Support" (SLTS) kernels. These are maintained for 32-bit ARM and x86-64 systems in very long-lived infrastructure. ref: https://www.cip-project.org/ They are already supporting 4.4.x to 2026 with a likely extension to 2036, so it should be possible to apply the patch-4.4.302-vs2.3.9.9.diff against their ongoing releases with minimal effort. I'll look into this further next week. For me its going backwards a little, but I already backport the e1000e drivers to 4.9 for current generation hardware & expect it will be fine on 4.4. Ideally a small jump forward would be better. The latter announced SLTS kernels are the 4.19.x & 5.10.x series. A bump of the 4.9.x vserver patches to 4.19.x may be small enough to be done relatively quickly & would get us to 2024 with LTS & at least another decade of SLTS. Perhaps Herbert already has an idea on this. If not I'll run the 4.9 patches against it when I get a chance to get a handle on the scale of conflicts. regards Adrian On Mon, January 9, 2023 17:08, Ghislain Adnet wrote: > hi, > https://www.phoronix.com/news/Linux-4.9.337-LTS-Over > LINUX KERNEL -- > The Linux 4.9 kernel was released back in 2016 and Greg Kroah-Hartman today issued the final point release for that kernel series with the Long Term Support (LTS) period now expired. > After Linux 4.9 was in an upgraded six-year LTS period, Linux 4.9.337 was released this morning as the final update to that kernel series. hope bertl has good news for us ! > -- > cordialement, > Ghislain ADNET. > AQUEOS.
