Thanks – again – to Michal Kubeček, who has pointed out that there is still a vulnerability in some VMware (vmmon) code, that is not mitigated by Kernel/Compiler retpoline fixes, as it is written in assembler.. ( See comment on … Continue reading

Thanks to the efforts of mlau on the NVIDIA Devtalk Forum, there is a possible fix for the swiotlb issue with Kernel 4.16.. See https://devtalk.nvidia.com/default/topic/1030082/linux/kernel-4-16-rc1-breaks-latest-drivers-unknown-symbol-swiotlb_map_sg_attrs-/ for details.. For NVIDIA driver 384.111, I had to increment all the nv–linux.h patch line … Continue reading
I had previously tested Kernel 4.14.11-rc1 with the 4.14.9+-patched NVIDIA driver 384.98, and that was OK: ………………….. ld -r -o /home/rgadsdon/kernel/NVIDIA-Linux-x86_64-384.98-41410/kernel/nvidia-modeset/nv-modeset-interface.o /home/rgadsdon/kernel/NVIDIA-Linux-x86_64-384.98-41410/kernel/nvidia-modeset/nvidia-modeset-linux.o Building modules, stage 2.

Just tried the ‘stable-review’ patch for the ‘stable’ Kernel – 4.14.11-rc1, and the same NVIDIA problem is there, and it seems the kernel devs won’t do anything: http://lkml.iu.edu/hypermail/linux/kernel/1712.3/02608.html So – it seems the patch is now a permanent requirement for … Continue reading
Just updated the test system to Kernel 4.14.10, and was ‘somewhat dismayed‘ – to put it politely – that the NVIDIA breakage introduced in 4.14.9 is still there! ………… /home/rgadsdon/kernel/NVIDIA-Linux-x86_64-384.98/kernel/nvidia-uvm/uvm8_va_block.c: In function ‘block_cpu_fault_locked’: /usr/src/linux-4.14.10/arch/x86/include/asm/processor.h:826:39: error: implicit declaration of function ‘task_stack_page’; … Continue reading
More on the Kernel 4.14.9 NVIDIA breakage.. Basically, code that should have only gone into 4.15-rc found its way into 4.14.9 – which is why the existing 4.15 NVIDIA patch fixed it.. Thanks to dinosaur_ on the NVIDIA forum, there … Continue reading
Just updated to VMware Workstation 14.1.0, and release notes are here: https://docs.vmware.com/en/VMware-Workstation-Pro/14.0.0/rn/workstation-141-release-notes.html This now works OK with Kernel 4.14 (tested with 4.14.8) but vmmon is still broken with Kernel 4.15 (tested with 4.15-rc4): ……………. /tmp/modconfig-04hK9s/vmmon-only/linux/hostif.c: In function ‘HostIF_InitUptime’: /tmp/modconfig-04hK9s/vmmon-only/linux/hostif.c:1770:4: error: … Continue reading
Just updated the test system to Kernel 4.15-rc3, and the GPL issue for NVIDIA drivers has been fixed, as mentioned – vaguely – in the brief details here: http://lkml.iu.edu/hypermail/linux/kernel/1712.1/01379.html. NVIDIA driver 384.98, with the first 4.15 patch (see http://rglinuxtech.com/?p=2134 ), … Continue reading
