VMware – Still No Solution for Kernel 6.5..

Adventures With Linux ™ Posted on by

Updated to Kernel 6.5-rc5, and – as expected – vmmon still fails to compile:

CC [M] /tmp/modconfig-s9HCQR/vmmon-only/bootstrap/vmmblob.o
LD [M] /tmp/modconfig-s9HCQR/vmmon-only/vmmon.o
MODPOST /tmp/modconfig-s9HCQR/vmmon-only/Module.symvers
ERROR: modpost: "__pte_offset_map" [/tmp/modconfig-s9HCQR/vmmon-only/vmmon.ko] undefined!

make[1]: *** [Makefile:234: __sub-make] Error 2
make[1]: Leaving directory '/usr/src/linux-6.5-rc5'
make: *** [Makefile:117: vmmon.ko] Error 2

I did find a post relating to this on the kernel dev mailing list, where a request relating to this problem with other code (Android..?) from one of the Linaro devs got a rather smart rebuttal – along the lines of ‘explain why you are doing this’…
As a result, the dev posted a series of patches to fix the problem, but this simply consisted of reverting all the appropriate kernel 6.5-rc changes – which is not a solution!

As I have been testing the 2023 Tech Preview of VMware, I took the liberty of posting the issue in their forum, in the hope of getting some sort of response, as the same error occurs with that pre-release of VMware….

    • Thanks. The vmnet part of the patch seems to be missing some text, but I’ll try the vmmon one – and vmnet with the existing temp patchset seemed to be OK..

  4. Hey, all!

    Glad to have found this thread, as I’m running into the same issue (here in October) with kernel 6.5.

    I took the patch provided (thank you!) and compiled the sources found in /usr/lib/vmware/modules/source/vmmon.tar and vmnet.tar. However, I can’t figure out how to get my kernel to actually load them, or for that matter, VMWare to stop attempting to compile the modules when I open it.

    Any help you all could provide on how to use this patch would be greatly appreciated.

    • So, following David’s comment here, cd into /usr/lib/vmware/modules/source/, untar vmmon.tar and vmnet.tar:

      ~# cd /usr/lib/vmware/modules/source/
      /usr/lib/vmware/modules/source# tar xpf vmmon.tar
      /usr/lib/vmware/modules/source# tar xpf vmnet.tar

      Modify manually vmmon-only/include/pgtbl.h and vmnet-only/bridge.c with the data in the patch, i.e.:

      # vi vmmon-only/include/pgtbl.h, line 94, replace “pte = pte_offset_map(pmd, addr);” with “pte = pte_offset_kernel(pmd, addr);”
      94 pte = pte_offset_kernel(pmd, addr);

      # vi vmnet-only/bridge.c, add this after line 46:
      47 #include

      Delete the tar files (or rename them or move them elsewhere), then retar the two directories:
      /usr/lib/vmware/modules/source# tar cpf vmmon.tar vmmon-only/
      /usr/lib/vmware/modules/source# tar cpf vmnet.tar vmnet-only/

      Start VMWare and you should be good to go.

  6. Sorry, typo:

    “Modify manually vmmon-only/include/pgtbl.h and vmnet-only/bridge.c with the *date* in the patch, i.e.:”

    should read

    “Modify manually vmmon-only/include/pgtbl.h and vmnet-only/bridge.c with the *data* in the patch, i.e.:”
