#19649 fixed VBoy 6.1.10 crash on login with Win7 host, Debian guest gombara Nils
Description

This crash happened on 6.1.8 and 6.1.10, it worked previously on the 6.0 series (last tested 6.0.18 or maybe 20?). Bootup is fine, login screen (ldm) comes up, after entering the username and password the login prompt disappears, and after a while the crash screen shows up. The latest additions are installed. Logs attached. Please let me know what I can do to debug. Thanks!

#19644 fixed Linux kernel version: 5.8 - we need changes (fixed in 6.1.14) Frank Batschulat (Oracle) Frank Batschulat (Oracle)
Description

From: "Larry Finger" <> To: vbox-dev@… Subject: [vbox-dev] Problem with kernel 5.8 Date: Fri, 05 Jun 2020 23:39:08 +0200

In a little over one week, Linus will release Kernel 5.8.0-rc1. Shortly thereafter, openSUSE Tumbleweed will start builds using that kernel. Unless I have patched our copy of the code for the VB kernel modules, my mailbox will be flooded with build failure messages.

Thus far, I have found two incompatibilities with the 5.8 APIs. The first was the removal of get_vm_area(). This one can be trivially replaced with get_vm_area_caller(), which has one additional argument that is always "builtin_return_address(0)."

A second API change is more complicated, and above my understanding. In the associated patch entitled "mm: only allow page table mappings for built-in zsmalloc", symbols map_vm_area() and unmap_kernel_range() are no longer exported. The first of these are used in this snippet found in src/vboxdrv/r0drv/linux/alloc-r0drv-linux.c:

      if (iPage == cPages)
      {
          /*
           * Map the pages.
           *
           * Not entirely sure we really need to set nr_pages and pages  
here, but
           * they provide a very convenient place for storing something we  
need
           * in the free function, if nothing else...
           */
# if LINUX_VERSION_CODE < KERNEL_VERSION(3, 17, 0)
          struct page **papPagesIterator = papPages;
# endif
          pVmArea->nr_pages = cPages;
          pVmArea->pages    = papPages;
          if (!map_vm_area(pVmArea, PAGE_KERNEL_EXEC,
# if LINUX_VERSION_CODE < KERNEL_VERSION(3, 17, 0)
                           &papPagesIterator
# else
                           papPages
# endif
                           ))
          {
              PRTMEMLNXHDREX pHdrEx = (PRTMEMLNXHDREX)pVmArea->addr;
              pHdrEx->pVmArea     = pVmArea;
              pHdrEx->pvDummy     = NULL;
              return &pHdrEx->Hdr;
          }
          /* bail out */
# if LINUX_VERSION_CODE < KERNEL_VERSION(3, 17, 0)
          pVmArea->nr_pages = papPagesIterator - papPages;
# endif
      }

I think the code could use vm_map_ram() to map the papPages array directly, but I would appreciate any help the developers could provide.

Thanks,

Larry

#19636 duplicate VirtualBox 6.1.6 with Hyper-V/Vagrant corrupts downloads oramirez
Description

Setup:

VirtualBox 6.1.6, Vagrant 2.2.9, Windows 10 with Hyper-V enabled.

Steps to reproduce:

  1. vagrant init bento/ubuntu-18.04
  2. vagrant up; vagrant ssh

Inside VM:

  1. wget https://download.docker.com/linux/ubuntu/dists/bionic/pool/stable/amd64/docker-ce_19.03.11~3-0~ubuntu-bionic_amd64.deb (REPEAT 3 TIMES)
  2. sha256sum docker-ce_19.03.11~3-0~ubuntu-bionic_amd64.deb; sha256sum docker-ce_19.03.11~3-0~ubuntu-bionic_amd64.deb.1; sha256sum docker-ce_19.03.11~3-0~ubuntu-bionic_amd64.deb.2

Every time you get a different hash! This does not happen if VM is run directly in Hyper-V, without VirtualBox (vagrant up --provider=hyperv)

Example:
