sudo modprobe vmblock modprobe: ERROR: could not insert 'vmblock': Unknown symbol in module, or unknown parameter (see dmesg) from journalctl: kernel: vmblock: Unknown symbol readlink_copy (err 0)
I have noticed today the same problem after merging kernel 4.7 and recompiling vmware-modules. readlink_copy() is not anymore exported after commit: https://git.kernel.org/cgit/linux/kernel/git/torvalds/linux.git/commit/?id=bfe8804d908a791b16e3686c101f0d7eca9fb5b9 I don't have experience in that sense, maybe it'd make sense to replace it with generic_readlink() ?
As a quick workaround I replaced: return readlink_copy(buffer, buflen, link) with return generic_readlink(dentry, buffer, buflen) in vmblock_only/linux/inode.c It compiles and now modprobe and I believe it should work. It is duplicating function though. I think we can replace the vfs_readlink and the readlink_copy with a single call to generic_readlink. Take a look and see what you think.
I can verify the cut/paste from and to by window 7 vm is working.
(In reply to Harris Landgarten from comment #3) > I can verify the cut/paste from and to by window 7 vm is working. vmblock should be used to implement the software layer for hard disk emulation, shouldn't be? Anyway generic_readlink() is doing more things than readlink_copy() but I'm not an expert in that area. Before pushing a patch into the overlay I'd like to be sure it's not causing problems. I'm attaching here a proposed patch.

From Vmware Docs: vmblock Module Used in Workstation and Fusion, this module is essential for drag-and-drop copy operations between hosts and guests. I don't think it has anything to do with hard disk emulation. I have tested copy/paste and drag/drop between machines and it is now working.

Ok, good! I'll push later the patch to the overlay
REFERENCE: Bug 616958 : 12.5.7 version bump Current [Overlay] already includes: app-emulation/vmware-modules-308.5.7:0 (Harris Landgarten from comment #6) > I have tested copy/paste and drag/drop between machines and it is now > working. Harris is on "~amd64"; I have tested "amd64" with 12.5.7: CONFIRMATION, WORKSFORME. Current [ebuild] /files contains 308-4.07-01-readlink_copy.patch - "Thanks" to Fabio! To me, this bug seems to be FIXED / OBSOLETE.
