[patch] Support for kernel 5.11.1 (Parallels Tools 16.1.3.4960)

This patch worked for me. I had to dust off some old linuxy cobwebs related to patching first. If anyone else is having trouble applying it without DKMS this is what I did:

1. Mount the parallel-tools cd by going to Actions | Install Parallels Tools from the main menu on your MacOS host
2. Copy the whole contents of the cd to your local hard drive (should be same dir where you downloaded the patch), it should be in something like /media/username/Parallels Tools
3. go to the directory where you copied the files from Parallels Tools to
4. go to the kmods directory
5. extract prl_mod.tar.gz with something like tar zxf prl_mod.tar.gz
6. apply the patch as GM originally suggested
   1. cd ..
   2. patch -p1 < parallels-tools-16.1.x.x-kernel-5.11.x.txt. (substitute the right version numbers for your specific patch)
   3. Pick the default response of [n] should you run into any parts of patch that were already applied
7. After the patch has been applied rename prl_mod.tar.gz to something like prl_mod.tar.gz.orig
8. Create a new tarball with the patched files
   1. cd kmods
   2. tar zcf prl_mod.tar.gz *
9. At this point you have patched your local copy of the parallels-tools installer
10. Go to the top level dir of the local installer, cd ..
11. Run the install script, sudo ./install

I hope this makes it a bit easier for the next one to run into this issue.

And add one gripe point from me for the Parallels guys for making us go through this at all on a paid product that supposedly has support.

 

Ok... so that should have been 5.12.13 (vice 5.11.13) but all that is overcome by events because the most recent update is kernel 5.13.4 as of today, so naturally tools won't build against it. This is freaking futile how Parallels' Linux support staff doesn't test kernel betas. Always playing catch-up or DIY.

 

First issue found with 5.13.4 is with how prl_kms_atomic* are no longer compatible pointers with drm:

The patch for 5.13 has been posted a week ago by @Evan123 in reply to your comment . Anyhow, I just created a thread with a patch for 5.13 (my version is a bit cleaner, but essential is the same as Evan's). Additionally, I included a patch for the executable shared folders. I am writing this message from a system running 5.13.4, by the way .

 

Argh... You're right. For some reason I had 5.12.13 on the brain and have been super distracted.

 

@YossiZ I am on Macbook Pro with M1 chip and I managed to install Parallels Tools in Ubuntu Focal ARM64 following your post. Thank you!

 

This happens when a company fails to perform any sort of regression testing before release!

 

patch with 16.1.2 and ubuntu 20.04.3 LTS , prompt "Reserved ..." and select [n] with default option, compile errors at /usr/lib/parallels-tools/kmods/prl_fs/SharedFolders/Guest/Linux/prl_fs/inode.c:780:14 prlfs_getattr, any idea ?

 

By the way, setattr_copy show incompatible pointer type setattr_copu(inode, attr); include/linux/fs.h declare is setattr_copy(struct user_namespace*, struct inode * inode, Type error?

 

Oof, this is embarrassing (or should be) for users to be fixing their software for them.. Thanks for posting these fixes!

 

Well, the 5.17 kernels are out and a new patch is obviously required. I am going to work on it this weekend.

 

I would greatly appreciate a copy of the patch

 

Hi, I just ran into this issue. Is anyone has a patch yet? I plan to purchase after the trial period but this thing is a show stopper for me
