[LU-13783] Support for linux kernel version 5.8

• Status: Resolved
• Project: Lustre
• Fix Version/s: Lustre 2.16.0
• Type: Task
• Priority: Minor
• Reporter: Neil Brown
• Assignee: Neil Brown
• Resolution: Fixed

Description

Now that Linux 5.8 is in the stablization phase it makes sense to support compiling against it.

There are several changes that we need to adjust for.  Some are easy, some require more work.

Linux 5.8:

• removes the fmr_pool API. 
• doesn't use mmap_sem directly any more - use "mmap_read_lock()" and similar
• kernel_setsockopt() has gone - need to use more direct access.
• rdma_reject() needs a new "reason for reject" arg
• NR_UNSTABLE_NFS has gone. Use NR_WRITEBACK instead
• 'dummy_context' in fscrypt has changed to "get_dummy_context", and fscrypt_dummy_context is now fsctype_get_dummy_context
• unexport kallsyms_lookup_name() and kallsyms_on_each_symbol()

 Also:

• __vmalloc() now only has 2 args.
• FIELD_SIZEOF is gone, use sizeof_field
• blkcipher is gone,, use skcipher
• cached rb_tree changes
• sysctl handlers like proc_doinvec now take a kernel pointer rather than a __user pointer

[James A Simmons]

I see what happened. It just wasn't exported in 5.6 but still was there. Now the kernel has the same work around upstream.

I'm have a HWE Ubuntu laptop to work with.

[Jian Yu]

Hi James,
Are you going to try and fix the above issues?

With the latest master branch, I hit the following issues:

• kallsyms_lookup_name() (needs a fix)
• security_release_secctx() (needs a fix)
• kernel_setsockopt() (needs patch https://review.whamcloud.com/43207)
• struct proc_ops (needs to update patch https://review.whamcloud.com/37873)

[James A Simmons]

I like the term help  See I will look at it.

[Jian Yu]

Thank you, James.

[James A Simmons]

I fixed up the struct proc_ops. I'm not seeing the security_release_secctx breakage. I looked at the latest kernel and the protocol is not changed. kallsyms_lookup_name() is going to take me time to figure out. It stopped being exported in 5.6 but now it is an inline function in 5.8. 

[Jian Yu]

Hi James,

I'm not seeing the security_release_secctx breakage. I looked at the latest kernel and the protocol is not changed.

The changes are introduced by linux-hwe-5.8 (5.8.0-22.23~20.04.1). I'm pushing a patch to fix this.

I just found using a wrapper function can resolve the kallsyms_lookup_name() issue. I'm pushing the patch to Gerrit.

Moving the Linux client to 5.8 exposed a few more changes that Ubuntu 20 HWE didn't pick up. One is the change in rdma_reject() and the other is the removal of fscrypt_dummy_context_enabled(). See Linux commit 

ed318a6cc0b620440e65f48eb527dc3df7269ce4 for details.
