description |
Remote filesystems mounted as CIFS are not working after update to Kernel "6.5.0-27-generic #28-Ubuntu" for x86_64 (and also after updating to Kernel "6.5.0-1014-raspi #17-Ubuntu" in aarch64).
The remote filesystem is correctly mounted and seems to work but trying to write data to the filesystem ends in a kernel error exception. After that error the CIFS filesystem just became unusable.
Previous Kernel version works correctly.
=========================================================
Example for Kernel "6.5.0-27-generic #28-Ubuntu" (x86_64)
=========================================================
# lsb_release -rd
No LSB modules are available.
Description: Ubuntu 23.10
Release: 23.10
# uname -a
Linux fpgmsi 6.5.0-27-generic #28-Ubuntu SMP PREEMPT_DYNAMIC Thu Mar 7 18:21:00 UTC 2024 x86_64 x86_64 x86_64 GNU/Linux
# cat /proc/version_signature
Ubuntu 6.5.0-27.28-generic 6.5.13
----------------------------
How to reproduce the problem
----------------------------
For instance, I'm using KeePassXC (https://launchpad.net/ubuntu/+source/keepassxc) to update a database located at CIFS filesystem. Any change done to that database causes this Kernel error exception:

Copying or modifying a file to the same directory within a cifs mount results in a page fault, and the process that initiated the copy being killed. This could be cp, nautilus, etc.
This results in the following oops:

[Fix]
The stacktrace is very similar to a regression reported to upstream 6.1.y:
https://lore.kernel.org/linux-mm/a76b370f93cb928c049b94e1fde0d2da506dfcb2.camel@amazon.com/T/
The thread mentions that:
commit 7b2404a886f8b91250c31855d287e632123e1746
Author: David Howells <dhowells@redhat.com>
Date: Fri Dec 1 00:22:00 2023 +0000
Subject: cifs: Fix flushing, invalidation and file size with copy_file_range()
Link: https://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git/commit/?id=7b2404a886f8b91250c31855d287e632123e1746
introduced the issue to Debian's 6.1 kernel.
This got backported to Ubuntu in:
commit 3adbe2ccd8b9b8fde93e03958d6176945794d288
Author: David Howells <dhowells@redhat.com>
Date: Fri Dec 1 00:22:00 2023 +0000
Subject: cifs: Fix flushing, invalidation and file size with copy_file_range()
$ git describe --contains 3adbe2ccd8b9b8fde93e03958d6176945794d288
Ubuntu-6.5.0-20.20~107
Which we have been using for some time now, and is not the culprit.
Reading the regression mailing list thread, they mention that things work differently in 6.1:
> Yeah. __filemap_get_folio() works differently in v6.1.y. There it returns a
> folio or NULL. In 6.7 it returns a folio or a negative error code. The error
> check in cifs_flush_folio() needs to change to something like:
>
> folio = filemap_get_folio(inode->i_mapping, index);
> if (!folio)
> return -ENOMEM;
>
> David
6.1.y then got a specific patch to fix the issue in 6.1, which is:
commit 21bb2ba4f1ac1e3a57594be62dd74e7b1401b2b1
Author: Steve French <stfrench@microsoft.com>
Date: Fri Jan 12 23:08:51 2024 -0600
Subject: cifs: fix flushing folio regression for 6.1 backport
Link: https://git.launchpad.net/~ubuntu-kernel/ubuntu/+source/linux/+git/mantic/commit/?id=21bb2ba4f1ac1e3a57594be62dd74e7b1401b2b1
$ git describe --contains 21bb2ba4f1ac1e3a57594be62dd74e7b1401b2b1
Ubuntu-6.5.0-27.28~162
Since the Ubuntu mantic kernel consumes both 6.1.y and 6.7.y / 6.8.y stable patches, this patch was applied to mantic's 6.5 kernel by mistake, and contains the wrong logic for how __filemap_get_folio() works in 6.5.
The fix is to revert "cifs: fix flushing folio regression for 6.1 backport" as a SAUCE patch.
[Testcase]
Start two VMs. One is recommended to be Debian 12, which is what some users have had luck with in the past, as the server, and the client can be mantic.
Server
------
$ sudo apt update
$ sudo apt upgrade
$ sudo apt install samba
$ sudo vim /etc/samba/smb.conf
server min protocol = NT1
[sambashare]
comment = Samba on Ubuntu
path = /home/ubuntu/sambashare
read only = no
browsable = yes
$ mkdir ~/sambashare
$ sudo smbpasswd -a ubuntu
Client
------
$ sudo apt update
$ sudo apt install cifs-utils
$ mkdir ~/share
$ sudo mount -t cifs -o username=ubuntu //192.168.122.185/sambashare ~/share
Password for ubuntu@//192.168.122.185/sambashare:
$ mount -l
...
//192.168.122.185/sambashare on /home/ubuntu/share type cifs (rw,relatime,vers=3.1.1,cache=strict,username=ubuntu,uid=0,noforceuid,gid=0,noforcegid,addr=192.168.122.185,file_mode=0755,dir_mode=0755,soft,nounix,serverino,mapposix,rsize=4194304,wsize=4194304,bsize=1048576,echo_interval=60,actimeo=1,closetimeo=1)
$ ls
hallo.txt hello.txt sample.txt sample2.txt
$ sudo cp hello.txt hello.txt.1
Killed
If you install the test kernel available from the following ppa:
https://launchpad.net/~mruffell/+archive/ubuntu/lp2060919-test
The copy will work as expected.
[Where problems could occur]
Reverting the patch restores logic back to how it was between 6.5.0-20-generic through to 6.5.0-26-generic, which functions, and is well tested by the community.
If a regression were to occur, it would impact all writes to cifs mounts, particularly to the same destination directory as the origin file. There is no known workarounds. |
