@mruffell I've noticed that the users who have tested your kernel got something in common: the remote system mounted as cifs isn't in an Ubuntu server and it's kernel seems to be older than Ubuntu's client one...

Hi everyone, As promised, I uploaded test kernels to the below ppa: https://launchpad.net/~mruffell/+archive/ubuntu/lp2060919-test They are based on 6.5.0-27-generic to keep it simple.

I'm not sure what I'm doing wrong. Maybe you can help. Anyway, I had a look at the stack trace, and it seems to be related to the regression reported here: https://lore.kernel.org/linux- mm/a76b370f93cb928c049b94e1fde0d2da506dfcb2.ca...@amazon.com/T/ But I think its slightly different in the Ubuntu 6.5 kernel. The thread mentions that: commit 7b2404a886f8b91250c31855d287e632123e1746 Author: David Howells Date: Fri Dec 1 00:22:00 2023 + 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 Date: Fri Dec 1 00:22:00 2023 + 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. 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 okay... so 6.1 is different from 6.5. Since we were okay with the patch, we probably didn't need to add anything further. But they fixed 6.1 with: commit 21bb2ba4f1ac1e3a57594be62dd74e7b1401b2b1 Author: Steve French 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 Now, Ubuntu kernels in between upstream stable releases get patches from current upstream stable and long term upstream stable trees. We got both 6.1.x and 6.7.x patches recently... so we pulled in this fix, and it landed in: $ git describe --contains 21bb2ba4f1ac1e3a57594be62dd74e7b1401b2b1 Ubuntu-6.5.0-27.28~162 Wow, what a coincidence. I think this patch is probably not needed in 6.5, and causes the issue. How about I build you a test kernel with "cifs: fix flushing folio regression for 6.1 backport" reverted, and then we see if it fixes things? If it does, I will send a revert to the kernel team. If it doesn't then I will have another look. I'll write back once a test kernel is ready. I'll build you both Jammy HWE and Mantic kernels. If you can help me make a reproducer, that would be great. I can test myself then.

I can mount cifs shares with kernel 6.5.0-27, but when copying files from the share to the same share the process is killed everytime. Same effect using bash "cp" or KDE kio copy via Krusader. Running with kernel 6.5.0-26 anything works perfect.

Same issue on kernel 6.5.0-27-generic #28~22.04.1-Ubuntu -- You received this bug notification because you are a member of Kernel Packages, which is subscribed to linux in Ubuntu. https://bugs.launchpad.net/bugs/2060919 Title: Remote filesystems mounted as CIFS not working after update to Kernel "6.5.0-27-generic #28-Ubuntu" (amd64) or Kernel "6.5.0-1014-raspi #17-Ubuntu" (aarch64). Status in linux package in Ubuntu: Confirmed Status in linux-raspi package in Ubuntu: Confirmed Bug 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.
