Error messages with Kernel 5.8.8 #34

Reverting to 5.8.5 makes the issues go away, so I presume this is indeed a kernel change and not sudden file system corruption on my end. Performing a scrub also does not show any issues with my FS: |

Yeah, can confirm for me too. |

That patch in that thread touches code the commit changed so I imagine it fixes compsize, but I haven't checked yet. |

I've tested the patch and indeed it fixes So in principle, this bug can be closed since it's a kernel bug after all, and a fix is available. I personally would leave it open to catch other reporters encountering the same issue so they do not report a duplicate issue, at least until a kernel containing the fix is out, but of course if the |

The patch fixes this for me too, both atop 5.8.8 and 5.9-rc4. Good idea, let's wait until such kernels pass Linus and GregKH. |
|
I'm also affected. Could you please release a new minor version with this fix so that the arch linux package can be updated? https://www.archlinux.org/packages/extra/x86_64/compsize/ |
The fix is a patch for the linux kernel, not compsize |
|
Oh... now I see. The issue was caused by a kernel commit AND fixed by a kernel commit. Sorry, I thought it had to be fixed here. |

When faulting in the pages for the user supplied buffer for the search ioctl, we are passing only the base address of the buffer to the function fault_in_pages_writeable(). This means that after the first iteration of the while loop that searches for leaves, when we have a non-zero offset, stored in 'sk_offset', we try to fault in a wrong page range. So fix this by adding the offset in 'sk_offset' to the base address of the user supplied buffer when calling fault_in_pages_writeable(). Several users have reported that the applications compsize and bees have started to operate incorrectly since commit a48b73e ("btrfs: fix potential deadlock in the search ioctl") was added to stable trees, and these applications make heavy use of the search ioctls. This fixes their issues.

The kernel fix is on the way to mainline and it might catch the 5.8.10 release. |

commit 1c78544eaa4660096aeb6a57ec82b42cdb3bfe5a upstream.
When faulting in the pages for the user supplied buffer for the search
ioctl, we are passing only the base address of the buffer to the function
fault_in_pages_writeable(). This means that after the first iteration of
the while loop that searches for leaves, when we have a non-zero offset,
stored in 'sk_offset', we try to fault in a wrong page range.
So fix this by adding the offset in 'sk_offset' to the base address of the
user supplied buffer when calling fault_in_pages_writeable().
Several users have reported that the applications compsize and bees have
started to operate incorrectly since commit a48b73eca4ceb9 ("btrfs: fix
potential deadlock in the search ioctl") was added to stable trees, and
these applications make heavy use of the search ioctls. This fixes their
issues.

commit 1c78544eaa4660096aeb6a57ec82b42cdb3bfe5a upstream.
When faulting in the pages for the user supplied buffer for the search
ioctl, we are passing only the base address of the buffer to the function
fault_in_pages_writeable(). This means that after the first iteration of
the while loop that searches for leaves, when we have a non-zero offset,
stored in 'sk_offset', we try to fault in a wrong page range.
So fix this by adding the offset in 'sk_offset' to the base address of the
user supplied buffer when calling fault_in_pages_writeable().
Several users have reported that the applications compsize and bees have
started to operate incorrectly since commit a48b73eca4ceb9 ("btrfs: fix
potential deadlock in the search ioctl") was added to stable trees, and
these applications make heavy use of the search ioctls. This fixes their
issues.
