[SRU][WILY][XENIAL]
[JUSTIFICATION]
Running stress-ng --remap 4 will trip an oops on the remap.
The bug is introduced by the mm/mmap.c changes in patch d15bd6cdbb1c2080fb1fca0035e5af1994f4d14f - AUFS introduced a subtle bug into remap_file_pages; calls to do_mmap_pgoff can lead to a change of the vma->vm_file and so the vma_fput(vma) on the file is incorrect; we should instead fput on the original file.
[FIX]
fput the original file rather than the vma->vm_file. Without the fix, stress-ng --remap 4 will produce an oops in a few seconds, with the fix it is rock solid.
[REGRESSION POTENTIAL]
This only changes the deprecated system call remap_file_pages which is not used much and it is also deprecated, so it should be avoided by user space applications anyhow.
--------------------------------------------------------------------
While faffing around with the deprecated system call remap_file_pages I was able to trigger an OOPs that can be reproduced every time.

[SRU][WILY][XENIAL]
[JUSTIFICATION]
Running stress-ng --remap 4 will trip an oops on the remap.
The bug is introduced by the mm/mmap.c changes in patch d15bd6cdbb1c2080fb1fca0035e5af1994f4d14f - AUFS introduced a subtle bug into remap_file_pages; calls to do_mmap_pgoff can lead to a change of the vma->vm_file and so the vma_fput(vma) on the file is incorrect; we should instead fput on the original file.
[FIX]
fput the original file rather than the vma->vm_file. Without the fix, stress-ng --remap 4 will produce an oops in a few seconds, with the fix it is rock solid.
[REGRESSION POTENTIAL]
This only changes the deprecated system call remap_file_pages which is not used much and it is also deprecated, so it should be avoided by user space applications anyhow.
--------------------------------------------------------------------
While faffing around with the deprecated system call remap_file_pages I was able to trigger an OOPs that can be reproduced every time.

[SRU][WILY][XENIAL]
[JUSTIFICATION]
Running stress-ng --remap 4 will trip an oops on the remap.
The bug is introduced by the mm/mmap.c changes in patch d15bd6cdbb1c2080fb1fca0035e5af1994f4d14f ("UBUNTU: SAUCE: AUFS"). AUFS introduced a subtle bug into remap_file_pages; calls to do_mmap_pgoff can lead to a change of the vma->vm_file and so the vma_fput(vma) on the file is incorrect; we should instead fput on the original file.
[FIX]
fput the original file rather than the vma->vm_file. Without the fix, stress-ng --remap 4 will produce an oops in a few seconds, with the fix it is rock solid.
[REGRESSION POTENTIAL]
This only changes the deprecated system call remap_file_pages which is not used much and it is also deprecated, so it should be avoided by user space applications anyhow.
--------------------------------------------------------------------
While faffing around with the deprecated system call remap_file_pages I was able to trigger an OOPs that can be reproduced every time.
