just double checked that the requested revert is part of the
Ubuntu-5.11.0-41.45 proposed kernel.

[Bug 1947709] Re: Drop "UBUNTU: SAUCE: cachefiles: Page leaking in cachefiles_read_backing_file while vmscan is active"

2021-10-19 Thread Andrea Righi 
** Description changed:

  [Impact]
  
  "UBUNTU: SAUCE: cachefiles: Page leaking in cachefiles_read_backing_file
  while vmscan is active" has been applied to fix a page leaking issue.
  
  However a slightly different fix has been applied upstream:
  
  9a24ce5b66f9c8190d63b15f4473600db4935f1f cachefiles: Fix page leak in
  cachefiles_read_backing_file while vmscan is active
  
  Basically we are fixing the same issue in two different ways at the same
  time, but even worse our patch an introduce a potential NULL pointer
  dereference: we do a put_page(newpage) and set newpage = NULL in the
  main for() loop and then we may do additional put_page(newpage) after
  the main for loop if ret == -EEXIST, that would trigger the NULL pointer
  dereference.
  
  [Test case]
  
  No test case or reproducer is available at the moment, this issue has
  been found simply by reviewing the code.
  
  [Fix]
  
  Drop the SAUCE patch and rely on the upstream fix.
  
  [Regression potential]
  
- If the analysis is not correct we may re-introduce a page leak in 
+ If the analysis is not correct we may re-introduce a page leak in
  cachefiles (NFS for example), but it seems unlikely to happen, since the 
upstream fix is addressing the page leaking already.
- I think we should really drop this SAUCE patch from all the kernels that are 
applying the upstream fix already (9a24ce5b66f9c8190d63b15f4473600db4935f1f).
