[PATCH v2 0/2] iter revert problems

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



For the bug description see 2/2. As mentioned there the current problems
is because of generic_write_checks(), but there was also a similar case
fixed in 5.12, which should have been triggerable by normal
write(2)/read(2) and others.

It may be better to enforce reexpands as a long term solution, but for
now this patchset is quickier and easier to backport.

v2: don't fail it has been justly fully reverted

Pavel Begunkov (2):
  iov_iter: mark truncated iters
  io_uring: don't retry with truncated iter
