Subject: mm: remove gup_flags FOLL_WRITE games from __get_user_pages()
|
||||||
|
|
||||||
|
This is an ancient bug that was actually attempted to be fixed once
|
||||||
|
(badly) by me eleven years ago in commit 4ceb5db9757a ("Fix
|
||||||
|
get_user_pages() race for write access") but that was then undone due to
|
||||||
|
problems on s390 by commit f33ea7f404e5 ("fix get_user_pages bug").
|
||||||
|
|
||||||
|
In the meantime, the s390 situation has long been fixed, and we can now
|
||||||
|
fix it by checking the pte_dirty() bit properly (and do it better). The
|
||||||
|
s390 dirty bit was implemented in abf09bed3cce ("s390/mm: implement
|
||||||
|
software dirty bits") which made it into v3.9. Earlier kernels will
|
||||||
|
have to look at the page state itself.
|
||||||
|
|
||||||
|
Also, the VM has become more scalable, and what used a purely
|
||||||
|
theoretical race back then has become easier to trigger.
|
||||||
|
|
||||||
|
To fix it, we introduce a new internal FOLL_COW flag to mark the "yes,
|
||||||
|
we already did a COW" rather than play racy games with FOLL_WRITE that
|
||||||
|
is very fundamental, and then use the pte dirty flag to validate that
|
||||||
|
the FOLL_COW flag is still valid.
|
||||||
