[PATCH v5] aio: Add support for the POLLFREE

by Ramji Jiyani

Add support for the POLLFREE flag to force complete iocb inline in aio_poll_wake(). A thread may use it to signal it's exit and/or request to cleanup while pending poll request. In this case, aio_poll_wake() needs to make sure it doesn't keep any reference to the queue entry before returning from wake to avoid possible use after free via poll_cancel() path. UAF issue was found during binder and aio interactions in certain sequence of events [1]. The POLLFREE flag is no more exclusive to the epoll and is being shared with the aio. Remove comment from poll.h to avoid confusion.

[merged] mm-damon-dbgfs-fix-missed-use-of-damon_dbgfs_lock.patch removed from -mm tree

by akpm＠linux-foundation.org

The patch titled Subject: mm/damon/dbgfs: fix missed use of damon_dbgfs_lock has been removed from the -mm tree. Its filename was mm-damon-dbgfs-fix-missed-use-of-damon_dbgfs_lock.patch This patch was dropped because it was merged into mainline or a subsystem tree ------------------------------------------------------ From: SeongJae Park <sj(a)kernel.org> Subject: mm/damon/dbgfs: fix missed use of damon_dbgfs_lock DAMON debugfs is supposed to protect dbgfs_ctxs, dbgfs_nr_ctxs, and dbgfs_dirs using damon_dbgfs_lock. However, some of the code is accessing the variables without the protection. This commit fixes it by protecting all such accesses.

[merged] mm-damon-dbgfs-use-__gfp_nowarn-for-user-specified-size-buffer-allocation.patch removed from -mm tree

by akpm＠linux-foundation.org

The patch titled Subject: mm/damon/dbgfs: use '__GFP_NOWARN' for user-specified size buffer allocation has been removed from the -mm tree. Its filename was mm-damon-dbgfs-use-__gfp_nowarn-for-user-specified-size-buffer-allocation.patch This patch was dropped because it was merged into mainline or a subsystem tree ------------------------------------------------------ From: SeongJae Park <sj(a)kernel.org> Subject: mm/damon/dbgfs: use '__GFP_NOWARN' for user-specified size buffer allocation Patch series "DAMON fixes". This patch (of 2): DAMON users can trigger below warning in '__alloc_pages()' by invoking write() to some DAMON debugfs files with arbitrarily high count argument, because DAMON debugfs interface allocates some buffers based on the user-specified 'count'. if (unlikely(order >= MAX_ORDER)) { WARN_ON_ONCE(!(gfp & __GFP_NOWARN)); return NULL; } Because the DAMON debugfs interface code checks failure of the 'kmalloc()', this commit simply suppresses the warnings by adding '__GFP_NOWARN' flag.

[merged] hugetlb-userfaultfd-fix-reservation-restore-on-userfaultfd-error.patch removed from -mm tree

by akpm＠linux-foundation.org

The patch titled Subject: hugetlb, userfaultfd: fix reservation restore on userfaultfd error has been removed from the -mm tree. Its filename was hugetlb-userfaultfd-fix-reservation-restore-on-userfaultfd-error.patch This patch was dropped because it was merged into mainline or a subsystem tree ------------------------------------------------------ From: Mina Almasry <almasrymina(a)google.com> Subject: hugetlb, userfaultfd: fix reservation restore on userfaultfd error Currently in the is_continue case in hugetlb_mcopy_atomic_pte(), if we bail out using "goto out_release_unlock;" in the cases where idx >= size, or !huge_pte_none(), the code will detect that new_pagecache_page == false, and so call restore_reserve_on_error(). In this case I see restore_reserve_on_error() delete the reservation, and the following call to remove_inode_hugepages() will increment h->resv_hugepages causing a 100% reproducible leak. We should treat the is_continue case similar to adding a page into the pagecache and set new_pagecache_page to true, to indicate that there is no reservation to restore on the error path, and we need not call restore_reserve_on_error(). Rename new_pagecache_page to page_in_pagecache to make that clear.
