[merged mm-hotfixes-stable] mm-memory-failure-pass-the-folio-and-the-page-to-collect_procs.patch removed from -mm tree

by Andrew Morton

The quilt patch titled Subject: mm/memory-failure: pass the folio and the page to collect_procs() has been removed from the -mm tree. Its filename was mm-memory-failure-pass-the-folio-and-the-page-to-collect_procs.patch This patch was dropped because it was merged into the mm-hotfixes-stable branch of git://git.kernel.org/pub/scm/linux/kernel/git/akpm/mm ------------------------------------------------------ From: "Matthew Wilcox (Oracle)" <willy(a)infradead.org> Subject: mm/memory-failure: pass the folio and the page to collect_procs() Date: Mon, 18 Dec 2023 13:58:35 +0000 Patch series "Three memory-failure fixes". I've been looking at the memory-failure code and I believe I have found three bugs that need fixing -- one going all the way back to 2010! I'll have more patches later to use folios more extensively but didn't want these bugfixes to get caught up in that. This patch (of 3): Both collect_procs_anon() and collect_procs_file() iterate over the VMA interval trees looking for a single pgoff, so it is wrong to look for the pgoff of the head page as is currently done. However, it is also wrong to look at page->mapping of the precise page as this is invalid for tail pages. Clear up the confusion by passing both the folio and the precise page to collect_procs().

Its filename was selftests-secretmem-floor-the-memory-size-to-the-multiple-of-page_size.patch This patch was dropped because it was merged into the mm-hotfixes-stable branch of git://git.kernel.org/pub/scm/linux/kernel/git/akpm/mm ------------------------------------------------------ From: Muhammad Usama Anjum <usama.anjum(a)collabora.com> Subject: selftests: secretmem: floor the memory size to the multiple of page_size Date: Thu, 14 Dec 2023 15:19:30 +0500 The "locked-in-memory size" limit per process can be non-multiple of page_size. The mmap() fails if we try to allocate locked-in-memory with same size as the allowed limit if it isn't multiple of the page_size because mmap() rounds off the memory size to be allocated to next multiple of page_size. Fix this by flooring the length to be allocated with mmap() to the previous multiple of the page_size. This was getting triggered on KernelCI regularly because of different ulimit settings which wasn't multiple of the page_size.

Its filename was mm-migrate-high-order-folios-in-swap-cache-correctly.patch This patch was dropped because it was merged into the mm-hotfixes-stable branch of git://git.kernel.org/pub/scm/linux/kernel/git/akpm/mm ------------------------------------------------------ From: Charan Teja Kalla <quic_charante(a)quicinc.com> Subject: mm: migrate high-order folios in swap cache correctly Date: Thu, 14 Dec 2023 04:58:41 +0000 Large folios occupy N consecutive entries in the swap cache instead of using multi-index entries like the page cache. However, if a large folio is re-added to the LRU list, it can be migrated. The migration code was not aware of the difference between the swap cache and the page cache and assumed that a single xas_store() would be sufficient. This leaves potentially many stale pointers to the now-migrated folio in the swap cache, which can lead to almost arbitrary data corruption in the future. This can also manifest as infinite loops with the RCU read lock held.

Hence adding the missing read memory barrier to fix this. This is a Load-Load reordering issue, which only occurs on some weak mem-ordering architectures (e.g. ARM64, ALPHA), but not on strong mem-ordering architectures (e.g. X86). And theoretically the problem doesn't only happen on ext4, filesystems that call filemap_read() but don't hold inode lock (e.g. btrfs, f2fs, ubifs ...) will have this problem, while filesystems with inode lock (e.g. xfs, nfs) won't have this problem.
