[patch 07/14] mm, page_alloc: fix build_zonerefs_node()

by Andrew Morton

From: Juergen Gross <jgross(a)suse.com> Subject: mm, page_alloc: fix build_zonerefs_node() Since commit 6aa303defb74 ("mm, vmscan: only allocate and reclaim from zones with pages managed by the buddy allocator") only zones with free memory are included in a built zonelist. This is problematic when e.g. all memory of a zone has been ballooned out when zonelists are being rebuilt. The decision whether to rebuild the zonelists when onlining new memory is done based on populated_zone() returning 0 for the zone the memory will be added to. The new zone is added to the zonelists only, if it has free memory pages (managed_zone() returns a non-zero value) after the memory has been onlined. This implies, that onlining memory will always free the added pages to the allocator immediately, but this is not true in all cases: when e.g. running as a Xen guest the onlined new memory will be added only to the ballooned memory list, it will be freed only when the guest is being ballooned up afterwards. Another problem with using managed_zone() for the decision whether a zone is being added to the zonelists is, that a zone with all memory used will in fact be removed from all zonelists in case the zonelists happen to be rebuilt. Use populated_zone() when building a zonelist as it has been done before that commit. There was a report that QubesOS (based on Xen) is hitting this problem. Xen has switched to use the zone device functionality in kernel 5.9 and QubesOS wants to use memory hotplugging for guests in order to be able to start a guest with minimal memory and expand it as needed. This was the report leading to the patch.

[patch 03/14] mm/secretmem: fix panic when growing a memfd_secret

by Andrew Morton

From: Axel Rasmussen <axelrasmussen(a)google.com> Subject: mm/secretmem: fix panic when growing a memfd_secret When one tries to grow an existing memfd_secret with ftruncate, one gets a panic [1]. For example, doing the following reliably induces the panic: fd = memfd_secret(); ftruncate(fd, 10); ptr = mmap(NULL, 10, PROT_READ | PROT_WRITE, MAP_SHARED, fd, 0); strcpy(ptr, "123456789"); munmap(ptr, 10); ftruncate(fd, 20); The basic reason for this is, when we grow with ftruncate, we call down into simple_setattr, and then truncate_inode_pages_range, and eventually we try to zero part of the memory. The normal truncation code does this via the direct map (i.e., it calls page_address() and hands that to memset()). For memfd_secret though, we specifically don't map our pages via the direct map (i.e. we call set_direct_map_invalid_noflush() on every fault). So the address returned by page_address() isn't useful, and when we try to memset() with it we panic. This patch avoids the panic by implementing a custom setattr for memfd_secret, which detects resizes specifically (setting the size for the first time works just fine, since there are no existing pages to try to zero), and rejects them with EINVAL. One could argue growing should be supported, but I think that will require a significantly more lengthy change. So, I propose a minimal fix for the benefit of stable kernels, and then perhaps to extend memfd_secret to support growing in a separate patch.

[PATCH v3 00/18 stable-5.15.y] Fix mmap + page fault deadlocks

by Anand Jain

v3: Fix the patch order and fix the missing symbol compile error when compiled after each patch is applied. v2: Rebase on the latest stable-5.15.33. Adds the following commits to the v1 patchset as they fix issues in the merged commit. ca93e44bfb5f btrfs: fallback to blocking mode when doing async dio over multiple extents fe673d3f5bf1 mm: gup: make fault_in_safe_writeable() use fixup_user_fault() And this set drops the following patch as it is already in the stable-5.15.y. [PATCH 01/17 stable-5.15.y] powerpc/kvm: Fix kvm_use_magic_page ------- original cover letter -------- This set fixes a process hang issue in btrfs and gf2 filesystems. When we do a direct IO read or write when the buffer given by the user is memory-mapped to the file range we are going to do IO, we end up ending in a deadlock. This is triggered by the test case generic/647 from fstests. This fix depends on the iov_iter and iomap changes introduced in the commit c03098d4b9ad ("Merge tag 'gfs2-v5.15-rc5-mmap-fault' of git://git.kernel.org/pub/scm/linux/kernel/git/gfs2/linux-gfs2") and they are part of this set for stable-5.15.y. Please note that patch 2/18 (in v2) (was 3/17 in v1) in the patchset changes the prototype and renames an exported symbol as below. All its references are updated as well. -EXPORT_SYMBOL(iov_iter_fault_in_readable); +EXPORT_SYMBOL(fault_in_iov_iter_readable); Andreas Gruenbacher (14): gup: Turn fault_in_pages_{readable,writeable} into fault_in_{readable,writeable} iov_iter: Turn iov_iter_fault_in_readable into fault_in_iov_iter_readable iov_iter: Introduce fault_in_iov_iter_writeable gfs2: Add wrapper for iomap_file_buffered_write gfs2: Clean up function may_grant gfs2: Move the inode glock locking to gfs2_file_buffered_write gfs2: Eliminate ip->i_gh gfs2: Fix mmap + page fault deadlocks for buffered I/O iomap: Fix iomap_dio_rw return value for user copies iomap: Support partial direct I/O on user copy failures iomap: Add done_before argument to iomap_dio_rw gup: Introduce FOLL_NOFAULT flag to disable page faults iov_iter: Introduce nofault flag to disable page faults gfs2: Fix mmap + page fault deadlocks for direct I/O Bob Peterson (1): gfs2: Introduce flag for glock holder auto-demotion Filipe Manana (2): btrfs: fix deadlock due to page faults during direct IO reads and writes btrfs: fallback to blocking mode when doing async dio over multiple extents Linus Torvalds (1): mm: gup: make fault_in_safe_writeable() use fixup_user_fault() arch/powerpc/kernel/kvm.c | 3 +- arch/powerpc/kernel/signal_32.c | 4 +- arch/powerpc/kernel/signal_64.c | 2 +- arch/x86/kernel/fpu/signal.c | 7 +- drivers/gpu/drm/armada/armada_gem.c | 7 +- fs/btrfs/file.c | 142 ++++++++++-- fs/btrfs/inode.c | 28 +++ fs/btrfs/ioctl.c | 5 +- fs/erofs/data.c | 2 +- fs/ext4/file.c | 5 +- fs/f2fs/file.c | 2 +- fs/fuse/file.c | 2 +- fs/gfs2/bmap.c | 60 +---- fs/gfs2/file.c | 252 +++++++++++++++++++-- fs/gfs2/glock.c | 330 +++++++++++++++++++++------- fs/gfs2/glock.h | 20 ++ fs/gfs2/incore.h | 4 +- fs/iomap/buffered-io.c | 2 +- fs/iomap/direct-io.c | 29 ++- fs/ntfs/file.c | 2 +- fs/ntfs3/file.c | 2 +- fs/xfs/xfs_file.c | 6 +- fs/zonefs/super.c | 4 +- include/linux/iomap.h | 11 +- include/linux/mm.h | 3 +- include/linux/pagemap.h | 58 +---- include/linux/uio.h | 4 +- lib/iov_iter.c | 98 +++++++-- mm/filemap.c | 4 +- mm/gup.c | 120 +++++++++- 30 files changed, 920 insertions(+), 298 deletions(-) -- 2.33.1
