mm: fix race by making init_zero_pfn() early_initcall
commit e720e7d0e983bf05de80b231bccc39f1487f0f16 upstream.
There are code paths that rely on zero_pfn to be fully initialized
before core_initcall. For example, wq_sysfs_init() is a core_initcall
function that eventually results in a call to kernel_execve, which
causes a page fault with a subsequent mmput. If zero_pfn is not
initialized by then it may not get cleaned up properly and result in an
error:
BUG: Bad rss-counter state mm:(ptrval) type:MM_ANONPAGES val:1
Here is an analysis of the race as seen on a MIPS device. On this
particular MT7621 device (Ubiquiti ER-X), zero_pfn is PFN 0 until
initialized, at which point it becomes PFN 5120:
1. wq_sysfs_init calls into kobject_uevent_env at core_initcall:
kobject_uevent_env+0x7e4/0x7ec
kset_register+0x68/0x88
bus_register+0xdc/0x34c
subsys_virtual_register+0x34/0x78
wq_sysfs_init+0x1c/0x4c
do_one_initcall+0x50/0x1a8
kernel_init_freeable+0x230/0x2c8
kernel_init+0x10/0x100
ret_from_kernel_thread+0x14/0x1c
2. kobject_uevent_env() calls call_usermodehelper_exec() which executes
kernel_execve asynchronously.
3. Memory allocations in kernel_execve cause a page fault, bumping the
MM reference counter:
add_mm_counter_fast+0xb4/0xc0
handle_mm_fault+0x6e4/0xea0
__get_user_pages.part.78+0x190/0x37c
__get_user_pages_remote+0x128/0x360
get_arg_page+0x34/0xa0
copy_string_kernel+0x194/0x2a4
kernel_execve+0x11c/0x298
call_usermodehelper_exec_async+0x114/0x194
4. In case zero_pfn has not been initialized yet, zap_pte_range does
not decrement the MM_ANONPAGES RSS counter and the BUG message is
triggered shortly afterwards when __mmdrop checks the ref counters:
__mmdrop+0x98/0x1d0
free_bprm+0x44/0x118
kernel_execve+0x160/0x1d8
call_usermodehelper_exec_async+0x114/0x194
ret_from_kernel_thread+0x14/0x1c
To avoid races such as described above, initialize init_zero_pfn at
early_initcall level. Depending on the architecture, ZERO_PAGE is
either constant or gets initialized even earlier, at paging_init, so
there is no issue with initializing zero_pfn earlier.

mm/userfaultfd: fix memory corruption due to writeprotect
commit 6ce64428d62026a10cb5d80138ff2f90cc21d367 upstream. Userfaultfd self-test fails occasionally, indicating a memory corruption. Analyzing this problem indicates that there is a real bug since mmap_lock is only taken for read in mwriteprotect_range() and defers flushes, and since there is insufficient consideration of concurrent deferred TLB flushes in wp_page_copy(). Although the PTE is flushed from the TLBs in wp_page_copy(), this flush takes place after the copy has already been performed, and therefore changes of the page are possible between the time of the copy and the time in which the PTE is flushed. To make matters worse, memory-unprotection using userfaultfd also poses a problem. Although memory unprotection is logically a promotion of PTE permissions, and therefore should not require a TLB flush, the current userrfaultfd code might actually cause a demotion of the architectural PTE permission: when userfaultfd_writeprotect() unprotects memory region, it unintentionally *clears* the RW-bit if it was already set. Note that this unprotecting a PTE that is not write-protected is a valid use-case: the userfaultfd monitor might ask to unprotect a region that holds both write-protected and write-unprotected PTEs. The scenario that happens in selftests/vm/userfaultfd is as follows: cpu0 cpu1 cpu2 ---- ---- ---- [ Writable PTE cached in TLB ] userfaultfd_writeprotect() [ write-*unprotect* ] mwriteprotect_range() mmap_read_lock() change_protection() change_protection_range() ... change_pte_range() [ *clear* “write”-bit ] [ defer TLB flushes ] [ page-fault ] ... wp_page_copy() cow_user_page() [ copy page ] [ write to old page ] ... set_pte_at_notify() A similar scenario can happen: cpu0 cpu1 cpu2 cpu3 ---- ---- ---- ---- [ Writable PTE cached in TLB ] userfaultfd_writeprotect() [ write-protect ] [ deferred TLB flush ] userfaultfd_writeprotect() [ write-unprotect ] [ deferred TLB flush] [ page-fault ] wp_page_copy() cow_user_page() [ copy page ] ... [ write to page ] set_pte_at_notify() This race exists since commit |

hugetlb: fix copy_huge_page_from_user contig page struct assumption
commit 3272cfc2525b3a2810a59312d7a1e6f04a0ca3ef upstream.
page structs are not guaranteed to be contiguous for gigantic pages. The
routine copy_huge_page_from_user can encounter gigantic pages, yet it
assumes page structs are contiguous when copying pages from user space.
Since page structs for the target gigantic page are not contiguous, the
data copied from user space could overwrite other pages not associated
with the gigantic page and cause data corruption.
Non-contiguous page structs are generally not an issue. However, they can
exist with a specific kernel configuration and hotplug operations. For
example: Configure the kernel with CONFIG_SPARSEMEM and
!CONFIG_SPARSEMEM_VMEMMAP. Then, hotplug add memory for the area where
the gigantic page will be allocated.

mm: provide a saner PTE walking API for modules
commit 9fd6dad1261a541b3f5fa7dc5b152222306e6702 upstream. Currently, the follow_pfn function is exported for modules but follow_pte is not. However, follow_pfn is very easy to misuse, because it does not provide protections (so most of its callers assume the page is writable!) and because it returns after having already unlocked the page table lock. Provide instead a simplified version of follow_pte that does not have the pmdpp and range arguments. The older version survives as follow_invalidate_pte() for use by fs/dax.c.

commit 7336375734d65ecc82956b59a79cf5deccce880c upstream. Patch series "simplify follow_pte a bit". This small series drops the not needed follow_pte_pmd exports, and simplifies the follow_pte family of functions a bit. This patch (of 2): follow_pte_pmd() is only used by the DAX code, which can't be modular.

BACKPORT: FROMGIT: mm: Pass 'address' to map to do_set_pte() and drop FAULT_FLAG_PREFAULT
Rather than modifying the 'address' field of the 'struct vm_fault' passed to do_set_pte(), leave that to identify the real faulting address and pass in the virtual address to be mapped by the new pte as a separate argument. This makes FAULT_FLAG_PREFAULT redundant, as a prefault entry can be identified simply by comparing the new address parameter with the faulting address, so remove the redundant flag at the same time.

BACKPORT: FROMGIT: mm: Cleanup faultaround and finish_fault() codepaths
alloc_set_pte() has two users with different requirements: in the faultaround code, it called from an atomic context and PTE page table has to be preallocated. finish_fault() can sleep and allocate page table as needed. PTL locking rules are also strange, hard to follow and overkill for finish_fault(). Let's untangle the mess. alloc_set_pte() has gone now. All locking is explicit. The price is some code duplication to handle huge pages in faultaround path, but it should be fine, having overall improvement in readability.

ANDROID: mm: Fix sleeping while atomic during speculative page fault
A speculative page fault may race with a call to free_pagetables. If free_pagetables is called first, *(vmf->pmd) may be empty. __might_sleep() __alloc_pages_nodemask() pte_alloc_one(inline) __pte_alloc() pte_alloc_one_map(inline) alloc_set_pte() filemap_map_pages() do_fault_around(inline) do_read_fault(inline) do_fault(inline) handle_pte_fault() mem_cgroup_exit_user_fault(inline) __handle_speculative_fault() do_page_fault() As filemap_map_pages() holds an rcu_lock(), this triggers a sleeping-while-atomic BUG(). As free_pagetables has already been called, it is also a memory leak. Fix this by skipping to pte_map_lock() to allow spf to detect that the vma has changed, and a normal page fault should be taken instead.

FROMLIST: mm: don't do swap readahead during speculative page fault
Vinayak Menon faced a panic because one thread was page faulting a page in swap, while another one was mprotecting a part of the VMA leading to a VMA split. This raise a panic in swap_vma_readahead() because the VMA's boundaries were not more matching the faulting address. To avoid this, if the page is not found in the swap, the speculative page fault is aborted to retry a regular page fault.

FROMLIST: mm: speculative page fault handler return VMA
When the speculative page fault handler is returning VM_RETRY, there is a chance that VMA fetched without grabbing the mmap_sem can be reused by the legacy page fault handler. By reusing it, we avoid calling find_vma() again. To achieve, that we must ensure that the VMA structure will not be freed in our back. This is done by getting the reference on it (get_vma()) and by assuming that the caller will call the new service can_reuse_spf_vma() once it has grabbed the mmap_sem. can_reuse_spf_vma() is first checking that the VMA is still in the RB tree , and then that the VMA's boundaries matched the passed address and release the reference on the VMA so that it can be freed if needed. In the case the VMA is freed, can_reuse_spf_vma() will have returned false as the VMA is no more in the RB tree. In the architecture page fault handler, the call to the new service reuse_spf_or_find_vma() should be made in place of find_vma(), this will handle the check on the spf_vma and if needed call find_vma().

FROMLIST: mm: provide speculative fault infrastructure
Provide infrastructure to do a speculative fault (not holding mmap_sem). The not holding of mmap_sem means we can race against VMA change/removal and page-table destruction. We use the SRCU VMA freeing to keep the VMA around. We use the VMA seqcount to detect change (including umapping / page-table deletion) and we use gup_fast() style page-table walking to deal with page-table races. Once we've obtained the page and are ready to update the PTE, we validate if the state we started the fault with is still valid, if not, we'll fail the fault with VM_FAULT_RETRY, otherwise we update the PTE and we're done.

FROMLIST: mm: introduce __page_add_new_anon_rmap()
When dealing with speculative page fault handler, we may race with VMA being split or merged. In this case the vma->vm_start and vm->vm_end fields may not match the address the page fault is occurring. This can only happens when the VMA is split but in that case, the anon_vma pointer of the new VMA will be the same as the original one, because in __split_vma the new->anon_vma is set to src->anon_vma when *new = *vma. So even if the VMA boundaries are not correct, the anon_vma pointer is still valid. If the VMA has been merged, then the VMA in which it has been merged must have the same anon_vma pointer otherwise the merge can't be done. So in all the case we know that the anon_vma is valid, since we have checked before starting the speculative page fault that the anon_vma pointer is valid for this VMA and since there is an anon_vma this means that at one time a page has been backed and that before the VMA is cleaned, the page table lock would have to be grab to clean the PTE, and the anon_vma field is checked once the PTE is locked. This patch introduce a new __page_add_new_anon_rmap() service which doesn't check for the VMA boundaries, and create a new inline one which do the check. When called from a page fault handler, if this is not a speculative one, there is a guarantee that vm_start and vm_end match the faulting address, so this check is useless. In the context of the speculative page fault handler, this check may be wrong but anon_vma is still valid as explained above.

FROMLIST: mm: introduce __vm_normal_page()
When dealing with the speculative fault path we should use the VMA's field cached value stored in the vm_fault structure. Currently vm_normal_page() is using the pointer to the VMA to fetch the vm_flags value. This patch provides a new __vm_normal_page() which is receiving the vm_flags flags value as parameter. Note: The speculative path is turned on for architecture providing support for special PTE flag. So only the first block of vm_normal_page is used during the speculative path.

FROMLIST: mm: protect SPF handler against anon_vma changes
The speculative page fault handler must be protected against anon_vma changes. This is because page_add_new_anon_rmap() is called during the speculative path. In addition, don't try speculative page fault if the VMA don't have an anon_vma structure allocated because its allocation should be protected by the mmap_sem. In __vma_adjust() when importer->anon_vma is set, there is no need to protect against speculative page faults since speculative page fault is aborted if the vma->anon_vma is not set. When calling page_add_new_anon_rmap() vma->anon_vma is necessarily valid since we checked for it when locking the pte and the anon_vma is removed once the pte is unlocked. So even if the speculative page fault handler is running concurrently with do_unmap(), as the pte is locked in unmap_region() - through unmap_vmas() - and the anon_vma unlinked later, because we check for the vma sequence counter which is updated in unmap_page_range() before locking the pte, and then in free_pgtables() so when locking the pte the change will be detected.

FROMLIST: mm: VMA sequence count
Wrap the VMA modifications (vma_adjust/unmap_page_range) with sequence counts such that we can easily test if a VMA is changed. The unmap_page_range() one allows us to make assumptions about page-tables; when we find the seqcount hasn't changed we can assume page-tables are still valid. The flip side is that we cannot distinguish between a vma_adjust() and the unmap_page_range() -- where with the former we could have re-checked the vma bounds against the address.

FROMLIST: mm: make pte_unmap_same compatible with SPF
pte_unmap_same() is making the assumption that the page table are still around because the mmap_sem is held. This is no more the case when running a speculative page fault and additional check must be made to ensure that the final page table are still there. This is now done by calling pte_spinlock() to check for the VMA's consistency while locking for the page tables. This is requiring passing a vm_fault structure to pte_unmap_same() which is containing all the needed parameters. As pte_spinlock() may fail in the case of a speculative page fault, if the VMA has been touched in our back, pte_unmap_same() should now return 3 cases : 1. pte are the same (0) 2. pte are different (VM_FAULT_PTNOTSAME) 3. a VMA's changes has been detected (VM_FAULT_RETRY) The case 2 is handled by the introduction of a new VM_FAULT flag named VM_FAULT_PTNOTSAME which is then trapped in cow_user_page(). If VM_FAULT_RETRY is returned, it is passed up to the callers to retry the page fault while holding the mmap_sem.

ANDROID: mm: Create vendor hooks to control ZONE_MOVABLE allocations
Create a vendor hook inside of gfp_zone() to modify which allocations get to enter ZONE_MOVABLE, by zeroing out __GFP_HIGHMEM inside of the trace hook based on certain conditions. Separately, create separate trace hooks in the swap-in and readahead paths to affect the behavior of the tracehook in gfp_zone().

mm: allow a NULL fn callback in apply_to_page_range
Besides calling the callback on each page, apply_to_page_range also has the effect of pre-faulting all PTEs for the range. To support callers that only need the pre-faulting, make the callback optional. Based on a patch from Minchan Kim <minchan@kernel.org>.
