arm64: mm: fix p?d_leaf()
[ Upstream commit 23bc8f69f0eceecbb87c3801d2e48827d2dca92b ]
The pmd_leaf() is used to test a leaf mapped PMD, however, it misses
the PROT_NONE mapped PMD on arm64. Fix it. A real world issue [1]
caused by this was reported by Qian Cai. Also fix pud_leaf().

arm64/mm: Remove [PUD|PMD]_TABLE_BIT from [pud|pmd]_bad()
[ Upstream commit e377ab82311af95c99648c6424a6b888a0ccb102 ]
Semantics wise, [pud|pmd]_bad() have always implied that a given [PUD|PMD]
entry does not have a pointer to the next level page table. This had been
made clear in the commit

arm64: pgtable: make __pte_to_phys/__phys_to_pte_val inline functions
[ Upstream commit c7c386fbc20262c1d911c615c65db6a58667d92c ]
gcc warns about undefined behavior the vmalloc code when building
with CONFIG_ARM64_PA_BITS_52, when the 'idx++' in the argument to
__phys_to_pte_val() is evaluated twice:
mm/vmalloc.c: In function 'vmap_pfn_apply':
mm/vmalloc.c:2800:58: error: operation on 'data->idx' may be undefined [-Werror=sequence-point]
2800 | *pte = pte_mkspecial(pfn_pte(data->pfns[data->idx++], data->prot));
| ~~~~~~~~~^~
arch/arm64/include/asm/pgtable-types.h:25:37: note: in definition of macro '__pte'
25 | #define __pte(x) ((pte_t) { (x) } )
| ^
arch/arm64/include/asm/pgtable.h:80:15: note: in expansion of macro '__phys_to_pte_val'
80 | __pte(__phys_to_pte_val((phys_addr_t)(pfn) << PAGE_SHIFT) | pgprot_val(prot))
| ^~~~~~~~~~~~~~~~~
mm/vmalloc.c:2800:30: note: in expansion of macro 'pfn_pte'
2800 | *pte = pte_mkspecial(pfn_pte(data->pfns[data->idx++], data->prot));
| ^~~~~~~
I have no idea why this never showed up earlier, but the safest
workaround appears to be changing those macros into inline functions
so the arguments get evaluated only once.

arm64: consistently use reserved_pg_dir
[ Upstream commit 833be850f1cabd0e3b5337c0fcab20a6e936dd48 ] Depending on configuration options and specific code paths, we either use the empty_zero_page or the configuration-dependent reserved_ttbr0 as a reserved value for TTBR{0,1}_EL1. To simplify this code, let's always allocate and use the same reserved_pg_dir, replacing reserved_ttbr0. Note that this is allocated (and hence pre-zeroed), and is also marked as read-only in the kernel Image mapping. Keeping this separate from the empty_zero_page potentially helps with robustness as the empty_zero_page is used in a number of cases where a failure to map it read-only could allow it to become corrupted. The (presently unused) swapper_pg_end symbol is also removed, and comments are added wherever we rely on the offsets between the pre-allocated pg_dirs to keep these cases easily identifiable.

arm64: mte: Map hotplugged memory as Normal Tagged
commit d15dfd31384ba3cb93150e5f87661a76fa419f74 upstream.

On CPUs with hardware AF/DBM, initialising prefaulted PTEs as 'old' improves vmscan behaviour and does not appear to introduce any overhead elsewhere.

UPSTREAM: arm64: mremap speedup - enable HAVE_MOVE_PUD
HAVE_MOVE_PUD enables remapping pages at the PUD level if both the source and destination addresses are PUD-aligned. With HAVE_MOVE_PUD enabled it can be inferred that there is approximately a 19x improvement in performance on arm64. (See data below). ------- Test Results --------- The following results were obtained using a 5.4 kernel, by remapping a PUD-aligned, 1GB sized region to a PUD-aligned destination.

ANDROID: arm64: Add support for system cache memory type
Non-coherent devices on systems that support a system or last level cache may want to request that allocations be cached in the system cache. For memory that is allocated by the kernel, and used for DMA with devices, the memory attributes used for CPU access should match the memory attributes that will be used for device access. The memory attributes that need to be programmed into the MAIR for system cache usage are: 0xf4 - Normal memory, outer write back read/write allocate, inner non-cacheable. There is currently no support for this memory attribute for CPU mappings, so add it. Bug: 176778547 Change-Id: I3abc7becd408f20ac5499cbbe3c6c6f53f784107 Signed-off-by: Isaac J.

After certain memory blocks are offlined, some usecases require that the page-table mappings are removed while still keeping the memblock device nodes, memory resources and the memmap entries intact. This is to avoid the overhead involved in using 'remove_memory' if the offlined blocks will be added/onlined back into the system at later point. {populate/depopulate}_range_driver_managed provide the abilty to drivers to tear-down and create page-table mappings of memory blocks that its managing, without having to use 'remove_memory' and friends for the purpose. These functions does not interfere with mappings of boot memory or resources that isn't owned by the driver.

arm64: pgtable: Ensure dirty bit is preserved across pte_wrprotect()
With hardware dirty bit management, calling pte_wrprotect() on a writable,
dirty PTE will lose the dirty state and return a read-only, clean entry.
Move the logic from ptep_set_wrprotect() into pte_wrprotect() to ensure that
the dirty bit is preserved for writable entries, as this is required for
soft-dirty bit management if we enable it in the future.

arm64: pgtable: Fix pte_accessible()
pte_accessible() is used by ptep_clear_flush() to figure out whether TLB
invalidation is necessary when unmapping pages for reclaim. Although our
implementation is correct according to the architecture, returning true
only for valid, young ptes in the absence of racing page-table
modifications, this is in fact flawed due to lazy invalidation of old
ptes in ptep_clear_flush_young() where we elide the expensive DSB
instruction for completing the TLB invalidation.
Rather than penalise the aging path, adjust pte_accessible() to return
true for any valid pte, even if the access flag is cleared.

arm64: mm: use single quantity to represent the PA to VA translation
On arm64, the global variable memstart_addr represents the physical
address of PAGE_OFFSET, and so physical to virtual translations or
vice versa used to come down to simple additions or subtractions
involving the values of PAGE_OFFSET and memstart_addr.
When support for 52-bit virtual addressing was introduced, we had to
deal with PAGE_OFFSET potentially being outside of the region that
can be covered by the virtual range (as the 52-bit VA capable build
needs to be able to run on systems that are only 48-bit VA capable),
and for this reason, another translation was introduced, and recorded
in the global variable physvirt_offset.
However, if we go back to the original definition of memstart_addr,
i.e., the physical address of PAGE_OFFSET, it turns out that there is
no need for two separate translations: instead, we can simply subtract
the size of the unaddressable VA space from memstart_addr to make the
available physical memory appear in the 48-bit addressable VA region.
This simplifies things, but also fixes a bug on KASLR builds, which
may update memstart_addr later on in arm64_memblock_init(), but fails
to update vmemmap and physvirt_offset accordingly.

arm64/mm: Refactor {pgd, pud, pmd, pte}_ERROR()
The function __{pgd, pud, pmd, pte}_error() are introduced so that they can be called by {pgd, pud, pmd, pte}_ERROR(). However, some of the functions could never be called when the corresponding page table level isn't enabled. For example, __{pud, pmd}_error() are unused when PUD and PMD are folded to PGD. This removes __{pgd, pud, pmd, pte}_error() and call pr_err() from {pgd, pud, pmd, pte}_ERROR() directly, similar to what x86/powerpc are doing. With this, the code looks a bit simplified either.

arm64/mm: Enable THP migration
In certain page migration situations, a THP page can be migrated without being split into it's constituent subpages. This saves time required to split a THP and put it back together when required. But it also saves an wider address range translation covered by a single TLB entry, reducing future page fault costs. A previous patch changed platform THP helpers per generic memory semantics, clearing the path for THP migration support. This adds two more THP helpers required to create PMD migration swap entries. Now enable THP migration via ARCH_ENABLE_THP_MIGRATION.

arm64/mm: Change THP helpers to comply with generic MM semantics
pmd_present() and pmd_trans_huge() are expected to behave in the following manner during various phases of a given PMD. It is derived from a previous detailed discussion on this topic [1] and present THP documentation [2]. pmd_present(pmd): - Returns true if pmd refers to system RAM with a valid pmd_page(pmd) - Returns false if pmd refers to a migration or swap entry pmd_trans_huge(pmd): - Returns true if pmd refers to system RAM and is a trans huge mapping ------------------------------------------------------------------------- | PMD states | pmd_present | pmd_trans_huge | ------------------------------------------------------------------------- | Mapped | Yes | Yes | ------------------------------------------------------------------------- | Splitting | Yes | Yes | ------------------------------------------------------------------------- | Migration/Swap | No | No | ------------------------------------------------------------------------- The problem: PMD is first invalidated with pmdp_invalidate() before it's splitting. This invalidation clears PMD_SECT_VALID as below. PMD Split -> pmdp_invalidate() -> pmd_mkinvalid -> Clears PMD_SECT_VALID Once PMD_SECT_VALID gets cleared, it results in pmd_present() return false on the PMD entry. It will need another bit apart from PMD_SECT_VALID to re- affirm pmd_present() as true during the THP split process. To comply with above mentioned semantics, pmd_trans_huge() should also check pmd_present() first before testing presence of an actual transparent huge mapping. The solution: Ideally PMD_TYPE_SECT should have been used here instead. But it shares the bit position with PMD_SECT_VALID which is used for THP invalidation. Hence it will not be there for pmd_present() check after pmdp_invalidate(). A new software defined PMD_PRESENT_INVALID (bit 59) can be set on the PMD entry during invalidation which can help pmd_present() return true and in recognizing the fact that it still points to memory. This bit is transient. During the split process it will be overridden by a page table page representing normal pages in place of erstwhile huge page. Other pmdp_invalidate() callers always write a fresh PMD value on the entry overriding this transient PMD_PRESENT_INVALID bit, which makes it safe.

When swapping pages out to disk it is necessary to save any tags that have been set, and restore when swapping back in. Make use of the new page flag (PG_ARCH_2, locally named PG_mte_tagged) to identify pages with tags. When swapping out these pages the tags are stored in memory and later restored when the pages are brought back in. Because shmem can swap pages back in without restoring the userspace PTE it is also necessary to add a hook for shmem.

arm64: mte: Add PROT_MTE support to mmap() and mprotect()
To enable tagging on a memory range, the user must explicitly opt in via a new PROT_MTE flag passed to mmap() or mprotect(). Since this is a new memory type in the AttrIndx field of a pte, simplify the or'ing of these bits over the protection_map[] attributes by making MT_NORMAL index 0. There are two conditions for arch_vm_get_page_prot() to return the MT_NORMAL_TAGGED memory type: (1) the user requested it via PROT_MTE, registered as VM_MTE in the vm_flags, and (2) the vma supports MTE, decided during the mmap() call (only) and registered as VM_MTE_ALLOWED. arch_calc_vm_prot_bits() is responsible for registering the user request as VM_MTE. The newly introduced arch_calc_vm_flag_bits() sets VM_MTE_ALLOWED if the mapping is MAP_ANONYMOUS. An MTE-capable filesystem (RAM-based) may be able to set VM_MTE_ALLOWED during its mmap() file ops call. In addition, update VM_DATA_DEFAULT_FLAGS to allow mprotect(PROT_MTE) on stack or brk area. The Linux mmap() syscall currently ignores unknown PROT_* flags. In the presence of MTE, an mmap(PROT_MTE) on a file which does not support MTE will not report an error and the memory will not be mapped as Normal Tagged. For consistency, mprotect(PROT_MTE) will not report an error either if the memory range does not support MTE. Two subsequent patches in the series will propose tightening of this behaviour.

arm64: mte: Clear the tags when a page is mapped in user-space with PROT_MTE
Pages allocated by the kernel are not guaranteed to have the tags zeroed, especially as the kernel does not (yet) use MTE itself. To ensure the user can still access such pages when mapped into its address space, clear the tags via set_pte_at().

mm: consolidate pte_index() and pte_offset_*() definitions
All architectures define pte_index() as (address >> PAGE_SHIFT) & (PTRS_PER_PTE - 1) and all architectures define pte_offset_kernel() as an entry in the array of PTEs indexed by the pte_index(). For the most architectures the pte_offset_kernel() implementation relies on the availability of pmd_page_vaddr() that converts a PMD entry value to the virtual address of the page containing PTEs array. Let's move x86 definitions of the PTE accessors to the generic place in <linux/pgtable.h> and then simply drop the respective definitions from the other architectures. The architectures that didn't provide pmd_page_vaddr() are updated to have that defined. The generic implementation of pte_offset_kernel() can be overridden by an architecture and alpha makes use of this because it has special ordering requirements for its version of pte_offset_kernel().

mm/thp: rename pmd_mknotpresent() as pmd_mkinvalid()
pmd_present() is expected to test positive after pmdp_mknotpresent() as the PMD entry still points to a valid huge page in memory. pmdp_mknotpresent() implies that given PMD entry is just invalidated from MMU perspective while still holding on to pmd_page() referred valid huge page thus also clearing pmd_present() test. This creates the following situation which is counter intuitive. [pmd_present(pmd_mknotpresent(pmd)) = true] This renames pmd_mknotpresent() as pmd_mkinvalid() reflecting the helper's functionality more accurately while changing the above mentioned situation as follows. This does not create any functional change. [pmd_present(pmd_mkinvalid(pmd)) = true] This is not applicable for platforms that define own pmdp_invalidate() via __HAVE_ARCH_PMDP_INVALIDATE. Suggestion for renaming came during a previous discussion here. https://patchwork.kernel.org/patch/11019637/ [anshuman.khandual@arm.com: change pmd_mknotvalid() to pmd_mkinvalid() per Will] Link: http://lkml.kernel.org/r/1587520326-10099-3-git-send-email-anshuman.khandual@arm.com Suggested-by: Catalin Marinas <catalin.marinas@arm.com> Signed-off-by: Anshuman Khandual <anshuman.khandual@arm.com> Signed-off-by: Andrew Morton <akpm@linux-foundation.org> Acked-by: Will Deacon <will@kernel.org> Cc: Vineet Gupta <vgupta@synopsys.com> Cc: Russell King <linux@armlinux.org.uk> Cc: Catalin Marinas <catalin.marinas@arm.com> Cc: Thomas Bogendoerfer <tsbogend@alpha.franken.de> Cc: Thomas Gleixner <tglx@linutronix.de> Cc: Ingo Molnar <mingo@redhat.com> Cc: Borislav Petkov <bp@alien8.de> Cc: "H.

arm64/mm: Use phys_to_page() to access pgtable memory
The macros {pgd, pud, pmd}_page() retrieves the page struct of the corresponding page frame, which is reserved as page table. There is already a macro (phys_to_page), defined in memory.h as below, to convert the physical address to the page struct. Also, the header file (memory.h) has been included by pgtable.h. #define phys_to_page(phys) (pfn_to_page(__phys_to_pfn(phys))) So it's reasonable to use the macro in pgtable.h.

arm64: Basic Branch Target Identification support
This patch adds the bare minimum required to expose the ARMv8.5 Branch Target Identification feature to userspace. By itself, this does _not_ automatically enable BTI for any initial executable pages mapped by execve(). This will come later, but for now it should be possible to enable BTI manually on those pages by using mprotect() from within the target process. Other arches already using the generic mman.h are already using 0x10 for arch-specific prot flags, so we use that for PROT_BTI here. For consistency, signal handler entry points in BTI guarded pages are required to be annotated as such, just like any other function. This blocks a relatively minor attack vector, but comforming userspace will have the annotations anyway, so we may as well enforce them.

arm64: mm: add p?d_leaf() definitions
walk_page_range() is going to be allowed to walk page tables other than those of user space. For this it needs to know when it has reached a 'leaf' entry in the page tables. This information will be provided by the p?d_leaf() functions/macros. For arm64, we already have p?d_sect() macros which we can reuse for p?d_leaf(). pud_sect() is defined as a dummy function when CONFIG_PGTABLE_LEVELS < 3 or CONFIG_ARM64_64K_PAGES is defined. However when the kernel is configured this way then architecturally it isn't allowed to have a large page at this level, and any code using these page walking macros is implicitly relying on the page size/number of levels being the same as the kernel. So it is safe to reuse this for p?d_leaf() as it is an architectural restriction.

arm64: Revert support for execute-only user mappings
The ARMv8 64-bit architecture supports execute-only user permissions by clearing the PTE_USER and PTE_UXN bits, practically making it a mostly privileged mapping but from which user running at EL0 can still execute. The downside, however, is that the kernel at EL1 inadvertently reading such mapping would not trip over the PAN (privileged access never) protection. Revert the relevant bits from commit |

arm64: mm: implement arch_faults_on_old_pte() on arm64
On arm64 without hardware Access Flag, copying from user will fail because the pte is old and cannot be marked young. So we always end up with zeroed page after fork() + CoW for pfn mappings. We don't always have a hardware-managed Access Flag on arm64. Hence implement arch_faults_on_old_pte on arm64 to indicate that it might cause page fault when accessing old pte.

arm64: Fix kcore macros after 52-bit virtual addressing fallout
We export the entire kernel address space (i.e. the whole of the TTBR1 address range) via /proc/kcore. The kc_vaddr_to_offset() and kc_offset_to_vaddr() macros are intended to convert between a kernel virtual address and its offset relative to the start of the TTBR1 address space. Prior to commit: |

mm: consolidate pgtable_cache_init() and pgd_cache_init()
Both pgtable_cache_init() and pgd_cache_init() are used to initialize kmem cache for page table allocations on several architectures that do not use PAGE_SIZE tables for one or more levels of the page table hierarchy. Most architectures do not implement these functions and use __weak default NOP implementation of pgd_cache_init(). Since there is no such default for pgtable_cache_init(), its empty stub is duplicated among most architectures. Rename the definitions of pgd_cache_init() to pgtable_cache_init() and drop empty stubs of pgtable_cache_init().

Merge tag 'arm64-upstream' of git://git.kernel.org/pub/scm/linux/kernel/git/arm64/linux
Pull arm64 updates from Will Deacon: "Although there isn't tonnes of code in terms of line count, there are a fair few headline features which I've noted both in the tag and also in the merge commits when I pulled everything together. The part I'm most pleased with is that we had 35 contributors this time around, which feels like a big jump from the usual small group of core arm64 arch developers. Hopefully they all enjoyed it so much that they'll continue to contribute, but we'll see. It's probably worth highlighting that we've pulled in a branch from the risc-v folks which moves our CPU topology code out to where it can be shared with others. Summary: - 52-bit virtual addressing in the kernel - New ABI to allow tagged user pointers to be dereferenced by syscalls - Early RNG seeding by the bootloader - Improve robustness of SMP boot - Fix TLB invalidation in light of recent architectural clarifications - Support for i.MX8 DDR PMU - Remove direct LSE instruction patching in favour of static keys - Function error injection using kprobes - Support for the PPTT "thread" flag introduced by ACPI 6.3 - Move PSCI idle code into proper cpuidle driver - Relaxation of implicit I/O memory barriers - Build with RELR relocations when toolchain supports them - Numerous cleanups and non-critical fixes" * tag 'arm64-upstream' of git://git.kernel.org/pub/scm/linux/kernel/git/arm64/linux: (114 commits) arm64: remove __iounmap arm64: atomics: Use K constraint when toolchain appears to support it arm64: atomics: Undefine internal macros after use arm64: lse: Make ARM64_LSE_ATOMICS depend on JUMP_LABEL arm64: asm: Kill 'asm/atomic_arch.h' arm64: lse: Remove unused 'alt_lse' assembly macro arm64: atomics: Remove atomic_ll_sc compilation unit arm64: avoid using hard-coded registers for LSE atomics arm64: atomics: avoid out-of-line ll/sc atomics arm64: Use correct ll/sc atomic constraints jump_label: Don't warn on __exit jump entries docs/perf: Add documentation for the i.MX8 DDR PMU perf/imx_ddr: Add support for AXI ID filtering arm64: kpti: ensure patched kernel text is fetched from PoU arm64: fix fixmap copy for 16K pages and 48-bit VA perf/smmuv3: Validate groups for global filtering perf/smmuv3: Validate group size arm64: Relax Documentation/arm64/tagged-pointers.rst arm64: kvm: Replace hardcoded '1' with SYS_PAR_EL1_F arm64: mm: Ignore spurious translation faults taken from the kernel ... |
