      x86: uaccess: move 32-bit and 64-bit parts into proper <asm/uaccess_N.h> header · b9bd9f60
      Linus Torvalds authored
      The x86 <asm/uaccess.h> file has grown features that are specific to
      x86-64 like LAM support and the related access_ok() changes.  They
      really should be in the <asm/uaccess_64.h> file and not pollute the
      generic x86 header.

      x86: mm: remove architecture-specific 'access_ok()' define · 6ccdc91d
      Linus Torvalds authored
      There's already a generic definition of 'access_ok()' in the
      asm-generic/access_ok.h header file, and the only difference bwteen that
      and the x86-specific one is the added check for WARN_ON_IN_IRQ().
      
      And it turns out that the reason for that check is long gone: it used to
      use a "user_addr_max()" inline function that depended on the current
      thread, and caused problems in non-thread contexts.
      
      For details, see commits 7c478895 ("x86/uaccess, sched/preempt:
      Verify access_ok() context") and in particular commit ae31fe51
      ("perf/x86: Restore TASK_SIZE check on frame pointer") about how and why
      this came to be.
      
      But that "current task" issue was removed in the big set_fs() removal by
      Christoph Hellwig in commit 47058bb5 ("x86: remove address space
      overrides using set_fs()").
      
      So the reason for the test and the architecture-specific access_ok()
      define no longer exists, and is actually harmful these days.  For
      example, it led various 'copy_from_user_nmi()' games (eg using
      __range_not_ok() instead, and then later converted to __access_ok() when
      that became ok).
      
      And that in turn meant that LAM was broken for the frame following
      before this series, because __access_ok() used to not do the address
      untagging.
      
      Accessing user state still needs care in many contexts, but access_ok()
      is not the place for this test.

      x86-64: make access_ok() independent of LAM · 6014bc27
      Linus Torvalds authored
      The linear address masking (LAM) code made access_ok() more complicated,
      in that it now needs to untag the address in order to verify the access
      range.  See commit 74c228d2 ("x86/uaccess: Provide untagged_addr()
      and remove tags before address check").
      
      We were able to avoid that overhead in the get_user/put_user code paths
      by simply using the sign bit for the address check, and depending on the
      GP fault if the address was non-canonical, which made it all independent
      of LAM.
      
      And we can do the same thing for access_ok(): simply check that the user
      pointer range has the high bit clear.  No need to bother with any
      address bit masking.
      
      In fact, we can go a bit further, and just check the starting address
      for known small accesses ranges: any accesses that overflow will still
      be in the non-canonical area and will still GP fault.
      
      To still make syzkaller catch any potentially unchecked user addresses,
      we'll continue to warn about GP faults that are caused by accesses in
      the non-canonical range.  But we'll limit that to purely "high bit set
      and past the one-page 'slop' area".
      
      We could probably just do that "check only starting address" for any
      arbitrary range size: realistically all kernel accesses to user space
      will be done starting at the low address.  But let's leave that kind of
      optimization for later.  As it is, this already allows us to generate
      simpler code and not worry about any tag bits in the address.
      
      The one thing to look out for is the GUP address check: instead of
      actually copying data in the virtual address range (and thus bad
      addresses being caught by the GP fault), GUP will look up the page
      tables manually.  As a result, the page table limits need to be checked,
      and that was previously implicitly done by the access_ok().
      
      With the relaxed access_ok() check, we need to just do an explicit check
      for TASK_SIZE_MAX in the GUP code instead.  The GUP code already needs
      to do the tag bit unmasking anyway, so there this is all very
      straightforward, and there are no LAM issues.

      Pull pin control updates from Linus Walleij:
       "Mostly drivers! Nothing special: some new Qualcomm chips as usual, and
        the new NXP S32 and nVidia BlueField-3.
      
        Core changes:
      
         - Make a lot of pin controllers with GPIO and irqchips immutable,
           i.e. not living structs, but const structs. This is driving a
           changed initiated by the irqchip maintainers.
      
        New drivers:
      
         - New driver for the NXP S32 SoC pin controller
      
         - As part of a thorough cleanup and restructuring of the
           Ralink/Mediatek drivers, the Ralink MIPS pin control drivers were
           folded into the Mediatek directory and the family is renamed
           "mtmips". The Ralink chips live on as Mediatek MIPS family where
           new variants can be added. As part of this work also the device
           tree bindings were reworked.
      
         - New subdriver for the Qualcomm SM7150 SoC.
      
         - New subdriver for the Qualcomm IPQ9574 SoC.
      
         - New driver for the nVidia BlueField-3 SoC.
      
         - Support for the Qualcomm PMM8654AU mixed signal circuit GPIO.
      
         - Support for the Qualcomm PMI632 mixed signal circuit GPIO.
      
        Improvements:
      
         - Add some missing pins and generic cleanups on the Renesas r8a779g0
           and r8a779g0 pin controllers. Generic Renesas extension for power
           source selection on several SoCs.
      
         - Misc cleanups for the Atmel AT91 and AT91-PIO4 pin controllers
      
         - Make the GPIO mode work on the Qualcomm SM8550-lpass-lpi driver.
      
         - Several device tree binding cleanups as the binding YAML syntax is
           solidifying"

      afs: Avoid endless loop if file is larger than expected · 9ea4eff4
      Marc Dionne authored
      afs_read_dir fetches an amount of data that's based on what the inode
      size is thought to be.  If the file on the server is larger than what
      was fetched, the code rechecks i_size and retries.  If the local i_size
      was not properly updated, this can lead to an endless loop of fetching
      i_size from the server and noticing each time that the size is larger on
      the server.
      
      If it is known that the remote size is larger than i_size, bump up the
      fetch size to that size.

      it again and the user may see the directory file size apparently change.

      Pull kvm updates from Paolo Bonzini:
       "s390:
      
         - More phys_to_virt conversions
      
         - Improvement of AP management for VSIE (nested virtualization)
      
        ARM64:
      
         - Numerous fixes for the pathological lock inversion issue that
           plagued KVM/arm64 since... forever.
      
         - New framework allowing SMCCC-compliant hypercalls to be forwarded
           to userspace, hopefully paving the way for some more features being
           moved to VMMs rather than be implemented in the kernel.
      
         - Large rework of the timer code to allow a VM-wide offset to be
           applied to both virtual and physical counters as well as a
           per-timer, per-vcpu offset that complements the global one. This
           last part allows the NV timer code to be implemented on top.
      
         - A small set of fixes to make sure that we don't change anything
           affecting the EL1&0 translation regime just after having having
           taken an exception to EL2 until we have executed a DSB. This
           ensures that speculative walks started in EL1&0 have completed.
      
         - The usual selftest fixes and improvements.
      
        x86:
      
         - Optimize CR0.WP toggling by avoiding an MMU reload when TDP is
           enabled, and by giving the guest control of CR0.WP when EPT is
           enabled on VMX (VMX-only because SVM doesn't support per-bit
           controls)
      
         - Add CR0/CR4 helpers to query single bits, and clean up related code
           where KVM was interpreting kvm_read_cr4_bits()'s "unsigned long"
           return as a bool
      
         - Move AMD_PSFD to cpufeatures.h and purge KVM's definition
      
         - Avoid unnecessary writes+flushes when the guest is only adding new
           PTEs
      
         - Overhaul .sync_page() and .invlpg() to utilize .sync_page()'s
           optimizations when emulating invalidations
      
         - Clean up the range-based flushing APIs
      
         - Revamp the TDP MMU's reaping of Accessed/Dirty bits to clear a
           single A/D bit using a LOCK AND instead of XCHG, and skip all of
           the "handle changed SPTE" overhead associated with writing the
           entire entry
      
         - Track the number of "tail" entries in a pte_list_desc to avoid
           having to walk (potentially) all descriptors during insertion and
           deletion, which gets quite expensive if the guest is spamming
           fork()
      
         - Disallow virtualizing legacy LBRs if architectural LBRs are
           available, the two are mutually exclusive in hardware
      
         - Disallow writes to immutable feature MSRs (notably
           PERF_CAPABILITIES) after KVM_RUN, similar to CPUID features
      
         - Overhaul the vmx_pmu_caps selftest to better validate
           PERF_CAPABILITIES
      
         - Apply PMU filters to emulated events and add test coverage to the
           pmu_event_filter selftest
      
         - AMD SVM:
             - Add support for virtual NMIs
             - Fixes for edge cases related to virtual interrupts
      
         - Intel AMX:
             - Don't advertise XTILE_CFG in KVM_GET_SUPPORTED_CPUID if
               XTILE_DATA is not being reported due to userspace not opting in
               via prctl()
             - Fix a bug in emulation of ENCLS in compatibility mode
             - Allow emulation of NOP and PAUSE for L2
             - AMX selftests improvements
             - Misc cleanups
      
        MIPS:
      
         - Constify MIPS's internal callbacks (a leftover from the hardware
           enabling rework that landed in 6.3)
      
        Generic:
      
         - Drop unnecessary casts from "void *" throughout kvm_main.c
      
         - Tweak the layout of "struct kvm_mmu_memory_cache" to shrink the
           struct size by 8 bytes on 64-bit kernels by utilizing a padding
           hole

       "DOE support is promoted from drivers/cxl/ to drivers/pci/ with Bjorn's
        blessing, and the CXL core continues to mature its media management
        capabilities with support for listing and injecting media errors. Some
        late fixes that missed v6.3-final are also included:
      
         - Refactor the DOE infrastructure (Data Object Exchange
           PCI-config-cycle mailbox) to be a facility of the PCI core rather
           than the CXL core.
      
           This is foundational for upcoming support for PCI
           device-attestation and PCIe / CXL link encryption.
      
         - Add support for retrieving and injecting poison for CXL memory
           expanders.
      
           This enabling uses trace-events to convey CXL media error records
           to user tooling. It includes translation of device-local addresses
           (DPA) to system physical addresses (SPA) and their corresponding
           CXL region.

       "More additions to the Rust core. Importantly, this adds the pin-init
        API, which will be used by other abstractions, such as the
        synchronization ones added here too:
      
         - pin-init API: a solution for the safe pinned initialization
           problem.
      
           This allows to reduce the need for 'unsafe' code in the kernel when
           dealing with data structures that require a stable address. Commit
           90e53c5e ("rust: add pin-init API core") contains a nice
           introduction -- here is an example of how it looks like:
      
              #[pin_data]
              struct Example {
                  #[pin]
                  value: Mutex<u32>,
      
                  #[pin]
                  value_changed: CondVar,
              }
      
              impl Example {
                  fn new() -> impl PinInit<Self> {
                      pin_init!(Self {
                          value <- new_mutex!(0),
                          value_changed <- new_condvar!(),
                      })
                  }
              }
      
              // In a `Box`.
              let b = Box::pin_init(Example::new())?;
      
              // In the stack.
              stack_pin_init!(let s = Example::new());
      
         - 'sync' module:
      
           New types 'LockClassKey' ('struct lock_class_key'), 'Lock',
           'Guard', 'Mutex' ('struct mutex'), 'SpinLock' ('spinlock_t'),
           'LockedBy' and 'CondVar' (uses 'wait_queue_head_t'), plus macros
           such as 'static_lock_class!' and 'new_spinlock!'.
      
           In particular, 'Lock' and 'Guard' are generic implementations that
           contain code that is common to all locks. Then, different backends
           (the new 'Backend' trait) are implemented and used to define types
           like 'Mutex':
      
              type Mutex<T> = Lock<T, MutexBackend>;
      
           In addition, new methods 'assume_init()', 'init_with()' and
           'pin_init_with()' for 'UniqueArc<MaybeUninit<T>>' and 'downcast()'
           for 'Arc<dyn Any + Send + Sync>'; as well as 'Debug' and 'Display'
           implementations for 'Arc' and 'UniqueArc'. Reduced stack usage of
           'UniqueArc::try_new_uninit()', too.
      
         - 'types' module:
      
           New trait 'AlwaysRefCounted' and new type 'ARef' (an owned
           reference to an always-reference-counted object, meant to be used
           in wrappers for C types that have their own ref counting
           functions).
      
           Moreover, new associated functions 'raw_get()' and 'ffi_init()' for
           'Opaque'.
      
         - New 'task' module with a new type 'Task' ('struct task_struct'),
           and a new macro 'current!' to safely get a reference to the current
           one.
      
         - New 'ioctl' module with new '_IOC*' const functions (equivalent to
           the C macros).
      
         - New 'uapi' crate, intended to be accessible by drivers directly.
      
         - 'macros' crate: new 'quote!' macro (similar to the one provided in
           userspace by the 'quote' crate); and the 'module!' macro now allows
           specifying multiple module aliases.
      
         - 'error' module:
      
           New associated functions for the 'Error' type, such as
           'from_errno()' and new functions such as 'to_result()'.
      
         - 'alloc' crate:
      
           More fallible 'Vec' methods: 'try_resize` and
           'try_extend_from_slice' and the infrastructure (imported from the
           Rust standard library) they need"

      Pull clk updates from Stephen Boyd:
       "Nothing looks out of the ordinary in this batch of clk driver updates.
      
        There are a couple patches to the core clk framework, but they're all
        basically cleanups or debugging aids. The driver updates and new
        additions are dominated in the diffstat by Qualcomm and MediaTek
        drivers. Qualcomm gained a handful of new drivers for various SoCs,
        and MediaTek gained a bunch of drivers for MT8188. The MediaTek
        drivers are being modernized as well, so there are updates all over
        that vendor's clk drivers. There's also a couple other new clk drivers
        in here, for example the Starfive JH7110 SoC support is added.
      
        Outside of the two major SoC vendors though, we have the usual
        collection of non-critical fixes and cleanups to various clk drivers.
        It's good to see that we're getting more cleanups and modernization
        patches. Maybe one day we'll be able to properly split clk providers
        from clk consumers.
      
        Core:
         - Print an informational message before disabling unused clks
      
        New Drivers:
         - BCM63268 timer clock and reset controller
         - Frequency Hopping (FHCTL) on MediaTek MT6795, MT8173, MT8192 and
           MT8195 SoCs
         - Mediatek MT8188 SoC clk drivers
         - Clock driver for Sunplus SP7021 SoC
         - Clk driver support for Loongson-2 SoCs
         - Clock driver for Skyworks Si521xx I2C PCIe clock generators
         - Initial Starfive JH7110 clk/reset support
         - Global clock controller drivers for Qualcomm SM7150, IPQ9574,
           MSM8917 and IPQ5332 SoCs
         - GPU clock controller drivers for SM6115, SM6125, SM6375 and SA8775P
           SoCs
      
        Updates:
         - Shrink size of clk_fractional_divider a little
         - Convert various clk drivers to devm_of_clk_add_hw_provider()
         - Convert platform clk drivers to remove_new()
         - Converted most Mediatek clock drivers to struct platform_driver
         - MediaTek clock drivers can be built as modules
         - Reimplement Loongson-1 clk driver with DT support

       "The big ticket item for this release is that support for RPC-with-TLS
        [RFC 9289] has been added to the Linux NFS server.
      
        The goal is to provide a simple-to-deploy, low-overhead in-transit
        confidentiality and peer authentication mechanism. It can supplement
        NFS Kerberos and it can protect the use of legacy non-cryptographic
        user authentication flavors such as AUTH_SYS. The TLS Record protocol
        is handled entirely by kTLS, meaning it can use either software
        encryption or offload encryption to smart NICs.
      
        Aside from that, work continues on improving NFSD's open file cache.
        Among the many clean-ups in that area is a patch to convert the
        rhashtable to use the list-hashing version of that data structure"

         - A trivial documentation fix in the timekeeping core
      
         - A really boring set of small fixes, enhancements and cleanups in
           the drivers code. No new clocksource/clockevent drivers for a
           change"
