      gcc-12: disable '-Wdangling-pointer' warning for now · 49beadbd
      Linus Torvalds authored
      While the concept of checking for dangling pointers to local variables
      at function exit is really interesting, the gcc-12 implementation is not
      compatible with reality, and results in false positives.
      
      For example, gcc sees us putting things on a local list head allocated
      on the stack, which involves exactly those kinds of pointers to the
      local stack entry:
      
        In function ‘__list_add’,
            inlined from ‘list_add_tail’ at include/linux/list.h:102:2,
            inlined from ‘rebuild_snap_realms’ at fs/ceph/snap.c:434:2:
        include/linux/list.h:74:19: warning: storing the address of local variable ‘realm_queue’ in ‘*&realm_27(D)->rebuild_item.prev’ [-Wdangling-pointer=]
           74 |         new->prev = prev;
              |         ~~~~~~~~~~^~~~~~
      
      But then gcc - understandably - doesn't really understand the big
      picture how the doubly linked list works, so doesn't see how we then end
      up emptying said list head in a loop and the pointer we added has been
      removed.
      
      Gcc also complains about us (intentionally) using this as a way to store
      a kind of fake stack trace, eg
      
        drivers/acpi/acpica/utdebug.c:40:38: warning: storing the address of local variable ‘current_sp’ in ‘acpi_gbl_entry_stack_pointer’ [-Wdangling-pointer=]
           40 |         acpi_gbl_entry_stack_pointer = &current_sp;
              |         ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~^~~~~~~~~~~~~
      
      which is entirely reasonable from a compiler standpoint, and we may want
      to change those kinds of patterns, but not not.
      
      So this is one of those "it would be lovely if the compiler were to
      complain about us leaving dangling pointers to the stack", but not this
      way.

      drm: imx: fix compiler warning with gcc-12 · 7aefd8b5
      Linus Torvalds authored
      Gcc-12 correctly warned about this code using a non-NULL pointer as a
      truth value:
      
        drivers/gpu/drm/imx/ipuv3-crtc.c: In function ‘ipu_crtc_disable_planes’:
        drivers/gpu/drm/imx/ipuv3-crtc.c:72:21: error: the comparison will always evaluate as ‘true’ for the address of ‘plane’ will never be NULL [-Werror=address]
           72 |                 if (&ipu_crtc->plane[1] && plane == &ipu_crtc->plane[1]->base)
              |                     ^
      
      due to the extraneous '&' address-of operator.
      
      Philipp Zabel points out that The mistake had no adverse effect since
      the following condition doesn't actually dereference the NULL pointer,
      but the intent of the code was obviously to check for it, not to take
      the address of the member.

      KEYS: trusted: tpm2: Fix migratable logic · dda53843
      David Safford authored
      When creating (sealing) a new trusted key, migratable
      trusted keys have the FIXED_TPM and FIXED_PARENT attributes
      set, and non-migratable keys don't. This is backwards, and
      also causes creation to fail when creating a migratable key
      under a migratable parent. (The TPM thinks you are trying to
      seal a non-migratable blob under a migratable parent.)
      
      The following simple patch fixes the logic, and has been
      tested for all four combinations of migratable and non-migratable
      trusted keys and parent storage keys. With this logic, you will
      get a proper failure if you try to create a non-migratable
      trusted key under a migratable parent storage key, and all other
      combinations work correctly.

      KVM: x86: do not report a vCPU as preempted outside instruction boundaries · 6cd88243
      Paolo Bonzini authored
      If a vCPU is outside guest mode and is scheduled out, it might be in the
      process of making a memory access.  A problem occurs if another vCPU uses
      the PV TLB flush feature during the period when the vCPU is scheduled
      out, and a virtual address has already been translated but has not yet
      been accessed, because this is equivalent to using a stale TLB entry.
      
      To avoid this, only report a vCPU as preempted if sure that the guest
      is at an instruction boundary.  A rescheduling request will be delivered
      to the host physical CPU as an external interrupt, so for simplicity
      consider any vmexit *not* instruction boundary except for external
      interrupts.
      
      It would in principle be okay to report the vCPU as preempted also
      if it is sleeping in kvm_vcpu_block(): a TLB flush IPI will incur the
      vmentry/vmexit overhead unnecessarily, and optimistic spinning is
      also unlikely to succeed.  However, leave it for later because right
      now kvm_vcpu_check_block() is doing memory accesses.  Even
      though the TLB flush issue only applies to virtual memory address,
      it's very much preferrable to be conservative.

      Paolo Bonzini authored
      Similar to the Xen path, only change the vCPU's reported state if the vCPU
      was actually preempted.  The reason for KVM's behavior is that for example
      optimistic spinning might not be a good idea if the guest is doing repeated
      exits to userspace; however, it is confusing and unlikely to make a difference,
      because well-tuned guests will hardly ever exit KVM_RUN in the first place.

      bluetooth: don't use bitmaps for random flag accesses · e1cff700
      Linus Torvalds authored
      The bluetooth code uses our bitmap infrastructure for the two bits (!)
      of connection setup flags, and in the process causes odd problems when
      it converts between a bitmap and just the regular values of said bits.
      
      It's completely pointless to do things like bitmap_to_arr32() to convert
      a bitmap into a u32.  It shoudln't have been a bitmap in the first
      place.  The reason to use bitmaps is if you have arbitrary number of
      bits you want to manage (not two!), or if you rely on the atomicity
      guarantees of the bitmap setting and clearing.
      
      The code could use an "atomic_t" and use "atomic_or/andnot()" to set and
      clear the bit values, but considering that it then copies the bitmaps
      around with "bitmap_to_arr32()" and friends, there clearly cannot be a
      lot of atomicity requirements.
      
      So just use a regular integer.
      
      In the process, this avoids the warnings about erroneous use of
      bitmap_from_u64() which were triggered on 32-bit architectures when
      conversion from a u64 would access two words (and, surprise, surprise,
      only one word is needed - and indeed overkill - for a 2-bit bitmap).
      
      That was always problematic, but the compiler seems to notice it and
      warn about the invalid pattern only after commit 0a97953f ("lib: add
      bitmap_{from,to}_arr64") changed the exact implementation details of
      'bitmap_from_u64()', as reported by Sudip Mukherjee and Stephen Rothwell.

      Pull hardware timestamping subsystem from Thierry Reding:
       "This contains the new HTE (hardware timestamping engine) subsystem
        that has been in the works for a couple of months now.
      
        The infrastructure provided allows for drivers to register as hardware
        timestamp providers, while consumers will be able to request events
        that they are interested in (such as GPIOs and IRQs) to be timestamped
        by the hardware providers.
      
        Note that this currently supports only one provider, but there seems
        to be enough interest in this functionality and we expect to see more
        drivers added once this is merged"

        platforms as another future timestamp provider ]
