      parisc: Report SIGSEGV instead of SIGBUS when running out of stack · 24746231
      Helge Deller authored
      
      
      When a process runs out of stack the parisc kernel wrongly faults with SIGBUS
      instead of the expected SIGSEGV signal.
      
      This example shows how the kernel faults:
      do_page_fault() command='a.out' type=15 address=0xfaac2000 in libc-2.24.so[f8308000+16c000]
      trap #15: Data TLB miss fault, vm_start = 0xfa2c2000, vm_end = 0xfaac2000
      
      The vma->vm_end value is the first address which does not belong to the vma, so
      adjust the check to include vma->vm_end to the range for which to send the
      SIGSEGV signal.
      
      This patch unbreaks building the debian libsigsegv package.

      Architectures with a compat syscall table must put compat_sys_keyctl()
      in it, not sys_keyctl().  The parisc architecture was not doing this;
      fix it.

      parisc: Add Page Deallocation Table (PDT) support · c9c2877d
      Helge Deller authored
      
      
      The firmare in most parisc machines maintains a Page Deallocation Table (PDT)
      which holds a list of physical memory addresses where hardware detected memory
      errors (single bit and double bit errors).
      
      This patch adds the missing PDC firmware calls and the logic to read the PDT
      from firmware, report all current PDT entries and exclude the reported bad
      memory from being used by Linux.

      sparc64: fix fault handling in NGbzero.S and GENbzero.S · 3c7f6221
      Dave Aldridge authored
      
      
      When any of the functions contained in NGbzero.S and GENbzero.S
      vector through *bzero_from_clear_user, we may end up taking a
      fault when executing one of the store alternate address space
      instructions. If this happens, the exception handler does not
      restore the %asi register.
      
      This commit fixes the issue by introducing a new exception
      handler that ensures the %asi register is restored when
      a fault is handled.

        arm/ and arm64/ as include prefixes. This will avoid other local hacks

      proc: try to remove use of FOLL_FORCE entirely · 8ee74a91
      Linus Torvalds authored
      
      
      We fixed the bugs in it, but it's still an ugly interface, so let's see
      if anybody actually depends on it.  It's entirely possible that nothing
      actually requires the whole "punch through read-only mappings"
      semantics.
      
      For example, gdb definitely uses the /proc/<pid>/mem interface, but it
      looks like it mainly does it for regular reads of the target (that don't
      need FOLL_FORCE), and looking at the gdb source code seems to fall back
      on the traditional ptrace(PTRACE_POKEDATA) interface if it needs to.
      
      If this breaks something, I do have a (more complex) version that only
      enables FOLL_FORCE when somebody has PTRACE_ATTACH'ed to the target,
      like the comment here used to say ("Maybe we should limit FOLL_FORCE to
      actual ptrace users?").

      rtnl_xdp_fill() returning an error code.
      
      To resolve this, introduce a subset of the NDOs meant for the VF
      in a seperate structure and register that one instead for VFs,
      and omit the ndo_xdp initialization.

      qed: Correct doorbell configuration for !4Kb pages · a82dadbc
      Ram Amrani authored
      When configuring the doorbell DPI address, driver aligns the start
      address to 4KB [HW-pages] instead of host PAGE_SIZE.
      As a result, RoCE applications might receive addresses which are
      unaligned to pages [when PAGE_SIZE > 4KB], which is a security risk.

      qed: Tell QM the number of tasks · c9f0523b
      Mintz, Yuval authored
      
      
      Driver doesn't pass the number of tasks to the QM init logic
      which would cause back-pressure in scenarios requiring many tasks
      [E.g., using max MRs] and thus reduced performance.

      net/mlx4_core: Reduce harmless SRIOV error message to debug level · 83bd5118
      Jack Morgenstein authored
      Under SRIOV resource management, extra counters are allocated to VFs
      from a free pool. If that pool is empty, the ALLOC_RES command for
      a counter resource fails -- and this generates a misleading error
      message in the message log.
      
      Under SRIOV, each VF is allocated (i.e., guaranteed) 2 counters --
      one counter per port. For ETH ports, the RoCE driver requests an
      additional counter (above the guaranteed counters). If that request
      fails, the VF RoCE driver simply uses the default (i.e., guaranteed)
      counter for that port.
      
      Thus, failing to allocate an additional counter does not constitute
      a  problem, and the error message on the PF when this occurs should
      be reduced to debug level.
      
      Finally, to identify the situation that the reason for the failure is
      that no resources are available to grant to the VF, we modified the
      error returned by mlx4_grant_resource to -EDQUOT (Quota exceeded),
      which more accurately describes the error.
