      arm64: don't kill the kernel on a bad esr from el0 · 9955ac47
      Mark Rutland 提交于
      Rather than completely killing the kernel if we receive an esr value we
      can't deal with in the el0 handlers, send the process a SIGILL and log
      the esr value in the hope that we can debug it. If we receive a bad esr
      from el1, we'll die() as before.

      arm64: treat unhandled compat el0 traps as undef · 381cc2b9
      Mark Rutland 提交于
      Currently, if a compat process reads or writes from/to a disabled
      cp15/cp14 register, the trap is not handled by the el0_sync_compat
      handler, and the kernel will head to bad_mode, where it will die(), and
      oops(). For 64 bit processes, disabled system register accesses are
      currently treated as unhandled instructions.
      
      This patch modifies entry.S to treat these unhandled traps as undefined
      instructions, sending a SIGILL to userspace. This gives processes a
      chance to handle this and stop using inaccessible registers, and
      prevents further issues in the kernel as a result of the die().

      x86: Allow FPU to be used at interrupt time even with eagerfpu · 5187b28f
      Pekka Riikonen 提交于
      With the addition of eagerfpu the irq_fpu_usable() now returns false
      negatives especially in the case of ksoftirqd and interrupted idle task,
      two common cases for FPU use for example in networking/crypto.  With
      eagerfpu=off FPU use is possible in those contexts.  This is because of
      the eagerfpu check in interrupted_kernel_fpu_idle():
      
      ...
        * For now, with eagerfpu we will return interrupted kernel FPU
        * state as not-idle. TBD: Ideally we can change the return value
        * to something like __thread_has_fpu(current). But we need to
        * be careful of doing __thread_clear_has_fpu() before saving
        * the FPU etc for supporting nested uses etc. For now, take
        * the simple route!
      ...
       	if (use_eager_fpu())
       		return 0;
      
      As eagerfpu is automatically "on" on those CPUs that also have the
      features like AES-NI this patch changes the eagerfpu check to return 1 in
      case the kernel_fpu_begin() has not been said yet.  Once it has been the
      __thread_has_fpu() will start returning 0.
      
      Notice that with eagerfpu the __thread_has_fpu is always true initially.
      FPU use is thus always possible no matter what task is under us, unless
      the state has already been saved with kernel_fpu_begin().
      
      [ hpa: this is a performance regression, not a correctness regression,
        but since it can be quite serious on CPUs which need encryption at
        interrupt time I am marking this for urgent/stable. ]

      x86, crc32-pclmul: Fix build with older binutils · 2baad612
      Jan Beulich 提交于
      binutils prior to 2.18 (e.g. the ones found on SLE10) don't support
      assembling PEXTRD, so a macro based approach like the one for PCLMULQDQ
      in the same file should be used.
      
      This requires making the helper macros capable of recognizing 32-bit
      general purpose register operands.

      aerdrv: Move cper_print_aer() call out of interrupt context · 37448adf
      Lance Ortiz 提交于
      The following warning was seen on 3.9 when a corrected PCIe error was being
      handled by the AER subsystem.
      
      WARNING: at .../drivers/pci/search.c:214 pci_get_dev_by_id+0x8a/0x90()
      
      This occurred because a call to pci_get_domain_bus_and_slot() was added to
      cper_print_pcie() to setup for the call to cper_print_aer().  The warning
      showed up because cper_print_pcie() is called in an interrupt context and
      pci_get* functions are not supposed to be called in that context.
      
      The solution is to move the cper_print_aer() call out of the interrupt
      context and into aer_recover_work_func() to avoid any warnings when calling
      pci_get* functions.
