      x86/mm: Make in_compat_syscall() work during exec · ada26481
      Dmitry Safonov authored
      The x86 mmap() code selects the mmap base for an allocation depending on
      the bitness of the syscall. For 64bit sycalls it select mm->mmap_base and
      for 32bit mm->mmap_compat_base.
      
      On execve the registers of the task invoking exec() are copied to the child
      pt_regs. So child->pt_regs->orig_ax contains the execve syscall number of the
      parent.
      
      exec() calls mmap() which in turn uses in_compat_syscall() to check whether
      the mapping is for a 32bit or a 64bit task. The decision is made on the
      following criteria:
      
        ia32	  child->thread.status & TS_COMPAT
         x32	  child->pt_regs.orig_ax & __X32_SYSCALL_BIT
        ia64	  !ia32 && !x32 
      
      child->thread.status is corretly set up in set_personality_*(), but the
      syscall number in child->pt_regs.orig_ax is left unmodified.
      
      Therefore the parent/child combinations work or fail in the following way:
      
      Parent Child Child->thread_status  child->pt_regs.orig_ax  in_compat()  Works
      ia64    ia64   TS_COMPAT == 0	   __X32_SYSCALL_BIT == 0     false       Y
      ia64    ia32   TS_COMPAT == 1	   __X32_SYSCALL_BIT == 0     true        Y
      ia64     x32   TS_COMPAT == 0	   __X32_SYSCALL_BIT == 0     false       N
      ia32    ia64   TS_COMPAT == 0	   __X32_SYSCALL_BIT == 0     false       Y
      ia32    ia32   TS_COMPAT == 1	   __X32_SYSCALL_BIT == 0     true        Y
      ia32     x32   TS_COMPAT == 0	   __X32_SYSCALL_BIT == 0     false       N
       x32    ia64   TS_COMPAT == 0	   __X32_SYSCALL_BIT == 1     true        N
       x32    ia32   TS_COMPAT == 1	   __X32_SYSCALL_BIT == 1     true        Y
       x32     x32   TS_COMPAT == 0	   __X32_SYSCALL_BIT == 1     true        Y
      
      Make set_personality_*() store the syscall number incl. __X32_SYSCALL_BIT
      which corresponds to the newly started ELF executable in the childs
      pt_regs, i.e. pretend that the exec was invoked from a task with the same
      executable format.
      
      So both thread.status and pt_regs.orig_ax correspond to the new ELF format
      and in_compat_syscall() returns the correct result.

      x86/boot/32: Flip the logic in test_wp_bit() · 952a6c2c
      Borislav Petkov authored
      ... to have a natural "likely()" in the code flow and thus have the
      success case with a branch 99.999% of the times non-taken and function
      return code following it instead of jumping to it each time.
      
      This puts the panic() call at the end of the function - it is going to
      be practically unreachable anyway.
      
      The C code is a bit more readable too.
      
      No functionality change.

      x86/arch_prctl: Add ARCH_[GET|SET]_CPUID · e9ea1e7f
      Kyle Huey authored
      Intel supports faulting on the CPUID instruction beginning with Ivy Bridge.
      When enabled, the processor will fault on attempts to execute the CPUID
      instruction with CPL>0. Exposing this feature to userspace will allow a
      ptracer to trap and emulate the CPUID instruction.
      
      When supported, this feature is controlled by toggling bit 0 of
      MSR_MISC_FEATURES_ENABLES. It is documented in detail in Section 2.3.2 of
      https://bugzilla.kernel.org/attachment.cgi?id=243991
      
      Implement a new pair of arch_prctls, available on both x86-32 and x86-64.
      
      ARCH_GET_CPUID: Returns the current CPUID state, either 0 if CPUID faulting
          is enabled (and thus the CPUID instruction is not available) or 1 if
          CPUID faulting is not enabled.
      
      ARCH_SET_CPUID: Set the CPUID state to the second argument. If
          cpuid_enabled is 0 CPUID faulting will be activated, otherwise it will
          be deactivated. Returns ENODEV if CPUID faulting is not supported on
          this system.
      
      The state of the CPUID faulting flag is propagated across forks, but reset
      upon exec.

      x86/syscalls/32: Wire up arch_prctl on x86-32 · 79170fda

      Hook up arch_prctl to call do_arch_prctl() on x86-32, and in 32 bit compat
      mode on x86-64. This allows to have arch_prctls that are not specific to 64

      On UML, simply stub out this syscall.

      x86/tls: Forcibly set the accessed bit in TLS segments · 5b781c7e
      Andy Lutomirski authored
      For mysterious historical reasons, struct user_desc doesn't indicate
      whether segments are accessed.  set_thread_area() has always programmed
      segments as non-accessed, so the first write will set the accessed bit.
      This will fault if the GDT is read-only.
      
      Fix it by making TLS segments start out accessed.
      
      If this ends up breaking something, we could, in principle, leave TLS
      segments non-accessed and fix them up when we get the page fault.  I'd be
      surprised, though -- AFAIK all the nasty legacy segmented programs (DOSEMU,
      Wine, things that run on DOSEMU and Wine, etc.) do their nasty segmented
      things using the LDT and not the GDT.  I assume this is mainly because old
      OSes (Linux and otherwise) didn't historically provide APIs to do nasty
      things in the GDT.
      
      Fixes: 45fc8757 ("x86: Make the GDT remapping read-only on 64-bit")
