      target/i386: Add SGX aex-notify and EDECCSSA support
      
      The new SGX Asynchronous Exit (AEX) notification mechanism (AEX-notify)
      allows one enclave to receive a notification in the ERESUME after the
      enclave exit due to an AEX.  EDECCSSA is a new SGX user leaf function
      (ENCLU[EDECCSSA]) to facilitate the AEX notification handling.
      
      Whether the hardware supports to create enclave with AEX-notify support
      is enumerated via CPUID.(EAX=0x12,ECX=0x1):EAX[10].  The new EDECCSSA
      user leaf function is enumerated via CPUID.(EAX=0x12,ECX=0x0):EAX[11].
      
      Add support to allow to expose the new SGX AEX-notify feature and the
      new EDECCSSA user leaf function to KVM guest.

      meson: accept relative symlinks in "meson introspect --installed" data
      
      When installing shared libraries, as is the case for libvfio-user.so,
      Meson will include relative symbolic links in the output of
      "meson introspect --installed":
      
        {
          "libvfio-user.so": "/usr/local/lib64/libvfio-user.so",
          ...
        }
      
      In the case of scripts/symlink-install-tree.py, this will
      be a symbolic link to a symbolic link but, in any case, there is
      no issue in creating it.

      meson: support meson 0.64 -Doptimization=plain
      
      In Meson 0.64, the optimization built-in option now accepts the "plain" 
value,
      which will not set any optimization flags.  While QEMU does not check the
      contents of the option and therefore does not suffer any ill effect
      from the new value, it uses get_option to print the optimization flags
      in the summary.  Clean the code up to remove duplication, and check for
      -Doptimization=plain at the same time.

      Some warnings are hardcoded in QEMU_CFLAGS and not tested.  There is
      no particular reason to single out these five, as many more -W flags are
      present on all the supported compilers.  For homogeneity when moving
      the detection to meson, make them use the same warn_flags infrastructure.

      meson: tweak hardening options for Windows
      
      meson.build has been enabling ASLR _only_ for debug builds since
      commit d2147e04f95f ("configure: move Windows flags detection to meson",
      2022-05-07); instead it was supposed to disable it for debug builds.
      
      However, the flag has been enabled for DLLs upstream for roughly 2
      years (https://sourceware.org/bugzilla/show_bug.cgi?id=19011), and
      also by some distros including Debian for 6 years even
      (https://bugs.debian.org/cgi-bin/bugreport.cgi?bug=836365).
      
      Enable it unconditionally; we can fix the reversed logic of commit
      d2147e04f95f later if there are any reports, but for now just
      enable the hardening.
      
      Also add -Wl,--high-entropy-va, which also controls ASLR.

  Author: Greg Kurz <groug@xxxxxxxx>
  Date:   Tue Nov 8 15:00:32 2022 +0100
  
      util/log: Always send errors to logfile when daemonized
      
      When QEMU is started with `-daemonize`, all stdio descriptors get
      redirected to `/dev/null`. This basically means that anything
      printed with error_report() and friends is lost.
      
      Current logging code allows to redirect to a file with `-D` but
      this requires to enable some logging item with `-d` as well to
      be functional.
      
      Relax the check on the log flags when QEMU is daemonized, so that
      other users of stderr can benefit from the redirection, without the
      need to enable unwanted debug logs. Previous behaviour is retained
      for the non-daemonized case. The logic is unrolled as an `if` for
      better readability. The qemu_log_level and log_per_thread globals
      reflect the state we want to transition to at this point : use
      them instead of the intermediary locals for correctness.
      
      qemu_set_log_internal() is adapted to open a per-thread log file
      when '-d tid' is passed. This is done by hijacking qemu_try_lock()
      which seems simpler that refactoring the code.

  Author: Paolo Bonzini <pbonzini@xxxxxxxxxx>
  Date:   Tue Nov 8 15:00:31 2022 +0100
  
      util/log: do not close and reopen log files when flags are turned off
      
      log_append makes sure that if you turn off the logging (which clears
      log_flags and makes need_to_open_file false) the old log is not
      overwritten.  The usecase is that if you remove or move the file
      QEMU will not keep writing to the old file.  However, this is
      not always the desited behavior, in particular having log_append==1
      after changing the file name makes little sense.
      
      When qemu_set_log_internal is called from the logfile monitor
      command, filename must be non-NULL and therefore changed_name must
      be true.  Therefore, the only case where the file is closed and
      need_to_open_file == false is indeed when log_flags becomes
      zero.  In this case, just flush the file and do not bother
      closing it, thus faking the same append behavior as previously.
      
      The behavioral change is that changing the logfile twice, for
      example log1 -> log2 -> log1, will cause log1 to be overwritten.
      This can simply be documented, since it is not a particularly
      surprising behavior.

      target/i386: Add SGX aex-notify and EDECCSSA support
      
      The new SGX Asynchronous Exit (AEX) notification mechanism (AEX-notify)
      allows one enclave to receive a notification in the ERESUME after the
      enclave exit due to an AEX.  EDECCSSA is a new SGX user leaf function
      (ENCLU[EDECCSSA]) to facilitate the AEX notification handling.
      
      Whether the hardware supports to create enclave with AEX-notify support
      is enumerated via CPUID.(EAX=0x12,ECX=0x1):EAX[10].  The new EDECCSSA
      user leaf function is enumerated via CPUID.(EAX=0x12,ECX=0x0):EAX[11].
      
      Add support to allow to expose the new SGX AEX-notify feature and the
      new EDECCSSA user leaf function to KVM guest.

      meson: accept relative symlinks in "meson introspect --installed" data
      
      When installing shared libraries, as is the case for libvfio-user.so,
      Meson will include relative symbolic links in the output of
      "meson introspect --installed":
      
        {
          "libvfio-user.so": "/usr/local/lib64/libvfio-user.so",
          ...
        }
      
      In the case of scripts/symlink-install-tree.py, this will
      be a symbolic link to a symbolic link but, in any case, there is
      no issue in creating it.

      meson: support meson 0.64 -Doptimization=plain
      
      In Meson 0.64, the optimization built-in option now accepts the "plain" 
value,
      which will not set any optimization flags.  While QEMU does not check the
      contents of the option and therefore does not suffer any ill effect
      from the new value, it uses get_option to print the optimization flags
      in the summary.  Clean the code up to remove duplication, and check for
      -Doptimization=plain at the same time.

      configure: test all warnings
      
      Some warnings are hardcoded in QEMU_CFLAGS and not tested.  There is
      no particular reason to single out these five, as many more -W flags are
      present on all the supported compilers.  For homogeneity when moving
      the detection to meson, make them use the same warn_flags infrastructure.

      commit d2147e04f95f ("configure: move Windows flags detection to meson",
      2022-05-07); instead it was supposed to disable it for debug builds.
      
      However, the flag has been enabled for DLLs upstream for roughly 2
      years (https://sourceware.org/bugzilla/show_bug.cgi?id=19011), and
      also by some distros including Debian for 6 years even
      (https://bugs.debian.org/cgi-bin/bugreport.cgi?bug=836365).
      
      Enable it unconditionally; we can fix the reversed logic of commit
      d2147e04f95f later if there are any reports, but for now just
      enable the hardening.
      
      Also add -Wl,--high-entropy-va, which also controls ASLR.

      Ensure that qemu-ga variables set at configure time are kept
      later when the script is rerun.  For preserve_env to work,
      the variables need to be empty so move the default values
      to config-host.mak generation.

      configure: cleanup $cpu tests
      
      $cpu is derived from preprocessor defines rather than uname these days,
      so do not bother using isainfo on Solaris.  Likewise do not recognize
      BeOS's uname -m output.
      
      Keep the other, less OS-specific canonicalizations for the benefit
      of people using --cpu.

      util/log: Always send errors to logfile when daemonized
      
      When QEMU is started with `-daemonize`, all stdio descriptors get
      redirected to `/dev/null`. This basically means that anything
      printed with error_report() and friends is lost.
      
      Current logging code allows to redirect to a file with `-D` but
      this requires to enable some logging item with `-d` as well to
      be functional.
      
      Relax the check on the log flags when QEMU is daemonized, so that
      other users of stderr can benefit from the redirection, without the
      need to enable unwanted debug logs. Previous behaviour is retained
      for the non-daemonized case. The logic is unrolled as an `if` for
      better readability. The qemu_log_level and log_per_thread globals
      reflect the state we want to transition to at this point : use
      them instead of the intermediary locals for correctness.
      
      qemu_set_log_internal() is adapted to open a per-thread log file
      when '-d tid' is passed. This is done by hijacking qemu_try_lock()
      which seems simpler that refactoring the code.

      util/log: do not close and reopen log files when flags are turned off
      
      log_append makes sure that if you turn off the logging (which clears
      log_flags and makes need_to_open_file false) the old log is not
      overwritten.  The usecase is that if you remove or move the file
      QEMU will not keep writing to the old file.  However, this is
      not always the desited behavior, in particular having log_append==1
      after changing the file name makes little sense.
      
      When qemu_set_log_internal is called from the logfile monitor
      command, filename must be non-NULL and therefore changed_name must
      be true.  Therefore, the only case where the file is closed and
      need_to_open_file == false is indeed when log_flags becomes
      zero.  In this case, just flush the file and do not bother
      closing it, thus faking the same append behavior as previously.
      
      The behavioral change is that changing the logfile twice, for
      example log1 -> log2 -> log1, will cause log1 to be overwritten.
      This can simply be documented, since it is not a particularly
      surprising behavior.
