[Qemu-devel] [PULL 02/02] seccomp: add shmctl(), mlock(), and munlock() to the syscall whitelist

[Eduardo Otubo <otubo@linux.vnet.ibm.com>]

From: Paul Moore <pmoore@redhat.com>

Additional testing reveals that PulseAudio requires shmctl() and the
mlock()/munlock() syscalls on some systems/configurations.  As before,
on systems that do require these syscalls, the problem can be seen with
the following command line:

  # qemu -monitor stdio  -sandbox on \
         -device intel-hda -device hda-duplex
