| seccomp: add shmctl(), mlock(), and munlock() to the syscall whitelist |
| |
| 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 |
