Minor differences from upstream patch due to a slowly diverging

9ae3a8 |
codebase.

seccomp: add shmctl(), mlock(), and munlock() to the syscall whitelist
|
|
|
9ae3a8 |
|
|
|
9ae3a8 |
Additional testing reveals that PulseAudio requires shmctl() and the
|
|
|
9ae3a8 |
mlock()/munlock() syscalls on some systems/configurations. As before,
|
|
|
9ae3a8 |
on systems that do require these syscalls, the problem can be seen with
|
|
|
9ae3a8 |
the following command line:
|
|
|
9ae3a8 |
|
|
|
9ae3a8 |
# qemu -monitor stdio -sandbox on \
|
|
|
9ae3a8 |
-device intel-hda -device hda-duplex
