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 Signed-off-by: Paul Moore --- qemu-seccomp.c | 5 ++++- 1 file changed, 4 insertions(+), 1 deletion(-) diff --git a/qemu-seccomp.c b/qemu-seccomp.c index caa926e..3db1e9b 100644 --- a/qemu-seccomp.c +++ b/qemu-seccomp.c @@ -225,7 +225,10 @@ static const struct QemuSeccompSyscall seccomp_whitelist[] = { { SCMP_SYS(fchmod), 240 }, { SCMP_SYS(shmget), 240 }, { SCMP_SYS(shmat), 240 }, - { SCMP_SYS(shmdt), 240 } + { SCMP_SYS(shmdt), 240 }, + { SCMP_SYS(shmctl), 240 }, + { SCMP_SYS(mlock), 240 }, + { SCMP_SYS(munlock), 240 } }; int seccomp_start(void)
