Subject: [Qemu-devel] [PATCH] seccomp: add semctl() to the syscall whitelist
Date: Thu, 14 Aug 2014 13:19:32 -0400 [thread overview]
Message-ID: <20140814171932.5016.27390.stgit@localhost> (raw)
QEMU needs to call semctl() for correct operation. This particular
problem was identified on shutdown with the following commandline:
# qemu -sandbox on -monitor stdio \
-device intel-hda -device hda-duplex -vnc :0
