Okay, so I'm trying to classify this bug report for QEMU. Let me read through it carefully. The user is reporting that when sending multiple control messages over a Unix socket in QEMU, only the first one is received. They mention using a test program with SCM_CREDENTIALS and SCM_RIGHTS. On native systems, both are received, but not in QEMU. They traced this to a glibc bug, specifically related to uninitialized buffers causing CMSG_NXTHDR to return NULL incorrectly. The issue arises because QEMU's `target_to_host_cmsg` stops encoding as soon as either buffer ends, which leads to losing target messages if the host buffer runs out first. They suggest adding an assertion and provided a patch that zeros the buffer. Looking at the categories: device, graphic, socket, network... This seems related to socket operations because it's about sending control messages over Unix sockets. The problem occurs during communication via sockets within QEMU. So the category would be 'socket'. socket
