  "message": "[DFSan] Fix recvmsg wrapper to support MSG_TRUNC flag. (#92599)\n\nThe MSG_TRUNC flag makes recvmsg return the real length of the packet,\r\neven if it was too big to fit in the provided buffer. This is commonly\r\nused together with MSG_PEEK.\r\n\r\nWithout this patch, dfsan\u0027s clear_msghdr_labels expects the return value\r\nof recvmsg (size recieved) to be less than or equal to the iov buffer\r\nlength where recvmsg writes data, resulting in a crash.",
