This driver can handle read and write requests, + * but it doesn't know anything about the special restrictions that apply to + * packet writing. One restriction is that write requests must be aligned to + * packet boundaries on the physical media, and the size of a write request + * must be equal to the packet size. Another restriction is that a + * GPCMD_FLUSH_CACHE command has to be issued to the drive before a read + * command, if the previous command was a write. + * + * The purpose of the packet writing driver is to hide these restrictions from + * higher layers, such as file systems, and present a block device that can be + * randomly read and written using 2kB-sized blocks. + * + * The lowest layer in the packet writing driver is the packet I/O scheduler. + * Its data is defined by the struct packet_iosched and includes two bio + * queues with pending read and write requests. These queues are processed + * by the pkt_iosched_process_queue() function. The write requests in this + * queue are already properly aligned and sized. This layer is responsible for + * issuing the flush cache commands and scheduling the I/O in a good order. + * + * The next layer transforms unaligned write requests to aligned writes. This + * transformation requires reading missing pieces of data from the underlying + * block device, assembling the pieces to full packets and queuing them to the + * packet I/O scheduler. + * + * At the top layer there is a custom ->submit_bio function that forwards + * read requests directly to the iosched queue and puts write requests in the + * unaligned write queue. A kernel thread performs the necessary read + * gathering to convert the unaligned writes to aligned writes and then feeds + * them to the packet I/O scheduler. + * + *************************************************************************/ + +#define pr_fmt(fmt) KBUILD_MODNAME ": " fmt + +#include <linux/pktcdvd.h> +#include <linux/module.h> +#include <linux/types.h> +#include <linux/kernel.h> +#include <linux/compat.h> +#include <linux/kthread.h> +#include <linux/errno.h> +#include <linux/spinlock.h> +#include <linux/file.h> +#include <linux/proc_fs.h> +#include <linux/seq_file.h> +#include <linux/miscdevice.h> +#include <linux/freezer.h> +#include <linux/mutex.h> +#include <linux/slab.h> +#include <linux/backing-dev.h> +#include <scsi/scsi_cmnd.h> +#include <scsi/scsi_ioctl.h> +#include <scsi/scsi.h> +#include <linux/debugfs.h> +#include <linux/device.h> +#include <linux/nospec.h> +#include <linux/uaccess.h> + +#define DRIVER_NAME "pktcdvd" + +#define pkt_err(pd, fmt, ...) \ + pr_err("%s: " fmt, pd->name, ##__VA_ARGS__) +#define pkt_notice(pd, fmt, ...) \ + pr_notice("%s: " fmt, pd->name, ##__VA_ARGS__) +#define pkt_info(pd, fmt, ...) \ + pr_info("%s: " fmt, pd->name, ##__VA_ARGS__) + +#define pkt_dbg(level, pd, fmt, ...) \ +do { \ + if (level == 2 && PACKET_DEBUG >= 2) \ + pr_notice("%s: %s():" fmt, \ + pd->name, __func__, ##__VA_ARGS__);
