pktcdvd: remove queue_lock around blk_queue_max_hw_sectors

2018-11-16T16:16:59Z

blk_queue_max_hw_sectors can't do anything with queue_lock protection so don't hold it. Reviewed-by: Omar Sandoval Signed-off-by: Christoph Hellwig Signed-off-by: Jens Axboe

block: remove the queue_lock indirection

2018-11-15T19:17:28Z

With the legacy request path gone there is no good reason to keep queue_lock as a pointer, we can always use the embedded lock now. Reviewed-by: Hannes Reinecke Signed-off-by: Christoph Hellwig Fixed floppy and blk-cgroup missing conversions and half done edits. Signed-off-by: Jens Axboe

pktcdvd: fix fall-through annotation

2018-10-02T14:36:58Z

Replace "fallthru" with a proper "fall through" annotation. This fix is part of the ongoing efforts to enabling -Wimplicit-fallthrough Signed-off-by: Gustavo A. R. Silva Signed-off-by: Jens Axboe

pktcdvd: fix setting of 'ret' error return for a few cases

2018-08-16T20:09:28Z

We initialize it to -ENOMEM, but then later overwrite it. After overwriting, we don't set it again for two later failure cases. Reported-by: Jason Wood Signed-off-by: Jens Axboe

block: Switch struct packet_command to use struct scsi_sense_hdr

2018-08-02T21:22:13Z

There is a lot of needless struct request_sense usage in the CDROM code. These can all be struct scsi_sense_hdr instead, to avoid any confusion over their respective structure sizes. This patch is a lot of noise changing "sense" to "sshdr", but the final code is more readable to distinguish between "sense" meaning "struct request_sense" and "sshdr" meaning "struct scsi_sense_hdr".

pktcdvd: Fix possible Spectre-v1 for pkt_devs

2018-07-28T15:08:42Z

User controls @dev_minor which to be used as index of pkt_devs. So, It can be exploited via Spectre-like attack. (speculative execution) This kind of attack leaks address of pkt_devs, [1] It leads an attacker to bypass security mechanism such as KASLR. So sanitize @dev_minor before using it to prevent attack.
