block: genhd: remove async_events field

2019-04-12T19:35:22+00:00

The async_events field, intended to be used for drivers that support asynchronous notifications about disk events (aka media change events), isn't currently used by any driver, and apparently that has been that way for a long time (if not forever). Remove it. Reviewed-by: Hannes Reinecke Reviewed-by: Christoph Hellwig Signed-off-by: Martin Wilck Signed-off-by: Jens Axboe

pktcdvd: remove queue_lock around blk_queue_max_hw_sectors

2018-11-16T16:16:59+00:00

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

2018-11-15T19:17:28+00:00

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

2018-10-02T14:36:58+00:00

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

2018-08-16T20:09:28+00:00

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

2018-08-02T21:22:13+00:00

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

2018-07-28T15:08:42+00:00

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.
