Stefan, the issue you mentioned has been fixed.
Almost all patches have been reviewed, thank you very much
to Stefan and Klaus.
v7->v8:
- Fix num_keys may be less than 0 at scsi_pr_read_keys_complete().
- Fix buf memory leak at iscsi driver.
v6->v7:
- Add buferlen size check at SCSI layer.
- Add pr_cap calculation in bdrv_merge_limits() function at block layer,
so the ugly bs->file->bs->bl.pr_cap in scsi and nvme layers was
changed to bs->bl.pr_cap.
- Fix memory leak at iscsi driver, and some other spelling errors.
v5->v6:
- Add relevant comments in the io layer.
v4->v5:
- Fixed a memory leak bug at hw/nvme/ctrl.c.
v3->v4:
- At the nvme layer, the two patches of enabling the ONCS
function and enabling rescap are combined into one.
- At the nvme layer, add helper functions for pr capacity
conversion between the block layer and the nvme layer.
v2->v3:
In v2 Persist Through Power Loss(PTPL) is enable default.
In v3 PTPL is supported, which is passed as a parameter.
v1->v2:
- Add sg_persist --report-capabilities for SCSI protocol and enable
oncs and rescap for NVMe protocol.
- Add persistent reservation capabilities constants and helper functions for
SCSI and NVMe protocol.
- Add comments for necessary APIs.
v1:
- Add seven APIs about persistent reservation command for block layer.
These APIs including reading keys, reading reservations, registering,
reserving, releasing, clearing and preempting.
- Add the necessary pr-related operation APIs for both the
SCSI protocol and NVMe protocol at the device layer.
- Add scsi driver at the driver layer to verify the functions
Changqi Lu (10):
block: add persistent reservation in/out api
block/raw: add persistent reservation in/out driver
scsi/constant: add persistent reservation in/out protocol constants
scsi/util: add helper functions for persistent reservation types
conversion
hw/scsi: add persistent reservation in/out api for scsi device
block/nvme: add reservation command protocol constants
hw/nvme: add helper functions for converting reservation types
hw/nvme: enable ONCS and rescap function
hw/nvme: add reservation protocal command
block/iscsi: add persistent reservation in/out driver
