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 block/block-backend.c | 403 ++++++++++++++++++++++++++++ block/io.c | 164 ++++++++++++ block/iscsi.c | 425 ++++++++++++++++++++++++++++++ block/raw-format.c | 56 ++++ hw/nvme/ctrl.c | 326 ++++++++++++++++++++++- hw/nvme/ns.c | 5 + hw/nvme/nvme.h | 88 +++++++ hw/scsi/scsi-disk.c | 368 ++++++++++++++++++++++++++ include/block/block-common.h | 40 +++ include/block/block-io.h | 20 ++ include/block/block_int-common.h | 84 ++++++ include/block/nvme.h | 100 ++++++- include/scsi/constants.h | 52 ++++ include/scsi/utils.h | 8 + include/sysemu/block-backend-io.h | 24 ++ scsi/utils.c | 81 ++++++ 16 files changed, 2241 insertions(+), 3 deletions(-)
