When MSECCFG.MML is set, after checking the address range in PMP if the asked permissions are not same as programmed in PMP, the default permissions are applied. This should only be the case when there is no matching address is found. This patch skips applying default rules when matching address range is found. It returns the index of the match PMP entry.

2023-02-23block/rbd: Add support for layered encryptionOr Ozeri
Starting from ceph Reef, RBD has built-in support for layered encryption, where each ancestor image (in a cloned image setting) can be possibly encrypted using a unique passphrase. A new function, rbd_encryption_load2, was added to librbd API. This new function supports an array of passphrases (via "spec" structs). This commit extends the qemu rbd driver API to use this new librbd API, in order to support this new layered encryption feature.

2023-02-23virtio-scsi: reset SCSI devices from main loop threadStefan Hajnoczi
When an IOThread is configured, the ctrl virtqueue is processed in the IOThread. TMFs that reset SCSI devices are currently called directly from the IOThread and trigger an assertion failure in blk_drain() from the following call stack: virtio_scsi_handle_ctrl_req -> virtio_scsi_do_tmf -> device_code_reset -> scsi_disk_reset -> scsi_device_purge_requests -> blk_drain ../block/block-backend.c:1780: void blk_drain(BlockBackend *): Assertion `qemu_in_main_thread()' failed. The blk_drain() function is not designed to be called from an IOThread because it needs the Big QEMU Lock (BQL). This patch defers TMFs that reset SCSI devices to a Bottom Half (BH) that runs in the main loop thread under the BQL. This way it's safe to call blk_drain() and the assertion failure is avoided. Introduce s->tmf_bh_list for tracking TMF requests that have been deferred to the BH. When the BH runs it will grab the entire list and process all requests. Care must be taken to clear the list when the virtio-scsi device is reset or unrealized. Otherwise deferred TMF requests could execute later and lead to use-after-free or other undefined behavior. The s->resetting counter that's used by TMFs that reset SCSI devices is accessed from multiple threads. This patch makes that explicit by using atomic accessor functions. With this patch applied the counter is only modified by the main loop thread under the BQL but can be read by any thread.

2023-02-23dma-helpers: prevent dma_blk_cb() vs dma_aio_cancel() raceStefan Hajnoczi
dma_blk_cb() only takes the AioContext lock around ->io_func(). That means the rest of dma_blk_cb() is not protected. In particular, the DMAAIOCB field accesses happen outside the lock. There is a race when the main loop thread holds the AioContext lock and invokes scsi_device_purge_requests() -> bdrv_aio_cancel() -> dma_aio_cancel() while an IOThread executes dma_blk_cb(). The dbs->acb field determines how cancellation proceeds. If dma_aio_cancel() sees dbs->acb == NULL while dma_blk_cb() is still running, the request can be completed twice (-ECANCELED and the actual return value). The following assertion can occur with virtio-scsi when an IOThread is used: ../hw/scsi/scsi-disk.c:368: scsi_dma_complete: Assertion `r->req.aiocb != NULL' failed. Fix the race by holding the AioContext across dma_blk_cb(). Now dma_aio_cancel() under the AioContext lock will not see inconsistent/intermediate states.

This adds GRAPH_RDLOCK annotations to declare that callers of bdrv_co_is_inserted() need to hold a reader lock for the graph. blk_is_inserted() is done as a co_wrapper_mixed_bdrv_rdlock (unlike most other blk_* functions) because it is called a lot from other blk_co_*() functions that already hold the lock. These calls go through blk_is_available(), which becomes a co_wrapper_mixed_bdrv_rdlock, too, for the same reason. Functions that run in a coroutine and can call bdrv_co_is_available() directly are changed to do so, which results in better TSA coverage.

2023-02-23mirror: Fix access of uninitialised fields during startKevin Wolf
bdrv_mirror_top_pwritev() accesses the job object when active mirroring is enabled. It disables this code during early initialisation while s->job isn't set yet. However, s->job is still set way too early when the job object isn't fully initialised. For example, &s->ops_in_flight isn't initialised yet and the in_flight bitmap doesn't exist yet. This causes crashes when a write request comes in too early. Move the assignment of s->job to when the mirror job is actually fully initialised to make sure that the mirror_top driver doesn't access it too early.
