2020-11-03Revert "vhost-blk: set features before setting inflight feature"Stefan Hajnoczi1-6/+0
This reverts commit adb29c027341ba095a3ef4beef6aaef86d3a520e. The commit broke -device vhost-user-blk-pci because the vhost_dev_prepare_inflight() function it introduced segfaults in vhost_dev_set_features() when attempting to access struct vhost_dev's vdev pointer before it has been assigned. To reproduce the segfault simply launch a vhost-user-blk device with the contrib vhost-user-blk device backend: $ build/contrib/vhost-user-blk/vhost-user-blk -s /tmp/vhost-user-blk.sock -r -b /var/tmp/foo.img $ build/qemu-system-x86_64 \ -device vhost-user-blk-pci,id=drv0,chardev=char1,addr=4.0 \ -object memory-backend-memfd,id=mem,size=1G,share=on \ -M memory-backend=mem,accel=kvm \ -chardev socket,id=char1,path=/tmp/vhost-user-blk.sock Segmentation fault (core dumped) Cc: Jin Yu <jin.yu@intel.com> Cc: Raphael Norwitz <raphael.norwitz@nutanix.com> Cc: Michael S.

2020-10-27hw/block/nvme: change controller pci idKlaus Jensen2-2/+11
There are two reasons for changing this: 1. The nvme device currently uses an internal Intel device id. 2. Since commits "nvme: fix write zeroes offset and count" and "nvme: support multiple namespaces" the controller device no longer has the quirks that the Linux kernel think it has. As the quirks are applied based on pci vendor and device id, change them to get rid of the quirks. To keep backward compatibility, add a new 'use-intel-id' parameter to the nvme device to force use of the Intel vendor and device id. This is off by default but add a compat property to set this for 5.1 machines and older. If a 5.1 machine is booted (or the use-intel-id parameter is explicitly set to true), the Linux kernel will just apply these unnecessary quirks: 1. NVME_QUIRK_IDENTIFY_CNS which says that the device does not support anything else than values 0x0 and 0x1 for CNS (Identify Namespace and Identify Namespace). With multiple namespace support, this just means that the kernel will "scan" namespaces instead of using "Active Namespace ID list" (CNS 0x2). 2. NVME_QUIRK_DISABLE_WRITE_ZEROES. The nvme device started out with a broken Write Zeroes implementation which has since been fixed in commit 9d6459d21a6e ("nvme: fix write zeroes offset and count").

2020-10-27hw/block/nvme: support multiple namespacesKlaus Jensen6-114/+426
This adds support for multiple namespaces by introducing a new 'nvme-ns' device model. The nvme device creates a bus named from the device name ('id'). The nvme-ns devices then connect to this and registers themselves with the nvme device. This changes how an nvme device is created. Example with two namespaces: -drive file=nvme0n1.img,if=none,id=disk1 -drive file=nvme0n2.img,if=none,id=disk2 -device nvme,serial=deadbeef,id=nvme0 -device nvme-ns,drive=disk1,bus=nvme0,nsid=1 -device nvme-ns,drive=disk2,bus=nvme0,nsid=2 The drive property is kept on the nvme device to keep the change backward compatible, but the property is now optional. Specifying a drive for the nvme device will always create the namespace with nsid 1.

Handling DMA errors gracefully is required for the device to pass the block/011 test ("disable PCI device while doing I/O") in the blktests suite. With this patch the device sets the Controller Fatal Status bit in the CSTS register when failing to read from a submission queue or writing to a completion queue; expecting the host to reset the controller. If DMA errors occur at any other point in the execution of the command (say, while mapping the PRPs), the command is aborted with a Data Transfer Error status code.

2020-09-29vhost: recheck dev state in the vhost_migration_log routineDima Stepanov1-3/+16
vhost-user devices can get a disconnect in the middle of the VHOST-USER handshake on the migration start. If disconnect event happened right before sending next VHOST-USER command, then the vhost_dev_set_log() call in the vhost_migration_log() function will return error. This error will lead to the assert() and close the QEMU migration source process. For the vhost-user devices the disconnect event should not break the migration process, because: - the device will be in the stopped state, so it will not be changed during migration - if reconnect will be made the migration log will be reinitialized as part of reconnect/init process: #0 vhost_log_global_start (listener=0x563989cf7be0) at hw/virtio/vhost.c:920 #1 0x000056398603d8bc in listener_add_address_space (listener=0x563989cf7be0, as=0x563986ea4340 <address_space_memory>) at softmmu/memory.c:2664 #2 0x000056398603dd30 in memory_listener_register (listener=0x563989cf7be0, as=0x563986ea4340 <address_space_memory>) at softmmu/memory.c:2740 #3 0x0000563985fd6956 in vhost_dev_init (hdev=0x563989cf7bd8, opaque=0x563989cf7e30, backend_type=VHOST_BACKEND_TYPE_USER, busyloop_timeout=0) at hw/virtio/vhost.c:1385 #4 0x0000563985f7d0b8 in vhost_user_blk_connect (dev=0x563989cf7990) at hw/block/vhost-user-blk.c:315 #5 0x0000563985f7d3f6 in vhost_user_blk_event (opaque=0x563989cf7990, event=CHR_EVENT_OPENED) at hw/block/vhost-user-blk.c:379 Update the vhost-user-blk device with the internal started_vu field which will be used for initialization (vhost_user_blk_start) and clean up (vhost_user_blk_stop). This additional flag in the VhostUserBlk structure will be used to track whether the device really needs to be stopped and cleaned up on a vhost-user level. The disconnect event will set the overall VHOST device (not vhost-user) to the stopped state, so it can be used by the general vhost_migration_log routine. Such approach could be propogated to the other vhost-user devices, but better idea is just to make the same connect/disconnect code for all the vhost-user devices.

Some trace points are attributed to the wrong source file. Happens when we neglect to update trace-events for code motion, or add events in the wrong place, or misspell the file name. Clean up with help of scripts/cleanup-trace-events.pl. Funnies requiring manual post-processing: * accel/tcg/cputlb.c trace points are in trace-events. * block.c and blockdev.c trace points are in block/trace-events. * hw/block/nvme.c uses the preprocessor to hide its trace point use from cleanup-trace-events.pl. * hw/tpm/tpm_spapr.c uses pseudo trace point tpm_spapr_show_buffer to guard debug code. * include/hw/xen/xen_common.h trace points are in hw/xen/trace-events. * linux-user/trace-events abbreviates a tedious list of filenames to */signal.c. * net/colo-compare and net/filter-rewriter.c use pseudo trace points colo_compare_miscompare and colo_filter_rewriter_debug to guard debug code.

2020-09-09Move QOM typedefs and add missing includesEduardo Habkost4-14/+25
Some typedefs and macros are defined after the type check macros. This makes it difficult to automatically replace their definitions with OBJECT_DECLARE_TYPE. Patch generated using: $ ./scripts/codeconverter/converter.py -i \ --pattern=QOMStructTypedefSplit $(git grep -l '' -- '*.[ch]') which will split "typdef struct { ... } TypedefName" declarations. Followed by: $ ./scripts/codeconverter/converter.py -i --pattern=MoveSymbols \ $(git grep -l '' -- '*.[ch]') which will: - move the typedefs and #defines above the type check macros - add missing #include "qom/object.h" lines if necessary Reviewed-by: Daniel P.

2020-09-02hw/block/nvme: verify validity of prp lists in the cmbKlaus Jensen1-1/+13
Before this patch the device already supported PRP lists in the CMB, but it did not check for the validity of it nor announced the support in the Identify Controller data structure LISTS field. If some of the PRPs in a PRP list are in the CMB, then ALL entries must be there. This patch makes sure that requirement is verified as well as properly announcing support for PRP lists in the CMB.
