2019-09-04libvhost-user: fix SLAVE_SEND_FD handlingJohannes Berg
It doesn't look like this could possibly work properly since VHOST_USER_PROTOCOL_F_SLAVE_SEND_FD is defined to 10, but the dev->protocol_features has a bitmap. I suppose the peer this was tested with also supported VHOST_USER_PROTOCOL_F_LOG_SHMFD, in which case the test would always be false, but nevertheless the code seems wrong.

2019-07-22contrib/elf2dmp: Build download.o with CURL_CFLAGSPeter Maydell
contrib/elf2dmp has a source file which uses curl/curl.h; although we link the final executable with CURL_LIBS, we forgot to build this source file with CURL_CFLAGS, so if the curl header is in a place that's not already on the system include path then it will fail to build. Add a line specifying the cflags needed for download.o; while we are here, bring the specification of the libs into line with this, since using a per-object variable setting is preferred over adding them to the final executable link line.

2019-07-04libvhost-user: implement VHOST_USER_PROTOCOL_F_MQStefan Hajnoczi
Existing vhost-user device backends, including vhost-user-scsi and vhost-user-blk, support multiqueue but libvhost-user currently does not advertise this. VHOST_USER_PROTOCOL_F_MQ enables the VHOST_USER_GET_QUEUE_NUM request needed for a vhost-user master to query the number of queues. For example, QEMU's vhost-user-net master depends on VHOST_USER_PROTOCOL_F_MQ for multiqueue. If you're wondering how any device backend with more than one virtqueue functions today, it's because device types with a fixed number of virtqueues do not require querying the number of queues. Therefore the vhost-user master for vhost-user-input with 2 virtqueues, for example, doesn't actually depend on VHOST_USER_PROTOCOL_F_MQ. It just enables virtqueues 0 and 1 without asking. Let there be multiqueue!

2019-07-04libvhost-user: support many virtqueuesStefan Hajnoczi
Currently libvhost-user is hardcoded to at most 8 virtqueues. The device backend should decide the number of virtqueues, not libvhost-user. This is important for multiqueue device backends where the guest driver needs an accurate number of virtqueues. This change breaks libvhost-user and libvhost-user-glib API stability. There is no stability guarantee yet, so make this change now and update all in-tree library users. This patch touches up vhost-user-blk, vhost-user-gpu, vhost-user-input, vhost-user-scsi, and vhost-user-bridge. If the device has a fixed number of queues that exact number is used. Otherwise the previous default of 8 virtqueues is used. vu_init() and vug_init() can now fail if malloc() returns NULL. I considered aborting with an error in libvhost-user but it should be safe to instantiate new vhost-user instances at runtime without risk of terminating the process. Therefore callers need to handle the vu_init() failure now. vhost-user-blk and vhost-user-scsi duplicate virtqueue index checks that are already performed by libvhost-user. This code would need to be modified to use max_queues but remove it completely instead since it's redundant.

2019-07-04libvhost-user: add vmsg_set_reply_u64() helperStefan Hajnoczi
The VhostUserMsg request is reused as the reply by message processing functions. This is risky since request fields may corrupt the reply if the vhost-user message handler function forgets to re-initialize them. Changing this practice would be very invasive but we can introduce a helper function to make u64 payload replies safe. This also eliminates code duplication in message processing functions.

Add a new vhost-user message to give a unix socket to a vhost-user backend for GPU display updates. Back when I started that work, I added a new GPU channel because the vhost-user protocol wasn't bidirectional. Since then, there is a vhost-user-slave channel for the slave to send requests to the master. We could extend it with GPU messages. However, the GPU protocol is quite orthogonal to vhost-user, thus I chose to have a new dedicated channel. See vhost-user-gpu.rst for the protocol details.

2019-03-12libvhost-user: exit by default on VHOST_USER_NONEMarc-André Lureau
Since commit 2566378d6d13bf4d28c7770bdbda5f7682594bbe, libvhost-user no longer panics on disconnect (rc == 0), and instead silently ignores an invalid VHOST_USER_NONE message. Without extra work from the API user, this will simply busy-loop on HUP events. The obvious thing to do is to exit(0) instead, while additional or different work can be done by overriding iface->process_msg().
