2021-03-17plugins: expand kernel-doc for qemu_info_tAlex Bennée1-7/+15
It seems kernel-doc struggles a bit with typedef structs but with enough encouragement we can get something out of it. Signed-off-by: Alex Bennée <alex.bennee@linaro.org> Message-Id: <20210312172821.31647-5-alex.bennee@linaro.org>
2021-03-17plugins: Expose physical addresses instead of device offsetsAaron Lindsay4-14/+39
This allows plugins to query for full virtual-to-physical address translation for a given `qemu_plugin_hwaddr` and stops exposing the offset within the device itself. As this change breaks the API, QEMU_PLUGIN_VERSION is incremented.

2021-03-17plugins: new syscalls pluginMatthias Weckbecker2-1/+50
This commit adds a new syscalls plugin that displays the syscalls as they are executed and returned. This plugin outputs the number of the syscall as well as the syscall return value. Works in *-user only. Essentially, this commit restores: https://lists.gnu.org/archive/html/qemu-devel/2018-06/msg00846.html by using the new QEMU plugin API.

2021-03-15usb: Un-deprecate -usbdevice (except for -usbdevice audio which gets removed)Thomas Huth4-12/+8
When trying to remove the -usbdevice option, there were complaints that "-usbdevice braille" is still a very useful shortcut for some people. Thus we never remove this option. Since it's not such a big burden to keep it around, and it's also convenient in the sense that you don't have to worry to enable a host controller explicitly with this option, we should remove it from he deprecation list again. However, there is one exception: "-usbdevice audio" should go away, since audio devices without "audiodev=..." parameter are also on the deprecation list and you cannot use "-usbdevice audio" with "audiodev".

2021-03-15qapi: net: Add query-netdev commandAlexey Kirillov12-9/+477
The query-netdev command is used to get the configuration of the current network device backends (netdevs). This is the QMP analog of the HMP command "info network" but only for netdevs (i.e. excluding NIC and hubports). The query-netdev command returns an array of objects of the NetdevInfo type, which are an extension of Netdev type. It means that response can be used for netdev-add after small modification. This can be useful for recreate the same netdev configuration. Information about the network device is filled in when it is created or modified and is available through the NetClientState->stored_config.

2021-03-15pvrdma: wean code off pvrdma_ring.h kernel headerCornelia Huck7-144/+38
The pvrdma code relies on the pvrdma_ring.h kernel header for some basic ring buffer handling. The content of that header isn't very exciting, but contains some (q)atomic_*() invocations that (a) cause manual massaging when doing a headers update, and (b) are an indication that we probably should not be importing that header at all. Let's reimplement the ring buffer handling directly in the pvrdma code instead. This arguably also improves readability of the code. Importing the header can now be dropped.

2021-03-15net: introduce qemu_receive_packet()Jason Wang4-7/+66
Some NIC supports loopback mode and this is done by calling nc->info->receive() directly which in fact suppresses the effort of reentrancy check that is done in qemu_net_queue_send(). Unfortunately we can't use qemu_net_queue_send() here since for loopback there's no sender as peer, so this patch introduce a qemu_receive_packet() which is used for implementing loopback mode for a NIC with this check. NIC that supports loopback mode will be converted to this helper. This is intended to address CVE-2021-3416.

2021-03-15net: validate that ids are well formedPaolo Bonzini1-0/+5
When a network or network device is created from the command line or HMP, QemuOpts ensures that the id passes the id_wellformed check. However, QMP skips this: $ qemu-system-x86_64 -qmp stdio -S -nic user,id=123/456 qemu-system-x86_64: -nic user,id=123/456: Parameter id expects an identifier Identifiers consist of letters, digits, -, ., _, starting with a letter. $ qemu-system-x86_64 -qmp stdio -S {"execute":"qmp_capabilities"} {"return": {}} {"execute":"netdev_add", "arguments": {"type": "user", "id": "123/456"}} {"return": {}} After: $ qemu-system-x86_64 -qmp stdio -S {"execute":"qmp_capabilities"} {"return": {}} {"execute":"netdev_add", "arguments": {"type": "user", "id": "123/456"}} {"error": {"class": "GenericError", "desc": "Parameter "id" expects an identifier"}} Validity checks should be performed always at the bottom of the call chain, because QMP skips all the steps above. At the same time we know that every call chain should go through either QMP or (for legacy) through QemuOpts. Because the id for -net and -nic is automatically generated and not well-formed by design, just add the check to QMP.

2021-03-15virtio-net: calculating proper msix vectors on initJason Wang2-1/+10
Currently, the default msix vectors for virtio-net-pci is 3 which is obvious not suitable for multiqueue guest, so we depends on the user or management tools to pass a correct vectors parameter. In fact, we can simplifying this by calculating the number of vectors on realize. Consider we have N queues, the number of vectors needed is 2*N + 2 (#queue pairs + plus one config interrupt and control vq). We didn't check whether or not host support control vq because it was added unconditionally by qemu to avoid breaking legacy guests such as Minix.
