2021-03-15net: Do not fill legacy info_str for backendsAlexey Kirillov
As we use QAPI NetClientState->stored_config to store and get information about backend network devices, we can drop fill of legacy field info_str for them. We still use info_str field for NIC and hubports, so we can not completely remove it. Signed-off-by: Alexey Kirillov <lekiravi@yandex-team.ru> Signed-off-by: Jason Wang <jasowang@redhat.com>
2021-03-15hmp: Use QAPI NetdevInfo in hmp_info_networkAlexey Kirillov
Replace usage of legacy field info_str of NetClientState for backend network devices with QAPI NetdevInfo stored_config that already used in QMP query-netdev. This change increases the detail of the "info network" output and takes a more general approach to composing the output. NIC and hubports still use legacy info_str field.

2021-03-15net: Move NetClientState.info_str to dynamic allocationsAlexey Kirillov
The info_str field of the NetClientState structure is static and has a size of 256 bytes. This amount is often unclaimed, and the field itself is used exclusively for HMP "info network". The patch translates info_str to dynamic memory allocation. This action is also allows us to painlessly discard usage of this field for backend devices.

2021-03-15qapi: net: Add query-netdev commandAlexey Kirillov
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.

2021-03-15net: introduce qemu_receive_packet()Jason Wang
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 Bonzini
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.

2021-01-28net: Clarify early exit conditionEric Blake
On first glance, the loop in qmp_query_rx_filter() has early return paths that could leak any allocation of filter_list from a previous iteration. But on closer inspection, it is obvious that all of the early exits are guarded by has_name, and that the bulk of the loop body can be executed at most once if the user is filtering by name, thus, any early exit coincides with an empty list. Add asserts to make this obvious.

2021-01-25net: checksum: Introduce fine control over checksum typeBin Meng
At present net_checksum_calculate() blindly calculates all types of checksums (IP, TCP, UDP). Some NICs may have a per type setting in their BDs to control what checksum should be offloaded. To support such hardware behavior, introduce a 'csum_flag' parameter to the net_checksum_calculate() API to allow fine control over what type checksum is calculated. Existing users of this API are updated accordingly. Signed-off-by: Bin Meng <bin.meng@windriver.com> Signed-off-by: Jason Wang <jasowang@redhat.com>
2021-01-25net: checksum: Add IP header checksum calculationGuishan Qin
At present net_checksum_calculate() only calculates TCP/UDP checksum in an IP packet, but assumes the IP header checksum to be provided by the software, e.g.: Linux kernel always calculates the IP header checksum. However this might not always be the case, e.g.: for an IP checksum offload enabled stack like VxWorks, the IP header checksum can be zero. This adds the checksum calculation of the IP header.

2021-01-25net: checksum: Skip fragmented IP packetsMarkus Carlstedt
To calculate the TCP/UDP checksum we need the whole datagram. Unless the hardware has some logic to collect all fragments before sending the whole datagram first, it can only be done by the network stack, which is normally the case for the NICs we have seen so far.

2021-01-25net: Fix handling of id in netdev_add and netdev_delMarkus Armbruster
CLI -netdev accumulates in option group "netdev". Before commit 08712fcb85 "net: Track netdevs in NetClientState rather than QemuOpt", netdev_add added to the option group, and netdev_del removed from it, both HMP and QMP. Thus, every netdev had a corresponding QemuOpts in this option group. Commit 08712fcb85 dropped this for QMP netdev_add and both netdev_del. Now a netdev has a corresponding QemuOpts only when it was created with CLI or HMP. Two issues: * QMP and HMP netdev_del can leave QemuOpts behind, breaking HMP netdev_add. Reproducer: $ qemu-system-x86_64 -S -display none -nodefaults -monitor stdio QEMU 5.1.92 monitor - type 'help' for more information (qemu) netdev_add user,id=net0 (qemu) info network net0: index=0,type=user,net=10.0.2.0,restrict=off (qemu) netdev_del net0 (qemu) info network (qemu) netdev_add user,id=net0 upstream-qemu: Duplicate ID 'net0' for netdev Try "help netdev_add" for more information Fix by restoring the QemuOpts deletion in qmp_netdev_del(), but with a guard, because the QemuOpts need not exist. * QMP netdev_add loses its "no duplicate ID" check. Reproducer: $ qemu-system-x86_64 -S -display none -qmp stdio {"QMP": {"version": {"qemu": {"micro": 92, "minor": 1, "major": 5}, "package": "v5.2.0-rc2-1-g02c1f0142c"}, "capabilities": ["oob"]}} {"execute": "qmp_capabilities"} {"return": {}} {"execute": "netdev_add", "arguments": {"type": "user", "id":"net0"}} {"return": {}} {"execute": "netdev_add", "arguments": {"type": "user", "id":"net0"}} {"return": {}} Fix by adding a duplicate ID check to net_client_init1() to replace the lost one. The check is redundant for callers where QemuOpts still checks, i.e. for CLI and HMP.

this fixes non-TCG builds broken recently by replay reverse debugging. Stub the needed functions in stub/, splitting roughly between functions needed only by system emulation, by system emulation and tools, and by everyone. This includes duplicating some code in replay/, and puts the logic for non-replay related events in the replay/ module (+ the stubs), so this should be revisited in the future. Surprisingly, only _one_ qtest was affected by this, ide-test.c, which resulted in a buzz as the bh events were never delivered, and the bh never executed. Many other subsystems _should_ have been affected. This fixes the immediate issue, however a better way to group replay functionality to TCG-only code could be developed in the long term.

2020-10-09monitor: Use getter/setter functions for cur_monKevin Wolf
cur_mon really needs to be coroutine-local as soon as we move monitor command handlers to coroutines and let them yield. As a first step, just remove all direct accesses to cur_mon so that we can implement this in the getter function later.

2020-10-06slirp: Convert Makefile bits to meson bitsPaolo Bonzini
SLIRP uses Meson so it could become a subproject in the future, but our choice of configure options is not yet supported in Meson (https://github.com/mesonbuild/meson/pull/7740). For now, build the library via the main meson.build just like for capstone. This improves the current state of affairs in that we will re-link the qemu executables against a changed libslirp.a, which we wouldn't do before-hand.

2020-09-29vhost-user: save features of multiqueues if chardev is closedhaibinzhang(张海斌)
Fore-commit(c6beefd674) only saves features of queue0, this makes wrong features of other queues in multiqueues situation. For examples: qemu-system-aarch64 ... \ -chardev socket,id=charnet0,path=/var/run/vhost_sock \ -netdev vhost-user,chardev=charnet0,queues=2,id=hostnet0 \ ... There are two queues in nic assocated with one chardev. When chardev is reconnected, it is necessary to save and restore features of all queues.
