2012-09-07monitor: Rename+move net_handle_fd_param -> monitor_handle_fd_paramNicholas Bellinger
This patch renames+moves the net_handle_fd_param() caller used to obtain a file descriptor from either qemu_parse_fd() (the normal case) or from monitor_get_fd() (migration case) into a generically prefixed monitor_handle_fd_param() to be used by vhost-scsi code. Also update net/[socket,tap].c consumers to use the new prefix. Reported-by: Michael S. Tsirkin <mst@redhat.com> Cc: Michael S.

2012-08-02Support 'help' as a synonym for '?' in command line optionsPeter Maydell
For command line options which permit '?' meaning 'please list the permitted values', add support for 'help' as a synonym, by abstracting the check out into a helper function. This change means that in some cases where we were being lazy in our string parsing, "?junk" will now be rejected as an invalid option rather than being (undocumentedly) treated the same way as "?". Update the documentation to use 'help' rather than '?', since '?' is a shell metacharacter and thus prone to fail confusingly if there is a single character filename in the current working directory and the '?' has not been escaped. It's therefore better to steer users towards 'help', though '?' is retained for backwards compatibility. We do not, however, update the output of the system emulator's -help (or any documentation autogenerated from the qemu-options.hx which is the source of the -help text) because libvirt parses our -help output and will break. At a later date when QEMU provides a better interface so libvirt can avoid having to do this, we can update the -help text too.

2012-07-23convert net_client_init() to OptsVisitorLaszlo Ersek
The net_client_init() prototype is kept intact. Based on "is_netdev", the QemuOpts-rooted QemuOpt-list is parsed as a Netdev or a NetLegacy. The original meat of net_client_init() is moved to and simplified in net_client_init1(): Fields not common between -net and -netdev are clearly separated. Getting the name for the init functions is cleaner: Netdev::id is mandatory, and all init functions handle a NULL NetLegacy::name. NetLegacy::vlan explicitly depends on -net (see below). Verifying the "type=" option for -netdev can be turned into a switch. Format validation with qemu_opts_validate() can be removed because the visitor covers it. Relatedly, the "net_client_types" array is reduced to an array of init functions that can be directly indexed by opts->kind. (Help text is available in the schema JSON.) The outermost negation in the condition around qemu_find_vlan() was flattened, because it expresses the dependent code's requirements more clearly. VLAN lookup is avoided if there's no init function to pass the VLAN to. Whenever the value of type=... is needed, we substitute NetClientOptionsKind_lookup[kind]. The individual init functions are not converted yet, thus the original QemuOpts instance is passed transparently. v1->v2: - NetLegacy::name is optional. Tracked it through all init functions: they all handle a NULL name. Updated commit message accordingly. v2->v3: - NetLegacy::id is allowed and takes precedence over NetLegacy::name.

2012-06-07change iov_* function prototypes to be more appropriateMichael Tokarev
Reorder arguments to be more natural, readable and consistent with other iov_* functions, and change argument names, from: iov_from_buf(iov, iov_cnt, buf, iov_off, size) to iov_from_buf(iov, iov_cnt, offset, buf, bytes) The result becomes natural English: copy data to this `iov' vector with `iov_cnt' elements starting at byte offset `offset' from memory buffer `buf', processing `bytes' bytes max. (Try to read the original prototype this way). Also change iov_clear() to more general iov_memset() (it uses memset() internally anyway). While at it, add comments to the header file describing what the routines actually does. The patch only renames argumens in the header, but keeps old names in the implementation. The next patch will touch actual code to match. Now, it might look wrong to pay so much attention to so small things. But we've so many badly designed interfaces already so the whole thing becomes rather confusing or error prone. One example of this is previous commit and small discussion which emerged from it, with an outcome that the utility functions like these aren't well-understdandable, leading to strange usage cases. That's why I paid quite some attention to this set of functions and a few others in subsequent patches. Signed-off-by: Michael Tokarev <mjt@tls.msk.ru>

This function is fully converted to Error (thus, it's "qapi-friendly") 2. qmp_netdev_add(): the QMP front-end for netdev_add(). This is coded by hand and not auto-generated (gen=no in the schema). The reason for this it's a lot easier and simpler to with QemuOpts this way 3. hmp_netdev_add(): HMP front-end. This design was suggested by Paolo Bonzini.

2012-02-01Add support for net bridgeCorey Bryant
The most common use of -net tap is to connect a tap device to a bridge. This requires the use of a script and running qemu as root in order to allocate a tap device to pass to the script. This model is great for portability and flexibility but it's incredibly difficult to eliminate the need to run qemu as root. The only really viable mechanism is to use tunctl to create a tap device, attach it to a bridge as root, and then hand that tap device to qemu. The problem with this mechanism is that it requires administrator intervention whenever a user wants to create a guest. By essentially writing a helper that implements the most common qemu-ifup script that can be safely given cap_net_admin, we can dramatically simplify things for non-privileged users. We still support existing -net tap options as a mechanism for advanced users and backwards compatibility. Currently, this is very Linux centric but there's really no reason why it couldn't be extended for other Unixes. A typical invocation would be similar to one of the following: qemu linux.img -net bridge -net nic,model=virtio qemu linux.img -net tap,helper="/usr/local/libexec/qemu-bridge-helper" -net nic,model=virtio qemu linux.img -netdev bridge,id=hn0 -device virtio-net-pci,netdev=hn0,id=nic1 qemu linux.img -netdev tap,helper="/usr/local/libexec/qemu-bridge-helper",id=hn0 -device virtio-net-pci,netdev=hn0,id=nic1 The default bridge that we attach to is br0. The thinking is that a distro could preconfigure such an interface to allow out-of-the-box bridged networking. Alternatively, if a user wants to use a different bridge, a typical invocation would be simliar to one of the following: qemu linux.img -net bridge,br=qemubr0 -net nic,model=virtio qemu linux.img -net tap,helper="/usr/local/libexec/qemu-bridge-helper --br=qemubr0" -net nic,model=virtio qemu linux.img -netdev bridge,br=qemubr0,id=hn0 -device virtio-net-pci,netdev=hn0,id=nic1 qemu linux.img -netdev tap,helper="/usr/local/libexec/qemu-bridge-helper --br=qemubr0",id=hn0 -device virtio-net-pci,netdev=hn0,id=nic1 Signed-off-by: Anthony Liguori <aliguori@us.ibm.com> Signed-off-by: Richa Marwaha <rmarwah@linux.vnet.ibm.com> Signed-off-by: Corey Bryant <coreyb@linux.vnet.ibm.com> Signed-off-by: Anthony Liguori <aliguori@us.ibm.com>

2011-07-19Fix netdev name lookup in -device, device_add, netdev_delMarkus Armbruster
qemu_find_netdev() looks up members of non_vlan_clients by name. It happily returns the first match. Trouble is the names need not be unique. non_vlan_clients contains host parts (netdevs) and guest parts (NICs). Netdevs have unique names: a netdev's name is a (mandatory) qemu_netdev_opts ID, and these are unique. NIC names are not unique. If a NIC has a qdev ID (which is unique), that's its name. Else, we make up a name. The made-up names are unique, but they can clash with qdev IDs. Even if NICs had unique names, they could still clash with netdev names. Callers of qemu_find_netdev(): * net_init_nic() wants a netdev. It happens to work because it runs before NICs get added to non_vlan_clients. * do_netdev_del() wants a netdev. If it gets a NIC, it complains and fails. Bug: a netdev with the same name that comes later in non_vlan_clients can't be deleted: $ qemu-system-x86_64 -nodefaults -vnc :0 -S -monitor stdio -netdev user,id=hostnet0 -device virtio-net-pci,netdev=hostnet0,id=virtio1 [...] (qemu) netdev_add user,id=virtio1 (qemu) info network Devices not on any VLAN: hostnet0: net=10.0.2.0, restricted=n peer=virtio1 virtio1: model=virtio-net-pci,macaddr=52:54:00:12:34:56 peer=hostnet0 virtio1: net=10.0.2.0, restricted=n (qemu) netdev_del virtio1 Device 'virtio1' not found * parse_netdev() wants a netdev. If it gets a NIC, it gets confused. With the test setup above: (qemu) device_add virtio-net-pci,netdev=virtio1 Property 'virtio-net-pci.netdev' can't take value 'virtio1', it's in use You can even connect two NICs to each other: $ qemu-system-x86_64 -nodefaults -vnc :0 -S -monitor stdio -device virtio-net-pci,id=virtio1 -device e1000,netdev=virtio1 [...] Devices not on any VLAN: virtio1: model=virtio-net-pci,macaddr=52:54:00:12:34:56 peer=e1000.0 e1000.0: model=e1000,macaddr=52:54:00:12:34:57 peer=virtio1 (qemu) q Segmentation fault (core dumped) * do_set_link() works fine for both netdevs and NICs. Whether it really makes sense for netdevs is debatable, but that's outside this patch's scope. Change qemu_find_netdev() to return only netdevs. This fixes the netdev_del and device_add/-device bugs demonstrated above. To avoid changing set_link, make do_set_link() search non_vlan_clients by hand instead of calling qemu_find_netdev(). Signed-off-by: Markus Armbruster <armbru@redhat.com> Signed-off-by: Michael S.

That attempt at diagnosing unused -net nic options failed to account for NICs created via -device; back it out cleanly in preparation for implementing in a different manner.

2011-04-01net: Improve the warnings for dubious command line option combinationsPeter Maydell
Improve the warnings we give if the user specified a combination of -net options which don't make much sense: * Don't warn about anything if the config is the implicit default "-net user -net nic" rather than one specified by the user (this will only kick in for boards with no NIC or if CONFIG_SLIRP is not set) * Diagnose the case where the user asked for NICs which the board didn't instantiate (for example where the user asked for two NICs but the board only supports one) Signed-off-by: Peter Maydell <peter.maydell@linaro.org> Signed-off-by: Aurelien Jarno <aurelien@aurel32.net>
