Socket buffer sizes were hard-coded to 4K for VDE and socket netdevs. Bump this up to 68K (ala tap netdev) to handle maximum GSO packet size (64k) plus plenty of room for the ethernet and virtio_net headers. Originally, ran into this limitation when using -netdev UDP sockets to connect VM-to-VM, where VM interface is configure with MTU=9000. (Using virtio_net NIC model). Test is simple: ping -M do -s 8500 <target>. This test will attempt to ping with unfragmented packet of given size. Without patch, size is limited to < 4K (minus protocol hdrs). With patch, ping test works with pkt size up to 9000 (again, minus protocol hdrs). v2: per Stefan, increase buf size to (4096+65536) as done in tap and apply to vde and socket netdevs. v1: increase buf size to 12K just for -netdev UDP sockets Signed-off-by: NScott Feldman <sfeldma@cumulusnetworks.com> Signed-off-by: NStefan Hajnoczi <stefanha@redhat.com>

Reduce -netdev socket latency by disabling the Nagle algorithm on SOCK_STREAM sockets in net/socket.c. Since we are tunelling Ethernet over TCP we shouldn't artificially delay outgoing packets, let the guest decide packet scheduling. I already get sub-millisecond -netdev socket ping times on localhost, so there was no measurable difference in my testing. This won't hurt though and may improve remote socket performance.

is_tcg_gen_code() checks the upper limit of TCG generated code range wrong, so that TCG could get broken occasionally only when CONFIG_QEMU_LDST_OPTIMIZATION enabled. The reason is code_gen_buffer_max_size does not cover the upper range up to (TCG_MAX_OP_SIZE * OPC_BUF_SIZE), thus code_gen_buffer_max_size should be modified to code_gen_buffer_size.

After this patch, using -drive with an empty file name continues to open the file if driver-specific options are used. If no driver-specific options are specified, the semantics stay as it was: It defines a drive without an inserted medium. In order to achieve this, bdrv_open() must be made safe to work with a NULL filename parameter. The assumption that is made is that only block drivers which implement bdrv_parse_filename() support using driver specific options and could therefore work without a filename. These drivers must make sure to cope with NULL in their implementation of .bdrv_open() (this is only NBD for now). For all other drivers, the block layer code will make sure to error out before calling into their code - they can't possibly work without a filename. Now an NBD connection can be opened like this: qemu-system-x86_64 -drive file.driver=nbd,file.port=1234,file.host=::1 Signed-off-by: NKevin Wolf <kwolf@redhat.com> Reviewed-by: NEric Blake <eblake@redhat.com>

If a driver needs structured data and not just a string, it can provide a .bdrv_parse_filename callback now that parses the command line string into separate options. Keeping this separate from .bdrv_open_filename ensures that the preferred way of directly specifying the options always works as well if parsing the string works.

The existing parsers for the file name now parse everything into the bdrv_open() options QDict. Instead of using these parsers, you can now directly specify the options on the command line, like this: qemu-system-x86_64 -drive file=nbd:,file.port=1234,file.host=::1 Clearly the file=... part could use further improvement, but it's a start.

The NBD block supports an URL syntax, for which a URL parser returns separate hostname and port fields. It also supports the traditional qemu syntax encoded in a filename. Until now, after parsing the URL to get each piece of information, a new string is built to be fed to socket functions. Instead of building a string in the URL case that is immediately parsed again, parse the string in both cases and use the QemuOpts interface to qemu-sockets.c.
