2017-07-17net/filter-rewriter.c: Make filter-rewriter support vnet_hdr_lenZhang Chen
We add the vnet_hdr_support option for filter-rewriter, default is disabled. If you use virtio-net-pci or other driver needs vnet_hdr, please enable it. You can use it for example: -object filter-rewriter,id=rew0,netdev=hn0,queue=all,vnet_hdr_support We get the vnet_hdr_len from NetClientState that make us parse net packet correctly.

2017-06-07Revert "Change net/socket.c to use socket_*() functions" againDaniel P. Berrange
This reverts commit 883e4f7624e10b98d16d9adaffb8b1795664d899. This code changed net/socket.c from using socket()+connect(), to using socket_connect(). In theory this is great, but in practice this has completely broken the ability to connect the frontend and backend: $ ./x86_64-softmmu/qemu-system-x86_64 \ -device e1000,id=e0,netdev=hn0,mac=DE:AD:BE:EF:AF:05 \ -netdev socket,id=hn0,connect=localhost:1234 qemu-system-x86_64: -device e1000,id=e0,netdev=hn0,mac=DE:AD:BE:EF:AF:05: Property 'e1000.netdev' can't find value 'hn0' The old code would call net_socket_fd_init() synchronously, while letting the connect() complete in the backgorund. The new code moved net_socket_fd_init() so that it is only called after connect() completes in the background. Thus at the time we initialize the NIC frontend, the backend does not exist. The socket_connect() conversion as done is a bad fit for the current code, since it did not try to change the way it deals with async connection completion. Rather than try to fix this, just revert the socket_connect() conversion entirely. The code is about to be converted to use QIOChannel which will let the problem be solved in a cleaner manner. This revert is more suitable for stable branches in the meantime. Signed-off-by: Daniel P.

2017-06-02char: make chr_fe_deinit() optionaly delete backendMarc-André Lureau

2017-02-22net: Flatten simple union NetLegacyOptionsMarkus Armbruster
Simple unions are simpler than flat unions in the schema, but more complicated in C and on the QMP wire: there's extra indirection in C and extra nesting on the wire, both pointless. They're best avoided in new code. NetLegacyOptions isn't new, but it's only used internally, not in QMP. Convert it to a flat union.
