2017-01-10vhost-user: Add MTU protocol feature and opMaxime Coquelin
This patch implements VHOST_USER_PROTOCOL_F_NET_MTU protocol feature and VHOST_USER_NET_SET_MTU request so that the backend gets notified of the user defined host MTU. If backend supports VHOST_USER_PROTOCOL_F_REPLY_ACK, QEMU assumes MTU is valid if success is returned. Vhost-net driver sends this request through a new vhost_net_set_mtu vhost_ops entry.

2017-01-06record/replay: add network supportPavel Dovgalyuk
This patch adds support of recording and replaying network packets in irount rr mode. Record and replay for network interactions is performed with the network filter. Each backend must have its own instance of the replay filter as follows: -netdev user,id=net1 -device rtl8139,netdev=net1 -object filter-replay,id=replay,netdev=net1 Replay network filter is used to record and replay network packets. While recording the virtual machine this filter puts all packets coming from the outer world into the log. In replay mode packets from the log are injected into the network device. All interactions with network backend in replay mode are disabled. v5 changes: - using iov_to_buf function instead of loop Signed-off-by: Pavel Dovgalyuk <pavel.dovgaluk@ispras.ru> Signed-off-by: Jason Wang <jasowang@redhat.com>

2016-11-14block/curl: Drop TFTP "support"Max Reitz
Because TFTP does not support byte ranges, it was never usable with our curl block driver. Since apparently nobody has ever complained loudly enough for someone to take care of the issue until now, it seems reasonable to assume that nobody has ever actually used it. Therefore, it should be safe to just drop it from curl's protocol list. [Jeff Cody: Below is additional summary pulled, with some rewording, from followup emails between Max and Markus, to explain what worked and what didn't] TFTP would sometimes work, to a limited extent, for images <= the curl "readahead" size, so long as reads started at offset zero. By default, that readahead size is 256KB. Reads starting at a non-zero offset would also have returned data from a zero offset. It can become more complicated still, with mixed reads at zero offset and non-zero offsets, due to data buffering. In short, TFTP could only have worked before in very specific scenarios with unrealistic expectations and constraints.

2016-10-07block: Add qdev ID to DEVICE_TRAY_MOVEDKevin Wolf
The event currently only contains the BlockBackend name. However, with anonymous BlockBackends, this is always the empty string. Add the qdev ID (or if none was given, the QOM path) so that the user can still see which device caused the event. Event generation has to be moved from bdrv_eject() to the BlockBackend because the BDS doesn't know the attached device, but that's easy because blk_eject() is the only user of it.

2016-09-27cpus-common: lock-free fast path for cpu_exec_start/endPaolo Bonzini
Set cpu->running without taking the cpu_list lock, only requiring it if there is a concurrent exclusive section. This requires adding a new field to CPUState, which records whether a running CPU is being counted in pending_cpus. When an exclusive section is started concurrently with cpu_exec_start, cpu_exec_start can use the new field to determine if it has to wait for the end of the exclusive section. Likewise, cpu_exec_end can use it to see if start_exclusive is waiting for that CPU. This a separate patch for easier bisection of issues. Signed-off-by: Paolo Bonzini <pbonzini@redhat.com>
2016-09-27cpus-common: simplify locking for start_exclusive/end_exclusivePaolo Bonzini
It is not necessary to hold qemu_cpu_list_mutex throughout the exclusive section, because no other exclusive section can run while pending_cpus != 0. exclusive_idle() is called in cpu_exec_start(), and that prevents any CPUs created after start_exclusive() from entering cpu_exec() during an exclusive section.

2016-09-27cpus-common: remove redundant call to exclusive_idle()Paolo Bonzini
No need to call exclusive_idle() from cpu_exec_end since it is done immediately afterwards in cpu_exec_start. Any exclusive section could run as soon as cpu_exec_end leaves, because cpu->running is false and the mutex is not taken, so the call does not add any protection either.
