[Qemu-devel] [PATCH 1/8] block-migration: acquire AioContext as necessary

This is needed because dataplane will run during block migration as well. The block device migration code is quite liberal in taking the iothread mutex. For simplicity, keep it the same way, even though one could actually choose between the BQL (for regular BlockDriverStates) and the AioContext

[Qemu-devel] [PATCH 2/8] vring: make vring_enable_notification return void

[Qemu-devel] [PATCH 5/8] virtio-blk: fix "disabled data plane" mode

In disabled mode, virtio-blk dataplane seems to be enabled, but flow actually goes through the normal virtio path. This patch simplifies a bit the handling of disabled mode. In disabled mode, virtio_blk_handle_output might be called even if s->dataplane is not NULL. This is a bit tricky,

[Qemu-devel] [PATCH 4/8] virtio: export vring_notify as virtio_should_notify

[Qemu-devel] [PATCHv7 2/9] slirp: Adding ICMPv6 error sending

From: Yann Bordenave Disambiguation : icmp_error is renamed into icmp_send_error, since it doesn't manage errors, but only sends ICMP Error messages. Adding icmp6_send_error to send ICMPv6 Error messages. This function is simpler than the v4 version. Adding some calls in

[Qemu-devel] [PATCHv7 4/9] slirp: Factorizing tcpiphdr structure with an union

From: Guillaume Subiron This patch factorizes the tcpiphdr structure to put the IPv4 fields in an union, for addition of version 6 in further patch. Using some macros, retrocompatibility of the existing code is assured. This patch also fixes the SLIRP_MSIZE and margin

[Qemu-devel] [PATCHv8 0/9] slirp: Adding IPv6 support to Qemu -net user mode

Hello, This is another respin of IPv6 in Qemu -net user mode. These patches add ICMPv6, NDP, and make UDP and TCP compatible with IPv6. Difference with version 7 is: - Fix overflow detection in strtol call - Fix formatting and typos - Use SLIRP_ prefix for header protection - Use grand

[Qemu-devel] [PATCHv7 3/9] slirp: Adding IPv6 UDP support

From: Guillaume Subiron This adds the sin6 case in the fhost and lhost unions and related macros. It adds udp6_input() and udp6_output(). It adds the IPv6 case in sorecvfrom(). Finally, udp_input() is called by ip6_input(). Signed-off-by: Guillaume Subiron

[Qemu-devel] [PATCHv7 5/9] slirp: Generalizing and neutralizing various TCP functions before adding IPv6 stuff

From: Guillaume Subiron Basically, this patch adds some switch in various TCP functions to prepare them for the IPv6 case. To have something to "switch" in tcp_input() and tcp_respond(), a new argument is used to give them the sa_family of the addresses they are working on.
