After commit 761876c857cb ("tap: XDP support"), we can actually queueing XDP pointers in the pointer ring, so we should examine the pointer type before freeing the pointer.

The first supported type is ubuf

Tun device looks similar to a packet socket in that both pass complete frames from/to userspace. This patch fills in enough fields in the socket underlying tun driver to support sendmsg/recvmsg operations, and message flags MSG_TRUNC and MSG_DONTWAIT, and exports access to this socket to modules. Regular read/write behaviour is unchanged. This way, code using raw sockets to inject packets into

Hi all: This series tries to implement rx batching for vhost-net. This is done by batching the dequeuing from skb_array which was exported by underlayer socket and pass the sbk back through msg_control to finish userspace copying. Tests shows at most 19% improvment on rx pps. Please review. Thanks Jason Wang (8): ptr_ring: introduce batch dequeuing skb_array: introduce batch dequeuing

Hi folks, I started testing the antispoof feature of xen stable (2.0.7). I am stuck with it. I have setup a standard bridged environment. I understood it like this: in domU config I set up the virtual NIC like vif = [ ''mac=ae:00:00:78:78:78, ip=192.168.0.100'' ] Then I configure /etc/network/interface of this domU to show the same IP address for eth0. After restarting

Hi, i have problems with the network between pv-domains and the real network. I done an upgrade with apt-get in debian an now i have xen4.1 with kernel 3.2.9 first i must chance the vif-bridge script from http://nopaste.php-q.net/194087 to http://nopaste.php-q.net/194084 now i have a connection from pv to dom0 and the windows hvm, but no connection between physical network an the pv

Hi all: This series tries to batch submitting packets to underlayer socket through msg_control during sendmsg(). This is done by: 1) Doing userspace copy inside vhost_net 2) Build XDP buff 3) Batch at most 64 (VHOST_NET_BATCH) XDP buffs and submit them once through msg_control during sendmsg(). 4) Underlayer sockets can use XDP buffs directly when XDP is enalbed, or build skb based on XDP

Hello, I use xen for a few months now and I upgraded to opensuse 10.3 with xen 3.1 (64bit versions) recently. Everything works fine, but there is a problem when I change xend-config.sxp to use my own network script (it''s slightly modified version of network-virtual scripts from http://en.opensuse.org/Xen3_yet_another_Virtual_Network_Concept ) instead of default network-bridge script.

Ok.. Just a little follow-up on my Solaris printing problem that I was having! As it turns out, I put the fully-qualified path names to the print commands (lpr/lpq/lprm, etc) in the samba config file (smb.conf) and all of my printing problems have disappeared! Now, after a clean reboot of the OS (Solaris, not PC), I can log on to Samba and directly print -- instead of it silently failing!

Hey, all. While ADA can still be downloaded, that's about all that I see. No development, no recent mention, and -- perhaps worst of all -- it appears not to work properly under 64-bit systems. So, assuming Digium's abandoned it, are there any suggestions of alternatives? Right now, I'm replacing a Shoretel system, and I'd *dearly* love to avoid the incredibly fat client they
