The reason is that htb considers a packet to be "sent" when it''s enqueued. I notice in retrospect that even with current SFQ, the statistics are not correct. The reason is that it''s possible to successfully enqueue packet#1 (at which point HTB adds its length to the number of bytes "sent)", then fail to enqueue packet#2. But within SFQ this "f...

From: Wei Wang <wei.w.wang at intel.com> A #GP is reported in the guest when requesting balloon inflation via virtio-balloon. The reason is that the virtio-balloon driver has removed the page from its internal page list (via balloon_page_pop), but balloon_page_enqueue_one also calls "list_del" to do the removal. This is necessary when it's used from balloon_page_enqueue_list, but not from balloon_page_enqueue. Move list_del to balloon_page_enqueue, and update comments accordingly.

I read the sched/qdiscs code from kernel source ... and I have some questions : When the .enqueue, .dequeue, .drop, .requeue functions are called ? What is the event that triggers them and how often this event apears ( per second ? ) ? When a qdisc is dequeued ( when it''s limit is reached ) ? Thanks _______________________________________________ LARTC mailing list / LARTC@mai...

...but I''ve a few questions about the mechanism. I dont'' think that I''d have any questions if I just wanted to know how to configure the Shaping method but I''m trying to get into the nuts and bolts. Basically I''m trying to find out the mechanism of the Enqueue and Dequeue operations. The utility tc which is used to configure the queues is external to the Kernel so it doesn''t configure the Kernel. I assume it just configures the tables that the Kernel uses. When the Kernel what''s to Queue something does it ask another process to do that...

...y traffic shaping to that interface, for example the outgoing traffic is shaped down to 1 MBit/s. There is an application that creates packets which are meant to be sent out via eth0, and the application creates its packets with a much higher rate than 1 MBit/s. This would result in the shaper enqueuing packets for eth0 and, sooner or later, in dropping some of the packets if the queue is full. So I want to slow down the rate at which the application creates its packets. The easiest way would be to take a look at the "traffic control" queues for eth0 and check their current state....

Hi, I''m adding a queuing disc. inside kernel. I am confused that it seems few other qdiscs allocate memory dynamically. Is it invalid to use memory calls like molloc or just a suggest that do not use it often? Thanks for your help. bon ----------------------------------------------------------------- < 每天都 Yahoo!奇摩 > www.yahoo.com.tw

...any user has a Ceil Rate they mustn''t trespass on. Being such a discipline non-work-conserving, I''ve to set a watchdog timer in order to allow further call of the dequeue function. However, I''ve noticed that such a solution prevents the local generated packets to be enqueued, which is very concerning to me being the priority based on the backlog... Does anyone know any trade-off solution between these needs (non-conserving-work and continuous enqueue flow)? Thanks in advance, Claudio.

From: "Michael S. Tsirkin" <mst.redhat.com> fill_balloon doing memory allocations under balloon_lock can cause a deadlock when leak_balloon is called from virtballoon_oom_notify and tries to take same lock. To fix, split page allocation and enqueue and do allocations outside the lock. Here's a detailed analysis of the deadlock by Tetsuo Handa: In leak_balloon(), mutex_lock(&vb->balloon_lock) is called in order to serialize against fill_balloon(). But in fill_balloon(), alloc_page(GFP_HIGHUSER[_MOVABLE] | __GFP_NOMEMALLOC | __GFP...
