__field(unsigned int, length):表示数据包长度。 __field(unsigned int, queue_mapping):表示用于标识数据包所属队列的索引。 __string(name, const char *):表示网络设备的名称。 通过这些信息,我们可以了解到每个进程发送的数据包大小、发送时使用的队列以及接收该数据包的网络设备。 收藏| 0点赞 | 0打赏...
That said, here's the proper page->pfmemalloc propagation onto socket: we must check the huge-page's head page only, other pages' pfmemalloc and mapping values do not contain what is expected in this place. However, I'm not sure whether this fix is _complete_, since pfmemalloc ...
But as soon as this skb is added to socket receive queue, another thread can consume it. This means that llc must use regular skb_unlink() and kfree_skb() so that both producer and consumer can safely work on the same skb. [1] BUG: KASAN: use-after-free in atomic_read include/...
The remaining fields, such as `queue_mapping`, `priority`, and `protocol`, are also initialized. The allocated `sk_buff` buffer can then be used by the network device driver to store incoming packets from the hardware device or to prepare outgoing packets for transmission. The driver can ...
System Interrupt Controller (SIC) The System Interrupt Controller provides the mapping and routing of events from the many peripheral interrupt sources to the prioritized general-purpose interrupt inputs of the CEC. Although the ADSP-BF561 provides a default mapping, the user can alter the mappings...
skb_set_queue_mapping(skb,queue_index); returnnetdev_get_tx_queue(dev,queue_index); } 如上所示,如果网络设备仅支持单个 TX 队列,则会跳过复杂的代码,直接返回单个 TX 队列。大多高端服务器上使用的设备都有多个 TX 队列。具有多个 TX 队列的设备有两种情况: ...
