Namespace là một tính năng của Linux kernel để phân vùng tài nguyên của kernel sao cho một tập hợp các process chỉ nhìn thấy tập hợp các tài nguyên (trong namespace đó) trong khi một tập hợp các process khác nhìn thấy tập các tài nguyên khác (trong namespace khác). Tính năng này hoạt động bằng cách đưa tập các tài nguyên và process vào cùng một namespace, các namespace khác nhau sẽ tham chiếu đến các tài nguyên riêng biệt.

 - An IRQ (Interrupt Request) is a hardware signal sent to the processor instructing it to suspend its current activity and handle some external event, such as a keyboard input or a mouse movement.
 - In Linux, IRQ mappings are stored in **/proc/interrupts**.
 - When an IRQ handler is executed by the Linux kernel, it runs at a very, very high priority and often blocks additional IRQs from being generated. As such, IRQ handlers in device drivers must execute as quickly as possible and defer all long running work to execute outside of this context. This is why the **softIRQ** system exists.
-- **softIRQ** system is a system that kernel uses to process work outside of the device driver IRQ context. In the case of network devices, the softIRQQ system is responsible for processing incoming packets<ul><li><p>Initial setup (from step 1-4):</p><p><img src=https://cdn.buttercms.com/hwT5dgTatRdfG7UshrAF alt></p><ul><li>softIRQ kernel threads are created (1 per CPU).</li><li>The ksoftirqd threads begin executing their processing loops.</li><li><code>softnet_data</code> structures are created (1 per CPU), hold references to important data for processing network data. <code>poll_list</code> is created (1 per CPU).</li><li><code>net_dev_init</code> then registers the <code>NET_RX_SOFTIRQ</code> softirq with the softirq system by calling <code>open_softirq</code> - this registration is called <code>net_rx_action</code>,</li></ul></li><li><p>Alright, Linux just init and setup networking stack to wait for data arrival:</p><p><img src=https://cdn.buttercms.com/yharphBYTEm2Kt4G2fT9 alt></p><ul><li>Data is received by the NIC (Network Interface Card) from the network.</li><li>The NIC uses DMA (Direct Memory Access) to write the network data to RAM (in ring buffer).<ul><li>Some NICs are &ldquo;multiqueue&rdquo;

If they take too long to execute, they will cause the CPU to be unable to respond to other HardIRQ, so the kernel introduces <code>SoftIRQs</code> (Soft Interrupts), so that the time-consuming part of the HardIRQ handler can be moved to the SoftIRQ handler to handle it slowly. We will talk about SoftIRQ in the next steps.</li><li>HardIRQs can be seen in <code>/proc/interrupts</code> where each queue has an interrupt vector in the 1st column assigned to it. These are initialized when the system boots or when the NIC device driver module is loaded. Each RX and TX queue is assigned a unique vector, which informs the interrupt handler as to which NIC/queue the interrupt is coming from.

Let&rsquo;s talk about the RX ring buffer:</p><ul><li>It is a <a href=https://en.wikipedia.org/wiki/Circular_buffer>circular buffer</a> where <em>an overflow simply overwrites existing data</em>.</li><li>It <em>does not contain packet data</em>.

The NIC notifies the kernel of this data by raising a HardIRQ. These interrupts are processed by interrupt handlers which do minimal work, as they have already interrupted another task and cannot be interrupted themselves.</li><li>HardIRQs can be expensive in terms of CPU usage, especially when holding kernel locks. If they take too long to execute, they will cause the CPU to be unable to respond to other HardIRQ, so the kernel introduces <code>SoftIRQs</code> (Soft Interrupts), so that the time-consuming part of the HardIRQ handler can be moved to the SoftIRQ handler to handle it slowly. We will talk about SoftIRQ in the next steps.</li><li>HardIRQs can be seen in <code>/proc/interrupts</code> where each queue has an interrupt vector in the 1st column assigned to it. These are initialized when the system boots or when the NIC device driver module is loaded. Each RX and TX queue is assigned a unique vector, which informs the interrupt handler as to which NIC/queue the interrupt is coming from. The columns represent the number of incoming interrupts as a counter value:</li></ul><div class=highlight><pre tabindex=0 class=chroma><code class=language-shell data-lang=shell><span class=line><span class=cl>egrep “CPU0<span class=p>|</span>eth3” /proc/interrupts

Being in software, it is necesarily called later in the datapath. Whereas RSS selects the queue and hence CPU that will run the hardware interrupt handler, RPS selects the CPU to perform protocol processing above the interrupt handler.</li><li>When the driver receives a packet, it wraps the packet in a socket buffer <code>sk_buff</code> which contains a <code>u32</code> hash value for the packet (based on source IP, source port, dest IP, dest port). Since every packet of the same TCP/UDP connection (flow) shares the same hash, it&rsquo;s reasonable to process them with the same CPU. After that, it will reach either <code>netif_rx_internal()</code> or <code>netif_receive_skb_internal()</code>, and then <code>get_rps_cpu()</code> will be invoked to map the hash to an entry in <code>rps_map</code>, i.e. the CPU id. After getting the CPU id, <code>enqueue_to_backlog()</code> puts the sk_buff to the specific CPU queue for the further processing. The queues for each CPU are allocated in the per-cpu variable, <a href=https://github.com/torvalds/linux/blob/v4.11/include/linux/netdevice.h#L2788><code>softnet_data</code></a>.</li></ul><p><img src=https://3.bp.blogspot.com/-zRdZ1Bw1frw/WUNdJCURkvI/AAAAAAAAA-Q/XgYiaHsBsNc9cWwAdZu83HhfOUtuSTCkgCLcBGAs/s640/RPS.png alt></p><ul><li>The benefit of using RPS is same as RSS: share the load of packet processing among the CPUs.<ul><li>It may be unnecessary if RSS is availble.</li><li>If there are more CPUs than the queues, RPS could still be useful.</li></ul></li><li>RPS requires a kernel compiled with the <code>CONFIG_RPS</code> kconfig symbol (on by default for SMP).

In other words, a processor can access local memory much faster than non-local memory. This is because in a NUMA setup, each processor is assigned a specific local memory exclusively for its own use. This elimates sharing of non-local memory, reducing delays (fewer memory locks) when multiple requests come in for access to the same memory location -> Increase nework performance (cause CPUs have to access ring buffer (memory) to process data packet)</li></ul><p><img src="https://b2600047.smushcdn.com/2600047/wp-content/uploads/2018/04/NUMA-Architecture.png?lossy=1&amp;strip=1&amp;webp=1" alt></p><ul><li>NUMA architecture splits a subset of CPU, memory, and devices into different &ldquo;nodes&rdquo;, in effect creating multiple small computers with a fast interconnect and common operating system.

 </span></span></code></pre></div><p>I&rsquo;ve founded out about Recurse Center, formerly known as Hacker School, from <a href=https://jvns.ca/blog/2017/09/17/how-i-spent-my-time-at-the-recurse-center/>Julia Evan&rsquo;s blog</a>.</p><p>Recurse Center is a independent, community-driven learning and software development retreat located in New York City, United States. Recurse Center focuses on providing a free and open learning environment for programmers, aiming to create a platform where they can explore, develop, and interact with each other. You will spnd six or 12 weeks programming at the edge of your abilities alongside motivated peers - at no cost to you.</p><p>Recurse Center is not a traditional school but a <a href=https://www.recurse.com/self-directives>self-directives</a> learning community:</p><ul><li><strong>Work at the edge of your abilities</strong> means being ambitious about what you can achieve and also honest about your capacity, choosing work that challenges you but isn’t so far beyond your current abilities that it’s discouraging.</li></ul><blockquote class=twitter-tweet><p lang=en dir=ltr>I often advise people to take on projects you're only 70% qualified for, but then learn like crazy to bridge that 30%.</p>&mdash; Andrew Ng (@AndrewYNg) <a href="https://twitter.com/AndrewYNg/status/841076327931236352?ref_src=twsrc%5Etfw">March 12, 2017</a></blockquote><script async src=https://platform.twitter.com/widgets.js></script><ul><li><strong>Build your volitional muscles</strong> means growing your ability to make decisions about your work and learning based your own curiosity and joy, rather than external pressures and fears.</li><li><strong>Learn generously</strong>.</li></ul><p>Recurse Center does not have any prerequisites and welcomes programmers of all skill levels. Their learning program doesn&rsquo;t involve teachers, lectures, or predefined curriculum. Instead, members actively build and manage their learning journey based on their interests and personal goals.</p><p>In addition to individual learning, Recurse Center organizes extended activities and community events such as discussions, internships, and group meetings. These initiatives help foster social connections and expand the network of programmers within the community.</p><p>Recurse Center has become a sought-after destination for individuals looking to enhance their programming skills, cultivate creativity, and tackle new challenges in the field of technology.</p><p>One more thing, Recurse Center has a small set of lightweight <a href=https://www.recurse.com/social-rules>social rules</a> that make more <em>explicit</em> certain social norms that are normally <em>implicit</em>. And I found these rules are not only applicable at Recurse Center but should also be applied to life and corporate culture. People may unintentionally be a jerk somewhat, read through the following and ask yourself.</p><ul><li><strong>No feigning surprise</strong>: You shouldn&rsquo;t act surprised when people say they don&rsquo;t know something. This applies to both technical things (&ldquo;What?!

 Docker network Let&amp;rsquo;s start with a fact that Docker manipulates iptables rules to provide network isolation, on Linux. Docker installs custom iptables chains named DOCKER, DOCKER-USER and DOCKER-ISOLATION-STAGE-*, and it ensures that incoming packets are always checked by these chains first.
 iptables -L -n Re.Docker network, I won&amp;rsquo;t describe here because it&amp;rsquo;s a lot of knowledge.</description></item></channel></rss>
