Ubuntu 17.10上使用crosstool-ng-1.23.0建立WD MyCloud修复工具编译环境(uClibc)

参考更优雅的(不拆硬盘)拯救死翘翘了的WD MyCloud(Ubuntu 17.10)编译出来的Busybox是只有3MB大小的样子，这样编译出来的东西非常基础，功能有限。如果想要增加其他软件的时候，最少改动的情况下，一般都依赖GLIBC,而GLIBC完整编译出来的库接近50MB，而我们修复系统，是一个纯内存文件系统。直接采用GLIBC会非常浪费不多的内存空间。

因此在低内存的系统上采用uClibc，变成一个不错的选择。下面我们讲一下如何通过crosstool-ng-1.23.0构建一个我们需要的编译系统出来。

首先编译crosstool-ng-1.23.0源代码

$ sudo apt-get update
$ sudo apt-get upgrade

$ sudo apt-get -y install autoconf
$ sudo apt-get -y install gperf
$ sudo apt-get -y install bison
$ sudo apt-get -y install flex
$ sudo apt-get -y install texinfo
$ sudo apt-get -y install help2man
$ sudo apt-get -y install ncurses-dev

$ cd ~

$ git clone https://github.com/crosstool-ng/crosstool-ng

$ cd crosstool-ng

$ ./bootstrap

$ ./configure --prefix=`echo ~`/wd_crosstool

$ make

$ make install

$ sudo apt-get update

$ sudo apt-get upgrade

$ sudo apt-get -y install autoconf

$ sudo apt-get -y install gperf

$ sudo apt-get -y install bison

$ sudo apt-get -y install flex

$ sudo apt-get -y install texinfo

$ sudo apt-get -y install help2man

$ sudo apt-get -y install ncurses-dev

$ cd ~

$ git clone https://github.com/crosstool-ng/crosstool-ng

$ cd crosstool-ng

$ ./bootstrap

$ ./configure --prefix=`echo ~`/wd_crosstool

$ make

$ make install

如果下载crosstool-ng源代码存在问题，可以从本站下载一份代码拷贝。点击此处下载。

$ cd ~

$ mkdir wd_fix_toolchain

$ cd wd_fix_toolchain

$ export PATH=~/wd_crosstool/bin/:$PATH

$ cp ~/crosstool-ng/samples/arm-unknown-linux-uclibcgnueabihf/crosstool.config .config

$ ct-ng oldconfig

#默认一路回车,只是注意，中间选择Linux内核版本的使用，选择使用Linux 3.2 CT_LINUX_V_3_2=y

$ ct-ng build

$ cd ~

$ mkdir wd_fix_toolchain

$ cd wd_fix_toolchain

$ export PATH=~/wd_crosstool/bin/:$PATH

$ cp ~/crosstool-ng/samples/arm-unknown-linux-uclibcgnueabihf/crosstool.config .config

$ ct-ng oldconfig

#默认一路回车,只是注意，中间选择Linux内核版本的使用，选择使用Linux 3.2 CT_LINUX_V_3_2=y

$ ct-ng build

最终的.config文件，可以参考下面的配置信息，或者简单的拷贝这个文件到编译目录即可

PTP简介

在通信网络中，许多业务的正常运行都要求网络时钟同步，即整个网络各设备之间的时间或频率差保持在合理的误差水平内。网络时钟同步包括以下两个概念：

时间同步：也叫相位同步（Phase synchronization），是指信号之间的频率和相位都保持一致，即信号之间的相位差恒为零。

频率同步（Frequency synchronization）：也叫时钟同步，是指信号之间在频率或相位上保持某种严格的特定关系，信号在其对应的有效瞬间以同一平均速率出现，以保证通信网络中的所有设备都以相同的速率运行，即信号之间保持恒定的相位差。

继续阅读PTP简介

网络时钟同步协议-- NTP, PTP

这篇文章介绍一下两个时钟同步的网络协议：NTP和PTP。
这里不涉及协议的原理和具体实现(想了解的可自行Google)，重点是如何搭建起这两个服务。

1. NTP及PTP简介

NTP(Network Time Protocol)是用于不同计算机之间同步时钟的网络协议。
它的设计目标是使所有的互连的机器之间的时钟与UTC时间只相差若干毫秒。

目前NTP协议已经是有第4版了，如果不需要了解NTP太多细节的话，看看这个wiki页面应该就足够了。需要注意的就是它有clock strata的概念。

PTP(Precision Time Protocol)看名字就知道是一个比NTP更精确的时钟同步协议了，PTP的设计目标是使机器之间的时钟偏差在sub-microsecond范围—这是wiki页面上提到的，有其他的地方说的是偏差若干微秒，本文搭建的环境中测量到的偏差也在微秒级别，没有到sub-microsecond级别。在使用PTP协议时，需要了解的主要概念点就是它的master/slave机制。

接下来我们就介绍我搭建NTP和PTP环境的过程，所用到的操作系统是CentOS6.5，内核版本是3.10。其他软件的版本会在用到时提及。

2. 搭建NTP服务

配置环境：两台服务器，一台做NTP服务器，一台做NTP的客户端。同时这两台机器都未联网。
NTP服务器地址：192.168.0.11
NTP客户端地址：192.168.0.22

A. 在192.168.0.11中启动NTP服务

$ service iptables stop  // 首先把防火墙关了  
$ yum list |grep ntp     // 看下yum源中是否有ntp软件    
$ yum install -y ntp    
$ ntpd --version  
    ntpd 4.2.6p5  
$ vim /etc/ntp.conf      // 修改配置文件  
    restrict 192.168.0.11 mask 255.255.255.0 nomodify nostrap  // 限制作为局域网NTP服务器
    // 下面两句很关键。含义是如果这台NTP服务器的server地址无法访问，  
    // 则将本地时间作为NTP服务时间，这个IP地址也是固定的，不要修改  
    server 127.127.1.0  
    fudge  127.127.1.0 stratum 10   
$ ntpd -p /var/run/ntpd.pid  // 启动ntpd  
$ service ntpd start          // 第二种启动ntpd服务的方法  
// 等待5分钟  
$ ntpstat // 从这条命令应该能看到NTP时钟同步好了，正常的显示结果应该与下面类似  
    synchronised to local net at stratum 11
        time correct to within 11 ms  
        polling server every 64 s

$ service iptables stop // 首先把防火墙关了

$ yum list |grep ntp // 看下yum源中是否有ntp软件

$ yum install -y ntp

$ ntpd --version

ntpd 4.2.6p5

$ vim /etc/ntp.conf // 修改配置文件

restrict 192.168.0.11 mask 255.255.255.0 nomodify nostrap // 限制作为局域网NTP服务器

// 下面两句很关键。含义是如果这台NTP服务器的server地址无法访问，

// 则将本地时间作为NTP服务时间，这个IP地址也是固定的，不要修改

server 127.127.1.0

fudge 127.127.1.0 stratum 10

$ ntpd -p /var/run/ntpd.pid // 启动ntpd

$ service ntpd start // 第二种启动ntpd服务的方法

// 等待5分钟

$ ntpstat // 从这条命令应该能看到NTP时钟同步好了，正常的显示结果应该与下面类似

synchronised to local net at stratum 11

time correct to within 11 ms

polling server every 64 s

B. 在192.168.0.22上启动NTP服务，选择192.168.0.11为NTP服务器

$ service iptables stop
$ yum install -y ntp
$ vim /etc/ntp.conf  // 添加下面这个server地址，把其他的都注释掉  
    server 192.168.0.11  
$ service ntpd start
$ netstat  // 等待若干时间应该就能够显示同步成功了

$ service iptables stop

$ yum install -y ntp

$ vim /etc/ntp.conf // 添加下面这个server地址，把其他的都注释掉

server 192.168.0.11

$ service ntpd start

$ netstat // 等待若干时间应该就能够显示同步成功了

我的这两台实验机器是在同一个Rack的，结果显示差不多同步的偏差在30ms左右。
每个版本的ntpd配置文件可能有少许的差别，不过好在注释都做的不错，所以别的细节就不啰嗦了。

3. 搭建PTP服务

从List of PTP implementations可以看到PTP的实现有很多很多种，可以是硬件实现的，可以是软件实现的也可以是软硬件结合实现的。本文中搭建的PTP服务是基于软件PTPd。如果没有特殊的硬件的话，这算是一种非常方便的方法了。

$ service iptables stop // 关掉防火墙  
$ yum list |grep ptp    // 检查yum源  
$ yum install -y ptpd
$ ptpd2 --version  
    ptpd2 version 2.3.0  
// 弄一个管理脚本，从serverfault找来的 ：）    
// http://serverfault.com/questions/329127/ptp-time-synchronization-on-centos6-rhel
$ vim ptpd.sh  // 将PTPADRGS 改为 PTPD_EXTRA_OPTIONS  
$ chmod +x ptpd.sh 
$ vim /etc/ptpd2.conf  // 修改配置文件  
    ptpengine:preset=masterslave    // 对于master主机，不要选masteronly，具体原因请查看help  
    ptpengine:preset=slaveonly      // 对于slave主机  
    // 其他选项也可以根据需要进行调整，比如log是否开启，是否绑定CPU。这些看配置文件的注释就好了  
$ vim /etc/sysconfig/ptpd2  // 修改启动命令，主要就是指定PTPD的配置文件  
    PTPD_EXTRA_OPTIONS="-c /etc/ptpd2.conf"  
// 现在就可以使用下面三个命令来启动，查看和关闭ptpd服务了  
$ ./ptpd.sh start  
$ ./ptpd.sh status  
$ ./ptpd.sh stop

$ service iptables stop // 关掉防火墙

$ yum list |grep ptp // 检查yum源

$ yum install -y ptpd

$ ptpd2 --version

ptpd2 version 2.3.0

// 弄一个管理脚本，从serverfault找来的：）

// http://serverfault.com/questions/329127/ptp-time-synchronization-on-centos6-rhel

$ vim ptpd.sh // 将PTPADRGS 改为 PTPD_EXTRA_OPTIONS

$ chmod +x ptpd.sh

$ vim /etc/ptpd2.conf // 修改配置文件

ptpengine:preset=masterslave // 对于master主机，不要选masteronly，具体原因请查看help

ptpengine:preset=slaveonly // 对于slave主机

// 其他选项也可以根据需要进行调整，比如log是否开启，是否绑定CPU。这些看配置文件的注释就好了

$ vim /etc/sysconfig/ptpd2 // 修改启动命令，主要就是指定PTPD的配置文件

PTPD_EXTRA_OPTIONS="-c /etc/ptpd2.conf"

// 现在就可以使用下面三个命令来启动，查看和关闭ptpd服务了

$ ./ptpd.sh start

$ ./ptpd.sh status

$ ./ptpd.sh stop

如果遇到任何问题，首先一定要看看help，使用-H选项的话还能看到非常详细的配置（虽然大多我可看不懂，不过不能不看，理解的越多，遇到的问题就会越少）。
如果log里面的信息看不懂，可以把代码下下来，一个grep搞定。

经测试，在我的机器上使用PTPD软件搭建的服务，时钟偏移的平均值能够达到5us左右。这个粒度基本能满足我们的需求了。

Linux中的时钟准确度

本文来自戴尔软件开发高级工程师Stuart Hayes

一个关于计时的问题最近引起了我的关注。有用户在 Dell 服务器上运行 Linux，并且发现时钟时间（Linux 所报告的）每天误差五秒以上，偏差比较明显。

我们首先想到的也许是运行 NTP，定期与真实世界同步操作系统的时钟。

但是这样的误差最初是如何产生的？

在Linux运行时，Linux 系统未使用实时时钟(real time clock - RTC) 硬件来计时。 Linux 通常在启动时从RTC 读取时间，然后从该点开始，Linux 使用另一个时钟来源（系统中的另一个计时器/计数器）来计时。

自第 2.6.18 版起，Linux 的内核就使用 CPU 时间戳计数器 (TSC) 作为首选的时钟来源（假设 TSC 以恒定频率运行，以新款的 Intel 服务器 CPU为例）。但是，尽管读取速度很快且解析度很高，TSC 却不是一个已知的频率。当内核使启动时，它需要使用频率已知的另一个计时器，对其进行校准。这样的校准并非天衣无缝（即使用于校准的计时器也是如此），因此把 TSC 作为时钟来源会造成时间误差。

如果减少时间误差对您非常重要，而非若干微秒的调度延迟，则最好使用频率已知的计时器，如大多数 x86 服务器上提供的 HPET（高精度事件计时器）。借助新内核上的参数"clocksource=hpet"可实现这一目标。 HPET 计时器以已知、固定的频率运行，Linux 内核可直接从计时器读取时间。

话说回来，尽管 HPET 的精度高于 TSC，运行 NTP 以在 Linux 中实现长期的时钟精度始终是很好的想法。
上述讨论仅适用于运行于裸机的 Linux。在虚拟机中的问题略微复杂。

Linux 中的时钟准确度

Linux时钟精度：毫秒？微妙？纳秒？

最近被内核时钟精度弄的很是郁闷。具体情况如下：

扫盲：1秒=1000毫秒=1000000微妙=1000000000纳秒

首先：linux有一个很重要的概念——节拍，它的单位是（次/秒）。2.6内核这个值是1000，系统中用一个HZ的宏表征这个值。同时有全局的jiffies变量，表征从开机以来经过的节拍次数（这里面还有故事，后面说，先记住这个）。当然还有wall_jiffies的墙上jiffies来表示从 07-01-1970 到现在的节拍数。每个节拍里面执行一次时钟中断。就是说，它的精度是毫秒。

接着：内核中还有一个变量xtime表征系统的实际时间（墙上时间），定义如下。其中xtime.tv_sec以秒为单位，存放从Unix祖宗定的纪元时间（19700701）到现在的秒数。xtime.tv_nsec以纳秒为单位，记录从上一秒开始经过的纳秒数。就是说，它的精度是纳秒。

struct timespec xtime;

struct timespec{
    time_t tv_sec;   //秒
    long tv_nsec;    //纳秒
};

struct timespec xtime;

struct timespec{

time_t tv_sec; //秒

long tv_nsec; //纳秒

};

最后：linux提供一个gettimeofday的系统调用，它会返回一个timeval的结构体，定义如下。解释同上，tv_sec代表墙上时间的秒，tv_usec表示从上一秒到现在经过的微秒数。就是说，它的精度是微妙。

struct timeval{
    long tv_sec;     //秒
    long tv_usec;    //微妙
};

struct timeval{

long tv_sec; //秒

long tv_usec; //微妙

};

精彩的来了：
1. 内核中的xtime会在每个时钟中断的时候被更新一次，也就是每个节拍更新一次。你妹！！每毫秒更新一次怎么能冒出来纳秒的精度？？而且，内核还有可能丢失节拍。怎么能是纳秒？？
2. 各种书上说，gettimeofday系统调用是读取的xtime的值。日，为啥读出来之后精度丢了？变成微妙了？

寻寻觅觅终于理清了故事：
针对问题1：在linux启动的时候，一个节拍的时间长度还会以纳秒为单位初始化到tick_nsec中，初始化值为999848ns，坑爹啊！不到一毫秒！节拍大约为1000.15Hz。靠！实际的节拍竟然不是准确的1000！所以在每个时钟中断通过wall_jiffies去更新xtime的时候得到的就是一个以纳秒为最小单位的的值。所以！xtime的粒度应该是不到1毫秒，也就是精度是不到1毫秒。

针对问题2：gettimeday系统调用的读xtime代码部分如下：

do{
    unsigned long lost;
    seq = read_seqbegin(&xtime_lock);

    usec = timer->get_offset();    //在计时器中取从上一次时钟中断到现在的微秒数
    lost = jiffies - wall_jiffies;
    if(lost)
        usec += lost*(1000000/HZ); //HZ是节拍宏，值1000
    sec = xtime.tv_sec;
    usec += (xtime.tv_nsec/1000);  //由纳秒转为微妙

}while(read_seqretry(&xtime_lock, seq))

do{

unsigned long lost;

seq = read_seqbegin(&xtime_lock);

usec = timer->get_offset(); //在计时器中取从上一次时钟中断到现在的微秒数

lost = jiffies - wall_jiffies;

if(lost)

usec += lost*(1000000/HZ); //HZ是节拍宏，值1000

sec = xtime.tv_sec;

usec += (xtime.tv_nsec/1000); //由纳秒转为微妙

}while(read_seqretry(&xtime_lock, seq))

while部分使用了seg锁，只看中间的就好了。加了注释之后就很清晰了。由于节拍可能会丢失，所以lost是丢失的节拍数（不会很多）。至于计时器就比较麻烦了，timer可能有下面四种情况。

a. 如果cur_timer指向timer_hpet对象，该方法使用HPET定时器——Inter与Microsoft开发的高精度定时器频率至少10MHz，也就是说此时可提供真正的微妙级精度。
b. 如果cur_timer指向timer_pmtmr对象，该方法使用ACPI PMT计时器（电源管理定时器）平率大约3.58MHz，也就是说也可以提供真正的微妙级精度。
c. 如果cur_timer指向timer_tsc对象，该方法使用时间戳计数器，内置在所有8086处理器，每个CPU时钟，计数器增加一次，频率就是CPU频率，所以timer精度最高。完全可以胜任微妙级的精度。
d. 如果cur_timer指向timer_pit对象，该方法使用PIT计数器，也即是最开始提到的节拍计数，频率大概是1000Hz，此时显然不能提供精度达到微妙的时间。所以只有这种情况是假毫秒精度！

综上：如果使用gettimeofday系统调用，只要不要使用节拍计数器就可以保证达到微妙精度的时间（刨除进程上下文时间误差）。至于网上说的可以拿到纳秒精度的时间，看起来都是错的。除非通过修改内核，使用时间戳计数器实现。Over！

最后最后说一个事情：jiffies的定义的是4字节，你可能猜想它初始值是0。实际上，事实并非如此！linux中jiffies被初始化为0xfffb6c20,它是一个32位有符号数，正好等于-300 000。因此，计数器会在系统启动5分钟内溢出。这是为了使对jiffies溢出处理有缺陷的内核代码在开发阶段被发现，避免此类问题出现在稳定版本中。

更优雅的(不拆硬盘)拯救死翘翘了的WD MyCloud(Ubuntu 17.10)

以前WD MyCloud被捣鼓坏掉了，都是参考拯救死翘翘了的 WD MyCloud来处理的，但是这种处理方式需要拆机，非常的费力。最近看到有人发布了可以不拆机的方式修复的方法。研究了一下，非常可行，推荐使用这种方法。

下面的这些操作都是WD论坛上的一些达人通过分析WD MyCloud的源代码得到的，没有非公开的黑科技，都是一些明确公布的内容。

原理大致讲一下，在WD MyCloud主板上有一块Flash闪存，闪存里面是已经写入的barebox。WD MyCloud启动的时候会把barebox从闪存载入到内存中，并且启动barebox，而barebox启动后，会等待5S的时间，检测是否有人向自己的网卡发送内容为WD-ICMP-BEACONWD-ICMP-BEACONWD-ICMP-BEACONWD-ICMP-的ICMP报文(本质就是PING)，一旦检测到这个报文，就会连接这个报文的发送方的69号端口（TFTP服务器端口），获取一个名为startup.sh的脚本，并且下载完成后，执行这个脚本。因此我们就可以在这个脚本中拉取一个自己编译好的内核，然后运行这个内核，达到修改系统的目的。
