Linux内核中libc.so.6的相关性 [英] Relevance of libc.so.6 in Linux kernel

问题描述

我的问题是Linux内核是否包含libc.so.6?仔细研究并浏览不同的链接后，我们发现libc.so.6不是Linux内核的一部分，因为内核具有相同的库，供内核空间使用. libc.so.6是一个用户空间库.但是，仍然有一个问题，如果从"/lib"中删除了libc.so.6，它将崩溃，因为Linux的所有基本应用程序都崩溃了.

My question is whether Linux kernel contains libc.so.6? After googling and going through different links, we found that libc.so.6, is not a part of Linux kernel, as the kernel has same libraries implemented for its own use in kernel space. libc.so.6 is a userspace library. But, still, the question was left, if the libc.so.6 is removed from "/lib", it crashes, as all the basic applications of Linux crashes.

因此，剩下的基本问题是:

So, the basic questions were left on:

1. Linux是否可以在没有libc.so.6的情况下运行?如果是，那么在哪里使用这种实现?
2. 谁提供libc.so.6?它仅由Linux发行版提供吗?
3. Linux内部是否支持线程化?

1. Can Linux run without libc.so.6? If yes, where such implementation is used?
2. Who provides libc.so.6? Is it provided by Linux distributions only?
3. Does Linux internally supports threading or not?

推荐答案

1. 是的.例如，我可以在不使用libc的程序集中编写一个应用程序.以下是一些示例: https://stackoverflow.com/questions/284797/hello少于20个字节的世界
2. 在Linux上，glibc是libc的常见实现: https://www.gnu.org /software/libc/
3. 是的. glibc提供的线程选项是内核接口上的垫片层.

1. Yes. For example, I could write an application in assembly that did not use libc. Here are some examples: https://stackoverflow.com/questions/284797/hello-world-in-less-than-20-bytes
2. On Linux, glibc is a common implementation of libc: https://www.gnu.org/software/libc/
3. Yes. The threading options that glibc provides are a shim layer over a kernel interface.
