Shared Libs on Linux: why does the dynamic linker run in user context? -

-

Reading I was strange (for my understanding) that the applications using shared libraries are loaded in two steps. <<>
"post-text" itemprop = "text">

Firstly Kernel loads the image of applications, then it adds the dynamic link-loader binary to the address space and gives control to it. The dynamic linkar loader runs in user space, it is believed that it is within the time frame of the application and pulls it into the rest of the code or links the context of the preloaded shared object. Was this idea (i.e. to restrict runtime consumption), why such a complex plan was chosen?

Why was such a complex plan chosen?

Because it is less complex than the option.

Specifically, it allows the development of GLIBC and Dynamic Loader without rebooting, allowing it to keep more than one version of the GLIBC loader simultaneously on the same system, and it will allow GLIBC to Stay together with other libc implementations (which will have their own dynamic loader)

Why should the kernel load the primary location in the first place? To remove

PT_INTERP , find and read the primary image I guess is to leave it in memory It was less work than to reload and work to translate the interpreter, and obviously it is too fast.

javascript - data.match(var) not working it seems -

OK, I have this small block code, which is to scanned a number on the website, but for some reason There is a hip that it is not scanning at all. var regenges = / \ & lt; Span class = "currency-robux" data-to-"item-private-value-price" & gt; ([\ D,]) \ & LT; \ / Span \ & gt; /; Var ValueCiling = Data. Match (reggae); Value-song = number (value slicing location (",", "")); Is there anything wrong with that? This is related to the if statement if (value sling and lieutenant; = price watching) { < P> A function calls to move from there, but for some reason it does not seem to run at all. So I think the Regex is wrong but I'm not sure how. (There is a variable in PriceWinking , this is a snippet from the code.) On the website, I'm trying to remove it. & lt; Span class = "robux" data-plus = "item-privatesale-price" & gt; 115 & lt; / Span & gt; Keep in mind
