发帖数: 72 | 3 finally sick of getting tens of spam
everyday. their email address should be faked?
because I tried replying to them
and always bounced back.
So is it possible to block those emails?
I know somebody has a program to do so.
basically check how much the file is and
if it too large, the email will be returned.
guess I want a program that can check the email
title or address, and then decide to bounce back
their emails. |

发帖数: 1119 | 7 不像 windows, 32bit memory limit 对 Linux 没有太大的影响。
Linux 下的 32bit memory limit 是 4G Virtual address space per process, low
memory 840M reserved for kernel, PTE etc. 实际的 physical memory 可以扩展到
64GB depending on hardware platform.
所以在 Linux 下，32 bit 唯一的问题就是 process 不能一口咬 大于 4G 的 memory
, 但也有 workaround. |

别人回答这个了，我同意 ：-）
说的对啊。
关键是我觉得你不熟悉 process virtual memory mapping 这个概念。
在 linux 里面， /proc//maps
就说明这个 process 的 virtual memory 是如何 map 的。
你可以看到当前的 [heap] 在什么 virtual address range.
brk 可以调整那个 [heap] 的结束地址。
里面还有 [stack] 是 stack 的 virtual address. |

这个都对。
这个不对。这个表明你还没有理解 kernel 的 virtual memory 是如何工作的。
没有用上的 virtual address 是 page table 是空的。你如果访问
就直接 signal 11 segfault. 这个 virtual address 有没有用上是
vma 那层管理的。 每个 process 有自己 vma list.
kernel 可以 swap 几乎任何 heap 甚至 mmap 里面的内存页。kernel 把
那个页里的内容写到 file backing 里面就可以把那个 page 偷走了。
被偷的 vma 里面换成 empty page, 访问的时候产生 page fault.
在 page fault handler 里面把那个页的原来内容再从文件里恢复
出来。这个就是 swapping. 恢复的那个 physical page 完全可能和
原来上一次的 physical page 不是同一个。只是内容一样。对 process
来说是透明的。 |

发信站: BBS 未名空间站 (Sat Dec 18 18:40:01 2010, 美东)
在Linux下，一个process运行的时候address space都会有stack section, data
section, test section, bss section,等等，以及由 malloc()所得到的 memory.
我的问题是，malloc()到底是从系统的什么地方得到的动态memory?是不是从所谓的
heap 得到的?
如果是这样，是不是 heap 就是整个系统共有的 memory pool,各个process可以从这里
动态的得到memory via malloc()?
谢谢！ |
