The default glibc heap implementation in Linux is also very different to how the heap works in Windows. So for this and the next few posts, I’ll be focusing on the glibc heap allocator, i.e. how heap allocations work for C/C++ programs running on Linux devices by default. Arena: Arena is the top level memory management entity. There are two types of arenas. Main arena covers the traditional heap area: the space between start_brk and brk for a process from kernel point...To scalably handle memory allocation in multithreaded applications, glibc creates additional memory allocation arenas if mutex contention is detected. Each arena is a large region of memory that is internally allocated by the system (using brk (2) or mmap (2)), and managed with its own mutexes. accordance with usage in glibc 2.1. 3. 2000-02-28 Ulrich Drepper < [email protected] com > * stdlib / msort. c (qsort): Limit the amount of memory spend on a:

Aug 01, 2017 · The arena contained in the Glibc library is called main arena as it is used by the first/main thread. While an arena does not have a direct link to each memory region or to allocated chunks (see Fig. 1), there are other connections like pointers to freed chunks, the next arena and the top chunk.

It’s a nasty bug between the preallocation in glibc malloc() and the memory limit in rlimit. Any application that has a low rlimit (tens of gigabytes or less) is at risk to hit this bug and be terminated. How to mitigate? Preallocation behavior can be adjusted with the environment variable MALLOC_ARENA_MAX=4 int arena This is the total size of memory allocated with sbrk by malloc, in bytes. int ordblks This is the number of chunks not in use.

Recent versions of glibc ( from 2.12 ? ) have tunable MALLOC_ARENA_MAX and MALLOC_PER_THREAD. Arenas increases virtual memory usage : are suitable for 32 bit kernels ?
Debian has glibc 2.16 in the "experimental" repository, but recompiling the program is the safer option. Glibc is the library that everything depends on, so upgrading it can have far-reaching implications.

first of all the application memory footprint significantly increases. this would have been fine if this were the only issue. second, within an arena, glibc does not return memory to the kernel as you would expect. it request more memory when significant parts of the arena are free (and could be potentially be reusable/available).
前言你们去杭州打西湖论剑，我在宿舍捡题做，我们都有光明的未来。 分析这道题目还是很有意思的，有很多值得总结的地方。题目环境2.30，我在本地2.31的环境下完成。 首先程序标准的菜单堆，但是只能分配0x420-0x600之间的堆块，free未置NULL，有很明显的UAF。 但是还有一个相对隐蔽的漏洞，那就是 ... It is no longer available in current releases of glibc, and the new allocator became the default in 2.15 (I think). Setting MALLOC_ARENA_MAX=1 means there can only be one arena, which has a similar effect but is probably not strictly equivalent since other parts of the “new” allocator are still active in this case.

The tar pit of Red Hat overcomplexity RHEL 6 and RHEL 7 differences are no smaller than between SUSE and RHEL which essentially doubles workload of sysadmins who now need to administer an "extra" flavor of Linux/Unix. The main idea is to specify the head of the linked list in the arena, and then cheat GLIBC to malloc a new chunk at that speciﬁed place we prefer. But things are not very easy.The speciﬁed place(the fake chunk) must satisfy many conditions, otherwise malloc will go to failure.

If the arena uses malloc() internally, and do_work() does allocations through the arena, there's no need to free the entire arena in this case, despite it not being a static variable. While the user could always write static there, I'm not certain I agree it should be a requirement to do so.
