Programming :: Setup A Stack (1kB) For My Module In C?
Sep 6, 2010I need to call some other functions in "int init_module(void)" and module. So I need a stack. How can I setup a stack (1kB) for my module in C?

Programming :: Thread Stack Using Pthread_attr_setstackaddr()?
Sep 22, 2010When I set the stack base address of the child thread using the POSIX library function "pthread_attr_setstackaddr()", I am unable to access the memory contents of its parent. The data-structures that are created on the HEAP of its parent using malloc() are either getting destroyed or unaccessible when moving to the context of the child thread. These data-structures are being passed as an argument to the child thread.Even if I make these variables global then also it is not working.pthread_attr_setstacksize(tattr, ...);stackbase = (void *) malloc(...);pthread_attr_setstackaddr(tattr, stackbase);But when I create the child thread without setting its stack base address using that pthread_attr_setstackaddr(), then it is able to access the parent's memory contents.

May 1, 2011Why is it in Linux that there is a stack size set by default? And why is it so small? (My system is set to 8192 kbytes.) And why is there a default limit on the stack size when the max memory and virtual memory size are, by default, unlimited? (Aren't they both fed from the same place ultimately?)
Reason I ask: I want to use recursive functions in my programming a lot more. Problem is, if the language (or implementation) doesn't happen to support tail-call recursion, then I can be pretty well certain that the first huge problem that gets thrown at my function is going to kill my program because the stack size limit is going to be quickly reached. Obviously, I can change the stack size limit for my own computers, but it doesn't feel so great knowing that most of the people who copy and execute my code will have probably have overlooked this. Anyway, does anyone know: is this small default stack size limit just one of those historical artifacts, or is there some technical reason for it?

Jan 5, 2011Why the thread stack size can not be changed after calling pthread_attr_setstacksize & pthread_create in a dynamic library? Detail: I write a file thread_factory.c and plan to build it and produce a dynamic library (libthread_factory.so) In the thread_factory.c , there is a routine

And after this, there is application, it will call fct_thread_create(STACK_SIZE_256KB), and then call pthread_attr_getstacksize(), but the stack size return always be a fixed value 0xa01000. (I tried this on Fedora12) But if I build the application source code with the file thread_factory.c directly, the stack size return is right as my expect. I checked the source code of glibc about the routine pthread_create() as below:

Programming :: Rules To Set The Pthread Stack Size - Compute The Memory Needed By Each Thread?
Jul 26, 2010i have an application that launches several pthreads, i know that the default size used by Linux is 8Mb for each pthread. However i would like to optimize the total memory usage by my application by decreasing the default stack size of each pthread to the needed resources. My questions:
- Are there any rules to set the pthread stack size.
- How to compute the memory needed by each thread.
- Is the malloc call inside a thread counted from the stack size of the same pthread?

Looking at lsmod, it doesn't look like I have anything NAT related loaded ( I just have iptable_filter, ip_tables, and x_table ). Doing a locate nat, I find a module that looks like it should work.

Can that be done or the entire original sequential program must be rewritten?

Dec 8, 2013I'm trying to build the kernel module for dvbhdhomerun. The problem is the linux kernel headers provided by Debian do not have the dvb header files. Trying to set up my own kernel source tree to use is not working out so well.
I'm following the instructions in the Debian section here: [URL] ....
My first try compiled, but the modules ender up under /lib/modules/3.2.51/extra instead of /lib/modules/3.2.0-4-amd64/extra. Why?
I tried to start over, but noticed this while running apt-get source linux-image-3.2.0-4-amd64:
Code: Select allReading package lists... Done
Building dependency tree
Reading state information... Done
Picking 'linux' as source package instead of 'linux-image-3.2.0-4-amd64'
NOTICE: 'linux' packaging is maintained in the 'Svn' version control system at:
svn://svn.debian.org/svn/kernel/dists/trunk/linux/
[Code] ....
The failure to verify the signature has me concerned, but beyond that, what do I do about the different version number when compiling and installing the kernel modules?
