Since when kernelnewbies becomes the new
i created a kernel to kernel tcp socket
sent 4096 bytes from server ,
but in client on printing using %s it prints only 980 bytes
can anyone plz tell me why its happening?
Am i missing anything?
i have 2 completely different processes A and B (they do not have any
relationship)
suppose A opens a file with file descriptor 4 and
B opens another file with file descriptor 5
can process A use the fd 5 (i.e using the file object of processs B) by any
means..
if suppose i let the fd 4 of
even if process A does recv the file descriptions thru sockets how will it
use the file object of process B?

then proc B does a dup2(5,4) sys call .//dup2(oldfd,newfd)
so would proc A be reading/writing the contents of fd=5(file opened by proc
B) when it does a read/write on fd=4(file opened by proc A)?

Dear all,
I wonder if anyone could provide the example for the usage of copy_from_usr
and copy_to_usr including the programs both in kernel space and in user
space.
how to define the memory or buffer where the data is communicated.
thanks very much,

hello
i am a newbie, i know about exporting variables between modules,
but what i am trying right now is to export a structure( i want to make a
global structure)
i wrote this in one module.
Code:
struct abc{
int y;
int a[10];
int *z[10];
};
struct abc *x;
EXPORT_SYMBOL(x);
then i tried to
can sumone plz give me a complete list of the system calls(according to
linux kernel 2.6.18 or above) that makes disk access at some point of time.
For eg. read sys call makes a disk access when it doesnt find the page in
page cache.

i tried to printf the return values of error codes but that wont work bcoz
the elf does run successfully(no errors)
As execve doesnt return anything on a successful execve sys call,is there a
way to check whether it was successful or not.
neglect the fact that i can see the elf running
it.
is there any other way to do so?

i used 2.6.11 and found codes written fro pentium 32 bit architecture in
i386, but now i moved to 2.6.28 but thr is no i386 folder in arch dir..
*so can u tell me which is the i386 equivalent directory in arch dir of
2.6.28? *
can sumone plz tell me in detail or gimme any reference for how to create
our own system calls ?
i want to write my own new system call.
im new to linux
can sumone plzz tell me* how to call a function defined in one module frm
