Hi All,
I wanted to know how a packet received will be handovered to a correct user
process.
Basically I want to understand what are the various header parameters in
packet which will help to find the open socket descriptor of respective
user process. I'm not able to find the exact answers in t

Hello all ,
Could some body please suggest any books/links for Linux networking
protocol development.
Protocol development at L2/L3 layers.
Thanks in advance.

Hi all,
I'm probing sys_write system call using system tap to get modified file
name along with UID.
Here is code snippet.
probe kernel.function ("vfs_write")
{
filename = user_string($file->f_dentry->d_name->name) // for
2.6.18 kernel.
printf ("%d %s\n",uid,filename)
}
I got sam
going so far as 2.6.18. I don't have

Hi all,
Could some body let me know wrapfs sources which is compatible to Linux
2.6.18 kernel sources.
I tried to get sources using google search , but all are compatible with
latest kernel sources.
Thanks & Regards,

As part of auditing purpose I need to intercept/hook open/read/write system
calls.
I tried with below sample program. When I do a insmod of the module that
was built, my system was hanged. On some re-search I came to know that we
can not modify system call table as it is read only.

Hello all,
I've a daemon process and I'm allocating heap memory** for big character
buffers using malloc/free.
Each can take 5MB.
Though I freed/deleted memory allocated for the buffers, the increased
memory during the allocation time is not re-claiming back.This I observed
using *top* command.

Other than fanotify , I can achieve my requirement through a driver/module.
If this can be achieved through a driver/module please provide me inputs to
start.

Hi all,
Is it possible to write a module/driver which notifies file/directory change
asynchronously along with user name(or with uid) who modified it.
inotify will do change notification but it will not provide uid who
modified/created the file.
audit and inotify combination can work, but I'm lo

Hi all,
(Note : I'm writing this mail to this kernel group as I did not find any
suitable mechanism in application level for my below need).
If a file modified by some user then how can we detect that user who
modified it.
Linux audit was not suitable for my need.
Can this be achieved through
