What's the original source of the client name you're passing in? Are you reusing that buffer?
Because your "add_client()" code never makes a copy of that string, it just uses the address of the string that gets passed in. If you reuse the original string, you'll change the data in the node on the linked list.

Hi, I am programming in kernel, and I want to use a double linked list that holds infos that every process could access and modify THIS list.

genders_getnodename
GENDERS_GETNODENAME(3) LIBGENDERS GENDERS_GETNODENAME(3)
NAME
genders_getnodename - get the current node name
SYNOPSIS
#include <genders.h>
int genders_getnodename(genders_t handle, char *node, int len);
DESCRIPTION
genders_getnodename() retrieves the name of the node that the function is being called from. The node name returned is the shortened host-
name of the node and is stored in the buffer pointed to be node. len should indicate the length of the buffer. The node returned by gen-
ders_getnodename() is the shortened hostname of the node.
To avoid passing in a buffer that is not large enough to store the node name, genders_getmaxnodelen(3) should be used to determine the min-
imum buffer size that should be used.
RETURN VALUES
On success, 0 is returned. On error, -1 is returned, and an error code is returned in handle. The error code can be retrieved via gen-
ders_errnum(3) , and a description of the error code can be retrieved via genders_strerror(3). Error codes are defined in genders.h.
ERRORS
GENDERS_ERR_NULLHANDLE
The handle parameter is NULL. The genders handle must be created with genders_handle_create(3).
GENDERS_ERR_NOTLOADED
genders_load_data(3) has not been called to load genders data.
GENDERS_ERR_OVERFLOW
The buffer pointed to by node is not large enough to store the node name.
GENDERS_ERR_PARAMETERS
An incorrect parameter has been passed in.
GENDERS_ERR_MAGIC
handle has an incorrect magic number. handle does not point to a genders handle or handle has been destroyed by genders_han-
dle_destroy(3).
