Ok, loop is simulating a "keep-alive" tcp conection but I don't want to do in way like this.
I want to create one to one connection this mean one tcp connection for one HTTP request and response so I cant check ( parse ) HTTP header.
If HTTP request header contains field with size of itself then there is no problem but
in HTTP request header there is no field like this therefor I dont know when stop(break) the loop.
Mmmmm it looks like the end of header are magick chars \r\n\n or somethig like this Maybe I can solve my simple problem with this
but question is: Is this optimal for HTTP header I mean reading char by char?
PS
"Why do you want to do this in kernel space instead of user space?? "
I get this question minimum once a day
I want to learn this network interface inside a kernel.

NETWORK_NAMESPACES(7) Linux Programmer's Manual NETWORK_NAMESPACES(7)NAME
network_namespaces - overview of Linux network namespaces
DESCRIPTION
Network namespaces provide isolation of the system resources associated with networking: network devices, IPv4 and IPv6 protocol stacks, IP
routing tables, firewall rules, the /proc/net directory (which is a symbolic link to /proc/PID/net), the /sys/class/net directory, various
files under /proc/sys/net, port numbers (sockets), and so on.
A physical network device can live in exactly one network namespace. When a network namespace is freed (i.e., when the last process in the
namespace terminates), its physical network devices are moved back to the initial network namespace (not to the parent of the process).
A virtual network (veth(4)) device pair provides a pipe-like abstraction that can be used to create tunnels between network namespaces, and
can be used to create a bridge to a physical network device in another namespace. When a namespace is freed, the veth(4) devices that it
contains are destroyed.
Use of network namespaces requires a kernel that is configured with the CONFIG_NET_NS option.
