When you did kern_open() without creating kernel thread, it worked,
because kern_open() used file descriptor table from your current

without file descriptor table, so you can't use kern_open() and actually
you shouldn't do this either.
I understood now. Thanks
Take a look at sys/cddl/compat/opensolaris/kern/opensolaris_kobj.c,
where you can find functions to do what you want.
I guess you already considered doing all this in userland?:)
I'm not deploying this http server for any production, i just want to
study its performance compared to a userland http server.
And to experience FreeBSD kernel hacking.
I'm still trying to figure out, how to play with soreceive() now.
But Thanks a lot, It's now clearer for me.

have a look at the netgraph modules.
There is a module called ksocket that allows other netgraph modules to
use sockets. more than one person has implemented an in-kernel http
server in a netgraph module.
