hi,
   if i export these syms .. firstly ill have to
change the source/patch the kernel which is not
advisable then every time i write such a module .. ill
have to make sure that i export all these symbols and
there are no conflicts due to some wierd deps that
might be present ( u never know ! ) So i am looking
for a descent way to do the same

Still in need of help,
Amber

syscall from modules

[Amber Palekar]

 Hi,
   I am trying to write a linux kernel module.I want
 to  use sys_sendto,sys_recvfrom etc calls from the
 module.However these symbols are not present in
 'ksyms'.One sluggish option is to modify socket.c (
 which contains these function definitions ) to
 export  the symbols. However this would require
comiling the  entire kernel.Is there a descent way to
do this ??
 
 Pls help !!!
 Amber

Hi,

Just use sock_sendmsg() and sock_recvmsg() directly. They are both
exported in netsyms.c.

Cheers,
