sock_sendmsg from interrupt context

["endeavor john" <jendeavor@xxxxxxxxx>]

Hello Team,

   We are writing a "virtual serial port driver"
   which in turn usesTCP Sockets to send databuffers from chardev interface across  network.

 

   Since we should not be calling sock_send msg from interrupt context,

Is there any other alterative call that we can use to send messages over TCP sockets

From interrupt context.

 

To explain the scenario :

When we invoke our driver from ppp through ping,

ppp_write ->tty_layer..... my_serial_driver_write(..,userbuffer, )

 

my_serial_driver_write(struct tty_struct *tty,userdatabuffer,int buff_len )

{

   msg.iov.iov_base=userdatabuffer;

   sock_sendmsg();

}

 

Since sock_sendmsg calls many sleep calls like might_sleep we are not supposed use them, so can u plz suggest me if there is any other way of passing the data.

Regards,

J.ENDEAVOR
