Hi All, I need to send the packets from ppp to another user space application thro' sockets. To do this I invoked the kernel level call sock_sendmsg from the function ppp_sync_push. Instead of calling the tty->driver.write function, i have modified the code to invoke my function which will send packet to the socket..But it crashes..It says alloc_skb called nonatomically from interrupt. It is crashing inside the function sock_sendmsg Is the ppp_sync_push function runs in the context of tty interrupt? Do i need to insert the hook prior to this..?where should i hook my proprietary function.? Thanks, Vanitha -- Kernelnewbies: Help each other learn about the Linux kernel.
