Hi, i am trying to figure out the TCP timers code.i found these three main timer_list structures retransmit_timer delack_timer and the sk->timer for one socket. everytime the timeout value changes mod_timer() is called which detaches it from the list and then attaches it according to the new values using internal add_timer(). so when are these three timer_list structures put into the list for the first time and where. thanks a lot amit. --- - Amit http://amitshah.nav.to/ amitshah@gmx.net -- Kernelnewbies: Help each other learn about the Linux kernel.
