* Replacing tcp_v4_rcv from a module @ 2003-11-25 8:21 Gong Su 2003-11-25 9:29 ` Raj 0 siblings, 1 reply; 3+ messages in thread From: Gong Su @ 2003-11-25 8:21 UTC (permalink / raw) To: linux-kernel I need some customized function inside tcp_v4_rcv so I wrote a module to replace tcp_protocol->handler with my own function pointer; and currently my own tcp_v4_rcv is just a copy of the original tcp_v4_rcv. But as soon as traffic came in, my machine locks up hard. I can't think of a reason why it would do so since I've changed other functions the same way, e.g., replacing ip_packet_type->func with my own ip_rcv function pointer without problem. Am I missing something obvious? Thanks for any enlightenment. -- /Gong ^ permalink raw reply [flat|nested] 3+ messages in thread

Sorry I forgot to say that I'm doing this on 2.4. Is this a 2.5 function? I can't find it in the 2.4 source tree. -- /Gong Thus did Raj <raju@mailandnews.com> write: *>Gong Su wrote: *> *>>I need some customized function inside tcp_v4_rcv so I wrote a module to *>>replace tcp_protocol->handler with my own function pointer; and currently *>> *>> *>Try calling synchronize_net() after your modification and see if it helps. *> *>/Raj *> ^ permalink raw reply [flat|nested] 3+ messages in thread
