Hello, I have a 2.6.9-22 kernel (RedHat Enterprise 4 ). I wrote a kernel module which monitors the sk_buff traffic. However, the timestamp is 0 for the sk_buff packets. Is there a way to enable this timestamp ? I want to add that in newer kernels, for example, 2.6.14-1 (FC4) or 2.6.18-1 (FC6) there is a method called net_enable_timestamp() and when I call this method from my module I can get valid timestamps from my module. In these kernels, net_enable_timestamp() method is exported; when runnin cat cat /proc/kallsyms | grep net_enable_time you get: ffffffff80409702 T net_enable_timestamp However, in 2.6.9-22, "cat /proc/kallsyms | grep net_enable_time" gives nothing. Moreover, I tried to add include "net/sock.h" and add atomic_inc(&netstamp_needed) (which is what in fact net_enable_time() does in newer kernel). Building the module succeeds, but it gives a warning: Warning: "netstamp_needed"undefined! (though the *.ko is created). Any ideas what should I do ?
