Using the following dtrace command, I can see who''s calling what with lots of +/- numbers: dtrace -n ''fbt:ip:ip_output:entry{@dbtypes[((mblk_t *)arg1)->b_datap->db_type,caller] = count();}'' ...the output is what I want but not how I want to see it. What I''d rather see is the function names associated with caller and for db_type to be output in hex. Looking at the docs online for s10, http...

[FreeBSD 7-STABLE/i386] Hello, I've got a 100 % reproductible panic with ipsec when using a 'ping -s 4000'.

Hi, I have 2 servers which are connected to a gateway machine. The gateway and one server are running Linux 2.6.16.2, while the third machine is running 2.6.16.5. The two ethernet ports on the gateway which are connected to the servers are combined into a single ethernet bridge device. Ever since 2.6.16, I have noticed that I can no longer cross-mount the two servers' /home directories via

...th zero. As a result control falls through until the default class is selected. The small test I am using is that my application simply sets all of the outgoing data to a single priority. And it is not set to the default :-) I have tracked it down as far as the ip_queue_xmit function in net/ipv4/ip_output.c. There the skb->priority and the skb->sk field are correct however we go through the NF_HOOK, which is where I got lost. There is no reason I can think of that a socket should lose any of it''s options between these two points in the code. Could someone who understands the interm...
