site_archiver(a)lists.apple.com Delivered-To: darwin-kernel(a)lists.apple.com HI, If i want to freeze the live volumes,what sorts of mechanisms one must use to perform the freezing of live volumes,or how should i approach for freezing of live volumes so that i can copy the meta data to other location in the mean time.Any pointers certainly helps to make a correct approach toward this functionality.

AppleRAID lives at the IOMedia level of IOKit - above the device drivers, but just below the BSD layer. It fits into the system the same way a partition scheme does (you can think of a RAID volume as a partition that spans multiple disks). If you have a RAID volume set up and mounted, you can run "ioreg -l" and see how the objects stack up in the IORegistry. We also want to know the hierarchy of classes and driver families involved in the AppleRAID. AppleRAID is public source in Darwin, so you can check it out and examine it. It is important to note that the AppleRAID classes are not suitable for subclassing; they do not provide any API for developers to use. This email sent to site_archiver(a)lists.apple.com

Then, a user-land app can determine if the packet should be sent (by asking the user) and then return to the kernel. Thus, there is no NKE needed. I am not sure though. If you have already investigated that, then I'm sorry for the noise. :-) Because I am writing an application based firewall. With easy to configure rules, and alerts on an outgoing connection you don't have a rule for. I have written a Socket NKE filter that filters UDP traffic, in the send function I want to know what the foreign ip address is and the port number. I have tried a couple of ways, and both don't work: Here is what I have tried: static int tl_send2(struct socket *so, struct sockaddr **nam, struct uio **uio, struct mbuf **m, struct mbuf **control, int *flags, struct kextcb *kp) { boolean_t funnel_state; funnel_state = thread_funnel_set(network_flock, TRUE); printf("UDP: %d\n",current_proc()->p_pid); if(nam && *nam) { struct sockaddr_in * jk = (struct sockaddr_in *)*nam; printf("Here: %s\n", inet_ntoa(jk->sin_addr)); printf("Sorry: %u\n", jk->sin_addr.s_addr); } else { // what to do if it falls in the else clause? printf("Sorry: It is not null jaffa\n"); } I need to know what to do if it falls in the else statement of this if else. _______________________________________________ Do not post admin requests to the list.
