* net: implement a SO_PROTOCOL getsockoptionJan Engelhardt2009-08-0518-0/+33
| | | | | | | | | | | | | | | Similar to SO_TYPE returning the socket type, SO_PROTOCOL allows to retrieve the protocol used with a given socket. I am not quite sure why we have that-many copies of socket.h, and why the values are not the same on all arches either, but for where hex numbers dominate, I use 0x1029 for SO_PROTOCOL as that seems to be the next free unused number across a bunch of operating systems, or so Google results make me want to believe. SO_PROTOCOL for others just uses the next free Linux number, 38. Signed-off-by: Jan Engelhardt <jengelh@medozas.de> Signed-off-by: David S. Miller <davem@davemloft.net>

* net/compat/wext: send different messages to compat tasksJohannes Berg2009-07-153-4/+4
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Wireless extensions have the unfortunate problem that events are multicast netlink messages, and are not independent of pointer size. Thus, currently 32-bit tasks on 64-bit platforms cannot properly receive events and fail with all kinds of strange problems, for instance wpa_supplicant never notices disassociations, due to the way the 64-bit event looks (to a 32-bit process), the fact that the address is all zeroes is lost, it thinks instead it is 00:00:00:00:01:00. The same problem existed with the ioctls, until David Miller fixed those some time ago in an heroic effort. A different problem caused by this is that we cannot send the ASSOCREQIE/ASSOCRESPIE events because sending them causes a 32-bit wpa_supplicant on a 64-bit system to overwrite its internal information, which is worse than it not getting the information at all -- so we currently resort to sending a custom string event that it then parses. This, however, has a severe size limitation we are frequently hitting with modern access points; this limitation would can be lifted after this patch by sending the correct binary, not custom, event. A similar problem apparently happens for some other netlink users on x86_64 with 32-bit tasks due to the alignment for 64-bit quantities. In order to fix these problems, I have implemented a way to send compat messages to tasks. When sending an event, we send the non-compat event data together with a compat event data in skb_shinfo(main_skb)->frag_list. Then, when the event is read from the socket, the netlink code makes sure to pass out only the skb that is compatible with the task. This approach was suggested by David Miller, my original approach required always sending two skbs but that had various small problems. To determine whether compat is needed or not, I have used the MSG_CMSG_COMPAT flag, and adjusted the call path for recv and recvfrom to include it, even if those calls do not have a cmsg parameter. I have not solved one small part of the problem, and I don't think it is necessary to: if a 32-bit application uses read() rather than any form of recvmsg() it will still get the wrong (64-bit) event. However, neither do applications actually do this, nor would it be a regression. Signed-off-by: Johannes Berg <johannes@sipsolutions.net> Signed-off-by: David S. Miller <davem@davemloft.net>

| * | parisc: fix "delay!" timer handlingGrant Grundler2009-07-031-35/+53

If we used floating point math to compute the number of ticks that had elapsed since the last timer interrupt, it could take up to 12K cycles (emperical!) to handle the interrupt. Existing code assumed it would never take more than 8k cycles. We end up programming Interval Timer to a value less than "current" cycle counter. Thus have to wait until Interval Timer "wrapped" and would then get the "delayed!" printk that I moved below. Since we don't really know what the upper limit is, I prefer to read CR16 again after we've programmed it to make sure we won't have to wait for CR16 to wrap. Further, the printk was between reading CR16 (cycle couner) and writing CR16 (the interval timer). This would cause us to continue to set the interval timer to a value that was "behind" the cycle counter. Rinse and repeat. So no printk's between reading CR16 and setting next interval timer.

The change has had a few days testing with a SMP build of 2.6.22.19 running on a rp3440. This patch is about the correctness of the __ldcw() macro itself.

We should switch the macro in the linker script to INIT_TASK_DATA. (Sorry that I missed this in reviewing the patch). Since the macros are new, there is only one user of the INIT_TASK in vmlinux.lds.h, arch/mn10300/kernel/vmlinux.lds.S. However, we are currently using INIT_TASK_DATA for laying down an entire .data.init_task section. So rename that to INIT_TASK_DATA_SECTION. I would be worried about changing the meaning of INIT_TASK_DATA, but the old INIT_TASK_DATA implementation had no users, and in fact if anyone had tried to use it, it would have failed to compile because it didn't pass the alignment to the old INIT_TASK.
