* [SCSI] introduce shost_priv helperChristoph Hellwig2007-05-311-0/+4
| | | | | | | | | | | | | | | Currently accessing the scsi host private data is rather messy because it comes as an unsigned long that always needs a cast first. This patch introduces a helper that does the cast called shost_priv. It's similar in spirit to netdev_priv for network drivers. This is the first patch introducing the macro, and the second patch in the series will convert esp and it's subdrivers as an example. Further conversion will wait until the helper is in the tree to make patch juggling easier. Signed-off-by: Christoph Hellwig <hch@lst.de> Signed-off-by: James Bottomley <James.Bottomley@SteelEye.com>

On 64 bit machines this results in a multiplication overflow in tick_nohz_stop_sched_tick(). Reported by: Dave Miller <davem@davemloft.net> Make the return value a constant and limit the return value to a 32 bit value. When the max timeout value is returned, we can safely stop the tick timer device. The max jiffies delta results in a 12 days timeout for HZ=1000. In the long term the get_next_timer_interrupt() code needs to be reworked to return ktime instead of jiffies, but we have to wait until the last users of the original NO_IDLE_HZ code are converted.

Only three limitations existed in the kernel preventing arbitrary NR_CPUS values: 1) dcache dirty cpu state stored in page->flags on D-cache aliasing platforms. With some build time calculations and some build-time BUG checks on page->flags layout, this one was easily solved. 2) The cheetah XCALL delivery code could only handle a cpumask with up to 32 cpus set. Some simple looping logic clears that up too. 3) thread_info->cpu was a u8, easily changed to a u16. There are a few spots in the kernel that still put NR_CPUS sized arrays on the kernel stack, but that's not a sparc64 specific problem. Signed-off-by: David S. Miller <davem@davemloft.net>

| | * [XFRM]: Allow packet drops during larval state resolution.David S. Miller2007-05-242-0/+10

Right now we'll block until the key manager resolves the route. That works for simple cases, but many folks would rather packets get silently dropped until the key manager resolves the IPSEC rules. We can't tell these folks to "set the socket non-blocking" because they don't have control over the non-block setting of things like the sockets used to resolve DNS deep inside of the resolver libraries in libc. With that in mind I coded up the patch below with some help from Herbert Xu which provides packet-drop behavior during larval state resolution, controllable via sysctl and off by default. This lays the framework to either: 1) Make this default at some point or... 2) Move this logic into xfrm{4,6}_policy.c and implement the ARP-like resolution queue we've all been dreaming of. The idea would be to queue packets to the policy, then once the larval state is resolved by the key manager we re-resolve the route and push the packets out. The packets would timeout if the rule didn't get resolved in a certain amount of time. Signed-off-by: David S. Miller <davem@davemloft.net>

| * | | freezer: fix vfork problemRafael J. Wysocki2007-05-232-2/+47
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Currently try_to_freeze_tasks() has to wait until all of the vforked processes exit and for this reason every user can make it fail. To fix this problem we can introduce the additional process flag PF_FREEZER_SKIP to be used by tasks that do not want to be counted as freezable by the freezer and want to have TIF_FREEZE set nevertheless. Then, this flag can be set by tasks using sys_vfork() before they call wait_for_completion(&vfork) and cleared after they have woken up. After clearing it, the tasks should call try_to_freeze() as soon as possible. Signed-off-by: Rafael J.

| * | | freezer: close potential race between refrigerator and thaw_tasksRafael J. Wysocki2007-05-231-0/+10
| |/ / | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | If the freezing of tasks fails and a task is preempted in refrigerator() before calling frozen_process(), then thaw_tasks() may run before this task is frozen. In that case the task will freeze and no one will thaw it. To fix this race we can call freezing(current) in refrigerator() along with frozen_process(current) under the task_lock() which also should be taken in the error path of try_to_freeze_tasks() as well as in thaw_process(). Moreover, if thaw_process() additionally clears TIF_FREEZE for tasks that are not frozen, we can be sure that all tasks are thawed and there are no pending "freeze" requests after thaw_tasks() has run.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | When the irq.h changes went in, the dreamcast code was still referencing an old value. Switch it back to the IRQ number, which fixes this: arch/sh/boards/dreamcast/irq.c: In function `disable_systemasic_irq': arch/sh/boards/dreamcast/irq.c:59: error: `OFFCHIP_IRQ_BASE' undeclared (first use in this function) arch/sh/boards/dreamcast/irq.c:59: error: (Each undeclared identifier is reported only once arch/sh/boards/dreamcast/irq.c:59: error: for each function it appears in.)

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Just at the time you added them on sh we're removing them from other architectures. As there's no user yet this patch just removes them completely. Once you actually have a kprobes patch it should follow the direct call to kprobes_fault_handler model that powerpc, s390 and sparc64 employ in 2.6.22-rc1 and that I'm updating other architectures to.
