An iucv deadlock may occur, where one CPU is spinning on the iucv_table_lock for iucv_tasklet_fn(), while another CPU is holding the iucv_table_lock for an iucv_path_connect() and is waiting for the first CPU in an smp_call_function. Solution: replace spin_lock in iucv_tasklet_fn by spin_trylock and reschedule tasklet in case of non-granted lock.

由 Rafael J. Wysocki 提交于
Since nonboot CPUs are now disabled after tasks and devices have been frozen and the CPU hotplug infrastructure is used for this purpose, we need special CPU hotplug notifications that will help the CPU-hotplug-aware subsystems distinguish normal CPU hotplug events from CPU hotplug events related to a system-wide suspend or resume operation in progress. This patch introduces such notifications and causes them to be used during suspend and resume transitions. It also changes all of the CPU-hotplug-aware subsystems to take these notifications into consideration (for now they are handled in the same way as the corresponding "normal" ones).

With the inital implementation we missed to implement a skb backlog queue . The result is that socket receive processing tossed packets. Since AF_IUCV connections are working synchronously it leads to connection hangs. Problems with read, close and select also occured. Using a skb backlog queue is fixing all of these problems .

Calling smp_call_function can lead to a deadlock if it is called from tasklet context. Fixing this deadlock requires to move the smp_call_function from the tasklet context to a work queue. To do that queue the path pending interrupts to a separate list and move the path cleanup out of iucv_path_sever to iucv_path_connect and iucv_path_pending. This creates a new requirement for iucv_path_connect: it may not be called from tasklet context anymore. Also fixed compile problem for CONFIG_HOTPLUG_CPU=n and another one when walking the cpu_online mask. When doing this, we must disable cpu hotplug.

Spring cleaning time... There seems to be a lot of places in the network code that have extra bogus semicolons after conditionals.

For the common, open coded 'skb->h.raw = skb->data' operation, so that we can later turn skb->h.raw into a offset, reducing the size of struct sk_buff in 64bit land while possibly keeping it as a pointer on 32bit. This one touches just the most simple cases: skb->h.raw = skb->data; skb->h.raw = {skb_push|[__]skb_pull}() The next ones will handle the slightly more "complex" cases.
