[AF_IUCV]: Add lock when updating accept_q

2007-07-15T02:04:25+00:00

The accept_queue of an af_iucv socket will be corrupted, if adding and deleting of entries in this queue occurs at the same time (connect request from one client, while accept call is processed for another client). Solution: add locking when updating accept_q Signed-off-by: Ursula Braun Acked-by: Frank Pavlic Signed-off-by: David S. Miller

[AF_IUCV]: Implementation of a skb backlog queue

2007-05-04T19:22:07+00:00

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 .

[AF_IUCV/IUCV]: smp_call_function deadlock

2007-04-29T06:03:59+00:00

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.
