2010-02-17CAPI: Rework application lockingJan Kiszka2-34/+29
Drop the application rw-lock in favour of RCU. This synchronizes capi20_release against capi_ctr_handle_message which may dereference an application from (soft-)IRQ context. Any other access to the application list is now protected by the capi_controller_lock as well. This also allows to safely inspect applications for /proc dumping by holding capi_controller_lock. At this chance, drop some useless release_in_progress checks where we obtained the application pointer from the list (which becomes NULL on release_in_progress).

2010-02-17CAPI: Rework locking of controller data structuresJan Kiszka3-87/+214
This patch applies the mutex so far only protecting the controller list to (almost) all accesses of controller data structures. It also reworks waiting on state changes in old_capi_manufacturer so that it no longer poll and holds a module reference to the controller owner while waiting (the latter was partly done already). Modification and checking of the blocked state remains racy by design, the caller is responsible for dealing with this. Signed-off-by: Jan Kiszka <jan.kiszka@web.de> Signed-off-by: David S.

2010-02-17CAPI: Rework controller state notifierJan Kiszka2-67/+67
Another step towards proper locking: Rework the callback provided to capidrv for controller state changes. This is so far attached to an application, which would require us to hold the corresponding lock across notification calls. But there is no direct relation between a controller up/down event and an application, so let's decouple them and provide a notifier call chain for those events instead. This notifier chain is first of all used internally. Here we request the highest priority to unsure that housekeeping work is done before any other notifications. The chain is exported via [un]register_capictr_notifier to our only user, capidrv, to replace the racy and unfixable capi20_set_callback.

2010-02-17CAPI: Rework capi_ctr_ready/downJan Kiszka1-45/+50
This step prepares the application of proper controller locking: Push all state changing work into the notify handler that are called by capi_ctr_ready and capi_ctr_down, switch detach_capi_ctr to issue a synchronous ctr_down. Also ensure that we do not go through any action if the state did not change. Signed-off-by: Jan Kiszka <jan.kiszka@web.de> Signed-off-by: David S. Miller <davem@davemloft.net>

2010-02-13tg3: Unwedge stuck MSI-X vectorsMatt Carlson2-10/+20
The previous patch changed the code so that new rx buffer submissions to the hardware stall if a new submission would overwrite data needed by an unserviced rx packet. On very busy 5717 and 57765 asic rev devices, there is a corner case where the hardware will fail to assert an MSI-X interrupt for rx traffic. If that vector's interrupt never has another reason to assert, any rx buffers held will never be serviced. If the buffers are never serviced and the hardware consumes all the available rx packets for other rx rings, deadlock will result. The most reliable and least intrusive way to work around the problem is to detect the case where new submissions would overwrite existing data and force all rx interrupt vectors to fire.
