2010-02-16CAPI: Convert capidev_list_lock into a mutexJan Kiszka
No need for anything "harder" here (specifically no need for irqsave...). Also, make the list removal the first operation of capidev_free to avoid dumping half-released devices via /proc. Signed-off-by: Jan Kiszka <jan.kiszka@web.de> Signed-off-by: David S. Miller <davem@davemloft.net>
2010-02-16CAPI: Reduce #ifdef mess around CONFIG_ISDN_CAPI_MIDDLEWAREJan Kiszka
Make the code a bit more readable be providing stub functions for the !CONFIG_ISDN_CAPI_MIDDLEWARE case. Though a few lines are moved around, this comes with no functional changes. Signed-off-by: Jan Kiszka <jan.kiszka@web.de> Signed-off-by: David S. Miller <davem@davemloft.net>
2010-02-16CAPI: Rework application lockingJan Kiszka
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).

2010-02-16CAPI: Rework locking of controller data structuresJan Kiszka
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. Miller <davem@davemloft.net>
2010-02-16CAPI: Rework controller state notifierJan Kiszka
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.

2010-02-16CAPI: Rework capi_ctr_ready/downJan Kiszka
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>

2010-02-16CAPI: Call a controller 'controller', not 'card'Jan Kiszka
At least for our internal use, fix the misnomers that refer to a CAPI controller as 'card'. No functional changes. Signed-off-by: Jan Kiszka <jan.kiszka@web.de> Signed-off-by: David S. Miller <davem@davemloft.net>
2010-02-16CAPI: Reduce chattiness during module loading/removalJan Kiszka
The CVS revisions dumped by all CAPI modules are meaningless today. And that some CAPI module is loaded or removed does not necessarily deserve a message. Just keep the message of the central module, capi.ko, drop the rest. Signed-off-by: Jan Kiszka <jan.kiszka@web.de> Signed-off-by: David S. Miller <davem@davemloft.net>
2010-02-16CAPI: Pin capifs instead of mounting itJan Kiszka
Auto-mounting the capifs during module init prevents unloading its module. Instead, pin the filesystem as long as some NCCI node exists. Signed-off-by: Jan Kiszka <jan.kiszka@web.de> Signed-off-by: David S. Miller <davem@davemloft.net>

2010-02-16CAPI: Sanitize capifs APIJan Kiszka
Instead of looking up the dentry of an NCCI node again in capifs_free_ncci pass the pointer via the capifs user. This patch also reduces the #ifdef mess in capi.c a bit as far as capifs was causing it. Signed-off-by: Jan Kiszka <jan.kiszka@web.de> Signed-off-by: David S. Miller <davem@davemloft.net>
2010-02-16CAPI: Fix leaks in capifs_new_ncciJan Kiszka

2010-02-16net neigh: Decouple per interface neighbour table controls from binary sysctlsEric W. Biederman
Stop computing the number of neighbour table settings we have by counting the number of binary sysctls. This behaviour was silly and meant that we could not add another neighbour table setting without also adding another binary sysctl. Don't pass the binary sysctl path for neighour table entries into neigh_sysctl_register. These parameters are no longer used and so are just dead code. Signed-off-by: Eric W.

2010-02-15net/macvtap: fix reference countingArnd Bergmann
The RCU usage in the original code was broken because there are cases where we possibly sleep with rcu_read_lock held. As a fix, change the macvtap_file_get_queue to get a reference on the socket and the netdev instead of taking the full rcu_read_lock.

with 32 bit userland and 64 bit kernels, it is unlikely but possible that insertion of new rules fails even tough there are only about 2000 iptables rules. This happens because the compat delta is using a short int. Easily reproducible via "iptables -m limit" ; after about 2050 rules inserting new ones fails with -ELOOP.
