llc: make lock static

The llc_sap_list_lock does not need to be global, only acquired in core. Signed-off-by: Stephen Hemminger Signed-off-by: David S. Miller

llc*.h: Remove extern from function prototypes

2013-09-21T18:01:38Z

There are a mix of function prototypes with and without extern in the kernel sources. Standardize on not using extern for function prototypes. Function prototypes don't need to be written with extern. extern is assumed by the compiler. Its use is as unnecessary as using auto to declare automatic/local variables in a block.

llc2: Fix silent failure of llc_station_init()

2012-08-14T23:51:18Z

llc_station_init() creates and processes an event skb with no effect other than to change the state from DOWN to UP. Allocation failure is reported, but then ignored by its caller, llc2_init(). Remove this possibility by simply initialising the state as UP. Signed-off-by: Ben Hutchings Signed-off-by: David S. Miller

llc: replace the socket list with a local address based hash

2009-12-27T04:45:32Z

For the cases where a lot of interfaces are used in conjunction with a lot of LLC sockets bound to the same SAP, the iteration of the socket list becomes prohibitively expensive. Replacing the list with a a local address based hash significantly improves the bind and listener lookup operations as well as the datagram delivery. Connected sockets delivery is also improved, but this patch does not address the case where we have lots of sockets with the same local address connected to different remote addresses. In order to keep the socket sanity checks alive and fast a socket counter was added to the SAP structure. Signed-off-by: Octavian Purdila Signed-off-by: David S. Miller

llc: use a device based hash table to speed up multicast delivery

2009-12-27T04:43:57Z

This patch adds a per SAP device based hash table to solve the multicast delivery scalability issue when we have large number of interfaces and a large number of sockets bound to the same SAP. Signed-off-by: Octavian Purdila Signed-off-by: David S. Miller

llc: convert the socket list to RCU locking

2009-12-27T04:41:43Z

For the reclamation phase we use the SLAB_DESTROY_BY_RCU mechanism, which require some extra checks in the lookup code: a) If the current socket was released, reallocated & inserted in another list it will short circuit the iteration for the current list, thus we need to restart the lookup. b) If the current socket was released, reallocated & inserted in the same list we just need to recheck it matches the look-up criteria and if not we can skip to the next element. In this case there is no need to restart the lookup, since sockets are inserted at the start of the list and the worst that will happen is that we will iterate throught some of the list elements more then once. Note that the /proc and multicast delivery was not yet converted to RCU, it still uses spinlocks for protection. Signed-off-by: Octavian Purdila Signed-off-by: David S. Miller
