* Bluetooth: Remove hci_recv_stream_fragment functionMarcel Holtmann2015-04-071-3/+0
| | | | | | | | | | | | | | | | The hci_recv_stream_fragment function should have never been introduced in the first place. The Bluetooth core does not need to know anything about the HCI transport protocol. With all transport protocol specific detailed moved back into the drivers where they belong (mainly generic USB and UART drivers), this function can now be removed. This reduces the size of hci_dev structure and also removes an exported symbol from the Bluetooth core module.

| * Bluetooth: Convert local OOB data reading to use HCI requestJohan Hedberg2015-04-021-3/+0
| | | | | | | | | | | | | | | | | | | | | | | | Now that there's a HCI request API available where the callback receives the resulting skb, we can convert the local OOB data reading to use this new API. This patch does the necessary update in mgmt.c (which also requires moving the callback higher up since it's now a static function) and removes the custom calls from hci_event.c that are no-longer necessary.

| | | | | | | | | | | | | | | | | | | | | | Now that there's an API in place that allows passing the resulting skb to the request callback we can conveniently convert the hci_req_sync and related functions to use it. Since we still need to get the skb from the async callback into the sleeping _sync() function the patch adds another req_skb variable to hci_dev where the sync request state is tracked.

| * Bluetooth: Add second hci_request callback option for full skbJohan Hedberg2015-04-021-0/+3
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This patch adds a second possible callback for HCI requests where the callback will receive the full skb of the last successfully completed HCI command. This API is useful for cases where we want to use a request to read some data and the existing hci_event.c handlers do not store it e.g. in the hci_dev struct. The reason the patch is a bit bigger than just adding the new API is because the hci_req_cmd_complete() functions required some refactoring to enable it: now hci_req_cmd_complete() is simply used to request the callback pointers if any, and the actual calling of them happens from a single place at the end of hci_event_packet(). The reason for this is that we need to pass the original skb (without any skb_pull, etc modifications done to it) and it's simplest to keep track of it within the hci_event_packet() function.

| * Bluetooth: Refactor HCI request variables into own structJohan Hedberg2015-03-301-4/+10
| | | | | | | | | | | | | | | | | | | | In order to shrink the size of bt_skb_cb, this patch moves the HCI request related variables into their own req_ctrl struct. Additionall the L2CAP and HCI request structs are placed inside the same union since they will never be used at the same time for the same skb.

| * Bluetooth: Refactor L2CAP variables into l2cap_ctrlJohan Hedberg2015-03-301-4/+4
| | | | | | | | | | | | | | | | | | | | | | We're getting very close to the maximum possible size of bt_skb_cb. To prepare to shrink the struct with the help of a union this patch moves all L2CAP related variables into the l2cap_ctrl struct. To later add other 'ctrl' structs the L2CAP one is renamed simple 'l2cap' instead of 'control'.

| * | ipv6: protect skb->sk accesses from recursive dereference inside the stackhannes@stressinduktion.org2015-04-063-17/+4

Otherwise local socket settings could influence the result of e.g. tunnel encapsulation process. ipv6 does not conform with this in three places: 1) ip6_fragment: we do consult ipv6_npinfo for frag_size 2) sk_mc_loop in ipv6 uses skb->sk and checks if we should loop the packet back to the local socket 3) ip6_skb_dst_mtu could query the settings from the user socket and force a wrong MTU Furthermore: In sk_mc_loop we could potentially land in WARN_ON(1) if we use a PF_PACKET socket ontop of an IPv6-backed vxlan device. Reuse xmit_recursion as we are currently only interested in protecting tunnel devices.

One possible use-case is cleaning up interface state after HW recovery. Some interfaces that were up before the recovery took place might be down now, but they might still be "dirty".

IMPORTANT: Three sync_* parameters - sync_ts, sync_device_ts and sync_dtim_count would possibly be out of sync by the time the driver will use them.

Basically, nf_tables updates to add the set extension infrastructure and finish the transaction for sets from Patrick McHardy. More specifically, they are: 1) Move netns to basechain and use recently added possible_net_t, from Patrick McHardy. 2) Use LOGLEVEL_<FOO> from nf_log infrastructure, from Joe Perches. 3) Restore nf_log_trace that was accidentally removed during conflict resolution. 4) nft_queue does not depend on NETFILTER_XTABLES, starting from here all patches from Patrick McHardy. 5) Use raw_smp_processor_id() in nft_meta. Then, several patches to prepare ground for the new set extension infrastructure: 6) Pass object length to the hash callback in rhashtable as needed by the new set extension infrastructure. 7) Cleanup patch to restore struct nft_hash as wrapper for struct rhashtable 8) Another small source code readability cleanup for nft_hash. 9) Convert nft_hash to rhashtable callbacks. And finally... 10) Add the new set extension infrastructure. 11) Convert the nft_hash and nft_rbtree sets to use it. 12) Batch set element release to avoid several RCU grace period in a row and add new function nft_set_elem_destroy() to consolidate set element release. 13) Return the set extension data area from nft_lookup. 14) Refactor existing transaction code to add some helper functions and document it. 15) Complete the set transaction support, using similar approach to what we already use, to activate/deactivate elements in an atomic fashion. ==================== Signed-off-by: David S.

Implement similar to the existing rule transactions: The global transaction counter keeps track of two generations, current and next. Each element contains a bitmask specifying in which generations it is inactive. New elements start out as inactive in the current generation and active in the next. On commit, the previous next generation becomes the current generation and the element becomes active. The bitmask is then cleared to indicate that the element is active in all future generations. If the transaction is aborted, the element is removed from the set before it becomes active. When removing an element, it gets marked as inactive in the next generation. On commit the next generation becomes active and the therefor the element inactive. It is then taken out of then set and released. On abort, the element is marked as active for the next generation again. Lookups ignore elements not active in the current generation. The current set types (hash/rbtree) both use a field in the extension area to store the generation mask. This (currently) does not require any additional memory since we have some free space in there. Signed-off-by: Patrick McHardy <kaber@trash.net> Signed-off-by: Pablo Neira Ayuso <pablo@netfilter.org>

The set implementations' ->remove() functions are changed to only take the element out of their internal data structures. Elements will be freed in a batched fashion after the global transaction's completion RCU grace period. This reduces the amount of grace periods required for nft_hash from N to zero additional ones, additionally this guarantees that the set elements' extensions of all implementations can be used under RCU protection.

Element allocation and initialization is performed centrally by nf_tables_api instead of by the different set implementations' ->insert() functions. A new "elemsize" member in the set ops specifies the amount of memory to reserve for internal usage. Destruction will also be moved out of the set implementations by a following patch. Except for element allocation, the patch is a simple conversion to using data from the extension area.
