* ieee802154: rework cca settingAlexander Aring2014-12-195-9/+10
| | | | | | | | | | The current cca setting handle is a driver specific call. We need to introduce some 802.15.4 specific layer and mapping 802.15.4 cca modes to driver specific ones inside the 802.15.4 driver. This patch will add such 802.15.4 layer and mapping the cca settings to driver specific ones.

| * mac80211: free management frame keys when removing stationJohannes Berg2014-12-171-1/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | When writing the code to allow per-station GTKs, I neglected to take into account the management frame keys (index 4 and 5) when freeing the station and only added code to free the first four data frame keys. Fix this by iterating the array of keys over the right length.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | When the channel switch has been made, a vif is now using the channel context which was reserved. When that happens, we need to update the channel context since its parameters may change. I hit a case in which I switched to a 40Mhz channel but the reserved channel context was still on 20Mhz. The rate control would try to send 40Mhz packets on a 20Mhz channel context and that made iwlwifi's firmware unhappy.

In case no match is found in the advertising data, the scan response is ignored and not checked against the filter. This will lead to events being filtered wrongly. Change the code to actually only drop the events when the scan response data is not present. If it is present, it needs to be checked against the provided filter. The patch is a bit more complex than it needs to be. That is because it also fixes this compiler warning that some gcc versions produce.

This can result in use after free if there is another operation that is removing a socket at the same time. Solving this requires both holding the appropriate lock and checking the refcount to ensure that it has not already hit zero.

Since hci_unregister_dev() calls hci_dev_do_close() first that'd so far have caused "not powered" responses to be sent. Skipping the HCI_UNREGISTER case in mgmt_powered() is also not a solution since before reaching the mgmt_index_removed() stage any hci_conn callbacks (e.g. used by pairing) will get called, thereby causing "disconnected" status responses to be sent. The fix that covers all scenarios is to handle both INVALID_INDEX and NOT_POWERED responses through the mgmt_powered() function. The INVALID_INDEX response sending from mgmt_index_removed() is left untouched since there are a couple of places not related to powering off or removing an adapter that call it (e.g. configuring a new bdaddr).

Move the execution of both commands into the 3rd phase of the init procedure. And then check the bit mask of supported commands before adding them to the init sequence. With this re-ordering of the init sequence, the extra check for AVM BlueFritz! controllers is no longer needed. They will report that these two commands are not supported.

It is the later pulled before the real GRE header is constructed. The inner mac was thus set differently in nbma case: the GRE header has been pushed by neighbor layer, and mac header points to beginning of the temporary gre header (set by dev_queue_xmit). Now that the offloads expect mac header to point to the gre payload, fix the xmit patch to: - pull first the temporary gre header away - and reset mac header to point to gre payload This fixes tso to work again with nbma tunnels.

This is a discussed follow-up that, instead, extends the sock API and adds sock_kzfree_s(), which internally uses kzfree() instead of kfree() for passing the buffers back to slab. Having sock_kzfree_s() allows to keep the changes more minimal by just having a drop-in replacement instead of adding memzero_explicit() calls everywhere before sock_kfree_s(). In kzfree(), the compiler is not allowed to optimize the memset() away and thus there's no need for memzero_explicit(). Both, sock_kfree_s() and sock_kzfree_s() are wrappers for __sock_kfree_s() and call into kfree() resp. kzfree(); here, __sock_kfree_s() needs to be explicitly inlined as we want the compiler to optimize the call and condition away and thus it produces e.g. on x86_64 the _same_ assembler output for sock_kfree_s() before and after, and thus also allows for avoiding code duplication.

Specifically in the case of adding a new leaf that triggers a new node to be added that takes the place of the old node. The result is a trie where the 1 child tnode is on one side and one leaf is on the other which gives you a very deep trie. Below is the script I used to generate a trie on dummy0 with a 10.X.X.X family of addresses. ip link add type dummy ipval=184549374 bit=2 for i in `seq 1 23` do ifconfig dummy0:$bit $ipval/8 ipval=`expr $ipval - $bit` bit=`expr $bit \* 2` done cat /proc/net/fib_triestat Running the script before the patch: Local: Aver depth: 10.82 Max depth: 23 Leaves: 29 Prefixes: 30 Internal nodes: 27 1: 26 2: 1 Pointers: 56 Null ptrs: 1 Total size: 5 kB After applying the patch and repeating: Local: Aver depth: 4.72 Max depth: 9 Leaves: 29 Prefixes: 30 Internal nodes: 12 1: 3 2: 2 3: 7 Pointers: 70 Null ptrs: 30 Total size: 4 kB What this fix does is start the rebalance at the newly created tnode instead of at the parent tnode. This way if there is a gap between the parent and the new node it doesn't prevent the new tnode from being coalesced with any pre-existing nodes that may have been pushed into one of the new nodes child branches.

From Eric Dumazet. 18) Limit GSO packets to half the current congestion window, from Eric Dumazet. 19) Add a generic helper so that all drivers set their RSS keys in a consistent way, from Eric Dumazet. 20) Add xmit_more support to enic driver, from Govindarajulu Varadarajan. 21) Add VLAN packet scheduler action, from Jiri Pirko. 22) Support configurable RSS hash functions via ethtool, from Eyal Perry. * git://git.kernel.org/pub/scm/linux/kernel/git/davem/net-next: (1820 commits) Fix race condition between vxlan_sock_add and vxlan_sock_release net/macb: fix compilation warning for print_hex_dump() called with skb->mac_header net/mlx4: Add support for A0 steering net/mlx4: Refactor QUERY_PORT net/mlx4_core: Add explicit error message when rule doesn't meet configuration net/mlx4: Add A0 hybrid steering net/mlx4: Add mlx4_bitmap zone allocator net/mlx4: Add a check if there are too many reserved QPs net/mlx4: Change QP allocation scheme net/mlx4_core: Use tasklet for user-space CQ completion events net/mlx4_core: Mask out host side virtualization features for guests net/mlx4_en: Set csum level for encapsulated packets be2net: Export tunnel offloads only when a VxLAN tunnel is created gianfar: Fix dma check map error when DMA_API_DEBUG is enabled cxgb4/csiostor: Don't use MASTER_MUST for fw_hello call net: fec: only enable mdio interrupt before phy device link up net: fec: clear all interrupt events to support i.MX6SX net: fec: reset fep link status in suspend function net: sock: fix access via invalid file descriptor net: introduce helper macro for_each_cmsghdr ...
