2017-01-02Merge branch 'mlx5-odp'David S. Miller
Saeed Mahameed says: ==================== Mellanox mlx5 core and ODP updates 2017-01-01 The following eleven patches mainly come from Artemy Kovalyov who expanded mlx5 on-demand-paging (ODP) support. In addition there are three cleanup patches which don't change any functionality, but are needed to align codebase prior accepting other patches. Memory region (MR) in IB can be huge and ODP (on-demand paging) technique allows to use unpinned memory, which can be consumed and released on demand. This allows to applications do not pin down the underlying physical pages of the address space, and save from them need to track the validity of the mappings. Rather, the HCA requests the latest translations from the OS when pages are not present, and the OS invalidates translations which are no longer valid due to either non-present pages or mapping changes. In existing ODP implementation applications is needed to register memory buffers for communication, though registered memory regions need not have valid mappings at registration time. This patch set performs the following steps to expand current ODP implementation: 1. It refactors UMR to support large regions, by introducing generic function to perform HCA translation table modifications. This function supports both atomic and process contexts and is not limited by number of modified entries. This function allows to enable reallocated memory regions of arbitrary size, so adding MR cache buckets to support up to 16GB MRs. 2. It changes page fault event format and refactor page faults logic together with addition of atomic support. 3. It prepares mlx5 core code to support implicit registration with simplified and relaxed semantics. Implicit ODP semantics allows to applications provide special memory key that represents their complete address space. Thus all IO accesses referencing to this key (with proper access rights associated with the key) wouldn't need not register any virtual address range. Thanks, Artemy, Ilya and Leon v1->v2: - Don't use 'inline' in .c files ==================== Signed-off-by: David S. Miller <davem@davemloft.net>

2017-01-02igmp: Make igmp group member RFC 3376 compliantMichal Tesar
5.2. Action on Reception of a Query When a system receives a Query, it does not respond immediately. Instead, it delays its response by a random amount of time, bounded by the Max Resp Time value derived from the Max Resp Code in the received Query message. A system may receive a variety of Queries on different interfaces and of different kinds (e.g., General Queries, Group-Specific Queries, and Group-and-Source-Specific Queries), each of which may require its own delayed response. Before scheduling a response to a Query, the system must first consider previously scheduled pending responses and in many cases schedule a combined response. Therefore, the system must be able to maintain the following state: o A timer per interface for scheduling responses to General Queries. o A per-group and interface timer for scheduling responses to Group- Specific and Group-and-Source-Specific Queries. o A per-group and interface list of sources to be reported in the response to a Group-and-Source-Specific Query. When a new Query with the Router-Alert option arrives on an interface, provided the system has state to report, a delay for a response is randomly selected in the range (0, [Max Resp Time]) where Max Resp Time is derived from Max Resp Code in the received Query message. The following rules are then used to determine if a Report needs to be scheduled and the type of Report to schedule. The rules are considered in order and only the first matching rule is applied. 1. If there is a pending response to a previous General Query scheduled sooner than the selected delay, no additional response needs to be scheduled. 2. If the received Query is a General Query, the interface timer is used to schedule a response to the General Query after the selected delay. Any previously pending response to a General Query is canceled. --8<-- Currently the timer is rearmed with new random expiration time for every incoming query regardless of possibly already pending report. Which is not aligned with the above RFE. It also might happen that higher rate of incoming queries can postpone the report after the expiration time of the first query causing group membership loss. Now the per interface general query timer is rearmed only when there is no pending report already scheduled on that interface or the newly selected expiration time is before the already pending scheduled report.

For core revision 3.x Address-Aligned Beats is available in two registers. The DT property snps,aal was created for AAL in the DMA bus register, which is a read/write bit. The DT property snps,axi_all was created for AXI_AAL in the AXI bus mode register, which is a read only bit that reflects the value of AAL in the DMA bus register. Since the value of snps,axi_all is never used in the driver, and since the property was created for a bit that is read only, it should be safe to remove the property.

2017-01-02clean_bdev_aliases: Prevent cleaning blocks that are not in block rangeChandan Rajendra
The first block to be cleaned may start at a non-zero page offset. In such a scenario clean_bdev_aliases() will end up cleaning blocks that do not fall in the range of blocks to be cleaned. This commit fixes the issue by skipping blocks that do not fall in valid block range.

2017-01-02HID: sensor-hub: Move the memset to sensor_hub_get_feature()Srinivas Pandruvada
While applying patch d443a0aa3a29: "HID: hid-sensor-hub: clear memory to avoid random data", there was some issues in applying correct version of the patch. This resulted in the breakage of sensor functions as all request like power-up will be reset by the memset() in the function sensor_hub_set_feature(). The reset of caller buffer should be in the function sensor_hub_get_feature(), not in the sensor_hub_set_feature().

The DolphinBar by Mayflash (identified as Dragonrise) needs HID_QUIRK_MULTI_INPUT to split it up into four input devices. Without this quirk the adapter is falsely recognized as a tablet.

2017-01-02mac80211: initialize fast-xmit 'info' laterJohannes Berg
In ieee80211_xmit_fast(), 'info' is initialized to point to the skb that's passed in, but that skb may later be replaced by a clone (if it was shared), leading to an invalid pointer. This can lead to use-after-free and also later crashes since the real SKB's info->hw_queue doesn't get initialized properly. Fix this by assigning info only later, when it's needed, after the skb replacement (may have) happened.

2017-01-01Merge branch 'l2tp-socket-lookup-fixes'David S. Miller
Guillaume Nault says: ==================== l2tp: socket lookup fixes for l2tp_ip and l2tp_ip6 There are still some cases that aren't correctly handled in the socket lookup functions of l2tp_ip and l2tp_ip6. This series fixes lookups for connected sockets and for sockets bound to the IPv6 unspecified address. bind() and connect() should now work as expected on IPPROTO_L2TP sockets. Extra features, like SO_REUSEADDR, remain unsupported. The matching conditions in __l2tp_ip6_bind_lookup() and __l2tp_ip_bind_lookup() are getting hard to read. I've kept the single test approach to make the intend of the patches clear. I'll split the conditionals once these fixes reach net-next. ==================== Signed-off-by: David S.

2017-01-01l2tp: take remote address into account in l2tp_ip and l2tp_ip6 socket lookupsGuillaume Nault
For connected sockets, __l2tp_ip{,6}_bind_lookup() needs to check the remote IP when looking for a matching socket. Otherwise a connected socket can receive traffic not originating from its peer. Drop l2tp_ip_bind_lookup() and l2tp_ip6_bind_lookup() instead of updating their prototype, as these functions aren't used.

2017-01-01l2tp: consider '::' as wildcard address in l2tp_ip6 socket lookupGuillaume Nault
An L2TP socket bound to the unspecified address should match with any address. If not, it can't receive any packet and __l2tp_ip6_bind_lookup() can't prevent another socket from binding on the same device/tunnel ID. While there, rename the 'addr' variable to 'sk_laddr' (local addr), to make following patch clearer. Signed-off-by: Guillaume Nault <g.nault@alphalink.fr> Signed-off-by: David S.
