2016-09-12sis900: use IS_ENABLED() instead of checking for built-in or moduleJavier Martinez Canillas
The IS_ENABLED() macro checks if a Kconfig symbol has been enabled either built-in or as a module, use that macro instead of open coding the same. Using the macro makes the code more readable by helping abstract away some of the Kconfig built-in and module enable details.

2016-09-12mac80211: RX BA support for sta max_rx_aggregation_subframesMaxim Altshul
The ability to change the max_rx_aggregation frames is useful in cases of IOP. There exist some devices (latest mobile phones and some AP's) that tend to not respect a BA sessions maximum size (in Kbps). These devices won't respect the AMPDU size that was negotiated during association (even though they do respect the maximal number of packets). This violation is characterized by a valid number of packets in a single AMPDU. Even so, the total size will exceed the size negotiated during association. Eventually, this will cause some undefined behavior, which in turn causes the hw to drop packets, causing the throughput to plummet. This patch will make the subframe limitation to be held by each station, instead of being held only by hw.

2016-09-12cfg80211: Remove deprecated create_singlethread_workqueueBhaktipriya Shridhar
The workqueue "cfg80211_wq" is involved in cleanup, scan and event related works. It queues multiple work items &rdev->event_work, &rdev->dfs_update_channels_wk, &wiphy_to_rdev(request->wiphy)->scan_done_wk, &wiphy_to_rdev(wiphy)->sched_scan_results_wk, which require strict execution ordering. Hence, an ordered dedicated workqueue has been used. Since it's a wireless driver, WQ_MEM_RECLAIM has been set to ensure forward progress under memory pressure.

2016-09-10Merge branch 'vrf-tx-hook'David S. Miller
David Ahern says: ==================== net: Convert vrf to tx hook The motivation for this series is that ICMP Unreachable - Fragmentation Needed packets are not handled properly for VRFs. Specifically, the FIB lookup in __ip_rt_update_pmtu fails so no nexthop exception is created with the reduced MTU. As a result connections stall if packets larger than the smallest MTU in the path are generated. While investigating that problem I also noticed that the MSS for all connections in a VRF is based on the VRF device's MTU and not the route the packets ultimately go through. VRF currently uses a dst to direct packets to the device. The first FIB lookup returns this dst and then the lookup in the VRF driver gets the actual output route. A side effect of this design is that the VRF dst is cached on sockets and then used for calculations like the MSS. This series fixes this problem by removing the hook in the FIB lookups that returns the dst pointing to the VRF device to the VRF and always doing the actual FIB lookup. This allows the real dst to be used throughout the stack (for example the MSS). Packets are diverted to the VRF device on Tx using an l3mdev hook in the output path similar to to what is done for Rx. The end result is a simpler implementation for VRF with fewer intrusions into the network stack and symmetrical packet handling for Rx and Tx paths. Comparison of netperf performance for a build without l3mdev (best case performance), the old vrf driver and the VRF driver from this series. Data are collected using VMs with virtio + vhost. The netperf client runs in the VM and netserver runs in the host. 1-byte RR tests are done as these packets exaggerate the performance hit due to the extra lookups done for l3mdev and VRF. Command: netperf -cC -H ${ip} -l 60 -t {TCP,UDP}_RR [-J red] TCP_RR UDP_RR IPv4 IPv6 IPv4 IPv6 no l3mdev 29,996 30,601 31,638 24,336 vrf old 27,417 27,626 29,159 24,801 vrf new 28,036 28,372 30,110 24,857 l3mdev, no vrf 29,534 30,465 30,670 24,346 * Transactions per second as reported by netperf * netperf modified to take a bind-to-device argument -- the -J red option 1. 'no l3mdev' == NET_L3_MASTER_DEV is unset so code is compiled out 2. 'vrf old' == data for existing implementation 3. 'vrf new' == data with this series 4. 'l3mdev, no vrf' == NET_L3_MASTER_DEV is enabled but traffic is not going through a VRF About the series - patch 1 adds the flow update (changing oif or iif to L3 master device and setting the flag to skip the oif check) to ipv4 and ipv6 paths just before hitting the rules. This catches all code paths in a single spot. - patch 2 adds the Tx hook to push the packet to the l3mdev if relevant - patch 3 adds some checks so the vrf device can act as a vrf-local loopback. These changes were not needed before since the vrf dst was returned from the lookup. - patches 4 and 5 flip the ipv4 and ipv6 stacks to the tx hook leaving the route lookup to be the real one. The dst flip happens at the beginning of the L3 output path so the VRFs can have device based features such as netfilter, tc and tcpdump. - patches 6-11 remove no longer needed l3mdev code v2 - properly handle IPv6 link scope addresses - keep the device xmit path and associated dst which is switched in by the l3_out hook. packets still need to go through the xmit path in case the user puts a qdisc on the vrf device and to allow tc rules. version 1 short circuited the tx handling and only covered netfilter and tcpdump. ==================== Signed-off-by: David S.

Instead, the dst on the skb is switched at the beginning of the IPv6 output processing to send the packet to the VRF driver on xmit. Link scope addresses (linklocal and multicast) need special handling: specifically the oif the flow struct can not be changed because we want the lookup tied to the enslaved interface. ie., the source address and the returned route MUST point to the interface scope passed in.

2016-09-10net: flow: Add l3mdev flow updateDavid Ahern
Add l3mdev hook to set FLOWI_FLAG_SKIP_NH_OIF flag and update oif/iif in flow struct if its oif or iif points to a device enslaved to an L3 Master device. Only 1 needs to be converted to match the l3mdev FIB rule. This moves the flow adjustment for l3mdev to a single point catching all lookups. It is redundant for existing hooks (those are removed in later patches) but is needed for missed lookups such as PMTU updates.

2016-09-10ATM-ZeitNet: Replace one kzalloc() call by kcalloc()Markus Elfring
* The script "checkpatch.pl" can point information out like the following. WARNING: Prefer kcalloc over kzalloc with multiply Thus fix the affected source code place. * Replace the specification of a data type by a pointer dereference to make the corresponding size determination a bit safer according to the Linux coding style convention. * Delete the local variable "size" which became unnecessary with this refactoring.

2016-09-10ATM-ZeitNet: Improve a size determination in zatm_open()Markus Elfring
Replace the specification of a data structure by a pointer dereference as the parameter for the operator "sizeof" to make the corresponding size determination a bit safer according to the Linux coding style convention.

2016-09-10ATM-ZeitNet: Use kmalloc_array() in start_tx()Markus Elfring
* A multiplication for the size determination of a memory allocation indicated that an array data structure should be processed. Thus use the corresponding function "kmalloc_array". This issue was detected by using the Coccinelle software. * Replace the specification of a data type by a pointer dereference to make the corresponding size determination a bit safer according to the Linux coding style convention.

2016-09-10ATM-nicstar: Refactor a dev_alloc_skb() call in dequeue_rx()Markus Elfring
The script "checkpatch.pl" can point out that assignments should usually not be performed within condition checks. Thus move an assignment for a local variable to a separate statement in this function. Signed-off-by: Markus Elfring <elfring@users.sourceforge.net> Signed-off-by: David S.
