The IBM vNIC protocol provides support for the user to initiate a failover from the client LPAR in case the current backing infrastructure is deemed inadequate or in an error state. Support for two H_VIOCTL sub-commands for vNIC devices are required to implement this function. These commands are H_GET_SESSION_TOKEN and H_SESSION_ERR_DETECTED. "[H_GET_SESSION_TOKEN] is used to obtain a session token from a VNIC client adapter. This token is opaque to the caller and is intended to be used in tandem with the SESSION_ERROR_DETECTED vioctl subfunction." "[H_SESSION_ERR_DETECTED] is used to report that the currently active backing device for a VNIC client adapter is behaving poorly, and that the hypervisor should attempt to fail over to a different backing device, if one is available." To provide tools access to this functionality the vNIC driver creates a sysfs file that, when written to, will send a request to pHyp to failover to a different backing device. Signed-off-by:

On GOP port 0 two MAC modes are available: GMAC and XLG. The XLG MAC is used for 10G connectivity. This patch adds a basic 10G support by allowing to use the XLG MAC on port 0 and by reworking the port_enable/disable functions so that the XLG MAC is configured when using 10G. Signed-off-by:

The wifi driver can decide to not provide parts of the station info. For example, the expected throughput of the station can be omitted when the used rate control doesn't provide this kind of information. The B.A.T.M.A.N. V implementation must therefore check the filled bitfield before it tries to access the expected_throughput of the returned station_info. Reported-by:

The description of NL80211_CMD_ROAM indicated possibility for a request to roam issued by user-space. However, it also states that as not being implemented right now. This has been so since commit b23aa676 ("cfg80211: connect/disconnect API") added in 2009. So it seems safe to assume it will not be added any time soon and thus remove it. Signed-off-by:

Drivers that initiate roaming while being connected to a network that uses 802.1X authentication need to inform user space if 802.1X authentication is further required after roaming. For example, when using the Fast transition protocol, roaming within the mobility domain does not require new 802.1X authentication, but roaming to another mobility domain does. In addition, some drivers may not support 802.1X authentication (so it has to be done in user space), while other drivers do. Add a flag to the roaming notification to indicate if user space is required to do 802.1X authentication after the roaming or not. This flag will only be used for networks that use 802.1X authentication. For networks that do not use 802.1X authentication it is assumed that no further action is required from user space after the roaming notification. Signed-off-by:

Let drivers advertise support for station-mode 4-way handshake offloading with a new NL80211_EXT_FEATURE_4WAY_HANDSHAKE_STA_PSK flag. Extend use of NL80211_ATTR_PMK attribute indicating it might be passed as part of NL80211_CMD_CONNECT command, and contain the PSK (which is the PMK, hence the name.) The driver/device is assumed to handle the 4-way handshake by itself in this case (including key derivations, etc.), instead of relying on the supplicant.

Paolo Abeni says: ==================== udp: reduce cache pressure In the most common use case, many skb fields are not used by recvmsg(), and the few ones actually accessed lays on cold cachelines, which leads to several cache miss per packet. This patch series attempts to reduce such misses with different strategies: * caching the interesting fields in the scratched space * avoid accessing at all uninteresting fields * prefetching Tested using the udp_sink program by Jesper[1] as the receiver, an h/w l4 rx hash on the ingress nic, so that the number of ingress nic rx queues hit by the udp traffic could be controlled via ethtool -L. The udp_sink program was bound to the first idle cpu, to get more stable numbers.

when udp_recvmsg() is executed, on x86_64 and other archs, most skb fields are on cold cachelines. If the skb are linear and the kernel don't need to compute the udp csum, only a handful of skb fields are required by udp_recvmsg(). Since we already use skb->dev_scratch to cache hot data, and there are 32 bits unused on 64 bit archs, use such field to cache as much data as we can, and try to prefetch on dequeue the relevant fields that are left out. This can save up to 2 cache miss per packet. v1 -> v2: - changed udp_dev_scratch fields types to u{32,16} variant, replaced bitfiled with bool Signed-off-by:Paolo Abeni <pabeni@redhat.com> Acked-by:

Since UDP no more uses sk->destructor, we can clear completely the skb head state before enqueuing. Amend and use skb_release_head_state() for that. All head states share a single cacheline, which is not normally used/accesses on dequeue. We can avoid entirely accessing such cacheline implementing and using in the UDP code a specialized skb free helper which ignores the skb head state. This saves a cacheline miss at skb deallocation time. v1 -> v2: replaced secpath_reset() with skb_release_head_state() Signed-off-by:
