2014-10-29mac802154: add IEEE802154_HW_ARET hw flagAlexander Aring
This patch adds a new IEEE802154_HW_ARET hardware flag for indicating that the transceiver supports ARET handling. Also remove the IEEE802154_HW_FRAME_RETRIES from IEEE802154_HW_CSMA flag. Frame retries handling is part of ARET. Signed-off-by: Alexander Aring <alex.aring@gmail.com> Signed-off-by: Marcel Holtmann <marcel@holtmann.org>

2014-10-29tcp: allow for bigger reordering levelEric Dumazet
While testing upcoming Yaogong patch (converting out of order queue into an RB tree), I hit the max reordering level of linux TCP stack. Reordering level was limited to 127 for no good reason, and some network setups [1] can easily reach this limit and get limited throughput. Allow a new max limit of 300, and add a sysctl to allow admins to even allow bigger (or lower) values if needed. [1] Aggregation of links, per packet load balancing, fabrics not doing deep packet inspections, alternative TCP congestion modules...

2014-10-28datapath: Rename last_action() as nla_is_last() and move to netlink.hSimon Horman
The original motivation for this change was to allow the helper to be used in files other than actions.c as part of work on an odp select group action. It was as pointed out by Thomas Graf that this helper would be best off living in netlink.h. Furthermore, I think that the generic nature of this helper means it is best off in netlink.h regardless of if it is used more than one .c file or not. Thus, I would like it considered independent of the work on an odp select group action.

Tasklets have much less overhead than workqueues. This patch also removes the heap allocation for the worker on receiving path. Like mac80211 we should prefer use a tasklet here instead a workqueue to getting fast out of interrupt context when ieee802154_rx_irqsafe is called by driver.

2014-10-25Bluetooth: Defer connection-parameter removal when unpairingAlfonso Acosta
Systematically removing the LE connection parameters and autoconnect action is inconvenient for rebonding without disconnecting from userland (i.e. unpairing followed by repairing without disconnecting). The parameters will be lost after unparing and userland needs to take care of book-keeping them and re-adding them. This patch allows userland to forget about parameter management when rebonding without disconnecting. It defers clearing the connection parameters when unparing without disconnecting, giving a chance of keeping the parameters if a repairing happens before the connection is closed.

2014-10-25Bluetooth: Include ADV_IND report in Device Connected eventAlfonso Acosta
There are scenarios when autoconnecting to a device after the reception of an ADV_IND report (action 0x02), in which userland might want to examine the report's contents. For instance, the Service Data might have changed and it would be useful to know ahead of time before starting any GATT procedures. Also, the ADV_IND may contain Manufacturer Specific data which would be lost if not propagated to userland. In fact, this patch results from the need to rebond with a device lacking persistent storage which notifies about losing its LTK in ADV_IND reports. This patch appends the ADV_IND report which triggered the autoconnection to the EIR Data in the Device Connected event.

2014-10-22mac80211: add WMM admission control supportJohannes Berg
Use the currently existing APIs between mac80211 and the low level driver to implement WMM admission control. The low level driver needs to report the media time used by each transmitted packet in ieee80211_tx_status. Based on that information, mac80211 will modify the QoS parameters of the admission controlled Access Category when the limit is reached. Once the original QoS parameters can be restored, mac80211 will do so. One issue with this approach is that management frames will also erroneously be downgraded, but the upside is that the implementation is simple. In the future, it can be extended to driver- or device-based implementations that are better.

2014-10-22cfg80211: make WMM TSPEC support flag an nl80211 feature flagJohannes Berg
During the review of the corresponding wpa_supplicant patches we noticed that the only way for it to detect that this functionality is supported currently is to check for the command support. This can be misleading though, as the command was also designed to, in the future, support pure 802.11 TSPECs. Expose the WMM-TSPEC feature flag to nl80211 so later we can also expose an 802.11-TSPEC feature flag (if needed) to differentiate the two cases. Note: this change isn't needed in 3.18 as there's no driver there yet that supports the functionality at all. Signed-off-by: Johannes Berg <johannes.berg@intel.com>

Pablo Neira Ayuso says: ==================== netfilter fixes for net The following patchset contains netfilter fixes for your net tree, they are: 1) Fix missing MODULE_LICENSE() in the new nf_reject_ipv{4,6} modules. 2) Restrict nat and masq expressions to the nat chain type. Otherwise, users may crash their kernel if they attach a nat/masq rule to a non nat chain. 3) Fix hook validation in nft_compat when non-base chains are used. Basically, initialize hook_mask to zero. 4) Make sure you use match/targets in nft_compat from the right chain type. The existing validation relies on the table name which can be avoided by 5) Better netlink attribute validation in nft_nat. This expression has to reject the configuration when no address and proto configurations are specified. 6) Interpret NFTA_NAT_REG_*_MAX if only if NFTA_NAT_REG_*_MIN is set. Yet another sanity check to reject incorrect configurations from userspace. 7) Conditional NAT attribute dumping depending on the existing configuration. ==================== Signed-off-by: David S.
