* ath9k: fix per-packet tx power configurationLorenzo Bianconi2015-05-031-27/+25
| | | | | | | | | | Do not use ieee80211_vif pointer in ath_get_rate_txpower() since it has been overwritten by setup_frame_info() and it will result in a corrupted tx power configuration. Set per-packet tx power in setup_frame_info() according to current vif tx power. Signed-off-by: Lorenzo Bianconi <lorenzo.bianconi83@gmail.com> Signed-off-by: Kalle Valo <kvalo@codeaurora.org>

| * iwlwifi: mvm: don't power off the device between INIT and OPER firmwaresEran Harary2015-04-284-42/+51
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Our device needs two different firmwares: the INIT firmware and the operational (OPER) firmware. The first one is run when the driver loads and it returns calibrations results as well as the NVM. The second one implements the WiFi protocol. If the wlan interface is not brought up, the device is put to low power state: no firmware will be running. When the interface is brought up, we would run the OPER firmware only and reuse the results of the run of the INIT firmware when the driver was loaded. This is changing with this patch. We now run the INIT firmware every time mac80211 calls start(). The penalty for that is minimal since the INIT firwmare run fast. I now also avoid to power down the device between the INIT and OPER firmware on certains buses. The motivation for this change is that there are components on the device (MFUART) that are triggered by the INIT firmware and need the device to be powered up in order to keep running. Powering the device down between the INIT and OPER firmware would stop these components and prevent them from running again since they are triggered by the INIT firmware only. The new flow allows this and also allows to trigger these components again when the interface is brought up after it has been brought down.

| * iwlwifi: mvm: fix Tx Power firmware APIAvri Altman2015-04-194-15/+58
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The firmware doesn't relate the scan to a vif. The scan is run by a separate entity called auxiliary MAC (aka AUX MAC). This AUX MAC needs to get Tx power limitations that are not applied on a specific vif, but on the device as a whole. This can be implemented by using the minimum of all the values set by the user for all the MACs. But then we need to ignore the limitations that come from the AP or regulatory for a specific vif: a specific vif might have regulatory limitations because of the channel is works on. This limit is irrelevant for the AUX MAC. Use the new API from mac80211: the user_power_level in bss_conf to achieve this. Firmware -13.ucode has already moved to this API.

* | rtlwifi: rtl8192cu: Fix kernel deadlockLarry Finger2015-04-281-1/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The USB mini-driver in rtlwifi, which is used by rtl8192cu, issues a call to usb_control_msg() with a timeout value of 0. In some instances where the interface is shutting down, this infinite wait results in a CPU deadlock. A one second timeout fixes this problem without affecting any normal operations.

All from Eric Biederman. 7) Support L3 forwarding offloading in switches, from Scott Feldman. 8) Collapse the LOCAL and MAIN ipv4 FIB tables when possible, to speed up route lookups even further. From Alexander Duyck. 9) Many improvements and bug fixes to the rhashtable implementation, from Herbert Xu and Thomas Graf. In particular, in the case where an rhashtable user bulk adds a large number of items into an empty table, we expand the table much more sanely. 10) Don't make the tcp_metrics hash table per-namespace, from Eric Biederman. 11) Extend EBPF to access SKB fields, from Alexei Starovoitov. 12) Split out new connection request sockets so that they can be established in the main hash table. Much less false sharing since hash lookups go direct to the request sockets instead of having to go first to the listener then to the request socks hashed underneath. From Eric Dumazet. 13) Add async I/O support for crytpo AF_ALG sockets, from Tadeusz Struk. 14) Support stable privacy address generation for RFC7217 in IPV6. From Hannes Frederic Sowa. 15) Hash network namespace into IP frag IDs, also from Hannes Frederic Sowa. 16) Convert PTP get/set methods to use 64-bit time, from Richard Cochran. * git://git.kernel.org/pub/scm/linux/kernel/git/davem/net-next: (1816 commits) fm10k: Bump driver version to 0.15.2 fm10k: corrected VF multicast update fm10k: mbx_update_max_size does not drop all oversized messages fm10k: reset head instead of calling update_max_size fm10k: renamed mbx_tx_dropped to mbx_tx_oversized fm10k: update xcast mode before synchronizing multicast addresses fm10k: start service timer on probe fm10k: fix function header comment fm10k: comment next_vf_mbx flow fm10k: don't handle mailbox events in iov_event path and always process mailbox fm10k: use separate workqueue for fm10k driver fm10k: Set PF queues to unlimited bandwidth during virtualization fm10k: expose tx_timeout_count as an ethtool stat fm10k: only increment tx_timeout_count in Tx hang path fm10k: remove extraneous "Reset interface" message fm10k: separate PF only stats so that VF does not display them fm10k: use hw->mac.max_queues for stats fm10k: only show actual queues, not the maximum in hardware fm10k: allow creation of VLAN on default vid fm10k: fix unused warnings ...

But it should always be used when available, for the ifdown/up or RF-Kill/CT-Kill scenarios. While at it, fix a couple of bugs in the init-from-last-MCC flow. Return an error value when a current MCC is not found. Pass on the regdomain to cfg80211 only if it was changed and don't ignore the return value from the cfg80211-setter function.

In many cases, for example P2P ROC time events, this will happen if the time event is aborted, for example due to a higher priority time event. This is entirely normal and not worth warning about. In other cases, where we actually do act upon this, for example when trying to connect and this fails, we should instead warn as part of the disconnect operation. Change the code to do that, i.e. make the warning a debug message, and make it more prominent (an error) when we actually disconnect because of it. This also fixes confusion in the logs - the warning was mistaken for something that needed investigation, while in most cases it's just expected behaviour that occasionally some lower-priority time events would not complete fully.
