2016-11-25cxgb4: fix memory leak on txq_infoColin Ian King1-1/+1
Currently if txq_info->uldtxq cannot be allocated then txq_info->txq is being kfree'd (which is redundant because it is NULL) instead of txq_info. Fix this by instead kfree'ing txq_info. Signed-off-by: Colin Ian King <[email protected]> Signed-off-by: David S. Miller <[email protected]>

The report is valid: doing the math in this function, with an input value N=63 the variable s16tableIndex gets a value of 31. This value is used as an index in the array log_table with 32 entries. But the next line is: s16errorApproximation = (s16) qm_mulu16(u16offset, (u16) (log_table[s16tableIndex + 1] - log_table[s16tableIndex])); With s16tableIndex + 1 we are trying an out-of-bounds access to the array. The log_table array provides log2 values in q.15 format and the above statement tries an error approximation with the next value. To fix this issue add the next value to the array and update the comment accordingly. Signed-off-by: Tobias Regnery <[email protected]> Signed-off-by: Kalle Valo <[email protected]>

In order to obtain retry count for a given rate we need to pass the full struct ieee80211_tx_info to the function setting the rate in he TX descriptor. This uncovered a huge bug where the old code would use struct ieee80211_rate.flags to test for rate parameters, which is always zero, instead of the flags value from struct ieee80211_tx_rate.

2016-11-25rtl8xxxu: Fix rtl8192eu driver reload issueJes Sorensen1-1/+7
The 8192eu suffered from two issues when reloading the driver. The same problems as with the 8723bu where REG_RX_WAIT_CCA bits 22 and 23 didn't get set in rtl8192e_enable_rf(). In addition it also seems prone to issues when setting REG_RF_CTRL to 0 intead of just disabling the RF_ENABLE bit. Similar to what was causing issues with the 8188eu.

2016-11-24ethtool: Protect {get, set}_phy_tunable with PHY device mutexFlorian Fainelli1-11/+5
PHY drivers should be able to rely on the caller of {get,set}_tunable to have acquired the PHY device mutex, in order to both serialize against concurrent calls of these functions, but also against PHY state machine changes. All ethtool PHY-level functions do this, except {get,set}_tunable, so we make them consistent here as well.

2016-11-23ath10k: fix monitor vdev for receiving other bss framesManoharan, Rajkumar3-1/+11
In order to receive other BSS entries in mesh mode, Monitor vdev is created whenever filter flag is set with OTHER_BSS. Recently it is root caused that setting promisc filter for Mesh interface is causing performance and stability issues. To fix this issue, firmware will configure appropriate rxfilters by default for mesh vdev during vdev creation. This change fixes monitor vdev creation based on firmware IE Signed-off-by: Rajkumar Manoharan <[email protected]> Signed-off-by: Kalle Valo <[email protected]>
2016-11-23ath10k: add support for per sta tx bitrateAnilkumar Kolli1-0/+13
Per STA tx bitrate info is filled from peer stats. Export per sta txrate info to cfg80211/nl80211 Signed-off-by: Anilkumar Kolli <[email protected]> Signed-off-by: Kalle Valo <[email protected]>
2016-11-23ath10k: add per peer htt tx stats support for 10.4Anilkumar Kolli5-1/+178
Per peer tx stats are part of 'HTT_10_4_T2H_MSG_TYPE_PEER_STATS' event, Firmware sends one HTT event for every four PPDUs. HTT payload has success pkts/bytes, failed pkts/bytes, retry pkts/bytes and rate info per ppdu. Peer stats are enabled through 'WMI_SERVICE_PEER_STATS', which are nowadays enabled by default. Parse peer stats and update the tx rate information per STA. tx rate, Peer stats are tested on QCA4019 with Firmware version 10.4-3.2.1-00028.

Use RTS/CTS protection for TXOP on all rates modes as default and disable CCK rates (this cause performance problems). Signed-off-by: Stanislaw Gruszka <[email protected]> Signed-off-by: Kalle Valo <[email protected]>
2016-11-23rt2800: use RTS/CTS protection instead of CTS-to-selfStanislaw Gruszka1-3/+3
Change default to RTS/CTS protection. This has a cost of transmitting one more control frame (RTS) however protect us from traffic from hidden node. On station mode will use CTS-to-self if AP will configure that for the network. Signed-off-by: Stanislaw Gruszka <[email protected]> Signed-off-by: Kalle Valo <[email protected]>

2016-11-23rt2800: do not overwrite WPDMA_GLO_CFG_WP_DMA_BURST_SIZEStanislaw Gruszka1-1/+0
We already initlized WPDMA_GLO_CFG_WP_DMA_BURST_SIZE to 3 on rt2800_init_registers() for USB devices. For PCI devices we will use HW default setting, which is 2, so patch does not change behaviour on PCI devices.

We should not reset USB_DMA_CFG on rt2800usb_init_registers() as this function is called indirectly from rt2800_enable_radio().
