Linville says: ==================== pull request: wireless 2014-09-11 Please pull this batch of fixes intended for the 3.17 stream: For the mac80211 bits, Johannes says: "Two more fixes for mac80211 - one of them addresses a long-standing issue that we only found when using vendor events more frequently; the other addresses some bad information being reported in userspace that people were starting to actually look at." For the iwlwifi bits, Emmanuel says: "I re-enable scheduled scan on firmware that contain the fix for the bug that Linus reported. A few trivial fixes: endianity issues, the same DTIM period fix that I did in mac80211. Eyal fixes a few issues we identified with EAPOL, we now send them just as if they were management frames, this solves interrop issues. Johannes has another set of trivial fixes, while Luca fixes the way we configure the filters in the firmware. Last but not least, a new device is added by Oren." Emmanuel was traveling, resulting in his pull to be a bit larger than I would have liked to see at this point. FWIW, I have asked Emmanuel to be much more strict for any more pull requests in this cycle. In addition to the above, Sujith Manoharan reverts an earlier ath9k patch. The earlier change was found to allow for the device to sleep too long and miss beacons. ==================== Signed-off-by: David S. Miller <davem@davemloft.net>

2014-09-12net: arc_emac: prevent reuse of unreclaimed tx descriptorsBeniamino Galvani

2014-09-12net: arc_emac: enable tx interruptsBeniamino Galvani
In the current implementation the cleaning of tx ring is done by the NAPI poll handler, which is scheduled after rx interrupts. Thus, in absence of received packets the reclaim of used tx buffers is never executed, blocking further transmission. This can be easily reproduced starting the transmission of a UDP flow with iperf, which blocks almost immediately because skbs are not returned to the stack and the socket send buffer becomes full. The patch enables tx interrupts so that the tx reclaim is scheduled after completed transmissions.

2014-09-11Revert "ath9k: Calculate sleep duration"Sujith Manoharan
This reverts commit 09ebb810927a110e4c354beb20308830d108a54b. ath9k_hw_set_sta_beacon_timers() configures AR_TIM_PERIOD with the beacon interval. Before this commit, the sleepduration was never greater than the beacon interval. But now, the behavior has changed. For example, with an AP that uses a beacon interval of 100: ath: phy9: next beacon 61128704 ath: phy9: beacon period 204800 ath: phy9: DTIM period 204800 If the sleepduration is calculated based on the listen time, then the bmiss threshold should also be changed since the HW would be in sleep state for a longer time, but that is not done currently. To avoid configuring a higher beacon interval based on the sleepduration, revert to the original behavior. Power consumption is not a problem since PS is disabled in ath9k anyway.

2014-09-08sunvnet - add missing rmb() for sunvnet driverDavid L Stevens
The sunvnet driver does not have an rmb() in the ring consumer corresponding to the wmb() in the producer. According to Documentation/memory-barriers.txt: "When dealing with CPU-CPU interactions, certain types of memory barrier should always be paired. A lack of appropriate pairing is almost certainly an error." In cases where an rmb() is not a no-op and a consumer is removing data from the ring while a producer is adding new entries, a load reorder would allow CPU1 CPU2 ---- ---- LOAD desc.size [e.g] STORE desc.size <wmb> set desc.hdr.state = VIO_DESC_READY LOAD desc.hdr.state [because VIO_DESC_READY, use old desc.size, already loaded out of order] [CPU2 has reordered apparently unrelated LOADs] To ensure other desc fields are not loaded before checking VIO_DESC_READY, we need an rmb() between the check and desc data accesses. I've also moved the viodbg() call to after the rmb() so that it, too, has current descriptor data even with reordering, which has the side effect that it won't print anything for descriptors that are not VIO_DESC_READY as before. That's a) probably a good thing, since the fields are not necessarily set and, b) better than adding another rmb() just for viodbg(). This would not be possible if strict-ordering is enforced, but then the memory barriers should be no-ops in that case.

It's better to avoid sending EAPOLs in high rates as it reduces the chances of a successful 4-Way handshake.

2014-09-06amd-xgbe: Enable interrupts for all management countersLendacky, Thomas
As the management counters reach a threshold they will generate an interrupt so the value can be saved and the counter reset. The current code does not enable this interrupt on all counters. This can result in inaccurate statistics. Update the code to enable all the counters to generate an interrupt when its threshold is exceeded.

2014-09-06amd-xgbe: Treat certain counter registers as 64 bitLendacky, Thomas
Even if the management counters are configured to be 32 bit register values, the [rt]xoctetcount_gb and [rt]xoctetcount_g counters are always 64 bit counter registers. Since they are not being treated as 64 bit values, these statistics are being reported incorrectly (ifconfig, ethtool, etc.). Update the routines used to read the registers to access the "hi" register (an offset of 4 from the "lo" register) to create a 64 bit value for these 64 bit counters.

2014-09-06greth: moved TX ring cleaning to NAPI rx poll funcDaniel Hellstrom
This patch does not affect the 10/100 GRETH MAC. Before all GBit GRETH TX descriptor ring cleaning was done in start_xmit(), when descriptor list became full it activated TX interrupt to start the NAPI rx poll function to do TX ring cleaning. With this patch the TX descriptor ring is always cleaned from the NAPI rx poll function, triggered via TX or RX interrupt. Otherwise we could end up in TX frames being sent but not reported to the stack being sent. On the 10/100 GRETH this is not an issue since the SKB is copied&aligned into private buffers so that the SKB can be freed directly on start_xmit() Signed-off-by: Daniel Hellstrom <daniel@gaisler.com> Signed-off-by: David S.

SATA host controller driver. Due to HW errata the APM X-Gene AHCI SATA host controller reports link down even if the device presence is detected. This issue is due to speed negotiation failure. This patch implements the algorithm to retry the COMRESET if PxSTAT register reports device presence detected but PHY communication not established. The maximum retry attempts are 3. This patch also fixes the code to match the algorithm for the printing a warning message if the disparity error still exists after link up.

It seems on 32 bit kernels page_address() can reutrn a NULL value in some circumstances, and the pci_map_single api isn't prepared to handle that (on this system it results in a bogus pointer deference in nommu_map_page. The fix is pretty easy, if we convert the 3c59x driver to use the more convieient skb_frag_dma_map api we don't need to find the virtual address of the page at all, and page gets mapped to the hardware properly.
