2012-08-06rt61pci: fix NULL pointer dereference in config_lna_gainStanislaw Gruszka
We can not pass NULL libconf->conf->channel to rt61pci_config() as it is dereferenced unconditionally in rt61pci_config_lna_gain() subroutine.

2012-07-12mac80211: add time synchronisation with BSS for assocJohannes Berg
Some drivers (iwlegacy, iwlwifi and rt2x00) today use the bss_conf.last_tsf value. By itself though that value is completely worthless since it may be ancient. What really is needed is synchronisation between some device time and the TSF. To clarify this, rename bss_conf.last_tsf to sync_tsf and add sync_device_ts which is obtained from rx_status which gets a new field device_timestamp for this purpose. This is intentionally not using the mactime field since that is used for other things and in IBSS is expected to sync with the IBSS's TSF which isn't necessarily true for the device timestamp. Also, since we have the information and it's useful even before the connection has been established, give all the timing details to the driver before authenticating.

2012-07-09rt2x00usb: fix indexes ordering on RX queue kickStanislaw Gruszka
On rt2x00_dmastart() we increase index specified by Q_INDEX and on rt2x00_dmadone() we increase index specified by Q_INDEX_DONE. So entries between Q_INDEX_DONE and Q_INDEX are those we currently process in the hardware. Entries between Q_INDEX and Q_INDEX_DONE are those we can submit to the hardware. According to that fix rt2x00usb_kick_queue(), as we need to submit RX entries that are not processed by the hardware. It worked before only for empty queue, otherwise was broken. Note that for TX queues indexes ordering are ok. We need to kick entries that have filled skb, but was not submitted to the hardware, i.e. started from Q_INDEX_DONE and have ENTRY_DATA_PENDING bit set. From practical standpoint this fixes RX queue stall, usually reproducible in AP mode, like for example reported here: https://bugzilla.redhat.com/show_bug.cgi?id=828824 Reported-and-tested-by: Franco Miceli <fmiceli@plan.ceibal.edu.uy> Reported-and-tested-by: Tom Horsley <horsley1953@gmail.com> Cc: stable@vger.kernel.org Signed-off-by: Stanislaw Gruszka <sgruszka@redhat.com> Signed-off-by: John W.

2012-05-18USB: Disable hub-initiated LPM for comms devices.Sarah Sharp
Hub-initiated LPM is not good for USB communications devices. Comms devices should be able to tell when their link can go into a lower power state, because they know when an incoming transmission is finished. Ideally, these devices would slam their links into a lower power state, using the device-initiated LPM, after finishing the last packet of their data transfer. If we enable the idle timeouts for the parent hubs to enable hub-initiated LPM, we will get a lot of useless LPM packets on the bus as the devices reject LPM transitions when they're in the middle of receiving data. Worse, some devices might blindly accept the hub-initiated LPM and power down their radios while they're in the middle of receiving a transmission. The Intel Windows folks are disabling hub-initiated LPM for all USB communications devices under a xHCI USB 3.0 host. In order to keep the Linux behavior as close as possible to Windows, we need to do the same in Linux. Set the disable_hub_initiated_lpm flag for for all USB communications drivers. I know there aren't currently any USB 3.0 devices that implement these class specifications, but we should be ready if they do.

2012-04-23rt2800: add chipset revision RT5390R supportAnisse Astier
About 70% of the chips with revision RT5390R initialize incorrectly, using the auxiliary antenna instead of the main one. The net result is that signal reception is very poor (no AP further than 1M). This chipset differs from RT5390 and RT5390F by its support of hardware antenna diversity. Therefore antenna selection should be done differently, by disabling software features and previously selected antenna. This changeset does just that, and makes all RT5390R work properly.

2012-04-17rt2x00: Don't let mac80211 send a BAR when an AMPDU subframe failsAndreas Hartmann
There are connection stalls or very poor throughputs with rt2800 hardware using 802.11n in AP mode since patch "mac80211: retry sending failed BAR frames later instead of tearing down aggr"[1][2]. Since rt2800 hardware is not able to correctly report the tx status of BAR frames, this patch removes as workaround the existing error handling on AP side, which lets mac80211 send a BAR when an AMPDU subframe fails. As a result, most wifi clients (aside from Intel STAs on Windows) instead will timeout now the reorder buffer and request the lost frame again. The correct solution would be, to tear down BA session on AP side. This patch was born on the basis of "[RFT] rt2x00: Tear down BA session on QoS frame failure"[3]. Thanks to Helmut Schaa for his support!

2012-03-15rt2x00: rt2800usb: rework txstatus codeStanislaw Gruszka
Currently we read tx status register after each urb data transfer. As callback procedure also trigger reading, that causing we have many "threads" of reading status. To prevent that introduce TX_STATUS_READING flags, and check if we are already in process of sequential reading TX_STA_FIFO, before requesting new reads. Change timer to hrtimer, that make TX_STA_FIFO overruns less possible. Use 200 us for initial timeout, and then reschedule in 100 us period, this values probably have to be tuned. Make changes on txdone work. Schedule it from rt2800usb_tx_sta_fifo_read_completed() callback when first valid status show up. Check in callback if tx status timeout happens, and schedule work on that condition too. That make possible to remove tx status timeout from generic watchdog. I moved that to rt2800usb. Loop in txdone work, that should prevent situation when we queue work, which is already processed, and after finish work is not rescheduled again.
