2015-08-20rt2x00: use DECLARE_EWMAJohannes Berg
Instead of using the out-of-line EWMA calculation, use DECLARE_EWMA() to create static inlines. On x86/64 this results in code that's one byte larger (for me), but reduces struct link_ant and struct link size by the two unsigned long values that store the parameters each.

rt2500usb_validate_eeprom() read data up to 0x6e (EEPROM_CALIBRATE_OFFSET) but only 0x6a bytes has been allocated and read from the eeprom. This lead to out-of-bound accesses and invalid values for EEPROM_BBPTUNE_R17 and EEPROM_CALIBRATE_OFFSET. Change the EEPROM_SIZE to 0x6e in order to retrieve all the fields.

2015-06-10mac80211: convert HW flags to unsigned long bitmapJohannes Berg
As we're running out of hardware capability flags pretty quickly, convert them to use the regular test_bit() style unsigned long bitmaps. This introduces a number of helper functions/macros to set and to test the bits, along with new debugfs code. The occurrences of an explicit __clear_bit() are intentional, the drivers were never supposed to change their supported bits on the fly. We should investigate changing this to be a per-frame flag.

2015-04-24mac80211: remove support for IFF_PROMISCJohannes Berg
This support is essentially useless as typically networks are encrypted, frames will be filtered by hardware, and rate scaling will be done with the intended recipient in mind.

2014-12-01Revert "rt2x00: Endless loop on hub port power down"Stanislaw Gruszka
This reverts commit 2ad69ac5976191e9bb7dc4044204a504653ad1bb. It causes wireless device disappear when we get -EPROTO error form USB request. I encounter such situation occasionally when resume form suspend with RT3070 adapter: [ 289.619985] ieee80211 phy0: rt2x00usb_vendor_request: Error - Vendor Request 0x06 failed for offset 0x0404 with error -71 [ 289.639368] ieee80211 phy0: rt2800_wait_bbp_ready: Error - BBP register access failed, aborting [ 289.639374] ieee80211 phy0: rt2800usb_set_device_state: Error - Device failed to enter state 4 (-5) Without the patch, except printing error, device works just fine after resume. Currently after timeouts and REGISTER_BUSY_COUNT tuning, we should not have any "endless loop", though we can wait quite long when driver is trying to communicate with the device through non functioning USB connection. Generally the problem that commit 2ad69ac597619 solves is kinda artificial. Cc: Richard Genoud <richard.genoud@gmail.com> Signed-off-by: Stanislaw Gruszka <sgruszka@redhat.com> Signed-off-by: John W.

2014-12-01rt2800: calculate tx power temperature compensation on selected chipsStanislaw Gruszka
Currently implemented temperature compensation is only valid on some of supported chips. Other chips do not need temperature compensation or need different way to do this (not yet implemented in the rt2800 driver). Trying to do run rt2800_get_gain_calibration_delta() when this is not appropriate on particular chip gives bogus result of TX power and can make connection unstable. This is follow up to commit 8c8d2017ba25c510ddf093419048460db1109bc4 "rt2800: fix RT5390 & RT3290 TX power settings regression". On that commit we avoid setting BBP_R1 register, but the real problem is wrong temperature compensation calculation.

2014-11-11rt2x00: do not align payload on modern H/WStanislaw Gruszka
RT2800 and newer hardware require padding between header and payload if header length is not multiple of 4. For historical reasons we also align payload to to 4 bytes boundary, but such alignment is not needed on modern H/W. Patch fixes skb_under_panic problems reported from time to time: https://bugzilla.kernel.org/show_bug.cgi?id=84911 https://bugzilla.kernel.org/show_bug.cgi?id=72471 http://marc.info/?l=linux-wireless&m=139108549530402&w=2 https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1087591 Panic happened because we eat 4 bytes of skb headroom on each (re)transmission when sending frame without the payload and the header length not being multiple of 4 (i.e. QoS header has 26 bytes). On such case because paylad_aling=2 is bigger than header_align=0 we increase header_align by 4 bytes. To prevent that we could change the check to: if (payload_length && payload_align > header_align) header_align += 4; but not aligning payload at all is more effective and alignment is not really needed by H/W (that has been tested on OpenWrt project for few years now).

2014-10-27rt2x00: tune multi-registers I/O timeoutStanislaw Gruszka
We provide timeout value to rt2x00usb_vendor_request_buff() based on number of registers to process. That value is passed down to rt2x00usb_vendor_req_buff_lock() and ends in usb_control_msg(). But we do not read/write all registers in rt2x00usb_vendor_req_buff_lock() at once. We read/write them in chunks of 64 bytes in the loop, hence passed timeout value to low level is too big. Patch removes timeout argument from rt2x00usb_vendor_request_buff() and use short REGISTER_TIMEOUT in rt2x00usb_vendor_req_buff_lock(). That timeout value should be fine for 64 bytes and smaller requests. For EEPROM read we introduced new timeout value equal to 2 seconds. Patch fixes process uninterruptible sleep stalls for long period, when USB bus has problem to satisfy a request and we wait very long time on usb_start_wait_urb().

2014-07-07rt2800usb: Don't perform DMA from stackAndrea Merello
Function rt2800usb_autorun_detect() passes the address of a variable allocated onto the stack to be used for DMA by the USB layer. This has been caught by my debugging-enabled kernel. This patch change things in order to allocate that variable via kmalloc, and it adjusts things to handle the kmalloc failure case, propagating the error.

As reported by Matthias, on 5572 chip, even if we clear up TXWI of corresponding beacon, hardware still try to send it or do other action that increase power consumption peak up to 1A. To avoid the issue, setup beaconing dynamically by configuring offsets of currently active beacons and MAC_BSSID_DW1_BSS_BCN_NUM variable, which limit number of beacons that hardware will try to send.

2014-06-17rt2x00: fix rfkill regression on rt2500pciStanislaw Gruszka
As reported by Niels, starting rfkill polling during device probe (commit e2bc7c5, generally sane change) broke rfkill on rt2500pci device. I considered that bug as some initalization issue, which should be fixed on rt2500pci specific code. But after several attempts (see bug report for details) we fail to find working solution. Hence I decided to revert to old behaviour on rt2500pci to fix regression. Additionally patch also unregister rfkill on device remove instead of ifconfig down, what was another issue introduced by bad commit. Bug report: https://bugzilla.kernel.org/show_bug.cgi?id=73821 Fixes: e2bc7c5f3cb8 ("rt2x00: Fix rfkill_polling register function.")

2014-06-17rt2800usb:fix hang during firmware loadMichael Braun
The device 057c:8501 (AVM Fritz! WLAN v2 rev. B) boots into a state that does not actually require loading a firmware file. The vendors driver finds out about this by checking a firmware state register, so this patch adds this here. Finally, with this patch applied, my wifi dongle actually becomes useful (scan + connect to wpa network works).

2014-06-17rt2800usb:fix efuse detectionMichael Braun
The device 057c:8501 (AVM Fritz! WLAN v2 rev. B) currently does not load. One thing observed is that the vendors driver detects EFUSE mode for this device, but rt2800usb does not. This is due to rt2800usb lacking a check for the firmware mode present in the vendors driver, that this patch adopts for rt2800usb. With this patch applied, the 'RF chipset' detection does no longer fail.
