Make the DMAable mameory consistent with pci_set_consistent_dma_mask(). The DMA-mapping.txt Documentation recommends this but for PCI-X considerations and on strange architecture like SGI SN2, not sure why it would fix an issue but lets see if it does, just in case. Before this, this driver was tested with x86_64 with about 7 GB of RAM, not sure if this is really needed. Signed-off-by:

Use DMA_32BIT_MASK to clarify we only want 32-bit DMA memory. What was there before is also 32-bit but this makes it clearer Signed-off-by:

Instead of hardcoding the used in/out endpoints we should detect them by walking through all available endpoints. rt2800usb will gain the most out of this, because the legacy drivers indicate that there are multiple endpoints available. However this code might benefit at least rt73usb as well for the MIMO queues, and if we are really lucky rt2500usb will benefit because for the TX and PRIO queues. Even if rt2500usb and rt73usb do not get better performance after this patch, the endpoint detection still belongs to rt2x00usb, and it shouldn't hurt to always try to detect the available endpoints.

After considerable testing, the initial fears that the driver might damage some flavors of RTL8187B hardware seem to be groundless. Accordingly, the logged warning is removed. In addition, Kconfig is changed to remove the dependence on EXPERIMENTAL. Signed-off-by:

Realtek 8187B has a receive command queue to feedback beacon interrupt and transmitted packet status. Use it to feedback mac80211 about status of transmitted packets. Unfortunately in the course of testing I found that the sequence number reported by hardware includes entire sequence control in a 12 bit only field, so a workaround is done to check only lowest bits.

Add conf_tx callback and use it to configure tx queues of 8187L/8187B. Tested-by:

Herton Ronaldo Krzesinski authored
Hin-Tak Leung reported that after the change "rtl8187: add short slot handling for 8187B" his RTL8187B started to give low throughput on network transfers. Turns out that the SIFS setting used isn't ok, it doesn't look to be the real aSIFSTime, using the "magical" 0x22 value like on other 818x variants as the vendor does too fixes the issue. Tested-by:

Race condition causes RX buffers to be accessed even before it is initialized. The RX and TX buffers are initialized immediately after the hardware is registered with mac80211. The mac80211 start callback is ready to be fired once the device is registered for a case when the wpa_supplicant is also running at the same time. The same race condition is also possible for RKFILL registration as RFKILL init happens after the device registration with mac80211 and it is possible that rfkill_register would be called even before it is initialized.

This enables the custom firmware regulatory solution option on iwlwifi drivers. These devices are uncapable of mapping their EEPROM regulatory domain to a specific ISO / IEC alpha2. Although the new 11n devices (>= iwl 5000) have only 3 regultaory SKUs -- MOW, ABG (no N) and BG -- the older devices (3945 and 4965) have a more complex SKU arrangement and therefore its not practical to move this to the driver.

This adds API to cfg80211 to allow wireless drivers to inform us if their firmware can handle regulatory considerations *and* they cannot map these regulatory domains to an ISO / IEC 3166 alpha2. In these cases we skip the first regulatory hint instead of expecting the driver to build their own regulatory structure, providing us with an alpha2, or using the reg_notifier(). Signed-off-by:

This adds country IE parsing to mac80211 and enables its usage within the new regulatory infrastructure in cfg80211. We parse the country IEs only on management beacons for the BSSID you are associated to and disregard the IEs when the country and environment (indoor, outdoor, any) matches the already processed country IE. To avoid following misinformed or outdated APs we build and use a regulatory domain out of the intersection between what the AP provides us on the country IE and what CRDA is aware is allowed on the same country. A secondary device is allowed to follow only the same country IE as it make no sense for two devices on a system to be in two different countries. In the case the AP is using country IEs for an incorrect country the user may help compliance further by setting the regulatory domain before or after the IE is parsed and in that case another intersection will be performed. CONFIG_WIRELESS_OLD_REGULATORY is supported but requires CRDA present. Signed-off-by:

Lets remain consistent and mark rds with > NL80211_MAX_SUPP_REG_RULES number of reg rules as invalid in is_valid_rd(). Signed-off-by:

Luis R. Rodriguez authored
kobject_uevent_env() can return an error but it just tells us if the uvent was built/sent or not, it doesn't tell us anything about what happened in userspace, whether the udev rule was present nor does it tell us if CRDA was present or not. So remove the informative complaint about it assuming it will tell us such things. Note that you can determine if CRDA is present after loading cfg80211 by using: is_old_static_regdom(cfg80211_regdomain) but this doesn't account for possible user install after initial boot, and also for when the user uses the static EU regulatory domain.

When intersecting it is possible that set_regdom() was called with a regulatory domain which we'll only use as an aid to build a final regulatory domain. Signed-off-by:

Luis R. Rodriguez authored
So far the __set_regdom() code is pretty generic as the intersection case is fairly straight forward; this will however change when 802.11d support is added so lets separate intersection code for now in preparation for 802.11d support. This patch only has slight functional changes. Signed-off-by:

We have complete control over REGDOM_SET_BY_* enum passed down to __regulatory_hint() as such there is no need to account for unexpected REGDOM_SET_BY_*'s, lets just remove the switch statement as this code does not change and won't change even when we add 802.11d support.

The patch rewrites the mac80211 configure_filter handler to better mapping mac80211 filter flags to iwlwifi hardware filter flags. We now can support 5 mac80211 filter flags: FIF_OTHER_BSS, FIF_ALLMULTI, FIF_PROMISC_IN_BSS, FIF_BCN_PRBRESP_PROMISC and FIF_CONTROL. This patch also avoids reconnecting if the filter flags are changed when the STA is associated. Because rx_assoc is used when full rxon is not necessary. Signed-off-by:

The callback function write_tx_data() can only fail when our ENTRY_OWNER_DEVICE_DATA flag on a queue entry failed to determine the entry was not available and it is in fact still owned by the hardware. This means that if that function fails the queue must be stopped in mac80211. When rt2x00queue_get_queue() returns NULL in the TX path, it means mac80211 has passed us an invalid queue, although this should be impossible, it shouldn't hurt if we send mac80211 a signal to stop the queue either. Both issues can simply be resolved by removing their manual failure handler and making them use the failure path provided in rt2x00mac_tx(). Signed-off-by:

rt2500usb and rt73usb have different register word sizes, for that reason the register access wrappers were never moved into rt2x00usb. With rt2800usb on its way, we should favor the 32bit register access and move those wrappers into rt2x00usb. That saves duplicate code, since only rt2500usb will need the special 16bit wrappers.

All code which accessed indirect registers was similar in respect to the for-loop, the given timeout, etc. Move it into a seperate function, which for PCI drivers can be moved into rt2x00pci. This allows us to cleanup the cleanup the code further by removing the goto statementsand making the codepath look a bit nicer. Signed-off-by:
