| * ath6kl: Fix the byte alignment rule to avoid loss of bytes in a TCP segmentMyoungje Kim2013-03-182-5/+7
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Either first 3 bytes of the first received tcp segment or last one over MTU size file can be loss due to the byte alignment problem. Although ATH6KL_HTC_ALIGN_BYTES was defined for 'extra bytes for htc header alignment' in the patch "Fix buffer alignment for scatter-gather I/O"(1df94a857), there exists the bytes loss issue which means that it will be truncated 3 bytes in the transmitted file contents if a file which has over MTU size is transferred through TCP/IP stack. It doesn't look like TCP/IP stack bug of 3.5 or the latest version of kernel but the byte alignment issue. This patch is to use the roundup() function for the byte alignment rather than the predefined ATH6KL_HTC_ALIGN_BYTES. kvalo: fixed indentation Signed-off-by: Myoungje Kim <mjei78@gmail.com> Signed-off-by: Kalle Valo <kvalo@qca.qualcomm.com>
| * ath6kl: remove false check from ath6kl_rx()Kalle Valo2013-03-181-1/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Dan found a check from ath6kl_rx() which doesn't make any sense at all: " 1327 if (status || !(skb->data + HTC_HDR_LENGTH)) { ^^^^^^^^^^^^^^^^^^^^^^^^^^ skb->data is a pointer. This pointer math is always going to be false. Should it be testing "packet->act_len < HTC_HDR_LENGTH" or something?"

| * ath6kl: add tracing support to debug message macrosKalle Valo2013-03-182-4/+50
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Now all log messages are sent through the tracing infrastruture as well. Tracing point doesn't follow debug_mask module parameter, instead it sends all debug messages, so once you enable ath6kl_log_dbg tracing point you will get a lot of messages. Needs to be discussed if this is sensible or not. The overhead should be small enough and we anyway include debug level as well so it's easy to filter in user space. I wasn't really sure what to do with ath6kl_dbg_dump() and for now decided that it also sends the buffer to user space. But most likely in the future ath6kl_dbg_dump() should go away in favor of using proper tracing points, but we will see. Signed-off-by: Kalle Valo <kvalo@qca.qualcomm.com>

| * ath6kl: add tracing point for hif irqsKalle Valo2013-03-182-0/+23
| | | | | | | | | | | | | | | | | | Add a tracing point for hif irq and dump the register content to user space. This is in hif.c as we could use the same code also with SPI but, as ath6kl doesn't SPI and most likely never will be, this is used just by SDIO so name the trace point as ath6kl_sdio_irq to make it easier to manage filters.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The station change API isn't being checked properly before drivers are called, and as a result it is difficult to see what should be allowed and what not. In order to comprehensively check the API parameters parse everything first, and then have the driver call a function (cfg80211_check_station_change()) with the additionally information about the kind of station that is being changed; this allows the function to make better decisions than the old code could. While at it, also add a few checks, particularly in mesh and clarify the TDLS station lifetime in documentation. To be able to reduce a few checks, ignore any flag set bits when the mask isn't set, they shouldn't be applied then. Signed-off-by: Johannes Berg <johannes.berg@intel.com>

'ath6kl_hif_power_on' assigns 'ath6kl_recv_complete' as usb_complete_t/callback function for 'usb_fill_bulk_urb'. Thus the possibility of ar->htc_target being NULL via ath6kl_recv_complete -> ath6kl_usb_io_comp_work before even 'ath6kl_htc_create' is finished to initialize ar->htc_create. Worth noting is the obvious solution of doing 'ath6kl_hif_power_on' later(i.e after we are done with 'ath6kl_htc_create', causes a h/w bring up failure in AR6003 SDIO, as 'ath6kl_hif_power_on' is a pre-requisite to get the target version 'ath6kl_bmi_get_target_info'. So simply check for NULL pointer for 'ar->htc_target' and bail out.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Power Save Enabled : REC_POWER - conserve power without sacrificing performance. Power Save Disabled : MAX_PERF_POWER - maximum performance at the expense of power. Hence fix the debug message.

| |/ |/| | | | | | | | | | | | | | | | | | | | | | | | | | | | | The reg_notifier()'s return value need not be checked as it is only supposed to do post regulatory work and that should never fail. Any behaviour to regulatory that needs to be considered before cfg80211 does work to a driver should be specified by using the already existing flags, the reg_notifier() just does post processing should it find it needs to. Also make lbs_reg_notifier static. Signed-off-by: Luis R. Rodriguez <mcgrof@do-not-panic.com> [move lbs_reg_notifier to not break compile] Signed-off-by: Johannes Berg <johannes.berg@intel.com>

| * | nl80211/cfg80211: support VHT channel configurationJohannes Berg2012-11-261-6/+4
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Change nl80211 to support specifying a VHT (or HT) using the control channel frequency (as before) and new attributes for the channel width and first and second center frequency. The old channel type is of course still supported for HT. Also change the cfg80211 channel definition struct to support these by adding the relevant fields to it (and removing the _type field.) This also adds new helper functions: - cfg80211_chandef_create to create a channel def struct given the control channel and channel type, - cfg80211_chandef_identical to check if two channel definitions are identical - cfg80211_chandef_compatible to check if the given channel definitions are compatible, and return the wider of the two This isn't entirely complete, but that doesn't matter until we have a driver using it. In particular, it's missing - regulatory checks on the usable bandwidth (if that even makes sense) - regulatory TX power (database can't deal with it) - a proper channel compatibility calculation for the new channel types Signed-off-by: Johannes Berg <johannes.berg@intel.com>
| * | cfg80211: pass a channel definition structJohannes Berg2012-11-261-8/+14
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Instead of passing a channel pointer and channel type to all functions and driver methods, pass a new channel definition struct. Right now, this struct contains just the control channel and channel type, but for VHT this will change. Also, add a small inline cfg80211_get_chandef_type() so that drivers don't need to use the _type field of the new structure all the time, which will change.

| * | cfg80211: remove remain-on-channel channel typeJohannes Berg2012-11-262-8/+4
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | As mwifiex (and mac80211 in the software case) are the only drivers actually implementing remain-on-channel with channel type, userspace can't be relying on it. This is the case, as it's used only for P2P operations right now. Rather than adding a flag to tell userspace whether or not it can actually rely on it, simplify all the code by removing the ability to use different channel types. Leave only the validation of the attribute, so that if we extend it again later (with the needed capability flag), it can't break userspace sending invalid data.
