* libertas: remove some references to IW_MODE_abcHolger Schurig2009-10-27
| | | | | | | | | | | | | ... in pursue to quaff the wide-spread references to WEXT constants. When setting SNMP_MIB_OID_BSS_TYPE, wext.c can directly calculate the value the firmware wants. Reading of SNMP_MIB_OID_BSS_TYPE doesn't happen anywhere, so no need to convert the firmware value into WEXT values anyway.

* libertas: remove unused 11d codeHolger Schurig2009-10-27
| | | | | | | | | | | | | | Most of the 11d code was protected with an "if (priv->enable11d)" clause. But there was no code that anywhere that was able to set this variable to true. So all 11d code was dead for almost a year and no one complained. That's enought incentive to remove this code. Besides removing old cruft, we gain back the 11d capability in a common way when we merge the cfg80211 functionality.

* libertas: clean up and clarify get_common_ratesDan Williams2009-08-28
| | | | | | | | | | | | Clarify what the heck the function is doing with better variable names and less indirection and better comments. Also ensure callers use the proper minimum size, even though all rates arrays should be size MAX_RATES anyway. Reverts part of Andrey's dynamic alloc patch since we don't really need it.

| | | | | | | | | | | | | | | | | Check whether index is within bounds before testing the element. (also includes "Libertas: Association request to the driver failed" The size of the tmp buffer was too small, causing a regression rates->rates has an arraysize of 1, so a memcpy with MAX_RATES (14) was already causing reads out of bounds.

| * libertas: Read buffer overflowRoel Kluin2009-07-29
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Several arrays were read before checking whether the index was within bounds. ARRAY_SIZE() should be used to determine the size of arrays. rates->rates has an arraysize of 1, so calling get_common_rates() with a rates_size of MAX_RATES (14) was causing reads out of bounds. tmp_size can increment at most to (ARRAY_SIZE(lbs_bg_rates) - 1) * (*rates_size - 1), so that should be the number of elements of tmp[]. A goto can be eliminated: ret was already set upon its declaration. Signed-off-by: Roel Kluin <roel.kluin@gmail.com> Signed-off-by: John W. Linville <linville@tuxdriver.com>

* | libertas: copy WPA keys to priv when associatingAndrey Yurovsky2009-07-10
|/ | | | | | | | | | | | | | | | | | Libertas currently maintains a copy of the WPA unicast and group keys when using WPA or WPA2. This copy is checked when deciding whether or not to return to sleep in IEEE PS mode but the actual copying back to priv was omitted, which breaks IEEE PS mode with WPA/WPA2 when one issues commands that require temporarily keeping the device awake. This patch introduces the omitted copy-back of the keys so that IEEE PS functions correctly in WPA/WPA2 mode. Thanks to Dan Williams for clearing up the issue. V2: fix typo. Also, this has been tested on GSPI and SDIO with V9 firmware. Signed-off-by: Andrey Yurovsky <andrey@cozybit.com> Acked-by: Dan Williams <dcbw@redhat.com> Signed-off-by: John W.

Besides the "mechanical" convertion the patch add the following logical changes: * Removes the priv->logmsg variable, it was only used in one place anyway, also don't blindly get the counters when associating. Getting the counters then the user asks via WEXT for them is good enought. * don't set wstats.discard.fragment with log.rxfrag, because the latter is a counter for successfully received packets, not for fragmented packets.
