| * wext: fix potential private ioctl memory content leakJohannes Berg2010-09-201-1/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | When a driver doesn't fill the entire buffer, old heap contents may remain, and if it also doesn't update the length properly, this old heap content will be copied back to userspace. It is very unlikely that this happens in any of the drivers using private ioctls since it would show up as junk being reported by iwpriv, but it seems better to be safe here, so use kzalloc.

| * wireless extensions: fix kernel heap content leakJohannes Berg2010-08-302-0/+19
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Wireless extensions have an unfortunate, undocumented requirement which requires drivers to always fill iwp->length when returning a successful status. When a driver doesn't do this, it leads to a kernel heap content leak when userspace offers a larger buffer than would have been necessary. Arguably, this is a driver bug, as it should, if it returns 0, fill iwp->length, even if it separately indicated that the buffer contents was not valid. However, we can also at least avoid the memory content leak if the driver doesn't do this by setting the iwp length to max_tokens, which then reflects how big the buffer is that the driver may fill, regardless of how big the userspace buffer is. To illustrate the point, this patch also fixes a corresponding cfg80211 bug (since this requirement isn't documented nor was ever pointed out by anyone during code review, I don't trust all drivers nor all cfg80211 handlers to implement it correctly).

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Some vendor specified mechanisms for 802.1X-style functionality use a different protocol than EAP (even if EAP is vendor-extensible).

* | | | | wireless: only use alpha2 regulatory information from country IEJohn W. Linville2010-07-201-613/+12
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The meaning and/or usage of the country IE is somewhat poorly defined. In practice, this means that regulatory rulesets in a country IE are often incomplete and might be untrustworthy. This removes the code associated with interpreting those rulesets while preserving respect for country "alpha2" codes also contained in the country IE. Signed-off-by: John W.

* | | | | cfg80211: don't get expired BSSesJohannes Berg2010-07-141-0/+5

This leads to inconsistencies and problems. Fix it by making cfg80211_get_bss() ignore BSSes that cfg80211_bss_expire() would remove.

* | | | cfg80211: ignore spurious deauthJohannes Berg2010-07-121-4/+4

Instead of warning and reporting the deauthentication to userspace, cfg80211 must simply ignore it so that spurious deauthentications, e.g. before starting authentication, aren't seen by userspace as actual deauthentications.

* | | nl80211: Add option to adjust transmit powerJuuso Oikarinen2010-06-241-0/+31
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This patch adds transmit power setting type and transmit power level attributes to NL80211_CMD_SET_WIPHY in order to facilitate adjusting of the transmit power level of the device. The added attributes allow selection of automatic, limited or fixed transmit power level, with the level definable in signed mBm format.

* | | cfg80211/mac80211: Update set_tx_power to use mBm instead of dBm unitsJuuso Oikarinen2010-06-241-5/+5
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | In preparation for a TX power setting interface in the nl80211, change the .set_tx_power function to use mBm units instead of dBm for greater accuracy and smaller power levels. Also, already in advance move the tx_power_setting enumeration to nl80211. This change affects the .tx_set_power function prototype. As a result, the corresponding changes are needed to modules using it. These are mac80211, iwmc3200wifi and rndis_wlan.
