Since we now have IWAP handlers for all modes, we can combine them into one. Signed-off-by: NJohannes Berg <johannes@sipsolutions.net> Signed-off-by: NJohn W. Linville <linville@tuxdriver.com>

Until now we implemented iwfreq for managed mode, we needed to keep the implementations separate, but now that we have all versions implemented we can combine them and export just one handler.

This patch avoids memcpy from wdev->wext.ibss.bssid if it is NULL. This could happen if we SIOCGIWAP before SIOCSIWAP. Signed-off-by: NZhu Yi <yi.zhu@intel.com> Signed-off-by: NJohn W. Linville <linville@tuxdriver.com>

This reworks the key operation in cfg80211, and now only allows, from userspace, configuring keys (via nl80211) after the connection has been established (in managed mode), the IBSS been joined (in IBSS mode), at any time (in AP[_VLAN] modes) or never for all the other modes. In order to do shared key authentication correctly, it is now possible to give a WEP key to the AUTH command. To configure static WEP keys, these are given to the CONNECT or IBSS_JOIN command directly, for a userspace SME it is assumed it will configure it properly after the connection has been established. Since mac80211 used to check the default key in IBSS mode to see whether or not the network is protected, it needs an update in that area, as well as an update to make use of the WEP key passed to auth() for shared key authentication.

Over time, a lot of locking issues have crept into the smarts of cfg80211, so e.g. scan completion can race against a new scan, IBSS join can race against leaving an IBSS, etc. Introduce a new per-interface lock that protects most of the per-interface data that we need to keep track of, and sprinkle assertions about that lock everywhere. Some things now need to be offloaded to work structs so that we don't require being able to sleep in functions the drivers call. The exception to that are the MLME callbacks (rx_auth etc.) that currently only mac80211 calls because it was easier to do that there instead of in cfg80211, and future drivers implementing those calls will, if they ever exist, probably need to use a similar scheme like mac80211 anyway... In order to be able to handle _deauth and _disassoc properly, introduce a cookie passed to it that will determine locking requirements.

We shouldn't be looking at the ssid_len for non-IBSS, and for IBSS we should also return an error on trying to leave an IBSS while not in or joining an IBSS. This fixes an issue where we wouldn't disconnect() on an interface being taken down since there's no SSID configured this way.

In order to avoid problems with BSS structs going away while they're in use, I've long wanted to make cfg80211 keep track of them. Without the SME, that wasn't doable but now that we have the SME we can do this too. It can keep track of up to four separate authentications and one association, regardless of whether it's controlled by the cfg80211 SME or the userspace SME.

This variable isn't necessary -- the wext code keeps track of the BSSID itself, and otherwise we have current_bss. Signed-off-by: NJohannes Berg <johannes@sipsolutions.net> Signed-off-by: NJohn W. Linville <linville@tuxdriver.com>

When we leave an IBSS, we should clear the SSID and not just the BSSID, but since WEXT allows configuring while the interface is down we must not clear it when leaving due to taking the iface down, so some complications are needed.

Trying to separate header files into net/wireless.h and net/cfg80211.h has been a source of confusion. Remove net/wireless.h (because there also is the linux/wireless.h) and subsume everything into net/cfg80211.h -- except the definitions for regulatory structures which get moved to a new header net/regulatory.h. The "new" net/cfg80211.h is now divided into sections. There are no real changes in this patch but code shuffling and some very minor documentation fixes. I have also, to make things reflect reality, put in a copyright line for Luis to net/regulatory.h since that is probably exclusively written by him but was formerly in a file that only had my copyright line.

This adds IBSS API along with (preliminary) wext handlers. The wext handlers can only do IBSS so you need to call them from your own wext handlers if the mode is IBSS. The nl80211 API requires * an SSID * a channel (frequency) for the case that a new IBSS has to be created It optionally supports * a flag to fix the channel * a fixed BSSID The cfg80211 code also takes care to leave the IBSS before the netdev is set down. If wireless extensions are used, it also caches values when the interface is down and instructs the driver to join when the interface is set up.
