2010-09-20wext: fix potential private ioctl memory content leakJohannes Berg
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.

2010-08-30wireless extensions: fix kernel heap content leakJohannes Berg
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).

2010-05-07cfg80211/mac80211: better channel handlingJohannes Berg
Currently (all tested with hwsim) you can do stupid things like setting up an AP on a certain channel, then adding another virtual interface and making that associate on another channel -- this will make the beaconing to move channel but obviously without the necessary IEs data update. In order to improve this situation, first make the configuration APIs (cfg80211 and nl80211) aware of multi-channel operation -- we'll eventually need that in the future anyway. There's one userland API change and one API addition. The API change is that now SET_WIPHY must be called with virtual interface index rather than only wiphy index in order to take effect for that interface -- luckily all current users (hostapd) do that. For monitor interfaces, the old setting is preserved, but monitors are always slaved to other devices anyway so no guarantees. The second userland API change is the introduction of a per virtual interface SET_CHANNEL command, that hostapd should use going forward to make it easier to understand what's going on (it can automatically detect a kernel with this command). Other than mac80211, no existing cfg80211 drivers are affected by this change because they only allow a single virtual interface. mac80211, however, now needs to be aware that the channel settings are per interface now, and needs to disallow (for now) real multi-channel operation, which is another important part of this patch. One of the immediate benefits is that you can now start hostapd to operate on a hardware that already has a connection on another virtual interface, as long as you specify the same channel. Note that two things are left unhandled (this is an improvement -- not a complete fix): * different HT/no-HT modes currently you could start an HT AP and then connect to a non-HT network on the same channel which would configure the hardware for no HT; that can be fixed fairly easily * CSA An AP we're connected to on a virtual interface might indicate switching channels, and in that case we would follow it, regardless of how many other interfaces are operating; this requires more effort to fix but is pretty rare after all Signed-off-by: Johannes Berg <johannes@sipsolutions.net> Signed-off-by: John W.

2010-04-16cfg80211: Avoid sending IWEVASSOCREQIE and IWEVASSOCRESPIE events with NULL ↵Nishant Sarmukadam
event body In a scenario, where a cfg80211 driver (station mode) does not send assoc request and assoc response IEs in cfg80211_connect_result after a successful association to an AP, cfg80211 sends IWEVASSOCREQIE and IWEVASSOCRESPIE to the user space application with NULL data. This can cause an issue at the event recipient. An example of this is when cfg80211 sends IWEVASSOCREQIE and IWEVASSOCRESPIE events with NULL event body to wpa_supplicant. The wpa_supplicant overwrites the assoc request and assoc response IEs for this station with NULL data. If the association is WPA/WPA2, the wpa_supplicant is not able to generate EAPOL handshake messages, since the IEs are NULL. With the patch, req_ie and resp_ie will be NULL by avoiding the assignment if the driver has not sent the IEs to cfg80211. The event sending code sends the events only if resp_ie and req_ie are not NULL. This will ensure that the events are not sent with NULL event body.

2010-04-07cfg80211: Add local-state-change-only auth/deauth/disassocJouni Malinen
cfg80211 is quite strict on allowing authentication and association commands only in certain states. In order to meet these requirements, user space applications may need to clear authentication or association state in some cases. Currently, this can be done with deauth/disassoc command, but that ends up sending out Deauthentication or Disassociation frame unnecessarily. Add a new nl80211 attribute to allow this sending of the frame be skipped, but with all other deauth/disassoc operations being completed. Similar state change is also needed for IEEE 802.11r FT protocol in the FT-over-DS case which does not use Authentication frame exchange in a transition to another BSS. For this to work with cfg80211, an authentication entry needs to be created for the target BSS without sending out an Authentication frame. The nl80211 authentication command can be used for this purpose, too, with the new attribute to indicate that the command is only for changing local state. This enables wpa_supplicant to complete FT-over-DS transition successfully. Signed-off-by: Jouni Malinen <j@w1.fi> Signed-off-by: John W. Linville <linville@tuxdriver.com>
