* mac80211: respond to beacon loss report only onceJohannes Berg2009-05-13
| | | | | | | | | | The driver might keep reporting beacon loss until we disassociate -- catch that and don't respond to any subsequent events until the probe is either successful or we disassociate.

* wext: remove seq_start/stop sparse annotationsJohannes Berg2009-05-13
| | | | | | | | | | | | | Even though they are true, they cause sparse to complain because it doesn't see the __acquires(dev_base_lock) on dev_seq_start() because it is only added to the function in net/core/dev.c, not the header file. To keep track of the nesting correctly we should probably annotate those functions publically, but for now let's just remove the annotation I added to wext.

* nl80211: Add RSC configuration for new keysJouni Malinen2009-05-13
| | | | | | | | | | | | | When setting a key with NL80211_CMD_NEW_KEY, we should allow the key sequence number (RSC) to be set in order to allow replay protection to work correctly for group keys. This patch documents this use for nl80211 and adds the couple of missing pieces in nl80211/cfg80211 and mac80211 to support this. In addition, WEXT SIOCSIWENCODEEXT compat processing in cfg80211 is extended to handle the RSC (this was already specified in WEXT, but just not implemented in cfg80211/mac80211).

* nl80211: Add IEEE 802.1X PAE control for station modeJouni Malinen2009-05-13
| | | | | | | | | | | | | | | Add a new NL80211_ATTR_CONTROL_PORT flag for NL80211_CMD_ASSOCIATE to allow user space to indicate that it will control the IEEE 802.1X port in station mode. Previously, mac80211 was always marking the port authorized in station mode. This was enough when drop_unencrypted flag was set. However, drop_unencrypted can currently be controlled only with WEXT and the current nl80211 design does not allow fully secure configuration. Fix this by providing a mechanism for user space to control the IEEE 802.1X port in station mode (i.e., do the same that we are already doing in AP mode).

* nl80211: improve station flags handlingJohannes Berg2009-05-13
| | | | | | | | | | | | | | | It is currently not possible to modify station flags, but that capability would be very useful. This patch introduces a new nl80211 attribute that contains a set/mask for station flags, and updates the internal API (and mac80211) to mirror that. The new attribute is parsed before falling back to the old so that userspace can specify both (if it can) to work on all kernels.

The previous version added the flag due to the loop used in parse_station_flags, but the proper behavior would be to allow nla_parse_nested() to go through the policy for all flags.

* cfg80211: implement wext key handlingJohannes Berg2009-05-13
| | | | | | | | | | | | | | | | | | | Move key handling wireless extension ioctls from mac80211 to cfg80211 so that all drivers that implement the cfg80211 operations get wext compatibility. Note that this drops the SIOCGIWENCODE ioctl support for getting IW_ENCODE_RESTRICTED/IW_ENCODE_OPEN. This means that iwconfig will no longer report "Security mode:open" or "Security mode:restricted" for mac80211. However, what we displayed there (the authentication algo used) was actually wrong -- linux/wireless.h states that this setting is meant to differentiate between "Refuse non-encoded packets" and "Accept non-encoded packets".

* wext: fix get_wireless_stats lockingJohannes Berg2009-05-11
| | | | | | | | | | | | | | | | | | | | | Currently, get_wireless_stats is racy by _design_. This is because it returns a buffer, which needs to be statically allocated since it cannot be freed if it was allocated dynamically. Also, SIOCGIWSTATS and /proc/net/wireless use no common lock, and /proc/net/wireless accesses are not synchronised against each other. This is a design flaw in get_wireless_stats since the beginning. This patch fixes it by wrapping /proc/net/wireless accesses with the RTNL so they are protected against each other and SIOCGIWSTATS. The more correct method of fixing this would be to pass in the buffer instead of returning it and have the caller take care of synchronisation of the buffer, but even then most drivers probably assume that their callback is protected by the RTNL like all other wext callbacks.

Public and Vendor-specific categories are marked as not Robust in IEEE 802.11w; HT will be marked not Robust in IEEE 802.11n. A new Vendor-specific Protected category is allocated for Robust vendor-specific Action frames.

* iwlwifi: clean up PS codeJohannes Berg2009-05-11
| | | | | | | | | | | | | | | | | | | | | | This removes all the dead code that tries to adjust the power saving level based on the system AC state (inacceptable policy in the kernel) or based on overtemp conditions (unused). Also, pass _all_ policy wrt. enabling PS to mac80211, since we do not use the power_disabled internally I now use that to mirror the mac80211 CONF_PS setting. When mac80211 turns off CONF_PS we follow suit. This means that the user power level (which can currently only be set from sysfs) is not touched for mac80211 powersave changes. This means no "association status" checks are necessary since mac80211 will not allow power save to be enabled when not associated.

* iwlwifi: fix PS disable status raceJohannes Berg2009-05-11
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | iwlwifi internally needs to keep track of whether PS is enabled in the firmware or not. To do this, it keeps a bit in the status flags, called STATUS_POWER_PMI. The code to set this bit looks as follows: static int iwl_set_power(struct iwl_priv *priv, void *cmd) { return iwl_send_cmd_pdu_async(priv, POWER_TABLE_CMD, sizeof(struct iwl_powertable_cmd), cmd, NULL); } int iwl_power_update_mode(...) { [...] if (final_mode != IWL_POWER_MODE_CAM) set_bit(STATUS_POWER_PMI, &priv->status); iwl_update_power_cmd(priv, &cmd, final_mode); cmd.keep_alive_beacons = 0; if (final_mode == IWL_POWER_INDEX_5) cmd.flags |= IWL_POWER_FAST_PD; ret = iwl_set_power(priv, &cmd); if (final_mode == IWL_POWER_MODE_CAM) clear_bit(STATUS_POWER_PMI, &priv->status); else set_bit(STATUS_POWER_PMI, &priv->status); if (priv->cfg->ops->lib->update_chain_flags && update_chains) priv->cfg->ops->lib->update_chain_flags(priv); [...] } Now, this bit really needs to track what the _firmware_ thinks, not what the driver thinks. Therefore, there is a race condition here -- the driver sets the bit before it knows that the async command sent to the card in the iwl_set_power function has been processed. As a result, the call to update_chain_flags() may think that the card has been woken up (PMI bit cleared) while in reality it hasn't processed the async POWER_TABLE_CMD yet. This leads to bugs -- any commands the update_chain_flags function sends can get stuck and subsequent commands also fail. The fix is almost trivial: since there's no reason to send an async command here (in fact, there almost never should be since many mac80211 callbacks can sleep) just make the function wait for the card to process the command and then return and clear the PMI bit.

* mac80211: improve scan timingJohannes Berg2009-05-11
| | | | | | | | | | | | | | | | | | | | | The call to ieee80211_hw_config() is supposed to apply changes synchronously, so once it returns the parameters are applied to the hardware. Thus, there really is no need to delay the probing by the channel switch time again since the channel switch has already happened once we get to this code. Additionally, there is no need to wait for a NAV update (probe delay) when the channel is passively scanned. Remove that extra time too. This cuts scanning time from over 7 seconds to under 4 on ar9170, which is due to the number of channels scanned and ar9170's switch time being advertised as 135ms (my test now indicates it is about 77ms with the current driver, but the difference might also be due to using a different machine with different USB controllers).

* mac80211: MFP - Drop unprotected Action frames prior key setupJouni Malinen2009-05-11
| | | | | | | | | | | | | | | | | When management frame protection (IEEE 802.11w) is used, unprotected Robust Action frames are not allowed prior to key configuration. However, unprotected Deauthentication and Disassociation frames are allowed at that point, but not after key configuration. Make ieee80211_drop_unencrypted() handle the special cases for MFP by separating the basic Data frame case from Management frame processing and handle the Management frames only if MFP has been negotiated. In addition, do not use sdata->drop_unencrypted for Management frames since the decision on whether to accept the frame depends on the key being configured.

* mac80211: Drop unencrypted frames based on key setupJouni Malinen2009-05-11
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | When using nl80211, we do not have a mechanism to set sdata->drop_unencrypted. Currently, this breaks code that is supposed to drop unencrypted frames when protection is expected since ieee80211_rx_h_decrypt() is optimized to not set rx->key when the frame is not protected. This patch modifies ieee80211_rx_h_decrypt() to set rx->key for all frames and only skip decryption if the frame is not protected. This allows ieee80211_drop_unencrypted() to correctly drop frames even if drop_unencrypted is not set. The changes here are not enough to handle all cases, though. Additional patches will be needed to implement proper IEEE 802.1X PAE for station mode (currently, this is only used for AP mode) and some additional rules are needed for MFP to drop unprotected Robust Action frames prior to having PTK and IGTK configured. In theory, the unprotected frames could and should be dropped in ieee80211_rx_h_decrypt(). However, due to the special case with EAPOL frames that have to be allowed to be received unprotected even when keys are set, it is simpler to only set rx->key and allow the ieee80211_frame_allowed() function to handle the actual dropping of data frames after 802.11->802.3 header conversion. In addition, unprotected robust management frames are dropped before they are processed. Signed-off-by: Jouni Malinen <jouni.malinen@atheros.com> Signed-off-by: John W.

| | | | | | | | | | | | | | | | | The function to parse a struct iw_freq has a stupid bug, it returns NULL when the channel cannot be found at all, but NULL is supposed to mean "auto".

This fixes an issue where you could say (in IBSS mode) iwconfig wlan0 channel 21 and it would use channel 1 instead because that's the first available channel with IBSS allowed (which is what the "auto" setting uses).

* mac80211: fix scan channel raceJohannes Berg2009-05-11
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | When a software scan starts, it first sets sw_scanning, but leaves the scan_channel "unset" (it currently actually gets initialised to a default). Now, when something else tries to (re)configure the hardware in the window between these two events (after sw_scanning = true, but before scan_channel is set), the current code switches to the (unset!) scan_channel. This causes trouble, especially when switching bands and sending frames on the wrong channel. To work around this, leave scan_channel initialised to NULL and use it to determine whether or not a switch to a different channel should occur (and also use the same condition to check whether to adjust power for scan or not). Additionally, avoid reconfiguring the hardware completely when recalculating idle resulted in no changes, this was the problem that originally led us to discover the race condition in the first place, which was helpfully bisected by Pavel. This part of the patch should not be necessary with the other fixes, but not calling the ieee80211_hw_config function when we know it to be unnecessary is certainly a correct thing to do. Unfortunately, this patch cannot and does not fix the race condition completely, but due to the way the scan code is structured it makes the particular problem Pavel discovered (race while changing channel at the same time as transmitting frames) go away. To fix it completely, more work especially with locking configuration is needed.

* Network Drop Monitor: Fix skb_kill_datagramJohn Dykstra2009-05-08
| | | | | | | | | | | | | Commit ead2ceb0ec9f85cff19c43b5cdb2f8a054484431 ("Network Drop Monitor: Adding kfree_skb_clean for non-drops and modifying end-of-line points for skbs") established new conventions for identifying dropped packets. Align skb_kill_datagram() with these conventions so that packets that get dropped just before the copy to userspace are properly tracked.
