* mac80211: allow GO to scan like APJohannes Berg2011-02-031-2/+5

* mac80211: add HW flag for disabling auto link-PS in AP modeArik Nemtsov2011-02-033-3/+31
| | | | | | | | | | | | | When operating in AP mode the wl1271 hardware filters out null-data packets as well as management packets. This makes it impossible for mac80211 to monitor the PS mode by using the PM bit of incoming frames. Implement a HW flag to indicate that mac80211 should ignore the PM bit. In addition, expose ieee80211_sta_ps_transition() to make low-level drivers capable of controlling PS-mode. Signed-off-by: Arik Nemtsov <arik@wizery.com> Signed-off-by: John W.

* mac80211: do not calc frame duration when using HW rate-controlArik Nemtsov2011-02-031-1/+2
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | When rate-control is performed in HW, we cannot calculate frame duration as we do not have the skb transmission rate in SW. ieee80211_tx_h_calculate_duration() should only be called when ieee80211_tx_h_rate_ctrl() has been called before to initialize data in skb->cb. This doesn't happen for drivers with HW rate-control. Fixes the following warning when operating in AP-mode in a driver with HW rate-control.

* cfg80211: Fix power save state after interface type changeJuuso Oikarinen2011-02-031-7/+13
| | | | | | | | | | | | | | | | | Currently cfg80211 only configures the PSM state to the driver upon creation of a new virtual interface, but not after interface type change. The mac80211 on the other hand reinitializes its sdata structure every time the interface type is changed, losing the PSM configuration. Hence, if the interface type is changed to, say, ad-hoc and then back to managed, "iw wlan0 get power_save" will claim that PSM is enabled, when in fact on mac80211 level it is not. Fix this in cfg80211 by configuring the PSM state to the driver each time the interface is brought up instead of just when the interface is created.

When an interface is changed using the change_interface op, the mode specific sdata part is in an undefined state and trying to get a beacon at this point can produce weird crashes.

| * Bluetooth: Fix race condition with conn->sec_levelJohan Hedberg2011-01-192-6/+11
| | | | | | | | | | | | | | | | | | | | | | | | The conn->sec_level value is supposed to represent the current level of security that the connection has. However, by assigning to it before requesting authentication it will have the wrong value during the authentication procedure. To fix this a pending_sec_level variable is added which is used to track the desired security level while making sure that sec_level always represents the current level of security.

Additionally the l2cap_check_security code was completely missing the handling of SOCK_RAW type sockets.

That commit is wrong for two reasons: - The conn->sec_level shouldn't be updated without performing authentication first (as it's supposed to represent the level of security that the existing connection has) - A higher auth_type value doesn't mean "more secure" like the commit seems to assume. E.g. dedicated bonding with MITM protection is 0x03 whereas general bonding without MITM protection is 0x04. hci_conn_auth already takes care of updating conn->auth_type so hci_connect doesn't need to do it.

Because there are now overlapping channel numbers in the 2GHz and 5GHz band we can't map from channel to frequency without knowing the band. This is no problem as in most contexts we know the band. In places where we don't know the band (and WEXT compatibility) we assume the 2GHz band for channels below 14. This patch does not implement all channel to frequency mappings defined in 802.11, it's just an extension for 802.11j 20MHz channels. 5MHz and 10MHz channels as well as 802.11y channels have been omitted.

I'm not sure why this is happening yet, but I think it's a good idea to drop all frames (except 802.1x/EAP frames) that do not match the configured addressing mode, including 4-address frames sent to a 3-address station.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Currently, mac80211 always advertises that it may send up to 64 subframes in an aggregate.

However, drivers might have that information, so allow them to set a variable giving it, which will then be used.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The aggregation code currently doesn't implement the buffer size negotiation. It will always request a max buffer size (which is fine, if a little pointless, as the mac80211 code doesn't know and might just use 0 instead), but if the peer requests a smaller size it isn't possible to honour this request. In order to fix this, look at the buffer size in the addBA response frame, keep track of it and pass it to the driver in the ampdu_action callback when called with the IEEE80211_AMPDU_TX_OPERATIONAL action. That way the driver can limit the number of subframes in aggregates appropriately. Note that this doesn't fix any drivers apart from the addition of the new argument -- they all need to be updated separately to use this variable!

Only remaining users are ixgbe, sch_teql, gianfar & macvlan : 1) ixgbe can be converted to use existing tx_ring counters. 2) macvlan incremented txq->tx_dropped, it can use the dev->stats.tx_dropped counter. 3) sch_teql : almost revert ab35cd4b8f42 (Use net_device internal stats) Now we have ndo_get_stats64(), use it, even for "unsigned long" fields (No need to bring back a struct net_device_stats) 4) gianfar adds a stats structure per tx queue to hold tx_bytes/tx_packets This removes a lockdep warning (and possible lockup) in rndis gadget, calling dev_get_stats() from hard IRQ context.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This patch fixes a loop in ctnetlink_get_conntrack() that can be triggered if you use the same socket to receive events and to perform a GET operation. Under heavy load, netlink_unicast() may return -EAGAIN, this error code is reserved in nfnetlink for the module load-on-demand. Instead, we return -ENOBUFS which is the appropriate error code that has to be propagated to user-space.

A connection associated with the channel(s) of one session may be simultaneously associated with the channel(s) of other sessions including sessions associated with other client IDs. However, multiple backchannels share a connection, they must all share the same xid stream (hence the same rpc_xprt); the only way we have to match replies with calls at the rpc layer is using the xid. So, keep the rpc_xprt around as long as the connection lasts, in case we're asked to use the connection as a backchannel again. Requests to create new backchannel clients over a given server connection should results in creating new clients that reuse the existing rpc_xprt. But to start, just reject attempts to associate multiple rpc_xprt's with the same underlying bc_xprt. Signed-off-by: J. Bruce Fields <bfields@redhat.com>
