2008-12-12mac80211: integrate sta_notify_ps cmds into sta_notifyChristian Lamparter
This patch replaces the newly introduced sta_notify_ps function, which can be used to notify the driver about every power state transition for all associated stations, by integrating its functionality back into the original sta_notify callback.

2008-12-12p54usb: rewriting rx/tx routines to make use of usb_anchor's facilitiesChristian Lamparter
Alan Stern found several flaws in p54usb's implementation and annotated: "usb_kill_urb() and similar routines do not expect an URB's completion routine to deallocate it.  This is almost obvious -- if the URB is deallocated before the completion routine returns then there's no way for usb_kill_urb to detect when the URB actually is complete." This patch addresses all known limitations in the old implementation and fixes khub's "use-after-freed" hang, when SLUB debug's poisoning option is enabled.

2008-12-12ath9k: BH shouldn't be enabled when hardirqs are disabled.Senthil Balasubramanian
ath_tx_complete_buf uses a BH version of spinlock and so releasing the lock enables BH which is incorrect when called from sta_notify callback as MAC80211 disables hardirqs before the driver callback is called. As ath_tx_complete_buf is shared between user and softirq context using normal spinlock may not be appropriate. Though the proper fix would be to cleanup the context properly in the driver code, this would be an interim fix to avoid kernel warning.

2008-12-12mac80211: remove fragmentation offload functionalityJohannes Berg
There's no driver that actually does fragmentation on the device, and the callback is buggy (when it returns an error, mac80211's fragmentation status is changed so reading the frag threshold from userspace reads the new value despite the error). Let's just remove it, if we really find some hardware supporting it we can add it back later. Signed-off-by: Johannes Berg <johannes@sipsolutions.net> Signed-off-by: John W.

2008-12-12ath9k: Disable staggered Beacon frame schedulingJouni Malinen
It looks like there are some issues in the current ath9k version as far as staggered Beacon frame scheduling is concerned. This results in Beacon frame timestamp being off by 25 milliseconds or so which can cause issues with multicast power save buffering in AP mode. Some client stations fail to receive multicast frames when there is this large an offset between TBTT and actual Beacon transmission time. Since ath9k does not yet support multiple BSSes anyway, the staggered Beacon frame scheduling is just increasing the number of interrupts at this point. The easiest fix for the timestamp offset is to disable staggered Beacon frames for now. We need to redesign beacon.c anyway when adding multi-BSS support with mac80211 since the existing code depends on different mechanism for Beacon frame transmission.

2008-12-12iwl3945: Fix rate scale for B-mode connectionAbbas, Mohamed
This patch make sure we use only CCK rate for B only network. For 3945 driver, it sets REPLY_RATE_SCALE command every time we connect to a new network. In this command we set for every rate the number of try and next rate. The problem mac80211 reports same mode for both B and G mode as IEEE80211_BAND_2GHZ which will cause using invalid rate other than CCK in B only network. THis patch on association will examine sta valid rate on association, if no OFDM rate in valid available rates it considers it as B only mode so we can set REPLY_RATE_SCALE command with valid B only network and only choose CCK rate in rate scaling.

2008-12-12mac80211: remove WARN_ON() from ieee80211_hw_configReinette Chatre
ieee80211_hw_config can return an error when the hardware has rfkill enabled. A WARN_ON() is too harsh for this failure as it is a valid scenario. Only comment this warning as we would like to have it back when rfkill is integrated into mac80211. Also reintroduce propagation of error if ieee80211_hw_config fails in ieee80211_config_beacon.

2008-12-10netns: ip6mr: enable namespace support in ipv6 multicast forwarding codeBenjamin Thery
This last patch makes the appropriate changes to use and propagate the network namespace where needed in IPv6 multicast forwarding code. This consists mainly in replacing all the remaining init_net occurences with current netns pointer retrieved from sockets, net devices or mfc6_caches depending on the routines' contexts. Some routines receive a new 'struct net' parameter to propagate the current netns: * ip6mr_get_route * ip6mr_cache_report * ip6mr_cache_find * ip6mr_cache_unresolved * mif6_add/mif6_delete * ip6mr_mfc_add/ip6mr_mfc_delete * ip6mr_reg_vif All the IPv6 multicast forwarding variables moved to struct netns_ipv6 by the previous patches are now referenced in the correct namespace. Changelog: ========== * Take into account the net associated to mfc6_cache when matching entries in mfc_unres_queue list. * Call mroute_clean_tables() in ip6mr_net_exit() to free memory allocated per-namespace. * Call dev_net_set() in ip6mr_reg_vif() to initialize dev->nd_net correctly.

2008-12-10netns: ip6mr: declare counter cache_resolve_queue_len per-namespaceBenjamin Thery
Preliminary work to make IPv6 multicast forwarding netns-aware. Declare variable cache_resolve_queue_len per-namespace: moves it into struct netns_ipv6. This variable counts the number of unresolved cache entries queued in the list mfc_unres_queue. This list is kept global to all netns as the number of entries per namespace is limited to 10 (hardcoded in routine ip6mr_cache_unresolved). Entries belonging to different namespaces in mfc_unres_queue will be identified by matching the mfc_net member introduced previously in struct mfc6_cache. Keeping this list global to all netns, also allows us to keep a single timer (ipmr_expire_timer) to handle their expiration. In some places cache_resolve_queue_len value was tested for arming or deleting the timer. These tests were equivalent to testing mfc_unres_queue value instead and are replaced in this patch. At the moment, cache_resolve_queue_len is only referenced in init_net. Signed-off-by: Benjamin Thery <benjamin.thery@bull.net> Signed-off-by: David S. Miller <davem@davemloft.net>
