| | | | | | | | | | | | | | | | | | | | Instead of modifying the HT SMPS capability field for stations, track the SMPS mode explicitly in a new field in the station struct and use it in the drivers that care about it.

| * mac80211: inform the driver about update of dtim_periodEmmanuel Grumbach2013-01-311-1/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Currently, when the driver requires the DTIM period, mac80211 will wait to hear a beacon before association. This behavior is suboptimal since some drivers may be able to deal with knowing the DTIM period after the association, if they get it at all. To address this, notify the drivers with bss_info_changed with the new BSS_CHANGED_DTIM_PERIOD flag when the DTIM becomes known. This might be when changing to associated, or later when the entire association was done with only probe response information. Rename the hardware flag for the current behaviour to IEEE80211_HW_NEED_DTIM_BEFORE_ASSOC to more accurately reflect its behaviour. IEEE80211_HW_NEED_DTIM_PERIOD is no longer accurate as all drivers get the DTIM period now, just not before association.

|/ | | | | | | | | | | | | | | | | | | | | | | | | | | When TX aggregation is stopped, there are a few different cases: - connection with the peer was dropped - session stop was requested locally - session stop was requested by the peer - connection was dropped while a session is stopping The behaviour in these cases should be different, if the connection is dropped then the driver should drop all frames, otherwise the frames may continue to be transmitted, aggregated in the case of a locally requested session stop or unaggregated in the case of the peer requesting session stop. Split these different cases so that the driver can act accordingly; however, treat local and remote stop the same way and ask the driver to not send frames as aggregated packets any more. In the case of connection drop, the stop callback the driver is otherwise supposed to call is no longer required. Signed-off-by: Johannes Berg <johannes.berg@intel.com>

This benefits processes that have very many mostly idle sockets, which is quite common. From Eric Dumazet. 10) Use up to 32K for page fragment allocations, with fallbacks to smaller sizes when higher order page allocations fail. Benefits are a) less segments for driver to process b) less calls to page allocator c) less waste of space. From Eric Dumazet. 11) Allow GRO to be used on GRE tunnels, from Eric Dumazet. 12) VXLAN device driver, one way to handle VLAN issues such as the limitation of 4096 VLAN IDs yet still have some level of isolation. From Stephen Hemminger. 13) As usual there is a large boatload of driver changes, with the scale perhaps tilted towards the wireless side this time around.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Some drivers (iwlegacy, iwlwifi and rt2x00) today use the bss_conf.last_tsf value. By itself though that value is completely worthless since it may be ancient. What really is needed is synchronisation between some device time and the TSF. To clarify this, rename bss_conf.last_tsf to sync_tsf and add sync_device_ts which is obtained from rx_status which gets a new field device_timestamp for this purpose. This is intentionally not using the mactime field since that is used for other things and in IBSS is expected to sync with the IBSS's TSF which isn't necessarily true for the device timestamp. Also, since we have the information and it's useful even before the connection has been established, give all the timing details to the driver before authenticating.

* | | iwlegacy: print how long queue was actually stuckPaul Bolle2012-06-281-3/+4
| |/ |/| | | | | | | | | | | | | | | | | | | | | | | | | | | Every now and then, after resuming from suspend, the iwlegacy driver prints iwl4965 0000:03:00.0: Queue 2 stuck for 2000 ms. iwl4965 0000:03:00.0: On demand firmware reload I have no idea what causes these errors. But the code currently uses wd_timeout in the first error. wd_timeout will generally be set at IL_DEF_WD_TIMEOUT (ie, 2000). Perhaps printing for how long the queue was actually stuck can clarify the cause of these errors. Signed-off-by: Paul Bolle <pebolle@tiscali.nl> Signed-off-by: John W.

This leads to a proliferation of the default_open() implementation across the entire tree. Now that the common implementation has been consolidated into libfs we can replace all the users of this function with simple_open(). This replacement was done with the following semantic patch: <smpl> @ open @ identifier open_f != simple_open; identifier i, f; @@ -int open_f(struct inode *i, struct file *f) -{ ( -if (i->i_private) -f->private_data = i->i_private; | -f->private_data = i->i_private; ) -return 0; -} @ has_open depends on open @ identifier fops; identifier open.open_f; @@ struct file_operations fops = { ... -.open = open_f, +.open = simple_open, ... }; </smpl> [akpm@linux-foundation.org: checkpatch fixes] Signed-off-by: Stephen Boyd <sboyd@codeaurora.org> Cc: Greg Kroah-Hartman <gregkh@linuxfoundation.org> Cc: Al Viro <viro@zeniv.linux.org.uk> Cc: Julia Lawall <Julia.Lawall@lip6.fr> Acked-by: Ingo Molnar <mingo@elte.hu> Signed-off-by: Andrew Morton <akpm@linux-foundation.org> Signed-off-by: Linus Torvalds <torvalds@linux-foundation.org>
* | | mac80211: remove antenna_sel_tx TX info fieldJohannes Berg2012-04-102-3/+3
|/ / | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This field is never set to anything non-zero in mac80211, so we should be able to remove it. Unfortunately though, the iwlwifi and iwlegacy drivers use it for their internal TX status processing (which shouldn't be using the rate control API to start with), so add a new field "status.antenna" for them, at least for now. In the future, I plan to use the new field to hold the hardware queue, while the SKB's queue mapping holds the AC. Signed-off-by: Johannes Berg <johannes.berg@intel.com> Signed-off-by: John W.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Current commit 0775f9f90cdaf40fbf69b3192b3dddb2b3436f45 "mac80211: remove spurious BSSID change flag" exposed bug on iwlegacy, that we do not set BSSID address correctly and then device was not able to receive frames after successful associate. On the way fix scan canceling comment. Apparently ->post_associate() do cancel scan itself, but scan cancel on BSS_CHANGED_BSSID is needed. I'm not sure why, but when I removed it, I had frequent auth failures: wlan4: send auth to 54:e6:fc:98:63:fe (try 1/3) wlan4: send auth to 54:e6:fc:98:63:fe (try 2/3) wlan4: send auth to 54:e6:fc:98:63:fe (try 3/3) wlan4: authentication with 54:e6:fc:98:63:fe timed out Signed-off-by: Stanislaw Gruszka <sgruszka@redhat.com> Signed-off-by: John W.
