* rfkill: rework suspend and resume handlersHenrique de Moraes Holschuh2008-06-261-17/+18
| | | | | | | | | | | | | | | | The resume handler should reset the wireless transmitter rfkill state to exactly what it was when the system was suspended. Do it, and do it using the normal routines for state change while at it. The suspend handler should force-switch the transmitter to blocked state, ignoring caches. Do it. Also take an opportunity shot to rfkill_remove_switch() and also force the transmitter to blocked state there, bypassing caches.

* rfkill: add the WWAN radio typeHenrique de Moraes Holschuh2008-06-263-0/+9
| | | | | | | | | | | | | | | | Unfortunately, instead of adding a generic Wireless WAN type, a technology- specific type (WiMAX) was added. That's useless for other WWAN devices, such as EDGE, UMTS, X-RTT and other such radios. Add a WWAN rfkill type for generic wireless WAN devices. No keys are added as most devices really want to use KEY_WLAN for WWAN control (in a cycle of none, WLAN, WWAN, WLAN+WWAN) and need no specific keycode added.

* rfkill: add read-write rfkill switch supportHenrique de Moraes Holschuh2008-06-262-3/+55
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Currently, rfkill support for read/write rfkill switches is hacked through a round-trip over the input layer and rfkill-input to let a driver sync rfkill->state to hardware changes. This is buggy and sub-optimal. It causes real problems. It is best to think of the rfkill class as supporting only write-only switches at the moment. In order to implement the read/write functionality properly: Add a get_state() hook that is called by the class every time it needs to fetch the current state of the switch. Add a call to this hook every time the *current* state of the radio plays a role in a decision. Also add a force_state() method that can be used to forcefully syncronize the class' idea of the current state of the switch. This allows for a faster implementation of the read/write functionality, as a driver which get events on switch changes can avoid the need for a get_state() hook. If the get_state() hook is left as NULL, current behaviour is maintained, so this change is fully backwards compatible with the current rfkill drivers. For hardware that issues events when the rfkill state changes, leave get_state() NULL in the rfkill struct, set the initial state properly before registering with the rfkill class, and use the force_state() method in the driver to keep the rfkill interface up-to-date. get_state() can be called by the class from atomic context. It must not sleep. Signed-off-by: Henrique de Moraes Holschuh <hmh@hmh.eng.br> Acked-by: Ivo van Doorn <IvDoorn@gmail.com> Cc: Dmitry Torokhov <dtor@mail.ru> Signed-off-by: John W.

* rfkill: add parameter to disable radios by defaultHenrique de Moraes Holschuh2008-06-261-1/+10
| | | | | | | | | | | | | | | | | Currently, radios are always enabled when their rfkill interface is registered. This is not optimal, the safest state for a radio is to be offline unless the user turns it on. Add a module parameter that causes all radios to be disabled when their rfkill interface is registered. The module default is not changed so unless the parameter is used, radios will still be forced to their enabled state when they are registered. The new rfkill module parameter is called "default_state". Signed-off-by: Henrique de Moraes Holschuh <hmh@hmh.eng.br> Acked-by: Ivo van Doorn <IvDoorn@gmail.com> Signed-off-by: John W.

* rfkill: clarify meaning of rfkill statesHenrique de Moraes Holschuh2008-06-262-3/+10
| | | | | | | | | | | | | | | rfkill really should have been named rfswitch. As it is, one can get confused whether RFKILL_STATE_ON means the KILL switch is on (and therefore, the radio is being *blocked* from operating), or whether it means the RADIO rf output is on. Clearly state that RFKILL_STATE_ON means the radio is *unblocked* from operating (i.e. there is no rf killing going on).

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Three major portions to this change: 1) Add IW_EV_COMPAT_LCP_LEN, IW_EV_COMPAT_POINT_OFF, and IW_EV_COMPAT_POINT_LEN helper defines. 2) Delete iw_stream_check_add_*(), they are unused. 3) Add iw_request_info argument to iwe_stream_add_*(), and use it to size the event and pointer lengths correctly depending upon whether IW_REQUEST_FLAG_COMPAT is set or not. 4) The mechanical transformations to the drivers and wireless stack bits to get the iw_request_info passed down into the routines modified in #3.

The FW also implements a timeout algorithm and it honors all TCP flag, including the push flag as a trigger to halt aggregation.

Protection of Non-SCTP-Capable Hosts When an SCTP stack receives a packet containing multiple control or DATA chunks and the processing of the packet requires the sending of multiple chunks in response, the sender of the response chunk(s) MUST NOT send more than one packet. If bundling is supported, multiple response chunks that fit into a single packet MAY be bundled together into one single response packet. If bundling is not supported, then the sender MUST NOT send more than one response chunk and MUST discard all other responses. Note that this rule does NOT apply to a SACK chunk, since a SACK chunk is, in itself, a response to DATA and a SACK does not require a response of more DATA. We implement this by not servicing our outqueue until we reach the end of the packet. This enables maximum bundling.

| * | mac80211: detect driver tx bugsJohannes Berg2008-06-181-1/+8
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | When a driver rejects a frame in it's ->tx() callback, it must also stop queues, otherwise mac80211 can go into a loop here. Detect this situation and abort the loop after five retries, warning about the driver bug. Signed-off-by: Johannes Berg <johannes@sipsolutions.net> Signed-off-by: David S.
