When, for instance, a new IBSS peer is found, userspace wants to be notified. Add events for all new stations that mac80211 learns about. Signed-off-by:

This changes mac80211 to allow being off-channel for any type of work, not just the 'remain-on-channel' work. This also helps fast transition to a BSS on a different channel. Signed-off-by:

This implements the new remain-on-channel cfg80211 command in mac80211, extending the work interface. Also change the work purge code to be able to clean up events properly (pretending they timed out.) Signed-off-by:

Add new commands for requesting the driver to remain awake on a specified channel for the specified amount of time (and another command to cancel such an operation). This can be used to implement userspace-controlled off-channel operations, like Public Action frame exchange on another channel than the operation channel. The off-channel operation should behave similarly to scan, i.e. the local station (if associated) moves into power save mode to request the AP to buffer frames for it and then moves to the other channel to allow the off-channel operation to be completed. The duration parameter can be used to request enough time to receive a response from the target station. Signed-off-by:

The off-channel operations for going into power save mode (station mode) or stop beaconing (AP/IBSS) are not limited to scanning. Move these into a separate file and allow them to be used for other purposes, too. Signed-off-by:

cfg80211 offers private data for each BSS struct, which mac80211 uses. However, mac80211 uses internal and external (cfg80211) BSS pointers interchangeably and has a hack to put the cfg80211 bss struct into the private struct. Remove this hack, properly converting between the pointers wherever necessary. Signed-off-by:

Currently, we insert all user-specified IEs before the HT IE for association, and after the HT IE for probe requests. For association, that's correct only if the user-specified IEs are RSN only, incorrect in all other cases including WPA. Change this to split apart the user-specified IEs in two places for association: before the HT IE (e.g. RSN), after the HT IE (generally empty right now I think?) and after WMM (all other vendor-specific IEs). For probes, split the IEs in different places to be correct according to the spec. Signed-off-by:

Refactor the code to reserve an skb of the right size (instead of hoping 200 bytes are enough forever), and also put HT IE generation into an own function. Additionally, put the HT IE before the vendor-specific WMM IE. This still leaves things not quite ordered correctly, due to user-specified IEs, add a note about that for now. Signed-off-by:

The station we're authenticating/associating with may not always be an AP in the sense that word is mostly understood, so print only the MAC address of the peer instead. Signed-off-by:

In order to use auth/assoc for different purposes other than MLME, it needs to be split up. For other purposes, a generic work handling (potentially on another channel) will be useful. To achieve that, this patch moves much of the MLME work handling out of mlme into a new work API. The API can currently handle probing a specific AP, authentication and association. The MLME previously handled probe/authentication as one step and will continue to do so, but they are separate in the new work handling. Work items are RCU-managed to be able to check for existence of an item for a specific frame in the RX path, but they can be re-used which the MLME right now will do for its combined probe/auth step.

As a first step of generalising management work, this renames a few things and puts more information directly into the struct so that auth/assoc need not access the BSS pointer as often -- in fact it can be removed from auth completely. Also since the previous patch made sure a new work item is used for association, we can make the different data a union. Signed-off-by:

mac80211 currently hangs on to the auth state by keeping it on the work list. That can lead to confusing behaviour like rejecting scans while authenticated to any AP (but not yet associated.) It also means that it needs to keep track of the work struct while associated for when it gets disassociated (or disassociates.) Change this to free the work struct after the authentication completed successfully and allocate a new one for associating, thereby letting cfg80211 manage the auth state. Another change necessary for this is to tell cfg80211 about all unicast deauth frames sent to mac80211 since now it can no longer check the auth state, but that check was racy anyway. Signed-off-by:

We've long lacked a good confirmation that frames have really gone out, e.g. before going off-channel for a scan. Add a flush() operation that drivers can implement to provide that confirmation, and use it in a few places: * before scanning sends the nullfunc frames * after scanning sends the nullfunc frames, if any * when going idle, to send any pending frames Signed-off-by:

Instead of always using netif_running(sdata->dev) use ieee80211_sdata_running(sdata) now which is just an inline containing netif_running() for now. Signed-off-by:

It is checked in add_interface, but there it is easily replaced with a check of priv->vif. If that information should become necessary, it is available in vif->type anyway. It is also checked in led_turn_on and led_turn_off, where I made the substitutions as described above. Of course, these checks seem to have been incorrect since the driver was using NL80211_IFTYPE_MONITOR to indicate no interface rather than NL80211_IFTYPE_UNSPECIFIED. Anyway, I think these checks may be extraneous...? Signed-off-by: -

Let each of them take a struct rt2x00_dev pointer as argument instead of a mixture of struct rt2x00_chip and struct rt2x00_dev pointers. Preparation for further clean ups in the rt2x00 chip handling, especially for rt2800 devices. Signed-off-by:

There is no need for Kconfig symbols RT2800PCI_PCI and RT2800PCI_SOC to be tristates, as they are only used to check whether RT2800 PCI or SOC support is to be compiled in. Signed-off-by:

rt2800lib currently checks whether RT2800USB is enabled in the configuration. Strictly speaking this is not necessary, it only needs to know whether the generic rt2x00usb library functions are available. Therefore check for RT2X00_LIB_USB instead. Signed-off-by:

Because the interface is started and the vif are created and destroyed separately, there is a slim possibility beacon-loss indications occur while there is no vif - causing a kernel-oops unless checked. Add checking for the vif. Signed-off-by:

Previously, only basic rates were used for data transmission - resulting in reduced transfer rates. This patch takes enables the firmware to take advantage of the full set of data rates supported by the AP. Signed-off-by:
-
Juuso Oikarinen authored
Previously a "firmware chooses" value was used for the rates of all control message templates set to the firmware. This resulted in a too high rate to be chosen to transmit those messages. Change this by configuring a fixed low rate for the templates. Signed-off-by:

This patch adds rudimentary a-hoc support for the driver. It will allow setting up ad-hoc, and for other devices to scan and join. The beacon and probe response template setting is slightly dirty, and need to be properly implemented with support from mac80211. Also, the SSID is not configured to the firmware - the FW will not be able to respond to probe requests autonomously. Signed-off-by:

This patch adds a short delay before powering on the wl1271. Normally, it is not needed, but if the wl1271 has been powered off shortly before, for reliable firmware-booting this small stabilization delay is required. Signed-off-by:

In the data path configuration, one of the parameters is the channel. We have been setting it to wl->channel, which is not correct in this case. This channel has nothing to do with the channel we're currently tuned to, since it is only used for calibration during this phase. Hardcoded the channel to 1, according to the reference driver.

We were uploading the whole NVS file, but that is wrong, because the same file also contains the initialization values. For the latest firmwares, we should upload only the initial 468 bytes from the file. Signed-off-by:

Some debugging tools require the chip to be powered on before they can work. With these tools, we shouldn't upload the firmware nor boot the firmware ourselves, so this debufs file is provided. It always contains the gpio power setting (0 = off, 1 = on). To change the power setting, just write 0 or 1 to the file. Signed-off-by:
