cfg80211_chan_def and ieee80211_channel recently gained a frequency offset component. Handle this where it makes sense (potentially required by S1G channels). For IBSS, TDLS, CSA, and ROC we return -EOPNOTSUPP if a channel with frequency offset is passed, since they may or may not work. Once someone tests and verifies these commands work on thos types of channels, we can remove that error. join_ocb and join_mesh look harmless because they use a simple ieee80211_vif_use_channel(), which is using an already verified channel, so we let those through.

Some bands (S1G) define channels centered on a non-integer MHz. Give ieee80211_channel and cfg80211_chan_def a freq_offset component where the final frequency can be expressed as: MHZ_TO_KHZ(chan->center_freq) + chan->freq_offset; Also provide some helper functions to do the frequency conversion and test for equality. Retain the existing interface to frequency and channel conversion helpers, and expose new ones which handle frequencies in units of KHz. Some internal functions (net/wireless/chan.c) pass around a frequency value. Convert these to units of KHz. mesh, ibss, wext, etc. are currently ignored. Signed-off-by:

The MLME logic had a workaround that allowed to continue an association with an AP even if the AP did not provide any basic rates in its supported rates in the association response, assuming that the first (non basic) legacy rate could be used as a basic rate. However, this did not consider the case where the AP (which is obviously buggy) did not provide any legacy rate. Fix this by failing the association, as this can result in an unexpected failure in the low level driver and FW, e.g., in rate scale logic etc. Signed-off-by:

Driver tells mac80211 to sends ADDBA with SSN (starting sequence number) from the head of the queue, while the transmission of all the frames in the queue may take a while, which causes the peer to time out. In order to fix this scenario, add an option to defer ADDBA transmit until queue is drained. Signed-off-by:

Somehow we missed this for a long time, but similar to the extended NSS support in VHT capabilities, we need to have this in Operating Mode notification. Implement it by * parsing the 160/80+80 bit there and setting the bandwidth appropriately * having callers of ieee80211_get_vht_max_nss() pass in the current max NSS value as received in the operating mode notification in order to modify it appropriately depending on the extended NSS bits. This updates all drivers that use it, i.e. only iwlwifi/mvm. Signed-off-by:

Almost all drivers below cfg80211 get the API wrong (except for cfg80211) and are unable to cope with multiple registrations for the same frame type, which is valid due to the match filter. This seems to indicate the API is wrong, and we should maintain the full information in cfg80211 instead of the drivers. Change the API to no longer inform the driver about individual registrations and unregistrations, but rather every time about the entire state of the entire wiphy and single wdev, whenever it may have changed. This also simplifies the code in cfg80211 as it no longer has to track exactly what was unregistered and can free things immediately. Signed-off-by:

Extend cfg80211_rx_unprot_mlme_mgmt() to cover indication of unprotected Beacon frames in addition to the previously used Deauthentication and Disassociation frames. The Beacon frame case is quite similar, but has couple of exceptions: this is used both with fully unprotected and also incorrectly protected frames and there is a rate limit on the events to avoid unnecessary flooding netlink events in case something goes wrong.

Maintain the connection AID only in sdata->vif.bss_conf.aid, not also in sdata->u.mgd.aid. Keep setting that where we set ifmgd->aid before, which has the side effect of exposing the AID to the driver before the station entry (AP) is marked associated, in case it needs it then. Requested-by:

Currently, wmediumd requires each used MAC address to be configured as a station in the virtual air, but that doesn't make sense as any station could have multiple MAC addresses, and even have randomized ones in scanning, etc. Add some code here to tell wmediumd of used MAC addresses, binding them to the hardware address. Combined with a wmediumd patch that makes it track the addresses this allows configuring just the radio address (42:00:00:00:nn:00 unless the radio was manually created) in wmediumd as a station, and all addresses that the station uses are added/removed dynamically. Tested with random scan, which without this and the corresponding wmediumd change doesn't get anything through as the sender doesn't exist as far as wmediumd is concerned (it's random).

In kernel datapath of Open vSwitch, there are only 1024 buckets of meter in one datapath. If installing more than 1024 (e.g. 8192) meters, it may lead to the performance drop. But in some case, for example, Open vSwitch used as edge gateway, there should be 20K at least, where meters used for IP address bandwidth limitation. [Open vSwitch userspace datapath has this issue too.] For more scalable meter, this patch use meter array instead of hash tables, and expand/shrink the array when necessary. So we can install more meters than before in the datapath. Introducing the struct *dp_meter_instance, it's easy to expand meter though changing the *ti point in the struct *dp_meter_table.

In this series, I've tried to restructure and split changes, and also add few additional optimizations comparing to initial RFC submission [1]. The HW_TS_PUSH events intended to serve for different timesync purposes on of which is to add PPS generation function, which can be implemented as below: +-----------------+ | Control | | application | +------->+ +----------+ | | | | | | | | | +-----------------+ | | | | | | PTP_EXTTS_REQUEST | | | | | +----------------------------------------------------------------+ | | Kernel +-------+----------+ +-------v--------+ | \dev\ptpX | | /sys/class/pwm/| | | | | +-------^----------+ +-------+--------+ | | | | | +-------v-------------------+ +-------+----------+ | | | CPTS driver | |pwm/pwm-omap-dmtimer.c | | | +---------------------------+ +-------^----------+ |clocksource/timer_ti_dm.c | | +-------+-------------------+ |HWx_TS_PUSH evt | +----------------------------------------------------------------+ | | HW +-------+----------+ +-------v--------+ | CPTS | | DMTimer | | | | | | HWx_TS_PUSH X<-----------------+ | | + | | +------------------+ +-------+--------+ | X timer4 As per my knowledge there is at least one public implemented above PPS generation schema from Tusori Tibor [2] based on initial HW_TS_PUSH enable submission[1].
