Add initial 802.11ac (VHT) support to net80211. Add VHT capability and operation IE definitions to ieee80211.h. Introduce channel flags to identify 80MHz and 160MHz capable channels. Parse VHT IEs in beacons, announce the driver's VHT capabilities in probe requests and assoc requests, and hop into 11ac mode after association to the AP if possible. Enable VHT by default if the driver announces support for it. ok claudio@

Fix and re-enable active scans on iwm(4) and iwx(4). Ensure that we supply the access point's DTIM period to firmware after an active scan, as soon as the next beacon arrives. This prevents the problems which prompted us to keep active scans disabled in our drivers. Problem debugged and patch by zxystd from the OpenIntelWireless project. I made some tweaks regarding TIM parsing, which were reviewed by zxystd. Johannes Berg from Intel has confirmed to me via IRC that firmware will misbehave if running with a zero DTIM period. Tested: 8265: jca, stsp 9260: kettenis (possible fallout observed here; will keep an eye on it) 9650: stsp ax200: zxystd, kevlo, stsp ax201: stsp ok kevlo@ kettenis@

Defer rtm_80211info() call from ieee80211_set_link_state() to a task context. Sending routing messages requires a socket lock which may sleep. ieee80211_set_link_state() is called from interrupts and timeouts where sleeping is not allowed. mvs@ pointed out that if_link_state_change() is already using a task for this reason.

Introduce an optional driver-specific bgscan_done() handler which allows the driver to take control of the roaming teardown sequence. This handler allows drivers to ensure that race conditions between firmware state and net80211 state are avoided, and will be used by the iwm(4) and iwx(4) drivers soon. Split the existing roaming teardown sequence into two steps, one step for tearing down Tx block ack sessions which sends a DELBA frame, and a second step for flushing Tx rings followed by sending a DEAUTH frame. We used to queue both frames, expecting to switch APs once both were sent. Now we effectively expect everything to be sent before we queue a final DEAUTH frame, and wait for just this frame to be sent before switching. This already made issues on iwm/iwx less frequent but by itself this was not enough to close all races for those drivers. It should however help when adding background scan support to a non-firmware device driver. Tested, with driver patches: iwm 8265: Aaron Poffenberger, stsp iwm 9260: florian iwm 9560: sthen iwx ax200: jmc, stsp

Add support for 40MHz channels to net80211 RA. For the moment we use either the 40MHz rate set or the 20 MHz one, depending on whether our peer supports 40MHz channels. If this turns out to be suboptimal we could probe the 40MHz and 20MHz rate sets separately to detect which one works better. The same applies to use of the short guard interval (SGI), which is either always on or off at the moment. Again, probing for this could be added later if needed.

Raise net80211's "beacon miss" threshold to avoid frequent re-connects to APs that are relatively far away and suffer some packet loss. The former threshold was 7 beacons (about 700 ms). This raises the threshold to 30 beacons (about 3 seconds). Should still be good enough for detecting APs that have disappeared, and makes wifi networks provided by the University of Bucharest more reliable in the p2k19 hackroom. While here, make 'ifconfig iwm0/iwn0 debug' print an obvious message when we believe that the AP has disappeared. Problem reported and fix tested by landry@ / pirofti@ ok mpi@ sthen@

Add support for 802.11n Tx aggregation to net80211 and the iwn(4) driver. In particular, add Tx block ack session management to net80211, with enough funcionality to support Tx aggregation on devices which perform A-MPDU subframe scheduling in firmware. Make use of the iwn(4) firmware Tx scheduler to build A-MPDUs. net80211's QoS support code is now enabled and used by Tx aggregation. A-MSDU frames inside A-MPDUs have been tested and work in principle. For now, this feature is disabled because unfair TCP connection sharing was observed during testing, where bursts of TCP Ack frames for a single tcpbench(1) connection arriving in A-MSDUs made other TCP connections stall. Switch off support for A-MSDUs inside A-MPDUs on the Rx side as well. Tested on iwn chipsets 1000, 4965, 5100, 5300, 2200, 6200, 6205, 6300 (committed version of tested diff has all debug printfs removed) tests/ok benno kmos mlarkin kevlo

Make 'ifconfig nwid' override 'ifconfig join'. There was no way to override a decision made by join's network selection algorithm (apart from disabling the feature by clearing the join list). Automatic selection is based on heuristics which cannot always guess correctly so we need to provide an override. One specific problem was that if 'nwid foo' and 'nwid bar' were both visible in the scan and only 'nwid foo' was a member of the join list, then there was no way at all to connect to 'nwid bar'. The wireless stack would keep selecting 'nwid foo' instead. 'ifconfig iwm0 nwid bar' command will now disable automatic network selection and force the use of ESSID 'bar'. Any of these commands will re-enable automatic network selection: ifconfig iwm0 -nwid ifconfig iwm0 nwid '' ifconfig iwm0 join some-network-id ok phessler@ deraadt@

net80211: stub SIOCS80211SCAN, make ifconfig scan instant. The following removes the functionality of the SIOCS80211SCAN ioctl. After long discussions with stps@, mpi@, and deraadt@ we decided that this was the correct way of fixing ifconfig scan from blocking the network stack. The kernel will continue scanning in the background and filling the nodes array, but ifconfig scan commands will now basically do just a SIOCG80211ALLNODES and pretty print the array. So the output stays the same but is instant. In fact, when the interface is freshly brought up, if you type fast enough, you can see the array being filled by running multiple ifconfig scans in sequence. The SIOCS80211SCAN ioctl stays for now as wi(4), pgt(4) and malo(4) still need it around. But not for long... Another change that this introduces is the fact that ifconfig scan no longer plays with UP and DOWN. If the interface is down it complains and exits. This is needed in order to maintain the nodes list. Works on iwm(4), iwn(4), urtwn(4), run(4) and athn(4). Tested by mpi@, landry@, florian@, thanks! OK mpi@.

Remove global counters from struct ieee80211com which track the number of
associated nodes with particular properties: 11b-only ("non-ERP") nodes,
nodes requiring long slot time, nodes using WPA, nodes not supporting 11n,
nodes currently dozing in powersave state, and nodes with a pending group
key update confirmation.
These counters weren't properly maintained.
There are bugs in the stack where these counters and actual node properties
got out of sync. This is exposed by panics which are supposed to help us
catch such bugs. But these panics don't provide real clues.
Instead of maintaining global counters forcing us to hunt refcounting bugs,
count nodes with the property in question on demand, by iterating over all
nodes and checking their state.
This is cheap since we'll never have more than 100 nodes cached, and none of
the cases where we need such information is in a performance critical path.
Prevents panics in hostap mode reported by Lauri Tirkkonen on bugs@ last
year (https://marc.info/?l=openbsd-bugs&m=147513817930489&w=2) and also
encountered by my 11n APs ("panic: bogus non-HT station count 0").

Expose 11n mode to the ifmedia layer and introduce the concept of MCS. Make sure 11n features are enabled only if media type is autoselect or 11n. 11n mode uses MCS (modulation & coding scheme) instead of rates like 11a/b/g. This means we'll have to take the current mode into account and decide whether to use a rate or an MCS for transmission. Receiving frames on legacy rates will still work in 11n mode. We just won't be using legacy rates to send data frames to an STA or AP we negotiated 11n features with. My initial plan was to grow the ieee80211_rateset structure and treat MCS just like rates. However, ieee80211_rateset corresponds to rates and xrates elements in management frames and is copied directly into such elements so its size cannot change. Thus, MCS stands on its own and corresponds to elements in management frames related to 11n HT capabilities. ok deraadt mpi phessler kettenis guenther

Old ifconfig and dhclient binaries can still assign addresses, however the 'media' subcommand stops working. Recompiling ifconfig and dhclient with new headers before a reboot should not be necessary unless in very special circumstances where non-default media settings must be used to get link and console access is not available. There may be some MD fallout but that will be cleared up later. ok deraadt miod with help and suggestions from several sharks attending l2k15

Implement missing bits of node inactivity accounting in hostap mode. Small parts of code for this feature were already present but unused. A node becomes inactive after not sending or receiving a frame within 5 minutes. Inactive cached nodes (not authenticated or associated) are automatically cleared from the cache once every hour, making room for new nodes. If the node cache is full and room must be made for a new node, clean either a cached node (active or inactive), or an inactive authenticated or associated node. Also, do not send de-auth frames to nodes which never authenticated, and only send a de-auth frame once for a given node. This part was contributed by Steven Chamberlain, thanks!

The HT bits are currently not compiled in (IEEE80211_NO_HT is defined) because they won't be ready until after the next release and I didn't want to grow the kernel or to inadvertently introduce new bugs. They are here such that other people can look at the code. Notice that I had to add an extra parameter to ic_send_mgmt() for action frames, that is why there are small changes in drivers defining their own ic_send_mgmt() handler. Sorry for the not very incremental diff but this has been sitting in my tree for too long now.

Add ieee80211_needs_auth() function (not implemented yet) to notify the userland 802.1X PACP machine when an 802.1X port becomes enabled (that is after successfull 802.11 Open System authentication). Add SIOCS80211KEYRUN and SIOCS80211KEYAVAIL ioctls so that the PACP state machine can kick the 802.11 key state machine and install PMKs obtained from 802.1X (pre-)authentication. Enable SHA-256 based AKMPs by default while I'm here (TGw). This uses SHA-256 for key-derivation (instead of SHA1), AES-128-CMAC for data integrity, and AES Key Wrap for data protection of EAPOL-Key frames. An OpenBSD AP will always advertise this capability and an OpenBSD STA will always prefer SHA-256 based AKMPs over SHA1 based ones if both are supported by an AP.

Change the way we process EAPOL-Key frames. Free the mbuf in the ieee80211_eapol_key_input() function. Do not assume the frame is contiguous, call m_pullup2() if it is not. We need the frame to be contiguous to process KDEs efficiently in EAPOL-Key frames (just like we process IEs in management frames). However, there are drivers like upgt(4) that use m_devget() in the RX path. m_devget() can return fragmented mbuf chains. Notice that we should do the same m_pullup2() for management frames. This will be done later. Remove the ic_recv_eapol callback.

Add a new capability flag IEEE80211_C_QOS indicating that the driver supports QoS. Add a new flag IEEE80211_F_QOS indicating whether QoS is enabled or not. Add a callback to notify drivers that AC parameters have changed in the QBSS. Drivers implementing QoS should define this callback and update their EDCA settings accordingly.

add an optional max_rssi attribute to the ieee80211com structure and allow to export the RSSI Max value with ioctls and by radiotap headers. ok damien@ jsg@ description: we currently use "dB" as an indication for the signal strength in ifconfig and in the radiotap headers. it means "decibel difference from an arbitrary, fixed reference". this is quite confusing, because different chipsets have different references for the dB/rssi values. we can use the plain RSSI which is described in IEEE 802.11: "The receive signal strength indicator (RSSI) is an optional parameter that has a value of 0 through RSSI Max.". all wireless chipsets have something like a RSSI (normally as a Rx descriptor field), but the value for RSSI Max is chipset-specific. if we know the RSSI Max, we can calculate a percentage which is much easier to understand for the user. we even don't have to use the absolute RSSI Max, we can use an average RSSI Max, figured out by monitoring and tuning the RSSI Max of the drivers. if the user gets a signal of 110%, it would mean "better than the average Max signal". there's no need to do any RSSI calculations in the kernel, it just passes the the relative rssi and max_rssi values to userspace. this is done in the ieee80211_nodereq ioctl structure and possible with a new radiotap header. the radiotap RSSI header allows to get a flexible but common signal indicator instead of the complex and unrelated dB/dBm signal fields. it must include two 8bit values current rssi and RSSI max.

Improve 802.11b/g interoperability and move toward better compliance
with IEEE Std 802.11g-2003 standard:
- add ERP Information Element in probe responses and beacons
- keep track of the number of associated non-ERP STAs and non-short slot
time capable STAs in the BSS
- enable use of RTS/CTS or CTS-to-self protection when required by the BSS
- add a ic_updateslot() callback to notify drivers of slot time changes
- cleanup computation of mgmt frames sizes in ieee80211_output.c
- nuke unnecessary <sys/cdefs.h> includes
- remove an unused macro (LOGICALLY_EQUAL) while i'm here
From {free,net}bsd, with additional fixes.

derived from NetBSD: --- Make the node table into an LRU cache: least-recently used nodes are at the end of the node queue. Change the reference-counting discipline: ni->ni_refcnt indicates how many times net80211 has granted ni to the driver. Every node in the table with ni_refcnt=0 is eligible to be garbage-collected. The mere presence of a node in the table does not any longer indicate its auth/assoc state; nodes have a ni_state variable, now. While I am here, patch ieee80211_find_node_for_beacon to do a "best match" by bssid/ssid/channel, not a "perfect match." This keeps net80211 from caching duplicate nodes in the table. --- ok deraadt@ dlg@, looks good jsg@
