Scanning is curently broken when two channel contexts are active. For example in a P2P-GO/STA setup, the offchannel timer allows HZ / 10 to elapse before initiating a switch to the next scan channel from the current operating channel, which in this case would be the P2P-GO context. But, the channel context timer might decide to switch to the STA context when an SWBA comes early and a beacon is sent out. Since pending offchannel requests are processed in EVENT_BEACON_PREPARE, this causes inconsistent scanning. Fix this by making sure that a context switch happens before processing the pending offchannel request. This also makes sure that active channel contexts will always have higher priority than offchannel operations and the scan sequence looks like this: p2p-go, sta, p2p-go, offchannel, p2p-go, sta, p2p-go, offchannel,..... The oper-channel is p2p-go, so the STA context has to switch to p2p-go again before switching offchannel. Signed-off-by: Sujith Manoharan <c_manoha@qca.qualcomm.com> Signed-off-by: John W.

When multiple channel contexts are active, an offchannel request will not be handled immediately, but will be queued to be handled later. But, currently, the channel definition is not copied to the local offchannel state. This breaks operation like scanning when MCC is active. Fix this by storing the offchannel parameters properly.

If multiple channel contexts are active, then the opmode can be different in each context. Since the RX filter is calculated in ath_startrecv() before switching to the new opmode, the wrong filters are chosen.

Currently, different units are used for handling sc->offchannel.duration. In scan mode, it contains jiffies and in RoC mode, milliseconds is used. This causes confusion since in ath_chanctx_switch(), TU_TO_USEC is used to determine the offchannel duration, resulting in incorrect values. Fix this by using jiffies in both modes.

The start time field in the NoA attribute needs to be updated based on the TSF timer when an absence notification is sent by the P2P GO. When two channel contexts are active, continuous, cyclic NoA is announced by setting the count value to 255, but the start time is updated only once, for one beacon and the same value is sent in all subsequent beacons, even though the timestamp keeps moving. Fix this by removing the check for 'periodic_noa_duration' and assign the interface's start_time/duration values directly when there is more than one active context.

If a station interface is already assigned to a context and is active and a second interface of type AP is added, then beaconing on the new interface has to be begin only after the BSS_CHANGED_BEACON_ENABLED flag is sent by mac80211 to the driver. But, since we issue ATH_CHANCTX_EVENT_ENABLE_MULTICHANNEL as soon as a new channel context is added, a switch occurs almost immediately before BSS_CHANGED_BEACON_ENABLED is received. When a HW reset is done for the new context, beacons are enabled for the interface since "enable_beacon" in the BSS config maintained in mac80211 is true - but the driver hasn't been notified yet. This causes a panic, since the beacon interval is zero for this interface and ath9k_cmn_beacon_config_ap() doesn't have a safety check. Fix this panic by checking if the beacon params has been cached for this context and use the "enable_beacon" flag maintained locally in the driver. Also, recalculate the summary data after the beacon params have been cached when BSS_CHANGED_BEACON_ENABLED is received.

In channel context mode, when a new context is added, mac80211 issues a bss_info_changed() notfication when preparing the connection for the new interface/context. But, this is done prior to the mgd_prepare_tx() call which is where we switch to the new context. Since the current context will be different when the earlier bss_info_changed() is handled, the beacon information for the VIF is not updated, but discarded since the rules for the current context disallows it. In the subsequent association process for the new context/vif, this becomes a problem because the beacon parameters are invalid. This causes problems with the TSF timer, causing large jumps. To fix this, check if the beacon info is being updated for a different context and if so, allow it without any checks since we limit the max. interfaces to two anyway.

Replaced the use of a Variable Length Array In Struct (VLAIS) with a C99 compliant equivalent. This patch allocates the appropriate amount of memory using an char array. The new code can be compiled with both gcc and clang. struct shash_desc contains a flexible array member member ctx declared with CRYPTO_MINALIGN_ATTR, so sizeof(struct shash_desc) aligns the beginning of the array declared after struct shash_desc with long long. No trailing padding is required because it is not a struct type that can be used in an array. The CRYPTO_MINALIGN_ATTR is required so that desc is aligned with long long as would be the case for a struct containing a member with CRYPTO_MINALIGN_ATTR.

SMP defines quite clearly when certain PDUs are to be expected/allowed and when not, but doesn't have any explicit request/response definition. So far the code has relied on each PDU handler to behave correctly if receiving PDUs at an unexpected moment, however this requires many different checks and is prone to errors. This patch introduces a generic way to keep track of allowed PDUs and thereby reduces the responsibility & load on individual command handlers. The tracking is implemented using a simple bit-mask where each opcode maps to its own bit. If the bit is set the corresponding PDU is allow and if the bit is not set the PDU is not allowed. As a simple example, when we send the Pairing Request we'd set the bit for Pairing Response, and when we receive the Pairing Response we'd clear the bit for Pairing Response. Since the disallowed PDU rejection is now done in a single central place we need to be a bit careful of which action makes most sense to all cases. Previously some, such as Security Request, have been simply ignored whereas others have caused an explicit disconnect. The only PDU rejection action that keeps good interoperability and can be used for all the applicable use cases is to drop the data. This may raise some concerns of us now being more lenient for misbehaving (and potentially malicious) devices, but the policy of simply dropping data has been a successful one for many years e.g. in L2CAP (where this is the *only* policy for such cases - we never request disconnection in l2cap_core.c because of bad data). Furthermore, we cannot prevent connected devices from creating the SMP context (through a Security or Pairing Request), and once the context exists looking up the corresponding bit for the received opcode and deciding to reject it is essentially an equally lightweight operation as the kind of rejection that l2cap_core.c already successfully does.

When we're in the process of receiving keys in phase 3 of SMP we keep track of which keys are still expected in the smp->remote_key_dist variable. If we still have some key bits set we need to continue waiting for more PDUs and not needlessly call smp_distribute_keys(). This patch fixes two such cases in the smp_cmd_master_ident() and smp_cmd_ident_addr_info() handler functions.
