This patch adds tx queue mapping for rtl8187se and a long comment block about their usages. It adapts the TX function to use that map and it sets properly the TX descriptor rtl8187se-only fields Signed-off-by:

Currently RX status descriptor and RX command descriptor are represented using the same struct type. This patch splits this by introducing different types for rx status and command descriptor. Doing this make it possible to handle rtl8187se RX descriptors easier. This patch do also this by adding specific cases where needed. Signed-off-by:

When next scan command is delayed due to Tx traffic and meanwhile synchronous command is received followed by a signal, we cance all pending commands. NULL pointer dereference is seen in this case while queueing next command in scan delay timer. This patch adds a check to fix this issue. Signed-off-by:

The struct cfg80211_connect_params indicate whether the connection should use management frame protection (mfp). If required set the MFP_CAPABLE flag in the firmware command. This is supported from user-space by wpa_supplicant since v2.1. Reviewed-by:

On currently supported HW there are four TX queues (three for normal packets and one for beacons). The driver uses just one TX queue, and declare to mac80211 to support just one queue, but it allocates coherent memory for all queues. Furthermore the TX is code is written assumimg four queues exists, and even if we decide to enable more queues in future, its mapping rule to mac80211 is fixed. This means we have memory waste on rtl8180/rtl8185, and we have also not enough flexibility to add support for boards (rtl8187se) that will use more queues. This patch changes things in order to allocate coherent memory only for the queues effectively used and it make it possible to specify how to map hardware queues on mac80211 queues, that will be used by rtl8187se code as soon it will be merged. Note: even if the beacon queue is currently unused, this should change, so I kept it. Signed-off-by:

Hw DMA registers are written in rtl8180_init_hw function. They are also written again just after calling rtl8180_init_hw. There is no point in doing this twice. Remove those redundant register writes from rtl8180_start. Signed-off-by:

We should let user space request the peer address also in the pending connect states, i.e. BT_CONNECT and BT_CONNECT2. There is existing user space code that tries to do this and will fail without extending the set of allowed states for the peer address information. This patch adds the two states to the allowed ones in the L2CAP and RFCOMM sock_getname functions, thereby preventing ENOTCONN from being returned. Reported-by:

The smp variable in smp_conn_security is not used anywhere before the smp = smp_chan_create() call in the smp_conn_security function so it makes no sense to assign any other value to it before that. Signed-off-by:
-
Johan Hedberg authored
The smp pointer might not be initialized for jumps to the "done" label in the smp_conn_security function. Furthermore doing the set_bit after done might "overwrite" a previous value of the flag in case pairing was already in progress. This patch moves the call to set_bit before the label so that it is only done for a newly created smp context (as returned by smp_chan_create). Signed-off-by:

Due to several devices being unable to handle this procedure reliably (resulting in forced disconnections before pairing completes) it's better to remove it altogether. Signed-off-by:

In the case that the just-works model would be triggered we only want to confirm remotely initiated pairings (i.e. those triggered by a Security Request or Pairing Request). This patch adds the necessary check to the tk_request function to fall back to the JUST_WORKS method in the case of a locally initiated pairing. Signed-off-by:

For remotely initiated just-works pairings we want to show the user a confirmation dialog for the pairing. However, we can only know which side was the initiator by tracking which side sends the first Security Request or Pairing Request PDU. This patch adds a new SMP flag to indicate whether our side was the initiator for the pairing. Signed-off-by:

In the case that a local pairing confirmation (JUST_CFM) has been selected as the method we need to use the user confirm request mgmt event for it with the confirm_hint set to 1 (to indicate confirmation without any specific passkey value). Without this (if passkey_notify was used) the pairing would never proceed. This patch adds the necessary call to mgmt_user_confirm_request in this scenario. Signed-off-by:

It is possible that the HCI_LE_Start_Encryption command fails in an early stage and triggers a command status event with the failure code. In such a case we need to properly notify the hci_conn object and cleanly bring the connection down. This patch adds the missing command status handler for this HCI command. Signed-off-by:

We need to ensure that we do not send events to user space with the identity address if we have not yet notified user space of the IRK. The code was previously trying to handle this for the mgmt_pair_device response (which worked well enough) but this is not the only connection related event that might be sent to user space before pairing is successful: another important event is Device Disconnected. The issue can actually be solved more simply than the solution previously used for mgmt_pair_device. Since we do have the identity address tracked as part of the remote IRK struct we can just copy it over from there to the hci_conn struct once we've for real sent the mgmt event for the new IRK.

The watchdog thread waits on completion that is set from a timer. As the completion is count based this could mean that on a busy system the watchdog is handled multiple times with a very short interval. This is not the intended behaviour. After handling the watchdog it should wait for the next timer expiry. This is accomplished by reinitializing the completion. Reviewed-by:
