I noticed a possible issue in the max_tp_rate2 management of minstrel_ht. In particular, if we look up just among max_tp_rate2 of each group it will be possible that the selected rate will not be the mcs with second maximum throughput. I wrote this simple patch. Signed-off-by:

wrqu->encoding.length comes from the network administrator. It's size u16. We want to limit "tocopy" to the smallest value of either "len_keys", "wrqu->encoding.length" or 100. But because .length gets cast from u16 to u8 we might use a random, smaller value than the was desired. It's probably not very serious, but we may as well fix it. Btw, this is from code auditing and not from testing. I don't know if this affects anyone in real life. Signed-off-by:

Whenever the scan request or tx_mgmt is requesting not to use CCK rate for managemet frames through NL80211_ATTR_TX_NO_CCK_RATE attribute, then mac80211 should select appropriate least non-CCK rate. This could help to send P2P probes and P2P action frames at non 11b rates without diabling 11b rates globally. Cc: Jouni Malinen <jouni@qca.qualcomm.com> Signed-off-by:

Add a new nl80211 attribute to specify whether to send the management frames in CCK rate or not. As of now the wpa_supplicant is disabling CCK rate at P2P init itself. So this patch helps to send P2P probe request/probe response/action frames being sent at non CCK rate in 2GHz without disabling 11b rates. This attribute is used with NL80211_CMD_TRIGGER_SCAN and NL80211_CMD_FRAME commands to disable CCK rate for management frame transmission. Cc: Jouni Malinen <jouni@qca.qualcomm.com> Signed-off-by:

We returned a freed variable on some error paths when the intent was to return a NULL. Part of the reason this was missed was that the code was confusing because it had too many gotos so I removed them and simplified the flow a bit. Signed-off-by:

When we cancel a scan, the completion runs only from the workqueue. This can cause the remain-on-channel scan to fail when another one was just canceled, because we're still aborting it. To fix this, run the completion inline with the lock still held before returning from iwl_scan_cancel_timeout(). Also, to avoid the scan complete work from completing a new scan prematurely, add a new STATUS_SCAN_COMPLETE bit. Reported-by:

If iwl_scan_initiate() fails for any reason, priv->scan_request and priv->scan_vif are left dangling. This can lead to a crash later when iwl_bg_scan_completed() tries to run a pending scan request. In practice, this seems to be very rare due to the STATUS_SCANNING check earlier. That check, however, is wrong -- it should allow a scan to be queued when a reset/roc scan is going on. When a normal scan is already going on, a new one can't be issued by mac80211, so that code can be removed completely. I introduced this bug when adding off-channel support in commit 266af4c7.

Since all the queue logic has been moved to the transport layer, the sequence number is set in the transport layer. While doing that I forgot that the mac header is copied to the TB of the TX cmd in the upper layer before the call to the transport layer. So basically we used the sequence number from mac80211... This was fine for the first assocation but after the second, mac80211 resets its counters while we don't hence a shift that led to terrible impact on performance. Signed-off-by:

ieee80211_channel_to_frequency() routine expects band parameter in the form of "enum ieee80211_band band". Currently driver specific band (BAND_A, BAND_AN etc.) is passed to the routine. This patch makes sure that correct parameter is passed. Signed-off-by:

In recent commit "mwifiex: use cfg80211 dynamic scan..." (7c6fa2a8..) scan table handling in driver is removed to make use of cfg80211 dynamic scan table. Now driver sends beacon buffers found in scanning directly to stack and parse the buffer for requested BSS only during association. Beacon buffer doesn't contain bss band information. Driver gets it from firmware in separate tlv (chan_band_tlv). Currently since we don't inform stack about bss bandinfo, there is an issue with 5GHz association. Use "priv" field of struct cfg80211_bss to store bandinfo. This fixes 5GHz association issue. Signed-off-by:

Sometimes association in 5GHz doesn't work. Dmesg log shows "Can not find requested SSID xyz" error message. Currently while preparing scan channel list for firmware Null entries are created for disabled channels. The routine which retrieves this list ignores channels after Null entry. Hence sometimes driver doesn't scan the channel of requested AP and association fails. The issue is fixed by avoiding those NULL entries. Signed-off-by:

When scanning for the broadcast SSID, there is no need to add the SSID TLV (restoring the behaviour of the driver behaviour in the wext days, confirmed in Marvell specifications). If bssid is unspecified, the current scan code will usually fire off an active scan probing for the specific requested SSID. However, if a scan is ongoing (or has just finished), those scan results will be used instead (even if that scan is totally different, e.g. a passive scan on channel 4 for a different SSID). Fix this inconsistency by always firing off a scan when associating without a bssid. Signed-off-by:

Instead of using a hardcoded list of cipher suites in nl80211.c, use a shared function in util.c to verify that the driver advertises support for the specified cipher. This provides more accurate validation of the values and allows vendor-specific cipher suites to be added in drivers. Signed-off-by:

NL80211_ATTR_AKM_SUITES can be used to configure new AKMs, like FT or the SHA-256 -based AKMs or FT from 802.11r/802.11w. In addition, vendor specific AKMs could be used. The current validation code for the connect command prevents cfg80211-based drivers from using these mechanisms even if the driver would not actually use this AKM value (i.e., it uses WPA/RSN IE from user space). mac80211-based drivers allow any AKM to be used since this value is not used there. Remove the unnecessary validation step in cfg80211 to allow drivers to decide what AKMs are supported. In theory, we could handle this by advertising supported AKMs, but that would not be very effective unless we enforce all drivers (including mac80211) to advertise the set of supported AKMs. This would require additional changes in many places whenever a new AKM is introduced even though no actually functionality changes may be required in most drivers.
