qtnfmac: do not use bus mutex for events processing

2018-01-24T16:00:55Z

Events processing requires locking of bus mutex, which is also used by cfg80211 layer before calling several of cfg80211 callbacks. Since all cfg80211 callbacks in qtnfmac driver also lock bus mutex, this potentially may lead to a deadlock. Do not use bus lock for event processing. Use RTNL lock instead to serialize events and commands processing threads. Signed-off-by: Igor Mitsyanko Signed-off-by: Kalle Valo

qtnfmac: do not use mutexes in timer context

2018-01-24T16:00:54Z

The function qtnf_scan_done makes use of mutexes which is wrong since it may be called from timer context. Move scan timeout handler from timer to deferred work. Signed-off-by: Igor Mitsyanko Signed-off-by: Kalle Valo

qtnfmac: fix STA disconnect procedure

2018-01-24T16:00:50Z

STA does not reconnect to the same AP after disconnect. The reason is that STA is marked as disconnected in cfg80211 disconnect callback. This is too early since in this case qtnfmac event handler skips cfg80211_disconnected call when processing disconnect event from the card. As a result, wdev is left in an inconsistent state.

qtnfmac: validate interface combinations on changes

2018-01-24T16:00:45Z

Validate new interface combinations using wireless core checks when new interface is added or when the type of existing interface is modified. This is performed to make sure that new interface combination is supported by hardware. As a result, invalid interface combinations are rejected early, rather than passed to hardware with sometimes unpredictable results. Signed-off-by: Sergey Matyukevich Signed-off-by: Kalle Valo

qtnfmac: modify supported interface combinations

2018-01-24T16:00:40Z

Update existing code handling configuration of supported interface combinations. Current implementation is not complete since it does not report multiple interface combinations which are incompatible with each other. Instead current implementation packs all the supported combinations into single entry. In fact currently qsr10g wireless card supports the following two distinct interface combinations: 1. STA/repeater: 1 STA and/or 1 AP { { .max = 1, .types = NL80211_IFTYPE_AP}, { .max = 1, .types = NL80211_IFTYPE_STA}, } 2. AP/mBSS { { .max = 8, .types = NL80211_IFTYPE_AP}, } The list of supported configuration is reported by firmware during wireless card bring-up. Communication protocol between firmware and host has been updated accordingly in order to accommodate passing multiple interface combination entries.

qtnfmac: report hardware/firmware information via ethtool

qtnfmac: get more hardware info from card

2018-01-24T16:00:33Z

Various bits of hardware and firmware versions are useful for debug and troubleshooting. Get more information from the wireless card. Signed-off-by: Vasily Ulyanov Signed-off-by: Kalle Valo

qtnfmac: support 64-bit network interface stats

2018-01-24T16:00:30Z

On 32-bit platforms packet counters are stored in a net_device_stats struct as unsigned long integers. As a result, after some time of network activity an overflow takes place in network packet counters. This patch makes use of new structs for holding interface statistics.

qtnfmac: fix warnings when mBSS setup is stopped

2018-01-24T16:00:26Z

Virtual interface should be deleted after calling unregister_netdevice since this function ends up with sending updown_intf command to card. Signed-off-by: Vasily Ulyanov Signed-off-by: Kalle Valo
