2018-01-24rtlwifi: btcoex: Add wifi_only series ops to control solo cardPing-Ke Shih
Originally, btcoex controls the antenna of combo card, but solo card is also needed to setup properly. The new ops are named with suffix '_wifi_only' opposited to original btc_ops, and new structures and definitions are also introduced. The wifi_only oly contains four ops that are initial variable, hw config, scan notify, and switch band notify.

2018-01-24mt76: fix transmission of encrypted management framesFelix Fietkau
Hardware encryption seems to break encrypted unicast mgmt tx. Unfortunately the hardware TXWI header does not have a bit to indicate that a frame is software encrypted, so sw-encrypted frames need to use a different WCID. For that to work, the CCMP PN needs to be generated in software, which makes things a bit slower, so only do it for keys that also need to tx management frames.

2018-01-17rtlwifi: Use mutex to replace spin_lock to protect IPS and LPSPing-Ke Shih
Enter/leavel IPS and LPS are large critical section, and they can't use sleep function because running in atomic-context, which own a spin_lock. In commit ba9f93f82aba ("rtlwifi: Fix enter/exit power_save"), it moves LPS functions to thread-context, so this commit can simply change LPS's spin lock to mutex. Considering IPS functions, rtl_ips_nic_on() may be called by TX tasklet (softirq-context) that check whether packet is auth frame. Fortunately, current mac80211 will ask driver to leave IPS using op_config with changed flag IEEE80211_CONF_CHANGE_IDLE, before issuing auth frame, so IPS functions can run in thread-context and use mutex to protect critical section, too. Also, this commit removes some useless spin locks. Signed-off-by: Ping-Ke Shih <pkshih@realtek.com> Signed-off-by: Kalle Valo <kvalo@codeaurora.org>

For legacy chips without CLM blob files, kernel with user helper function returns -EAGAIN when we request_firmware(), and then driver got failed when bringing up legacy chips. We expect the CLM blob file for legacy chip is not existence in firmware path, but the -ENOENT error is transferred to -EAGAIN in firmware_class.c with user helper. Because of that, we continue with CLM data currently present in firmware if getting error from doing request_firmware().

2018-01-16mwifiex: resolve reset vs. remove()/shutdown() deadlocksBrian Norris
Commit b014e96d1abb ("PCI: Protect pci_error_handlers->reset_notify() usage with device_lock()") resolves races between driver reset and removal, but it introduces some new deadlock problems. If we see a timeout while we've already started suspending, removing, or shutting down the driver, we might see: (a) a worker thread, running mwifiex_pcie_work() -> mwifiex_pcie_card_reset_work() -> pci_reset_function() (b) a removal thread, running mwifiex_pcie_remove() -> mwifiex_free_adapter() -> mwifiex_unregister() -> mwifiex_cleanup_pcie() -> cancel_work_sync(&card->work) Unfortunately, mwifiex_pcie_remove() already holds the device lock that pci_reset_function() is now requesting, and so we see a deadlock. It's necessary to cancel and synchronize our outstanding work before tearing down the driver, so we can't have this work wait indefinitely for the lock. It's reasonable to only "try" to reset here, since this will mostly happen for cases where it's already difficult to reset the firmware anyway (e.g., while we're suspending or powering off the system). And if reset *really* needs to happen, we can always try again later.

2018-01-16Revert "mwifiex: cancel pcie/sdio work in remove/shutdown handler"Brian Norris
This reverts commit b713bbf1471b56b572ce26bd02b81a85c2b007f4. The "fix" in question does not actually fix all related problems, and it also introduces new deadlock possibilities. Since commit b014e96d1abb ("PCI: Protect pci_error_handlers->reset_notify() usage with device_lock()"), the race in question is actually resolved (PCIe reset cannot happen at the same time as remove()). Instead, this "fix" just introduces a deadlock where mwifiex_pcie_card_reset_work() is waiting on device_lock, which is held by PCIe device remove(), which is waiting on...mwifiex_pcie_card_reset_work(). The proper thing to do is just to fix the deadlock. Patch for this will come separately.

This patch adds a rhastable for mac address lookup of hwsim radios. This especially improve the speed on reception of a netlink message with a new frame. Although redundant, we keep holding a normal list for all radios, since the rhashtable_walk interface adds a lot of overhead for iterating over all radios and the doc of rhashtable recommend a redundant structure for stable walks in such situations. Since rhashtable is rcu protected we do not need a lock for delivering frames and thus improving this scenario.
