| * rtlwifi: Fix kernel Oops "Fw download fail!!"Ping-Ke Shih2018-06-24

This will cause unpredictable kernel oops or crash like rtl8723be: error H2C cmd because of Fw download fail!!!

This patch ensures all delayed works done before entering PS to satisfy our expectation, so use cancel_delayed_work_sync() instead. An exception is delayed work ips_nic_off_wq because running task may be itself, so add a parameter ips_wq to deinit function to handle this case.

* rtlwifi: fix btmpinfo timeout while processing C2H_BT_INFOPing-Ke Shih2018-05-29
| | | | | | | | | | | | | | In former patch, I enqueu all C2H commands and processed by a workqueue. In case C2H_BT_INFO will issue a H2C command to set BT reg, and wait for a C2H ack. But it is totally impossible that C2H workqueue waits for a C2H command, so kernel log warn rtlwifi: :<0> btmpinfo wait (req_num=0) timeout Since the C2H ack command C2H_BT_MP can be safely processed in interrupt context, add a fast command path to deal with the command.

Since C2H commands are asynchronous events, they can be processed in work queue, so RX ISR enqueues C2H result in removal of rtl_c2h_packet_handler().

* rtlwifi: support accurate nullfunc frame tx ack reportTzu-En Huang2018-05-29
| | | | | | | | | | | | | | | | | In order to realize the keep-alive mechanism in mac80211 stack, reporting accurate tx ack status for nullfunc frame is added in this commit. If current frame is nullfunc frame, we ask firmware to report by filling TX report bit in TX descriptor. After this frame DMA done, TX interrupt is triggered but TX status is unknown at this moment, so enqueue this skb into tx_report->queue. Finally, C2H report will be received if the frame is transmitted successfully or retried over, and then we report to mac80211 with IEEE80211_TX_STAT_ACK flag only if it's successful. Otherwise, if failure or timeout (one second), we report to mac80211 without this flag.

* rtlwifi: Use mutex to replace spin_lock to protect IPS and LPSPing-Ke Shih2018-01-17
| | | | | | | | | | | | | | | | | | 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>

What makes me happy that we have now more vendors actively contributing to upstream drivers. In this pull request we have patches from Broadcom, Intel, Qualcomm, Realtek and Redpine Signals, and I still have patches from Marvell and Quantenna pending in patchwork. Now that's something comparing to how things looked 11 years ago in Jeff Garzik's "State of the Union: Wireless" email: https://lkml.org/lkml/2006/1/5/671 Major changes: wil6210 * add low level RF sector interface via nl80211 vendor commands * add module parameter ftm_mode to load separate firmware for factory testing * support devices with different PCIe bar size * add support for PCIe D3hot in system suspend * remove ioctl interface which should not be in a wireless driver ath10k * go back to using dma_alloc_coherent() for firmware scratch memory * add per chain RSSI reporting brcmfmac * add support multi-scheduled scan * add scheduled scan support for specified BSSIDs * add support for brcm43430 revision 0 wlcore * add wil1285 compatible rsi * add RS9113 USB support iwlwifi * FW API documentation improvements (for tools and htmldoc) * continuing work for the new A000 family * bump the maximum supported FW API to 31 * improve the differentiation between 8000, 9000 and A000 families ==================== Signed-off-by: David S.

When msg 3/4 is received, the supplicant will send msg 4/4 and install the new key immediately; however, the driver must make sure that msg 4/4 is sent before installing the new key.

* rtlwifi: Convert COMP_XX entries into a proper debugging maskLarry Finger2017-01-20
| | | | | | | | | | | | | | | | | | The debugging macros contain a parameter COMP_XX that could be used as a mask; however, the code turns all these various bits on at the same time. This change implements them as a proper mask, and adds module parameters to set the mask at load time. The current name "debug" for the debug level has been changed to "debug_level" to better differentiate it from "debug_mask". The debug routines have also been changed to interrogate the structure that is loaded at entry time. As a result, the structure rtl_debug is no longer needed, and all references to it are deleted.
