2014-02-06rtlwifi: Increase the RX queue length for USB driversLarry Finger
commit dc6405712268fe514d3dd89aa936c4397b0871b9 upstream. The current number of RX buffers queued is 32, which is too small under heavy load. That number is doubled.

2013-08-04rtlwifi: Initialize power-setting callback for USB devicesLarry Finger
commit bcfb879432094c267c35a7ff75d953d3a66c193a upstream. Commit a269913c5 entitled "rtlwifi: Rework rtl_lps_leave() and rtl_lps_enter() to use work queue" has two bugs for USB drivers. Firstly, the work queue in question was not initialized. Secondly, the callback routine used by this queue is contained within the file used for PCI devices. As a result, it is not available for architectures without PCI hardware.

separately rtlwifi allocates both setup_packet and data buffer of control message urb, using shared kmalloc in _usbctrl_vendorreq_async_write. Structure used for allocating is: struct { u8 data[254]; struct usb_ctrlrequest dr; }; Because 'struct usb_ctrlrequest' is __packed, setup packet is unaligned and DMA mapping of both 'data' and 'dr' confuses ARM/sunxi, leading to memory corruptions and freezes.

2012-07-12rtlwifi: rtl8192cu: Change buffer allocation for synchronous readsLarry Finger
In commit a7959c1, the USB part of rtlwifi was switched to convert _usb_read_sync() to using a preallocated buffer rather than one that has been acquired using kmalloc. Although this routine is named as though it were synchronous, there seem to be simultaneous users, and the selection of the index to the data buffer is not multi-user safe. This situation is addressed by adding a new spinlock. The routine cannot sleep, thus a mutex is not allowed.

In commit b0302ab, the rtlwifi family of drivers was converted to use asynchronous firmware loading. Unfortumately, the implementation was racy, and the ieee80211 routines could be started before rtl_init_core() was called to setup the data.

2012-04-11rtlwifi: Preallocate USB read buffers and eliminate kalloc in read routineLarry Finger
The current version of rtlwifi for USB operations uses kmalloc to acquire a 32-bit buffer for each read of the device. When _usb_read_sync() is called with the rcu_lock held, the result is a "sleeping function called from invalid context" BUG. This is reported for two cases in https://bugzilla.kernel.org/show_bug.cgi?id=42775. The first case has the lock originating from within rtlwifi and could be fixed by rearranging the locking; however, the second originates from within mac80211. The kmalloc() call is removed from _usb_read_sync() by creating a ring buffer pointer in the private area and allocating the buffer data in the probe routine.

2012-03-05rtlwifi: Remove extraneous value returnLarry Finger
In usb.c, routine _rtl_usb_init_sw() always returns 0, and rtl_usb_probe() never checks the returned value. Thus we can change _rtl_usb_init_sw() to a void routine.

2012-01-30rtlwifi: Convert to asynchronous firmware loadLarry Finger
This patch addresses a kernel bugzilla report and two recent mail threads. The kernel bugzilla report is https://bugzilla.kernel.org/show_bug.cgi?id=42632, which reports a udev timeout on boot. The first mail thread, which was on LKML (http://lkml.indiana.edu/hypermail/ linux/kernel/1112.3/00965.html) was for a WARNING that occurs after a suspend/resume cycle for rtl8192cu. The scond mail thread (http://marc.info/?l=linux-wireless&m=132655490826766&w=2) concerned changes in udev that break drivers that delay while firmware is loaded on modprobe. This patch converts all rtlwifi-based drivers to use the asynchronous firmware loading mechanism. Drivers rtl8192ce, rtl8192cu and rtl8192de share a common callback routine. Driver rtl8192se needs different handling of the firmware, thus it has its own code. Signed-off-by: Larry Finger <Larry.Finger@lwfinger.net> Cc: Stable <stable@vger.kernel.org> Signed-off-by: John W.
