IE's are parsed from beacon buffer and stored locally using mwifiex_update_bss_desc_with_ie() function. Sometimes the local pointers point to the data inside IE, but while using them it is assumed that they are pointing to the IE itself. These issues are fixed in this patch. Signed-off-by:

This option allows driver to finish pending operations in disconnect handler by not killing URBs after usb_deregister call. We will get rid of global pointer 'usb_card' by moving code from cleanup_module() to disconnect(). This will help to match with our handling for SDIO and PCIe interfaces. Signed-off-by:

For PCIe, aggregate more AMSDU packets till PCIe TXBD is full. For SDIO, aggregation was disabled for AMSDU packets because AMSDU aggregated packet size is already 4K or 8K, SDIO Multiport Aggregation feature didn't use to gain much previously. Now with increased multiport aggregation buffer, we can enable it for AMSDU packets. Signed-off-by:

Currently Tx and Rx buffer sizes are 8K and 16K respectively for all chipsets. We will change them to 32K for SD8897 and 16K for older chipsets. SD8897 chipset has more SDIO data ports than older chipsets. This patch will help to improve throughput numbers. Signed-off-by:

Sometimes, due to the race between Rx path and WMI_BA_STATUS_EVENTID WMI event, few frames may be passed to the stack before reorder buffer allocated. Then, after BACK establishment, it start getting frames with sequence number ahead of SSN, and it get interpreted as missing frames. Then, BACK mechanism will wait for missing frames; data traffic will be stopped. In case of interface configured for DHCP, this data delay causes DHCP failure. Relax checking for sequence number; use sequence of 1-st frame handled by the buffer as SSN for this buffer. This is work-around, real fix should be done when proper BACK mechanism implemented.

HW should never attempt to perform DMA for unused queues. For rtl8187se this is ensured by setting a dedicated register at init time, before enabling TX. In rtl8180/5 the register is only written at the first TX (because in rtl8180/5 it serves also to kick DMA for used queues). This should be enough, but it's worth to add a register write at init time, before enabling TX. Signed-off-by:

Parentheses are missing around the macro argument, causing the macro possibly not to work passing certain expressions as arguments. This should not cause any issues with current code, however it's worth to add them, as a good practice, and to eventually avoid future bugs. Suggested-by:

When preparing the bitfield to write to HW register, the high-priority queue error interrupt bit is set two times, and the beacon queue TX-OK interrupt is not enabled. Currently this have no functional impact because the high-priority queue is not used at all, and the beacon queue is not used yet. This patch removes high-priority queue bits and it adds the beacon queue missing bit. It removes also the management queue bits because it is not used. This was found by static code analyzer.

rtl8180 driver can handle also rtl8185 and rtl8187SE cards, however in userspace tools (network manager) it still appares as "rtl8180". This might lead the user to think the wrong driver is in use. This patch changes module name to "rtl818x_pci" that should be more explanatory. Signed-off-by: Larry Finger <Larry.Finger@lwfinger.net> [ original patch ] Signed-off-by:

This buffer over was detected using static analysis: drivers/isdn/icn/icn.c:1325 icn_command() error: format string overflow. buf_size: 60 length: 98 The calculation for the length of the string is off because it assumes that the dial[] buffer holds a 50 character string, but actually it is at most 31 characters and NUL. I have removed the dial[] buffer because it isn't needed. The maximum length of the string is actually 79 characters and a NUL. I have made the cbuf[] array large enough to hold it and changed the sprintf() to an snprintf() as a further safety enhancement. Signed-off-by:

Guenter Roeck says: ==================== net: mdio-gpio enhancements The following series of patches adds support for active-low gpio pins as well as for systems with separate MDI and MDO pins to the mdio-gpio driver. A board using those features is based on a COM Express CPU board. The COM Express standard supports GPIO pins on its connector, with one caveat: The pins on the connector have fixed direction and are hard configured either as input or output pins. The COM Express Design Guide [1] provides additional details. The hardware uses three of the GPO/GPI pins from the COM Express board to drive an MDIO bus. Connectivity between GPI/GPO pins and the MDIO bus is as follows. GPI2 --------------------+------------ MDIO | +--------+ | GPO2 ---+---G | | | | | | 4.7k | 2N7002 D---+ | | | +---S | | +--------+ GND GPO1 --------------------------------- MDC To support this hardware, two extensions to the driver were necessary. - Due to the FET in the MDO path (GPO2), the MDO signal is inverted. The driver therefore has to support active-low GPIO pins. - The MDIO signal must be separated into MDI and MDO. Those changes are implemented in patch 2/3 and 3/3. Patch 1/3 simplifies the error path and thus the subsequent patches. [1] http://www.picmg.org/pdf/picmg_comdg_100.pdf ==================== Signed-off-by:
