* rtlwifi: rtl8192se: Handle duplicate PCI ID 0x10ec:0x8192 conflict with ↵Larry Finger2011-06-201-1/+12
| | | | | | | | | | | | r8192e_pci There are two devices with PCI ID 0x10ec:0x8192, namely RTL8192E and RTL8192SE. The method of distinguishing them is by the revision ID at offset 0x8 of the PCI configuration space. If the value is 0x10, then the device uses rtl8192se for a driver.

| | | | | | | | | | | In the case we fail to allocate a new skb, the old skb should be resubmitted unmodified. Fixes bug introduced in a9e12869758430424804.

* rtlwifi: Use order 2 RX buffer allocation only if necessaryLarry Finger2011-05-261-0/+7
| | | | | | | | | | Although a previous fix handles the kernel panics that result from failure to allocate a new RX buffer, memory fragmentation can be reduced if the amsdu_8k capability is disabled as new buffers need only be of O(0), not O(2).

* rtlwifi: Fix kernel panic resulting from RX buffer allocation failureLarry Finger2011-05-261-13/+15
| | | | | | | | | | | | | | | | | To handle amsdu_8k capability, the PCI routine of this driver must allocate receive buffers of order 2. Under heavy load, this causes fragmentation of memory. The present code releases the current buffer before checking to see if a new one is availble. Recovery from allocation failures is not possible, which results in kernel panics. The fix is to reorder the code to check that a new buffer can be allocated before the old one is released. If not possible, the received frame is dropped and the old one is reused. Without this change, it is impossible to transfer a 2 GB file without a kernel panic.

* rtlwifi: Fix possible NULL dereferenceJesper Juhl2011-01-211-2/+9
| | | | | | | | | | | | | | | In drivers/net/wireless/rtlwifi/pci.c::_rtl_pci_rx_interrupt() we call dev_alloc_skb(), which may fail and return NULL, but we do not check the returned value against NULL before dereferencing the returned pointer. This may lead to a NULL pointer dereference which means we'll crash - not good. In a separate call to dev_alloc_skb(), the debug level is changed so that the failure message will always be logged.
