commit da849a92d3bafaf24d770e971c2c9e5c3f60b5d1 upstream. The ISY IWL 1000 USB WLAN stick with USB ID 050d:11f1 is a clone of the Belkin F7D1101 V1 device. Reported-by: Thomas Hartmann Signed-off-by: Larry Finger Cc: Thomas Hartmann Signed-off-by: Greg Kroah-Hartman

staging: r8712u: Do not queue cloned skb

2012-10-07T15:32:24+00:00

commit fa16e5ea25d7dd83f663f333e70713aa2fa5dffe upstream. Some post-3.4 kernels have a problem when a cloned skb is used in the RX path. This patch handles one such case for r8712u. The patch was suggested by Eric Dumazet. Signed-off-by: Larry Finger Signed-off-by: Greg Kroah-Hartman

staging: r8712u: fix bug in r8712_recv_indicatepkt()

commit abf02cfc179bb4bd30d05f582d61b3b8f429b813 upstream. 64bit arches have a buggy r8712u driver, let's fix it. skb->tail must be set properly or network stack behavior is undefined.

staging: r8712u: Fix Smatch warning

2012-03-07T21:36:45+00:00

The patch 2080913e017a: "staging: r8712u: Fix regression caused by commit 8c213fa" from Feb 25, 2012, leads to the following Smatch complaint: drivers/staging/rtl8712/usb_intf.c:629 r871xu_dev_remove() warn: variable dereferenced before check 'padapter' (see line 625) The fix is to move the new statements inside the block where padapter is not NULL.

Staging: rtl8712/rtl8192u: move USB device ID within staging drivers.

2012-03-03T00:36:38+00:00

It seems the USB device ID 0bda:8192 is wrongly assigned to the RTL8192SU chip and not to the RTL8191SU chip in the USB database. So this patch moves this device ID from the rtl8192u staging driver to the rtl8712 staging driver. This patch was tested with a Radicom WIFIHU embedded wireless module with a RTL8191SU chip and the USB device ID 0bda:8192. Without the patch the rtl8192u driver claims this device, but it does not work. With the patch the rtl8712 driver services this device and it works.

Staging rtl8712: Remove double USB device IDs

staging: r8712u: Fix regression in signal level after commit c6dc001

2012-03-01T00:28:56+00:00

In commit c6dc001 "staging: r8712u: Merging Realtek's latest (v2.6.6). Various fixes", the returned qual.qual member of the iw_statistics struct was changed. For strong signals, this change made no difference; however for medium and weak signals it results in a low signal that shows considerable fluctuation, When using wicd for a medium-strength AP, the value reported in the status line is reduced from 100% to 60% by this bug. This problem is reported in https://bugzilla.kernel.org/show_bug.cgi?id=42826. Reported-and-tested-by: Robert Crawford Signed-off-by: Larry Finger Cc: Stable Signed-off-by: Greg Kroah-Hartman

staging: r8712u: Fix regression caused by commit 8c213fa

2012-03-01T00:28:51+00:00

In commit 8c213fa "staging: r8712u: Use asynchronous firmware loading", the command to release the firmware was placed in the wrong routine. In combination with the bug introduced in commit a5ee652 "staging: r8712u: Interface-state not fully tracked", the driver attempts to upload firmware that had already been released. This bug is the source of one of the problems in https://bugs.archlinux.org/task/27996#comment89833.

staging: r8712u: Fix regression introduced by commit a5ee652

2012-03-01T00:28:50+00:00

In commit a5ee652 "staging: r8712u: Interface-state not fully tracked", the private boolean "bup" was set false when the interface was brought down, as that seemed appropriate. This change has not caused any problems when using NetworkManager or manual control of the device; however, when wicd control is used, there is a locking problem in wpa_supplicant, as shown in https://bugzilla.kernel.org/show_bug.cgi?id=42818. This fix reverts the only code change in commit a5ee652. My analysis is that "bup" is badly named. In its present form, it seems to indicate the up/down state of the device, but its usage is more consistent with an initialized/uninitialized state. That problem will be addressed in a later patch. Note: Commit 8c213fa, which introdued asynchronous firmware loading for this driver, exposed this bug to a greater extent. That bug is addressed in the next patch in this series. This bug is also responsible for the bug in https://bugzilla.kernel.org/show_bug.cgi?id=42815. and this bug is also part of the problems discussed at https://bugs.archlinux.org/task/27996#comment89950.
