rtlwifi: pci: Fix oops on driver unload

2013-12-17T18:58:25+00:00

On Fedora systems, unloading rtl8192ce causes an oops. This patch fixes the
problem reported at https://bugzilla.redhat.com/show_bug.cgi?id=852761.

rtlwifi: rtl8192cu: Fix more pointer arithmetic errors

2013-11-15T19:29:33+00:00

This driver uses a number of macros to get and set various fields in the
RX and TX descriptors. To work correctly, a u8 pointer to the descriptor
must be used; however, in some cases a descriptor structure pointer is used
instead. In addition, a duplicated statement is removed.

rtlwifi: rtl8192de: Fix incorrect signal strength for unassociated AP

2013-11-11T19:42:44+00:00

The routine that processes received frames was returning the RSSI value for the
signal strength; however, that value is available only for associated APs. As
a result, the strength was the absurd value of 10 dBm. As a result, scans
return incorrect values for the strength, which causes unwanted attempts to roam.

rtlwifi: Fix endian error in extracting packet type

2013-11-11T19:42:43+00:00

All of the rtlwifi drivers have an error in the routine that tests if
the data is "special". If it is, the subsequant transmission will be
at the lowest rate to enhance reliability. The 16-bit quantity is
big-endian, but was being extracted in native CPU mode. One of the
effects of this bug is to inhibit association under some conditions
as the TX rate is too high.

Based on suggestions by Joe Perches, the entire routine is rewritten.

One of the local headers contained duplicates of some of the ETH_P_XXX
definitions. These are deleted.

rtlwifi: fix null dereference on efuse_word on kmalloc fail returns NULL

2013-11-11T19:38:58+00:00

kmalloc on efuse_word can return null, leading to free'ing of
elements in efuse_word on the error exit path even though it has not
been allocated.  Instead, don't free the elements of efuse_word if
kmalloc failed.

Also, kmalloc of any of the arrays in efuse_word[] can also fail,
leading to undefined contents in the remaining elements leading to
problems when free'ing these elements later on.  So kzalloc efuse_word
to ensure the kfree on the remaining elements won't cause breakage.

rtlwifi: rtl8192se: Fix wrong assignment

2013-11-11T19:38:55+00:00

There is a typo in the struct member name on assignment when checking
rtlphy->current_chan_bw == HT_CHANNEL_WIDTH_20_40, the check uses pwrgroup_ht40
for bound limit and uses pwrgroup_ht20 when assigning instead.

rtlwifi: rtl8192cu: Fix error in pointer arithmetic

2013-10-10T18:05:41+00:00

An error in calculating the offset in an skb causes the driver to read
essential device info from the wrong locations. The main effect is that
automatic gain calculations are nonsense.
