2014-05-13rtlwifi: rtl8192se: Fix regression due to commit 1bf4bbbLarry Finger1-0/+6
commit 5f9186990ec4579ee5b7a99b3254c29eda479f36 upstream. Beginning with kernel 3.13, this driver fails on some systems. The problem was bisected to: Commit 1bf4bbb4024dcdab5e57634dd8ae1072d42a53ac Author: Felix Fietkau <nbd@openwrt.org> Title: mac80211: send control port protocol frames to the VO queue There is noting wrong with the above commit. The regression occurs because V0 queue on RTL8192SE cards uses priority 6, not the usual 7. The fix is to modify the rtl8192se routine that sets the correct transmit queue.

[Q]-0 (stream=0, delta=15903, new_hw_ptr=293408, old_hw_ptr=277505) The exact code flow that causes that is: 1. wpa_supplicant send a start_scan request to the nl80211 driver 2. mac80211 module call rtl_op_config with IEEE80211_CONF_CHANGE_IDLE 3. rtl_ips_nic_on is called which disable local irqs 4. rtl92c_phy_set_rf_power_state() is called 5. rtl_ps_enable_nic() is called and hw_init()is executed and then the interrupts on the device are enabled A good solution could be to refactor the code to avoid calling rtl92ce_hw_init() with the irqs disabled but a quick and dirty solution that has proven to work is to reenable the irqs during the function rtl92ce_hw_init(). I think that it is safe doing so since the device interrupt will only be enabled after the init function succeed.

commit 2e8c5e56b307271c2dab6f8bfd1d8a3822ca2390 upstream. rtl_ps_enable_nic() is called from loops that will loop until this function returns true or a maximum number of retries is performed. hw_init() returns non-zero on error. In that situation return false to restore the original design intent to retry hw init when it fails.

2013-12-04rtlwifi: Fix endian error in extracting packet typeMark Cave-Ayland2-57/+42
commit 0c5d63f0ab6728f05ddefa25aff55e31297f95e6 upstream. 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.

commit 9473ca6e920a3b9ca902753ce52833657f9221cc upstream. 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.

2013-10-14rtlwifi: Align private space in rtl_priv structLarry Finger1-1/+1
commit 60ce314d1750fef843e9db70050e09e49f838b69 upstream. The private array at the end of the rtl_priv struct is not aligned. On ARM architecture, this causes an alignment trap and is fixed by aligning that array with __align(sizeof(void *)). That should properly align that space according to the requirements of all architectures.

2013-08-04rtlwifi: Initialize power-setting callback for USB devicesLarry Finger4-13/+15
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.

2013-07-22rtlwifi: rtl8192cu: Fix duplicate if testLarry Finger1-1/+1
commit 10d0b9030a3f86e1e26c710c7580524d7787d688 upstream. A typo causes routine rtl92cu_phy_rf6052_set_cck_txpower() to test the same condition twice. The problem was found using cppcheck-1.49, and the proper fix was verified against the pre-mac80211 version of the code. This patch was originally included as commit 1288aa4, but was accidentally reverted in a later patch.
