From 354210f8046cc801d6001f10c5c32967932b09a2 Mon Sep 17 00:00:00 2001 From: Bob Copeland Date: Sat, 19 Dec 2015 09:59:37 -0500 Subject: Revert "mac80211_hwsim: support any address in userspace" This reverts commit cd37a90b2a417e5882414e19954eeed174aa4d29. Different userspace programs interpreted HWSIM_ATTR_ADDR_TRANSMITTER and HWSIM_ATTR_ADDR_RECEIVER differently: some expected it to be an unchanging hardware address that is tied to the radio despite which address is configured on the interface, while others expected to be a copy of the address in the frame (the configured address). The intent of the original authors is unclear. The latter interpretation doesn't really work properly with multiple vifs and broadcast frames. Also, as the TA is already in the frame, userspace programs can actually support configured addresses in the former interpretation by mapping between them and the supplied HWSIM_ATTR_ADDR_TRANSMITTER. So, in the interest of API stability, revert to the previous mode of operation and going forward use the former interpretation.

The problems started with kernel 4.2, which is the first version that had commit d10101a60372 ("rtlwifi: rtl8821ae: Fix problem with regulatory information"). With this patch, the driver went from setting a default channel plan to using the value derived from EEPROM. Bug reports at https://bugzilla.kernel.org/show_bug.cgi?id=111031 and https://bugzilla.redhat.com/show_bug.cgi?id=1279653 are examples of this problem. The problem was solved once I learned that the internal country code was resulting in a regulatory set with only 2.4 GHz channels. With the RTL8821AE chips available to me, the country code was such that both 2.4 and 5 GHz channels are allowed. The fix is to allow both bands even when the EEPROM is incorrectly encoded.

In tx response, which is used mostly for a single frame case 2. In BA notification When tx aggregation fails with the initial rate, FW will send to the driver BA notification and will try to transmit with the next rate, but this time without tx power reduction. Thus, in case of a failure with the initial rate, driver will get two BA notifications, the first one with reduced tx power as in the LQ command and the second one with 0 power reduction. This patch adapts the TPC statistics according to the description above: 1. Use BA notifications instead of Tx response 2. For TPC only, drop the optimization which considers empty BA as one MPDU. The reason is that with TPC we want to recover very quickly from a bad power reduction and, therefore we'd like the success ratio to get an immediate hit when failing to get a BA, so we'd switch back to a lower or zero power reduction Signed-off-by: Gregory Greenman Signed-off-by: Emmanuel Grumbach --- drivers/net/wireless/intel/iwlwifi/mvm/fw-api-tx.h | 6 +- drivers/net/wireless/intel/iwlwifi/mvm/rs.c | 74 ++++++++++++++-------- drivers/net/wireless/intel/iwlwifi/mvm/tx.c | 5 +- 3 files changed, 56 insertions(+), 29 deletions(-) (limited to 'drivers/net/wireless') diff --git a/drivers/net/wireless/intel/iwlwifi/mvm/fw-api-tx.h b/drivers/net/wireless/intel/iwlwifi/mvm/fw-api-tx.h index 0036d18334af..ba3f0bbddde8 100644 --- a/drivers/net/wireless/intel/iwlwifi/mvm/fw-api-tx.h +++ b/drivers/net/wireless/intel/iwlwifi/mvm/fw-api-tx.h @@ -510,6 +510,9 @@ struct iwl_mvm_tx_resp { * @scd_ssn: the index of the last contiguously sent packet * @txed: number of Txed frames in this batch * @txed_2_done: number of Acked frames in this batch + * @reduced_txp: power reduced according to TPC.

We also rely on the ISR to wake up the thread when the DMA has finished copying a chunk. During this flow, we enable the RF-Kill interrupt. The problem is that the RF-Kill interrupt handler can take the mutex and bring the device down. This means that if we load the firmware while the RF-Kill switch is enabled (which will happen when we load the INIT firmware to read the device's capabilities and register to mac80211), we may get an RF-Kill interrupt immediately and the ISR will be waiting for the mutex held by the thread that is currently loading the firmware. At this stage, the ISR won't be able to service the DMA's interrupt needed to wake up the thread that load the firmware. We are in a deadlock situation which ends when the thread that loads the firmware fails on timeout and releases the mutex. To fix this, take the mutex later in the flow, disable the interrupts and synchronize_irq() to give a chance to the RF-Kill interrupt to run and complete. After that, mask all the interrupts besides the DMA interrupt and proceed with firmware load. Make sure to check that there was no RF-Kill interrupt when the interrupts were disabled.
