From 8ab5415d6c701a59dd6fc2bc93cf476ecc03ada5 Mon Sep 17 00:00:00 2001 From: Jouni Malinen Date: Wed, 9 May 2012 22:14:51 +0300 Subject: ath6kl: Use correct max-scan-SSIDs limit The currently used firmware images support 16 SSIDs in the scan request (indexes 0..15), so update the host driver to use the same limit to allow some more SSIDs to be scanned per request. In addition, change the max-index to max-SSIDs to make it easier to understand the implementation and fix couple of off-by-one checks that could limit the maximum number of entries too strictly.

Pass the right reason code to cfg80211 on the first disconnect instead. This fixes at least one bug where a p2p client would stop trying to connect after receiving a stale RSN deauth which was reported to cfg80211 as GO leaving BSS.

In the code for del_beacon in cfg80211.c,set_ht_cap is being called first for 2.4 GHZ and then for 5 GHZ. When called for the first time for 2.4 GHZ the enable flag will be set to true and so when called for the second time for 5 GHZ it just returns after checking the flag. Also using this one can have different HT capabilities per band (for example one may decide not to use 20/40 in 2.4 GHZ but use it in 5 GHZ).

For example, this cast: int y; int *p = (int *)&y; I used the coccinelle script below to find and remove these unnecessary casts. I manually removed the conversions this script produces of casts with __force, __iomem and __user. @@ type T; T *p; @@ - (T *)p + p Neatened the mwifiex_deauthenticate_infra function which was doing odd things with array pointers and not using is_zero_ether_addr.

This has been root caused to the delay in releasing pending a-mpdu subframes in reorder buffer. Right now the timeout value is 400ms, there is also a race condition where timeout handler can be delayed to run at an extra timeout interval. This patch reduces the timout interval to reasonable 100ms and makes sure releasing pending frames are not skipped in the timeout handler by removing the flag (rxtid->progress) which can delay the timeout logic.

Ideally this WAR is needed to recover from some rare beacon stuck during stress testing. Before the STA is associated/IBSS had started beaconing, PLL4(0x1618c) always seem to have zero even though we had configured PLL3(0x16188) to query about PLL's locking status. When we keep on polling infinitely PLL4's 8th bit(ie check for PLL locking measurements is done), machine hangs due to softlockup. fixes https://bugzilla.redhat.com/show_bug.cgi?id=811142 Reported-by: Rolf Offermanns Cc: stable@vger.kernel.org Tested-by: Mohammed Shafi Shajakhan Signed-off-by: Mohammed Shafi Shajakhan Signed-off-by: John W.

The beacon RSSI is only valid in station mode, and the main reason to check it in ath9k_hw_set_ofdm_nil is to make sure that OFDM weak signal detection stays enabled if the RSSI is low, even when the OFDM noise immunity entry is supposed to disable it. The above commit removed the mode checks and changed the code so that OFDM weak signal detection would only be changed if the rssi is high, which is wrong for everything but client mode. This patch restores the old behavior in a simplified form. Signed-off-by: Felix Fietkau Signed-off-by: John W.

So far, ampdu factor/density are only calculated when the station is initially added. This patch changes this to update ampdu factor/density settings when starting a blockack session. Using this patch, we had performance boosts from 60 to 150 MBit/s between two 2x2 Atheros devices in 5 GHz HT IBSS mode.

Due to this, mac80211 had even rejected the hardware registration. By making all the code and data for WoWLAN depend on CONFIG_PM we can promote this runtime error to a compile-time error. Add #ifdef around all WoWLAN code to remove it in systems that don't need it as they never suspend.

Unfortunately this is also being set for AP mode, since it's mixed with code that is only supposed to change the default settings after a reset. In AP mode this has the side effect of having ANI run, but being unable to change its runtime noise immunity level, making it effectively useless. Fix this by getting rid of ani->update_ani and passing a parameter to ath9k_hw_set_ofdm_nil and ath9k_hw_set_cck_nil instead.

IEEE80211_TX_MAX_RATES IEEE80211_TX_MAX_RATES can be reduced from 5 to 4 as there is no current hardware supporting a rate chain with 5 multi rate stages (mrr), so 4 mrr stages are sufficient. The memory that is freed within the ieee80211_tx_info struct will be used in the upcoming Transmission Power Control (TPC) implementation.
