2010-04-08ath5k: add bounds check to pdadc tableBob Copeland
We check the bounds on pdadc once when correcting for negative curves but not when we later copy values from from the pdadc_tmp array, leading to a potential overrun. Although we shouldn't hit this case in practice, let's be consistent.

2010-04-08ath5k: fix race condition in tx desc processingBob Copeland
As pointed out by Benoit Papillault, there is a potential race condition between the host and the hardware in reading the next link in the transmit descriptor list: cpu0 hw tx for buf completed raise tx_ok interrupt process buf buf->ds_link = 0 read buf->ds_link This change checks txdp before processing a descriptor (if there are any subsequent descriptors) to see if hardware moved on. We'll then process this descriptor on the next tasklet. Signed-off-by: Bob Copeland <me@bobcopeland.com> Acked-by: Bruno Randolf <br1@einfach.org> Signed-off-by: John W.

2010-04-08ath5k: clean up queue manipulationBob Copeland
Review spotted a couple of strange invocations to ieee80211_wake_queues that could potentially cause problems: - queues are awakened in the calibration tasklet before phy calibration, and then again after calibration - queues are awakened inside reset when we're trying to drain the ath5k transmit queues, and again after reset is completed (in callers to ath5k_reset_wake). In both cases the first wake is unnecessary, so remove it. Signed-off-by: Bob Copeland <me@bobcopeland.com> Acked-by: Bruno Randolf <br1@einfach.org> Signed-off-by: John W.

2010-04-08ath5k: correct channel setting for 2.5 mhz spacingBob Copeland
These channels aren't selectable anyway, but our calculations for 2.5 mhz frequencies are incorrect. The value is supposed to be: (frequency - reference) * (10/25) i.e., divide by 2.5, but we were instead doing: (10 * frequency - reference) / 25. Additionally, the check for (frequency % 5 == 2) had an extra subtraction that wasn't in madwifi HAL.

2010-04-08rt2x00: use rt2800_config_channel_rt3x for rt2872Helmut Schaa
rt2872 needs the same rf register setup as rt3070 and rt3090, hence use rt2800_config_channel_rt3x instead of rt2800_config_channel_rt2x. This change allows me to actually switch channels and hence scan all configured channels on the RT305x SoC platform (which uses a rt2872) here.

2010-04-08ath9k: simplify AR9220 fixup code for AR_AN_TOP2 registerPavel Roskin
Don't modify ah->iniModes, it's supposed to be constant. Instead, apply the fixup when the data is written to the registers. Change ath9k_hw_init_eeprom_fix() to only determine whether the fixup is needed. This allows similteneous support for AR9220 cards that need AR_AN_TOP2 fixup (such as Ubiquiti SR71-12) and those that don't need it (D-Link DWA-552 rev A2).

2010-04-073c503: Fix IRQ probingBen Hutchings
The driver attempts to select an IRQ for the NIC automatically by testing which of the supported IRQs are available and then probing each available IRQ with probe_irq_{on,off}(). There are obvious race conditions here, besides which: 1. The test for availability is done by passing a NULL handler, which now always returns -EINVAL, thus the device cannot be opened: <http://bugs.debian.org/566522> 2. probe_irq_off() will report only the first ISA IRQ handled, potentially leading to a false negative. There was another bug that meant it ignored all error codes from request_irq() except -EBUSY, so it would 'succeed' despite this (possibly causing conflicts with other ISA devices). This was fixed by ab08999d6029bb2c79c16be5405d63d2bedbdfea 'WARNING: some request_irq() failures ignored in el2_open()', which exposed bug 1. This patch: 1. Replaces the use of probe_irq_{on,off}() with a real interrupt handler 2. Adds a delay before checking the interrupt-seen flag 3. Disables interrupts on all failure paths 4. Distinguishes error codes from the second request_irq() call, consistently with the first Compile-tested only. Signed-off-by: Ben Hutchings <ben@decadent.org.uk> Signed-off-by: David S.

2010-04-07r6040: fix r6040_multicast_listFlorian Fainelli
As reported in <https://bugzilla.kernel.org/show_bug.cgi?id=15355>, r6040_ multicast_list currently crashes. This is due a wrong maximum of multicast entries. This patch fixes the following issues with multicast: - number of maximum entries if off-by-one (4 instead of 3) - the writing of the hash table index is not necessary and leads to invalid values being written into the MCR1 register, so the MAC is simply put in a non coherent state - when we exceed the maximum number of mutlticast address, writing the broadcast address should be done in registers MID_1{L,M,H} instead of MID_O{L,M,H}, otherwise we would loose the adapter's MAC address Signed-off-by: Florian Fainelli <florian@openwrt.org> Signed-off-by: David S.

2010-04-07ath5k: Adaptive Noise Immunity (ANI) ImplementationBruno Randolf
This is an Adaptive Noise Imunity (ANI) implementation for ath5k. I have looked at both ath9k and HAL sources (they are nearly the same), and even though i have implemented some things differently, the basic algorithm is practically the same, for now. I hope that this can serve as a clean start to improve the algorithm later. This also adds a possibility to manually control ANI settings, right now only thru a debugfs file: * set lowest sensitivity (=highest noise immunity): echo sens-low > /sys/kernel/debug/ath5k/phy0/ani * set highest sensitivity (=lowest noise immunity): echo sens-high > /sys/kernel/debug/ath5k/phy0/ani * automatically control immunity (default): echo ani-on > /sys/kernel/debug/ath5k/phy0/ani * to see the parameters in use and watch them change: cat /sys/kernel/debug/ath5k/phy0/ani Manually setting sensitivity will turn the automatic control off. You can also control each of the five immunity parameters (noise immunity, spur immunity, firstep, ofdm weak signal detection, cck weak signal detection) manually thru the debugfs file. This is tested on AR5414 and nearly doubles the thruput in a noisy 2GHz band. Signed-off-by: Bruno Randolf <br1@einfach.org> Signed-off-by: John W. Linville <linville@tuxdriver.com>
