2010-08-08e100/e1000*/igb*/ixgb*: Add missing read memory barrierJeff Kirsher
Based on patches from Sonny Rao and Milton Miller... Combined the patches to fix up clean_tx_irq and clean_rx_irq. The PowerPC architecture does not require loads to independent bytes to be ordered without adding an explicit barrier. In ixgbe_clean_rx_irq we load the status bit then load the packet data. With packet split disabled if these loads go out of order we get a stale packet, but we will notice the bad sequence numbers and drop it. The problem occurs with packet split enabled where the TCP/IP header and data are in different descriptors. If the reads go out of order we may have data that doesn't match the TCP/IP header. Since we use hardware checksumming this bad data is never verified and it makes it all the way to the application. This bug was found during stress testing and adding this barrier has been shown to fix it. The bug can manifest as a data integrity issue (bad payload data) or as a BUG in skb_pull(). This was a nasty bug to hunt down, if people agree with the fix I think it's a candidate for stable. Previously Submitted to e1000-devel only for ixgbe http://marc.info/?l=e1000-devel&m=126593062701537&w=3 We've now seen this problem hit with other device drivers (e1000e mostly) So I'm resubmitting with fixes for other Intel Device Drivers with similar issues.

2010-08-08ixgbe: fix build error with FCOE_CONFIG without DCB_CONFIGJohn Fastabend
Building ixgbe without DCB_CONFIG and FCOE_CONFIG will cause a build error. This resolves the build error by wrapping the fcoe.up in CONFIG_IXGBE_DCB ifdefs. Also frames were being priority VLAN tagged even without DCB enabled. This fixes this so that 8021Q priority tags are only added with DCB actually enabled.

2010-08-05libertas: scan before assocation if no BSSID was givenDan Williams
Fix this leftover TODO from the cfg80211 conversion by doing a scan if cfg80211 didn't pass in the BSSID for us. Since the scan code uses so much of the cfg80211_scan_request structure to build up the firmware command, we just fake one when the scan request is triggered internally. But we need to make sure that internal 'fake' cfg82011 scan request does not get back to cfg82011 via cfg80211_scan_done(). Signed-off-by: Dan Williams <dcbw@redhat.com> Signed-off-by: John W.

I noticed a possible issue in the paused flag management of the ath_atx_tid data structure. In particular, in a noisy environment and under heavy load, I observed that the AGGR session establishment could fail several times consecutively causing values of the paused flag greater than one for this TID (ath_tx_pause_tid is called more than once from ath_tx_aggr_start). Considering that the session for this TID can not be established also after the mac80211 stack calls the ieee80211_agg_tx_operational() since the ath_tx_aggr_resume() lowers the paused flag only by one. This patch also replaces some BUG_ON calls with WARN_ON, as even if these unlikely conditions happen, it's not fatal enough to justify a BUG_ON.

2010-08-04ath9k_hw: Fix regulatory CTL index usage for AR9003Luis R. Rodriguez
AR9003 was not relying on the CTL indexes from the EEPROM for capping the max output power. The CTL indexes from the EEPROM provide calibrated limits for output power for each tested and supported frequency. Without this the device operates at a power level which only conforms to the transmit spectrum mask as specified by IEEE Annex I.2.3. The regulatory limit by CRDA is always used but does not provide calibrated values for optimal performance, specially on band edges. Using the calibrated data from the EEPROM ensures the device operates at optimal output power while still ensuring proper regulatory compliance. The device uses the minimum of these tree values, the value from CRDA, the calibrated value from CTL indexex, and the value to conform to the IEEE transmit spectrum mask. Signed-off-by: Luis R.

2010-08-04iwlwifi: fix compile warningJohannes Berg
When iwlwifi is compiled w/o debug, we get this warning: iwl-agn.c: In function ‘iwlagn_load_firmware’: iwl-agn.c:2014: warning: passing argument 3 of ‘iwl_print_hex_dump’ discards qualifiers from pointer target type iwl-debug.h:73: note: expected ‘void *’ but argument is of type ‘const u8 *’ because the const qualifier is missing in the inline stub. Fix this. Signed-off-by: Johannes Berg <johannes.berg@intel.com> Signed-off-by: Wey-Yi Guy <wey-yi.w.guy@intel.com> Signed-off-by: John W. Linville <linville@tuxdriver.com>
2010-08-04ath9k_hw: fix a noise floor calibration related race conditionFelix Fietkau
On AR5008-AR9002, other forms of calibration must not be started while the noise floor calibration is running, as this can create invalid readings which were sometimes not even recoverable by any further calibration attempts. This patch also ensures that the result of noise floor measurements are processed faster and also allows the result of the initial calibration on reset to make it into the NF history buffer Signed-off-by: Felix Fietkau <nbd@openwrt.org> Signed-off-by: John W. Linville <linville@tuxdriver.com>
2010-08-04ath9k_hw: clean up per-channel calibration dataFelix Fietkau
The noise floor history buffer is currently not kept per channel, which can lead to problems when changing channels from a clean channel to a noisy one. Also when switching from HT20 to HT40, the noise floor history buffer is full of measurements, but none of them contain data for the extension channel, which it needs quite a bit of time to recover from. This patch puts all the per-channel calibration data into a single data structure, and gives the the driver control over whether that is used per-channel or even not used for some channels. For ath9k_htc, I decided to keep this per-channel in order to avoid creating regressions. For ath9k, the data is kept only for the operating channel, which saves some space. ath9k_hw takes care of wiping old data when the operating channel or its channel flags change.

2010-08-04ath9k: prevent calibration during off-channel activityFelix Fietkau
Previously the software scan callback was used to indicate to the hardware, when it was safe to calibrate. This didn't really work properly, because it depends on a specific order of software scan callbacks vs. channel changes. Also, software scans are not the only thing that triggers off-channel activity, so it's better to use the newly added indication from mac80211 for this and not use the software scan callback for anything calibration related. This fixes at least some of the invalid noise floor readings that I've seen in AP mode on AR9160 Signed-off-by: Felix Fietkau <nbd@openwrt.org> Signed-off-by: John W.

2010-08-04ath9k_hw: fix analog shift register writes on AR9003Felix Fietkau
Writes to the analog shift registers, which are issues by the initval programming function, require a 100 usec delay (similar to AR9002, but in a different register range).

2010-08-04ath9k: fix a crash in the PA predistortion apply functionFelix Fietkau
When updating the PAPRD table in hardware, PAPRD itself needs to be disabled first, otherwise the hardware can throw a data bus error, which upsets at least some platforms.

2010-08-04ath9k_hw: fix periodic noise floor calibration on AR9003Felix Fietkau
The periodic noise floor calibration is broken on this chip family, because it keeps triggering a software-filtered noise floor calibration, but never reads the result before uploading the history buffer value to the hardware. Fix this with a call to ath9k_hw_getnf(), just like on AR9002. Signed-off-by: Felix Fietkau <nbd@openwrt.org> Acked-by: Luis R. Rodriguez <lrodriguez@atheros.com> Signed-off-by: John W.

2010-08-04ath9k_hw: clean up and fix initial noise floor calibrationFelix Fietkau
On AR9003 the initial noise floor calibration is currently triggered at the end of the reset without allowing the hardware to update the baseband settings. This could potentially make scans in noisy environments a bit more unreliable, so use the same calibration sequence that is used on AR9002.

2010-08-04iwlwifi: fix possible recursive locking deadlockJohannes Berg
commit f84b29ec0a1ab767679d3f2428877b65f94bc3ff Author: Johannes Berg <johannes.berg@intel.com> Date: Tue May 18 02:29:13 2010 -0700 iwlwifi: queue user-initiated scan when doing internal scan introduced a potential deadlock because it calls ieee80211_scan_completed() with the priv->mutex held, but mac80211 may call back into iwlwifi which would lead to recursive locking.
