2011-09-28libceph: fix pg_temp mapping calculationSage Weil
We need to apply the modulo pg_num calculation before looking up a pgid in the pg_temp mapping rbtree. This fixes pg_temp mappings, and fixes (some) misdirected requests that result in messages like [WRN] client4104 10.0.1.219:0/275025290 misdirected client4104.1:129 0.1 to osd0 not [1,0] in e11/11 on the server and stall make the client block without getting a reply (at least until the pg_temp mapping goes way, but that can take a long long time). Reorder calc_pg_raw() a bit to make more sense. Signed-off-by: Sage Weil <sage@newdream.net>

2011-09-28ath6kl: silence "invalid rate" warningKalle Valo
For some reason firmware is sending invalid rates when we try to query current bitrate from ath6kl_get_station() and a warning is issued: [ 3810.415720] ath6kl: invalid rate: 1935633515 [ 3811.105493] ath6kl: invalid rate: 1935633515 [ 3811.556063] ath6kl: invalid rate: 1935633515 As the warning happens way too often, convert the warning to a debug message once we have a proper fix. But to make it easy to follow how often the problem appears, add a debugfs to print various statistics about workarounds and make this issue the first WAR.

Fix that by checking the microcode before creating the platform device rather than at probe time. Also avoid calling TO_PHYS_ID(cpu) twice in the same function, it's expensive.

2011-09-28block: Free queue resources at blk_release_queue()Hannes Reinecke
A kernel crash is observed when a mounted ext3/ext4 filesystem is physically removed. The problem is that blk_cleanup_queue() frees up some resources eg by calling elevator_exit(), which are not checked for in normal operation. So we should rather move these calls to the destructor function blk_release_queue() as at that point all remaining references are gone. However, in doing so we have to ensure that any externally supplied queue_lock is disconnected as the driver might free up the lock after the call of blk_cleanup_queue(), Signed-off-by: Hannes Reinecke <hare@suse.de> Signed-off-by: Jens Axboe <axboe@kernel.dk>

2011-09-27Bluetooth: use recommended LE connection parametersAnderson Lizardo
The new connection parameters now match the recommended values for Proximity and Health Thermometer profiles. The previous values were ramdomly chosen, and are either too low or too high for most cases. New values: Scan Interval: 60 ms Scan Window: 30 ms Minimum Connection Interval: 50 ms Maximum Connection Interval: 70 ms Supervision Timeout: 420 ms See "Table 5.2: Recommended Scan Interval and Scan Window Values" and "Table 5.3: Recommended Connection Interval Values" for both profiles for details. Note that the "fast connection" parameters were chosen, because we do not support yet dynamically changing these parameters from initiator side. Additionally, the Proximity profile recommends (section "4.4 Alert on Link Loss"): "It is recommended that the Link Supervision Timeout (LSTO) is set to 6x the connection interval." Minimum_CE_Length and Maximum_CE_Length were also changed from 0x0001 to 0x0000 because they are informational and optional, and old value was not reflecting reality.

ERTM reassembly will be more efficient when skbs are linked together rather than copying every incoming data byte.

2011-09-27Bluetooth: Allow ACL packets over USB in HCI_RAW modePeter Hurley
Removed tests which prevent transmission of ACL packets when the device is in HCI_RAW mode. These tests verified that there are ACL or LE links currently tracked by the HCI connection manager. However, a HCI_RAW mode device does not use the connection manager. In these circumstances, the connection counts will be zero, and thus, transmitted ACL packets dropped. The acl_num test is actually a vestige of a previous bulk URB scheme that is no longer used by this driver (bulk URBs were not started until at least one ACL connection was created). This was incompatible with some endpoint implementations and was dropped - see commit 43c2e57f94. The utility of these tests is marginal - currently, the hci tx scheduler cannot send an ACL or LE packet for an untracked connection (except if the device is in HCI_RAW mode). Lastly, no other transport layer driver enforces these same tests.

wrqu->encoding.length comes from the network administrator. It's size u16. We want to limit "tocopy" to the smallest value of either "len_keys", "wrqu->encoding.length" or 100. But because .length gets cast from u16 to u8 we might use a random, smaller value than the was desired. It's probably not very serious, but we may as well fix it.

Whenever the scan request or tx_mgmt is requesting not to use CCK rate for managemet frames through NL80211_ATTR_TX_NO_CCK_RATE attribute, then mac80211 should select appropriate least non-CCK rate.

Add a new nl80211 attribute to specify whether to send the management frames in CCK rate or not. As of now the wpa_supplicant is disabling CCK rate at P2P init itself. So this patch helps to send P2P probe request/probe response/action frames being sent at non CCK rate in 2GHz without disabling 11b rates. This attribute is used with NL80211_CMD_TRIGGER_SCAN and NL80211_CMD_FRAME commands to disable CCK rate for management frame transmission.

2011-09-27iwlagn: fix scan complete processingJohannes Berg
When we cancel a scan, the completion runs only from the workqueue. This can cause the remain-on-channel scan to fail when another one was just canceled, because we're still aborting it. To fix this, run the completion inline with the lock still held before returning from iwl_scan_cancel_timeout(). Also, to avoid the scan complete work from completing a new scan prematurely, add a new STATUS_SCAN_COMPLETE bit.

2011-09-27iwlagn: fix dangling scan requestJohannes Berg
If iwl_scan_initiate() fails for any reason, priv->scan_request and priv->scan_vif are left dangling. This can lead to a crash later when iwl_bg_scan_completed() tries to run a pending scan request. In practice, this seems to be very rare due to the STATUS_SCANNING check earlier. That check, however, is wrong -- it should allow a scan to be queued when a reset/roc scan is going on. When a normal scan is already going on, a new one can't be issued by mac80211, so that code can be removed completely. I introduced this bug when adding off-channel support in commit 266af4c745952e9bebf687dd68af58df553cb59d.
