2010-04-16WAN: flush tx_queue in hdlc_ppp to prevent panic on rmmod hw_driver.Krzysztof Halasa
tx_queue is used as a temporary queue when not allowed to queue skb directly to the hw device driver (which may sleep). Most paths flush it before returning, but ppp_start() currently cannot. Make sure we don't leave skbs pointing to a non-existent device. Thanks to Michael Barkowski for reporting this problem. Signed-off-by: Krzysztof Hałasa <khc@pm.waw.pl> Signed-off-by: David S.

2010-04-16iwlwifi: fix scan racesJohannes Berg
When an internal scan is started, nothing protects the is_internal_short_scan variable which can cause crashes, cf. https://bugzilla.kernel.org/show_bug.cgi?id=15667. Fix this by making the short scan request use the mutex for locking, which requires making the request go to a work struct so that it can sleep.

2010-04-14tun: orphan an skb on txMichael S. Tsirkin
The following situation was observed in the field: tap1 sends packets, tap2 does not consume them, as a result tap1 can not be closed. This happens because tun/tap devices can hang on to skbs undefinitely. As noted by Herbert, possible solutions include a timeout followed by a copy/change of ownership of the skb, or always copying/changing ownership if we're going into a hostile device. This patch implements the second approach. Note: one issue still remaining is that since skbs keep reference to tun socket and tun socket has a reference to tun device, we won't flush backlog, instead simply waiting for all skbs to get transmitted. At least this is not user-triggerable, and this was not reported in practice, my assumption is other devices besides tap complete an skb within finite time after it has been queued. A possible solution for the second issue would not to have socket reference the device, instead, implement dev->destructor for tun, and wait for all skbs to complete there, but this needs some thought, probably too risky for 2.6.34.

2010-04-09iwlwifi: work around bogus active chains detectionJohannes Berg
The current algorithm will sometimes "detect" that more chains are enabled than are really present in the device because, for unknown reasons, the ucode sends up all-zeroes signal values. The simplest way of solving this is to restrict the active chains mask to the chains we know are really present on the device. This fixes a bug with some devices where, since sometimes more chains are enabled than really present, the system would hang.

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.

2010-04-02iwlwifi: avoid Tx queue memory allocation in interface downZhu Yi
We used to free all the Tx queues memory when interface is brought down and reallocate them again in interface up. This requires order-4 allocation for txq->cmd[]. In situations like s2ram, this usually leads to allocation failure in the memory subsystem. The patch fixed this problem by allocating the Tx queues memory only at the first time. Later iwl_down/iwl_up only initialize but don't free and reallocate them. The memory is freed at the device removal time. BTW, we have already done this for the Rx queue.

2010-04-02iwlwifi: use consistent table for tx data collectShanyu Zhao
When collecting tx data for non-aggregation packets in rate scaling, if the tx data matches "other table", it still uses current table to update the stats and calculate average throughput in function rs_collect_tx_data(). This can mess up the rate scaling data structure and cause a kernel panic in a BUG_ON statement in rs_rate_scale_perform(). To fix this bug, we pass table pointer instead of window pointer (pointed to by table pointer) to function rs_collect_tx_data() so that the table being used is consistent.

2010-03-30net/wireless/libertas: do not call wiphy_unregister() w/o wiphy_register()Daniel Mack
The libertas driver calls wiphy_unregister() without a prior wiphy_register() when a devices fails initialization. Fix this by introducing a private flag.

2010-03-30iwlwifi: range checking issueDan Carpenter
IWL_RATE_COUNT is 13 and IWL_RATE_COUNT_LEGACY is 12. IWL_RATE_COUNT_LEGACY is the right one here because iwl3945_rates doesn't support 60M and also that's how "rates" is defined in iwlcore_init_geos() from drivers/net/wireless/iwlwifi/iwl-core.c. rates = kzalloc((sizeof(struct ieee80211_rate) * IWL_RATE_COUNT_LEGACY), GFP_KERNEL); Signed-off-by: Dan Carpenter <error27@gmail.com> Cc: stable@kernel.org Acked-by: Zhu Yi <yi.zhu@intel.com> Signed-off-by: John W.

2010-03-30setup correct int pipe type in ar9170_usb_exec_cmdValentin Longchamp
An int urb is constructed but we fill it in with a bulk pipe type. Commit f661c6f8c67bd55e93348f160d590ff9edf08904 implemented a pipe type check when CONFIG_USB_DEBUG is enabled. The check failed for all the ar9170 usb transfers and the driver could not configure the wifi dongle. This went unnoticed until now because most people don't have CONFIG_USB_DEBUG enabled.

Recent bug reports have shown that rt2500usb also suffers from the powersave problems that the PCI rt2x00 drivers suffer from. So disable powersaving by default for rt2500usb as well.

2010-03-30iwlwifi: clear unattended interrupts in taskletShanyu Zhao
Previously in interrupt handling tasklet, iwlwifi driver only clear/ack those interrupts that are enabled by the driver through inta_mask. If the hardware generates unattended interrupts, driver will not ack them, defeating the interrupt coalescing feature. This results in high number of interrupts per second and high CPU utilization. This patch addresses this issue by acking those unattended interrupts in the tasklet. Local test showed an order of magnitude improvement in terms of the number of interrupts without sacrificing networking throughput. This is a workaround for hardware issue.
