* tcp: Stalling connections: Move timeout calculation routineDamian Lukowski2009-12-082-28/+29

* tcp: Stalling connections: Fix timeout calculation routineDamian Lukowski2009-12-081-2/+8
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This patch fixes a problem in the TCP connection timeout calculation. Currently, timeout decisions are made on the basis of the current tcp_time_stamp and retrans_stamp, which is usually set at the first retransmission. However, if the retransmission fails in tcp_retransmit_skb(), retrans_stamp is not updated and remains zero. This leads to wrong decisions in retransmits_timed_out() if tcp_time_stamp is larger than the specified timeout, which is very likely. In this case, the TCP connection dies after the first attempted (and unsuccessful) retransmission. With this patch, tcp_skb_cb->when is used instead, when retrans_stamp is not available. This bug has been introduced together with retransmits_timed_out() in 2.6.32, as the number of retransmissions has been used for timeout decisions before. The corresponding commit was 6fa12c85031485dff38ce550c24f10da23b0adaa (Revert Backoff [v3]: Calculate TCP's connection close threshold as a time value.).

* net/mpc5200: Fix locking on fec_mpc52xx driverAsier Llano2009-12-081-59/+62
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | Fix the locking scheme on the fec_mpc52xx driver. This device can receive IRQs from three sources; the FEC itself, the tx DMA, and the rx DMA. Mutual exclusion was handled by taking a spin_lock() in the critical regions, but because the handlers are run with IRQs enabled, spin_lock() is insufficient and the driver can end up interrupting a critical region anyway from another IRQ. Asier Llano discovered that this occurs when an error IRQ is raised in the middle of handling rx irqs which resulted in an sk_buff memory leak. In addition, locking is spotty at best in the driver and inspection revealed quite a few places with insufficient locking. This patch is based on Asier's initial work, but reworks a number of things so that locks are held for as short a time as possible, so that spin_lock_irqsave() is used everywhere, and so the locks are dropped when calling into the network stack (because the lock only protects the hardware interface; not the network stack). Boot tested on a lite5200 with an NFS root. Has not been performance tested.

As we do not get the required bit value for the above IEs, crc over these IEs are never calculated, so any dynamic change in these IEs after the association is not really handled on 32-bit platforms.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Before issuing any firmware commands, we wait for the transmit rings to drain, to prevent control versus data path synchronization issues. In some cases, this can end up taking longer than the current hardcoded limit of 5 seconds, for example if the transmit rings are filled with packets for a host that has dropped off the air and we end up retransmitting every pending packet at the lowest rate a couple of times. This patch changes mwl8k_tx_wait_empty() to only bail out on timeout expiry if there was no change in the number of packets pending in the transmit rings during the waiting period. If at least one transmit ring entry was reclaimed while we were waiting, we are apparently still making progress, and we'll allow waiting for another timeout period.

Also, if the transmitted packet was a 4-address with QoS packet, the memmove() to do the needed header reshuffling would inadvertently overwrite the first two bytes of the packet payload with the QoS field.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Packets exchanged between the mwl8k driver and the firmware always have a 4-address header without QoS field. For QoS packets, the QoS field is passed to/from the firmware via the tx/rx descriptors. We were handling this correctly on transmit, but not on receive -- if a QoS packet was received, we would leave garbage in the QoS field in the packet passed up to the stack, which is Bad(tm). Also, if the packet received on the air was a 4-address without QoS packet, we would forget to skb_pull the 2-byte DMA length prefix off. This patch adds an argument to the ->rxd_process() receive descriptor operation to retrieve the QoS field from the receive descriptor, and extends mwl8k_remove_dma_header() to insert this field back into the packet if the packet received is a QoS packet. It also fixes mwl8k_remove_dma_header() to strip off the length prefix in all cases. Signed-off-by: Lennert Buytenhek <buytenh@marvell.com> Signed-off-by: John W. Linville <linville@tuxdriver.com>
| * mwl8k: fix UPDATE_STADB command struct legacy_rates array lengthLennert Buytenhek2009-12-071-38/+13
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | There exist 12 802.11b/g rates, but mwl8k supports two additional (non-standard) rates, and includes those rates in rate bitmasks and in its internal rate table that hardware rate indices index. Commit "mwl8k: report rate and other information for received frames" added one of the nonstandard rates to the mwl8k_rates table to make the OFDM rates in the table line up with the rate indices that are reported in the receive descriptor (so that we can just simply copy the receive descriptor rate index into ieee80211_rx_status::rate_idx) and bumped MWL8K_IEEE_LEGACY_DATA_RATES from 12 to 13, but this screwed up the UPDATE_STADB command struct layout, as it also uses that define, for its legacy_rates array. To avoid having to convert rate indices and legacy rate bitmaps (e.g. ieee80211_bss_conf::basic_rates) between the 12-rate mac80211 format and the 14-rate mwl8k format, we'll report all 14 rates in our wiphy's band, but filter out the nonstandard ones e.g. in the case of the UPDATE_STADB command which only accepts 12 rates. In the commands that accept 14 rates (SET_AID, SET_RATE), replace the use of the MWL8K_RATE_INDEX_MAX_ARRAY define in the command struct by the constant 14, to make it clearer that these commands accept 14 rates.

| * mac80211: Fix dynamic power save for scanning.Vivek Natarajan2009-12-072-4/+17
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Not only ps_sdata but also IEEE80211_CONF_PS is to be considered before restoring PS in scan_ps_disable(). For instance, when ps_sdata is set but CONF_PS is not set just because the dynamic timer is still running, a sw scan leads to setting of CONF_PS in scan_ps_disable instead of restarting the dynamic PS timer. Also for the above case, a null data frame is to be sent after returning to operating channel which was not happening with the current implementation. This patch fixes this too.

| * mac80211: recalculate idle later in MLMEJohannes Berg2009-12-071-2/+8
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | hwsim testing has revealed that when the MLME recalculates the idle state of the device, it sometimes does so before sending the final deauthentication or disassociation frame. This patch changes the place where the idle state is recalculated, but of course driver transmit is typically asynchronous while configuration is expected to be synchronous, so it doesn't fix all possible cases yet.

| | | | | | | | | | | | | | | | The bssid can be zero when null data template is set in wl1251_op_config(). It's enough, and especially safe, to set it once after association. Signed-off-by: Kalle Valo <kalle.valo@nokia.com> Signed-off-by: John W. Linville <linville@tuxdriver.com>
