| * devcoredump: add scatterlist supportAviya Erenfeld2016-04-151-2/+2
| | | | | | | | | | | | | | | | | | | | | | | | | | | | Add scatterlist support (dev_coredumpsg) to allow drivers to avoid vmalloc() like dev_coredumpm(), while also avoiding the module reference that the latter function requires. This internally uses dev_coredumpm() with function inside the devcoredump module, requiring removing the const (which touches the driver using it.)

This broke 7265D whose firmware does advertise IWL_UCODE_TLV_CAPA_EXTEND_SHARED_MEM_CFG but doesn't have 2 CPUs. The current code does check the length of the FIFO before dumping them (and the nonexistent FIFO has a 0 length), but we still accessed a register to set the FIFO number and that made the DMA unhappy. The impact was a much longer recovery upon firmware assert.

This indeed works for the regular case, since we shouldn't cross the 2048 boundary without getting a frame release notification. However, this is problematic due to packet filtering that may be performed by the FW while we are in d0i3. Theoretically we may filter over 2048 packets, and then the check of the NSSN will get incorrect. Change the comparison to always trust nssn unless it is 64 or less frames behind the head - which might happen due to a timeout. This new comparison is to be used only when comparing reorder buffer head with nssn, and not when comparing the packet SN to nssn or reorder buffer head. Put this in a separate commit as the logic is a bit tricky and stands for its own commit message.

This is needed since some APs do not retransmit frames to fill in the reorder holes and in TCP it results with a complete stall of traffic. This has a few side effects on the general design: The nssn may not reflect the the head of the reorder buffer. This situation is valid, and packets with SN lower than the reorder buffer head will be dropped. Another side effect is that since the reorder timer might expire we need to lock the reorder buffer. This however is fine since the locking is only inside a single reorder buffer between RX path and reorder timeout and there is no outside contention.

This logic can create holes in reorder buffer since packets that belong to other stream were directed to a different core. However, those are valid holes and the packets can be indicated in L3 order. The hardware will utilize a mechanism of informing the driver of the normalized ssn and the driver shall release all packets that SN is lower than the nssn. This enables managing the reorder across the queues without sharing any data between them. The reorder buffer is allocated and released directly in the RX path in order to avoid various races between control path and rx path. The code utilizes the internal messaging to notify rx queues of when to delete the reorder buffer.

| | * | iwlwifi: mvm: add infrastructure for tracking BA session in driverSara Sharon2016-05-106-13/+194
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | According to the spec when a BA session is started there is a timeout set for the session in the ADDBA request. If there is not activity on the TA/TID then the session expires and a DELBA is sent. In order to check for the timeout, data must be shared among the rx queues. Add a timer that runs as long as BA session is active for the station and stops aggregation session if needed. This patch also lays the infrastructure for the reordering buffer which will be enabled in the next patches.

| | * | iwlwifi: mvm: change RX sync notification to be an attribute and not a typeSara Sharon2016-05-104-20/+37
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Currently the sync notification is a type of notification. However, it is better fitted as an attribute of a notification, since there might be another message in the payload (delba for instance) that should be sent while control path is waiting for all queues to process.

| | * | iwlwifi: mvm: implement driver RX queues sync commandSara Sharon2016-05-105-0/+58
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | mac80211 will call the driver whenever there is a race between RSS queues and control path that requires a processing of all pending frames in RSS queues. Implement that by utilizing the internal notification mechanism: queue a message to all queues. When the message is received on a queue it decrements the atomic counter. This guarantees that all pending frames in the RX queue were processed since the message is in order inside the queue.

* | | | | iwlwifi: fix mis-merge that breaks the driverLinus Torvalds2016-05-181-1/+2

It would fail with a "Microcode SW error detected." and spew out register state over and over again without ever connecting to the network. The cause is mis-merge in commit 909b27f70643, where David seems to have lost some of the changes to iwl_mvm_set_tx_cmd() from commit 5c08b0f5026f ("iwlwifi: mvm: don't override the rate with the AMSDU len"). The reason seems to be a conflict with commit d8fe484470dd ("iwlwifi: mvm: add support for new TX CMD API"), which touched a line adjacent to the changes in 909b27f70643. David missed the fact that "info->driver_data[0]" had become "skb_info->driver_data[0]". Then he removed the skb_info because it was unused. This just re-updates iwl_mvm_set_tx_cmd() with the lost two lines.

Each A-MSDU is an skb and skb->len doesn't include the number of bytes which need to be added for the headers being added (subframe header, TCP header, IP header, SNAP, padding). To be able to set the right value in the Tx command, we put the number of bytes added by those headers in driver_data in iwl_mvm_tx_tso and use this value in iwl_mvm_set_tx_cmd. The problem by setting this value in driver_data is that it overrides the ieee80211_tx_info. The bug manifested itself when we send P2P related frames in CCK since the rate in ieee80211_tx_info is zero-ed. This of course is a violation of the P2P specification. To fix this, copy the original ieee80211_tx_info to the stack and pass it to the functions which need it. Assign the number of bytes added by the headers to the driver_data inside the skb itself.
