[PATCH, take 2] libertas: reduce command retry time In the normal case, an unsuccessful command would be retried for 10*5 seconds, or 10*10 seconds in the worst case. This patch reduces this to 3*3 seconds, or 3*10 seconds in the worst case. I also reduced the time it takes to start a new command downloaded. Signed-off-by:

In case the hash grow failed, it is not fair to return error - the new node _was_ _actually_ added in this case. Besides, after my previous patch, this grow is more likely to fail on large hashes. Signed-off-by:

The mesh_path_node_copy() can be called like this: mesh_path_add `- write_lock(&pathtbl_resize_lock); /* ! */ `- mesh_table_grow `- ->copy_node `- mesh_path_node_copy thus, the GFP_KERNEL is not suitable here. The acceptable fix, I suppose, is make this allocation GPF_ATOMIC - the mpath_node being allocated is 4 pointers, i.e. this allocation is small enough to survive even under a moderate memory pressure.

The mesh_path_node_copy() performs kmalloc() and thus - may fail (well, it does not now, but I'm fixing this right now). Its caller - the mesh_table_grow() - isn't prepared for such a trick yet. This preparation is just flush the new hash and make copy_node() return an int value. Signed-off-by:

(This set applies OK without the previous one of 4 patches, but with some fuzz in the 7th one) The mesh_path_node_free() does so under hashwlock. But, this one is called 1. from mesh_path_add() after an old hash is hidden and synchronize_rcu() is calld 2. mesh_pathtbl_unregister(), when the module is being unloaded and no devices exist to mess with this hash. So, it seems to me, that simply removing the call is OK. Signed-off-by:

There are already tree paths, that do incremental rollbacks, so merge them together, rename labels and format the code to look a bit nicer. (I do not mind dropping/delaying this patch however). Signed-off-by:

This patch is based on a patch from Shailendra Govardhan and Brian Cavagnolo. It extends the MESH_CONFIG command to configure non-volatile parameters on libertas devices that support them (e.g. OLPC Active Antenna). This patch only implements the driver/firmware interface. See http://dev.laptop.org/ticket/6823 for minimal testing results and known issues. Signed-off-by:

We weren't properly handling multicast on the mesh interface. Fix that, which involves setting up the hardware to use the union of dev->mc_list for both eth%d and msh%d devices. This means we can't do it directly from ->set_multicast_list() because we'd need to lock the other device to read its list, and we can't do that because it might deadlock. So punt the actual work to keventd. Also, invoke the same when taking an interface down; for some reason the core calls ->set_multicast_list while IFF_UP is still set in dev->flags when we're taking it down, so its addresses don't get removed then. We also convert MAC_MULTICAST_ADR to a direct command while we're at it, removing one more entry from the big switch statement in the deprecated lbs_prepare_and_send_command() function.

Using the deprecated lbs_prepare_and_send_command() function for a command which it doesn't understand is an error; complain loudly about it even when we're not debugging. The mesh stats bug, where we converted MESH_ACCESS to a direct command but accidentally missed one user which was still trying to do it through lbs_prepare_and_send_command(), would have been caught a lot quicker if we'd done this sooner. Such bugs aren't entirely unlikely in future too, as we convert more code to stop using this function. Signed-off-by:

With the pending removal of the tx_control structure we can merge the RX and TX entry private data structure in advance. This will temporarily increase the required memory for the queue, but that overhead will only be limited. Signed-off-by:

the rxdesc structure is properly memsetted before passed to the driver. This means we don't have to reinitialize the flags and dev_flags fields in the drivers again. This will prevent problems when the rxdone handler is adding flags in a earlier status and will make the code look nicer when we are adding more read attributes in the rxdone handler in the driver.

Split rt2x00lib_write_tx_desc() up into a TX descriptor initializor and TX descriptor writer. This split is required to properly allow mac80211 to move its tx_control structure into the skb->cb array. The rt2x00queue_create_tx_descriptor() function will read all tx control information and convert it into a rt2x00 TX descriptor information structure. After that function is complete, we have all information we needed from the tx control structure and are free to start writing into the skb->cb array for our own purposes. rt2x00queue_write_tx_descriptor() will be in charge of really sending the TX descriptor to the hardware and kicking the TX queue.

In preparation of replacing the statically allocated data DMA buffers with DMA-mapped skb's we need to change the TXD handling of the PCI drivers, by moving the programming of the buffer address fields to the actual TXD writing at TX time, instead of at start-up time. Signed-off-by:

Due to usage of memmove() in rt2x00usb the descriptor can become corrupted because it is being overwritten by the data part. Overall having the descriptor in front of the frame is a bad idea, we can however use the skb->cb array for this task, since that contains more then enough room to hold the entire descriptor and preserve the information long enough. After this we can also cleanup the alignment code a bit to make it work a bit more flexible to allow for all kinds of odd header lengths. Signed-off-by:

With the integration of the mac80211 multiqueue patches it has become possible that the mac80211 layer modifies the number of TX queues that is stored inside the ieee80211_hw structure, especially when multi-queue is not selected. The rt2x00 drivers are not well suited to handle that situation, as they allocate the queue structures before mac80211 has modified the number of queues it is going to use, and also expect the number of allocated queues to match the hardware implementation. Hence, ensure that rt2x00 maintains by itself the number of queues that the hardware supports, and, at the same time, making is not dependent on the preservation of contents inside a mac80211 structure.

Move the last remaining information details read from ieee80211_tx_control in the drivers to the txentry_desc structure. After this we can remove ieee80211_tx_control from the argument list for the callback function, which makes it easier when the control information is moved into skb->cb Signed-off-by:

The tx_status enumeration was broken since the introduction of rt61pci. That driver uses different values to report the status of the tx action. This would lead to frames that were reported as success but actually failed to be send out, or frames that were neither successfull or failure which were reported as failure. Fix this by change the TX status reporting and more explicitely check for failure or success. Note that a third possibility is added "unknown". Not all hardware (USB) can report the actual TX status, for rt61pci some frames will receive this status because the TXdone handler is never called for those frames. This unknown will now be handled as neither success or failure, so we no longer increment the failure counter while this conclusion could not be determined from the real status of the frame.

Remove frame_type from skb_frame_desc and pass it as argument to rt2x00debug_dump_frame(). Change data_len and desc_len to unsigned short to save another 4 bytes in skb_frame_desc. Note that this was the only location where the data_len and desc_len was not yet treated as unsigned short. This trim is required to help mac80211 with adding the TX control and TX status informtation into the skb->cb structure. When that happens, drivers will have approximately 40 bytes left to use freely. Signed-off-by:

This patch modifies TIPC's network topology service so that it only requires a single reference table entry per subscriber connection, rather than two. This is achieved by letting the reference to the server port communicating with the subscriber act as the reference to the subscriber object itself. (Since the subscriber cannot exist without its port, and vice versa, this dual role for the reference is perfectly natural.) This consolidation reduces the size of the reference table by 50% in the default configuration. Signed-off-by:

This patch fixes TIPC's topology server so that it does byte swapping correctly when endianness conversion is required. (Note: This bug only impacted an application if it issues a subscription request to a topology server on another node, rather than the server on it's own node; since the topology server is normally not accessible by off-node applications, most TIPC applications were not impacted by the bug.)

Instead of assigning values for the struct cpu_reg's at runtime, we already know these values at compile time. Therefore, we can use designated initializers, to initialize these structures and not have to incur this assignment cost at run-time. Signed-off-by:
