* Bluetooth: Fix false errors from bcsp_pkt_cull functionWending Weng2009-08-24
| | | | | | | | | | | | | | | | | | | | | | | | The error message "Removed only %u out of %u pkts" is printed when multiple to be acked packets are queued. if (i++ >= pkts_to_be_removed) break; This will break out of the loop and increase the counter i when i==pkts_to_be_removed and the loop ends up with i=pkts_to_be_removed+1. The following line if (i != pkts_to_be_removed) { BT_ERR("Removed only %u out of %u pkts", i, pkts_to_be_removed); } will then display the false message. The counter i must not increase on the same statement. Signed-off-by: Wending Weng <wweng@rheinmetall.ca> Signed-off-by: Marcel Holtmann <marcel@holtmann.org>
* Bluetooth: Add missing kmalloc NULL tests to Marvell driverJulia Lawall2009-08-22
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Check that the result of kmalloc is not NULL before dereferencing it. The patch also replaces kmalloc + memset by kzalloc. The semantic match that finds this problem is as follows: (http://coccinelle.lip6.fr/) // <smpl> @@ expression *x; identifier f; constant char *C; @@ x = \(kmalloc\|kcalloc\|kzalloc\)(...); ... when != x == NULL when != x != NULL when != (x || ...)

* Bluetooth: Fix incorrect alignment in Marvell BT-over-SDIO driverBing Zhao2009-08-22
| | | | | | | | | The driver uses "u32" for alignment check and calculation which works only on 32-bit system. It will crash the 64-bit system. Replace "u32" with "unsigned long" to fix this issue. Signed-off-by: Bing Zhao <bzhao@marvell.com> Signed-off-by: Marcel Holtmann <marcel@holtmann.org>
* Bluetooth: Remove Enter/Leave debug statements from Marvell driverMarcel Holtmann2009-08-22
| | | | | | | | | The Marvell Bluetooth driver is full of Enter/Leave debug statements and all of them are really pointless and only clutter the code. Seems to be some left-overs when they ported the driver from Windows. For the Linux driver lets remove these. Signed-off-by: Marcel Holtmann <marcel@holtmann.org>

| | | | | | | | The Marvell driver has some weird quirks on how to construct proper SKBs with Bluetooth HCI commands. Fix it to use skb_put properly and also use hci_opcode_pack instead of self-crafted macro. Signed-off-by: Marcel Holtmann <marcel@holtmann.org>

* Bluetooth: Fix complicated assignment of firmware for Marvell devicesMarcel Holtmann2009-08-22
| | | | | | | | | | | The Marvell Bluetooth SDIO driver has a really complicated concept on how firmware names are assigned to specific device ids. Fix that by doing a proper structure and assign it to the module device table. And while at it fix various coding style weirdness that is still present in this driver.

* Bluetooth: Remove pointless ifdef protection for Marvell header filesMarcel Holtmann2009-08-22
| | | | | | | | | Both header files of the Marvell Bluetooth driver are private anyway and if the driver happens to include them twice or they create a circular dependency then the driver needs fixing. So just remove both pointless ifdefs. Signed-off-by: Marcel Holtmann <marcel@holtmann.org>
* Bluetooth: Fix compilation of Marvell driver without debugfsMarcel Holtmann2009-08-22
| | | | | | | | | The Makefile entry for the Marvell driver is broken when it comes to handling the optional DEBUG_FS correctly. That must have been the reason why they were using select in Kconfig in the first place. Fix this and make it really optional. Signed-off-by: Marcel Holtmann <marcel@holtmann.org>
* Bluetooth: Fix Kconfig for Marvell Bluetooth driverMarcel Holtmann2009-08-22
| | | | | | | | | | The Marvell driver selects DEBUG_FS and FW_LOADER for its core driver and that is pointless. Don't select DEBUG_FS since it is either enabled or not and it is not for the driver to enable it. Also FW_LOADER is only used within the SDIO driver and so just have that one select the FW_LOADER option. Signed-off-by: Marcel Holtmann <marcel@holtmann.org>

| * mwl8k: fix firmware command serialisationLennert Buytenhek2009-08-20
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The current mwl8k_priv->fw_lock spinlock doesn't actually protect against multiple commands being submitted at once, as it is not kept held over the entire firmware command submission. And since waiting for command completion sleeps, we can't use a spinlock anyway. To fix mwl8k firmware command serialisation properly, we have the following requirements: - Some commands require that the packet transmit path is idle when the command is issued. (For simplicity, we'll just quiesce the transmit path for every command.) - There are certain sequences of commands that need to be issued to the hardware sequentially, with no other intervening commands. This leads to an implementation of a "firmware lock" as a mutex that can be taken recursively, and which is taken by both the low-level command submission function (mwl8k_post_cmd) as well as any users of that function that require issuing of an atomic sequence of commands, and quiesces the transmit path whenever it's taken.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Delete most of the mwl8k_work_struct fields and options, since most of them are unused or never changed from their defaults: - We always use priv->config_wq, so delete the wqueue argument from mwl8k_queue_work(). - MWL8K_WQ_SPIN and MWL8K_WQ_POST_REQUEST are never used, as all callers sleep for request completion, so sleep unconditionally. - MWL8K_WQ_FREE_WORKSTRUCT is never used. - MWL8K_WQ_TX_WAIT_EMPTY is always set, so assume it unconditionally. - timeout_ms/txwait_attempts/tx_timeout_ms are never changed from their defaults, so just hardcode these in the workqueue worker. - step is never used.

| * mwl8k: dma header manipulations can't failLennert Buytenhek2009-08-20
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Adding and removing the DMA header that the mwl8k hardware requires on tx and provides on rx can never fail, since we are guaranteed to have enough headroom on the tx path to expand the packet, and we only ever shrink the packet on the rx path. (And on both paths we are guaranteed to be the only user of the skb we are handling.) This allows removing all of the skb clone handling in the tx and tx reclaim paths, and eliminates error checks in both the tx and rx paths, simplifying the code a bit more.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | mwl8k_configure_filter() passes pointers to total_flags and the multicast address list to a workqueue function, while there is no guarantee that those pointers will still be valid by the time the workqueue function runs. Solve this by passing total_flags by value, and by passing an already built multicast address setup command packet to the workqueue function so that we don't have to look at the multicast address list itself outside of mwl8k_configure_filter(). Also, since ->configure_filter() can sleep now, wait synchronously for the worker to finish. Signed-off-by: Lennert Buytenhek <buytenh@marvell.com> Signed-off-by: John W.
