* libertas: move firmware lifetime handling to firmware.cDan Williams2013-10-185-26/+16Star
| | | | | | | | | | | | | Previously, each bus type was responsible for freeing the firmware structure, but some did that badly. Move responsibility for freeing firmware into firmware.c so that it's done once and correctly, instead of happening in multiple places in bus-specific code. This fixes a use-after-free bug found by Dr. H. Nikolaus Schaller where the SDIO code forgot to NULL priv->helper_fw after freeing it.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | The include file linux/ieee80211.h contains three definitions for the same thing in enum ieee80211_eid due to historic changes: /* Information Element IDs */ enum ieee80211_eid { : WLAN_EID_WPA = 221, WLAN_EID_GENERIC = 221, WLAN_EID_VENDOR_SPECIFIC = 221, : }; The standard refers to this as "vendor specific" element so the other two definitions are better not used.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | CMD_MAC_CONTROL is currently sent async to the firmware, and is sent from the lbs_setup_firmware() path during device init. This means that device init can complete with commands pending, and the if_sdio driver will sometimes power down the device (after init) with this command still pending. This was causing an occasional spurious command timeout after init, leading to a device reset. Fix this by making CMD_MAC_CONTROL synchronous when called from the lbs_setup_firmware() path.

However, the suspend handler currently tries to send host sleep commands (when wakeup params are set) in this configuration, causing a system hang when going into suspend (the commands will never complete).

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | We found a deadlock in the handling of command failures/reset conditions. For example: 1. Two commands are in the queue. 2. The first command is sent, but causes a timeout, which kicks off an asynchronous device reset 3. The second command is queued (but not yet sent to the hardware) 4. The device reset kicks in, causing the if_usb disconnect handler to set the "surprise removed" flag to be set as the device disappears from the bus. This causes lbs_thread to stop processing things ("adapter removed; waiting to die"), not processing any further commands, leaving the second queued command "in the air", causing a deadlock. Fix this by removing the surpriseremoved flag setting in if_usb. I can't see any reason why this needs to be done so early. lbs_remove_card will set this flag at an appropriate time - i.e. after all pending commands have been completed or cancelled, avoiding this deadlock.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Fail commands immediately when the request cannot be sent to the hardware. This solves the following deadlock: 1. Two commands are in the queue. 2. The first command is sent, but causes a timeout, which kicks off an asynchronous device reset 3. The second command is submitted to the device, and fails. The failure is noted but the existing code waits for the timeout handler to take care of the failure. 4. The device reset kicks in, causing the device "surprise removed" flag to be set as the device disappears from the bus. 5. lbs_thread notes this and enters "adapter removed; waiting to die" mode, without processing any further command timeouts. While adjusting lbs thread logic to handle this situation may be one way to fix this, it seems more practical to simplify handling of host_to_card failure so that the commands are failed immediately without waiting for more compliated timeout logic to kick in.

It's touches a lot of different parts of the kernel, all USB drivers, due to some API cleanups (getting rid of the ancient err() macro) and some changes that are needed for USB 3.0 power management updates. There are also lots of new drivers, pimarily gadget, but others as well. We deleted a staging driver, which was nice, and finally dropped the obsolete usbfs code, which will make Al happy to never have to touch that again. There were some build errors in the tree that linux-next found a few days ago, but those were fixed by the most recent changes (all were due to us not building with CONFIG_PM disabled.)

| * USB: Disable hub-initiated LPM for comms devices.Sarah Sharp2012-05-191-0/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Hub-initiated LPM is not good for USB communications devices. Comms devices should be able to tell when their link can go into a lower power state, because they know when an incoming transmission is finished. Ideally, these devices would slam their links into a lower power state, using the device-initiated LPM, after finishing the last packet of their data transfer. If we enable the idle timeouts for the parent hubs to enable hub-initiated LPM, we will get a lot of useless LPM packets on the bus as the devices reject LPM transitions when they're in the middle of receiving data. Worse, some devices might blindly accept the hub-initiated LPM and power down their radios while they're in the middle of receiving a transmission. The Intel Windows folks are disabling hub-initiated LPM for all USB communications devices under a xHCI USB 3.0 host. In order to keep the Linux behavior as close as possible to Windows, we need to do the same in Linux. Set the disable_hub_initiated_lpm flag for for all USB communications drivers. I know there aren't currently any USB 3.0 devices that implement these class specifications, but we should be ready if they do.

Add a new API for interface drivers to load their firmware asynchronously. The same semantics of the firmware table are followed like before. Interface drivers will be converted in follow-up patches, then we can remove the old, synchronous firmware loading function.

Remove the ability to pass custom "user" filenames to lbs_get_firmware(). Remove the ability to reprogram internal device memory with a different firmware from the USB driver (we don't know of any users), and simplify the OLPC firmware loading quirk to simply placing the OLPC firmware at the top of the list (we don't know of any users other than OLPC). Move lbs_get_firmware() into its own file. These simplifications should have no real-life effect but make the upcoming transition to asynchronous firmware loading considerably less painful.
