| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | In certain circumstances, we can get an oops from a torn down device. Most notably this is from CD roms trying to call scsi_ioctl. The root cause of the problem is the fact that after scsi_remove_device() has been called, the queue is fully torn down. This is actually wrong since the queue can be used until the sdev release function is called. Therefore, we add an extra reference to the queue which is released in sdev->release, so the queue always exists.

Problem here is that usb_bulk_msg() on interrupt endpoint selfcorrects the call and changes requested pipe to interrupt type (see usb_bulk_msg). However with usb_interrupt_msg() on bulk endpoint does not correct the pipe type to bulk, but instead URB is submitted with interrupt type pipe. So pre-2.6.39 used usb_bulk_msg() and therefore worked with both endpoint types, however in 2.6.39 usb_interrupt_msg() with bulk endpoint causes ohci_hcd to fail submitted URB instantly with -ENOSPC and preventing zd1211rw from working with OHCI. Fix this by detecting endpoint type and using correct endpoint/pipe types for URB. Also fix asynchronous zd_usb_iowrite16v_async() to use right URB type on 'EP 4 OUT'.

The reason was that in passive scans there are no SSIDs, so there was a NULL pointer dereference. To solve the problem, we now check the number of SSIDs provided in the sched_scan request and only access the list if there's one or more (ie. passive scan is not forced). We also force all the channels to be passive by adding the IEEE80211_CHAN_PASSIVE_SCAN flag locally before the checks in the wl1271_scan_get_sched_scan_channels() function.

Previously we were using the same value as for normal passive scans. This adds some flexibility between these two different types of passive scan. For now we use 150 TUs for DFS channel dwell time.

This means that if the chip is asserting interrupt for some reason we can end up with a screaming IRQ that the interrupt handler is unable to deal with. Avoid this by only requesting the interrupt after we've reset the chip so we know what state it's in. This started manifesting itself on one of my boards in the past month or so, I suspect as a result of some core infrastructure changes removing some form of mitigation against bad behaviour here, even when things boot it seems that the new code brings the interface up more quickly.

Under heavy load, this causes fragmentation of memory. The present code releases the current buffer before checking to see if a new one is availble. Recovery from allocation failures is not possible, which results in kernel panics. The fix is to reorder the code to check that a new buffer can be allocated before the old one is released. If not possible, the received frame is dropped and the old one is reused. Without this change, it is impossible to transfer a 2 GB file without a kernel panic.

So for handling event only 4 more bytes needs to be pulled. This is achieved by changing event header length to 4. Almost all the events, except BA stream related and AMSDU aggregation control events, do not have the payload in their event skb. Such events handling depends only on the event ID. This event ID is the first four bytes of the event skb, which is copied to a separate variable before pulling the skb header. Hence event handling worked only for those events that didn't have payload in event skb. This patch fixes the broken event path of the events with payload in their event skb without harming existing working event path for the events without payload.

However the actual number can be changed to the power of 2 minus 1 form during the module initialization as alloc_disk() is called with (1 << part_shift) for some reason. So adjust 'max_part' also at least for consistency with loop and brd. It is exported via sysfs already, and a user should check this value after module loading if [s]he wants to use that number correctly (i.e. fdisk or something).

However if a user specifies very large value it would exceed the limitation of device minor number and can cause a kernel oops (or, at least, produce invalid device nodes in some cases). In addition, specifying large 'nbds_max' value causes same problem for the same reason.
