2009-06-11sierra: driver interface blacklistingElina Pasheva
Interface blacklisting is necessary for non-serial interfaces that are handled by a different driver. The interface blacklisting is implemented in sierra driver per device. Each device in need of a blacklist has a static information array kept in the driver. This array contains the interface numbers that are blacklisted. The pointer for each blacklist array and the length of that blacklist are 'bundled' in data structure sierra_iface_info. A pointer to this information is set in id_table when the device is added to the id_table. The following is summary of changes we have made to sierra.c driver in this patch dealing with interface blacklisting support: - Added data structure sierra_iface_info and function is_blacklisted() to support blacklisting - Modified sierra_probe() to handle blacklisted interfaces accordingly - Improved comments in id_table - Added new device in id_table with blacklist interface support Signed-off-by: Elina Pasheva <epasheva@sierrawireless.com> Signed-off-by: Alan Cox <alan@linux.intel.com> Signed-off-by: Linus Torvalds <torvalds@linux-foundation.org>
2009-06-11sierra: driver urb handling improvementsElina Pasheva
[Folded from eight patches into one as the original set according to the author "All of the patches need to be applied to obtain a working product" so keeping them split seems unhelpful Merge fixes done versus other conflicting changes and moved the spin_lock_init from open to setup time -- Alan] Summary of the changes and code re-organization in this patch: - The memory for urbs is allocated and urbs are submitted only for the active interfaces (instead of pre-allocating these for all interfaces). This will save memory especially in the case of using composite devices. - The code has been re-organized and functionality has been extracted from sierra_startup(), sierra_shutdown(), sierra_open(), sierra_close() and added in helper functions sierra_release_urb(), sierra_stop_rx_urbs(), sierra_submit_rx_urbs() and sierra_setup_urb() - Added function sierra_release_urb() to free an urb and its transfer buffer. - Removed unecessary include file reference and comment. - Added function sierra_stop_rx_urbs() that takes care of the release of receive and interrupt urbs. This function is to be called by sierra_close() whenever an interface is de-activated. - Added new function sierra_submit_rx_urbs() that handles the submission of receive urbs and interrupt urbs (if any) during the interface activation. This function is to be called by sierra_open(). Added a second parameter to pass the memory allocation (as suggested by Oliver Neukum) so that this function can be used in post_reset() and resume(). - Added new function sierra_setup_urb() that contains the functionality to allocate an urb, fill bulk urb using the supplied memory allocation flag and release urb upon error. Added parameter so that the caller pass the memory allocation flag for flexibility. - Moved sierra_close() before sierra_open() to resolve dependencies introduced by the code reorganization. - Modified sierra_close() to call sierra_stop_rx_urbs() and sierra_release_urb() functions added in previous patch. - Modified sierra_open() to call sierra_setup_urb() and sierra_submit_rx_urbs() functions; note urbs are allocated and submitted for each activated interface. - Modified sierra_startup() so that allocation of urbs happens whenever an interface is activated (urb allocation is moved to sierra_open()). - Modified sierra_shutdown() so that urbs are freed whenever an interface is de-activated (urb freeing moved to sierra_close() as shown in previous patch from the series) - Removed unecessary data structure from sierra_port_private_data - Suppress an entry in logs by not re-submitting an urb when usb_submit_urb() returns -EPERM, as this shows that usb_kill_urb() is running (as suggested by Oliver Neukum) Signed-off-by: Elina Pasheva <epasheva@sierrawireless.com> Signed-off-by: Alan Cox <alan.cox@linux.intel.com> Signed-off-by: Linus Torvalds <torvalds@linux-foundation.org>

2009-05-28usb-serial: fix crash when sub-driver updates firmwareAlan Stern
This patch (as1244) fixes a crash in usb-serial that occurs when a sub-driver returns a positive value from its attach method, indicating that new firmware was loaded and the device will disconnect and reconnect. The usb-serial core then skips the step of registering the port devices; when the disconnect occurs, the attempt to unregister the ports fails dramatically. This problem shows up with Keyspan devices and it might affect others as well. When the attach method returns a positive value, the patch sets num_ports to 0. This tells usb_serial_disconnect() not to try unregistering any of the ports; instead they are cleaned up by destroy_serial().

2009-05-28USB: isp1760: urb_dequeue doesn't always find the urbsWarren Free
The option driver (and presumably others) allocates several URBs when it opens and tries to free them when it closes. The isp1760_urb_dequeue function gets called, but the packet being dequeued is not necessarily at the front of one of the 32 queues. If not, the isp1760_urb_done function doesn't get called for the URB and the process trying to free it hangs forever on a wait_queue. This patch does two things. If the URB being dequeued has others queued behind it, it re-queues them. And it searches the queues looking for the URB being dequeued rather than just looking at the one at the front of the queue.

2009-05-18Fix oops on close of hot-unplugged FTDI serial converterDavid Woodhouse
Commit c45d6320 ("fix reference counting of ftdi_private") stopped ftdi_sio_port_remove() from directly freeing the port-private data, with the intention if the port was still open, it would be freed when ftdi_close() is eventually called and releases the last refcount on the structure. That's all very well, but ftdi_sio_port_remove() still contains a call to usb_set_serial_port_data(port, NULL) -- so by the time we get to ftdi_close() for the port which was unplugged, it _still_ oopses on dereferencing that NULL pointer, as it did before (and does in 2.6.29). The fix is just not to clear the private data in ftdi_sio_port_remove(). Then the refcount is properly reduced to zero when the final kref_put() happens in ftdi_close(). Remove a bogus comment too, while we're at it. And stop doing things inside "if (priv)" -- it must _always_ be there. Based loosely on an earlier patch by Daniel Mack, and suggestions by Alan Stern.

The resulting schedule looks like this: uframe 0: 188-byte isoc-OUT SSPLIT, 8-byte int-IN SSPLIT uframe 1: 4-byte isoc-OUT SSPLIT The SSPLITs are intermingled, causing an error in the downstream hub's TT.

2009-04-23USB: serial: fix lifetime and locking problemsAlan Stern
This patch (as1229) fixes a few lifetime and locking problems in the usb-serial driver. The main symptom is that an invalid kevent is created when the serial device is unplugged while a connection is active. Ports should be unregistered when device is disconnected, not when the parent usb_serial structure is deallocated. Each open file should hold a reference to the corresponding port structure, and the reference should be released when the file is closed. serial->disc_mutex should be acquired in serial_open(), to resolve the classic race between open and disconnect. serial_close() doesn't need to hold both serial->disc_mutex and port->mutex at the same time. Release the subdriver's module reference only after releasing all the other references, in case one of the release routines needs to invoke some code in the subdriver module. Replace a call to flush_scheduled_work() (which is prone to deadlocks) with cancel_work_sync(). Also, add a call to cancel_work_sync() in the disconnect routine. Reduce the scope of serial->disc_mutex in serial_disconnect(). The only place it really needs to protect is where the "disconnected" flag is set.

2009-04-17WUSB: correct format of wusb_chid sysfs fileDavid Vrabel
Make the wusb_chid sysfs file match the ABI documentation. Print all zeros if the WUSB host is stopped (instead of an empty file) and end the file with a newline. Signed-off-by: David Vrabel <david.vrabel@csr.com> Signed-off-by: Greg Kroah-Hartman <gregkh@suse.de>
