2014-05-27USB: io_ti: fix firmware download on big-endian machines (part 2)Johan Hovold
A recent patch that purported to fix firmware download on big-endian machines failed to add the corresponding sparse annotation to the i2c-header. This was reported by the kbuild test robot. Adding the appropriate annotation revealed another endianess bug related to the i2c-header Size-field in a code path that is exercised when the firmware is actually being downloaded (and not just verified and left untouched unless older than the firmware at hand). This patch adds the required sparse annotation to the i2c-header and makes sure that the Size-field is sent in little-endian byte order during firmware download also on big-endian machines. Note that this patch is only compile-tested, but that there is no functional change for little-endian systems.

2014-04-25USB: io_ti: fix firmware download on big-endian machinesJohan Hovold
During firmware download the device expects memory addresses in big-endian byte order. As the wIndex parameter which hold the address is sent in little-endian byte order regardless of host byte order, we need to use swab16 rather than cpu_to_be16. Also make sure to handle the struct ti_i2c_desc size parameter which is returned in little-endian byte order.

2014-04-24USB: serial: fix sysfs-attribute removal deadlockJohan Hovold
Fix driver new_id sysfs-attribute removal deadlock by making sure to not hold any locks that the attribute operations grab when removing the attribute. Specifically, usb_serial_deregister holds the table mutex when deregistering the driver, which includes removing the new_id attribute. This can lead to a deadlock as writing to new_id increments the attribute's active count before trying to grab the same mutex in usb_serial_probe. The deadlock can easily be triggered by inserting a sleep in usb_serial_deregister and writing the id of an unbound device to new_id during module unload. As the table mutex (in this case) is used to prevent subdriver unload during probe, it should be sufficient to only hold the lock while manipulating the usb-serial driver list during deregister. A racing probe will then either fail to find a matching subdriver or fail to get the corresponding module reference. Since v3.15-rc1 this also triggers the following lockdep warning: ====================================================== [ INFO: possible circular locking dependency detected ] 3.15.0-rc2 #123 Tainted: G W ------------------------------------------------------- modprobe/190 is trying to acquire lock: (s_active#4){++++.+}, at: [<c0167aa0>] kernfs_remove_by_name_ns+0x4c/0x94 but task is already holding lock: (table_lock){+.+.+.}, at: [<bf004d84>] usb_serial_deregister+0x3c/0x78 [usbserial] which lock already depends on the new lock. the existing dependency chain (in reverse order) is: -> #1 (table_lock){+.+.+.}: [<c0075f84>] __lock_acquire+0x1694/0x1ce4 [<c0076de8>] lock_acquire+0xb4/0x154 [<c03af3cc>] _raw_spin_lock+0x4c/0x5c [<c02bbc24>] usb_store_new_id+0x14c/0x1ac [<bf007eb4>] new_id_store+0x68/0x70 [usbserial] [<c025f568>] drv_attr_store+0x30/0x3c [<c01690e0>] sysfs_kf_write+0x5c/0x60 [<c01682c0>] kernfs_fop_write+0xd4/0x194 [<c010881c>] vfs_write+0xbc/0x198 [<c0108e4c>] SyS_write+0x4c/0xa0 [<c000f880>] ret_fast_syscall+0x0/0x48 -> #0 (s_active#4){++++.+}: [<c03a7a28>] print_circular_bug+0x68/0x2f8 [<c0076218>] __lock_acquire+0x1928/0x1ce4 [<c0076de8>] lock_acquire+0xb4/0x154 [<c0166b70>] __kernfs_remove+0x254/0x310 [<c0167aa0>] kernfs_remove_by_name_ns+0x4c/0x94 [<c0169fb8>] remove_files.isra.1+0x48/0x84 [<c016a2fc>] sysfs_remove_group+0x58/0xac [<c016a414>] sysfs_remove_groups+0x34/0x44 [<c02623b8>] driver_remove_groups+0x1c/0x20 [<c0260e9c>] bus_remove_driver+0x3c/0xe4 [<c026235c>] driver_unregister+0x38/0x58 [<bf007fb4>] usb_serial_bus_deregister+0x84/0x88 [usbserial] [<bf004db4>] usb_serial_deregister+0x6c/0x78 [usbserial] [<bf005330>] usb_serial_deregister_drivers+0x2c/0x4c [usbserial] [<bf016618>] usb_serial_module_exit+0x14/0x1c [sierra] [<c009d6cc>] SyS_delete_module+0x184/0x210 [<c000f880>] ret_fast_syscall+0x0/0x48 other info that might help us debug this: Possible unsafe locking scenario: CPU0 CPU1 ---- ---- lock(table_lock); lock(s_active#4); lock(table_lock); lock(s_active#4); *** DEADLOCK *** 1 lock held by modprobe/190: #0: (table_lock){+.+.+.}, at: [<bf004d84>] usb_serial_deregister+0x3c/0x78 [usbserial] stack backtrace: CPU: 0 PID: 190 Comm: modprobe Tainted: G W 3.15.0-rc2 #123 [<c0015e10>] (unwind_backtrace) from [<c0013728>] (show_stack+0x20/0x24) [<c0013728>] (show_stack) from [<c03a9a54>] (dump_stack+0x24/0x28) [<c03a9a54>] (dump_stack) from [<c03a7cac>] (print_circular_bug+0x2ec/0x2f8) [<c03a7cac>] (print_circular_bug) from [<c0076218>] (__lock_acquire+0x1928/0x1ce4) [<c0076218>] (__lock_acquire) from [<c0076de8>] (lock_acquire+0xb4/0x154) [<c0076de8>] (lock_acquire) from [<c0166b70>] (__kernfs_remove+0x254/0x310) [<c0166b70>] (__kernfs_remove) from [<c0167aa0>] (kernfs_remove_by_name_ns+0x4c/0x94) [<c0167aa0>] (kernfs_remove_by_name_ns) from [<c0169fb8>] (remove_files.isra.1+0x48/0x84) [<c0169fb8>] (remove_files.isra.1) from [<c016a2fc>] (sysfs_remove_group+0x58/0xac) [<c016a2fc>] (sysfs_remove_group) from [<c016a414>] (sysfs_remove_groups+0x34/0x44) [<c016a414>] (sysfs_remove_groups) from [<c02623b8>] (driver_remove_groups+0x1c/0x20) [<c02623b8>] (driver_remove_groups) from [<c0260e9c>] (bus_remove_driver+0x3c/0xe4) [<c0260e9c>] (bus_remove_driver) from [<c026235c>] (driver_unregister+0x38/0x58) [<c026235c>] (driver_unregister) from [<bf007fb4>] (usb_serial_bus_deregister+0x84/0x88 [usbserial]) [<bf007fb4>] (usb_serial_bus_deregister [usbserial]) from [<bf004db4>] (usb_serial_deregister+0x6c/0x78 [usbserial]) [<bf004db4>] (usb_serial_deregister [usbserial]) from [<bf005330>] (usb_serial_deregister_drivers+0x2c/0x4c [usbserial]) [<bf005330>] (usb_serial_deregister_drivers [usbserial]) from [<bf016618>] (usb_serial_module_exit+0x14/0x1c [sierra]) [<bf016618>] (usb_serial_module_exit [sierra]) from [<c009d6cc>] (SyS_delete_module+0x184/0x210) [<c009d6cc>] (SyS_delete_module) from [<c000f880>] (ret_fast_syscall+0x0/0x48) Signed-off-by: Johan Hovold <jhovold@gmail.com> Cc: stable <stable@vger.kernel.org> Signed-off-by: Greg Kroah-Hartman <gregkh@linuxfoundation.org>
2014-04-16USB: usb_wwan: fix handling of missing bulk endpointsJohan Hovold
Fix regression introduced by commit 8e493ca1767d ("USB: usb_wwan: fix bulk-urb allocation") by making sure to require both bulk-in and out endpoints during port probe. The original option driver (which usb_wwan is based on) was written under the assumption that either endpoint could be missing, but evidently this cannot have been tested properly. Specifically, it would handle opening a device without bulk-in (but would blow up during resume which was implemented later), but not a missing bulk-out in write() (although it is handled in some places such as write_room()). Fortunately (?), the driver also got the test for missing endpoints wrong so the urbs were in fact always allocated, although they would be initialised using the wrong endpoint address (0) and any submission of such an urb would fail. The commit mentioned above fixed the test for missing endpoints but thereby exposed the other bugs which would now generate null-pointer exceptions rather than failed urb submissions. The regression was introduced in v3.7, but the offending commit was also marked for stable.

2014-01-07USB: ftdi_sio: added CS5 quirk for broken smartcard readersColin Leitner
Genuine FTDI chips support only CS7/8. A previous fix in commit 8704211f65a2 ("USB: ftdi_sio: fixed handling of unsupported CSIZE setting") enforced this limitation and reported it back to userspace. However, certain types of smartcard readers depend on specific driver behaviour that requests 0 data bits (not 5) to change into a different operating mode if CS5 has been set. This patch reenables this behaviour for all FTDI devices. Tagged to be added to stable, because it affects a lot of users of embedded systems which rely on these readers to work properly.

2014-01-03USB: ch341: fix ignored TIOCMIWAIT maskJohan Hovold
Make sure the TIOCMIWAIT mask is always honoured. The CH341 interrupt status has a multiple-status changed flag which indicates that multiple status changes has occurred since last interrupt event. Unfortunately, if the final status is the same, there appears to be no way to determine which signal(s) has changed (an even number of times). This means that the multiple-status flag should not be used in TIOCMIWAIT as it leads to the signal mask argument being ignored (e.g. TIOCMIWAIT could return if DSR changes twice, even though the user only cares about carrier changes).
