2017-10-16USB: serial: metro-usb: add MS7820 device idGravatar Johan Hovold 1-0/+1
Add device-id entry for (Honeywell) Metrologic MS7820 bar code scanner. The device has two interfaces (in this mode?); a vendor-specific interface with two interrupt endpoints and a second HID interface, which we do not bind to.

Make sure to reset the USB-console port pointer when console setup fails in order to avoid having the struct usb_serial be prematurely freed by the console code when the device is later disconnected.

2017-10-09USB: serial: console: fix use-after-free on disconnectGravatar Johan Hovold 1-1/+1
A clean-up patch removing two redundant NULL-checks from the console disconnect handler inadvertently also removed a third check. This could lead to the struct usb_serial being prematurely freed by the console code when a driver accepts but does not register any ports for an interface which also lacks endpoint descriptors.

2017-09-19USB: serial: cp210x: fix partnum regressionGravatar Sebastian Frei 1-6/+6
When adding GPIO support for the cp2105, the mentioned commit by Martyn Welch introduced a query for the part number of the chip. Unfortunately the driver aborts probing when this query fails, so currently the driver can not be used with chips not supporting this query. I have a data cable for Siemens mobile phones (ID 10ab:10c5) where this is the case. With this patch the driver can be bound even if the part number can not be queried.

Remove the broken alt_speed code, and warn when trying to set the line speed using TIOCSSERIAL and SPD flags. The use of SPD flags to set the line speed has been deprecated since v2.1.69 and support for alt_speed (e.g. "warp") has even been removed from TTY core in v3.10 by commit 6865ff222cca ("TTY: do not warn about setting speed via SPD_*"), effectively breaking all driver implementations of this except for serial core. Also remove the verbose and outdated comment on how to set baud rates. Note that setting a custom divisor will continue to work with the caveat that 38400 must again be selected every time the divisor is changed since v2.6.24 and commit 669a6db1037e ("USB: ftd_sio: cleanups and updates for new termios work") which started reporting back the actual baud rate used.

2017-06-13USB: serial: qcserial: expose methods for modem controlGravatar Magnus Lynch 1-0/+2
The qcserial driver fails to expose the .tiocmget and .tiocmset methods available from usb_wwan. These methods are required by ioctl commands dealing with the modem control signals DTR, RTS, etc. With these methods not set ioctl calls intended to control the DTR state will fail. For example, pppd drops and raises DTR in preparation to dialing the modem, which handles the case of the modem already being connected by making it hang up and return to command mode. DTR control being unavailable will lead to a protracted failure to connect as the modem will be stuck in a state not responsive to command. I have tested that with this patch the described case is handled successfully. There is an analogous method for .ioctl available from usb_wwan (as used in option.c) but I conservatively omitted that for lack of familiarity.

git://git.kernel.org/pub/scm/linux/kernel/git/johan/usb-serial into usb-next Johan writes: USB-serial updates for v4.12-rc1 Here are the USB-serial updates for 4.12, including: - support for devices with up to 16 ports (e.g. some Moxa devices) - support for endpoint sanity checks in core, which allows for code sharing and avoids allocating resources for rejected interfaces - support for endpoint-port remapping, which allows some driver hacks to be removed as well as omninet to use the generic write implementation - removal of an obsolete tty open-race workaround which prevented a port from being opened immediately after having been registered - generic-driver support for interfaces with just a bulk-in endpoint - improved ftdi_sio event-char and latency-timer handling - improved ftdi_sio support for some broken BM chips Included are also various clean ups and a new ftdi_sio device id. All have been in linux-next with no reported issues. Signed-off-by: Johan Hovold <johan@kernel.org>
2017-04-19USB: serial: ftdi_sio: add device ID for Microsemi/Arrow SF2PLUS Dev KitGravatar Marek Vasut 2-0/+7
This development kit has an FT4232 on it with a custom USB VID/PID. The FT4232 provides four UARTs, but only two are used. The UART 0 is used by the FlashPro5 programmer and UART 2 is connected to the SmartFusion2 CortexM3 SoC UART port. Note that the USB VID is registered to Actel according to Linux USB VID database, but that was acquired by Microsemi.

2017-04-10USB: serial: quatech2: drop redundant tty_buffer_request_roomGravatar Johan Hovold 1-3/+1
Drop redundant calls to tty_buffer_request_room and use the more efficient tty_insert_flip_char when inserting single characters. Signed-off-by: Johan Hovold <johan@kernel.org>
2017-04-10USB: serial: iuu_phoenix: drop excessive sanity checksGravatar Johan Hovold 1-6/+3
The transfer buffers and URBs are allocated and initialised by USB serial core during probe, and there's no need to check for NULL transfer buffers in the bulk-in completion handlers. Signed-off-by: Johan Hovold <johan@kernel.org>
2017-03-31USB: serial: drop obsolete open-race workaroundGravatar Johan Hovold 1-8/+0
Commit a65a6f14dc24 ("USB: serial: fix race between probe and open") fixed a race between probe and open, which could lead to crashes when a not yet fully initialised port was being opened. This race was later incidentally closed by commit 7e73eca6a7b2 ("TTY: move cdev_add to tty_register_device") which moved character-device registration from tty_register_driver to tty_register_device, which isn't called until the port has been fully set up. Remove the now redundant workaround which had the negative side effect of not allowing a port to be opened immediately after user space had been notified of a new tty device.

2017-03-29USB: serial: drop termios-flag debuggingGravatar Johan Hovold 5-42/+0
Drop some unnecessary termios-flag debugging that have been faithfully reproduced in a few old drivers, including the "clfag" typo and all. This also addresses a compiler warning on sparc where tcflag_t is unsigned long and would have required an explicit cast.

2017-03-28USB: serial: mxuport: add endpoint sanity checkGravatar Johan Hovold 1-0/+2
Add an explicit sanity check to make sure we have the expected endpoints. This will provide a descriptive error message in case an expected endpoint is missing when probing. Note that the driver already gracefully fails to probe (albeit with a less descriptive error message) if a bulk-in endpoint is missing, and an attempt to write to a port whose device lack a bulk-out endpoint would fail with -ENODEV.

2017-03-28USB: serial: mxuport: register two ports for unknown devicesGravatar Johan Hovold 1-11/+16
Print a message and register two ports for interfaces for which we do not know how many ports there are instead of binding, allocating resources, but not register any ports. This provides a hint that anyone adding a dynamic device id must also provide a reference id (driver info) from which the port count can be retrieved, for example: echo <vid> <pid> 0 0x110A 0x1410 > new_id Signed-off-by: Johan Hovold <johan@kernel.org>

2017-03-28USB: serial: visor: drop redundant calc_num_ports callbackGravatar Johan Hovold 1-1/+0
Drop the redundant calc_num_ports callback from the clie_5 type, for which the callback always returns zero and hence falls back to the type num_ports value (2). Signed-off-by: Johan Hovold <johan@kernel.org>
2017-03-28USB: serial: ti_usb_3410_5052: always require a bulk-out endpointGravatar Johan Hovold 1-0/+2
These devices always require at least one bulk-out endpoint so let core verify that. This avoids attempting to send bulk data to the default pipe when downloading firmware in boot mode. Note that further endpoints are still needed when not in boot mode. Signed-off-by: Johan Hovold <johan@kernel.org>
