From 335f8514f200e63d689113d29cb7253a5c282967 Mon Sep 17 00:00:00 2001 From: Alan Cox Date: Thu, 11 Jun 2009 12:26:29 +0100 Subject: tty: Bring the usb tty port structure into more use This allows us to clean stuff up, but is probably also going to cause some app breakage with buggy apps as we now implement proper POSIX behaviour for USB ports matching all the other ports. This does also mean other apps that break on USB will now work properly.

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 Signed-off-by: Alan Cox Signed-off-by: Linus Torvalds --- drivers/usb/serial/sierra.c | 228 ++++++++++++++++++++++++++++---------------- 1 file changed, 144 insertions(+), 84 deletions(-) (limited to 'drivers/usb/serial/sierra.c') diff --git a/drivers/usb/serial/sierra.c b/drivers/usb/serial/sierra.c index 222a6230276..88ec7bfd9d3 100644 --- a/drivers/usb/serial/sierra.c +++ b/drivers/usb/serial/sierra.c @@ -26,12 +26,10 @@ #include #include #include -#include #define SWIMS_USB_REQUEST_SetPower 0x00 #define SWIMS_USB_REQUEST_SetNmea 0x07 -/* per port private data */ #define N_IN_URB 4 #define N_OUT_URB 4 #define IN_BUFLEN 4096 @@ -229,7 +227,6 @@ struct sierra_port_private { /* Input endpoints and buffers for this port */ struct urb *in_urbs[N_IN_URB];

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 Signed-off-by: Alan Cox Signed-off-by: Linus Torvalds --- drivers/usb/serial/sierra.c | 51 ++++++++++++++++++++++++++++++++++++++++++--- 1 file changed, 48 insertions(+), 3 deletions(-) (limited to 'drivers/usb/serial/sierra.c') diff --git a/drivers/usb/serial/sierra.c b/drivers/usb/serial/sierra.c index 88ec7bfd9d3..17ac34f4d66 100644 --- a/drivers/usb/serial/sierra.c +++ b/drivers/usb/serial/sierra.c @@ -37,6 +37,12 @@ static int debug; static int nmea; +/* Used in interface blacklisting */ +struct sierra_iface_info { + const u32 infolen; /* number of interface numbers on blacklist */ + const u8 *ifaceinfo; /* pointer to the array holding the numbers */ +}; + static int sierra_set_power_state(struct usb_device *udev, __u16 swiState) { int result; @@ -83,6 +89,23 @@ static int sierra_calc_num_ports(struct usb_serial *serial) return result; } +static int is_blacklisted(const u8 ifnum, + const struct sierra_iface_info *blacklist) +{ + const u8 *info; + int i; + + if (blacklist) { + info = blacklist->ifaceinfo; + + for (i = 0; i < blacklist->infolen; i++) { + if (info[i] == ifnum) + return 1; + } + } + return 0; +} + static int sierra_calc_interface(struct usb_serial *serial) { int interface; @@ -151,9 +174,25 @@ static int sierra_probe(struct usb_serial *serial, */ usb_set_serial_data(serial, (void *)num_ports); + /* ifnum could have changed - by calling usb_set_interface */ + ifnum = sierra_calc_interface(serial); + + if (is_blacklisted(ifnum, + (struct sierra_iface_info *)id->driver_info)) { + dev_dbg(&serial->dev->dev, + "Ignoring blacklisted interface #%d\n", ifnum); + return -ENODEV; + } + return result; } +static const u8 direct_ip_non_serial_ifaces[] = { 7, 8, 9, 10, 11 }; +static const struct sierra_iface_info direct_ip_interface_blacklist = { + .infolen = ARRAY_SIZE(direct_ip_non_serial_ifaces), + .ifaceinfo = direct_ip_non_serial_ifaces, +}; + static struct usb_device_id id_table [] = { { USB_DEVICE(0x1199, 0x0017) }, /* Sierra Wireless EM5625 */ { USB_DEVICE(0x1199, 0x0018) }, /* Sierra Wireless MC5720 */ @@ -186,9 +225,11 @@ static struct usb_device_id id_table [] = { { USB_DEVICE(0x1199, 0x6833) }, /* Sierra Wireless MC8781 */ { USB_DEVICE(0x1199, 0x683A) }, /* Sierra Wireless MC8785 */ { USB_DEVICE(0x1199, 0x683B) }, /* Sierra Wireless MC8785 Composite */ - { USB_DEVICE(0x1199, 0x683C) }, /* Sierra Wireless MC8790 */ - { USB_DEVICE(0x1199, 0x683D) }, /* Sierra Wireless MC8790 */ - { USB_DEVICE(0x1199, 0x683E) }, /* Sierra Wireless MC8790 */ + /* Sierra Wireless MC8790, MC8791, MC8792 Composite */ + { USB_DEVICE(0x1199, 0x683C) }, + { USB_DEVICE(0x1199, 0x683D) }, /* Sierra Wireless MC8791 Composite */ + /* Sierra Wireless MC8790, MC8791, MC8792 */ + { USB_DEVICE(0x1199, 0x683E) }, { USB_DEVICE(0x1199, 0x6850) }, /* Sierra Wireless AirCard 880 */ { USB_DEVICE(0x1199, 0x6851) }, /* Sierra Wireless AirCard 881 */ { USB_DEVICE(0x1199, 0x6852) }, /* Sierra Wireless AirCard 880 E */ @@ -209,6 +250,10 @@ static struct usb_device_id id_table [] = { { USB_DEVICE(0x1199, 0x0112) }, /* Sierra Wireless AirCard 580 */ { USB_DEVICE(0x0F3D, 0x0112) }, /* Airprime/Sierra PC 5220 */ + { USB_DEVICE(0x1199, 0x68A3), /* Sierra Wireless Direct IP modems */ + .driver_info = (kernel_ulong_t)&direct_ip_interface_blacklist + }, + { } }; MODULE_DEVICE_TABLE(usb, id_table); -- cgit v1.2.3-70-g09d2
