2012-08-10usb: usb_wwan: replace release and disconnect with a port_remove hookBjørn Mork1-3/+2
Doing port specific cleanup in the .port_remove hook is a lot simpler and safer than doing it in the USB driver .release or .disconnect methods. The removal of the port from the usb-serial bus will happen before the USB driver cleanup, so we must be careful about accessing port specific driver data from any USB driver functions. This problem surfaced after the commit 0998d0631 device-core: Ensure drvdata = NULL when no driver is bound which turned the previous unsafe access into a reliable NULL pointer dereference. Fixes the following Oops: [ 243.148471] BUG: unable to handle kernel NULL pointer dereference at (null) [ 243.148508] IP: [<ffffffffa0468527>] stop_read_write_urbs+0x37/0x80 [usb_wwan] [ 243.148556] PGD 79d60067 PUD 79d61067 PMD 0 [ 243.148590] Oops: 0000 [#1] SMP [ 243.148617] Modules linked in: sr_mod cdrom qmi_wwan usbnet option cdc_wdm usb_wwan usbserial usb_storage uas fuse af_packet ip6table_filter ip6_tables iptable_filter ip_tables x_tables tun edd cpufreq_conservative cpufreq_userspace cpufreq_powersave snd_pcm_oss snd_mixer_oss acpi_cpufreq snd_seq mperf snd_seq_device coretemp arc4 sg hp_wmi sparse_keymap uvcvideo videobuf2_core videodev videobuf2_vmalloc videobuf2_memops rtl8192ce rtl8192c_common rtlwifi joydev pcspkr microcode mac80211 i2c_i801 lpc_ich r8169 snd_hda_codec_idt cfg80211 snd_hda_intel snd_hda_codec rfkill snd_hwdep snd_pcm wmi snd_timer ac snd soundcore snd_page_alloc battery uhci_hcd i915 drm_kms_helper drm i2c_algo_bit ehci_hcd thermal usbcore video usb_common button processor thermal_sys [ 243.149007] CPU 1 [ 243.149027] Pid: 135, comm: khubd Not tainted 3.5.0-rc7-next-20120720-1-vanilla #1 Hewlett-Packard HP Mini 110-3700 /1584 [ 243.149072] RIP: 0010:[<ffffffffa0468527>] [<ffffffffa0468527>] stop_read_write_urbs+0x37/0x80 [usb_wwan] [ 243.149118] RSP: 0018:ffff880037e75b30 EFLAGS: 00010286 [ 243.149133] RAX: 0000000000000000 RBX: 0000000000000000 RCX: ffff88005912aa28 [ 243.149150] RDX: ffff88005e95f028 RSI: 0000000000000000 RDI: ffff88005f7c1a10 [ 243.149166] RBP: ffff880037e75b60 R08: 0000000000000000 R09: ffffffff812cea90 [ 243.149182] R10: 0000000000000000 R11: 0000000000000001 R12: ffff88006539b440 [ 243.149198] R13: ffff88006539b440 R14: 0000000000000000 R15: 0000000000000000 [ 243.149216] FS: 0000000000000000(0000) GS:ffff88007ee80000(0000) knlGS:0000000000000000 [ 243.149233] CS: 0010 DS: 0000 ES: 0000 CR0: 000000008005003b [ 243.149248] CR2: 0000000000000000 CR3: 0000000079fe0000 CR4: 00000000000007e0 [ 243.149264] DR0: 0000000000000000 DR1: 0000000000000000 DR2: 0000000000000000 [ 243.149280] DR3: 0000000000000000 DR6: 00000000ffff0ff0 DR7: 0000000000000400 [ 243.149298] Process khubd (pid: 135, threadinfo ffff880037e74000, task ffff880037d40600) [ 243.149313] Stack: [ 243.149323] ffff880037e75b40 ffff88006539b440 ffff8800799bc830 ffff88005f7c1800 [ 243.149348] 0000000000000001 ffff88006539b448 ffff880037e75b70 ffffffffa04685e9 [ 243.149371] ffff880037e75bc0 ffffffffa0473765 ffff880037354988 ffff88007b594800 [ 243.149395] Call Trace: [ 243.149419] [<ffffffffa04685e9>] usb_wwan_disconnect+0x9/0x10 [usb_wwan] [ 243.149447] [<ffffffffa0473765>] usb_serial_disconnect+0xd5/0x120 [usbserial] [ 243.149511] [<ffffffffa0046b48>] usb_unbind_interface+0x58/0x1a0 [usbcore] [ 243.149545] [<ffffffff8139ebd7>] __device_release_driver+0x77/0xe0 [ 243.149567] [<ffffffff8139ec67>] device_release_driver+0x27/0x40 [ 243.149587] [<ffffffff8139e5cf>] bus_remove_device+0xdf/0x150 [ 243.149608] [<ffffffff8139bc78>] device_del+0x118/0x1a0 [ 243.149661] [<ffffffffa0044590>] usb_disable_device+0xb0/0x280 [usbcore] [ 243.149718] [<ffffffffa003c6fd>] usb_disconnect+0x9d/0x140 [usbcore] [ 243.149770] [<ffffffffa003da7d>] hub_port_connect_change+0xad/0x8a0 [usbcore] [ 243.149825] [<ffffffffa0043bf5>] ? usb_control_msg+0xe5/0x110 [usbcore] [ 243.149878] [<ffffffffa003e6e3>] hub_events+0x473/0x760 [usbcore] [ 243.149931] [<ffffffffa003ea05>] hub_thread+0x35/0x1d0 [usbcore] [ 243.149955] [<ffffffff81061960>] ? add_wait_queue+0x60/0x60 [ 243.150004] [<ffffffffa003e9d0>] ? hub_events+0x760/0x760 [usbcore] [ 243.150026] [<ffffffff8106133e>] kthread+0x8e/0xa0 [ 243.150047] [<ffffffff8157ec04>] kernel_thread_helper+0x4/0x10 [ 243.150068] [<ffffffff810612b0>] ? flush_kthread_work+0x120/0x120 [ 243.150088] [<ffffffff8157ec00>] ? gs_change+0xb/0xb [ 243.150101] Code: fd 41 54 53 48 83 ec 08 80 7f 1a 00 74 57 49 89 fc 31 db 90 49 8b 7c 24 20 45 31 f6 48 81 c7 10 02 00 00 e8 bc 64 f3 e0 49 89 c7 <4b> 8b 3c 37 49 83 c6 08 e8 4c a5 bd ff 49 83 fe 20 75 ed 45 30 [ 243.150257] RIP [<ffffffffa0468527>] stop_read_write_urbs+0x37/0x80 [usb_wwan] [ 243.150282] RSP <ffff880037e75b30> [ 243.150294] CR2: 0000000000000000 [ 243.177170] ---[ end trace fba433d9015ffb8c ]--- Reported-by: Dan Carpenter <[email protected]> Reported-by: Thomas Schäfer <[email protected]> Suggested-by: Alan Stern <[email protected]> Signed-off-by: Bjørn Mork <[email protected]> Signed-off-by: Greg Kroah-Hartman <[email protected]>
2012-07-16USB: qcserial: adding Sierra Wireless devicesBjørn Mork1-0/+20
The QMI mode of the Sierra Wireless MC7710 is close to a Gobi device, and also identified as one by the Windows drivers provided by Sony. The serial interfaces are the same as for any other Gobi module, but the USB interface layout is different: 0: DM/DIAG (also present in bootloader mode) 2: NMEA 3: AT-capable modem port 8: QMI/net 19: QMI/net (not always present) 20: QMI/net (not always present) Note in particular that the NMEA and AT ports are reversed compared to a Gobi 2k+ device, and that the DM port appears as a QDL port in bootloader mode using the same device ID. The Sony driver also document two new devices with standard Gobi 2k+ layout (1199:68a5, 1199:68a9) having a QDL mode (1199:68a4, 1199:68a8). Adding these as well. Lenovo Windows drivers document the USB interface layout for a few additional Sierra Wireless devices. Adding these while at it: - MC7770 (1199:901b) with standard Gobi 2k+ layout - MC7700 (0f3d:68a2) with the same layout as MC7710 - MC7750 (114f:68a2) with the same layout as MC7710 - EM7700 (1199:901c) with the same layout as MC7710 Cc: Anton Samokhvalov <[email protected]> Signed-off-by: Bjørn Mork <[email protected]> Signed-off-by: Greg Kroah-Hartman <[email protected]>

2012-05-08USB: serial: rework usb_serial_register/deregister_drivers()Greg Kroah-Hartman1-6/+1
This reworks the usb_serial_register_drivers() and usb_serial_deregister_drivers() to not need a pointer to a struct usb_driver anymore. The usb_driver structure is now created dynamically and registered and unregistered as needed. This saves lines of code in each usb-serial driver. All in-kernel users of these functions were also fixed up at this time. The pl2303 driver was tested that everything worked properly. Thanks for the idea to do this from Alan Stern.

2012-05-07usb-serial: clean up unneeded PM-related fieldsAlan Stern1-3/+0
This patch (as1551) cleans up the PM-related entries in the usb_driver structures of the various USB serial driver modules. Those entries are now filled in by the usb-serial core during driver registration, so they don't need to be initialized explicitly in the source code. The same is true of the one remaining no_dynamic_id entry. reset_resume remains a small problem, because the serial core doesn't support it. The patch ignores these entries.

In the near future we'll be attaching another driver to the QMI/net port for these devices (cdc-wdm and qmi_wwan) so make sure the qcserial driver doesn't claim them.

2010-05-20USB: qcserial: Add support for Qualcomm Gobi 2000 devicesAnssi Hannula1-17/+25
Add ids for Qualcomm Gobi 2000 QDL and Modem modes. Gobi 2000 has a single altsetting in QDL mode, so adapt code to handle that. Firmware upload protocol is also slightly different, with an additional firmware file. However, qcserial doesn't handle firmware uploading. Tested on Lenovo Thinkpad T510.

Make qcserial use the generic USB wwan code. This should result in a performance improvement. Signed-off-by: Matthew Garrett <[email protected]> Signed-off-by: Greg Kroah-Hartman <[email protected]>
2010-03-19USB: qcserial: add new device idsBernhard Rosenkraenzer1-0/+29
This patch adds various USB device IDs for Gobi 2000 devices, as found in the drivers available at https://www.codeaurora.org/wiki/GOBI_Releases Signed-off-by: Bernhard Rosenkraenzer <[email protected]> Cc: stable <[email protected]> Signed-off-by: Greg Kroah-Hartman <[email protected]>
2010-03-02USB serial: make USB device id constantNémeth Márton1-1/+1
The id_table field of the struct usb_device_id is constant in <linux/usb.h> so it is worth to make the initialization data also constant. The semantic match that finds this kind of pattern is as follows: (http://coccinelle.lip6.fr/) // <smpl> @r@ disable decl_init,const_decl_init; identifier I1, I2, x; @@ struct I1 { ... const struct I2 *x; ... }; @s@ identifier r.I1, y; identifier r.x, E; @@ struct I1 y = { .x = E, }; @c@ identifier r.I2; identifier s.E; @@ const struct I2 E[] = ... ; @depends on !c@ identifier r.I2; identifier s.E; @@ + const struct I2 E[] = ...; // </smpl> Signed-off-by: Németh Márton <[email protected]> Cc: Julia Lawall <[email protected]> Cc: [email protected] Signed-off-by: Greg Kroah-Hartman <[email protected]>
2009-04-17USB: qcserial: Add extra device IDsMatthew Garrett1-0/+21
Add a set of device IDs from the Windows drivers. These aren't complete (there's a couple of cases where a QDL device is identified without the associated modem being identified), but it's better than the current situation.

2009-03-24USB: serial: add qualcomm wireless modem driverGreg Kroah-Hartman1-0/+145
Driver originally written by Qualcomm, but rewritten by me due to the totally different coding style. Cleaned up the probe logic to make a bit more sense, this is one wierd device. They could have prevented all of this by just writing sane firmware for the modem. Cc: Tamm Liu <[email protected]> Signed-off-by: Greg Kroah-Hartman <[email protected]>
