For as long as I've known about it, the USBDEVFS_CONNECT ioctl hasn't done what it's supposed to. The current code reprobes _all_ the unbound USB interfaces; this patch (as1021) makes it reprobe only the interface for which it was called.

The OHCI driver's IRQ handler, while processing a WDH interrupt, masks and unmasks it. I believe this is both broken (the write may still be posted during the donelist processing it's trying to safeguard) and useless as this IRQ may not be reissued until it's acked (unless this legacy code is an uncommented workaround for some chip erratum).

This patch (as1017) makes dummy_hcd behave more like the other USB peripheral controller drivers by no longer registering its gadget driver on the platform bus. Doing that has always been a mistake, since a usb_gadget_driver isn't a platform_driver. Instead the gadget driver is left unregistered in sysfs.

I'm having problem with oopses when rebooting, if I modprobe g_serial and rmmod g_serial and do a reboot I get an oops in device_shutdown(). The reason seems to be that usb_gadget_unregister_driver() doesn't do enough cleanup. With this at91_udc patch I don't get the oops.

Claim the interface for a USB to serial converter when the tty is open, and release the interface when the tty is closed. If a driver doesn't provide a resume function, use the generic resume instead. Make sure the generic resume function does not submit the URBs if we're coming back from autosuspend. On autoresume, we know that the open function will be called next, which will attempt to submit the URBs. If we submit them in the resume function, the open will fail. This works for: - autosuspend - suspending with the tty open or closed - hibernate with the tty closed A hibernate (or a suspend that causes the USB subsystem to lose power) has issues. If you have the tty open when you hibernate, a new tty will be created when the device re-enumerates during resume.

This patch (as1012b) makes the ksuspend_usbd kernel thread non-freezable. Since the PM core has been changed to lock all devices during a system sleep, the thread no longer needs to be frozen. It won't interfere with a system sleep because before trying to resume a root hub device, it acquires the device's lock.

The usb serial method set_termios() is called for the first time from open() method in order to set up the termios structure with the default device's settings, ignoring the current settings. Once it's initialized, the next set_termios() calls will update the device with the tty->termios settings. Currently USB serial console code calls the driver open() method without a tty and after that will allocate a fake tty and termios so the command line arguments can be applied to the device (console=ttyUSB0,115200,...). This makes the driver overwrite the termios with the default settings and not applying the command line options. This patch changes usb_console_setup() to allocate the fake tty and termios before the open() method is called.

由 Aristeu Rozanski 提交于
When a usb serial adapter is used as console, the usb serial console driver bumps the open_count on the port struct used but doesn't attach a real tty to it (only a fake one temporaly). If this port is opened later using the regular character device interface, the open method won't initialize the port, which is the expected, and will receive a brand new tty struct created by tty layer, which will be stored in port->tty. When the last close is issued, open_count won't be 0 because of the console usage and the port->tty will still contain the old tty value. This is the last ttyUSB<n> close so the allocated tty will be freed by the tty layer. The usb_serial and usb_serial_port are still in use by the console, so port_free() won't be called (serial_close() -> usb_serial_put() -> destroy_serial() -> port_free()), so the scheduled work (port->work, usb_serial_port_work()) will still run. And usb_serial_port_work() does: (...) tty = port->tty; if (!tty) return; tty_wakeup(tty); which causes (manually copied): Faulting instruction address: 0x6b6b6b68 Oops: Kernel access of bad area, sig: 11 [#1] PREEMPT PowerMac Modules linked in: binfmt_misc ipv6 nfs lockd nfs_acl sunrpc dm_snapshot dm_mirror dm_mod hfsplus uinput ams input_polldev genrtc cpufreq_powersave i2c_powermac therm_adt746x snd_aoa_codec_tas snd_aoa_fabric_layout snd_aoa joydev snd_aoa_i2sbus snd_pcm_oss snd_mixer_oss snd_pcm snd_timer snd_page_alloc pmac_zilog serial_core evdev ide_cd cdrom snd appletouch soundcore snd_aoa_soundbus bcm43xx firmware_class usbhid ieee80211softmac ff_memless firewire_ohci firewire_core ieee80211 ieee80211_crypt crc_itu_t sungem sungem_phy uninorth_agp agpart ssb NIP: 6b6b6b68 LR: c01b2108 CTR: 6b6b6b6b REGS: c106de80 TRAP: 0400 Not tainted (2.6.24-rc2) MSR: 40009032 <EE,ME,IR,DR> CR: 82004024 XER: 00000000 TASK = c106b4c0[5] 'events/0' THREAD: c106c000 GPR00: 6b6b6b6b c106df30 c106b4c0 c2d613a0 00009032 00000001 00001a00 00000001 GPR08: 00000008 00000000 00000000 c106c000 42004028 00000000 016ffbe0 0171a724 GPR16: 016ffcf4 00240e24 00240e70 016fee68 016ff9a4 c03046c4 c0327f50 c03046fc GPR24: c106b6b9 c106b4c0 c101d610 c106c000 c02160fc c1eac1dc c2d613ac c2d613a0 NIP [6b6b6b68] 0x6b6b6b68 LR [c01b2108] tty_wakeup+0x6c/0x9c Call Trace: [c106df30] [c01b20e8] tty_wakeup+0x4c/0x9c (unreliable) [c106df40] [c0216138] usb_serial_port_work+0x3c/0x78 [c106df50] [c00432e8] run_workqueue+0xc4/0x15c [c106df90] [c0043798] worker_thread+0xa0/0x124 [c106dfd0] [c0048224] kthread+0x48/0x84 [c106dff0] [c00129bc] kernel_thread+0x44/0x60 Instruction dump: XXXXXXXX XXXXXXXX XXXXXXXX XXXXXXXX XXXXXXXX XXXXXXXX XXXXXXXX XXXXXXXX XXXXXXXX XXXXXXXX XXXXXXXX XXXXXXXX XXXXXXXX XXXXXXXX XXXXXXXX XXXXXXXX Slab corruption: size-2048 start=c2d613a0, len=2048 Redzone: 0x9f911029d74e35b/0x9f911029d74e35b.

This patch (as1011) adds a #define for the newly-created Lockable (i.e., password-protected) subclass 0x07 for USB mass-storage devices. The private ISD200 entry (which had been mapped to subclass 0x07) is moved to 0xf0, which is unlikely to conflict with any official subclass designation. The US_SC_MIN and US_SC_MAX constants aren't used anywhere, so the patch removes them.
