2008-10-17USB: remove use of err() in drivers/usb/serialGreg Kroah-Hartman1-7/+12
err() is going away, so switch to dev_err() or printk() if it's really needed. Signed-off-by: Greg Kroah-Hartman <[email protected]>
2008-10-17USB: remove info() macro from usb/serial driversGreg Kroah-Hartman1-3/+4

2008-10-13tty: usb-serial krefsAlan Cox1-9/+15
Use kref in the USB serial drivers so that we don't free tty structures from under the URB receive handlers as has historically been the case if you were unlucky. This also gives us a framework for general tty drivers to use tty_port objects and refcount. Contains two err->dev_err changes merged together to fix clashes in the -next tree.

2008-08-13usb-serial: don't release unregistered minorsAlan Stern1-4/+3
This patch (as1121) fixes a bug in the USB serial core. When a device is unregistered, the core will give back its minors -- even if the device hasn't been assigned any! The patch reserves the highest minor value (255) to mean that no minor was assigned. It also removes some dead code and does a small style fixup.

2008-07-22usb_serial: API all changeAlan Cox1-41/+41
USB serial likes to use port->tty back pointers for the real work it does and to do so without any actual locking. Unfortunately when you consider hangup events, hangup/parallel reopen or even worse hangup followed by parallel close events the tty->port and port->tty pointers are not guaranteed to be the same as port->tty is the active tty while tty->port is the port the tty may or may not still be attached to. So rework the entire API to pass the tty struct. For console cases we need to pass both for now. This shows up multiple drivers that immediately crash with USB console some of which have been fixed in the process. Longer term we need a proper tty as console abstraction Signed-off-by: Alan Cox <[email protected]> Signed-off-by: Greg Kroah-Hartman <[email protected]> Signed-off-by: Linus Torvalds <[email protected]>

The num_interrupt_in, num_bulk_in, and other checks in the usb-serial code are just wrong, there are too many different devices out there with different numbers of endpoints.

2008-02-01USB: Prepare serial core for autosuspend.Sarah Sharp1-2/+10
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.

2008-02-01USB: usb_serial: clean tty reference in the last closeAristeu Rozanski1-2/+4
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.

2007-10-12USB: serial core should respect driver requirementsAlan Stern1-9/+22
This patch (as997) fixes a bug in the USB serial core. The core needs to pay attention to drivers' requirements regarding the number and type of endpoints a device has. At the same time, the patch changes the NUM_DONT_CARE constant (which is stored in a single-byte field) from -1 to a safer, unsigned value. It also improves the kerneldoc for several fields in the usb_serial_driver structure. Finally, the patch replaces a list_for_each() with list_for_each_entry().

2007-07-12synchronization in usb_serial_putBenny Halevy1-2/+2
I think there is a race between usb_serial_put() and usb_serial_get_by_index() (and get_free_serial()) with regards to handling the serial port refcount. usb_serial_get_by_index() gets a reference on the serial port under table_lock while return_serial releases all the returned ports from the table under the same lock. However, the table_lock is not taken around the call to kref_put, theoretically allowing to sneak in and grab a reference after kref_put has already determined that the reference count is zero (and before calling destroy_serial) causing use after free.

2006-10-02[PATCH] const struct tty_operationsJeff Dike1-1/+1
As part of an SMP cleanliness pass over UML, I consted a bunch of structures in order to not have to document their locking. One of these structures was a struct tty_operations. In order to const it in UML without introducing compiler complaints, the declaration of tty_set_operations needs to be changed, and then all of its callers need to be fixed. This patch declares all struct tty_operations in the tree as const. In all cases, they are static and used only as input to tty_set_operations. As an extra check, I ran an i386 allyesconfig build which produced no extra warnings. 53 drivers are affected. I checked the history of a bunch of them, and in most cases, there have been only a handful of maintenance changes in the last six months. serial_core.c was the busiest one that I looked at.
