2012-01-06Merge branch 'driver-core-next' into Linux 3.2Greg Kroah-Hartman3-46/+3
This resolves the conflict in the arch/arm/mach-s3c64xx/s3c6400.c file, and it fixes the build error in the arch/x86/kernel/microcode_core.c file, that the merge did not catch. The microcode_core.c patch was provided by Stephen Rothwell <sfr@canb.auug.org.au> who was invaluable in the merge issues involved with the large sysdev removal process in the driver-core tree.

2012-01-05drivers/usb/class/cdc-acm.c: clear dangling pointerJulia Lawall1-0/+4
On some failures, the country_code field of an acm structure is freed without freeing the acm structure itself. Elsewhere, operations including memcpy and kfree are performed on the country_code field. The patch sets the country_code field to NULL when it is freed, and likewise sets the country_code_size field to 0.

2011-12-10usb: cdc-acm: Kill ACM_READY() macro completelyHavard Skinnemoen1-9/+1
The ACM_READY() macro doesn't seem to do anything useful, and it may prevent tty_wait_until_sent() from working properly when called from close. Previously, acm_tty_chars_in_buffer() returned 0 whenever acm->port.count was 0. This means close() could return before all the data has actually been written.

2011-12-10USB: cdc-acm: Fix potential deadlock (lockdep warning)Havard Skinnemoen2-138/+189
Rework the locking and lifecycle management in the cdc-acm driver. Instead of using a global mutex to prevent the 'acm' object from being freed, use the tty_port kref to keep the device alive when either the USB side or TTY side is still active. This allows us to use the global mutex purely for protecting the acm_table, while use acm->mutex to guard against disconnect during TTY port activation and shutdown. The USB-side kref is taken during port initialization in probe(), and released at the end of disconnect(). The TTY-side kref is taken in install() and released in cleanup(). On disconnect, tty_vhangup() is called instead of tty_hangup() to ensure the TTY hangup processing is completed before the USB device is taken down. The TTY open and close handlers have been gutted and replaced with tty_port_open() and tty_port_close() respectively. The driver-specific code which used to be there was spread across install(), activate() and shutdown().

2011-11-18USB: convert drivers/usb/* to use module_usb_driver()Greg Kroah-Hartman3-46/+3
This converts the drivers in drivers/usb/* to use the module_usb_driver() macro which makes the code smaller and a bit simpler. Added bonus is that it removes some unneeded kernel log messages about drivers loading and/or unloading.

2011-11-15USB: cdc-acm: Fix disconnect() vs close() raceHavard Skinnemoen1-3/+5
There's a race between the USB disconnect handler and the TTY close handler which may cause the acm object to be freed while it's still being used. This may lead to things like http://article.gmane.org/gmane.linux.usb.general/54250 and https://lkml.org/lkml/2011/5/29/64 This is the simplest fix I could come up with. Holding on to open_mutex while closing the TTY device prevents acm_disconnect() from freeing the acm object between acm->port.count drops to 0 and the TTY side of the cleanups are finalized.

2011-03-23USB: Fix 'bad dma' problem on WDM device disconnectRobert Lukassen1-1/+1
In the WDM class driver a disconnect event leads to calls to usb_free_coherent to put back two USB DMA buffers allocated earlier. The call to usb_free_coherent uses a different size parameter (desc->wMaxCommand) than the corresponding call to usb_alloc_coherent (desc->bMaxPacketSize0). When a disconnect event occurs, this leads to 'bad dma' complaints from usb core because the USB DMA buffer is being pushed back to the 'buffer-2048' pool from which it has not been allocated. This patch against the most recent linux-2.6 kernel ensures that the parameters used by usb_alloc_coherent & usb_free_coherent calls in cdc-wdm.c match.

We don't actually need this and it causes problems for internal use of this functionality. Currently there is a single use of the FILE * pointer. That is the serial core which uses it to check tty_hung_up_p. However if that is true then IO_ERROR is also already set so the check may be removed.

2010-10-15llseek: automatically add .llseek fopArnd Bergmann3-1/+4
All file_operations should get a .llseek operation so we can make nonseekable_open the default for future file operations without a .llseek pointer. The three cases that we can automatically detect are no_llseek, seq_lseek and default_llseek. For cases where we can we can automatically prove that the file offset is always ignored, we use noop_llseek, which maintains the current behavior of not returning an error from a seek. New drivers should normally not use noop_llseek but instead use no_llseek and call nonseekable_open at open time. Existing drivers can be converted to do the same when the maintainer knows for certain that no user code relies on calling seek on the device file. The generated code is often incorrectly indented and right now contains comments that clarify for each added line why a specific variant was chosen. In the version that gets submitted upstream, the comments will be gone and I will manually fix the indentation, because there does not seem to be a way to do that using coccinelle. Some amount of new code is currently sitting in linux-next that should get the same modifications, which I will do at the end of the merge window. Many thanks to Julia Lawall for helping me learn to write a semantic patch that does all this. ===== begin semantic patch ===== // This adds an llseek= method to all file operations, // as a preparation for making no_llseek the default. // // The rules are // - use no_llseek explicitly if we do nonseekable_open // - use seq_lseek for sequential files // - use default_llseek if we know we access f_pos // - use noop_llseek if we know we don't access f_pos, // but we still want to allow users to call lseek // @ open1 exists @ identifier nested_open; @@ nested_open(...) { <+... nonseekable_open(...) ...+> } @ open exists@ identifier open_f; identifier i, f; identifier open1.nested_open; @@ int open_f(struct inode *i, struct file *f) { <+...

2010-09-04USB: cdc-acm: Fixing crash when ACM probing interfaces with no endpoint ↵Toby Gray1-1/+2
descriptors. Certain USB devices, such as the Nokia X6 mobile phone, don't expose any endpoint descriptors on some of their interfaces. If the ACM driver is forced to probe all interfaces on a device the a NULL pointer dereference will occur when the ACM driver attempts to use the endpoint of the alternative settings. One way to get the ACM driver to probe all the interfaces is by using the /sys/bus/usb/drivers/cdc_acm/new_id interface. This patch checks that the endpoint pointer for the current alternate settings is non-NULL before using it.

2010-09-04USB: cdc-acm: Adding second ACM channel support for various Nokia and one ↵Toby Gray1-0/+16
Samsung phones S60 phones from Nokia and Samsung expose two ACM channels. The first is a modem with a standard AT-command interface, which is picked up correctly by CDC-ACM. The second ACM port is marked as having a vendor-specific protocol. This means that the ACM driver will not claim the second channel by default. This adds support for the second ACM channel for the following devices: Nokia E63 Nokia E75 Nokia 6760 Slide Nokia E52 Nokia E55 Nokia E72 Nokia X6 Nokia N97 Mini Nokia 5800 Xpressmusic Nokia E90 Samsung GTi8510 (INNOV8) Signed-off-by: Toby Gray <toby.gray@realvnc.com> Cc: Oliver Neukum <oliver@neukum.name> Cc: stable <stable@kernel.org> Signed-off-by: Greg Kroah-Hartman <gregkh@suse.de>
