If the device is disconnected while serial_open() is executing and either try_module_get() or the device specific open function fails, the kref_put() call in the 'bailout_kref_put' label will free the memory pointed out by 'port'. The subsequent dereferences in the 'bailout_kref_put' label will be invalid. The fix is just to assure kref_put() is called after any 'port' usage. Signed-off-by: Luiz Fernando N.

It's become apparent as machines get faster that the emagic kernel firmware loaders (based on the ezusb loader) have a reset race. a 400MHz TiBook never tripped it, but a 2GHz Pentium M seems to hit it about 30% of the time. The bug is seen as a hung USB box and the kernel error: drivers/usb/misc/emi62.c: emi62_load_firmware - error loading firmware: error = -110 The patch below inserts a delay after deasserting reset to allow the box to settle before a new command is issued. This affects only device startup. Signed-off-by: Andrew Morton <akpm@osdl.org> Signed-off-by: Greg Kroah-Hartman <gregkh@suse.de>

This patch adds support for ACG Identification Technologies GmbH's HF Dual ISO Reader (an RFID tag reader) to the ftdi_sio driver's device ID table. The product ID was supplied by anotonios (anton at goto10 dot org) on the ftdi-usb-sio-devel list and subsequently verified by myself (Ian Abbott).

In kernel 2.6.16, if a mounted storage device is removed, an oops happens because ub supplies an interface device (and kobject) to the block layer, but neglects to pin it. And apparently, the block layer expects its users to pin device structures. The code in ub was broken this way for years. But the bug was exposed only by 2.6.16 when it started to call block_uevent on close, which traverses device structures (kobjects actually).

The choose_configuration() routine contains code the determine the device's power source, so that configurations requiring external power can be ruled out if the device is running on bus power. Unfortunately it turns out that some devices have errors in their config descriptors and other devices don't like the GET_DEVICE_STATUS request. Since that information wasn't used for anything else, this patch (as673) removes the code, leaving only a comment. It fixes bugzilla entry #6448.

This fixes a small regression in USB controller power usage for many OHCI controllers, notably including every non-PCI version of OHCI: on those systems, the runtime autosuspend mechanism is no longer enabled. The change moves to saner defaults. All root hubs are expected to handle remote wakeup (and hence autosuspend), although drivers for buggy silicon may override that default.

Because of the way stringify works, using an expression like 64 * 1024 for UDSL_MAX_BUF_SIZE results in 64 * 1024 turning up in the modinfo output instead of 65536. So use 65536 directly (this was the only way I found of fixing this). Signed-off-by: Duncan Sands <baldrick@free.fr> Signed-off-by: Greg Kroah-Hartman <gregkh@suse.de>

The maximum possible bandwidth for a speedtouch modem is about 7Mbaud. You can only get this by using isochronous urbs (enable_isoc=1) and altsetting 3. With the current default altsetting of 2, the modem maxes out at about 4Mbaud. So change the default altsetting to 3 when using isochronous urbs. It would be nice to base the altsetting on the detected line speed, but that's hard given the current design.

This reverts commit c8d8b837, which caused problems for the x86 build. Quoth Sam: "It was discussed on mips list but apparently the fix was bogus. I will not have time to look into it so mips can carry this local fix until we get a proper fix in mainline." Signed-off-by: Linus Torvalds <torvalds@osdl.org>

Taking the cpu hotplug semaphore in a normal events workqueue is unsafe because other tasks can wait for any workqueues with it hold. This results in a deadlock. Move the DBS timer into its own work queue which is not affected by other work queue flushes to avoid this. Has been acked by Venkatesh.

Based on analysis&patch from Robert Hentosch Observed on a Dell PE6850 with 16GB The problem occurs very early on, when the kernel allocates space for the temporary memory map called bootmap. The bootmap overlaps the EBDA region. EBDA region is not historically reserved in the e820 mapping. When the bootmap is freed it marks the EBDA region as usable. If you notice in setup.c there is already code to work around the EBDA in reserve_ebda_region(), this check however occurs after the bootmap is allocated and doesn't prevent the bootmap from using this range. AK: I redid the original patch. Thanks also to Jan Beulich for spotting some mistakes.

Playing with NMI watchdog on x86_64, I discovered that it didn't do what I expected. It always panic-ed, even when it didn't happen from interrupt context. This patch solves that problem for me. Also, in this case, do_exit() will be called with interrupts disabled, I believe. Would it be wise to also call local_irq_enable() after nmi_exit()? [Yes I added it -AK] Currently, on x86_64, any NMI watchdog timeout will cause a panic because the irq count will always be set to be in an interrupt when do_exit() is called from die_nmi(). If we add nmi_exit() to the die_nmi() call (since the nmi will never exit "normally") it seems to solve this problem. The following small program can be used to trigger the NMI watchdog to reproduce this: main () { iopl(3); for (;;) asm("cli"); } Signed-off-by: Andi Kleen <ak@suse.de> Signed-off-by: Linus Torvalds <torvalds@osdl.org>

I noticed this when poking around in this area. The oops_begin() function in x86_64 would only conditionally claim the die_lock if the call is nested, but oops_end() would always release the spinlock. This patch adds a nest count for the die lock so that the release of the lock is only done on the final oops_end().

The patch addresses a problem with ACPI SCI interrupt entry, which gets re-used, and the IRQ is assigned to another unrelated device. The patch corrects the code such that SCI IRQ is skipped and duplicate entry is avoided. Second issue came up with VIA chipset, the problem was caused by original patch assigning IRQs starting 16 and up. The VIA chipset uses 4-bit IRQ register for internal interrupt routing, and therefore cannot handle IRQ numbers assigned to its devices. The patch corrects this problem by allowing PCI IRQs below 16.

It is insane to be giving lease_init() the task of freeing the lock it is supposed to initialise, given that the lock is not guaranteed to be allocated on the stack.
