The function jbd2_journal_write_metadata_buffer() calls jbd_unlock_bh_state(bh_in) too early; this could potentially allow another thread to call get_write_access on the buffer head, modify the data, and dirty it, and allowing the wrong data to be written into the journal. Fortunately, if we lose this race, the only time this will actually cause filesystem corruption is if there is a system crash or other unclean shutdown of the system before the next commit can take place.

We found a problem with buffer head reference leaks when using an ext4 partition without a journal. In particular, calls to ext4_forget() would not to a brelse() on the input buffer head, which will cause pages they belong to to not be reclaimable. Further investigation showed that all places where ext4_journal_forget() and ext4_journal_revoke() are called are subject to the same problem. The patch below changes __ext4_journal_forget/__ext4_journal_revoke to do an explicit release of the buffer head when the journal handle isn't valid.

This patch (as1262) fixes a bug in usbfs: It refuses to accept zero-length transfers, and it insists that the buffer pointer be valid even if there is no data being transferred.

This patch (as1264) removes a bunch of unnecessary and erroneous stuff from the option USB-serial driver. Clearly there's no need to verify that the device pointer stored in the URBs is right or to store the same pointer over again. After all, the pointer can't change once it has been set up. There's also no need to call usb_clear_halt for the IN endpoint multiple times -- in fact, doing so is an error since every time after the first there will be active URBs queued for that endpoint. Since the Clear-Halts don't appear to be needed at all, the patch simply removes them. Signed-off-by: NAlan Stern <stern@rowland.harvard.edu> Signed-off-by: NGreg Kroah-Hartman <gregkh@suse.de>

This patch (as1265) removes an erroneous call to usb_clear_halt from the cypress_m8 driver. The call isn't valid because it is made from interrupt context whereas usb_clear_halt is a blocking routine. Presumably the code has never been executed; if it did it would cause an oops.

commit b7af0bb2 ("USB: allow malformed LANGID descriptors") broke support for devices without string descriptor support. Reporting string descriptors is optional to USB devices, and a device lets us know it can't deal with strings by responding to the LANGID request with a STALL token. The kernel handled that correctly before b7af0bb2 came in, but failed hard if the LANGID was reported but broken. More than that, if a device was not able to provide string descriptors, the LANGID was retrieved over and over again at each string read request. This patch changes the behaviour so that a) the LANGID is only queried once b) devices which can't handle string requests are not asked again c) devices with malformed LANGID values have a sane fallback to 0x0409 Signed-off-by: NDaniel Mack <daniel@caiaq.de> Acked-by: NAlan Stern <stern@rowland.harvard.edu> Cc: stable <stable@kernel.org> Signed-off-by: NGreg Kroah-Hartman <gregkh@suse.de>

It enhances the driver for FTDI-based USB serial adapters to recognize and support Northern Digital Inc (NDI) measurement equipment. NDI has been providing this patch for various kernel flavors for several years and we would like to see these changes built in to the driver so that our equipement works without the need for customers to patch the kernel themselves. The patch makes small modifications to 2 files: ./drivers/usb/serial/ftdi_sio.c and ./drivers/usb/serial/ftdi_sio.h. It accomplishes 3 things: 1. Define the VID and PIDs to allow the driver to recognize the NDI devices. 2. Map the 19200 baud rate setting to our higher baud rate of 1.2Mb We would have chosen to map 38400 to the higher rate, similar to what several other vendors have done, but some of our legacy customers actually use 38400, therefore we remap 19200 to the higher rate. 3. We set the default transmit latency in the FTDI chip to 1ms for our devices. Our devices are typically polled at 60Hz and the default ftdi latency seriously affects turn-around time and results in missed data frames. We have created a modprobe option that allows this setting to be increased. This has proven necessary particularly in some virtualized environments. Signed-off-by: NMartin P.

The commit 335f8514 introduced a regression which stopped usb consoles from working correctly as a kernel boot console as well as interactive login device. The addition of the serial_close() which in turn calls tty_port_close_start() will change the reference count of port.count and warn about it. The usb console code had previously incremented the port.count to indicate it was making use of the device as a console and the forced change causes a double open on the usb device which leads to a non obvious kernel oops later on when the tty is freed. To fix the problem instead make use of port->console to track if the port is in fact an active console port to avoid double initialization of the usb serial device. The port.count is incremented and decremented only with in the scope of usb_console_setup() for the purpose of the low level driver initialization.

This patch (as1257) revises the way ehci-hcd detects STALLs. The logic is a little peculiar because there's no hardware status bit specifically meant to indicate a STALL. You just have to guess that a STALL was received if the BABBLE bit (which is fatal) isn't set and the transfer stopped before all its retries were used up. The existing code doesn't do this properly, because it tests for MMF (Missed MicroFrame) and DBE (Data Buffer Error) before testing the retry counter. Thus, if a transaction gets either MMF or DBE the corresponding flag is set and the transaction is retried. If the second attempt receives a STALL then -EPIPE is the correct return value. But the existing code would see the MMF or DBE flag instead and return -EPROTO, -ENOSR, or -ECOMM.

This patch (as1255) updates the interface for calling usb_hub_clear_tt_buffer(). Even the name of the function is changed! When an async URB (i.e., Control or Bulk) going through a high-speed hub to a non-high-speed device is cancelled or fails, the hub's Transaction Translator buffer may be left busy still trying to complete the transaction. The buffer has to be cleared; that's what usb_hub_clear_tt_buffer() does. It isn't safe to send any more URBs to the same endpoint until the TT buffer is fully clear. Therefore the HCD needs to be told when the Clear-TT-Buffer request has finished. This patch adds a callback method to struct hc_driver for that purpose, and makes the hub driver invoke the callback at the proper time. The patch also changes a couple of names; "hub_tt_kevent" and "tt.kevent" now look rather antiquated.
