2010-03-02USB: cxacru: check data length is not negativeSimon Arlott
When attempting to read data that is not actually an array of values, the length may be negative which causes an Oops due to a likely access off the end of the data array. This bug should not occur under normal use unless the device returns an invalid response. Signed-off-by: Simon Arlott <simon@fire.lp0.eu> Signed-off-by: Greg Kroah-Hartman <gregkh@suse.de>

2010-03-02tty: Add a new VT mode which is like VT_PROCESS but doesn't require a ↵Ari Entlich
VT_RELDISP ioctl call This new VT mode (VT_PROCESS_AUTO) does everything that VT_PROCESS does except that it doesn't wait for a VT_RELDISP ioctl before switching away from a VT with that mode. If the X server eventually uses this new mode, debugging and crash recovery should become easier. This is because even when currently in the VT of a frozen X server it would still be possible to switch out by doing SysRq-r and then CTRL-<number of a text vt>, sshing in and doing chvt <number of a text vt>, or any other method of VT switching. The general concensus on #xorg-devel seems to be that it should be safe to use this with X now that we have KMS. This also moves the VT_ACKACQ define to a more appropriate place, for clarity's sake.

2010-03-02tty: Fix the ldisc hangup raceAlan Cox
This was noticed by Matthias Urlichs and he proposed a fix. This patch does the fixing a different way to avoid introducing several new race conditions into the code. The problem case is TTY_DRIVER_RESET_TERMIOS = 0. In that case while we abort the ldisc change, the hangup processing has not cleaned up and restarted the ldisc either. We can't restart the ldisc stuff in the set_ldisc as we don't know what the hangup did and may touch stuff we shouldn't as we are no longer supposed to influence the tty at that point in case it has been re-opened before we get rescheduled. Instead do it the simple way. Always re-init the ldisc on the hangup, but use TTY_DRIVER_RESET_TERMIOS to indicate that we should force N_TTY.

In particular it marks the tty as closed on the first close() not on the last.

2010-03-02serial: synclink_gt: dropped transmit data bugfixPaul Fulghum
Fix transmit bug that could drop send data if write() called close to serial transmitter going idle after sending previous data. Bug is caused by incorrect use of device information member tx_count. Driver originally processed one data block (write call) at a time, waiting for transmit idle before sending more. tx_count recorded how much data was loaded in DMA buffers on write(), and was cleared on send completion. tx_count use was overloaded to record accumulated data from put_char() callback when transmitter was idle. A bug was introduced when transmit code was reworked to allow multiple blocks of data in the tx DMA buffers which keeps transmitter from going idle between blocks. tx_count was set to size of last block loaded, cleared when tx went idle, and monitored to know when to restart transmitter without proper synchronization. tx_count could be cleared when unsent data remained in DMA buffers and transmitter required restarting, effectively dropping unsent data. Solution: 1. tx_count now used only to track accumulated data from put_char 2. DMA buffer state tracked by direct inspection of descriptors with spinlock synchronization 3. consolidate these tasks in tx_load() : a. check for available buffer space b. load buffers c. restart DMA and or serial transmitter as needed These steps were previously duplicated in multiple places, sometimes incompletely. 4. fix use of tx_count as active transmit indicator, instead using tx_active which is meant for that purpose Signed-off-by: Paul Fulghum <paulkf@microgate.com> Cc: Alan Cox <alan@lxorguk.ukuu.org.uk> Cc: Greg KH <greg@kroah.com> Signed-off-by: Andrew Morton <akpm@linux-foundation.org> Signed-off-by: Greg Kroah-Hartman <gregkh@suse.de>

Currently we were adding ioctl cmds/structures for ocfs2 into ocfs2_fs.h which was used for define ocfs2 on-disk layout. That sounds a little bit confusing, and it may be quickly polluted espcially when growing the ocfs2_info_request ioctls afterwards(it will grow i bet). As a result, such OCFS2 IOCs do need to be placed somewhere other than ocfs2_fs.h, a separated ocfs2_ioctl.h will be added to store such ioctl structures and definitions which could also be used from userspace to invoke ioctls call.

This makes the COH 901 318 configure channel direction (to or from device) dynamically, instead of being passed in from the platform data. This was necessary in order to get the MMC/SD-card channel bidirectional (all other channels on the U300 were either RX or TX but this one was both). This also sets memcpy() alignent to even 2^2 (32bit) boundaries, which makes the memcpy() stress tests start working.

2010-03-02DMAENGINE: COH 901 318 remove irq countingLinus Walleij
This removes the pointless irq counting for the COH 901 318, as it turns out the hardware will only ever fire one IRQ for a linked list anyway. In the process also a missing spinlock was introduced.

This centralize some spread-out initialization of descriptors into one function and cleans up the error paths. Signed-off-by: Linus Walleij <linus.walleij@stericsson.com> Signed-off-by: Dan Williams <dan.j.williams@intel.com>
