2011-10-22ARM: 7136/1: pl330: Fix a race conditionJavi Merino
If two requests have been submitted and one of them is running, if you call pl330_chan_ctrl(ch_id, PL330_OP_START), there's a window of time between the spin_lock_irqsave() and the _state() check in which the running transaction may finish. In that case, we don't receive the interrupt (because they are disabled), but _start() sees that the DMA is stopped, so it starts it. The problem is that it sends the transaction that has just finished again, because pl330_update() hasn't mark it as done yet. This patch fixes this race condition by not calling _start() if the DMA is already executing transactions. When interrupts are reenabled, pl330_update() will call _start().

2011-10-22TOMOYO: Fix incomplete read after seek.Tetsuo Handa
Commit f23571e8 "TOMOYO: Copy directly to userspace buffer." introduced tomoyo_flush() that flushes data to be read as soon as possible. tomoyo_select_domain() (which is called by write()) enqueues data which meant to be read by next read(), but previous read()'s read buffer's size was not cleared. As a result, since 2.6.36, sequence like char *cp = "select global-pid=1\n"; read(fd, buf1, sizeof(buf1)); write(fd, cp, strlen(cp)); read(fd, buf2, sizeof(buf2)); causes enqueued data to be flushed to buf1 rather than buf2. Fix this bug by clearing read buffer's size upon write() request. Signed-off-by: Tetsuo Handa <penguin-kernel@I-love.SAKURA.ne.jp> Signed-off-by: James Morris <jmorris@namei.org>

Update the documentation about the interaction between the suspend (S3) call path and the CPU hotplug infrastructure. This patch focusses only on the activities of the freezer, cpu hotplug and the notifications involved. It outlines how regular CPU hotplug differs from the way it is invoked during suspend and also tries to explain the locking involved. In addition to that, it discusses the issue of microcode update during CPU hotplug operations. Signed-off-by: Srivatsa S. Bhat <srivatsa.bhat@linux.vnet.ibm.com> Signed-off-by: Rafael J.

2011-10-22ARM: mach-shmobile: sh7372 A4R support (v4)Magnus Damm
This change adds support for the sh7372 A4R power domain. The sh7372 A4R hardware power domain contains the SH CPU Core and a set of I/O devices including multimedia accelerators and I2C controllers. One special case about A4R is the INTCS interrupt controller that needs to be saved and restored to keep working as expected. Also the LCDC hardware blocks are in a different hardware power domain but have their IRQs routed only through INTCS. So as long as LCDCs are active we cannot power down INTCS because that would risk losing interrupts. Signed-off-by: Magnus Damm <damm@opensource.se> Signed-off-by: Rafael J. Wysocki <rjw@sisk.pl>
2011-10-22ARM: mach-shmobile: sh7372 A3SP support (v4)Magnus Damm
This change adds support for the sh7372 A3SP power domain. The sh7372 A3SP hardware power domain contains a wide range of I/O devices. The list of I/O devices include SCIF serial ports, DMA Engine hardware, SD and MMC controller hardware, USB controllers and I2C master controllers. This patch adds the A3SP low level code which powers the hardware power domain on and off. It also ties in platform devices to the pm domain support code. It is worth noting that the serial console is hooked up to SCIFA0 on most sh7372 boards, and the SCIFA0 port is included in the A3SP hardware power domain. For this reason we cannot output debug messages from the low level power control code in the case of A3SP. QoS support is needed in drivers before we can enable the A3SP power control on the fly.

2011-10-22PM / Sleep: Mark devices involved in wakeup signaling during suspendRafael J. Wysocki
The generic PM domains code in drivers/base/power/domain.c has to avoid powering off domains that provide power to wakeup devices during system suspend. Currently, however, this only works for wakeup devices directly belonging to the given domain and not for their children (or the children of their children and so on). Thus, if there's a wakeup device whose parent belongs to a power domain handled by the generic PM domains code, the domain will be powered off during system suspend preventing the device from signaling wakeup. To address this problem introduce a device flag, power.wakeup_path, that will be set during system suspend for all wakeup devices, their parents, the parents of their parents and so on. This way, all wakeup paths in the device hierarchy will be marked and the generic PM domains code will only need to avoid powering off domains containing devices whose power.wakeup_path is set.

2011-10-21crypto: ghash - Avoid null pointer dereference if no key is setNick Bowler
The ghash_update function passes a pointer to gf128mul_4k_lle which will be NULL if ghash_setkey is not called or if the most recent call to ghash_setkey failed to allocate memory. This causes an oops. Fix this up by returning an error code in the null case. This is trivially triggered from unprivileged userspace through the AF_ALG interface by simply writing to the socket without setting a key. The ghash_final function has a similar issue, but triggering it requires a memory allocation failure in ghash_setkey _after_ at least one successful call to ghash_update.

2011-10-21tcp: add const qualifiers where possibleEric Dumazet
Adding const qualifiers to pointers can ease code review, and spot some bugs. It might allow compiler to optimize code further. For example, is it legal to temporary write a null cksum into tcphdr in tcp_md5_hash_header() ? I am afraid a sniffer could catch the temporary null value...

2011-10-21HID: hid-magicmouse: Magic Trackpad has 1 button, not 2Daniel van Vugt
hid-magicmouse was advertising the Apple Magic Trackpad as having 2 buttons (left and right) when it actually only has 1 button. Advertising multiple buttons makes Xorg disable all button 2 and 3 emulation (using multi-finger clicks). So Xorg users don't get working right/middle-click emulation out of the box. This patch makes hid-magicmouse correctly only report one real button for Magic Trackpad, which in turn makes Xorg enable multi-finger click support to emulate right/middle buttons.

2011-10-21dev: use name hash for dev_seq_opsMihai Maruseac
Instead of using the dev->next chain and trying to resync at each call to dev_seq_start, use the name hash, keeping the bucket and the offset in seq->private field.

2011-10-21macvtap: Fix the minor device number allocationEric W. Biederman
On systems that create and delete lots of dynamic devices the 31bit linux ifindex fails to fit in the 16bit macvtap minor, resulting in unusable macvtap devices. I have systems running automated tests that that hit this condition in just a few days. Use a linux idr allocator to track which mavtap minor numbers are available and and to track the association between macvtap minor numbers and macvtap network devices. Remove the unnecessary unneccessary check to see if the network device we have found is indeed a macvtap device. With macvtap specific data structures it is impossible to find any other kind of networking device. Increase the macvtap minor range from 65536 to the full 20 bits that is supported by linux device numbers. It doesn't solve the original problem but there is no penalty for a larger minor device range. Signed-off-by: Eric W. Biederman <ebiederm@xmission.com> Signed-off-by: David S.

2011-10-21macvtap: Rewrite macvtap_newlink so the error handling works.Eric W. Biederman
Place macvlan_common_newlink at the end of macvtap_newlink because failing in newlink after registering your network device is not supported. Move device_create into a netdevice creation notifier. The network device notifier is the only hook that is called after the network device has been registered with the device layer and before register_network_device returns success.

2011-10-21macvtap: Fix macvtap_open races in the zero copy enable code.Eric W. Biederman
To see if it is appropriate to enable the macvtap zero copy feature don't test the lowerdev network device flags. Instead test the macvtap network device flags which are a direct copy of the lowerdev flags. This is important because nothing holds a reference to lowerdev and on a very bad day we lowerdev could be a pointer to stale memory. Signed-off-by: Eric W.

2011-10-21macvtap: Close a race between macvtap_open and macvtap_dellink.Eric W. Biederman
There is a small window in macvtap_open between looking up a networking device and calling macvtap_set_queue in which macvtap_del_queues called from macvtap_dellink. After calling macvtap_del_queues it is totally incorrect to allow macvtap_set_queue to proceed so prevent success by reporting that all of the available queues are in use. Signed-off-by: Eric W.
