git://git.kernel.org/pub/scm/linux/kernel/git/rostedt/linux-trace Pull tracing ring-buffer fixes from Steven Rostedt: "Hao Qin reported an integer overflow possibility with signed and unsigned numbers in the ring-buffer code. https://bugzilla.kernel.org/show_bug.cgi?id=118001 At first I did not think this was too much of an issue, because the overflow would be caught later when either too much data was allocated or it would trigger RB_WARN_ON() which shuts down the ring buffer. But looking closer into it, I found that the right settings could bypass the checks and crash the kernel. Luckily, this is only accessible by root. The first fix is to convert all the variables into long, such that we don't get into issues between 32 bit variables being assigned 64 bit ones. This fixes the RB_WARN_ON() triggering. The next fix is to get rid of a duplicate DIV_ROUND_UP() that when called twice with the right value, can cause a kernel crash. The first DIV_ROUND_UP() is to normalize the input and it is checked against the minimum allowable value. But then DIV_ROUND_UP() is called again, which can overflow due to the (a + b - 1)/b, logic. The first called upped the value, the second can overflow (with the +b part). The second call to DIV_ROUND_UP() came in via a second change a while ago and the code is cleaned up to remove it" * tag 'trace-fixes-v4.6-rc7' of git://git.kernel.org/pub/scm/linux/kernel/git/rostedt/linux-trace: ring-buffer: Prevent overflow of size in ring_buffer_resize() ring-buffer: Use long for nr_pages to avoid overflow failures
2016-05-17net_sched: close another race condition in tcf_mirred_release()WANG Cong
We saw the following extra refcount release on veth device: kernel: [7957821.463992] unregister_netdevice: waiting for mesos50284 to become free. Usage count = -1 Since we heavily use mirred action to redirect packets to veth, I think this is caused by the following race condition: CPU0: tcf_mirred_release(): (in RCU callback) struct net_device *dev = rcu_dereference_protected(m->tcfm_dev, 1); CPU1: mirred_device_event(): spin_lock_bh(&mirred_list_lock); list_for_each_entry(m, &mirred_list, tcfm_list) { if (rcu_access_pointer(m->tcfm_dev) == dev) { dev_put(dev); /* Note : no rcu grace period necessary, as * net_device are already rcu protected. */ RCU_INIT_POINTER(m->tcfm_dev, NULL); } } spin_unlock_bh(&mirred_list_lock); CPU0: tcf_mirred_release(): spin_lock_bh(&mirred_list_lock); list_del(&m->tcfm_list); spin_unlock_bh(&mirred_list_lock); if (dev) // <======== Stil refers to the old m->tcfm_dev dev_put(dev); // <======== dev_put() is called on it again The action init code path is good because it is impossible to modify an action that is being removed. So, fix this by moving everything under the spinlock.

2016-05-17ravb: Add missing free_irq() calls to ravb_close()Geert Uytterhoeven
When reopening the network device on ra7795/salvator-x, e.g. after a DHCP timeout: IP-Config: Reopening network devices... genirq: Flags mismatch irq 139. 00000000 (eth0:ch0:rx_be) vs. 00000000 (ravb e6800000.ethernet eth0: cannot request IRQ eth0:ch0:rx_be IP-Config: Failed to open eth0 IP-Config: No network devices available The "mismatch" is due to requesting an IRQ that is already in use, while IRQF_PROBE_SHARED wasn't set.

The mulitiline code for timer initialization is now replaced with function setup_timer. Also, quoting the mod_timer() function comment: -> mod_timer() is a more efficient way to update the expire field of an active timer (if the timer is inactive it will be activated).

2016-05-17mmc: block: Pause re-tuning while switched to the RPMB partitionAdrian Hunter
Re-tuning is not possible when switched to the RPMB partition. However re-tuning should not be needed if re-tuning is done immediately before switching, a small set of operations is done, and then we immediately switch back to the main partition. A previous patch ensured that we immediately switch back to the main partition. This patch uses the new facility to "pause" re-tuning before switching to the RPMB partition, and to "unpause" it after switching from the RPMB partition.

2016-05-17mmc: core: Add a facility to "pause" re-tuningAdrian Hunter
Re-tuning is not possible when switched to the RPMB partition. However re-tuning should not be needed if re-tuning is done immediately before switching, a small set of operations is done, and then we immediately switch back to the main partition. To ensure that re-tuning can't be done for a short while, add a facility to "pause" re-tuning. The existing facility to hold / release re-tuning is used but it also flags re-tuning as needed to cause re-tuning before the next command (which will be the switch to RPMB). We also need to "unpause" in the recovery path, which is catered for by adding it to mmc_retune_disable().

During sensor's initialization it tries to enable IRQ, the driver will call thermal_zone_of_sensor_register() to bind sensors and read sensor's temperature. But at this moment the flag "data->irq_enabled" has been not initialized as correct state, so it finally introduces the function enabled_irq() to be called twice. In essentially this is caused by the flag "data->irq_enabled" is inconsistent with real hardware IRQ enabling state. So this patch is to fix this issue, firstly init "irq_enabled" flag before binding sensors to thermal zone. Also change to use the function irq_get_irqchip_state() to read back real interrupt line state. Signed-off-by: Leo Yan <leo.yan@linaro.org> Signed-off-by: Eduardo Valentin <edubezval@gmail.com>

It allows the thermal sensor driver can register any number sensors at initialization phase, and fix up code for other related code to skip related sensor's accessing if the sensor has not been enabled in initialization phase.

2016-05-17thermal: tegra: get rid of PDIV/HOTSPOT hackWei Ni
Get rid of T124-specific PDIV/HOTSPOT hack. tegra-soctherm.c contained a hack to set the SENSOR_PDIV and SENSOR_HOTSPOT_OFFSET registers - it just did two writes of T124-specific opaque values. Convert these into a form that can be substituted on a per-chip basis, and into structure fields that have at least some independent meaning.

2016-05-17thermal: tegra: combine sensor group-related dataWei Ni
Combine sensor group-related data structures into struct tegra_tsensor_group. This provides a single location for sensor group data storage. More sensor group data will be added in subsequent patches. Signed-off-by: Wei Ni <wni@nvidia.com> Signed-off-by: Eduardo Valentin <edubezval@gmail.com>
2016-05-17thermal: tegra: move tegra thermal files into tegra directoryWei Ni
Move Tegra soctherm driver to tegra directory, it's easy to maintain and add more new function support for Tegra platforms. This will also help to split soctherm driver into common parts and chip specific data related parts. Signed-off-by: Wei Ni <wni@nvidia.com> Signed-off-by: Eduardo Valentin <edubezval@gmail.com>
2016-05-17thermal: convert ti-thermal to use devm_thermal_zone_of_sensor_registerEduardo Valentin
This changes the driver to use the devm_ version of thermal_zone_of_sensor_register and cleans up the local points and unregister calls.
