Ok.
One of the classes of kernel stack content leaks[1] is exposing the
contents of prior heap or stack contents when a new process stack is
allocated. Normally, those stacks are not zeroed, and the old contents
remain in place. In the face of stack content exposure flaws, those
contents can leak to us

This patchset introduces memcg variant memory allocation functions. The
caller can explicitly pass the memcg to charge for kmem allocations.
Currently the kernel, for __GFP_ACCOUNT memory allocation requests,

A lot of memory can be consumed by the events generated for the huge or
unlimited queues if there is either no or slow listener. This can cause
system level memory pressure or OOMs. So, it's better to account the
fsnotify kmem caches to the memcg of the listener.
There are seven fsnotify kmem cach

Hi,
It seems that in at least one case[1], nla_put_string() is being used
on an NLA_STRING, which lacks a NULL terminator, which leads to
silliness when nla_put_string() uses strlen() to figure out the size:
/**
* nla_put_string - Add a string netlink attribute to a socket buffer
* @skb: socket

If there is a memory allocation error when trying to change an audit
kernel feature value, the ignored allocation error will trigger a NULL
pointer dereference oops on subsequent use of that pointer. Return
instead.

The following patches adds support for PWM based Tegra Tachometer driver
which implements PWM capture interface to analyze the PWM signal of a
electronic fan and reports it in periods and duty cycles.
Generic PWM Tachometer implemented to monitor the speed of fan in rpms
using PWM interface. RPM o
PWM Tachometer driver capture the PWM signal which is output of FAN
in general and provide the period of PWM signal which is converted to
RPM by SW.
Add Tegra Tachometer driver which implements the pwm-capture to
measure period.
