Aleksa Sarai 033906b9f0 unix: add (*CPUSet).Fill helper to enable all CPUs 
Some programs (such as container runtimes) want to reset their CPU
affinity if they are spawned by processes with a particular CPU
affinity. Container runtimes didn't really have to deal with this issue
until Linux 6.2 when the cpuset cgroup was changed to no longer
auto-reset CPU affinity in this case.

A naive approach to resetting your CPU affinity would be to get the
number of CPUs by looking at "/proc/stat" or "/sys/devices/system/cpu"
(note that runtime.NumCPU() actually returns the CPU affinity of the
process at startup time, which isn't useful for this purpose) and then
asking for all of those CPUs.

However, sched_setaffinity(2) will silently ignore any CPU bits set in
the provided CPUSet if they do not exist or are not enabled in the
cpuset cgroup of the process. This means that you can reset your CPU
affinity by just setting every CPU bit in CPUSet and passing it to
sched_setaffinity(2).

Unfortunately, setting every CPU bit in CPUSet with (*CPUSet).Set() is
very inefficient. If it were possible to just memset(0xFF) the CPUSet
array, users would be able to reset their CPU affinity even more
cheaply. However, Go doesn't have a memset primitive that can be used in
that way.

Obvious solutions like setting the array elements of CPUSet to (^0) do
not work because CPUSet is an array of a private newtype and so the
compiler complains if you try to use a constant like (^0) without a
cast (and we cannot use a cast because the type is private):

    cannot use ^0 (untyped int constant -1) as
    "golang.org/x/sys/unix".cpuMask value in assignment (overflows)

The only real alternative is to do something quite hacky like:

    cpuset := unix.CPUSet{}
    for i := range cpuset {
        cpuset[i]-- // underflow to 0xFF..FF
    }

... which is the solution we use in runc.

It would be much nicer to have a helper that does this memset for us in
a less hacky way, since resetting CPU affinity seems like a fairly
common operation.

Ref: Linux kernel commit da019032819a ("sched: Enforce user requested affinity")
Fixes golang/go#75186

thepudds 6a85559a3f windows: fix dangling pointers in (*SECURITY_DESCRIPTOR).ToAbsolute 
Prior to this CL, a byte slice was allocated via make to use as the
absoluteSD argument passed to the Windows API MakeAbsoluteSD.

MakeAbsoluteSD then sets pointers outside the view of the GC, including
pointers within absoluteSD that point to other chunks of memory
we pass into MakeAbsoluteSD.

CL 653856 recently allowed more make results to be stack allocated,
which worsened the problems here and made it easier for those
pointers in absoluteSD to become dangling pointers, though the
core problems here existed before.

This CL instead allocates absoluteSD as a proper SECURITY_DESCRIPTOR
struct so that the GC can be aware of its pointers. We also verify the
pointers are as we expect, and then set them explicitly
in view of the GC.

Douglas Danger Manley 1b2bd6bb49 windows: replace all StringToUTF16 calls with UTF16FromString 
`StringToUTF16` is deprecated and will panic if given an "invalid"
string (in particular, one that has a null byte in it).  The replacement
function is `UTF16FromString`, and it returns an error if there was
a problem.

This change replaces all uses of `StringToUTF16` with `UTF16FromString`.
The `service` struct now no longer stores a `string` name but rather
a `*uint16` pointer to the name.

It should not be possible to panic due to UTF16 string conversion
at this point.

Fixes golang/go#73006
