Mark Ryan df7d5d7b60 unix: automatically remove container created by mkall.sh 
When GOOS=linux, mkall.sh creates a container to run linux/mkall.go.  It does not
remove this container before exiting.  Therefore each time you run mkall.sh on Linux
you end up with a new stopped container that must be manually deleted with docker rm.
This is cumbersome as it may take several runs of mkall.sh to develop and test a patch
for golang/x/sys/unix resulting in multiple containers that require manual removal.
It's also a little counterintuitive as the user doesn't invoke the docker command directly
so it's not obvious that manual cleanup is required after mkall.sh completes.  The
leftover containers aren't even that useful for debugging as they have an entrypoint
set.

Kir KolyshkinandClaude Sonnet 4.5 690c91f6ec unix: add CPUSetDynamic for systems with more than 1024 CPUs 
The existing CPUSet type is a fixed-size array limited to 1024 CPUs,
which makes it problematic to use for large systems (such as Google's
X4 instances with 1440 and 1920 vCPUs), see e.g.
https://github.com/opencontainers/runc/issues/5023.

Introduce CPUSetDynamic type and NewCPUSet constructor to support large
systems. The bit-managing routines (set/clear/isset/fill/count) are
separated and reused.

Add variants of SchedGetaffinity, SchedSetaffinity and SetMemPolicy
that accept the new type.

Amend the documentation for CPUSet.

Amend the existing TestSchedSetaffinity to:
 - test set.Fill;
 - use t.Cleanup to restore the affinity.

Add tests for new functionality (mostly a copy of existing tests).

This is an alternative to CL 727540 / CL 727541.

Benny Siegert a4199c0bfe unix: fix definition of Statvfs_t for netbsd-arm. 
This will fix the test failure on the netbsd-arm builder, but it is not
quite a real fix.

struct statvfs changed between NetBSD 9 and NetBSD 10, with notably the
"spare" member switching from [4]uint32 to [4]uint64. In addition, there
is a new member at the end with label information, if available. The
netbsd-arm builder runs on NetBSD 10, so it runs into an issue
casting the binary data into a Statvfs_t with the wrong padding.

I don't know why the issue does not happen on arm64.

It does not happen on 386 and amd64 because these builders are running
NetBSD 9 still.

The real fix would be to use the statvfs90 compat syscall on NetBSD 10
and up, but not on 9 and below.

Fixes golang/go#76097.

 - Ubuntu 25.10 as it lacks mips support;
 - Debian Stable (13) as it also lacks mips support.

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.
