(cherry picked from commit 57b6a317bb)
This was added in 2ee9cbbd12 ("It's /proc/stat, not /proc/stats") with
no actual justification, and doesn't really make much sense on further
inspection:
* /proc/net is a symlink to "self/net", which means that /proc/net/dev
is a per-process file, and so overmounting it would only affect pid1.
Any other program that cares about /proc/net/dev would see their own
process's configuration, and unprivileged processes wouldn't be able
to see /proc/1/... data anyway.
In addition, the fact that this is a symlink means that runc will
deny the overmount because /proc/1/net/dev is not in the proc
overmount allowlist. This means that this has not worked for many
years, and probably never worked in the first place.
* /proc/self/net is already namespaced with network namespaces, so the
primary argument for allowing /proc overmounts (lxcfs-like masking of
procfs files to emulate namespacing for files that are not properly
namespaced for containers -- such as /proc/cpuinfo) is moot.
It goes without saying that lxcfs has never overmounted
/proc/self/net/... files, so the general "because lxcfs"
justification doesn't hold water either.
* The kernel has slowly been moving towards blocking overmounts in
/proc/self/. Linux 6.12 blocked overmounts for fd, fdinfo, and
map_files; future Linux versions will probably end up blocking
everything under /proc/self/.

This fixes the test case failure on Fedora.

We already have the indirect require for 1.17.3, that comes
opencontainers/cgroups[1]. That module requires that version as min, so
go can't use older versions. We can just remove the excludes.
There might be cases where people can use runc as a dependency and use
replace to override it (not sure, but probably). We were clear on what
our dependencies are, so we can sleep fine. In the unlikely case that
some project uses runc as a dependency and:
* Uses a replace for cilium v0.17.x but not the latest patch release (0.17.3 is fixed)
* they run with 32bits
* and hit this (that didn't happen always on CI)
* Ignore the changelog for 0.17.3 that mentions the buffer overflow on
32 bits platforms[2].
In that case, if we have a bug report, we can point them to the right
place. But 0.17.3 was released for some months now (most people probably
update) and 0.18.0 was released recently. I wouldn't worry about someone
hitting this in real life.
Also, the excludes directives prevent go install from working, so let's
just remove them.

Instead of setting cli.App.Version in main, let's set up
cli.VersionPrinter. This way, we only get various versions
when needed.
Note it does not change the output of runc --version.
It changes the output of runc --help though, and I think it's for the
better.

The new configuration file was initially generated by golangci-lint
migrate, when tweaked to minimize and simplify.
golangci-lint v2 switches to a new version of staticcheck which shows
much more warnings. Some of them were fixed by a few previous commits,
and the rest of them are disabled.
In particular, ST1005 had to be disabled (an attempt to fix it was made
in https://github.com/opencontainers/runc/pull/3857 but it wasn't
merged).
Also, golangci-extra was modified to include ALL staticcheck linters.

While debugging an issue involving failing mounts, I discovered that
just returning the plain mount error message when we are in the fallback
code for handling locked mounts leads to unnecessary confusion.
It also doesn't help that podman currently forcefully sets "rw" on
mounts, which means that rootless containers are likely to hit the
locked mounts issue fairly often.
So we should improve our error messages to explain why the mount is
failing in the locked flags case.

When reading mount errors, it is quite hard to make sense of mount flags
in their hex form. As this is the error path, the minor performance
impact of constructing a string is probably not worth hyper-optimising.
