There are more useful checks such as nilness that are not enabled by
default. However fieldalignment and shadow produce a lot of warnings
that are not real issues, i.e. we shadow "err" as variable all the time,
so they get disabled.

I was not able to find any external users of pkg/selinux but kept it
for now (and marked as deprecated) so we can remove it later.
PS pkg/selinux adds go:fix directives which are not (yet) recognized
by the gocheckcompilerdirectives linter, so add a temporary exception).

Apparently, prealloc got much smarter in this version, so let's disable
it for _test.go files as we're not really interested in
micro-optimizations for the test code.
The rest of its warnings is being fixed by the earlier commits.

golangci-lint v2 introduced a new command, fmt, which runs configured
formatters (see formatters in .golangci.yml).
Use this for generated files. Drop separate goimports binary.

This ended up slightly more complicated than anticipated, tin part
because golangci-lint v2 dropped support for --exclude-dirs, so
linter issues with GOOS=windows and GOOS=darwin which were previously
ignored had to be fixed now.
This is also the reason why the ./hack/golangci-lint was simplified.
In addition, it now runs linters on Linux without systemd tag set.
Tested locally with:
for OS in linux windows darwin; do GOOS=$OS ./hack/golangci-lint.sh; done
Linting for GOOS=linux
+ ./bin/golangci-lint run --build-tags=apparmor,seccomp,selinux
0 issues.
+ ./bin/golangci-lint run --build-tags=apparmor,seccomp,selinux,systemd
0 issues.
+ ./bin/golangci-lint run --build-tags=apparmor,seccomp,selinux,remote
0 issues.
Linting for GOOS=windows
+ ./bin/golangci-lint run --build-tags=remote,containers_image_openpgp
0 issues.
Linting for GOOS=darwin
+ ./bin/golangci-lint run --build-tags=remote,containers_image_openpgp

remove those that make no sense.

* importas: does nothing with empty configuration;
* loggercheck: this repo does not use any loggers it checks (kitlog,klog,logr,zap);

Instead of enabling all linters, and when disabling some of them because
we don't like them, switch to list of explicitly enabled linters. The
upside of this is we can easily upgrade golangci-lint (i.e. any new
linters won't break our CI). The downside is, we need to explicitly
enable extra linters.
To me, this is better from the maintainability perspective.
NOTE this commit does not change the configuration in any way, in other
words, the list of linters being run is the same as before. The next
commit will address this.

Many dependencies started using go 1.22 which means we have to follow in
order to update.
Disable the now depracted exportloopref linter as it was replaced by
copyloopvar as go fixed the loop copy problem in 1.22[1]
Another new chnage in go 1.22 is the for loop syntax over ints, the
intrange linter chacks for this but there a lot of loops that have to be
converted so I didn't do it here and disable th elinter for now, th eold
syntax is still fine.

When golangci-lint it will only report 3 errors fromt he same linter by
default. This is annoying when a new linter is added and you think only
3 three errors lets fix it real quick only to notice when you rerun it
there again new 3 errors and so on.
In CI and local I want to see all issues at once so I can fix them and
know how much work it is before starting to fix them.
With `max-issues-per-linter: 0` and `max-same-issues: 0` it will show
us all errors because 0 means unlimted. By default it will only show 50
per linter and 3 from the same issue.

The new version contains the ginkgolinter, which makes sure the
assertions are more helpful.
Also replace the deprecated os.SEEK_END with io.SeekEnd.
There is also a new `musttag` linter which checks if struct that are
un/marshalled all have json tags. This results in many warnings so I
disabled the check for now. We can reenable it if we think it is worth
it but for now it way to much work to fix all report problems.

Update to the latest golangci-lint version. v1.46 added new linters.
I disabled nonamedreturns and exhaustruct since they enforce a certain
code style and using them would require big changes to the code base.
The nosprintfhostport is new and I fixed one problem in the tests. While
the test itself is fine because it uses ipv4 only the linter still looks
good because the sprintf use will fail for ipv6 addresses.

The nolintlint linter does not deny the use of `//nolint`
Instead it allows us to enforce a common nolint style:
- force that a linter name must be specified
- do not add a space between `//` and `nolint`
- make sure nolint is only used when there is actually a problem

The errcheck linter makes sure that errors are always check and not
ignored by accident. It spotted a lot of unchecked errors, mostly in the
tests but also some real problem in the code.
Signed-off-by: Paul Holzinger <pholzing@redhat.com>
The linter ensures a common code style.
- use switch/case instead of else if
- use if instead of switch/case for single case statement
- add space between comment and text
- detect the use of defer with os.Exit()
- use short form var += "..." instead of var = var + "..."
- detect problems with append()
```
newSlice := append(orgSlice, val)
```
This could lead to nasty bugs because the orgSlice will be changed in
place if it has enough capacity too hold the new elements. Thus we
newSlice might not be a copy.
Of course most of the changes are just cosmetic and do not cause any
logic errors but I think it is a good idea to enforce a common style.
This should help maintainability.

golint, scopelint and interfacer are deprecated. golint is replaced by
revive. This linter is better because it will also check for our error
style: `error strings should not be capitalized or end with punctuation or a newline`
scopelint is replaced by exportloopref (already endabled)
interfacer has no replacement but I do not think this linter is
important.
