This matcher was only used internally in the containerd implementation of
the image store. Un-export it, and make it a local utility in that package
to prevent external use.
This package was introduced in 1616a09b61
(v24.0), and there are no known external consumers of this package, so there
should be no need to deprecate / alias the old location.

The names of extended attributes are not completely freeform. Attributes
are namespaced, and the kernel enforces (among other things) that only
attributes whose names are prefixed with a valid namespace are
permitted. The name of the attribute therefore needs to be known in
order to diagnose issues with lsetxattr. Include the name of the
extended attribute in the errors returned from the Lsetxattr and
Lgetxattr so users and us can more easily troubleshoot xattr-related
issues. Include the name in a separate rich-error field to provide code
handling the error enough information to determine whether or not the
failure can be ignored.

This package provided utilities to obtain the apparmor_parser version, as well
as loading a profile.
Commit e3e715666f (included in v24.0.0 through
bfffb0974e) deprecated GetVersion, as it was no
longer used, which made LoadProfile the only utility remaining in this package.
LoadProfile appears to have no external consumers, and the only use in our code
is "profiles/apparmor".
This patch moves the remaining code (LoadProfile) to profiles/apparmor as a
non-exported function, and deletes the package.

When writing a tar file with archive/tar, extended attributes in the
deprecated (tar.Header).Xattrs map take precedence over conflicting
'SCHILY.xattr' records in the (tar.Header).PAXRecords map. Update

Fix a silly bug in the implementation which had the effect of
len(h.Xattrs) blank entries being inserted in the middle of
orderedHeaders. Luckily this is not a load-bearing bug: empty headers
are ignored as the tarsum digest is computed by concatenating header
keys and values without any intervening delimiter.

The existing pkg/archive unit tests are primarily round-trip tests which
assert that pkg/archive produces tarballs which pkg/archive can unpack.
While these tests are effective at catching regressions in archiving or
unarchiving, they have a blind spot for regressions in compatibility
with the rest of the ecosystem. For example, a typo in the capabilities
extended attribute constant would result in subtly broken image layer
tarballs, but the existing tests would not catch the bug if both the
archiving and unarchiving implementations have the same typo.
Extend the test for archiving an overlay filesystem layer to assert that
the overlayfs style whiteouts (extended attributes and device files) are
transformed into AUFS-style whiteouts (magic file names).
Extend the test for archiving files with extended attributes to assert
that the extended attribute is encoded into the file's tar header in the
standard, interoperable format compatible with the rest of the
ecosystem.

This package was introduced in af59752712
as a utility package for devicemapper, which was removed in commit

Implement a function that returns an error to replace existing uses of
the IsOSSupported utility, where callers had to produce the error after
checking.
The IsOSSupported function was used in combination with images, so implementing
a utility in "image" to prevent having to import pkg/system (which contains many

When running a `docker cp` to copy files to/from a container, the
lookup of the `getent` executable happens within the container's
filesystem, so we cannot re-use the results.
Unfortunately, that also means we can't preserve the results for
any other uses of these functions, but probably the lookup should not
be "too" costly.

These tests were made parallel to speed up the execution, but this
turned out to be flaky, because they mutate some shared state.
The tests use shared `storage` variable without any synchronization.
However, adding synchronization is not enough in all cases, some tests
register the same plugin, so they can't be run in parallel to each
other.
This commit adds the synchronization around `storage` variable
modification and removes parallel from the tests where it's not enough.

This variable was only accessed from within LocalRegistry methods, but
due to being a package-level variable, tests had to deal with setting
and resetting it.
Move it to be a field scoped to the LocalRegistry. This simplifies the
tests, and to make this more transparent, also removing the "Setup()"
helper (which, wasn't marked as a t.Helper()).
