Remove dependency on github.com/opencontainers/runtime-tools
The direct use was two lines in `internal/cri/nri/nri_api_linux.go` -- constructing a `generate.Generator{Config: spec}` solely to satisfy the `nrigen.UnderlyingGenerator` interface defined in `containerd/nri`. Since that interface already exists, we just need an implementation. Add `spec_generator.go` in the same package, implementing `UnderlyingGenerator` directly on `*rspec.Spec` with no external dependencies beyond `runtime-spec`.

# Changelog
|
||||
This file documents all notable changes made to this project since the initial fork
|
||||
from https://github.com/syndtr/gocapability/commit/42c35b4376354fd5.
|
||||
|
||||
The format is based on [Keep a Changelog](https://keepachangelog.com/en/1.0.0/),
|
||||
and this project adheres to [Semantic Versioning](https://semver.org/spec/v2.0.0.html).
|
||||
|
||||
## [0.4.0] - 2024-11-11
|
||||
|
||||
### Added
|
||||
* New separate API for ambient ([GetAmbient], [SetAmbient], [ResetAmbient])
|
||||
and bound ([GetBound], [DropBound]) capabilities, modelled after libcap. (#176)
|
||||
|
||||
### Fixed
|
||||
* [Apply] now returns an error if called for non-zero `pid`. Before this change,
|
||||
it could silently change some capabilities of the current process, instead of
|
||||
the one identified by the `pid`. (#168, #174)
|
||||
* Fixed tests that change capabilities to be run in a separate process. (#173)
|
||||
* Other improvements in tests. (#169, #170)
|
||||
|
||||
### Changed
|
||||
* Use raw syscalls (which are slightly faster). (#176)
|
||||
* Most tests are now limited to testing the public API of the package. (#162)
|
||||
* Simplify parsing /proc/*pid*/status, add a test case. (#162)
|
||||
* Optimize the number of syscall to set ambient capabilities in Apply
|
||||
by clearing them first; add a test case. (#163, #164)
|
||||
* Better documentation for [Apply], [NewFile], [NewFile2], [NewPid], [NewPid2]. (#175)
|
||||
|
||||
### Removed
|
||||
* `.golangci.yml` and `.codespellrc` are no longer part of the package. (#158)
|
||||
|
||||
## [0.3.0] - 2024-09-25
|
||||
|
||||
### Added
|
||||
* Added [ListKnown] and [ListSupported] functions. (#153)
|
||||
* [LastCap] is now available on non-Linux platforms (where it returns an error). (#152)
|
||||
|
||||
### Changed
|
||||
* [List] is now deprecated in favor of [ListKnown] and [ListSupported]. (#153)
|
||||
|
||||
### Fixed
|
||||
* Various documentation improvements. (#151)
|
||||
* Fix "generated code" comment. (#153)
|
||||
|
||||
## [0.2.0] - 2024-09-16
|
||||
|
||||
This is the first release after the move to a new home in
|
||||
github.com/moby/sys/capability.
|
||||
|
||||
### Fixed
|
||||
* Fixed URLs in documentation to reflect the new home.
|
||||
|
||||
## [0.1.1] - 2024-08-01
|
||||
|
||||
This is a maintenance release, fixing a few minor issues.
|
||||
|
||||
### Fixed
|
||||
* Fixed future kernel compatibility, for real this time. [#11]
|
||||
* Fixed [LastCap] to be a function. [#12]
|
||||
|
||||
## [0.1.0] - 2024-07-31
|
||||
|
||||
This is an initial release since the fork.
|
||||
|
||||
### Breaking changes
|
||||
|
||||
* The `CAP_LAST_CAP` variable is removed; users need to modify the code to
|
||||
use [LastCap] to get the value. [#6]
|
||||
* The code now requires Go >= 1.21.
|
||||
|
||||
### Added
|
||||
* `go.mod` and `go.sum` files. [#2]
|
||||
* New [LastCap] function. [#6]
|
||||
* Basic CI using GHA infra. [#8], [#9]
|
||||
* README and CHANGELOG. [#10]
|
||||
|
||||
### Fixed
|
||||
* Fixed ambient capabilities error handling in [Apply]. [#3]
|
||||
* Fixed future kernel compatibility. [#1]
|
||||
* Fixed various linter warnings. [#4], [#7]
|
||||
|
||||
### Changed
|
||||
* Go build tags changed from old-style (`+build`) to new Go 1.17+ style (`go:build`). [#2]
|
||||
|
||||
### Removed
|
||||
* Removed support for capabilities v1 and v2. [#1]
|
||||
* Removed init function so programs that use this package start faster. [#6]
|
||||
* Removed `CAP_LAST_CAP` (use [LastCap] instead). [#6]

TERMS AND CONDITIONS FOR USE, REPRODUCTION, AND DISTRIBUTION
|
||||
|
||||
1. Definitions.
|
||||
|
||||
"License" shall mean the terms and conditions for use, reproduction,
|
||||
and distribution as defined by Sections 1 through 9 of this document.
|
||||
|
||||
"Licensor" shall mean the copyright owner or entity authorized by
|
||||
the copyright owner that is granting the License.
|
||||
|
||||
"Legal Entity" shall mean the union of the acting entity and all
|
||||
other entities that control, are controlled by, or are under common
|
||||
control with that entity. For the purposes of this definition,
|
||||
"control" means (i) the power, direct or indirect, to cause the
|
||||
direction or management of such entity, whether by contract or
|
||||
otherwise, or (ii) ownership of fifty percent (50%) or more of the
|
||||
outstanding shares, or (iii) beneficial ownership of such entity.
|
||||
|
||||
"You" (or "Your") shall mean an individual or Legal Entity
|
||||
exercising permissions granted by this License.
|
||||
|
||||
"Source" form shall mean the preferred form for making modifications,
|
||||
including but not limited to software source code, documentation
|
||||
source, and configuration files.
|
||||
|
||||
"Object" form shall mean any form resulting from mechanical
|
||||
transformation or translation of a Source form, including but
|
||||
not limited to compiled object code, generated documentation,
|
||||
and conversions to other media types.
|
||||
|
||||
"Work" shall mean the work of authorship, whether in Source or
|
||||
Object form, made available under the License, as indicated by a
|
||||
copyright notice that is included in or attached to the work
|
||||
(an example is provided in the Appendix below).
|
||||
|
||||
"Derivative Works" shall mean any work, whether in Source or Object
|
||||
form, that is based on (or derived from) the Work and for which the
|
||||
editorial revisions, annotations, elaborations, or other modifications
|
||||
represent, as a whole, an original work of authorship. For the purposes
|
||||
of this License, Derivative Works shall not include works that remain
|
||||
separable from, or merely link (or bind by name) to the interfaces of,
|
||||
the Work and Derivative Works thereof.
|
||||
|
||||
"Contribution" shall mean any work of authorship, including
|
||||
the original version of the Work and any modifications or additions
|
||||
to that Work or Derivative Works thereof, that is intentionally
|
||||
submitted to Licensor for inclusion in the Work by the copyright owner
|
||||
or by an individual or Legal Entity authorized to submit on behalf of
|
||||
the copyright owner. For the purposes of this definition, "submitted"
|
||||
means any form of electronic, verbal, or written communication sent
|
||||
to the Licensor or its representatives, including but not limited to
|
||||
communication on electronic mailing lists, source code control systems,
|
||||
and issue tracking systems that are managed by, or on behalf of, the
|
||||
Licensor for the purpose of discussing and improving the Work, but
|
||||
excluding communication that is conspicuously marked or otherwise
|
||||
designated in writing by the copyright owner as "Not a Contribution."
|
||||
|
||||
"Contributor" shall mean Licensor and any individual or Legal Entity
|
||||
on behalf of whom a Contribution has been received by Licensor and
|
||||
subsequently incorporated within the Work.
|
||||
|
||||
2. Grant of Copyright License. Subject to the terms and conditions of
|
||||
this License, each Contributor hereby grants to You a perpetual,
|
||||
worldwide, non-exclusive, no-charge, royalty-free, irrevocable
|
||||
copyright license to reproduce, prepare Derivative Works of,
|
||||
publicly display, publicly perform, sublicense, and distribute the
|
||||
Work and such Derivative Works in Source or Object form.
|
||||
|
||||
3. Grant of Patent License. Subject to the terms and conditions of
|
||||
this License, each Contributor hereby grants to You a perpetual,
|
||||
worldwide, non-exclusive, no-charge, royalty-free, irrevocable
|
||||
(except as stated in this section) patent license to make, have made,
|
||||
use, offer to sell, sell, import, and otherwise transfer the Work,
|
||||
where such license applies only to those patent claims licensable
|
||||
by such Contributor that are necessarily infringed by their
|
||||
Contribution(s) alone or by combination of their Contribution(s)
|
||||
with the Work to which such Contribution(s) was submitted. If You
|
||||
institute patent litigation against any entity (including a
|
||||
cross-claim or counterclaim in a lawsuit) alleging that the Work
|
||||
or a Contribution incorporated within the Work constitutes direct
|
||||
or contributory patent infringement, then any patent licenses
|
||||
granted to You under this License for that Work shall terminate
|
||||
as of the date such litigation is filed.
|
||||
|
||||
4. Redistribution. You may reproduce and distribute copies of the
|
||||
Work or Derivative Works thereof in any medium, with or without
|
||||
modifications, and in Source or Object form, provided that You
|
||||
meet the following conditions:
|
||||
|
||||
(a) You must give any other recipients of the Work or
|
||||
Derivative Works a copy of this License; and
|
||||
|
||||
(b) You must cause any modified files to carry prominent notices
|
||||
stating that You changed the files; and
|
||||
|
||||
(c) You must retain, in the Source form of any Derivative Works
|
||||
that You distribute, all copyright, patent, trademark, and
|
||||
attribution notices from the Source form of the Work,
|
||||
excluding those notices that do not pertain to any part of
|
||||
the Derivative Works; and
|
||||
|
||||
(d) If the Work includes a "NOTICE" text file as part of its
|
||||
distribution, then any Derivative Works that You distribute must
|
||||
include a readable copy of the attribution notices contained
|
||||
within such NOTICE file, excluding those notices that do not
|
||||
pertain to any part of the Derivative Works, in at least one
|
||||
of the following places: within a NOTICE text file distributed
|
||||
as part of the Derivative Works; within the Source form or
|
||||
documentation, if provided along with the Derivative Works; or,
|
||||
within a display generated by the Derivative Works, if and
|
||||
wherever such third-party notices normally appear. The contents
|
||||
of the NOTICE file are for informational purposes only and
|
||||
do not modify the License. You may add Your own attribution
|
||||
notices within Derivative Works that You distribute, alongside
|
||||
or as an addendum to the NOTICE text from the Work, provided
|
||||
that such additional attribution notices cannot be construed
|
||||
as modifying the License.
|
||||
|
||||
You may add Your own copyright statement to Your modifications and
|
||||
may provide additional or different license terms and conditions
|
||||
for use, reproduction, or distribution of Your modifications, or
|
||||
for any such Derivative Works as a whole, provided Your use,
|
||||
reproduction, and distribution of the Work otherwise complies with
|
||||
the conditions stated in this License.
|
||||
|
||||
5. Submission of Contributions. Unless You explicitly state otherwise,
|
||||
any Contribution intentionally submitted for inclusion in the Work
|
||||
by You to the Licensor shall be under the terms and conditions of
|
||||
this License, without any additional terms or conditions.
|
||||
Notwithstanding the above, nothing herein shall supersede or modify
|
||||
the terms of any separate license agreement you may have executed
|
||||
with Licensor regarding such Contributions.
|
||||
|
||||
6. Trademarks. This License does not grant permission to use the trade
|
||||
names, trademarks, service marks, or product names of the Licensor,
|
||||
except as required for reasonable and customary use in describing the
|
||||
origin of the Work and reproducing the content of the NOTICE file.
|
||||
|
||||
7. Disclaimer of Warranty. Unless required by applicable law or
|
||||
agreed to in writing, Licensor provides the Work (and each
|
||||
Contributor provides its Contributions) on an "AS IS" BASIS,
|
||||
WITHOUT WARRANTIES OR CONDITIONS OF ANY KIND, either express or
|
||||
implied, including, without limitation, any warranties or conditions
|
||||
of TITLE, NON-INFRINGEMENT, MERCHANTABILITY, or FITNESS FOR A
|
||||
PARTICULAR PURPOSE. You are solely responsible for determining the
|
||||
appropriateness of using or redistributing the Work and assume any
|
||||
risks associated with Your exercise of permissions under this License.
|
||||
|
||||
8. Limitation of Liability. In no event and under no legal theory,
|
||||
whether in tort (including negligence), contract, or otherwise,
|
||||
unless required by applicable law (such as deliberate and grossly
|
||||
negligent acts) or agreed to in writing, shall any Contributor be
|
||||
liable to You for damages, including any direct, indirect, special,
|
||||
incidental, or consequential damages of any character arising as a
|
||||
result of this License or out of the use or inability to use the
|
||||
Work (including but not limited to damages for loss of goodwill,
|
||||
work stoppage, computer failure or malfunction, or any and all
|
||||
other commercial damages or losses), even if such Contributor
|
||||
has been advised of the possibility of such damages.
|
||||
|
||||
9. Accepting Warranty or Additional Liability. While redistributing
|
||||
the Work or Derivative Works thereof, You may choose to offer,
|
||||
and charge a fee for, acceptance of support, warranty, indemnity,
|
||||
or other liability obligations and/or rights consistent with this
|
||||
License. However, in accepting such obligations, You may act only
|
||||
on Your own behalf and on Your sole responsibility, not on behalf
|
||||
of any other Contributor, and only if You agree to indemnify,
|
||||
defend, and hold each Contributor harmless for any liability
|
||||
incurred by, or claims asserted against, such Contributor by reason
|
||||
of your accepting any such warranty or additional liability.
