Want to contribute? Great! First, read this page (including the small print at the end).
2+
3+
### Before you contribute
4+
Before we can use your code, you must sign the
5+
[Google Individual Contributor License Agreement](https://cla.developers.google.com/about/google-individual)
6+
(CLA), which you can do online. The CLA is necessary mainly because you own the
7+
copyright to your changes, even after your contribution becomes part of our
8+
codebase, so we need your permission to use and distribute your code. We also
9+
need to be sure of various other things—for instance that you'll tell us if you
10+
know that your code infringes on other people's patents. You don't have to sign
11+
the CLA until after you've submitted your code for review and a member has
12+
approved it, but you must do it before we can put your code into our codebase.
13+
Before you start working on a larger contribution, you should get in touch with
14+
us first through the issue tracker with your idea so that we can help out and
15+
possibly guide you. Coordinating up front makes it much easier to avoid
16+
frustration later on.
17+
18+
### Code reviews
19+
All submissions, including submissions by project members, require review. We
20+
use Github pull requests for this purpose.
21+
22+
### The small print
23+
Contributions made by corporations are covered by a different agreement than
24+
the one above, the
25+
[Software Grant and Corporate Contributor License Agreement](https://cla.developers.google.com/about/google-corporate).

104+
excluding those notices that do not pertain to any part of
105+
the Derivative Works; and
106+
107+
(d) If the Work includes a "NOTICE" text file as part of its
108+
distribution, then any Derivative Works that You distribute must
109+
include a readable copy of the attribution notices contained
110+
within such NOTICE file, excluding those notices that do not
111+
pertain to any part of the Derivative Works, in at least one
112+
of the following places: within a NOTICE text file distributed
113+
as part of the Derivative Works; within the Source form or
114+
documentation, if provided along with the Derivative Works; or,
115+
within a display generated by the Derivative Works, if and
116+
wherever such third-party notices normally appear. The contents
117+
of the NOTICE file are for informational purposes only and
118+
do not modify the License. You may add Your own attribution
119+
notices within Derivative Works that You distribute, alongside
120+
or as an addendum to the NOTICE text from the Work, provided
121+
that such additional attribution notices cannot be construed
122+
as modifying the License.
123+
124+
You may add Your own copyright statement to Your modifications and
125+
may provide additional or different license terms and conditions
126+
for use, reproduction, or distribution of Your modifications, or
127+
for any such Derivative Works as a whole, provided Your use,
128+
reproduction, and distribution of the Work otherwise complies with
129+
the conditions stated in this License.
130+
131+
5. Submission of Contributions. Unless You explicitly state otherwise,
132+
any Contribution intentionally submitted for inclusion in the Work
133+
by You to the Licensor shall be under the terms and conditions of
134+
this License, without any additional terms or conditions.
135+
Notwithstanding the above, nothing herein shall supersede or modify
136+
the terms of any separate license agreement you may have executed
137+
with Licensor regarding such Contributions.
138+
139+
6. Trademarks. This License does not grant permission to use the trade
140+
names, trademarks, service marks, or product names of the Licensor,
141+
except as required for reasonable and customary use in describing the
142+
origin of the Work and reproducing the content of the NOTICE file.
143+
144+
7. Disclaimer of Warranty. Unless required by applicable law or
145+
agreed to in writing, Licensor provides the Work (and each
146+
Contributor provides its Contributions) on an "AS IS" BASIS,
147+
WITHOUT WARRANTIES OR CONDITIONS OF ANY KIND, either express or
148+
implied, including, without limitation, any warranties or conditions
149+
of TITLE, NON-INFRINGEMENT, MERCHANTABILITY, or FITNESS FOR A
150+
PARTICULAR PURPOSE. You are solely responsible for determining the
151+
appropriateness of using or redistributing the Work and assume any
152+
risks associated with Your exercise of permissions under this License.
153+
154+
8. Limitation of Liability. In no event and under no legal theory,
155+
whether in tort (including negligence), contract, or otherwise,
156+
unless required by applicable law (such as deliberate and grossly
157+
negligent acts) or agreed to in writing, shall any Contributor be
158+
liable to You for damages, including any direct, indirect, special,
159+
incidental, or consequential damages of any character arising as a
160+
result of this License or out of the use or inability to use the
161+
Work (including but not limited to damages for loss of goodwill,
162+
work stoppage, computer failure or malfunction, or any and all
163+
other commercial damages or losses), even if such Contributor
164+
has been advised of the possibility of such damages.
165+
166+
9. Accepting Warranty or Additional Liability. While redistributing
167+
the Work or Derivative Works thereof, You may choose to offer,
168+
and charge a fee for, acceptance of support, warranty, indemnity,
169+
or other liability obligations and/or rights consistent with this
170+
License. However, in accepting such obligations, You may act only
171+
on Your own behalf and on Your sole responsibility, not on behalf
172+
of any other Contributor, and only if You agree to indemnify,
173+
defend, and hold each Contributor harmless for any liability
174+
incurred by, or claims asserted against, such Contributor by reason
175+
of your accepting any such warranty or additional liability.

# Sandboxed API
2+
3+
Copyright 2019 Google LLC
4+
5+
![Sandbox](sandboxed_api/docs/images/playing-in-sand.png)
6+
7+
8+
## What is Sandboxed API?
9+
10+
The Sandboxed API project (**SAPI**) aims to make sandboxing of C/C++ libraries
11+
less burdensome: after initial setup of security policies and generation of
12+
library interfaces, an almost-identical stub API is generated (using a
13+
[templated based programming variable hierarchy system](sandboxed_api/docs/variables.md)),
14+
transparently forwarding calls using a custom RPC layer to the real library
15+
running inside a sandboxed environment.
16+
17+
Additionally, each SAPI library utilizes a tightly defined security policy, in
18+
contrast to typical sandboxed project, where security policies must cover total
19+
syscall/resource footprint of all utilized libraries.
20+
21+
22+
## Intended audience
23+
24+
SAPI is designed to help you sandbox only a part of binary. That is, a library
25+
or some other code with an unknown security posture.
26+
27+
See [Sandboxing Code](sandboxed_api/docs/sandbox-overview.md) to make sure this is the type of
28+
sandboxing you are looking for.
29+
30+
## How does it work?
31+
32+
Navigate to our [How it works](sandboxed_api/docs/howitworks.md) page.
33+
34+
35+
## Motivation
36+
37+
Sandboxes available for use in Google required additional implementation work
38+
with each new instance of project which was intended to be sandboxed, even if
39+
it reused the same software library. Sandbox security policies and other
40+
restrictions applied to the sandboxed process had to be reimplemented each
41+
time, and data exchange mechanisms between trusted and untrusted parts of
42+
the code had to be designed from the scratch.
43+
44+
While designing the Sandboxed API project, our goal was to make this process
45+
easy and straightforward. Our working motto is: **Sandbox once, use anywhere**.
46+
47+
48+
## Is it proven technology?
49+
50+
The project has been designed, developed and is maintained by members of
51+
the Google Sandbox Team. It also uses our field-tested
52+
[Sandbox 2](sandboxed_api/sandbox2/README.md).
53+
54+
Currently, many internal projects are already using SAPI to isolate
55+
their production workloads. You can read more about them in the
56+
[Examples](sandboxed_api/docs/examples.md) section.
57+
58+
We've also prepared some more example SAPI implementations for your reference.
59+
60+
61+
## Quick Start
62+
63+
Install the required dependencies, this assumes you are running Debian 10
64+
"Buster":
65+
66+
```bash
67+
echo "deb http://storage.googleapis.com/bazel-apt stable jdk1.8" | \
68+
sudo tee /etc/apt/sources.list.d/bazel.list
69+
wget -qO - https://bazel.build/bazel-release.pub.gpg | sudo apt-key add -
70+
sudo apt-get install -qy python-typing python-clang-7 libclang-7-dev
71+
sudo apt-get install -qy build-essential linux-libc-dev bazel
72+
```
73+
74+
Clone and run the build:
75+
```bash
76+
git clone github.com/google/sandboxed-api && cd sandboxed-api
77+
bazel build ...
78+
```
79+
80+
Try out one of the [examples](sandboxed_api/docs/examples.md):
81+
```bash
82+
bazel run //sandboxed_api/examples/stringop:main_stringop
83+
```
84+
85+
There are also a more detailed instructions that should help you
86+
**[getting started with SAPI](sandboxed_api/docs/getting-started.md)**.
87+
88+
89+
