PiperOrigin-RevId: 320290162
2020-07-08ip6tables: handle both IPv4 and v6 addressesKevin Krakauer
Enabling IPv6 in Docker caused IPv4 tests to fail because localAddrs didn't distinguish between address types. Example failure: https://source.cloud.google.com/results/invocations/203b2401-3333-4bec-9a56-72cc53d68ddd/log
2020-07-08Move all tests to new docker API.Zach Koopmans
Moves following to new dockerutil API: - //test/e2e:integration_test - //test/image:image_test - //test/iptables:iptables_test - //test/root:root_test - //test/packetimpact:packetimpact_test PiperOrigin-RevId: 320253118
2020-06-17Move mount configutation to RunOptsFabricio Voznika
Separate mount configuration from links and move it to RunOpts, like the other options. PiperOrigin-RevId: 317010158
2020-06-05iptables: loopback traffic skips prerouting chainKevin Krakauer
Loopback traffic is not affected by rules in the PREROUTING chain. This change is also necessary for istio's envoy to talk to other components in the same pod.
2020-05-28Enable iptables source filtering (-s/--source)Kevin Krakauer
2020-05-12iptables: support gid match for owner matching.Nayana Bidari
- Added support for matching gid owner and invert flag for uid and gid. $ iptables -A OUTPUT -p tcp -m owner --gid-owner root -j ACCEPT $ iptables -A OUTPUT -p tcp -m owner ! --uid-owner root -j ACCEPT $ iptables -A OUTPUT -p tcp -m owner ! --gid-owner root -j DROP - Added tests for uid, gid and invert flags.
2020-05-08iptables - filter packets using outgoing interface.gVisor bot
Enables commands with -o (--out-interface) for iptables rules. $ iptables -A OUTPUT -o eth0 -j ACCEPT PiperOrigin-RevId: 310642286
2020-05-01Support for connection tracking of TCP packets.Nayana Bidari
Connection tracking is used to track packets in prerouting and output hooks of iptables. The NAT rules modify the tuples in connections. The connection tracking code modifies the packets by looking at the modified tuples.
2020-04-23Simplify Docker test infrastructure.Adin Scannell
This change adds a layer of abstraction around the internal Docker APIs, and eliminates all direct dependencies on Dockerfiles in the infrastructure. A subsequent change will automated the generation of local images (with efficient caching). Note that this change drops the use of bazel container rules, as that experiment does not seem to be viable. PiperOrigin-RevId: 308095430
2020-03-26Support owner matching for iptables.Nayana Bidari
This feature will match UID and GID of the packet creator, for locally generated packets. This match is only valid in the OUTPUT and POSTROUTING chains. Forwarded packets do not have any socket associated with them. Packets from kernel threads do have a socket, but usually no owner.

2020-03-11iptables: ready tests to be enabled in kokoroKevin Krakauer
Fixed flakes (tested via --runs_per_test=100) and added skips for not-yet-implemented features. Once submitted, the iptables tests will be ready to enable in kokoro.
2020-02-26iptables: filter by IP address (and range)Kevin Krakauer
Enables commands such as: $ iptables -A INPUT -d 127.0.0.1 -j ACCEPT $ iptables -t nat -A PREROUTING ! -d 127.0.0.1 -j REDIRECT Also adds a bunch of REDIRECT+destination tests.

2020-02-18Add nat table support for iptables.Nayana Bidari
Add nat table support for Prerouting hook with Redirect option. Add tests to check redirect of ports.
2020-02-13We can now create and jump in iptables. For example:Kevin Krakauer
$ iptables -N foochain $ iptables -A INPUT -j foochain
2020-02-12iptables: User chainsKevin Krakauer
- Adds creation of user chains via `-N <chainname>` - Adds `-j RETURN` support for built-in chains, which triggers the chain's underflow rule (usually the default policy). - Adds tests for chain creation, default policies, and `-j RETURN' from built-in chains.
2020-01-29Fix iptables tests that were broken by rename.Kevin Krakauer
The name of the runner binary target changed from "runner" to "runner-image", causing iptables tests to fail. PiperOrigin-RevId: 292242263

2020-01-13Add test for iptables TCP ruleNayana Bidari
Added tests for tcp protocol with input and output rules including options sport and dport Increased timeout in iptables_test as TCP tests were timing out with existing value.
2020-01-10Add tests for redirect portNayana Bidari
Fix indentation and change function names.
2020-01-09Add test for redirect portNayana Bidari
Fix the indentation and print statements. Moved the NAT redirect tests to new file. Added negative test to check redirect rule on ports other than redirected port.

2020-01-08Write simple ACCEPT rules to the filter table.Kevin Krakauer
This gets us closer to passing the iptables tests and opens up iptables so it can be worked on by multiple people. A few restrictions are enforced for security (i.e. we don't want to let users write a bunch of iptables rules and then just not enforce them): - Only the filter table is writable. - Only ACCEPT rules with no matching criteria can be added.
2019-12-12Add iptables testing framework.Kevin Krakauer
It would be preferrable to test iptables via syscall tests, but there are some problems with that approach: * We're limited to loopback-only, as syscall tests involve only a single container. Other link interfaces (e.g. fdbased) should be tested. * We'd have to shell out to call iptables anyways, as the iptables syscall interface itself is too large and complex to work with alone. * Running the Linux/native version of the syscall test will require root, which is a pain to configure, is inherently unsafe, and could leave host iptables misconfigured. Using the go_test target allows there to be no new test runner. PiperOrigin-RevId: 285274275
