2020-02-20Initial network namespace support.gVisor bot
TCP/IP will work with netstack networking. hostinet doesn't work, and sockets will have the same behavior as it is now. Before the userspace is able to create device, the default loopback device can be used to test. /proc/net and /sys/net will still be connected to the root network stack; this is the same behavior now. Issue #1833 PiperOrigin-RevId: 296309389
2020-02-19Add basic microbenchmarks.Adin Scannell
PiperOrigin-RevId: 296104390
2020-02-19Include more test files in exports_filesgVisor bot
So that they can be included by Fuchsia's syscall tests PiperOrigin-RevId: 296030383
2020-02-18Enable IPV6_RECVTCLASS socket option for datagram socketsgVisor bot
Added the ability to get/set the IP_RECVTCLASS socket option on UDP endpoints. If enabled, traffic class from the incoming Network Header passed as ancillary data in the ControlMessages. Adding Get/SetSockOptBool to decrease the overhead of getting/setting simple options. (This was absorbed in a CL that will be landing before this one). Test: * Added unit test to udp_test.go that tests getting/setting as well as verifying that we receive expected TOS from incoming packet. * Added a syscall test for verifying getting/setting * Removed test skip for existing syscall test to enable end to end test.

PiperOrigin-RevId: 294952610
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.

2020-02-10iptables: add instructions for runsc building.Kevin Krakauer
The readme didn't mention that users need to: - `bazel build` when working on iptables tests - enable raw sockets in /etc/docker/daemon.json. PiperOrigin-RevId: 294260169

2020-02-07Support listxattr and removexattr syscalls.Dean Deng
Note that these are only implemented for tmpfs, and other impls will still return EOPNOTSUPP. PiperOrigin-RevId: 293899385
2020-02-07Refactor syscall testsJay Zhuang
- Move shared helpers V4Multicast and V4Broadcast to socket_test_util - Add unnamed namespace so socket_ipv4_tcp_unbound_external_networking_test.cc and socket_ipv4_udp_unbound_external_networking_test.cc can be compiled together - Add test files to "exports_files" so they can be included by Fuchsia's syscall test setup PiperOrigin-RevId: 293880429

These were out-of-band notes that can help provide additional context and simplify automated imports. PiperOrigin-RevId: 293525915
2020-02-05recv() on a closed TCP socket returns ENOTCONNEyal Soha
From RFC 793 s3.9 p58 Event Processing: If RECEIVE Call arrives in CLOSED state and the user has access to such a connection, the return should be "error: connection does not exist" Fixes #1598 PiperOrigin-RevId: 293494287

2020-02-04Add socket connection stress test.Ian Gudger
Tests 65k connection attempts on common types of sockets to check for port leaks. Also fixes a bug where dual-stack sockets wouldn't properly re-queue segments received while closing. PiperOrigin-RevId: 293241166

2020-02-04Add support for sentry internal pipe for gofer mountsFabricio Voznika
Internal pipes are supported similarly to how internal UDS is done. It is also controlled by the same flag. Fixes #1102 PiperOrigin-RevId: 293150045
2020-02-03Reduce run time for //test/syscalls:socket_inet_loopback_test_runsc_ptrace.Ting-Yu Wang
* Tests are picked for a shard differently. It now picks one test from each block, instead of picking the whole block. This makes the same kind of tests spreads across different shards. * Reduce the number of connect() calls in TCPListenClose. PiperOrigin-RevId: 293019281

2020-01-31Fix logic around AMD/Intel cases.Adin Scannell
If the support is Ignored, then the call is still executed. We simply rely on it to fall through to the int3. Therefore, we must also bail on the vendor check. PiperOrigin-RevId: 292620558

2020-01-30Fix for panic in endpoint.Close().Bhasker Hariharan
When sending a RST on shutdown we need to double check the state after acquiring the work mutex as the endpoint could have transitioned out of a connected state from the time we checked it and we acquired the workMutex. I added two tests but sadly neither reproduce the panic. I am going to leave the tests in as they are good to have anyway. PiperOrigin-RevId: 292393800
2020-01-30Enforce splice offset limitsMichael Pratt
Splice must not allow negative offsets. Writes also must not allow offset + size to overflow int64. Reads are similarly broken, but not just in splice (b/148095030). Reported-by: syzbot+0e1ff0b95fb2859b4190@syzkaller.appspotmail.com PiperOrigin-RevId: 292361208
2020-01-29Fix iptables tests that were broken by rename.Kevin Krakauer

2020-01-28fs/splice: don't report partial errors for special filesAndrei Vagin
Special files can have additional requirements for granularity. For example, read from eventfd returns EINVAL if a size is less 8 bytes. Reported-by: syzbot+3905f5493bec08eb7b02@syzkaller.appspotmail.com PiperOrigin-RevId: 292002926

2020-01-28Check sigsetsize in rt_sigactionMichael Pratt
This isn't in the libc wrapper, but it is in the syscall itself. Discovered by @xiaobo55x in #1625. PiperOrigin-RevId: 291973931
2020-01-28Prefer Type& over Type &Michael Pratt
And Type* over Type *. This is basically a whitespace only change. gVisor code already prefers left-alignment of pointers and references, but clang-format formats for consistency with the majority of a file, and some files leaned the wrong way. This is a one-time pass to make us completely conforming. Autogenerated with: $ find . \( -name "*.cc" -or -name "*.c" -or -name "*.h" \) \ | xargs clang-format -i -style="{BasedOnStyle: Google, \ DerivePointerAlignment: false, PointerAlignment: Left}" PiperOrigin-RevId: 291972421
