2019-03-08Make IP_MULTICAST_LOOP and IP_MULTICAST_TTL allow setting int or char.Ian Gudger
This is the correct Linux behavior, and at least PHP depends on it. PiperOrigin-RevId: 237565639 Change-Id: I931af09c8ed99a842cf70d22bfe0b65e330c4137

PiperOrigin-RevId: 237559843 Change-Id: I93a9d83a08cd3d49d5fc7fcad5b0710d0aa04aaa
2019-03-08Implement IP_MULTICAST_LOOP.Ian Gudger
IP_MULTICAST_LOOP controls whether or not multicast packets sent on the default route are looped back. In order to implement this switch, support for sending and looping back multicast packets on the default route had to be implemented. For now we only support IPv4 multicast.

2019-03-06Remove unsafe ScopedSigactionMichael Pratt
ScopedSigaction is not async-signal-safe, so it cannot be used after fork. Replace it with plain sigaction, which is safe. This is in a unique child anyways, so it doesn't need any cleanup. PiperOrigin-RevId: 237102411 Change-Id: I5c6ea373bbac67b9c4db204ceb1db62d338d9178
2019-03-05Priority-inheritance futex implementationFabricio Voznika
It is Implemented without the priority inheritance part given that gVisor defers scheduling decisions to Go runtime and doesn't have control over it. PiperOrigin-RevId: 236989545 Change-Id: I714c8ca0798743ecf3167b14ffeb5cd834302560
2019-03-05Add NoRandomSave to tests with correctness DisableSaveMichael Pratt
Tests using DisableSave because a portion of the test is *incompatible* with S/R clearly cannot use random S/R, as the saves may occur in the DisableSave critical section. Most such tests already have NoRandomSave. Add it to the rest. PiperOrigin-RevId: 236914708 Change-Id: Iee1cf044cfa7cb8d5aba21ddc130926218210c48

2019-02-28Fix flaky raw socket test.Kevin Krakauer
The specific issue was: - Test creates a raw ICMP socket - Test sends an ICMP echo request (aka ping request) to itself via loopback - Now two events race: - The raw socket recieves the ICMP echo request - Netstack receives the request and generates a reply (aka ping reply), which it sends back over loopback, where it is eventually received by the raw socket - The test was written to expect packets in a specific order, but they can come in any order.

2019-02-27Ping support via IPv4 raw sockets.Kevin Krakauer
Broadly, this change: * Enables sockets to be created via `socket(AF_INET, SOCK_RAW, IPPROTO_ICMP)`. * Passes the network-layer (IP) header up the stack to the transport endpoint, which can pass it up to the socket layer. This allows a raw socket to return the entire IP packet to users. * Adds functions to stack.TransportProtocol, stack.Stack, stack.transportDemuxer that enable incoming packets to be delivered to raw endpoints. New raw sockets of other protocols (not ICMP) just need to register with the stack. * Enables ping.endpoint to return IP headers when created via SOCK_RAW.

2019-02-20Implement Broadcast supportAmanda Tait
This change adds support for the SO_BROADCAST socket option in gVisor Netstack. This support includes getsockopt()/setsockopt() functionality for both UDP and TCP endpoints (the latter being a NOOP), dispatching broadcast messages up and down the stack, and route finding/creation for broadcast packets. Finally, a suite of tests have been implemented, exercising this functionality through the Linux syscall API. PiperOrigin-RevId: 234850781 Change-Id: If3e666666917d39f55083741c78314a06defb26c

2019-02-19Break /proc/[pid]/{uid,gid}_map's dependence on seqfile.Jamie Liu
In addition to simplifying the implementation, this fixes two bugs: - seqfile.NewSeqFile unconditionally creates an inode with mode 0444, but {uid,gid}_map have mode 0644. - idMapSeqFile.Write implements fs.FileOperations.Write ... but it doesn't implement any other fs.FileOperations methods and is never used as fs.FileOperations. idMapSeqFile.GetFile() => seqfile.SeqFile.GetFile() uses seqfile.seqFileOperations instead, which rejects all writes.

2019-01-25Remove O_CLOEXEC from socket test configurations where irrelevant.Jamie Liu
The implementation of O_CLOEXEC is orthogonal to every property tested by these tests; removing it significantly reduces the number of redundant tests we run.

2019-01-24Explicitly std::move() returned std::vector<Mapping>.Jamie Liu
Otherwise, C++11-compliant compilers may select PosixErrorOr(const T&) as the relevant constructor, and fail because std::vector<Mapping> is not copyable (because Mapping is not copyable). This is a C++11 defect that is fixed in C++14 (and in C++11 mode for Clang, but not GCC). See DR 1579, http://www.open-std.org/jtc1/sc22/wg21/docs/cwg_defects.html#1579.

2018-12-27Fix deadlock between epoll_wait and getdentsFabricio Voznika
epoll_wait acquires EventPoll.listsMu (in EventPoll.ReadEvents) and then calls Inotify.Readiness which tries to acquire Inotify.evMu. getdents acquires Inotify.evMu (in Inotify.queueEvent) and then calls readyCallback.Callback which tries to acquire EventPoll.listsMu. The fix is to release Inotify.evMu before calling Queue.Notify. Queue is thread-safe and doesn't require Inotify.evMu to be held.
