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.

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.

2019-01-16Prevent internal tmpfs mount to override files in /tmpFabricio Voznika
Runsc wants to mount /tmp using internal tmpfs implementation for performance. However, it risks hiding files that may exist under /tmp in case it's present in the container. Now, it only mounts over /tmp iff: - /tmp was not explicitly asked to be mounted - /tmp is empty If any of this is not true, then /tmp maps to the container's image /tmp. Note: checkpoint doesn't have sentry FS mounted to check if /tmp is empty. It simply looks for explicit mounts right now.

2019-01-09Make CooperativeSaveEnabled() async-signal-safe(r).Jamie Liu
The static local variable `enabled` in CooperativeSaveEnabled() is not initialized until the first call to CooperativeSaveEnabled(), per the C++14 standard, section 6.7 ("Declaration statement"), paragraph 4. This initialization is thread-safe as of C++11, but it is *not* required to be async-signal-safe. Use a namespace-scope variable instead, since this is guaranteed to be zero-initialized before main() by section 3.6.2 ("Initialization of non-local variables"). getenv() is technically not async-signal-safe either, hence the hedging in the change summary line. However, glibc's implementation of getenv() appears to be async-signal-safe in the absence of calls to setenv(). PiperOrigin-RevId: 228588617 Change-Id: I669f555d1c91352d55c606970bb237ec888fa7ca
