2020-09-16Rename marshal.Task to marshal.CopyContext.Rahat Mahmood
CopyContext is a better name for the interface because from go-marshal's perspective, the interface has nothing to do with a task. A kernel.Task happens to implement the interface, but so can other things like MemoryManager and IO sequences. PiperOrigin-RevId: 331959678

2020-09-15Add support for OCI seccomp filters in the sandbox.Ian Lewis
OCI configuration includes support for specifying seccomp filters. In runc, these filter configurations are converted into seccomp BPF programs and loaded into the kernel via libseccomp. runsc needs to be a static binary so, for runsc, we cannot rely on a C library and need to implement the functionality in Go. The generator added here implements basic support for taking OCI seccomp configuration and converting it into a seccomp BPF program with the same behavior as a program generated by libseccomp. - New conditional operations were added to pkg/seccomp to support operations available in OCI. - AllowAny and AllowValue were renamed to MatchAny and EqualTo to better reflect that syscalls matching the conditionals result in the provided action not simply SCMP_RET_ALLOW. - BuildProgram in pkg/seccomp no longer panics if provided an empty list of rules. It now builds a program with the architecture sanity check only. - ProgramBuilder now allows adding labels that are unused. However, backwards jumps are still not permitted.

2020-09-11Implement FUSE_SETATTRCraig Chi
This commit implements FUSE_SETATTR command. When a system call modifies the metadata of a regular file or a folder by chown(2), chmod(2), truncate(2), utime(2), or utimes(2), they should be translated to corresponding FUSE_SETATTR command and sent to the FUSE server. Fixes #3332
2020-09-11Add fh support for revise attr and fstat(2) testCraig Chi
According to Linux 4.4's FUSE behavior, the flags and fh attributes in FUSE_GETATTR are only used in read, write, and lseek. fstat(2) doesn't use them either. Add tests to ensure the requests sent from FUSE module are consistent with Linux's. Updates #3655
2020-09-11Implement FUSE_WRITEJinmou Li
This commit adds basic write(2) support for FUSE.
2020-09-11Implement FUSE_CREATECraig Chi
FUSE_CREATE is called when issuing creat(2) or open(2) with O_CREAT. It creates a new file on the FUSE filesystem. Fixes #3825

2020-09-11fuse: remove unused marshalling functionsCraig Chi
This commit removes unused marshalling functions in linux abi package and moves self-defined FUSEInitRes wrapper to fuse package. Updates #3707
2020-09-11Support multiple FUSE kernel versions of FUSE_INIT response structCraig Chi
The fuse_init_out struct changes in different FUSE kernel versions. A FUSE server may implement older versions of fuse_init_out, but they share common attributes from the beginning. Implement variable-length marshallable interface to support older versions of ABI. Fixes #3707
2020-09-11fuse: use safe go_marshal API for FUSERidwan Sharif
Until #3698 is resolved, this change is needed to ensure we're not corrupting memory anywhere.
