Track how close are we towards matching the upstream Occlum

This issue tracks NGO's progress towards matching the functionalities of the upstream Occlum (0.21.0, released on March 3rd, 2021). We quantify the progress in two metrics:

  • Unit tests: the number of unit tests that can pass in NGO versus the one in Occlum.
  • System calls: the number of system calls implemented in NGo versus the one in Occlum.

Currently, the values of the two metrics are

  • Unit tests: 26/45
  • System calls: 87/129.

Read the sections below for more details.

Unit tests

Here is the list of unit tests in NGO. An item is checked if the unit test (at least partially) pass in NGO.

  • access
  • chmod
  • chown
  • cout
  • cpuid
  • device
  • empty
  • emulate_syscall
  • env
  • eventfd
  • exit_group
  • fcntl
  • file
  • fs_perms
  • getpid
  • hello_world
  • hostfs
  • ioctl
  • link
  • malloc
  • mkdir
  • mmap
  • open
  • pipe
  • prctl
  • procfs
  • pthread
  • rdtsc
  • readdir
  • rename
  • rlimit
  • sched
  • server
  • server_epoll
  • signal
  • sleep
  • spawn
  • stat
  • symlink
  • sysinfo
  • time
  • tls
  • truncate
  • uname
  • unix_socket

System calls

Here we list all system calls that are supported in upstream Occlum, but not in NGO, at the time of writing this issue. We keep updating the progress in implementing the missing system calls.
