3.21.0

3.21.0

Added

• Support for Go's os.ReadDir on Linux (by hooking the getdents64 syscall). Part of
  #120.
• Test mirrord with Go 1.20rc3.

Changed

• mirrord-agent: Wrap agent with a parent proccess to doublecheck the clearing of iptables. See #955
• mirrord-layer: Change HOOK_SENDER from Option to OnceLock.

Fixed

• mirrord-agent: Handle HTTP upgrade requests when the stealer feature is enabled
  (with HTTP traffic) PR #973.
• E2E tests compile on MacOS.
• mirrord could not load into some newer binaries of node -
  #987. Now hooking also posix_spawn, since node now uses
  libuv's uv_spawn (which in turn calls posix_spawn) instead of libc's execvp (which calls execve).
• Read files from the temp dir (defined by the system's TMPDIR) locally, closes
  #986.
