crtools-0.3.tar.bz2
Released: 11 Dec 2012
GIT tag: v0.3

New features[edit]

  • C/R of shell jobs
  • Handle files, that are opened and unlinked, but some other hard link exists
  • More SOL_SOCKET socket options. Two most interesting are:
    • Binding socket to device (SO_BINDTODEVICE)
    • Per-socket packet filter (SO_ATTACH_FILTER)
  • Shutdown state of a socket
  • Task scheduler parameters (nice, policy and prio)
  • Properly handle COW pages
  • Memory mapped packet sockets (with SOL- options this is enough for tcpdump tool support)
  • Complementary groups (getgroups(2))
  • Various mapping features, configured with madvise(2)
  • Tune TCP sockets support to work with IPv6 sockets
  • Closed (or not yet connected/bound) unix sockets

Bug fixes and improvements[edit]

    • Arch-specific code in arch/<Arch>/ directory

  • Fixed livelocks when restoring too big socket queues
  • Refresh info about sockets, that might have changed between diag dump and actual process freeze
  • Lost file params and socket options for some unix sockets
  • Fix inotify on opened and unlinked files
  • Fix shared anonymous memory detection
  • Properly close all files before restoring them
  • Fixes in running external tools (ip/tar)
