v. 0.4

crtools-0.4.tar.bz2
Released: 20 Feb 2013
GIT tag: v0.4

New features

• ARM port
• Remote syscall execution
• C/R of
  • FPU state
  • File locks (basic support)
  • Rlimits
  • FANotify descriptors
  • Shared fdtable (table of file descriptors)
  • Tasks' umask
  • Pipe buffer size
  • Unix sockets' credentials
  • TCP time-stamp offset (allows to migrate a TCP socket, requires custom kernel)
• Automatic namespaces detection (--namespace option is deprecated)

Internal

• Build system rework
• Dumping/restoring memory pointers standardized (while doing ARM port)
• Ability to collect coverage (gcov, reported here)
• 32/64-bit problems mostly resolved (while doing ARM port)

v. 0.3

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

New features

• 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

• Print timestamps in log files
• Restructure source tree a little
  • PIE stuff in separate dir
  • Arch-specific code in arch/<Arch>/ directory
• Nicer show -c output for pages/pipes/etc contents
• Fixes in help text
• Save and restore blocked signals mask for threads
• Don't dump (and warn about it) corked UDP sockets
• 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)
• Several fixes in control tty restoring code
• RT signals handlers dumped and restored
