This adds a way to re-enable justification and hyphenation for
the man page (which in enabled by default in troff but then
Docbook explicitly disables it). The man page looks better this way.
The reason why hyphenation for man pages is disabled by Docbook is
"The problem is that groff is not particularly smart about how it
does hyphenation; it can end up hyphenating a lot of things that you
don't want hyphenated".
The reason why justification for man pages is disabled by Docbook is
"justified text looks good only when it is also hyphenated.
Without hyphenation, excessive amounts of space often end up
getting between words, in order to "pad" lines out to align
on the right margin".
I carefully checked the resuling man page using both terminal output
on 80 columns and the PS/PDF generated. In both cases hyphenation
looks normal, i.e. I don't see any unwanted cases of extra hyphenation.
Same for justification.

The "criu check" command to check if the kernel is properly configured
to run criu is broken.
The "criu check --ms" command used to be the way to tell criu to check
only for features that have been merged upstream. But recent kernels
have a set of features whose presence doesn't necessarily mean that
dump or restore will fail but rather *may* fail depending on whether
the process tree uses those features.
This patch deprecates --ms and introduces --extra, --experimental,
and --all. See "criu --help" or "man criu" for more info.
Typical use cases are:
$ sudo criu check
<zero or more warnings and errors...>
Looks good.
$ echo $?
0
$ sudo criu check --extra
<zero or more warnings and errors...>
Looks good.
$ echo $?
1
$ sudo criu check --extra
<one or more warnings...>
Looks good but some kernel features are missing
which, depending on your process tree, may cause
dump or restore failure.
$ echo $?
1
$ sudo criu check --feature list
mnt_id aio_remap timerfd tun userns fdinfo_lock seccomp_suspend \
seccomp_filters loginuid cgroupns
$ sudo criu check --feature mnt_id

Sometimes we may want to use CRIU on older kernels which don't support
dumping seccomp state where we don't actually care about the seccomp state.
Of course this is unsafe, but it does allow for c/r of things using
seccomp on these older kernels in some cases. When the task is in
SECCOMP_MODE_STRICT or SECCOMP_MODE_FILTER with filters that block the
syscalls criu's parasite code needs, the dump will still fail.
Note that we disable seccomp by simply feigning that we are in mode 0. This
is a little hacky, but avoids distributing ifs throughout the code and
keeps them in this one place.

For example currently in PCS7 we're bindmount cgroups which belong
to a container in a form of
/sys/fs/cgroup/<controller>/<container> ==> /sys/fs/cgroup/<controller>
so that CRIU dumps such configuration fine but on restore
it recreates controllers from the scratch which we would
like to bindmount them and ask CRIU to restore subcgroups
and their parameters.
So I extended --manage-cgroups option to take <mode> arguments.

|
|
|
| NAME
| criu - checkpoint/restore in userspace
|
| SYNOPSIS
| criu <command> [options]
|
| DESCRIPTION
| criu is a tool for checkpointing and restoring running applications. It
| does this by saving their state as a collection of files (see the dump
| command) and creating equivalent processes from those files (see the
| restore command). The restore operation can be performed at a later
| time, on a different system, or both.
|
| OPTIONS
| The options are depending on the <command> criu run with.
|
| Common options
| Common options are applied to any <command>.
|
| -v[<num>|v...]
| Set logging level to <num>. The higer the level, the more output is
| produced. Either numeric values or multiple v can be used.
|
| The following levels are available:
|
| · -v1, -v only messages and errors;
|
| · -v2, -vv also warnings (default level);
|
| · -v3, -vvv also information messages and timestamps;
|
| · -v4, -vvvv lots of debug.
|
| --pidfile <file>
| Write root task, service or page-server pid into a <file>.
|
| -o, --log-file <file>
| Write logging messages to <file>.
|
| --log-pid
| Write separate logging files per each pid.
|
| -D, --images-dir <path>
| Use path <path> as a base directory where to look for dump files
| set.
|
| --prev-images-dir <path>
| Use path <path> as a parent directory where to look for dump files
| set. This make sence in case of increment dumps.
|
| -W, --work-dir <dir>
| Use directory <dir> for putting logs, pidfiles and statistics. If
| not specified, <path> from -D option is taken.
|
| --close <fd>
| Close file with descriptor <fd> before any actions.
|
| -L, --libdir <path>
| Path to a plugins directory.
|
| --action-script <SCRIPT>
| Add an external action script. The environment variable
| CRTOOLS_SCRIPT_ACTION contains one of the actions:
|
| · post-dump run an action upon dump completion;
|
| · post-restore run an action upon restore completion;
|
| · network-lock lock network in a target network namespace;
|
| · network-unlock unlock network in a target network namespace;
|
| · setup-namespaces run an action once root task just been created
| with required namespaces, note it is early stage on restore
| nothing were restored yet except namespaces themselves.
|
| -V, --version
| Print program version and exit.
|
| -h, --help
| Print a commands list and exit. The commands list is very short one
| just for overview and does not match this manual.
|
| pre-dump
| Launches that named pre-dump procedure, where criu does snapshot of
| memory changes since previous pre-dump. Also criu forms fsnotify cache
| which speedup restore procedure. pre-dump requires at least -t option
| (see dump below). Optionally page-server options may be specified.
|
| --track-mem
| Turn on memory changes tracker in the kernel. If the option is not
| passed the memory tracker get turned on implicitly.
|
| dump
| Starts a checkpoint procedure.
|
| -t, --tree <pid>
| Checkpoint the whole process tree starting from <pid>.
|
| -R, --leave-running
| Leave tasks in running state after checkpoint instead of killing
| them. This option is pretty dangerous and should be used if and
| only if you understand what you are doing.
|
| If task is about to run after been checkpointed it can modify TCP
| connections, delete files and do other dangerous actions. So that
| criu itself can not guarantee that the next restore action will not
| fail. Most likely if a user starts criu with this option passed at
| least the file system snapshot must be done with help of post-dump
| script.
|
| In other words, do not use it until really needed.
|
| -s, --leave-stopped
| Leave tasks in stopped state after checkpoint instead of killing
| them.
|
| -x, --ext-unix-sk
| Dump external unix sockets.
|
| -n, --namespaces <ns>[,<ns>...]
| Checkpoint namespaces. Namespaces must be separated by comma.
| Currently supported namespaces: uts, ipc, mnt, pid, net.
|
| --manage-cgroups
| Collect cgroups into the image thus they gonna be restored then.
| Without this argument criu will not save cgroups configuration
| associated with a task.
|
| --tcp-established
| Checkpoint established TCP connections.
|
| --veth-pair <IN>=<OUT>
| Correspondence between outside and inside names of veth devices.
|
| --evasive-devices
| Use any path to a device file if the original one is inaccessible.
|
| --page-server
| Send pages to a page server (see page-server command).
|
| --force-irmap
| Force resolving names for inotify and fsnotify watches.
|
| --auto-dedup
| Deduplicate "old" data in pages images of previous dump. Which
| implies incremental dump mode (see pre-dump command).
|
| -l, --file-locks
| Dump file locks. It is necessary to make sure that all file lock
| users are taken into dump, so it is only safe to use this for
| enclojured containers where locks are not holed by someone outside
| of it.
|
| -M, --ext-mount-map <KEY>:<VAL>
| Setup mapping for external mounts. <KEY> is a mountpoint inside
| container and corresponding <VAL> is a string that will be written
| into the image as mountpoint's root value.
|
| --link-remap
| Allow to link unlinked files back when possible (modifies FS till
| restore).
|
| -j, --shell-job
| Allow to dump shell jobs. This implies the restored task will
| inherit session and process group ID from the criu itself. Also
| this option allows one to migrate a single external tty connection,
| in other words this option allows one to migrate such application
| as "top" and friends. If passed on dump it must be specified on
| restore as well.
|
| --cpu-cap [,<cap>]
| Specify cap CPU capability to be written into an image file.
| Basically if <cap> is one of all, cpu or ins, then criu writes CPU
| related information into image file. If the option is omitted or
| set to none then image will not be written. By default criu do not
| write this image.
|
| restore
| Restores previously checkpointed processes.
|
| --inherit-fd fd[<num>]:<existing>
| Inherit file descriptors. This allows to treat file descriptor
| <num> as being already opened via <existing> one and instead of
| trying to open we inherit it.
|
| -d, --restore-detached
| Detach criu itself once restore is complete.
|
| -S, --restore-sibling
| Restore root task as a sibling (make sense with --restore-detached)
| only.
|
| -r, --root <path>
| Change the root filesystem to <path> (when run in mount namespace).
|
| --manage-cgroups
| Restore cgroups configuration associated with a task from the
| image.
|
| --cgroup-root [<controller>:]/<newroot>
| Change the root cgroup the controller will be installed into. No
| controller means that root is the default for all controllers not
| specified.
|
| --tcp-established
| Restore previously dumped established TCP connections. This implies
| that the network has been locked between dump and restore phases so
| other side of a connection simply notice a kind of lag.
|
| --veth-pair <IN>=<OUT>
| Correspondence between outside and inside names of veth devices.
|
| -l, --file-locks
| Restore file locks from the image.
|
| -M, --ext-mount-map <KEY>:<VAL>
| Setup mapping for external mounts. <KEY> is the value from the
| image (<VAL> from dump) and the <VAL> is the path on host that will
| be bind-mounted into container (to the mountpoint path from image).
|
| --ext-mount-map auto
| This is a special case. If this flag is passed, when an external
| mount is missing from the command line --ext-mount-map <KEY>:<VAL>
| syntax, criu attempts to automatically resolve this mount from its
| namespace.
|
| --enable-external-sharing, --enable-external-masters
| These flags enable external shared or slave mounts to be resolved
| automatically when --ext-mount-map auto is passed.
|
| --auto-dedup
| As soon as a page is restored it get punched out from image.
|
| -j, --shell-job
| Restore shell jobs, in other words inherit session and process
| group ID from the criu itself.
|
| --cpu-cap [<cap>,<cap>]
| Specify <cap> CPU capability to be present on the CPU the process
| is restoring. To inverse capability prefix it with ^. This option
| implies that --cpu-cap has been passed on dump as well, except fpu
| option case.
|
| · all. Require all capabilities. This is default mode if
| --cpu-cap is passed without arguments. Most safe mode.
|
| · cpu. Require the CPU to have all capabilities in image to match
| runtime CPU.
|
| · fpu. Requre the CPU to have comaptible FPU. For example the
| process might be dumped with xsave capability but attempted to
| restore without it present on target CPU. In such case we
| refuse to procceed. This is default mode if --cpu-cap is not
| present in command line. Note this argument might be passed
| even if on the dump no --cpu-cap have been specified becase FPU
| frames are always encoded into images.
|
| · ins. Require CPU compatibility on instructions level.
|
| · none. Ignore capabilities. Most dangerous mode. The behaviour
| is implementation dependent. Try to not use it until really
| required.
|
| One possible need of using this option is when --cpu-cap=cpu
| has been passed on dump then images are migrated to a less
| capable processor and one need to restore this application, by
| default criu will refuse to proceed without relaxing capability
| with --cpu-cap=none parameter.
|
| check
| Tests wheter the kernel support is up to date.
|
| --ms
| Do not check not yet merged features.
|
| --feature <name>
| Check a particular feature. Instead of checking everything one may
| specify which exactly feature is to be tested. The <name> may be:
| mnt_id, aio_remap, timerfd, tun, userns.
|
| page-server
| Launches criu in page server mode.
|
| --daemon
| Runs page server as a daemon (background process).
|
| --address <address>
| Page server IP address.
|
| --port <number>
| Page server port number.
|
| exec
| Executes a system call inside a destination task's context.
|
| service
| Launches criu in RPC daemon mode where criu is listeninп for RPC
| commands over socket to perform. This is convenient for the case where
| daemon itself is running in a privilege (superuser) mode but clients
| are not.
|
| dedup
| Starts pagemap data deduplication procedure, where criu scans over all
| pagemap files and tries to minimalize the number of pagemap entries by
| obtaining the references from a parent pagemap image.
|
| cpuinfo dump
| Fetches current CPU features and write them into an image file.
|
| cpuinfo check
| Fetches current CPU features (ie CPU the criu is running on) and test
| if they are compatible with ones present in image file.
|
| SYSCALLS EXECUTION
| To run a system call in another task's context use
|
| criu exec -t pid syscall-string
|
| command. The syscall-string should look like
|
| syscall-name syscall-arguments ...
|
| Each command line argument is transformed into the system call argument
| by the following rules:
|
| · If one starts with &, the rest of it gets copied to the target
| task's address space and the respective syscall argument is the
| pointer to this string;
|
| · Otherwise it is treated as a number (converted with strtol) and is
| directly passed into the system call.
|
| EXAMPLES
| To checkpoint a program with pid of 1234 and write all image files into
| directory checkpoint:
|
| criu dump -D checkpoint -t 1234
|
| To restore this program detaching criu itself:
|
| criu restore -d -D checkpoint
|
| To close a file descriptor number 1 in task with pid 1234:
|
| criu exec -t 1234 close 1
|
| To open a file named /foo/bar for read-write in the task with pid 1234:
|
| criu exec -t 1234 open '&/foo/bar' 2

On dump one uses one or more --ext-mount-map option with A:B arguments.
A denotes a mountpoint (as seen from the target mount namespace) criu
dumps and B is the string that will be written into the image file
instead of the mountpoint's root.
On restore one uses the same --ext-mount-map option(s) with similar
A:B arguments, but this time criu treats A as string from the image's
root field (foobar in the example above) and B as the path in criu's
mount namespace the should be bind mounted into the mountpoint.
