The criu/ptrace.c will also go into compel sources, so detach the needed code from CRIU as well. Signed-off-by:

This header describes CRIU parasite code, it has nothing to do with infect, so remove it. To do this we need to: * Detach infect RPC commands from criu-parasite ones * Move parasite_init_args and parasite_unmap_args into infect * Move PARASITE_AREA_MIN into infect * Hiding PARASITE_STACK_SIZE-s in infect * Hiding parasite symbols resolvers in infect Signed-off-by:

I.e. -- the infect_ctX structure. Now it's in infect.h and is aimed for compel sources. Signed-off-by:

Not only infect() routine but all dependant code too. This is the core of the library actually. Signed-off-by:

This structure will be internal to compel. Users will only see one as opaque pointer and read data from it using calls. Exception for now -- infect_ictx. This is a configuration structure that will be embeded into ctl and seen outside. Signed-off-by:

We'll collect the compel code here and will move all these files into compel library by the last patch of this set. Signed-off-by:

Now we can split the parasite_infect_seized() into CRIU-specific part and independent part that is to become compel code. The API to infect() is for now a bit clumsy, but I will rectify one a bit more in the next patches. Signed-off-by:

This is the address of an executable VMA. To get one we need to parse /proc/pid/maps, compel will do it, but since criu already parses this file (to dump task vmas), we can provide the address via ictx. Signed-off-by:

Two calls -- to keep the registers and to put them back onto sigframe. For CRIU the keeping is performed on CoreEntry. Signed-off-by:

To track victim health state criu sets up the sigchild handler. So will have to do the compel, but the ability to request for own handler would be required. Signed-off-by:

This structure will become the part of compel A[PB]I and will be used by compel clients as configuration structure. For now put there the pointer on a socket living in victim's netns. If empty (-1), compel will create this socket its own, but CRIU already creates such in an effective manner. Signed-off-by:

When seizeing task we need to parse /proc/pid/status for its state, parent, signals and seccomp status. In criu case we also parse other stuff in one go, so make this parsing be a callback which criu will provide. Signed-off-by:

There's a subset of this structure is required by seize_catch_task(), which in turn will go to compel library. So prepare for that. Signed-off-by:

The get_task_regs() call now accepts a pointer on a function that is to keep obtained registers somwehere. In CRIU case this "somewhere" is CoreEntry, for generic compel user we'll need to add simple memcpy()-s to the library itself. Signed-off-by:

First time regs are saved on ctl->orig.regs in parasite_prep_ctl, the 2nd time regs are got inside x86/arch_task_compatible, while it can use the on-ctl copy. travis-ci: success for Don't get task regs twice Signed-off-by:
