This name for the structure is obfuscating, because the structure will be used also for queues and semaphores sets migration. This patch renames this structure int ipc_desc_entry. It also renames all related functions and prints to reflect structure name change. Signed-off-by:

Since we now have the parasite memory shared with crtools process we can just memcpy this data between them. Signed-off-by:

I don't like that we poke the parasite into remote space with 4k calls to ptrace. Now we have the /proc/pid/map_files/ dir which helps us sharing a mapping with some other process. Use this -- map the remote area for parasite locally and put the parasite blob into it with simple memcpy. Signed-off-by:

In fact all we need for parasitic syscall is -- original regs and some regs with syscall args to work on. The former one is obtained in the infect/cure code and the latter one is located (and copied from orig) nearby. That said, we can simplify all the regs passing-down code by removing intermediate instances and utilizing the top-level reg-s for this. Signed-off-by:

No need in getting regs one more time -- we have the orig_regs at hands. Signed-off-by:

There's no need in 3 instances of regs in arguments. One is more than enough. Plus, this one can be made static. Signed-off-by:

Right now we do syscall_seized for this, but we have the misc dumping command and the core is (after patch #3) dump after parasite, so we can get brk from the misc dump, thus avoiding one more switch to parasite. Signed-off-by:

It's not used in code. Signed-off-by:

This actually does two things: 1. The parasite code writes to pages _or_ to pages_shared file himself based on a hint given from the main program. This avoids shared pages copying in finalize_core. 2. The private pages are moved out of the core file into a separate one. This avoids private pages copying in finalize_core. The goal of this patch is a) to avoid pages copying at all (we still have one on restore, but fixing this requires Andrey's work on shared memory dumping) and b) make big blobs with pages be stored in separate files (I have plans on its format rework and unification).

Only the low 32 bits of orig_ax are meaningful for obtaining syscall number so we need to test if sign extended bits are greater than 0. Reported-by:
