When building the blob in the generated header file, we may shrink the output blobk and only copy the sections with the SHF_ALLOC bit set, the other ones are not needed at runtime. Signed-off-by:

This cleans the assembly code, removing no more needed trick with the register 2 (TOC pointer). As a consequence, the __export_restore_task_trampoline() and __export_unmap_trampoline() are no more needed. Thus, the changes introduced by the commit de9df910 ("Per architecture restorer trampolines") in cr-restore.c are no more used but are not impacting runtime code anyway. Signed-off-by:

At moment both parasite and restorer do not have any relocs because we support x86-64 only, but this will be changed soon so do a call and apply relocations. Signed-off-by:

We should use provided @nr_relocs instead of ARRAY_SIZE here. Didn't spot it earlier simply because at moment on x86-64 there is no relocs at all. Also when we apply relocation they are to be computed from virtual base of parasite address, not from local memory map address, so add @vbase parameter. And fix typo on addend in gotpcrel.

After this patch one can run ARCH="ia32" make to build 32bit version on CRIU on 64bit host. Note this is only build procedure which tuned up, the CRIU itself is not yet ready to make a checkpoint/restore cycle -- a lot of additional code is needed and here we rather put stubs simply to make build procedure run.

There is no rip addressing in 32bit code but PIE code require GOT tables and friend which we better escape for performance sake. So lets use pc relocations it should do the trick. Signed-off-by:

To support x86-32 mode we will need own syscall table. Here is it. Note the CRIU itself doesn't support such mode yet. Meanwhile put syscall table here just in case if someone is adding new syscall 32 bit variant should be updated as well. Signed-off-by:

Since at the moment we're running only x86-64 not 32 bit tasks, and our code is not carrying any big statically defined structures we can use relocatable files directly with all relocation applied during building. This gonna be changed soon once we start supporting 32 bit tasks. IOW even currently we need (which is not yet done but it's safe) - check for gotpcrel relocations - apply relocations with generated elf_apply_relocs helper Currently overall scheme looks this way - our object files are linked together into parasite.built-in.bin.o file - then pie/piegen/piegen tool is called which parses this file and generates C source code file with bytestream and all information needed to rellocate this bytestream into a new place (see elf_apply_relocs helper) Signed-off-by:

Here we simply build piegen tool which gonna be used to generate parasite code safe to rellocate. The tool is taking object file as an argument, parses it and generates C file with rellocations encoded in form suitable for fast appliance. Currently only x86-32 x86-64 is supported. v2 (by ldufour@): - Filter PIEGEN Signed-off-by:

On restore we have several arrays of objects that get remapped into pie area and their number is also passed. Clean and shorten the remapping code a bit and bing their naming to common format. Signed-off-by: -

The criu(8) man-page is generated using asciidoc. The problem with asciidoc is that, due to its dependencies, it is not available on all distributions or it is undesired to install all asciidoc dependencies. The install target was unconditionally installing and thus building the man-page even if not explicitly specified with 'make docs'. With the new 'install-criu' target everything besides the man-page is installed and the target 'install-man' is only called by the target 'install'. Signed-off-by:

On restore we will use the peer's name to connect() the socket back, so if there's no name dump should be aborted. This situation happens when we create a socketpair(), fork and dump only one task with one pair end. Reported-by:

Use SIG_SETMASK instead of SIG_BLOCKMASK here in case the parent had SIGCHLD blocked. In this case if one of the criu threads has a problem, since the SIGCHLD is blocked, the restore simply hangs. Signed-off-by:

So, we've got quite a lot of new stuff this release :) The biggest code-merge was POWER arch port. Another big thing that has happened was criu integration with libcontainer. And a tiny change that will become big next release -- the "criu show" command is going to be thrown away in 3 monthes, the CRIT tool should be used instead. Signed-off-by:

When we call open_proc(PROC_SELF, ...) the /proc/self descriptor is cached in criu. If the process fork()-s after than and child goes open_proc(PROC_SELF, ...) then it will get the parent's proc descriptor. Signed-off-by:

If dump doesn't generate data into some image file the respective file is not created at all as it used to be in 1.5. This brings potential problem -- if the file with the image name exists during dump (e.g. a dump file left from previous, maybe unsuccessful, dump) then restore would pick this file and read bad/wrong/fake data from it. To return the proper behavior back the file with the name of empty image should be removed. Signed-off-by: -

In case if we've dumped read only tmpfs we fail restoring it because it's mounted with ro flags. Lets mount it with rw, restore content and then remount as ro. upd (by xemul@): any fs with restore method likely to need rw permission on restore. Signed-off-by:
