@std plugin known to fail when trying to execute, investigating now. Meanwhile to not block tests lets use syscalls object file. Signed-off-by:

And use it in CRIU directly instead: - move syscalls into compel/arch/ARCH/plugins/std/syscalls - drop old symlinks - no build for 32bit on x86 as expected - use std.built-in.o inside criu directly (compel_main stub) - drop syscalls on x86 criu directory, I copied them already in first compel commist, so we can't move them now, but delete in place Signed-off-by:

Real syscalls generation is inside criu for a while but will be moved out in the next patch. Signed-off-by:

CRIU will reference to them, but for now they are just stubs. Signed-off-by:

Both std and criu will use it for syscalls sake. Note I've to disable x86 compat mode for a while: we have to provide native types there thus will back once everything else is complete. Signed-off-by:

- linkage.h points to CRIU's asm specific - prologue.h is just a link to x86, we will need to fix it when start using std with other plugins Signed-off-by:

As it's a make/build option, the set of files to compile depends on it. We don't do feature tests on mrproper/clean (no point in it). Let's define CONFIG_COMPAT for those targets, so compiled files will be properly cleaned. Reported-by:

As -lsoccr now is in $(LIBS) in Makefile.packages, it should be build before criu objects. Otherwise, we try to compile feature-tests with $(LIBS) and the succesful features fails with: <stdin>:1:25: warning: extra tokens at end of #include directive /usr/bin/ld: cannot find -lsoccr collect2: error: ld returned 1 exit status Which lead to later problems: criu/sk-tcp.c:50:8: error: redefinition of 'struct tcp_repair_opt' struct tcp_repair_opt { ^ In file included from criu/sk-tcp.c:1:0: /usr/include/netinet/tcp.h:259:8: note: originally defined here struct tcp_repair_opt Because of fails in really-sucessful feture-tests. P.S. Maybe we should unbound feature-tests compilation from $(LIBS), specified in Makefile.packages - that looks right after all.

compel-host is needed to build criu itself and run during piegen blob generation. Signed-off-by:
-
Cyrill Gorcunov authored
The default compel binary is the one compiled for target architecture. The compel-host one is compel compiled for current arch that is needed to build something for target arch. We could use default compel if target arch == current arch, but this makes things more complex. Signed-off-by:

Delete plugins/include/asm/std directory - let it be without plugin name. Make symlinks to reuse criu's files, except those, which will be deleted after libcompel from criu (like syscalls). Signed-off-by:

The plugin provides basic features as string copying, syscalls, printing. Not used on its own by now but will be shipping by default with other plugins. With great help from Dmitry Safonov. Signed-off-by:

Here we rather suffle source code into directories preparing ground for future work. Basically all this files movements should end up in the following compel/ tree structure compel/ ├── arch │ ├── aarch64 │ │ ├── plugins │ │ │ └── std │ │ └── src │ │ └── lib │ ├── arm ... │ ├── ppc64 ... │ └── x86 ... This is architectural part, where each arch consists of plugins/, and src/. src/ stands for code needed by compel cli + lib ├── include │ ├── compiler.h -> ../../criu/include/compiler.h │ ├── elf32-types.h │ ├── elf64-types.h │ ├── int.h -> ../../criu/include/asm-generic/int.h │ ├── piegen.h │ ├── shmem.h │ └── uapi │ ├── compel.h │ └── plugins.h Common includes + uapi ├── plugins │ ├── fds │ ├── shmem │ └── std Plugins source code └── src ├── lib │ ├── handle-elf-32.c -> handle-elf.c │ ├── handle-elf-32-host.c -> handle-elf-32.c │ ├── handle-elf.c │ └── handle-elf-host.c -> handle-elf.c compel library ├── main.c ├── main-host.c -> main.c compel cli └── shared └── fds.c shared code between plugins and compel cli Note: cross-compile won't work for a while.

As we meet this before, I think, we should abort generation here. No point for making PIE with external symbols for us (at least, yet), so let's break build than find the problem at runtime. Cc: Cyrill Gorcunov <gorcunov@openvz.org> Signed-off-by:

It's used in restorer to map compatible vDSO blob. When !CONFIG_COMPAT it's not needed and even more: vdso_fill_symtable_compat is macro and is undefined in that case. It will never shoot, as compat_vdso is always false for that case, but get rid of it. I also need to leave CONFIG_X86_64 here, as arch_prctl() is not defined for x86_32.

The other way to solve this is to compile shared between CRIU and PIEs objects twice: without stack-protection and with environment choice. But I don't think it worth it. Cc: Cyrill Gorcunov <gorcunov@openvz.org> Signed-off-by:

Dmitry Safonov authored
I think, we could transpher also `-m elf_i386' and `-m32' to compel output - but only in case if we will not support native x86_32 in compel (as they are wrong for native build). Or introduce something like compat_ia32 in compel option, not sure. Left in makefile for a while. Also it would be good to remove $(LD_R) in makefile and use compel output for ldflags, but that will be valid only when compel will support arm arch. Fixes (with the following patches): GEN criu/pie/parasite-compat-blob.h parasite_compat_blob: Error (compel/handle-elf-32.c:322): Unexpected undefined symbol: `__stack_chk_fail'. External symbol in PIE? Cc: Cyrill Gorcunov <gorcunov@openvz.org> Signed-off-by:
