A few controllers can be merged and before this patch, criu required to set a new root by specifying all merged controllers. This patch allows to specify a new root for each controller separately, but criu will check that all merged controllers will have the same path. https://github.com/checkpoint-restore/criu/issues/544Signed-off-by:

F_GETLK64 has to be used with flock64 Reported-by: Mr Jenkins

If we want to use flock64, we have to use fcntl64. Otherwise we will get errors like this: ERR: file_locks07.c:49: Can't set ofd lock (errno = 22 (Invalid argument)) Reported-by: Mr Jenkins Signed-off-by: -

Kernel will send signal with ABI of *syscall* that made rt_sigacation(). In sigaction_compat_abi(): > if (in_ia32_syscall()) > act->sa.sa_flags |= SA_IA32_ABI; So, we can omit switching to ia32 mode and just call int80 like in other places. We still need 32-bit argument for syscall (sig action pointer). As call32_from_64() switches mode, it's .text should be placed in lower 4Gb, which was the reason of segfault if linker places criu code above 4Gb. Oops, my bad. Fixes: #567 Reported-by:

%ebx, %ecx aren't specified as clobbers in chk_proc_fpu(), while asm cpuid overwrites them. In the turn, %ebx is used as a code position by gcc now: 1661: e8 9a 00 00 00 call 1700 <__x86.get_pc_thunk.bx> 1666: 81 c3 46 68 00 00 add $0x6846,%ebx Which results in dereferencing some ugly garbage (result of cpuid). Let's use zdtm/lib cpuid() function instead. Signed-off-by:

When restoring a task in it's user namespace we had: "Unable to open pages-3.img: Permission denied" when trying to open pages images for write. (Write is needed for memory images deduplication feature to work.) These patch makes do_open_image open images fd through usernsd, to have root permissions. Also increase MAX_UNSFD_MSG_SIZE as path and metadata don't fit, and remove a workaround in prepare_vma_ios. Signed-off-by:

Currently, we create only one external resource to check how it is handled by criu. It is better to create more than one. Signed-off-by:

CPython currently uses a reference-counting scheme with (optional) delayed detection of cyclically linked garbage, which collects most objects as soon as they become unreachable, but is not guaranteed to collect garbage containing circular references. Some objects contain references to "external" resources such as open files. It is understood that these resources are freed when the object is garbage-collected, but since garbage collection is not guaranteed to happen, such objects also provide an explicit way to release the external resource, usually a close() method. Programs are strongly recommended to explicitly close such objects. Reference: https://docs.python.org/3.6/reference/datamodel.htmlSigned-off-by:
