cgroup: allow to specify a new root for each controller separately · 44a10467

Andrei Vagin authored Oct 29, 2018

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.

x86/compat: Use do_full_int80() instead of jump to ia32 mode · b0c5881d

Dmitry Safonov authored Oct 30, 2018

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.

zdtm/x86: Don't override %ebx in fpu00 · 2c5e8fd7

Dmitry Safonov authored Oct 31, 2018

%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.

When restoring a task in it's user namespace we had: "Unable to open

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.
