Newer Intel CPUs (Sapphire Rapids) have a much larger xsave area than
before. Looking at older CPUs I see 2440 bytes.
# cpuid -1 -l 0xd -s 0
...
bytes required by XSAVE/XRSTOR area = 0x00000988 (2440)
On newer CPUs (Sapphire Rapids) it grows to 11008 bytes.
# cpuid -1 -l 0xd -s 0
...
bytes required by XSAVE/XRSTOR area = 0x00002b00 (11008)
This increase the xsave area from one page to four pages.
Without this patch the fpu03 test fails, with this patch it works again.

Using the fact that we know criu_pid and criu is a parent of restored process we can create pidfile with pid on caller pidns level. We need to move mount namespace creation to child so that criu-ns can see caller pidns proc. Signed-off-by: Pavel Tikhomirov <ptikhomirov@virtuozzo.com>
By default, the file name 'amdgpu_plugin.txt' is used also as the name for the corresponding man page (`man amdgpu_plugin`). However, when this man page is installed system-wide it would be more appropriate to have a prefix 'criu-' (e.g., `man criu-amdgpu-plugin`).

This is a patch proposed by Thomas here: https://lore.kernel.org/all/87ilczc7d9.ffs@tglx/ It removes (created id > desired id) "sanity" check and adds proper checking that ids start at zero and increment by one each time when we create/delete a posix timer. First purpose of it is to fix infinite looping in create_posix_timers on old pre 3.11 kernels. Second purpose is to allow kernel interface of creating posix timers with desired id change from iterating with predictable next id to just setting next id directly. And at the same time removing predictable next id so that criu with this patch would not get to infinite loop in create_posix_timers if this happens. Thanks a lot to Thomas!

…tions This does cgroup namespace creation separately from joining task cgroups. This makes the code more logical, because creating cgroup namespace also involves joining cgroups but these cgroups can be different to task's cgroups as they are cgroup namespace roots (cgns_prefix), and mixing all of them together may lead to misunderstanding. Another positive thing is that we consolidate !item->parent checks in one place in restore_task_with_children.

Newer versions of pip use an isolated virtual environment when building Python projects. However, when the source code of CRIT is copied into the isolated environment, the symlink for `../lib/py` (pycriu) becomes invalid. As a workaround, we used the `--no-build-isolation` option for `pip install`. However, this functionality has issues in some versions of PIP [1, 2]. To fix this problem, this patch adds separate packages for pycriu and crit, and each package is installed independently.

If ioctl(TIOCSLCKTRMIOS) fails with EPERM it means that a CRIU process lacks of CAP_SYS_ADMIN capability. But we can use ioctl(TIOCGLCKTRMIOS) to *read* current ->termios_locked value from the kernel and if it's the same as we already have we can skip failing ioctl(TIOCSLCKTRMIOS) safely. Adrian has recently posted [1] a very good patch to allow ioctl(TIOCSLCKTRMIOS) for processes that have CAP_CHECKPOINT_RESTORE (right now it requires CAP_SYS_ADMIN).

In commit [1] was introduced a mechanism to auto-generate the files: sys-exec-tbl*.c, syscalls*.S, syscall-codes*.h, and syscall*.h. This commit also updated the gitignore rules to ignore auto-generated files. However, after commit [2], the path for these files has changed and the patterns specified in gitignore are no longer needed.
