tools: ynl: fix setting presence bits in simple nests

[ Upstream commit f6c8f5e8694c7a78c94e408b628afa6255cc428a ]

When we set members of simple nested structures in requests
we need to set "presence" bits for all the nesting layers
below. This has nothing to do with the presence type of
the last layer.

Protocols:

- Implement support for TCP probing the peer being under memory
pressure

- Remove hard coded limitation on IPv6 specific info placement inside
the socket struct

- Get rid of sysctl_tcp_adv_win_scale and use an auto-estimated per
socket scaling factor

- Scaling-up the IPv6 expired route GC via a separated list of
expiring routes

- In-kernel support for the TLS alert protocol

max connections per lgr negotiation, max links per lgr negotiation

BPF:

- Multi-buffer support in AF_XDP

probes, which is significantly faster and saves extra fds

- Implement an fd-based tc BPF attach API (TCX) and BPF link support
on top of it

- Add SO_REUSEPORT support for TC bpf_sk_assign

- Support new instructions from cpu v4 to simplify the generated code
and feature completeness, for x86, arm64, riscv64

- Support defragmenting IPv(4|6) packets in BPF

- Teach verifier actual bounds of bpf_get_smp_processor_id() and fix
perf+libbpf issue related to custom section handling

- Introduce bpf map element count and enable it for all program types

- Add a BPF hook in sys_socket() to change the protocol ID from
IPPROTO_TCP to IPPROTO_MPTCP to cover migration for legacy

- Introduce bpf_me_mcache_free_rcu() and fix OOM under stress

- Add uprobe support for the bpf_get_func_ip helper

- Check skb ownership against full socket

- Support for up to 12 arguments in BPF trampoline

- Extend link_info for kprobe_multi and perf_event links

Netfilter:

- Speed-up process exit by aborting ruleset validation if a fatal
signal is pending

- Allow NLA_POLICY_MASK to be used with BE16/BE32 types

Driver API:

- Page pool optimizations, to improve data locality and cache usage

- Introduce ndo_hwtstamp_get() and ndo_hwtstamp_set() to avoid the
need for raw ioctl() handling in drivers

- Simplify genetlink dump operations (doit/dumpit) providing them the
common information already populated in struct genl_info

- Extend and use the yaml devlink specs to [re]generate the split ops

- Introduce devlink selective dumps, to allow SF filtering SF based
on handle and other attributes

- Add yaml netlink spec for netlink-raw families, allow route, link
and address related queries via the ynl tool

tools: ynl-gen: fix uAPI generation after tempfile changes

We use a tempfile for code generation, to avoid wiping the target
file out if the code generator crashes. File contents are copied
from tempfile to actual destination at the end of main().

uAPI generation is relatively simple so when generating the uAPI
header we return from main() early, and never reach the "copy code
over" stage. Since commit under Fixes uAPI headers are not updated
by ynl-gen.

Move the copy/commit of the code into CodeWriter, to make it
easier to call at any point in time. Hook it into the destructor
to make sure we don't miss calling it.

We look for attributes inside do.request, but there's another

This bug had no effect as all global policies we generate (fou)
seem to be full, anyway, and we treat full and empty the same.

Next patch will change the treatment of empty policies.

tools: ynl-gen: use temporary file for rendering

Currently any error during render leads to output an empty file.
That is quite annoying when using tools/net/ynl/ynl-regen.sh
which git greps files with content of "YNL-GEN.." and therefore ignores
empty files. So once you fail to regen, you have to checkout the file.

Avoid that by rendering to a temporary file first, only at the end
copy the content to the actual destination.
