packages needed in a particular project to run it. The most commonly
used way is to store them in the `requirements.txt` file*.

*URL: https://pip.pypa.io/en/stable/reference/requirements-file-format/

Currently user needs to figure out himself that Python needs `PyYAML`
and `jsonschema` (and theirs requirements) packages to use the tool.
Add the `requirements.txt` for user convenience.

How to use it:
1) (optional) Create and activate empty virtual environment:
  python3.X -m venv venv3X
  source ./venv3X/bin/activate
2) Install all the required packages:
  pip install -r requirements.txt
    or
  python -m pip install -r requirements.txt
3) Run the script!

can: m_can: Keep interrupts enabled during peripheral read

Interrupts currently get disabled if the interrupt status shows new
received data. Non-peripheral chips handle receiving in a worker thread,
but peripheral chips are handling the receive process in the threaded
interrupt routine itself without scheduling it for a different worker.

However, we can't just disable ipv6 addrconf for team ports, as 'teamd'

Instead of preventing ipv6 addrconf, this patch only prevents RS packets
for team ports, as it did in commit b52e1cce31ca ("ipv6: Don't send rs

Note that we do not prevent DAD packets, to avoid the changes getting

1. Change IPv6 stack to keep conntrack references until ipsec policy
   checks are done, like ipv4, from Madhu Koriginja.
   This update was missed when IPv6 NAT support was added 10 years ago.

2. get rid of old 'compat' structure layout in nf_nat_redirect
   core and move the conversion to the only user that needs the
   old layout for abi reasons. From Jeremy Sowden.

3. Compact some common code paths in nft_redir, also from Jeremy.

4. Time to remove the 'default y' knob so iptables 32bit compat interface
   isn't compiled in by default anymore, from myself.

5. Move ip(6)tables builtin icmp matches to the udptcp one.
   This has the advantage that icmp/icmpv6 match doesn't load the
   iptables/ip6tables modules anymore when iptables-nft is used.

Bluetooth: HCI: Fix global-out-of-bounds

To loop a variable-length array, hci_init_stage_sync(stage) considers
that stage[i] is valid as long as stage[i-1].func is valid.
Thus, the last element of stage[].func should be intentionally invalid
as hci_init0[], le_init2[], and others did.
However, amp_init1[] and amp_init2[] have no invalid element, letting
hci_init_stage_sync() keep accessing amp_init1[] over its valid range.
This patch fixes this by adding {} in the last of amp_init1[] and
amp_init2[].

Bluetooth: btqcomsmd: Fix command timeout after setting BD address

On most devices using the btqcomsmd driver (e.g. the DragonBoard 410c
and other devices based on the Qualcomm MSM8916/MSM8909/... SoCs)
the Bluetooth firmware seems to become unresponsive for a while after
setting the BD address. On recent kernel versions (at least 5.17+)
this often causes timeouts for subsequent commands, e.g. the HCI reset
sent by the Bluetooth core during initialization:

    Bluetooth: hci0: Opcode 0x c03 failed: -110

Unfortunately this behavior does not seem to be documented anywhere.
Experimentation suggests that the minimum necessary delay to avoid
the problem is ~150us. However, to be sure add a sleep for > 1ms
in case it is a bit longer on other firmware versions.

Older kernel versions are likely also affected, although perhaps with
slightly different errors or less probability. Side effects can easily
hide the issue in most cases, e.g. unrelated incoming interrupts that
cause the necessary delay.

====================
net: Allow changing IPv4 address protocol

IPv4 and IPv6 addresses can be assigned a protocol value that indicates the
provenance of the IP address. The attribute is modeled after ip route
protocols, and essentially allows the administrator or userspace stack to
tag addresses in some way that makes sense to the actor in question.

When IP address protocol field was added in commit 47f0bd503210 ("net: Add
new protocol attribute to IP addresses"), the semantics included the
ability to change the protocol for IPv6 addresses, but not for IPv4
addresses. It seems this was not deliberate, but rather by accident.

One particular use case is tagging the addresses differently depending on
whether the routing stack should advertise them or not. Without support for
protocol replacement, this can not be done.

In this patchset, extend IPv4 to allow changing the protocol defined at an
address (in patch #1). Then in patches #2 and #3 add selftest coverage for
ip address protocols.

Currently the kernel simply ignores the new value. Thus allowing the
replacement changes the observable behavior. However, since IPv6 already
behaves like this anyway, and since the feature as such is relatively new,
it seems like the change is safe to make.

An example session with the feature in action:

bash-5.2# ip address add dev d 192.0.2.1/28 proto 0xab
bash-5.2# ip address show dev d

net: ipv4: Allow changing IPv4 address protocol

When IP address protocol field was added in commit 47f0bd503210 ("net: Add
new protocol attribute to IP addresses"), the semantics included the
ability to change the protocol for IPv6 addresses, but not for IPv4
addresses. It seems this was not deliberate, but rather by accident.

A userspace that wants to change the protocol of an address might drop and
recreate the address, but that disrupts routing and is just impractical.

So in this patch, when an IPv4 address is replaced (through RTM_NEWADDR
request with NLM_F_REPLACE flag), update the proto at the address to the
one given in the request, or zero if none is given. This matches the
behavior of IPv6. Previously, any new value given was simply ignored.
