Pass the len to the compat_ipv6_get_msfilter() instead of
compat_ipv6_get_msfilter() getting it again from optlen.
Its counter part ipv6_get_msfilter() is also taking the
len from do_ipv6_getsockopt().

Similar to the earlier commit that changed sk_setsockopt() to
use sockopt_{lock,release}_sock() such that it can avoid taking
lock when called from bpf. This patch also changes do_ip_getsockopt()
to use sockopt_{lock,release}_sock() such that a latter patch can
make bpf_getsockopt(SOL_IP) to reuse do_ip_getsockopt().

Similar to the earlier patch that changes sk_getsockopt() to
take the sockptr_t argument. This patch also changes
do_ip_getsockopt() to take the sockptr_t argument such that
a latter patch can make bpf_getsockopt(SOL_IP) to reuse
do_ip_getsockopt().
Note on the change in ip_mc_gsfget(). This function is to
return an array of sockaddr_storage in optval. This function
is shared between ip_get_mcast_msfilter() and
compat_ip_get_mcast_msfilter(). However, the sockaddr_storage
is stored at different offset of the optval because of
the difference between group_filter and compat_group_filter.
Thus, a new 'ss_offset' argument is added to ip_mc_gsfget().

to use sockopt_{lock,release}_sock() such that a latter patch can

Only sk_get_filter() requires this change and it is used by

The '.getname' implementations in sock->ops->getname() is not
changed also since bpf does not always have the sk->sk_socket
pointer and cannot support SO_PEERNAME.

This patch changes sk_getsockopt() to take the sockptr_t argument
such that it can be used by bpf_getsockopt(SOL_SOCKET) in a
latter patch.
security_socket_getpeersec_stream() is not changed. It stays
with the __user ptr (optval.user and optlen.user) to avoid changes
to other security hooks. bpf_getsockopt(SOL_SOCKET) also does not
support SO_PEERSEC.

A latter patch refactors bpf_getsockopt(SOL_SOCKET) with the
sock_getsockopt() to avoid code duplication and code
drift between the two duplicates.
The current sock_getsockopt() takes sock ptr as the argument.
The very first thing of this function is to get back the sk ptr
by 'sk = sock->sk'.
bpf_getsockopt() could be called when the sk does not have
the sock ptr created. Meaning sk->sk_socket is NULL. For example,
when a passive tcp connection has just been established but has yet
been accept()-ed. Thus, it cannot use the sock_getsockopt(sk->sk_socket)
or else it will pass a NULL ptr.
This patch moves all sock_getsockopt implementation to the newly
added sk_getsockopt(). The new sk_getsockopt() takes a sk ptr
and immediately gets the sock ptr by 'sock = sk->sk_socket'
The existing sock_getsockopt(sock) is changed to call
sk_getsockopt(sock->sk). All existing callers have both sock->sk
and sk->sk_socket pointer.
The latter patch will make bpf_getsockopt(SOL_SOCKET) call
sk_getsockopt(sk) directly. The bpf_getsockopt(SOL_SOCKET) does
not use the optnames that require sk->sk_socket, so it will
be safe.

Florian Westphal says:
====================
netfilter: bug fixes for net
1. Fix IP address check in irc DCC conntrack helper, this should check
the opposite direction rather than the destination address of the
packets' direction, from David Leadbeater.
2. bridge netfilter needs to drop dst references, from Harsh Modi.
This was fine back in the day the code was originally written,
but nowadays various tunnels can pre-set metadata dsts on packets.
3. Remove nf_conntrack_helper sysctl and the modparam toggle, users
need to explicitily assign the helpers to use via nftables or
iptables. Conntrack helpers, by design, may be used to add dynamic
port redirections to internal machines, so its necessary to restrict
which hosts/peers are allowed to use them.
It was discovered that improper checking in the irc DCC helper makes
it possible to trigger the 'please do dynamic port forward'
from outside by embedding a 'DCC' in a PING request; if the client
echos that back a expectation/port forward gets added.
The auto-assign-for-everything mechanism has been in "please don't do this"
territory since 2012. From Pablo.
4. Fix a memory leak in the netdev hook error unwind path, also from Pablo.

Pull io_uring fixes from Jens Axboe:
- A single fix for over-eager retries for networking (Pavel)
- Revert the notification slot support for zerocopy sends.
It turns out that even after more than a year or development and
testing, there's not full agreement on whether just using plain
ordered notifications is Good Enough to avoid the complexity of using
the notifications slots. Because of that, we decided that it's best
left to a future final decision.
We can always bring back this feature, but we can't really change it
or remove it once we've released 6.0 with it enabled. The reverts
leave the usual CQE notifications as the primary interface for
knowing when data was sent, and when it was acked. (Pavel)

iavf_reset_task() takes crit_lock at the beginning and holds
it during whole call. The function subsequently calls
iavf_init_interrupt_scheme() that grabs RTNL. Problem occurs
when userspace initiates during the reset task any ndo callback
that runs under RTNL like iavf_open() because some of that
functions tries to take crit_lock. This leads to classic A-B B-A
deadlock scenario.
To resolve this situation the device should be detached in
iavf_reset_task() prior taking crit_lock to avoid subsequent
ndos running under RTNL and reattach the device at the end.

Two offline tests cause IRDMA driver failure (ETIMEDOUT) and this
failure is indicated back to i40e_client_subtask() that calls
i40e_client_del_instance() to free client instance referenced
by pf->cinst and sets this pointer to NULL. During the module
removal i40e_remove() calls i40e_lan_del_device() that dereferences
pf->cinst that is NULL -> crash.
Do not remove client instance when client open callbacks fails and
just clear __I40E_CLIENT_INSTANCE_OPENED bit. The driver also needs
to take care about this situation (when netdev is up and client
is NOT opened) in i40e_notify_client_of_netdev_close() and
calls client close callback only when __I40E_CLIENT_INSTANCE_OPENED
is set.

The enet_qos_root_clk takes sim_enet_root_clk as parent. When
registering enet_qos_root_clk, it will be put into clk orphan list,
because sim_enet_root_clk is not ready.
When sim_enet_root_clk is ready, clk_core_reparent_orphans_nolock will
set enet_qos_root_clk parent to sim_enet_root_clk.
Because CLK_OPS_PARENT_ENABLE is set, sim_enet_root_clk will be
enabled and disabled during the enet_qos_root_clk reparent phase.
All the above are correct. But with M7 booted early and using
enet, M7 enet feature will be broken, because clk driver probe phase
disable the needed clks, in case M7 firmware not configure
sim_enet_root_clk.
And tune the order would also save cpu cycles.

Fix HW rate limiting for ADQ.
Fallback to kernel queue selection for ADQ, as it is network stack
that decides which queue to use for transmit with ADQ configured.
Reset PF after creation of VMDq2 VSIs required for ADQ, as to
reprogram TX queue contexts in i40e_configure_tx_ring.
Without this patch PF would limit TX rate only according to TC0.

In perf/Documentation/perf-stat.txt, for "--td-level" the default "0" means
the max level that the current hardware support.
So we need initialize the stat_config.topdown_level to TOPDOWN_MAX_LEVEL
when “--td-level=0” or no “--td-level” option. Otherwise, for the
hardware with a max level is 2, the 2nd level metrics disappear for raw
events in this case.
The issue cannot be observed for the perf stat default or "--topdown"
options. This commit fixes the raw events issue and removes the
duplicated code for the perf stat default.
