During devlink port init/cleanup and register/unregister calls, there
are many lookups of vport. Instead of passing vport_num as argument to
functions, pass the vport struct pointer directly and avoid repeated
lookups.

Struct devlink_port is usually embedded in a driver-specific struct
which allows to carry driver context to devlink port ops.
Introduce a container struct to include devlink_port struct
in preparation to also include driver context for devlink port ops.

Currently each PF/VF/SF devlink port op called into mlx5 code calls
is_port_function_supported() to check if the port is either
PF, VF or SF. So make sure that the ops are registered with devlink
port only for those and avoid the is_port_function_supported() checks
in ops.

====================
mptcp: Prepare MPTCP packet scheduler for BPF extension
The kernel's MPTCP packet scheduler has, to date, been a one-size-fits
all algorithm that is hard-coded. It attempts to balance latency and
throughput when transmitting data across multiple TCP subflows, and has
some limited tunability through sysctls. It has been a long-term goal of
the Linux MPTCP community to support customizable packet schedulers for
use cases that need to make different trade-offs regarding latency,
throughput, redundancy, and other metrics. BPF is well-suited for
configuring customized, per-packet scheduling decisions without having
to modify the kernel or manage out-of-tree kernel modules.
The first steps toward implementing BPF packet schedulers are to update
the existing MPTCP transmit loops to allow more flexible scheduling
decisions, and to add infrastructure for swappable packet schedulers.
The existing scheduling algorithm remains the default. BPF-related
changes will be in a future patch series.
This code has been in the MPTCP development tree for quite a while,
undergoing testing in our CI and community.
Patches 1 and 2 refactor the transmit code and do some related cleanup.
Patches 3-9 add infrastructure for registering and calling multiple
schedulers.
Patch 10 connects the in-kernel default scheduler to the new
infrastructure.

While first_pending isn't empty:

The automatic recalculation of the maximum allowed MTU is usually triggered
by code sections which are already rtnl lock protected by callers outside
of batman-adv. But when the fragmentation setting is changed via
batman-adv's own batadv genl family, then the rtnl lock is not yet taken.
But dev_set_mtu requires that the caller holds the rtnl lock because it
uses netdevice notifiers. And this code will then fail the check for this
lock:

The original implementation had a very simple handling for single frame
transmissions as it just sent the single frame without a timeout handling.
With the new echo frame handling the echo frame was also introduced for
single frames but the former exception ('simple without timers') has been
maintained by accident. This leads to a 1 second timeout when closing the
socket and to an -ECOMM error when CAN_ISOTP_WAIT_TX_DONE is selected.
As the echo handling is always active (also for single frames) remove the
wrong extra condition for single frames.

While injecting PCIe errors to the upstream PCIe switch of
a BCM57810 NIC, system hangs/crashes were observed.
After several calls to bnx2x_tx_timout() complete,
bnx2x_nic_unload() is called to free up HW resources
and bnx2x_napi_disable() is called to release NAPI objects.
Later, when the EEH driver calls bnx2x_io_slot_reset() to
complete the recovery process, bnx2x attempts to disable
NAPI again by calling bnx2x_napi_disable() and freeing
resources which have already been freed, resulting in a
hang or crash.
Introduce a new flag to track the HW resource and NAPI
allocation state, refactor duplicated code into a single
function, check page pool allocation status before freeing,
and reduces debug output when a TX timeout event occurs.

I hit a memory leak when testing bpf_program__set_attach_target().
Basically, set_attach_target() may allocate btf_vmlinux, for example,
when setting attach target for bpf_iter programs. But btf_vmlinux
is freed only in bpf_object_load(), which means if we only open
bpf object but not load it, setting attach target may leak
btf_vmlinux.
So let's free btf_vmlinux in bpf_object__close() anyway.

The commit being fixed introduced a hunk into check_func_arg_reg_off
that bypasses reg->off == 0 enforcement when offset points to a graph
node or root. This might possibly be done for treating bpf_rbtree_remove
and others as KF_RELEASE and then later check correct reg->off in helper
argument checks.
But this is not the case, those helpers are already not KF_RELEASE and
permit non-zero reg->off and verify it later to match the subobject in
BTF type.
However, this logic leads to bpf_obj_drop permitting free of register
arguments with non-zero offset when they point to a graph root or node
within them, which is not ok.
For instance:
struct foo {
int i;
int j;
struct bpf_rb_node node;
};
struct foo *f = bpf_obj_new(typeof(*f));
if (!f) ...
bpf_obj_drop(f); // OK
bpf_obj_drop(&f->i); // still ok from verifier PoV
bpf_obj_drop(&f->node); // Not OK, but permitted right now
Fix this by dropping the whole part of code altogether.

This reverts commit b970ac68e0c4 ("wifi: mac80211_hwsim: check the

the error path, which seems worse than sending an incomplete skb,

While looking at a bug, I got rather confused by the layout of the
'status' field in ieee80211_tx_info. Apparently, the intention is that
status_driver_data[] is used for driver specific data, and fills up the
size of the union to 40 bytes, just like the other ones.
This is indeed what actually happens, but only because of the
combination of two mistakes:
- "void *status_driver_data[18 / sizeof(void *)];" is intended
to be 18 bytes long but is actually two bytes shorter because of
rounding-down in the division, to a multiple of the pointer
size (4 bytes or 8 bytes).
- The other fields combined are intended to be 22 bytes long, but
are actually 24 bytes because of padding in front of the
unaligned tx_time member, and in front of the pointer array.
The two mistakes cancel out. so the size ends up fine, but it seems
more helpful to make this explicit, by having a multiple of 8 bytes
in the size calculation and explicitly describing the padding.

The previous commit dd3e4fc75b4a ("nl80211/cfg80211: add BSS color to
NDP ranging parameters") adds a parameter for NDP ranging by introducing
a new attribute type named NL80211_PMSR_FTM_REQ_ATTR_BSS_COLOR.
However, the author forgot to also describe the nla_policy at
nl80211_pmsr_ftm_req_attr_policy (net/wireless/nl80211.c). Just
complement it to avoid malformed attribute that causes out-of-attribute
access.

While technically some control frames like ACK are shorter and
end after Address 1, such frames shouldn't be forwarded through
wmediumd or similar userspace, so require the full 3-address

When probing a client, first check if we have it, and then
check for the channel context, otherwise you can trigger
the warning there easily by probing when the AP isn't even
started yet. Since a client existing means the AP is also
operating, we can then keep the warning.
Also simplify the moved code a bit.
