c0ae03588b ethtool: rss: initial RSS_SET (indirection table handling)
Add initial support for RSS_SET, for now only operations on
the indirection table are supported.

Unlike the ioctl don't check if at least one parameter is
being changed. This is how other ethtool-nl ops behave,
so pick the ethtool-nl consistency vs copying ioctl behavior.

There are two special cases here:
 1) resetting the table to defaults;
 2) support for tables of different size.

For (1) I use an empty Netlink attribute (array of size 0).

(2) may require some background. AFAICT a lot of modern devices
allow allocating RSS tables of different sizes. mlx5 can upsize
its tables, bnxt has some "table size calculation", and Intel
folks asked about RSS table sizing in context of resource allocation
in the past. The ethtool IOCTL API has a concept of table size,
but right now the user is expected to provide a table exactly
the size the device requests. Some drivers may change the table
size at runtime (in response to queue count changes) but the
user is not in control of this. What's not great is that all
RSS contexts share the same table size. For example a device
with 128 queues enabled, 16 RSS contexts 8 queues in each will
likely have 256 entry tables for each of the 16 contexts,
while 32 would be more than enough given each context only has
8 queues. To address this the Netlink API should avoid enforcing
table size at the uAPI level, and should allow the user to express
the min table size they expect.

To fully solve (2) we will need more driver plumbing but
at the uAPI level this patch allows the user to specify
a table size smaller than what the device advertises. The device
table size must be a multiple of the user requested table size.
We then replicate the user-provided table to fill the full device
size table. This addresses the "allow the user to express the min
table size" objective, while not enforcing any fixed size.
From Netlink perspective .get_rxfh_indir_size() is now de facto
the "max" table size supported by the device.

We may choose to support table replication in ethtool, too,
when we actually plumb this thru the device APIs.

Initially I was considering moving full pattern generation
to the kernel (which queues to use, at which frequency and
what min sequence length). I don't think this complexity
would buy us much and most if not all devices have pow-2
table sizes, which simplifies the replication a lot.

6832a9317e Including fixes from Bluetooth, CAN, WiFi and Netfilter.
More code here than I would have liked. That said, better now than
 next week. Nothing particularly scary stands out. The improvement to
 the OpenVPN input validation is a bit large but better get them in
 before the code makes it to a final release. Some of the changes
 we got from sub-trees could have been split better between the fix
 and -next refactoring, IMHO, that has been communicated.
 
 We have one known regression in a TI AM65 board not getting link.
 The investigation is going a bit slow, a number of people are on
 vacation. We'll try to wrap it up, but don't think it should hold
 up the release.
 
 Current release - fix to a fix:
 
  - Bluetooth: L2CAP: fix attempting to adjust outgoing MTU, it broke
    some headphones and speakers
 
 Current release - regressions:
 
  - wifi: ath12k: fix packets received in WBM error ring with REO LUT
    enabled, fix Rx performance regression
 
  - wifi: iwlwifi:
    - fix crash due to a botched indexing conversion
    - mask reserved bits in chan_state_active_bitmap, avoid FW assert()

2fd895842d rxrpc: Fix notification vs call-release vs recvmsg
When a call is released, rxrpc takes the spinlock and removes it from
->recvmsg_q in an effort to prevent racing recvmsg() invocations from
seeing the same call.  Now, rxrpc_recvmsg() only takes the spinlock when
actually removing a call from the queue; it doesn't, however, take it in
the lead up to that when it checks to see if the queue is empty.  It *does*
hold the socket lock, which prevents a recvmsg/recvmsg race - but this
doesn't prevent sendmsg from ending the call because sendmsg() drops the
socket lock and relies on the call->user_mutex.

Fix this by firstly removing the bit in rxrpc_release_call() that dequeues
the released call and, instead, rely on recvmsg() to simply discard
released calls (done in a preceding fix).

Secondly, rxrpc_notify_socket() is abandoned if the call is already marked
as released rather than trying to be clever by setting both pointers in
call->recvmsg_link to NULL to trick list_empty().  This isn't perfect and
can still race, resulting in a released call on the queue, but recvmsg()
will now clean that up.

962fb1f651 rxrpc: Fix recv-recv race of completed call
If a call receives an event (such as incoming data), the call gets placed
on the socket's queue and a thread in recvmsg can be awakened to go and
process it.  Once the thread has picked up the call off of the queue,
further events will cause it to be requeued, and once the socket lock is
dropped (recvmsg uses call->user_mutex to allow the socket to be used in
parallel), a second thread can come in and its recvmsg can pop the call off
the socket queue again.

In such a case, the first thread will be receiving stuff from the call and
the second thread will be blocked on call->user_mutex.  The first thread
can, at this point, process both the event that it picked call for and the
event that the second thread picked the call for and may see the call
terminate - in which case the call will be "released", decoupling the call
from the user call ID assigned to it (RXRPC_USER_CALL_ID in the control
message).

The first thread will return okay, but then the second thread will wake up
holding the user_mutex and, if it sees that the call has been released by
the first thread, it will BUG thusly:

	kernel BUG at net/rxrpc/recvmsg.c:474!

Fix this by just dequeuing the call and ignoring it if it is seen to be
already released.  We can't tell userspace about it anyway as the user call
ID has become stale.

Add RDMA support for Intel IPU E2000 in idpf

Tatyana Nikolova says:

This idpf patch series is the second part of the staged submission for
introducing RDMA RoCEv2 support for the IPU E2000 line of products,
referred to as GEN3.

To support RDMA GEN3 devices, the idpf driver uses common definitions
of the IIDC interface and implements specific device functionality in
iidc_rdma_idpf.h.

The IPU model can host one or more logical network endpoints called
vPorts per PCI function that are flexibly associated with a physical
port or an internal communication port.

Other features as it pertains to GEN3 devices include:
* MMIO learning
* RDMA capability negotiation
* RDMA vectors discovery between idpf and control plane

These patches are split from the submission "Add RDMA support for Intel
IPU E2000 (GEN3)" [1]. The patches have been tested on a range of hosts
and platforms with a variety of general RDMA applications which include
standalone verbs (rping, perftest, etc.), storage and HPC applications.

2d72afb340 netfilter: nf_conntrack: fix crash due to removal of uninitialised entry
A crash in conntrack was reported while trying to unlink the conntrack
entry from the hash bucket list:
    [exception RIP: __nf_ct_delete_from_lists+172]
    [..]
 #7 [ff539b5a2b043aa0] nf_ct_delete at ffffffffc124d421 [nf_conntrack]
 #8 [ff539b5a2b043ad0] nf_ct_gc_expired at ffffffffc124d999 [nf_conntrack]
 #9 [ff539b5a2b043ae0] __nf_conntrack_find_get at ffffffffc124efbc [nf_conntrack]
    [..]

The nf_conn struct is marked as allocated from slab but appears to be in
a partially initialised state:

 ct hlist pointer is garbage; looks like the ct hash value
 (hence crash).
 ct->status is equal to IPS_CONFIRMED|IPS_DYING, which is expected
 ct->timeout is 30000 (=30s), which is unexpected.

Everything else looks like normal udp conntrack entry.  If we ignore
ct->status and pretend its 0, the entry matches those that are newly
allocated but not yet inserted into the hash:
  - ct hlist pointers are overloaded and store/cache the raw tuple hash
  - ct->timeout matches the relative time expected for a new udp flow
    rather than the absolute 'jiffies' value.

If it were not for the presence of IPS_CONFIRMED,
__nf_conntrack_find_get() would have skipped the entry.

Theory is that we did hit following race:

cpu x 			cpu y			cpu z
 found entry E		found entry E
 E is expired		<preemption>
 nf_ct_delete()
 return E to rcu slab
					init_conntrack
					E is re-inited,
					ct->status set to 0
					reply tuplehash hnnode.pprev
					stores hash value.

cpu y found E right before it was deleted on cpu x.
E is now re-inited on cpu z.  cpu y was preempted before
checking for expiry and/or confirm bit.

					->refcnt set to 1
					E now owned by skb
					->timeout set to 30000

If cpu y were to resume now, it would observe E as
expired but would skip E due to missing CONFIRMED bit.

					nf_conntrack_confirm gets called
					sets: ct->status |= CONFIRMED
					This is wrong: E is not yet added
					to hashtable.

cpu y resumes, it observes E as expired but CONFIRMED:
			<resumes>
			nf_ct_expired()
			 -> yes (ct->timeout is 30s)
			confirmed bit set.

cpu y will try to delete E from the hashtable:
			nf_ct_delete() -> set DYING bit
			__nf_ct_delete_from_lists

Even this scenario doesn't guarantee a crash:
cpu z still holds the table bucket lock(s) so y blocks:

			wait for spinlock held by z

					CONFIRMED is set but there is no
					guarantee ct will be added to hash:
					"chaintoolong" or "clash resolution"
					logic both skip the insert step.
					reply hnnode.pprev still stores the
					hash value.

					unlocks spinlock
					return NF_DROP
			<unblocks, then
			 crashes on hlist_nulls_del_rcu pprev>

In case CPU z does insert the entry into the hashtable, cpu y will unlink
E again right away but no crash occurs.

Without 'cpu y' race, 'garbage' hlist is of no consequence:
ct refcnt remains at 1, eventually skb will be free'd and E gets
destroyed via: nf_conntrack_put -> nf_conntrack_destroy -> nf_ct_destroy.

To resolve this, move the IPS_CONFIRMED assignment after the table
insertion but before the unlock.

Pablo points out that the confirm-bit-store could be reordered to happen
before hlist add resp. the timeout fixup, so switch to set_bit and
before_atomic memory barrier to prevent this.

It doesn't matter if other CPUs can observe a newly inserted entry right
before the CONFIRMED bit was set:

Such event cannot be distinguished from above "E is the old incarnation"
case: the entry will be skipped.

Also change nf_ct_should_gc() to first check the confirmed bit.

The gc sequence is:
 1. Check if entry has expired, if not skip to next entry
 2. Obtain a reference to the expired entry.
 3. Call nf_ct_should_gc() to double-check step 1.

nf_ct_should_gc() is thus called only for entries that already failed an
expiry check. After this patch, once the confirmed bit check passes
ct->timeout has been altered to reflect the absolute 'best before' date
instead of a relative time.  Step 3 will therefore not remove the entry.

Without this change to nf_ct_should_gc() we could still get this sequence:

 1. Check if entry has expired.
 2. Obtain a reference.
 3. Call nf_ct_should_gc() to double-check step 1:
    4 - entry is still observed as expired
    5 - meanwhile, ct->timeout is corrected to absolute value on other CPU
      and confirm bit gets set
    6 - confirm bit is seen
    7 - valid entry is removed again

First do check 6), then 4) so the gc expiry check always picks up either
confirmed bit unset (entry gets skipped) or expiry re-check failure for
re-inited conntrack objects.

This change cannot be backported to releases before 5.19. Without
commit 8a75a2c174 ("netfilter: conntrack: remove unconfirmed list")
|= IPS_CONFIRMED line cannot be moved without further changes.

3549eb08e5 net: mctp: Allow limiting binds to a peer address
Prior to calling bind() a program may call connect() on a socket to
restrict to a remote peer address.

Using connect() is the normal mechanism to specify a remote network
peer, so we use that here. In MCTP connect() is only used for bound
sockets - send() is not available for MCTP since a tag must be provided
for each message.

The smctp_type must match between connect() and bind() calls.

444020f4bf wifi: cfg80211: remove scan request n_channels counted_by
This reverts commit e3eac9f32e ("wifi: cfg80211: Annotate struct
cfg80211_scan_request with __counted_by").

This really has been a completely failed experiment. There were
no actual bugs found, and yet at this point we already have four
"fixes" to it, with nothing to show for but code churn, and it
never even made the code any safer.

In all of the cases that ended up getting "fixed", the structure
is also internally inconsistent after the n_channels setting as
the channel list isn't actually filled yet. You cannot scan with
such a structure, that's just wrong. In mac80211, the struct is
also reused multiple times, so initializing it once is no good.

Some previous "fixes" (e.g. one in brcm80211) are also just setting
n_channels before accessing the array, under the assumption that the
code is correct and the array can be accessed, further showing that
the whole thing is just pointless when the allocation count and use
count are not separate.

If we really wanted to fix it, we'd need to separately track the
number of channels allocated and the number of channels currently
used, but given that no bugs were found despite the numerous syzbot
reports, that'd just be a waste of time.

Remove the __counted_by() annotation. We really should also remove
a number of the n_channels settings that are setting up a structure
that's inconsistent, but that can wait.

with netdev_ prefix to match other newer APIs.

Note that we always use GFP_ATOMIC for netdev_hold() as it's expected
to be called under RCU.

6aa53e861c idpf: implement get LAN MMIO memory regions
The RDMA driver needs to map its own MMIO regions for the sake of
performance, meaning the IDPF needs to avoid mapping portions of the BAR
space. However, to be HW agnostic, the IDPF cannot assume where
these are and must avoid mapping hard coded regions as much as possible.

The IDPF maps the bare minimum to load and communicate with the
control plane, i.e., the mailbox registers and the reset state
registers. Because of how and when mailbox register offsets are
initialized, it is easier to adjust the existing defines to be relative
to the mailbox region starting address. Use a specific mailbox register
write function that uses these relative offsets. The reset state
register addresses are calculated the same way as for other registers,
described below.

The IDPF then calls a new virtchnl op to fetch a list of MMIO regions
that it should map. The addresses for the registers in these regions are
calculated by determining what region the register resides in, adjusting
the offset to be relative to that region, and then adding the
register's offset to that region's mapped address.

If the new virtchnl op is not supported, the IDPF will fallback to
mapping the whole bar. However, it will still map them as separate
regions outside the mailbox and reset state registers. This way we can
use the same logic in both cases to access the MMIO space.

be91128c57 idpf: implement RDMA vport auxiliary dev create, init, and destroy
Implement the functions to create, initialize, and destroy an RDMA vport
auxiliary device. The vport aux dev creation is dependent on the
core aux device to call idpf_idc_vport_dev_ctrl to signal that it is
ready for vport aux devices. Implement that core callback to either
create and initialize the vport aux dev or deinitialize.

RDMA vport aux dev creation is also dependent on the control plane to
tell us the vport is RDMA enabled. Add a flag in the create vport
message to signal individual vport RDMA capabilities.

f4312e6bfa idpf: implement core RDMA auxiliary dev create, init, and destroy
Add the initial idpf_idc.c file with the functions to kick off the IDC
initialization, create and initialize a core RDMA auxiliary device, and
destroy said device.

The RDMA core has a dependency on the vports being created by the
control plane before it can be initialized. Therefore, once all the
vports are up after a hard reset (either during driver load a function
level reset), the core RDMA device info will be created. It is populated
with the function type (as distinguished by the IDC initialization
function pointer), the core idc_ops function points (just stubs for
now), the reserved RDMA MSIX table, and various other info the core RDMA
auxiliary driver will need. It is then plugged on to the bus.

During a function level reset or driver unload, the device will be
unplugged from the bus and destroyed.

c4f96972c3 RDMA/mlx5: Fix UMR modifying of mkey page size
When changing the page size on an mkey, the driver needs to set the
appropriate bits in the mkey mask to indicate which fields are being
modified.
The 6th bit of a page size in mlx5 driver is considered an extension,
and this bit has a dedicated capability and mask bits.

Previously, the driver was not setting this mask in the mkey mask when
performing page size changes, regardless of its hardware support,
potentially leading to an incorrect page size updates.

This fixes the issue by setting the relevant bit in the mkey mask when
performing page size changes on an mkey and the 6th bit of this field is
supported by the hardware.
