If the AP removal timer is long, we don't really want to
remove the link immediately. However, we really should do
it _before_ the AP removes it (which happens at or after
count reaches 0), so subtract 1 from the countdown when
scheduling the timer. This causes the link removal work
to run just after the beacon with value 1 is received. If
the counter is already zero, do it immediately.
This fixes an issue where we do the removal too late and
receive a beacon from the AP that's no longer associated
with the MLD, but thus removed EHT and ML elements, and
then we disconnect instead from the whole MLD, since one
of the associated APs changed mode from EHT to HE.

If the AP mode ends up being determined less than the client mode,
there may be different reasons for this, e.g. AP misconfiguration.
If this happens in a way that causes e.g. EHT to be rejected, the
elements need to be re-parsed since we'll connect as HE, but not
reparsing means that we'll still think it's OK to use multi-link,
so we can connect in a non-sensical configuration of advertising
only HE on a secondary link. This normally won't happen for the
assoc link because that reuses the mode from authentication, and
if that's not EHT, multi-link association is rejected.
Fix this inconsistency by parsing the elements again if the mode
was different from the first parsing attempt. Print the message a
bit later to avoid printing "determined AP ... to be HE" twice in
cases where ieee80211_determine_ap_chan() returned a lesser mode,
rather than the regulatory downgrades below changing it.

ip_local_out() and other functions can pass skb->sk as function argument.
If the skb is a fragment and reassembly happens before such function call
returns, the sk must not be released.
This affects skb fragments reassembled via netfilter or similar
modules, e.g. openvswitch or ct_act.c, when run as part of tx pipeline.
Eric Dumazet made an initial analysis of this bug. Quoting Eric:
Calling ip_defrag() in output path is also implying skb_orphan(),
which is buggy because output path relies on sk not disappearing.
A relevant old patch about the issue was :
8282f27449 ("inet: frag: Always orphan skbs inside ip_defrag()")
[..]
net/ipv4/ip_output.c depends on skb->sk being set, and probably to an
inet socket, not an arbitrary one.
If we orphan the packet in ipvlan, then downstream things like FQ
packet scheduler will not work properly.
We need to change ip_defrag() to only use skb_orphan() when really
needed, ie whenever frag_list is going to be used.
Eric suggested to stash sk in fragment queue and made an initial patch.
However there is a problem with this:
If skb is refragmented again right after, ip_do_fragment() will copy
head->sk to the new fragments, and sets up destructor to sock_wfree.
IOW, we have no choice but to fix up sk_wmem accouting to reflect the
fully reassembled skb, else wmem will underflow.
This change moves the orphan down into the core, to last possible moment.
As ip_defrag_offset is aliased with sk_buff->sk member, we must move the
offset into the FRAG_CB, else skb->sk gets clobbered.
This allows to delay the orphaning long enough to learn if the skb has
to be queued or if the skb is completing the reasm queue.
In the former case, things work as before, skb is orphaned. This is
safe because skb gets queued/stolen and won't continue past reasm engine.
In the latter case, we will steal the skb->sk reference, reattach it to
the head skb, and fix up wmem accouting when inet_frag inflates truesize.

Skip hook unregistration when adding or deleting devices from an
existing netdev basechain. Otherwise, commit/abort path try to
unregister hooks which not enabled.
Fixes: b9703ed44f ("netfilter: nf_tables: support for adding new devices to an existing netdev chain")

netdev basechain updates are stored in the transaction object hook list.
When setting on the table dormant flag, it iterates over the existing
hooks in the basechain. Thus, skipping the hooks that are being
added/deleted in this transaction, which leaves hook registration in
inconsistent state.
Reject table flag updates in combination with netdev basechain updates
in the same batch:
- Update table flags and add/delete basechain: Check from basechain update
path if there are pending flag updates for this table.
- add/delete basechain and update table flags: Iterate over the transaction
list to search for basechain updates from the table update path.
In both cases, the batch is rejected. Based on suggestion from Florian Westphal.

This patch re-introduces protection against the size of access to stack
memory being negative; the access size can appear negative as a result
of overflowing its signed int representation. This should not actually
happen, as there are other protections along the way, but we should
protect against it anyway. One code path was missing such protections
(fixed in the previous patch in the series), causing out-of-bounds array
accesses in check_stack_range_initialized(). This patch causes the
verification of a program with such a non-sensical access size to fail.
This check used to exist in a more indirect way, but was inadvertendly
removed in a833a17aea.

This patch adds a missing check to bloom filter creating, rejecting
values above KMALLOC_MAX_SIZE. This brings the bloom map in line with
many other map types.
The lack of this protection can cause kernel crashes for value sizes
that overflow int's. Such a crash was caught by syzkaller. The next
patch adds more guard-rails at a lower level.

Commit 576882ef5e ("uio: introduce UIO_MEM_DMA_COHERENT type")
introduced a new use-case for 'struct uio_mem' where the 'mem' field now
contains a kernel virtual address when 'memtype' is set to
UIO_MEM_DMA_COHERENT.
That in turn causes build errors, because 'mem' is of type
'phys_addr_t', and a virtual address is a pointer type. When the code
just blindly uses cast to mix the two, it caused problems when
phys_addr_t isn't the same size as a pointer - notably on 32-bit
architectures with PHYS_ADDR_T_64BIT.
The proper thing to do would probably be to use a union member, and not
have any casts, and make the 'mem' member be a union of 'mem.physaddr'
and 'mem.vaddr', based on 'memtype'.
This is not that proper thing. This is just fixing the ugly casts to be
even uglier, but at least not cause build errors on 32-bit platforms
with 64-bit physical addresses.

The longest running netdevsim test, nexthop.sh, currently takes
5 min to finish. Around 260s to be exact, and 310s on a debug kernel.
The default timeout in selftest is 45sec, so we need an explicit
config. Give ourselves some headroom and use 10min.
Commit under Fixes isn't really to "blame" but prior to that
netdevsim tests weren't integrated with kselftest infra
so blaming the tests themselves doesn't seem right, either.
Fixes: 8ff25dac88 ("netdevsim: add Makefile for selftests")

tls: recvmsg fixes
The first two fixes are again related to async decrypt. The last one
is unrelated but I stumbled upon it while reading the code.

At the start of tls_sw_recvmsg, we take a reference on the psock, and
then call tls_rx_reader_lock. If that fails, we return directly
without releasing the reference.
Instead of adding a new label, just take the reference after locking
has succeeded, since we don't need it before.
