When tipc_sk_timeout() is executed but user space is grabbing
ownership, this function rearms itself and returns. However, the
socket reference counter is not reduced. This causes potential
unexpected behavior.
This commit fixes it by calling sock_put() before tipc_sk_timeout()
returns in the above-mentioned case.

When initiating a connection message to a server side, the connection
message is cloned and added to the socket write queue. However, if the
cloning is failed, only the socket write queue is purged. It causes
memory leak because the original connection message is not freed.
This commit fixes it by purging the list of connection message when
it cannot be cloned.

====================
net: tls: fix scatter-gather list issues
This series kicked of by a syzbot report fixes three issues around
scatter gather handling in the TLS code. First patch fixes a use-
-after-free situation which may occur if record was freed on error.
This could have already happened in BPF paths, and patch 2 now makes
the same condition occur in non-BPF code.
Patch 2 fixes the problem spotted by syzbot. If encryption failed
we have to clean the end markings from scatter gather list. As
suggested by John the patch frees the record entirely and caller
may retry copying data from user space buffer again.
Third patch fixes a bug in the TLS 1.3 code spotted while working
on patch 2. TLS 1.3 may effectively overflow the SG list which
leads to the BUG() in sg_page() being triggered.
Patch 4 adds a test case which triggers this bug reliably.
Next two patches are small cleanups of dead code and code which
makes dangerous assumptions.
Last but not least two minor improvements to the sockmap tests.
Tested:
- bpf/test_sockmap
- net/tls
- syzbot repro (which used error injection, hence no direct
selftest is added to preserve it).

Partially sent record cleanup path increments an SG entry
directly instead of using sg_next(). This should not be a
problem today, as encrypted messages should be always
allocated as arrays. But given this is a cleanup path it's
easy to miss was this ever to change. Use sg_next(), and
simplify the code.

Looks like when BPF support was added by commit d3b18ad31f93
("tls: add bpf support to sk_msg handling") and
commit d829e9c4112b ("tls: convert to generic sk_msg interface")
it broke/removed the support for in-place crypto as added by
commit 4e6d47206c32 ("tls: Add support for inplace records
encryption").
The inplace_crypto member of struct tls_rec is dead, inited
to zero, and sometimes set to zero again. It used to be
set to 1 when record was allocated, but the skmsg code doesn't
seem to have been written with the idea of in-place crypto
in mind.
Since non trivial effort is required to bring the feature back
and we don't really have the HW to measure the benefit just
remove the left over support for now to avoid confusing readers.

TLS 1.3 started using the entry at the end of the SG array
for chaining-in the single byte content type entry. This mostly
works:
[ E E E E E E . . ]
^ ^
start end
E < content type
/
[ E E E E E E C . ]
^ ^
start end
(Where E denotes a populated SG entry; C denotes a chaining entry.)
If the array is full, however, the end will point to the start:
[ E E E E E E E E ]
^
start
end
And we end up overwriting the start:
E < content type
/
[ C E E E E E E E ]
^
start
end
The sg array is supposed to be a circular buffer with start and
end markers pointing anywhere. In case where start > end
(i.e. the circular buffer has "wrapped") there is an extra entry
reserved at the end to chain the two halves together.
[ E E E E E E . . l ]
(Where l is the reserved entry for "looping" back to front.
As suggested by John, let's reserve another entry for chaining
SG entries after the main circular buffer. Note that this entry
has to be pointed to by the end entry so its position is not fixed.
Examples of full messages:
[ E E E E E E E E . l ]
^ ^
start end
<---------------.
[ E E . E E E E E E l ]
^ ^
end start
Now the end will always point to an unused entry, so TLS 1.3
can always use it.

When tls_do_encryption() fails the SG lists are left with the
SG_END and SG_CHAIN marks in place. One could hope that once
encryption fails we will never see the record again, but that
is in fact not true. Commit d3b18ad31f93 ("tls: add bpf support
to sk_msg handling") added special handling to ENOMEM and ENOSPC
errors which mean we may see the same record re-submitted.
As suggested by John free the record, the BPF code is already
doing just that.

We've added the bass speaker support on Acer 8951G by the commit
00066e9733f6 ("Add Acer Aspire Ethos 8951G model quirk"), but it seems
that the GPIO pin was wrongly set: while the commit turns off the bit
to power up the amp, the actual hardware reacts other way round,
i.e. GPIO bit on = amp on.
So this patch fixes the bug, turning on the GPIO bit 0x02 as default.
Since turning on the GPIO bit can be more easily managed with
alc_setup_gpio() call, we simplify the quirk code by integrating the
GPIO setup into the existing alc662_fixup_aspire_ethos_hp() and
dropping the whole ALC669_FIXUP_ACER_ASPIRE_ETHOS_SUBWOOFER quirk.

This reverts commit 193d00a2b35ee3353813b4006a18131122087205.
Commit 951d48855d86 ("of: Make of_dma_get_range() work on bus nodes")
reworked the logic such that of_dma_get_range() works correctly
starting from a bus node containing "dma-ranges".
Since on Juno we don't have a SoC level bus node and "dma-ranges" is
present only in the root node, we get the following error:
OF: translation of DMA address(0) to CPU address failed node(/sram@2e000000)
OF: translation of DMA address(0) to CPU address failed node(/uart@7ff80000)
...
OF: translation of DMA address(0) to CPU address failed node(/mhu@2b1f0000)
OF: translation of DMA address(0) to CPU address failed node(/iommu@2b600000)
OF: translation of DMA address(0) to CPU address failed node(/iommu@2b600000)
OF: translation of DMA address(0) to CPU address failed node(/iommu@2b600000)
So let's fix it by dropping the "dma-ranges" property for now. This
should be fine since it doesn't represent any kind of device-visible
restriction; it was only there for completeness, and we've since given
in to the assumption that missing "dma-ranges" implies a 1:1 mapping
anyway.
We can add it later with a proper SoC bus node and moving all the
devices that belong there along with the "dma-ranges" if required.

There are only few users, so this patch converts the I2C core and all

so out-of-tree users will get a build failure to understand they need to
