If we ever get to a point again where we convert a bogus looking <ptr>_or_null
typed register containing a non-zero fixed or variable offset, then lets not
reset these bounds to zero since they are not and also don't promote the register
to a <ptr> type, but instead leave it as <ptr>_or_null. Converting to a unknown
register could be an avenue as well, but then if we run into this case it would
allow to leak a kernel pointer this way.

sock_map_link() is called to update a sockmap entry with a sk. But, if the
sock_map_init_proto() call fails then we return an error to the map_update
op against the sockmap. In the error path though we need to cleanup psock
and dec the refcnt on any programs associated with the map, because we
refcnt them early in the update process to ensure they are pinned for the
psock. (This avoids a race where user deletes programs while also updating
the map with new socks.)
In current code we do the prog refcnt dec explicitely by calling
bpf_prog_put() when the program was found in the map. But, after commit
'38207a5e81230' in this error path we've already done the prog to psock
assignment so the programs have a reference from the psock as well. This
then causes the psock tear down logic, invoked by sk_psock_put() in the
error path, to similarly call bpf_prog_put on the programs there.
To be explicit this logic does the prog->psock assignment:
if (msg_*)
psock_set_prog(...)
Then the error path under the out_progs label does a similar check and
dec with:
if (msg_*)
bpf_prog_put(...)
And the teardown logic sk_psock_put() does ...
psock_set_prog(msg_*, NULL)
... triggering another bpf_prog_put(...). Then KASAN gives us this splat,
found by syzbot because we've created an inbalance between bpf_prog_inc and
bpf_prog_put calling put twice on the program.

To fix clean up error path so it doesn't try to do the bpf_prog_put in the
error path once progs are assigned then it relies on the normal psock
tear down logic to do complete cleanup.
For completness we also cover the case whereh sk_psock_init_strp() fails,
but this is not expected because it indicates an incorrect socket type
and should be caught earlier.

Applications can be confused slightly because we do not always return the
same error code as expected, e.g. what the TCP stack normally returns. For
example on a sock err sk->sk_err instead of returning the sock_error we
return EAGAIN. This usually means the application will 'try again'
instead of aborting immediately. Another example, when a shutdown event
is received we should immediately abort instead of waiting for data when
the user provides a timeout.
These tend to not be fatal, applications usually recover, but introduces
bogus errors to the user or introduces unexpected latency. Before
'c5d2177a72a16' we fell back to the TCP stack when no data was available
so we managed to catch many of the cases here, although with the extra
latency cost of calling tcp_msg_wait_data() first.
To fix lets duplicate the error handling in TCP stack into tcp_bpf so
that we get the same error codes.
These were found in our CI tests that run applications against sockmap
and do longer lived testing, at least compared to test_sockmap that
does short-lived ping/pong tests, and in some of our test clusters
we deploy.
Its non-trivial to do these in a shorter form CI tests that would be
appropriate for BPF selftests, but we are looking into it so we can
ensure this keeps working going forward. As a preview one idea is to
pull in the packetdrill testing which catches some of this.

The following error is reported when running "./test_progs -t for_each"
under arm64:
bpf_jit: multi-func JIT bug 58 != 56
[...]
JIT doesn't support bpf-to-bpf calls
The root cause is the size of BPF_PSEUDO_FUNC instruction increases
from 2 to 3 after the address of called bpf-function is settled and
there are two bpf-to-bpf calls in test_pkt_access. The generated
instructions are shown below:
0x48: 21 00 C0 D2 movz x1, #0x1, lsl #32
0x4c: 21 00 80 F2 movk x1, #0x1

0x50: 81 70 9F F2 movk x1, #0xfb84
Fixing it by using emit_addr_mov_i64() for BPF_PSEUDO_FUNC, so
the size of jited image will not change.

If command prep fails, current handling will orphan subsequent requests
in the list. Consider a simple example:
rqlist = [ 1 -> 2 ]
When prep for request '1' fails, it will be appended to the
'requeue_list', leaving request '2' disconnected from the original
rqlist and no longer tracked. Meanwhile, rqlist is still pointing to the
failed request '1' and will attempt to submit the unprepped command.
Fix this by updating the rqlist accordingly using the request list
helper functions.

The four RGMII interface modes take care of the required RGMII delay
configuration at the PHY and should not be limited by the network MAC
driver. Sadly, gemini was only permitting RGMII mode with no delays,
which would require the required delay to be inserted via PCB tracking
or by the MAC.
However, there are designs that require the PHY to add the delay, which
is impossible without Gemini permitting the other three PHY interface
modes. Fix the driver to allow these.

Russell King says:
====================
Fix RGMII delays for 88E1118
This series fixes the RGMII delays for 88E1118 Marvell PHYs, after
a report by Corentin Labbe that the Marvell driver fails to work.
Patch 1 cleans up the paged register accesses in m88e1118_config_init()
and patch 2 adds the RGMII delay configuration.
This comes with an element of risk as existing DT may need to be fixed
for this in a similar way as we have done in the recent past for other
PHY drivers that have misinterpreted the RGMII interface modes.

Corentin Labbe reports that the SSI 1328 does not work when allowing
the PHY to operate at gigabit speeds, but does work with the generic
PHY driver.
This appears to be because m88e1118_config_init() writes a fixed value
to the MSCR register, claiming that this is to enable 1G speeds.
However, this always sets bits 4 and 5, enabling RGMII transmit and
receive delays. The suspicion is that the original board this was
added for required the delays to make 1G speeds work.
Add the necessary configuration for RGMII delays for the 88E1118 to
bring this into line with the requirements for RGMII support, and thus
make the SSI 1328 work.
Corentin Labbe has tested this on gemini-ssi1328 and gemini-ns2502.

The format of the arm64 and x86 exception table entries is essentially
the same as of commits:
46d28947d9876fc0 ("x86/extable: Rework the exception table mechanics")
d6e2cc5647753825 ("arm64: extable: add `type` and `data` fields")
Both use a 12-byte entry consisting of two 32-bit relative offsets and
32 bits of (absolute) data, and their sort functions are identical aside
from commentary, with arm64 saying:
/* Don't touch the fixup type or data */
... and x86 saying:
/* Don't touch the fixup type */
Unify the two behind a common sort_relative_table_with_data() function,
retaining the arm64 commentary.
There should be no functional change as a result of this patch.

There are currently 2 ways to create a set of sysfs files for a
kobj_type, through the default_attrs field, and the default_groups
field. Move the cpuidle sysfs code to use default_groups field which
has been the preferred way since aa30f47cf666 ("kobject: Add support for
default attribute groups to kobj_type") so that we can soon get rid of
the obsolete default_attrs field.

====================
pull-request: ieee802154 for net 2022-01-05
Below I have a last minute fix for the atusb driver.
Pavel fixes a KASAN uninit report for the driver. This version is the
minimal impact fix to ease backporting. A bigger rework of the driver to
avoid potential similar problems is ongoing and will come through net-next
when ready.

The speaker fixup that is used for the Yoga 7 14ITL5 also applies to
the IdeaPad Slim 9i 14ITL5. The attached patch applies the quirk to
initialise the amplifier on the IdeaPad Slim 9i as well.
This is validated to work on my laptop.

A randconfig caught a compile warning that is now treated as a fatal
error:
sound/soc/codecs/ak4375.c:415:13: error: ‘ak4375_power_off’ defined but not used [-Werror=unused-function]
where ak4375_power_off() is used only from the PM handler.
As both suspend and resumes are already marked with __maybe_unused,
let's rip off the superfluous ifdef CONFIG_PM, so that the error above
can be avoided.

The issue takes place in one error path of clusterip_tg_check(). When
memcmp() returns nonzero, the function simply returns the error code,
forgetting to decrease the reference count of a clusterip_config
object, which is bumped earlier by clusterip_config_find_get(). This
may incur reference count leak.
Fix this issue by decrementing the refcount of the object in specific
error path.
