Add reset deassertion for Aspeed MDIO
Add missing reset deassertion for Aspeed MDIO bus controller. The reset
is asserted by the hardware when power-on so the driver only needs to
deassert it. To be able to work with the old DT blobs, the reset is
optional since it may be deasserted by the bootloader or the previous
kernel.
V6:
- fix merge conflict for net-next
V5:
- fix error of dt_binding_check
V4:
- use ASPEED_RESET_MII instead of hardcoding in dt-binding example
V3:
- remove reset property from the required list of the device tree
bindings
- remove "Cc: stable@vger.kernel.org" from the commit messages
- add more description in the commit message of the dt-binding
V2:
- add reset property in the device tree bindings
- add reset assertion in the error path and driver remove

The AST2600 MDIO bus controller has a reset control bit and must be
deasserted before manipulating the MDIO controller. By default, the
hardware asserts the reset so the driver only need to deassert it.
Regarding to the old DT blobs which don't have reset property in them,
the reset deassertion is usually done by the bootloader so the reset
property is optional to work with them.

Calling tls_append_frag when max_open_record_len == record->len might
add an empty fragment to the TLS record if the call happens to be on the
page boundary. Normally tls_append_frag coalesces the zero-sized
fragment to the previous one, but not if it's on page boundary.
If a resync happens then, the mlx5 driver posts dump WQEs in
tx_post_resync_dump, and the empty fragment may become a data segment
with byte_count == 0, which will confuse the NIC and lead to a CQE
error.
This commit fixes the described issue by skipping tls_append_frag on
zero size to avoid adding empty fragments. The fix is not in the driver,
because an empty fragment is hardly the desired behavior.

kasan: prevent cpu_quarantine corruption when CPU offline and cache shrink occur at same time
kasan_quarantine_remove_cache() is called in kmem_cache_shrink()/
destroy(). The kasan_quarantine_remove_cache() call is protected by
cpuslock in kmem_cache_destroy() to ensure serialization with
kasan_cpu_offline().
However the kasan_quarantine_remove_cache() call is not protected by
cpuslock in kmem_cache_shrink(). When a CPU is going offline and cache
shrink occurs at same time, the cpu_quarantine may be corrupted by
interrupt (per_cpu_remove_cache operation).
So add a cpu_quarantine offline flags check in per_cpu_remove_cache().

The Sapphire Rapids (SPR) C6 optimization was added to the end of the
'spr_idle_state_table_update()' function. However, the function has a
'return' which may happen before the optimization has a chance to run.
And this may prevent the optimization from happening.
This is an unlikely scenario, but possible if user boots with, say,
the 'intel_idle.preferred_cstates=6' kernel boot option.
This patch fixes the issue by eliminating the problematic 'return'
statement.

Problem description.
When user boots kernel up with the 'intel_idle.preferred_cstates=4' option,
we enable C1E and disable C1 states on Sapphire Rapids Xeon (SPR). In order
for C1E to work on SPR, we have to enable the C1E promotion bit on all
CPUs. However, we enable it only on one CPU.
Fix description.
The 'intel_idle' driver already has the infrastructure for disabling C1E
promotion on every CPU. This patch uses the same infrastructure for
enabling C1E promotion on every CPU. It changes the boolean
'disable_promotion_to_c1e' variable to a tri-state 'c1e_promotion'
variable.
Tested on a 2-socket SPR system. I verified the following combinations:
* C1E promotion enabled and disabled in BIOS.
* Booted with and without the 'intel_idle.preferred_cstates=4' kernel
argument.
In all 4 cases C1E promotion was correctly set on all CPUs.
Also tested on an old Broadwell system, just to make sure it does not cause
a regression. C1E promotion was correctly disabled on that system, both C1
and C1E were exposed (as expected).

Note that hex_to_bin returns -1 on error and hex2bin return -EINVAL on

The function hex2bin is used to load cryptographic keys into device
mapper targets dm-crypt and dm-integrity. It should take constant time
independent on the processed data, so that concurrently running
unprivileged code can't infer any information about the keys via
microarchitectural convert channels.
This patch changes the function hex_to_bin so that it contains no
branches and no memory accesses.
Note that this shouldn't cause performance degradation because the size
of the new function is the same as the size of the old function (on
x86-64) - and the new function causes no branch misprediction penalties.

Before this commit fan_curve_check_present() was trying to not cause
the probe to fail on devices without fan curve control by testing for
known error codes returned by asus_wmi_evaluate_method_buf().
Checking for ENODATA or ENODEV, with the latter being returned by this
function when an ACPI integer with a value of ASUS_WMI_UNSUPPORTED_METHOD
is returned. But for other ACPI integer returns this function just returns
them as is, including the ASUS_WMI_DSTS_UNKNOWN_BIT value of 2.
On the Asus U36SD ASUS_WMI_DSTS_UNKNOWN_BIT gets returned, leading to:
asus-nb-wmi: probe of asus-nb-wmi failed with error 2

R > I Flags [S.], seq 2699962254, ack 3451342530, win 65535, options [..]
R > I Flags [P.], seq 1:89, ack 1, [..]
Note 3rd ACK is from responder to initiator so following branch is taken:
} else if (((state->state == TCP_CONNTRACK_SYN_SENT
&& dir == IP_CT_DIR_ORIGINAL)
|| (state->state == TCP_CONNTRACK_SYN_RECV
&& dir == IP_CT_DIR_REPLY))
&& after(end, sender->td_end)) {
... because state == TCP_CONNTRACK_SYN_RECV and dir is REPLY.
This causes the scaling factor to be reset to 0: window scale option
is only present in syn(ack) packets. This in turn makes nf_conntrack
mark valid packets as out-of-window.
This was always broken, it exists even in original commit where
window tracking was added to ip_conntrack (nf_conntrack predecessor)
in 2.6.9-rc1 kernel.
Restrict to 'tcph->syn', just like the 3rd condtional added in
commit 82b72cb946 ("netfilter: conntrack: re-init state for retransmitted syn-ack").
Upon closer look, those conditionals/branches can be merged:
Because earlier checks prevent syn-ack from showing up in
original direction, the 'dir' checks in the conditional quoted above are
redundant, remove them. Return early for pure syn retransmitted in reply

mptcp: Timeout for MP_FAIL response
When one peer sends an infinite mapping to coordinate fallback from
MPTCP to regular TCP, the other peer is expected to send a packet with
the MPTCP MP_FAIL option to acknowledge the infinite mapping. Rather
than leave the connection in some half-fallback state, this series adds
a timeout after which the infinite mapping sender will reset the
connection.
Patch 1 adds a fallback self test.
Patches 2-5 make use of the MPTCP socket's retransmit timer to reset the
MPTCP connection if no MP_FAIL was received.
Patches 6 and 7 extends the self test to check MP_FAIL-related MIBs.

This patch extends chk_fail_nr to check the MP_FAIL response mibs.
Add a new argument invert for chk_fail_nr to allow it can check the
MP_FAIL TX and RX mibs from the opposite direction.
When the infinite map is received before the MP_FAIL response, the
response will be lost. A '-' can be added into fail_tx or fail_rx to
represent that MP_FAIL response TX or RX can be lost when doing the
checks.
