occur when the system is suspended and the anchored kill function
is called. To avoid this, add protection to prevent executing the

The PHY built in to the Realtek RTL8366S switch controller was
previously supported by genphy_driver. This PHY does not implement MMD
operations. Since commit 9b01c885be36 ("net: phy: c22: migrate to
genphy_c45_write_eee_adv()"), MMD register reads have been made during
phy_probe to determine EEE support. For genphy_driver, these reads are
transformed into 802.3 annex 22D clause 45-over-clause 22
mmd_phy_indirect operations that perform MII register writes to
MII_MMD_CTRL and MII_MMD_DATA. This overwrites those two MII registers,
which on this PHY are reserved and have another function, rendering the
PHY unusable while so configured.
Proper support for this PHY is restored by providing a phy_driver that
declares MMD operations as unsupported by using the helper functions
provided for that purpose, while remaining otherwise identical to
genphy_driver.

The REQUEST_PROC_DAA command behaves differently from other commands.
Sometimes the hardware can auto emit STOP, but in other conditions, it
cannot.
Improves the code logic to better handle these situations.
Hardware can auto emit STOP only when the following conditions are met:
- The previous I3C device correctly returns a PID and ACKs an I3C address.
- A NACK is received when emitting 7E to try to get the next I3C device's
PID.
In all other cases, a manual STOP emission is needed.
The code is changed to emit STOP when break the while loop and 'return 0'
only when the hardware can auto emit STOP.

I was wrong about the TABLE_SIZE field description in the
commit 0676bfebf576 ("i3c: mipi-i3c-hci: Fix DAT/DCT entry sizes").
For the MIPI I3C HCI versions 1.0 and earlier the TABLE_SIZE field in
the registers DAT_SECTION_OFFSET and DCT_SECTION_OFFSET is indeed defined
in DWORDs and not number of entries like it is defined in later versions.
Where above fix allowed driver initialization to continue the wrongly
interpreted TABLE_SIZE field leads variables DAT_entries being twice and
DCT_entries four times as big as they really are.
That in turn leads clearing the DAT table over the boundary in the
dat_v1.c: hci_dat_v1_init().
So interprete the TABLE_SIZE field in DWORDs for HCI versions < 1.1 and
fix number of DAT/DCT entries accordingly.

According to I3C Spec 1.1.1, 11-Jun-2021, section: 5.1.2.2.3:
If the Controller chooses to start an I3C Message with an I3C Dynamic
Address, then special provisions shall be made because that same I3C Target
may be initiating an IBI or a Controller Role Request. So, one of three
things may happen: (skip 1, 2)
3. The Addresses match and the RnW bits also match, and so neither
Controller nor Target will ACK since both are expecting the other side to
provide ACK. As a result, each side might think it had "won" arbitration,
but neither side would continue, as each would subsequently see that the
other did not provide ACK.
...
For either value of RnW: Due to the NACK, the Controller shall defer the
Private Write or Private Read, and should typically transmit the Target
^^^^^^^^^^^^^^^^^^^
Address again after a Repeated START (i.e., the next one or any one prior
^^^^^^^^^^^^^
to a STOP in the Frame). Since the Address Header following a Repeated
START is not arbitrated, the Controller will always win (see Section
5.1.2.2.4).
Resend target address again if address is not 7E and controller get NACK.

The ext interrupts are enabled when the firmware has been started, but
this may never happen, for example, if the board configuration file is
missing.
When the system is later suspended, the driver unconditionally tries to
disable interrupts, which results in an irq disable imbalance and causes
the driver to spin indefinitely in napi_synchronize().
Make sure that the interrupts have been enabled before attempting to
disable them.

It could lead to error happen because the variable res is not updated if
the call to sr_share_read_word returns an error. In this particular case
error code was returned and res stayed uninitialized. Same issue also
applies to sr_read_reg.
This can be avoided by checking the return value of sr_share_read_word
and sr_read_reg, and propagating the error if the read operation failed.
Found by code review.

In __bnxt_reserve_rings(), the existing code unconditionally sets the
default RSS indirection table to default if netif_is_rxfh_configured()
returns false. This used to be correct before we added RSS contexts
support. For example, if the user is changing the number of ethtool
channels, we will enter this path to reserve the new number of rings.
We will then set the RSS indirection table to default to cover the new
number of rings if netif_is_rxfh_configured() is false.
Now, with RSS contexts support, if the user has added or deleted RSS
contexts, we may now enter this path to reserve the new number of VNICs.
However, netif_is_rxfh_configured() will not return the correct state if
we are still in the middle of set_rxfh(). So the existing code may
set the indirection table of the default RSS context to default by
mistake.
Fix it to check if the reservation of the RX rings is changing. Only
check netif_is_rxfh_configured() if it is changing. RX rings will not
change in the middle of set_rxfh() and this will fix the issue.

Pull driver core updates from Greg KH:
"Here is the big set of driver core changes for 6.11-rc1.
Lots of stuff in here, with not a huge diffstat, but apis are evolving
which required lots of files to be touched. Highlights of the changes
in here are:
- platform remove callback api final fixups (Uwe took many releases
to get here, finally!)
- Rust bindings for basic firmware apis and initial driver-core
interactions.
It's not all that useful for a "write a whole driver in rust" type
of thing, but the firmware bindings do help out the phy rust
drivers, and the driver core bindings give a solid base on which
others can start their work.
There is still a long way to go here before we have a multitude of
rust drivers being added, but it's a great first step.
- driver core const api changes.
This reached across all bus types, and there are some fix-ups for
some not-common bus types that linux-next and 0-day testing shook
out.
This work is being done to help make the rust bindings more safe,
as well as the C code, moving toward the end-goal of allowing us to
put driver structures into read-only memory. We aren't there yet,
but are getting closer.
- minor devres cleanups and fixes found by code inspection
- arch_topology minor changes

The cited commit missed to check against the validity of the frame length
in the tun_xdp_one() path, which could cause a corrupted skb to be sent
downstack. Even before the skb is transmitted, the
tun_xdp_one-->eth_type_trans() may access the Ethernet header although it
can be less than ETH_HLEN. Once transmitted, this could either cause
out-of-bound access beyond the actual length, or confuse the underlayer
with incorrect or inconsistent header length in the skb metadata.
In the alternative path, tun_get_user() already prohibits short frame which
has the length less than Ethernet header size from being transmitted for
IFF_TAP.
This is to drop any frame shorter than the Ethernet header size just like
how tun_get_user() does.

The NIC requires each TSO segment to not span more than 10
descriptors. NIC further requires each descriptor to not exceed
16KB - 1 (GVE_TX_MAX_BUF_SIZE_DQO).
The descriptors for an skb are generated by
gve_tx_add_skb_no_copy_dqo() for DQO RDA queue format.
gve_tx_add_skb_no_copy_dqo() loops through each skb frag and
generates a descriptor for the entire frag if the frag size is
not greater than GVE_TX_MAX_BUF_SIZE_DQO. If the frag size is
greater than GVE_TX_MAX_BUF_SIZE_DQO, it is split into descriptor(s)
of size GVE_TX_MAX_BUF_SIZE_DQO and a descriptor is generated for
the remainder (frag size % GVE_TX_MAX_BUF_SIZE_DQO).
gve_can_send_tso() checks if the descriptors thus generated for an
skb would meet the requirement that each TSO-segment not span more
than 10 descriptors. However, the current code misses an edge case
when a TSO segment spans multiple descriptors within a large frag.
This change fixes the edge case.
gve_can_send_tso() relies on the assumption that max gso size (9728)
is less than GVE_TX_MAX_BUF_SIZE_DQO and therefore within an skb
fragment a TSO segment can never span more than 2 descriptors.

When the netdev_rx_queue_restart() restarts queues, the bnxt_en driver
updates(creates and deletes) a page_pool.
But it doesn't update xdp_rxq_info, so the xdp_rxq_info is still
connected to an old page_pool.
So, bnxt_rx_ring_info->page_pool indicates a new page_pool, but
bnxt_rx_ring_info->xdp_rxq is still connected to an old page_pool.
An old page_pool is no longer used so it is supposed to be
deleted by page_pool_destroy() but it isn't.
Because the xdp_rxq_info is holding the reference count for it and the
xdp_rxq_info is not updated, an old page_pool will not be deleted in
the queue restart logic.
Before restarting 1 queue:
./tools/net/ynl/samples/page-pool
enp10s0f1np1[6] page pools: 4 (zombies: 0)
refs: 8192 bytes: 33554432 (refs: 0 bytes: 0)
recycling: 0.0% (alloc: 128:8048 recycle: 0:0)
After restarting 1 queue:
./tools/net/ynl/samples/page-pool
enp10s0f1np1[6] page pools: 5 (zombies: 0)
refs: 10240 bytes: 41943040 (refs: 0 bytes: 0)
recycling: 20.0% (alloc: 160:10080 recycle: 1920:128)
Before restarting queues, an interface has 4 page_pools.
After restarting one queue, an interface has 5 page_pools, but it
should be 4, not 5.
The reason is that queue restarting logic creates a new page_pool and
an old page_pool is not deleted due to the absence of an update of
xdp_rxq_info logic.

The of_property_for_each_u32() macro needs five parameters, two of which
are primarily meant as internal variables for the macro itself (in the
for() clause). Yet these two parameters are used by a few drivers, and this
can be considered misuse or at least bad practice.
Now that the kernel uses C11 to build, these two parameters can be avoided
by declaring them internally, thus changing this pattern:
struct property *prop;
const __be32 *p;
u32 val;
of_property_for_each_u32(np, "xyz", prop, p, val) { ... }
to this:
u32 val;
of_property_for_each_u32(np, "xyz", val) { ... }
However two variables cannot be declared in the for clause even with C11,
so declare one struct that contain the two variables we actually need. As
the variables inside this struct are not meant to be used by users of this
macro, give the struct instance the noticeable name "_it" so it is visible
during code reviews, helping to avoid new code to use it directly.
Most usages are trivially converted as they do not use those two
parameters, as expected. The non-trivial cases are:
- drivers/clk/clk.c, of_clk_get_parent_name(): easily doable anyway
- drivers/clk/clk-si5351.c, si5351_dt_parse(): this is more complex as the
checks had to be replicated in a different way, making code more verbose
and somewhat uglier, but I refrained from a full rework to keep as much
of the original code untouched having no hardware to test my changes
All the changes have been build tested. The few for which I have the
hardware have been runtime-tested too.

Expanding on the previous commit, assuming that rbd_is_lock_owner()
always returns true (i.e. that we are either in RBD_LOCK_STATE_LOCKED
or RBD_LOCK_STATE_QUIESCING) if the mapping is exclusive is wrong too.
In case ceph_cls_set_cookie() fails, the lock would be temporarily
released even if the mapping is exclusive, meaning that we can end up
even in RBD_LOCK_STATE_UNLOCKED.
IOW, exclusive mappings are really "just" about disabling automatic
lock transitions (as documented in the man page), not about grabbing
the lock and holding on to it whatever it takes.
