"This fixes one minor regression from the btree cache fixes (in the
scan_for_btree_nodes repair path) - and the shutdown path fix is the
big one here, in terms of bugs closed:
- Assorted tiny syzbot fixes
- Shutdown path fix: "bch2_btree_write_buffer_flush_going_ro()"
The shutdown path wasn't flushing the btree write buffer, leading
to shutting down while we still had operations in flight. This

Add support for the 'ethtool -d <dev>' command to retrieve and print
a register dump for fbnic. The dump defaults to version 1 and consists
of two parts: all the register sections that can be dumped linearly, and
an RPC RAM section that is structured in an interleaved fashion and
requires special handling. For each register section, the dump also
contains the start and end boundary information which can simplify parsing.

v2: only add/del mcast group on backup slaves when arp_validate is set (Jay Vosburgh)
arp_validate doesn't support 3ad, tlb, alb. So let's only do it on ab mode.

Commit 4598380f9c ("bonding: fix ns validation on backup slaves")
tried to resolve the issue where backup slaves couldn't be brought up when
receiving IPv6 Neighbor Solicitation (NS) messages. However, this fix only
worked for drivers that receive all multicast messages, such as the veth
interface.
For standard drivers, the NS multicast message is silently dropped because
the slave device is not a member of the NS target multicast group.
To address this, we need to make the slave device join the NS target
multicast group, ensuring it can receive these IPv6 NS messages to validate
the slave’s status properly.
There are three policies before joining the multicast group:
1. All settings must be under active-backup mode (alb and tlb do not support
arp_validate), with backup slaves and slaves supporting multicast.
2. We can add or remove multicast groups when arp_validate changes.
3. Other operations, such as enslaving, releasing, or setting NS targets,
need to be guarded by arp_validate.

The first PPS latch time needs to be calculated by the driver
(in rounded off seconds) and configured as the start time
offset for the cycle. After synchronizing two PTP clocks
running as master/slave, missing this would cause master
and slave to start immediately with some milliseconds
drift which causes the PPS signal to never synchronize with
the PTP master.

This is not a problem per see, since the RTNL lock is held here, so, it
is safe to iterate in the list without the RCU read lock, as suggested
by Eric.
To alleviate the concern, modify the code to use
list_for_each_entry_rcu() with the RTNL-held argument.
The annotation will raise an error only if RTNL or RCU read lock are
missing during iteration, signaling a legitimate problem, otherwise it
will avoid this false positive.
This will solve the IPv6 case as well, since ip6mr_rtm_dumproute() calls
this function as well.

a result of commit 3e43b903da ("net: phy: Immediately call

it is now possible that phy_link_down() and phy_link_up() will both
complete before phylink's resolver has run, which means it'll miss that
pl->phy_state.link momentarily became false.
Rename "mac_link_dropped" to be more generic "link_failed" since it will
cover more than the MAC/PCS end of the link failing, and arrange to set
this in phylink_phy_change() if we notice that the PHY reports that the
link is down.

The PTP_TCR (Timestamp Control Register) is used to configure several
features related to packet timestamping.
On one hand, it configures the 1588 packet processing, to indicate what
types of frames should be timestamped (all, only 1588v1 or 1588v2, using
L2 or L4 timestamping, on IPv4 or IPv6, etc.). This is congfigured
usually through the ioctl / ndo dedicated for such setup. This
configuration is done by setting some fields in that register, that seem
to behave the same way on all dwmac variants, including DWMAC1000.
On the other hand, and only on DWMAC1000 apparently, some fields in that
register are used to configure external snapshots (bits 24/25).
On DWMAC4 and others, these fields are reserved and external
snapshots are configured through a dedicated register that simply
doesn't seem to exist on DWMAC1000.
This configuration is done in the dwmac1000-specific ptp_clock_info ops
(cf dwmac1000_ptp_enable()).
So to avoid the timestamping configuration interfering with the external
snapshots, this commit makes sure that the config_hw_tstamping only
configures the relevant bits in PTP_TCR, so that the DWMAC1000
timestamping can correctly rely on these otherwise reserved fields.

The default configuration for the interrupts on dwmac1000 have the
timestamping interrupt masked. Now that the timestamping has been
adapted to dwmac1000, enable the timestamping interrupt on these
platforms.
On dwmac1000, the external snapshot interrupt is configured through a
dedicated bit, that is set as reserved on other dwmac variants. The
timestaming interrupt is acknowledged by reading the
GMAC3_X_TIMESTAMP_STATUS register.
Make sure that this interrupt is enabled when snapshot is enabled, and
masked when disabled.

The PTP configuration for GMAC3_X differs from the other implementations
in several ways :
- There's only one external snapshot trigger
- The snapshot configuration is done through the PTP_TCR register,
whereas the other dwmac variants have a dedicated ACR (auxiliary
control reg) for that purpose
- The layout for the PTP_TCR register also differs, as bits 24/25 are
used for the snapshot configuration. These bits are reserved on other
variants.
On GMAC3_X, we also can't discover the number of snapshot triggers
automatically.
The GMAC3_X has one PPS output, however it's configuration isn't
supported yet so report 0 n_per_out for now.
Introduce a dedicated set of ptp_clock_info ops and configuration
parameters to reflect these differences specific to GMAC3_X.
This was tested on dwmac_socfpga.

In mptcp_pm_create_subflow_or_signal_addr(), rcu_read_(un)lock() are
used as expected to iterate over the list of local addresses, but
list_for_each_entry() was used instead of list_for_each_entry_rcu() in
__lookup_addr(). It is important to use this variant which adds the
required READ_ONCE() (and diagnostic checks if enabled).
Because __lookup_addr() is also used in mptcp_pm_nl_set_flags() where it
is called under the pernet->lock and not rcu_read_lock(), an extra
condition is then passed to help the diagnostic checks making sure
either the associated spin lock or the RCU lock is held.
