Windows SR-IOV provides a backchannel mechanism in software for communication
between a VF driver and a PF driver. These "configuration blocks" are
similar in concept to PCI configuration space, but instead of doing reads and
writes in 32-bit chunks through a very slow path, packets of up to 128 bytes
can be sent or received asynchronously.
Nearly every SR-IOV device contains just such a communications channel in
hardware, so using this one in software is usually optional. Using the
software channel, however, allows driver implementers to leverage software
tools that fuzz the communications channel looking for vulnerabilities.
The usage model for these packets puts the responsibility for reading or
writing on the VF driver. The VF driver sends a read or a write packet,
indicating which "block" is being referred to by number.
If the PF driver wishes to initiate communication, it can "invalidate" one or
more of the first 64 blocks. This invalidation is delivered via a callback
supplied by the VF driver by this driver.
No protocol is implied, except that supplied by the PF and VF drivers.

If a CCP is unconfigured (e.g. there are no available queues) then
there will be no data structures allocated for the device. Thus, we
must check for validity of a pointer before trying to access structure

In commit 93a714d6b53d ("multicast: Extend ip address command to enable
multicast group join/leave on") we added a new flag IFA_F_MCAUTOJOIN
to make user able to add multicast address on ethernet interface.
This works for IPv4, but not for IPv6. See the inet6_addr_add code.
static int inet6_addr_add()
{
...
if (cfg->ifa_flags & IFA_F_MCAUTOJOIN) {
ipv6_mc_config(net->ipv6.mc_autojoin_sk, true...)
}
ifp = ipv6_add_addr(idev, cfg, true, extack); <- always fail with maddr
if (!IS_ERR(ifp)) {
...
} else if (cfg->ifa_flags & IFA_F_MCAUTOJOIN) {
ipv6_mc_config(net->ipv6.mc_autojoin_sk, false...)
}
}
But in ipv6_add_addr() it will check the address type and reject multicast
address directly. So this feature is never worked for IPv6.
We should not remove the multicast address check totally in ipv6_add_addr(),
but could accept multicast address only when IFA_F_MCAUTOJOIN flag supplied.

The SF2 binding does not specify that the CPU port should have
properties mandatory for successfully instantiating a PHYLINK object. As
such, there will be missing properties (including fixed-link) and when
attempting to validate and later configure link modes, we will have an
incorrect set of parameters (interface, speed, duplex).
Simply prevent the CPU port from being configured through PHYLINK since
bcm_sf2_imp_setup() takes care of that already.

====================
mlx5 tc flow handling for concurrent execution (Part 3)
This series includes updates to mlx5 ethernet and core driver:
Vlad submits part 3 of 3 part series to allow TC flow handling
for concurrent execution.
Vlad says:
==========
Structure mlx5e_neigh_hash_entry code that uses it are refactored in
following ways:
- Extend neigh_hash_entry with rcu and modify its users to always take
reference to the structure when using it (neigh_hash_entry has already
had atomic reference counter which was only used when scheduling neigh
update on workqueue from atomic context of neigh update netevent).
- Always use mlx5e_neigh_update_table->encap_lock when modifying neigh
update hash table and list. Originally, this lock was only used to
synchronize with netevent handler function, which is called from bh
context and cannot use rtnl lock for synchronization. Use rcu read lock
instead of encap_lock to lookup nhe in atomic context of netevent even
handler function. Convert encap_lock to mutex to allow creating new
neigh hash entries while holding it, which is safe to do because the
lock is no longer used in atomic context.
- Rcu-ify mlx5e_neigh_hash_entry->encap_list by changing operations on
encap list to their rcu counterparts and extending encap structure
with rcu_head to free the encap instances after rcu grace period. This
allows fast traversal of list of encaps attached to nhe under rcu read
lock protection.
- Take encap_table_lock when accessing encap entries in neigh update and
neigh stats update code to protect from concurrent encap entry
insertion or removal.
This approach leads to potential race condition when neigh update and
neigh stats update code can access encap and flow entries that are not
fully initialized or are being destroyed, or neigh can change state
without updating encaps that are created concurrently. Prevent these
issues by following changes in flow and encap initialization:
- Extend mlx5e_tc_flow with 'init_done' completion. Modify neigh update
to wait for both encap and flow completions to prevent concurrent
access to a structure that is being initialized by tc.
- Skip structures that failed during initialization: encaps with
encap_id<0 and flows that don't have OFFLOADED flag set.
- To ensure that no new flows are added to encap when it is being
accessed by neigh update or neigh stats update, take encap_table_lock
mutex.
- To prevent concurrent deletion by tc, ensure that neigh update and
neigh stats update hold references to encap and flow instances while
using them.
With changes presented in this patch set it is now safe to execute tc
concurrently with neigh update and neigh stats update. However, these
two workqueue tasks modify same flow "tmp_list" field to store flows
with reference taken in temporary list to release the references after
update operation finishes and should not be executed concurrently with
each other.
Last 3 patches of this series provide 3 new mlx5 trace points to track
mlx5 tc requests and mlx5 neigh updates.

In order to remove dependency on rtnl lock and allow neigh update workqueue
task to execute concurrently with tc, refactor mlx5e_rep_neigh_update() for
concurrent execution:
- Lock encap table when accessing encap entry to prevent concurrent
changes. To do this properly, the initial encap state check is moved from
mlx5e_rep_neigh_update() into mlx5e_rep_update_flows() to be performed
under encap_tbl_lock protection.
- Wait for encap to be fully initialized before accessing it by means of
'res_ready' completion.
- Add mlx5e_take_all_encap_flows() helper which is used to construct a
temporary list of flows and efi indexes that is used to access current
encap data in flow which can be attached to multiple encaps
simultaneously. Release the flows from temporary list after
encap_tbl_lock critical section. This is necessary because
mlx5e_flow_put() can't be called while holding encap_tbl_lock.
- Modify mlx5e_tc_encap_flows_add() and mlx5e_tc_encap_flows_del() to work
with user-provided list of flows built by mlx5e_take_all_encap_flows(),
instead of traversing encap flow list directly.
This is first step in complex neigh update refactoring, which is finished
by following commit in this series.

used to synchronize with netevent handler function, which is called from bh
context and cannot use rtnl lock for synchronization. Take lock in encap
entry attach function to prevent concurrent modifications of neigh update

Taking the encap lock when creating new nhe introduces a problem that we
need to allocate new entry with sleeping GFP_KERNEL flag while holding a
spinlock. However, since previous patch in this series has already
converted lookup in netevent handler function to user rcu read lock instead
of encap lock, we can safely convert the lock type to mutex.

Neigh entry has reference counter, however it is only used when scheduling
neigh update event. In all other cases reference to neigh entry is not
taken while working with it. Neigh code relies on synchronization provided
by rtnl lock and uses encap list size as implicit reference counter.
To remove dependency on rtnl lock, always take reference to neigh entry
while using it. Remove neigh entry from hash table and delete it only when
reference counter reaches zero. This can result spurious neigh update
events, when there is an event on entry that has zero encaps attached.
However, such events are rare and properly handled by neigh update handler.
Extend encap entry with reference to neigh hash entry in order to be able
to directly release it when encap is detached, instead of lookup nhe by key
through hash table. Extend nhe with reference to device priv structure to
guarantee correctness when nhe is used with stack devices, bond setup, in
which case it is non-trivial to determine correct device when releasing the
nhe.

[Why]
The only place where state->max_bpc is updated on the connector is
at the start of atomic check during drm_atomic_connector_check. It
isn't updated when adding the connectors to the atomic state after
the fact. It also doesn't necessarily reflect the right value when
called in amdgpu during mode validation outside of atomic check.
This can cause the wrong bpc to be used even if the max_requested_bpc
is the correct value.
[How]
Don't rely on state->max_bpc reflecting the real bpc value and just
do the min(...) based on display info bpc and max_requested_bpc.

cpsw_remove_dt() before calling platform_set_drvdata(). This is an
issue as cpsw_remove_dt() uses platform_get_drvdata() to retrieve the

fixes it by calling platform_set_drvdata() earlier in the probe.

commit a90118c445cc ("x86/boot: Save fields explicitly, zero out everything
else") had two errors:
* It preserved boot_params.acpi_rsdp_addr, and
* It failed to preserve boot_params.hdr
Therefore, zero out acpi_rsdp_addr, and preserve hdr.
Fixes: a90118c445cc ("x86/boot: Save fields explicitly, zero out everything else")
