net: Move {l,t,d}stats allocation to core and convert veth & vrf

2023-11-20T18:15:16+00:00

Move {l,t,d}stats allocation to the core and let netdevs pick the stats
type they need. That way the driver doesn't have to bother with error
handling (allocation failure checking, making sure free happens in the
right spot, etc) - all happening in the core.

net, vrf: Move dstats structure to core

2023-11-20T18:15:15+00:00

Just move struct pcpu_dstats out of the vrf into the core, and streamline
the field names slightly, so they better align with the {t,l}stats ones.

No functional change otherwise. A conversion of the u64s to u64_stats_t
could be done at a separate point in future. This move is needed as we are
moving the {t,l,d}stats allocation/freeing to the core.

net: Add MDB get device operation

2023-10-27T09:51:41+00:00

Add MDB net device operation that will be invoked by rtnetlink code in
response to received RTM_GETMDB messages. Subsequent patches will
implement the operation in the bridge and VXLAN drivers.

net: introduce napi_is_scheduled helper

2023-10-19T13:41:31+00:00

We currently have napi_if_scheduled_mark_missed that can be used to
check if napi is scheduled but that does more thing than simply checking
it and return a bool. Some driver already implement custom function to
check if napi is scheduled.

Drop these custom function and introduce napi_is_scheduled that simply
check if napi is scheduled atomically.

Update any driver and code that implement a similar check and instead
use this new helper.

net: Handle bulk delete policy in bridge driver

2023-10-13T09:00:30+00:00

The merge commit 92716869375b ("Merge branch 'br-flush-filtering'")
added support for FDB flushing in bridge driver. The following patches
will extend VXLAN driver to support FDB flushing as well. The netlink
message for bulk delete is shared between the drivers. With the existing
implementation, there is no way to prevent user from flushing with
attributes that are not supported per driver. For example, when VNI will
be added, user will not get an error for flush FDB entries in bridge
with VNI, although this attribute is not relevant for bridge.

As preparation for support of FDB flush in VXLAN driver, move the policy
to be handled in bridge driver, later a new policy for VXLAN will be
added in VXLAN driver. Do not pass 'vid' as part of ndo_fdb_del_bulk(),
as this field is relevant only for bridge.

netdev: replace napi_reschedule with napi_schedule

2023-10-12T00:28:06+00:00

Now that napi_schedule return a bool, we can drop napi_reschedule that
does the same exact function. The function comes from a very old commit
bfe13f54f502 ("ibm_emac: Convert to use napi_struct independent of struct
net_device") and the purpose is actually deprecated in favour of
different logic.

Convert every user of napi_reschedule to napi_schedule.

netdev: make napi_schedule return bool on NAPI successful schedule

2023-10-12T00:28:05+00:00

Change napi_schedule to return a bool on NAPI successful schedule.
This might be useful for some driver to do additional steps after a
NAPI has been scheduled.

net/core: Introduce netdev_core_stats_inc()

2023-10-11T09:07:40+00:00

Although there is a kfree_skb_reason() helper function that can be used to
find the reason why this skb is dropped, but most callers didn't increase
one of rx_dropped, tx_dropped, rx_nohandler and rx_otherhost_dropped.

For the users, people are more concerned about why the dropped in ip
is increasing.

Introduce netdev_core_stats_inc() for trace the caller of
dev_core_stats_*_inc().

Also, add __code to netdev_core_stats_alloc(), as it's called with small
probability. And add noinline make sure netdev_core_stats_inc was never
inlined.
