Bluetooth: Ignore HCI_ERROR_CANCELLED_BY_HOST on adv set terminated event

This event is received when the controller stops advertising,
specifically for these three reasons:
(a) Connection is successfully created (success).
(b) Timeout is reached (error).
(c) Number of advertising events is reached (error).
(*) This event is NOT generated when the host stops the advertisement.
Refer to the BT spec ver 5.3 vol 4 part E sec 7.7.65.18. Note that the
section was revised from BT spec ver 5.0 vol 2 part E sec 7.7.65.18
which was ambiguous about (*).

Some chips (e.g. RTL8822CE) send this event when the host stops the
advertisement with status = HCI_ERROR_CANCELLED_BY_HOST (due to (*)
above). This is treated as an error and the advertisement will be
removed and userspace will be informed via MGMT event.

On suspend, we are supposed to temporarily disable advertisements,
and continue advertising on resume. However, due to the behavior
above, the advertisements are removed instead.

This patch returns early if HCI_ERROR_CANCELLED_BY_HOST is received.

Marcel Holtmann [Wed, 27 Oct 2021 23:58:38 +0000 (16:58 -0700)]
Bluetooth: Add helper for serialized HCI command execution

The usage of __hci_cmd_sync() within the hdev->setup() callback allows for
a nice and simple serialized execution of HCI commands. More importantly
it allows for result processing before issueing the next command.

With the current usage of hci_req_run() it is possible to batch up
commands and execute them, but it is impossible to react to their
results or errors.

This is an attempt to generalize the hdev->setup() handling and provide
a simple way of running multiple HCI commands from a single function
context.

There are multiple struct work that are decdicated to certain tasks
already used right now. It is add a lot of bloat to hci_dev struct and
extra handling code. So it might be possible to put all of these behind
a common HCI command infrastructure and just execute the HCI commands
from the same work context in a serialized fashion.

For example updating the white list and resolving list can be done now
without having to know the list size ahead of time. Also preparing for
suspend or resume shouldn't require a state machine anymore. There are
other tasks that should be simplified as well.

Bluetooth: Fix removing adv when processing cmd complete

If we remove one instance of adv using Set Extended Adv Enable, there
is a possibility of issue occurs when processing the Command Complete
event. Especially, the adv_info might not be found since we already
remove it in hci_req_clear_adv_instance() -> hci_remove_adv_instance().
If that's the case, we will mistakenly proceed to remove all adv
instances instead of just one single instance.

This patch fixes the issue by checking the content of the HCI command
instead of checking whether the adv_info is found.

5) Bridge offload: Pop PVID VLAN header on egress miss

Vlad Buslov says:
=================

With current architecture of mlx5 bridge offload it is possible for a
packet to match in ingress table by source MAC (resulting VLAN header push
in case of port with configured PVID) and then miss in egress table when
destination MAC is not in FDB. Due to the lack of hardware learning in
NICs, this, in turn, results packet going to software data path with PVID
VLAN already added by hardware. This doesn't break software bridge since it
accepts either untagged packets or packets with any provisioned VLAN on
ports with PVID, but can break ingress TC, if affected part of Ethernet
header is matched by classifier.

Improve compatibility with software TC by restoring the packet header on
egress miss. Effectively, this change implements atomicity of mlx5 bridge
offload implementation - packet is either modified and redirected to
destination port or appears unmodified in software.

net/mlx5e: TC, Refactor sample offload error flow

Refactor sample unoffload to be symmetric to sample offload.
Use the existing del_post_rule() to release the post rule.
Also mlx5e_tc_sample_unoffload() should not return post_rule
which is NULL when post actions are supported.
Sample offload works with this NULL because many places of the
code use IS_ERR() instead of IS_ERR_OR_NULL() to check rule is valid
and when rule is detected as sample offload the code is not using the
rule. Let's be persistent and avoid returning NULL anyway and return the
pre rule, like in CT case, which is not NULL.

3 years agonet/mlx5e: Specify SQ stats struct for mlx5e_open_txqsq()

net/mlx5e: Specify SQ stats struct for mlx5e_open_txqsq()

Let the caller of mlx5e_open_txqsq() directly pass the SQ stats
structure pointer.
This replaces logic involving the qos_queue_group_id parameter,
and helps generalizing its role in the next patch.
