Drivers need not be concerned about balancing changes to the usage

is unbound from its interface. As a corollary, drivers must not call
any of the ``usb_autopm_*`` functions after their ``disconnect``
routine has returned.
Drivers must be careful to balance their overall changes to the usage
counter. Unbalanced "get"s will remain in effect when a driver is
unbound from its interface, preventing the device from going into
runtime suspend should the interface be bound to a driver again. On
the other hand, drivers are allowed to achieve this balance by calling
the ``usb_autopm_*`` functions even after their ``disconnect`` routine
has returned -- say from within a work-queue routine -- provided they
retain an active reference to the interface (via ``usb_get_intf`` and
``usb_put_intf``).
Drivers using the async routines are responsible for their own
synchronization and mutual exclusion.

==================
BPF Flow Dissector
==================
Overview
========
Flow dissector is a routine that parses metadata out of the packets. It's
used in the various places in the networking subsystem (RFS, flow hash, etc).
BPF flow dissector is an attempt to reimplement C-based flow dissector logic
in BPF to gain all the benefits of BPF verifier (namely, limits on the
number of instructions and tail calls).
API
===
BPF flow dissector programs operate on an ``__sk_buff``. However, only the
limited set of fields is allowed: ``data``, ``data_end`` and ``flow_keys``.
``flow_keys`` is ``struct bpf_flow_keys`` and contains flow dissector input
and output arguments.
The inputs are:
* ``nhoff`` - initial offset of the networking header
* ``thoff`` - initial offset of the transport header, initialized to nhoff
* ``n_proto`` - L3 protocol type, parsed out of L2 header
Flow dissector BPF program should fill out the rest of the ``struct
bpf_flow_keys`` fields. Input arguments ``nhoff/thoff/n_proto`` should be
also adjusted accordingly.
The return code of the BPF program is either BPF_OK to indicate successful
dissection, or BPF_DROP to indicate parsing error.
__sk_buff->data
===============
In the VLAN-less case, this is what the initial state of the BPF flow
dissector looks like::
+------+------+------------+-----------+
| DMAC | SMAC | ETHER_TYPE | L3_HEADER |
+------+------+------------+-----------+
^
|
+-- flow dissector starts here
.. code:: c
skb->data + flow_keys->nhoff point to the first byte of L3_HEADER
flow_keys->thoff = nhoff
flow_keys->n_proto = ETHER_TYPE
In case of VLAN, flow dissector can be called with the two different states.
Pre-VLAN parsing::
+------+------+------+-----+-----------+-----------+
| DMAC | SMAC | TPID | TCI |ETHER_TYPE | L3_HEADER |
+------+------+------+-----+-----------+-----------+
^
|
+-- flow dissector starts here
.. code:: c
skb->data + flow_keys->nhoff point the to first byte of TCI
flow_keys->thoff = nhoff
flow_keys->n_proto = TPID
Please note that TPID can be 802.1AD and, hence, BPF program would
have to parse VLAN information twice for double tagged packets.
Post-VLAN parsing::
+------+------+------+-----+-----------+-----------+
| DMAC | SMAC | TPID | TCI |ETHER_TYPE | L3_HEADER |
+------+------+------+-----+-----------+-----------+
^
|
+-- flow dissector starts here
.. code:: c
skb->data + flow_keys->nhoff point the to first byte of L3_HEADER
flow_keys->thoff = nhoff
flow_keys->n_proto = ETHER_TYPE
In this case VLAN information has been processed before the flow dissector
and BPF flow dissector is not required to handle it.
The takeaway here is as follows: BPF flow dissector program can be called with
the optional VLAN header and should gracefully handle both cases: when single
or double VLAN is present and when it is not present. The same program
can be called for both cases and would have to be written carefully to
handle both cases.
Reference Implementation
========================
See ``tools/testing/selftests/bpf/progs/bpf_flow.c`` for the reference
implementation and ``tools/testing/selftests/bpf/flow_dissector_load.[hc]``
for the loader. bpftool can be used to load BPF flow dissector program as well.
The reference implementation is organized as follows:
* ``jmp_table`` map that contains sub-programs for each supported L3 protocol
* ``_dissect`` routine - entry point; it does input ``n_proto`` parsing and
does ``bpf_tail_call`` to the appropriate L3 handler
Since BPF at this point doesn't support looping (or any jumping back),
jmp_table is used instead to handle multiple levels of encapsulation (and
IPv6 options).
Current Limitations
===================
BPF flow dissector doesn't support exporting all the metadata that in-kernel
C-based implementation can export. Notable example is single VLAN (802.1Q)
and double VLAN (802.1AD) tags. Please refer to the ``struct bpf_flow_keys``
for a set of information that's currently can be exported from the BPF context.
