can: introduce CAN midlayer private and allocate it automatically

2019-09-04T11:29:14+00:00

This patch introduces the CAN midlayer private structure ("struct
can_ml_priv") which should be used to hold protocol specific per device
data structures. For now it's only member is "struct can_dev_rcv_lists".

The CAN midlayer private is allocated via alloc_netdev()'s private and
assigned to "struct net_device::ml_priv" during device creation. This is
done transparently for CAN drivers using alloc_candev(). The slcan, vcan
and vxcan drivers which are not using alloc_candev() have been adopted
manually. The memory layout of the netdev_priv allocated via
alloc_candev() will looke like this:

  +-------------------------+
  | driver's priv           |
  +-------------------------+
  | struct can_ml_priv      |
  +-------------------------+
  | array of struct sk_buff |
  +-------------------------+

can: netns: give structs holding the CAN statistics a sensible name

2019-09-04T11:29:13+00:00

This patch renames both "struct s_stats" and "struct s_pstats", to
"struct can_pkg_stats" and "struct can_rcv_lists_stats" to better
reflect their meaning and improve code readability.

The conversion is done with:

	sed -i \
		-e "s/struct s_stats/struct can_pkg_stats/g" \
		-e "s/struct s_pstats/struct can_rcv_lists_stats/g" \
		net/can/*.[ch] \
		include/net/netns/can.h

can: Add SPDX license identifiers for CAN subsystem

2019-07-24T08:31:55+00:00

Add missing SPDX identifiers for the CAN network layer and correct the SPDX
license for two of its include files to make sure the BSD-3-Clause applies
for the entire subsystem.

net: can: Convert timers to use timer_setup()

2017-10-18T11:39:38+00:00

In preparation for unconditionally passing the struct timer_list pointer to
all timer callbacks, switch to using the new timer_setup() and from_timer()
to pass the timer pointer explicitly.

can: complete initial namespace support

2017-04-25T07:04:29+00:00

The statistics and its proc output was not implemented as per-net in the
initial network namespace support by Mario Kicherer (8e8cda6d737d).
This patch adds the missing per-net statistics for the CAN subsystem.

can: initial support for network namespaces

2017-04-04T15:35:58+00:00

This patch adds initial support for network namespaces. The changes only
enable support in the CAN raw, proc and af_can code. GW and BCM still
have their checks that ensure that they are used only from the main
namespace.

The patch boils down to moving the global structures, i.e. the global
filter list and their /proc stats, into a per-namespace structure and passing
around the corresponding "struct net" in a lot of different places.

Changes since v1:
 - rebased on current HEAD (2bfe01e)
 - fixed overlong line
