can: fix oops caused by wrong rtnl dellink usage

2016-06-23T08:58:17+00:00

For 'real' hardware CAN devices the netlink interface is used to set CAN
specific communication parameters. Real CAN hardware can not be created nor
removed with the ip tool ...

This patch adds a private dellink function for the CAN device driver interface
that does just nothing.

It's a follow up to commit 993e6f2fd ("can: fix oops caused by wrong rtnl
newlink usage") but for dellink.

can: fix handling of unmodifiable configuration options fix

2016-06-23T08:58:16+00:00

With upstream commit bb208f144cf3f59 (can: fix handling of unmodifiable
configuration options) a new can_validate() function was introduced.

When invoking 'ip link set can0 type can' without any configuration data
can_validate() tries to validate the content without taking into account that
there's totally no content. This patch adds a check for missing content.

can: at91_can: RX queue could get stuck at high bus load

2016-06-20T07:32:40+00:00

At high bus load it could happen that "at91_poll()" enters with all RX
message boxes filled up. If then at the end the "quota" is exceeded as
well, "rx_next" will not be reset to the first RX mailbox and hence the
interrupts remain disabled.

can: c_can: Update D_CAN TX and RX functions to 32 bit - fix Altera Cyclone access

2016-06-20T07:32:40+00:00

When testing CAN write floods on Altera's CycloneV, the first 2 bytes
are sometimes 0x00, 0x00 or corrupted instead of the values sent. Also
observed bytes 4 & 5 were corrupted in some cases.

The D_CAN Data registers are 32 bits and changing from 16 bit writes to
32 bit writes fixes the problem.

Testing performed on Altera CycloneV (D_CAN).  Requesting tests on other
C_CAN & D_CAN platforms.

can: ifi: Increment TX counters only on real transmission

2016-05-09T09:07:28+00:00

Only increment the TX counters in the irq handler if a CAN message
was sent. The current code incremented the counters also if the TX
FIFO empty interrupt happened, which is incorrect.

can: ifi: Treat CAN_CTRLMODE_FD_NON_ISO correctly

2016-05-09T09:07:28+00:00

The CAN_CTRLMODE_FD flag is set for both ISO and BOSCH CANFD mode,
while the CAN_CTRLMODE_FD_NON_ISO is additional flag which is only
set for CANFD-BOSCH mode. Fix the handling of the flags to reflect
this.

can: ifi: Unify timing constants

2016-05-09T09:07:28+00:00

There is no distinction between bittiming constants for the slow and
fast part of the CANFD operation on this controller, so just use one
single bittiming constant set.
