canfd: add support for CAN FD in CAN_RAW sockets

2012-06-19T19:40:08+00:00

- introduce a new sockopt CAN_RAW_FD_FRAMES to allow CAN FD frames - handle CAN frames and CAN FD frames simultaneously when enabled Signed-off-by: Oliver Hartkopp Signed-off-by: Marc Kleine-Budde

net: remove skb_orphan_try()

2012-06-15T22:30:15+00:00

Orphaning skb in dev_hard_start_xmit() makes bonding behavior unfriendly for applications sending big UDP bursts : Once packets pass the bonding device and come to real device, they might hit a full qdisc and be dropped. Without orphaning, the sender is automatically throttled because sk->sk_wmemalloc reaches sk->sk_sndbuf (assuming sk_sndbuf is not too big) We could try to defer the orphaning adding another test in dev_hard_start_xmit(), but all this seems of little gain, now that BQL tends to make packets more likely to be parked in Qdisc queues instead of NIC TX ring, in cases where performance matters.

can: remove references to berlios mailinglist

2011-10-17T23:22:46+00:00

The BerliOS project, which currently hosts our mailinglist, will close with the end of the year. Now take the chance and remove all occurrences of the mailinglist address from the source files. Signed-off-by: Marc Kleine-Budde Signed-off-by: David S. Miller

can: make struct can_proto const

2011-05-04T21:08:36+00:00

commit 53914b67993c724cec585863755c9ebc8446e83b had the same message. That commit did put everything in place but did not make can_proto const itself. Signed-off-by: Kurt Van Dijck Acked-by: Oliver Hartkopp Signed-off-by: David S. Miller

can: add missing socket check in can/raw release

2011-04-20T19:37:59+00:00

v2: added space after 'if' according code style. We can get here with a NULL socket argument passed from userspace, so we need to handle it accordingly. Thanks to Dave Jones pointing at this issue in net/can/bcm.c Signed-off-by: Oliver Hartkopp Signed-off-by: David S. Miller

can: make struct proto const

2011-03-28T06:34:59+00:00

can_ioctl is the only reason for struct proto to be non-const. script/check-patch.pl suggests struct proto be const. Setting the reference to the common can_ioctl() in all CAN protocols directly removes the need to make the struct proto writable in af_can.c Signed-off-by: Kurt Van Dijck Signed-off-by: Oliver Hartkopp Signed-off-by: David S.

can: test size of struct sockaddr in sendmsg

2011-01-16T04:56:42+00:00

This patch makes the CAN socket code conform to the manpage of sendmsg. Signed-off-by: Kurt Van Dijck Acked-by: Oliver Hartkopp Signed-off-by: David S. Miller

can-raw: add msg_flags to distinguish local traffic

2010-10-21T11:27:03+00:00

CAN has no addressing scheme. It is currently impossible for userspace to tell is a received CAN frame comes from another process on the local host, or from a remote CAN device. This patch add support for userspace applications to distinguish between 'own', 'local' and 'remote' CAN traffic. The distinction is made by returning flags in msg->msg_flags in the call to recvmsg(). The added documentation explains the introduced flags.

net: simplify flags for tx timestamping

2010-08-19T07:08:30+00:00

This patch removes the abstraction introduced by the union skb_shared_tx in the shared skb data. The access of the different union elements at several places led to some confusion about accessing the shared tx_flags e.g. in skb_orphan_try(). http://marc.info/?l=linux-netdev&m=128084897415886&w=2 Signed-off-by: Oliver Hartkopp Signed-off-by: David S.
