net/tipc: use %*phC to dump small buffers in hex form

2013-07-12T00:03:36Z

Instead of passing each byte by stack let's use nice specifier for that. Signed-off-by: Andy Shevchenko Signed-off-by: David S. Miller

tipc: remove dev_base_lock use from enable_bearer

2013-06-17T22:53:01Z

Convert enable_bearer() to RCU locking with dev_get_by_name(). Based on a similar changeset in commit 840a185d ["aoe: remove dev_base_lock use from aoecmd_cfg_pkts()"] -- quoting that: "dev_base_lock is the legacy way to lock the device list, and is planned to disappear. (writers hold RTNL, readers hold RCU lock)" Signed-off-by: Ying Xue Signed-off-by: Paul Gortmaker Signed-off-by: David S. Miller

tipc: fix wrong return value for link_send_sections_long routine

2013-06-17T22:53:01Z

When skb buffer cannot be allocated in link_send_sections_long(), -ENOMEM error code instead of -EFAULT should be returned to its caller. Signed-off-by: Ying Xue Signed-off-by: Paul Gortmaker Signed-off-by: David S. Miller

tipc: make tipc_link_send_sections_fast exit earlier

2013-06-17T22:53:01Z

Once message build request function returns invalid code, the process of sending message cannot continue. So in case of message build failure, tipc_link_send_sections_fast() should return immediately. Signed-off-by: Ying Xue Signed-off-by: Paul Gortmaker Signed-off-by: David S. Miller

tipc: enhance priority of link protocol packet

2013-06-17T22:53:01Z

pfifo_fast is set as default traffic class queueing discipline. This queue has three so called "bands". Within each band, FIFO rules apply. However, as long as there are packets waiting in band 0, band 1 won't be processed. Now all kind of TIPC type packet priorities are never set, that is, their priorities are 0, so they are mapped to band 1 of pfifo_fast qdisc. But, especially during link congestion, if link protocol packet can be sent out as earlier as possible than other type of packets so that protocol packet can arrive at peer endpoint in time, the peer will timely reset its link timeout timer to keep the link alive. So enhancing the priority of link protocol packets can meet the specific demand to avoid unnecessary link reset due to a transient link congestion.

tipc: cosmetic realignment of function arguments

2013-06-17T22:53:01Z

No runtime code changes here. Just a realign of the function arguments to start where the 1st one was, and fit as many args as can be put in an 80 char line. Signed-off-by: Paul Gortmaker Signed-off-by: David S. Miller

tipc: save sock structure pointer instead of void pointer to tipc_port

2013-06-17T22:53:01Z

Directly save sock structure pointer instead of void pointer to avoid unnecessary cast conversions. Signed-off-by: Ying Xue Signed-off-by: Jon Maloy Signed-off-by: Paul Gortmaker Signed-off-by: David S. Miller

tipc: convert config_lock from spinlock to mutex

2013-06-17T22:53:01Z

As the configuration server is now running under process context, it's unnecessary for us to have a spinlock serializing the TIPC configuration process. Instead, we replace it with a mutex lock, which gives us more freedom. For instance, we can now call pre-emptable functions within the protected area.

tipc: rename tipc_createport_raw to tipc_createport

2013-06-17T22:53:01Z

After the removal of the native API, there is now only one way to to create a TIPC port instance -- the function tipc_createport_raw(). We make it more readable by renaming it to tipc_createport().

tipc: remove user_port instance from tipc_port structure

2013-06-17T22:53:00Z

After the native API has been completely removed, the 'user_port' field in struct tipc_port becomes unused, and can be removed. As a consequence, the "usrmem" argument in tipc_msg_build() is no longer needed, and so we remove that one too.
