* [TIPC]: Fix two minor sparse warnings.Florian Westphal2007-08-02
| | | | | | | | | | fix two warnings generated by sparse: link.c:2386 symbol 'msgcount' shadows an earlier one node.c:244 symbol 'addr_string' shadows an earlier one Signed-off-by: Florian Westphal <fw@strlen.de> Signed-off-by: David S. Miller <davem@davemloft.net>
* [TIPC]: fix tipc_link_create error handlingFlorian Westphal2007-07-31
| | | | | | | | | | | | if printbuf allocation or tipc_node_attach_link() fails, invalid references to the link are left in the associated node and bearer structures. Fix by allocating printbuf early and moving timer initialization and the addition of the new link to the b_ptr->links list after tipc_node_attach_link() succeeded.

* [TIPC]: Optimize stream send routine to avoid fragmentationAllan Stephens2007-07-11
| | | | | | | | | | | | | | | | | | | | This patch enhances TIPC's stream socket send routine so that it avoids transmitting data in chunks that require fragmentation and reassembly, thereby improving performance at both the sending and receiving ends of the connection. The "maximum packet size" hint that records MTU info allows the socket to decide how big a chunk it should send; in the event that the hint has become stale, fragmentation may still occur, but the data will be passed correctly and the hint will be updated in time for the following send. Note: The 66060 byte pseudo-MTU used for intra-node connections requires the send routine to perform an additional check to ensure it does not exceed TIPC"s limit of 66000 bytes of user data per chunk.

* [NET]: cleanup extra semicolonsStephen Hemminger2007-04-26
| | | | | | | | | | | Spring cleaning time... There seems to be a lot of places in the network code that have extra bogus semicolons after conditionals. Most commonly is a bogus semicolon after: switch() { } Signed-off-by: Stephen Hemminger <shemminger@linux-foundation.org> Signed-off-by: David S. Miller <davem@davemloft.net>
* [SK_BUFF]: Introduce skb_copy_to_linear_data{_offset}Arnaldo Carvalho de Melo2007-04-26

* [TIPC]: Remove code bloat introduced by print buffer reworkAllan Stephens2006-10-18
| | | | | | | | | | This patch allows the compiler to optimize out any code that tries to send debugging output to the null print buffer (TIPC_NULL), a capability that was unintentionally broken during the recent print buffer rework.

* [TIPC]: fix printk warningJeff Garzik2006-10-04
| | | | | | | | | | | | | | | | | | gcc spits out this warning: net/tipc/link.c: In function ‘link_retransmit_failure’: net/tipc/link.c:1669: warning: cast from pointer to integer of different size More than a little bit ugly, storing integers in void*, but at least the code is correct, unlike some of the more crufty Linux kernel code found elsewhere. Rather than having two casts to massage the value into u32, it's easier just to have a single cast and use "%lu", since it's just a printk.

* [TIPC] Fixed sk_buff panic caused by tipc_link_bundle_buf (REVISED)Allan Stephens2006-07-03
| | | | | | | | | | | | The recent change to direct inspection of bundle buffer tailroom did not account for the possiblity of unrequested tailroom added by skb_alloc(), thereby allowing a bundle to be created that exceeds the current link MTU. An additional check now ensures that bundling works correctly no matter if the bundle buffer is smaller, larger, or equal to the link MTU.

* [TIPC]: Fixed skb_under_panic caused by tipc_link_bundle_bufAllan Stephens2006-06-29
| | | | | | | | | | | Now determines tailroom of bundle buffer by directly inspection of buffer. Previously, buffer was assumed to have a max capacity equal to the link MTU, but the addition of link MTU negotiation means that the link MTU can increase after the bundle buffer is allocated.

* [TIPC]: Links now validate destination node specified by incoming messages.Allan Stephens2006-06-26
| | | | | | | | | | | | This fix prevents link flopping and name table inconsistency problems arising when a node is assigned a different <Z.C.N> value than it used previously. (Changing the <Z.C.N> value causes other nodes to have two link endpoints sending to the same MAC address using two different destination <Z.C.N> values, requiring the receiving node to filter out the unwanted messages.)

* [TIPC]: Remove inlines from *.cSam Ravnborg2006-03-21
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | With reference to latest discussions on linux-kernel with respect to inline here is a patch for tipc to remove all inlines as used in the .c files. See also chapter 14 in Documentation/CodingStyle. Before: text data bss dec hex filename 102990 5292 1752 110034 1add2 tipc.o Now: text data bss dec hex filename 101190 5292 1752 108234 1a6ca tipc.o This is a nice text size reduction which will improve icache usage. In some cases bigger (> 4 lines) functions where declared inline and used in many places, they are most probarly no longer inlined by gcc resulting in the size reduction. There are several one liners that no longer are declared inline, but gcc should inline these just fine without the inline hint. With this patch applied one warning is added about an unused static function - that was hidded by utilising inline before. The function in question were kept so this patch is solely a inline removal patch.

* [TIPC]: Fix simple sparse warningsSam Ravnborg2006-03-21
| | | | | | | | | | | | | Tried to run the new tipc stack through sparse. Following patch fixes all cases where 0 was used as replacement of NULL. Use NULL to document this is a pointer and to silence sparse. This brough sparse warning count down with 127 to 24 warnings.
