2010-09-07ibmveth: Add rx_copybreakSantiago Leon
For small packets, create a new skb and copy the packet into it so we avoid tearing down and creating a TCE entry. Signed-off-by: Anton Blanchard <anton@samba.org> Signed-off-by: Santiago Leon <santil@linux.vnet.ibm.com> Signed-off-by: David S. Miller <davem@davemloft.net>
2010-09-07ibmveth: Add tx_copybreakSantiago Leon
Use the existing bounce buffer if we send a buffer under a certain size. This saves the overhead of a TCE map/unmap. I can't see any reason for the wmb() in the bounce buffer case, if we need a barrier it will be before we call h_send_logical_lan but we have nothing in the common case. Remove it.

2010-09-07ibmveth: Remove LLTXSantiago Leon
The ibmveth adapter needs locking in the transmit routine to protect the bounce_buffer but it sets LLTX and forgets to add any of its own locking. Just remove the deprecated LLTX option. Remove the stats lock in the process. Signed-off-by: Anton Blanchard <anton@samba.org> Signed-off-by: Santiago Leon <santil@linux.vnet.ibm.com> Signed-off-by: David S. Miller <davem@davemloft.net>
2010-09-07ibmveth: batch rx buffer replacementSantiago Leon
At the moment we try and replenish the receive ring on every rx interrupt. We even have a pool->threshold but aren't using it. To limit the maximum latency incurred when refilling, change the threshold from 1/2 to 7/8 and reduce the largest rx pool from 768 buffers to 512 which should be more than enough.

2010-09-07tipc: Fix misleading error code when enabling Ethernet bearersAllan Stephens
Cause TIPC to return EAGAIN if it is unable to enable a new Ethernet bearer because one or more recently disabled Ethernet bearers are temporarily consuming resources during shut down. (The previous error code, EDQUOT, is now returned only if all available Ethernet bearer data structures are fully enabled at the time the request to enable an additional bearer is received.)

2010-09-07tipc: Ensure outgoing messages on Ethernet have sufficient headroomAllan Stephens
Add code to expand the headroom of an outgoing TIPC message if the sk_buff has insufficient room to hold the header for the associated Ethernet device. This change is necessary to ensure that messages TIPC does not create itself (eg. incoming messages that are being routed to another node) do not cause problems, since TIPC has no control over the amount of headroom available in such messages.

2010-09-07tipc: Minor optimizations to name table translation codeAllan Stephens
Optimizes TIPC's name table translation code to avoid unnecessary manipulation of the node address field of the resulting port id when name translation fails. This change is possible because a valid port id cannot have a reference field of zero, so examining the reference only is sufficient to determine if the translation was successful.

2010-09-06r8169: fix rx checksum offloadEric Dumazet
While porting GRO to r8169, I found this driver has a bug in its rx path. All skbs given to network stack had their ip_summed set to CHECKSUM_NONE, while hardware said they had correct TCP/UDP checksums. The reason is driver sets skb->ip_summed on the original skb before the copy eventually done by copybreak. The fresh skb gets the ip_summed = CHECKSUM_NONE value, forcing network stack to recompute checksum, and preventing my GRO patch to work. Fix is to make the ip_summed setting after skb copy. Note : rx_copybreak current value is 16383, so all frames are copied... Signed-off-by: Eric Dumazet <eric.dumazet@gmail.com> Acked-by: Francois Romieu <romieu@fr.zoreil.com> Signed-off-by: David S.

2010-09-03net: remove two kmemcheck annotationsEric Dumazet
__alloc_skb() uses a memset() to clear all the beginning of skb, including bitfields contained in 'flags1' & 'flags2'. We dont need any more to use kmemcheck_annotate_bitfield() on these fields.

2010-09-03ipv6: add special mode forwarding=2 to send RS while configured as routerThomas Graf
Similar to accepting router advertisement, the IPv6 stack does not send router solicitations if forwarding is enabled. This patch enables this behavior to be overruled by setting forwarding to the special value 2. Signed-off-by: Thomas Graf <tgraf@infradead.org> Signed-off-by: David S. Miller <davem@davemloft.net>
2010-09-03ipv6: add special mode accept_ra=2 to accept RA while configured as routerThomas Graf
The current IPv6 behavior is to not accept router advertisements while forwarding, i.e. configured as router. This does make sense, a router is typically not supposed to be auto configured. However there are exceptions and we should allow the current behavior to be overwritten. Therefore this patch enables the user to overrule the "if forwarding enabled then don't listen to RAs" rule by setting accept_ra to the special value of 2. An alternative would be to ignore the forwarding switch alltogether and solely accept RAs based on the value of accept_ra. However, I found that if not intended, accepting RAs as a router can lead to strange unwanted behavior therefore we it seems wise to only do so if the user explicitely asks for this behavior.

2010-09-01drivers/net/can/mscan/mpc5xxx_can.c: Add of_node_put to avoid memory leakJulia Lawall
Add a call to of_node_put in the error handling code following a call to of_find_matching_node. This patch also moves the existing call to of_node_put after the call to iounmap in the error handling code, to make it possible to jump to of_node_put without doing iounmap. These appear to be disjoint operations, so the ordering doesn't matter. This patch furthermore changes the -ENODEV result in the error handling code for of_find_matching_node to a return of 0, as found in the error handling code for of_iomap, because the return type of the function is unsigned. The semantic match that finds this problem is as follows: (http://coccinelle.lip6.fr/) // <smpl> @r exists@ local idexpression x; expression E,E1,E2; statement S; @@ *x = (of_find_node_by_path |of_find_node_by_name |of_find_node_by_phandle |of_get_parent |of_get_next_parent |of_get_next_child |of_find_compatible_node |of_match_node |of_find_node_by_type |of_find_node_with_property |of_find_matching_node |of_parse_phandle )(...); ... if (x == NULL) S <... when != x = E *if (...) { ... when != of_node_put(x) when != if (...) { ... of_node_put(x); ... } ( return <+...x...+>; | * return ...; ) } ...> ( E2 = x; | of_node_put(x); ) // </smpl> Signed-off-by: Julia Lawall <julia@diku.dk> Reviewed-by: Wolfram Sang <w.sang@pengutronix.de> Acked-by: Wolfgang Grandegger <wg@grandegger.com> Signed-off-by: David S.
