2011-10-24be2net: refactor VF setup/teardown code into be_vf_setup/clear()Sathya Perla3-152/+147
Currently the code for VF setup/teardown done by a PF (if_create, mac_add_config, link_status_query etc) is scattered; this patch refactors this code into be_vf_setup() and be_vf_clear(). The if_create/if_destroy/mac_addr_query cmds are now called after the MCCQ is created; so these cmds are now modified to use the MCCQ instead of MBOX.

2011-10-24be2net: add vlan/rx-mode/flow-control config to be_setup()Sathya Perla1-65/+56
When a card is reset due to EEH error recovery or due to a suspend, rx-mode config (promisc/mc) is not being sent to the FW. be_setup() is called in these flows and is the best place for such config/re-config cmds. Hence include rx-mode, vlan and flow-control config in be_setup(). Signed-off-by: Sathya Perla <sathya.perla@emulex.com> Signed-off-by: David S. Miller <davem@davemloft.net>

2011-10-24ipv4: tcp: fix TOS value in ACK messages sent from TIME_WAITEric Dumazet5-9/+15
There is a long standing bug in linux tcp stack, about ACK messages sent on behalf of TIME_WAIT sockets. In the IP header of the ACK message, we choose to reflect TOS field of incoming message, and this might break some setups. Example of things that were broken : - Routing using TOS as a selector - Firewalls - Trafic classification / shaping We now remember in timewait structure the inet tos field and use it in ACK generation, and route lookup. Notes : - We still reflect incoming TOS in RST messages. - We could extend MuraliRaja Muniraju patch to report TOS value in netlink messages for TIME_WAIT sockets. - A patch is needed for IPv6 Signed-off-by: Eric Dumazet <eric.dumazet@gmail.com> Signed-off-by: David S.

2011-10-24rtnetlink: Add missing manual netlink notification in dev_change_net_namespacesEric W. Biederman1-0/+1
Renato Westphal noticed that since commit a2835763e130c343ace5320c20d33c281e7097b7 "rtnetlink: handle rtnl_link netlink notifications manually" was merged we no longer send a netlink message when a networking device is moved from one network namespace to another. Fix this by adding the missing manual notification in dev_change_net_namespaces. Since all network devices that are processed by dev_change_net_namspaces are in the initialized state the complicated tests that guard the manual rtmsg_ifinfo calls in rollback_registered and register_netdevice are unnecessary and we can just perform a plain notification.

The commit f39925dbde7788cfb96419c0f092b086aa325c0f (ipv4: Cache learned redirect information in inetpeer.) removed some ICMP packet validations which are required by RFC 1122, section 3.2.2.2: ... A Redirect message SHOULD be silently discarded if the new gateway address it specifies is not on the same connected (sub-) net through which the Redirect arrived [INTRO:2, Appendix A], or if the source of the Redirect is not the current first-hop gateway for the specified destination (see Section 3.3.1).

2011-10-24net: hold sock reference while processing tx timestampsRichard Cochran3-4/+17
The pair of functions, * skb_clone_tx_timestamp() * skb_complete_tx_timestamp() were designed to allow timestamping in PHY devices. The first function, called during the MAC driver's hard_xmit method, identifies PTP protocol packets, clones them, and gives them to the PHY device driver. The PHY driver may hold onto the packet and deliver it at a later time using the second function, which adds the packet to the socket's error queue. As pointed out by Johannes, nothing prevents the socket from disappearing while the cloned packet is sitting in the PHY driver awaiting a timestamp. This patch fixes the issue by taking a reference on the socket for each such packet. In addition, the comments regarding the usage of these function are expanded to highlight the rule that PHY drivers must use skb_complete_tx_timestamp() to release the packet, in order to release the socket reference, too. These functions first appeared in v2.6.36.

2011-10-21macvtap: Fix the minor device number allocationEric W. Biederman2-16/+72
On systems that create and delete lots of dynamic devices the 31bit linux ifindex fails to fit in the 16bit macvtap minor, resulting in unusable macvtap devices. I have systems running automated tests that that hit this condition in just a few days. Use a linux idr allocator to track which mavtap minor numbers are available and and to track the association between macvtap minor numbers and macvtap network devices. Remove the unnecessary unneccessary check to see if the network device we have found is indeed a macvtap device. With macvtap specific data structures it is impossible to find any other kind of networking device. Increase the macvtap minor range from 65536 to the full 20 bits that is supported by linux device numbers. It doesn't solve the original problem but there is no penalty for a larger minor device range. Signed-off-by: Eric W. Biederman <ebiederm@xmission.com> Signed-off-by: David S.

2011-10-20myri10ge: fix truesize underestimationEric Dumazet1-1/+2
skb->truesize must account for allocated memory, not the used part of it. Doing this work is important to avoid unexpected OOM situations.

2011-10-20igbvf: fix truesize underestimationEric Dumazet1-1/+1
igbvf allocates half a page per skb fragment. We must account PAGE_SIZE/2 increments on skb->truesize, not the actual frag length. Signed-off-by: Eric Dumazet <eric.dumazet@gmail.com> CC: Jeff Kirsher <jeffrey.t.kirsher@intel.com> Signed-off-by: David S. Miller <davem@davemloft.net>
2011-10-20pktgen: remove ndelay() callEric Dumazet1-4/+7
Daniel Turull reported inaccuracies in pktgen when using low packet rates, because we call ndelay(val) with values bigger than 20000. Instead of calling ndelay() for delays < 100us, we can instead loop calling ktime_now() only.
