| * | RDMA/cma: Merge cma_get/save_net_infoSean Hefty2013-06-201-55/+69
| | | | | | | | | | | | | | | | | | | | | | | | | | | With the removal of SDP related code, we can merge cma_get_net_info() with cma_save_net_info(), since we're only ever dealing with a single header format.

| * | RDMA/cma: Remove unused SDP related codeSean Hefty2013-06-201-145/+31
| | | | | | | | | | | | | | | | | | | | | | | | The SDP protocol was never merged upstream. Remove unused SDP related code from the RDMA CM. Signed-off-by: Sean Hefty <sean.hefty@intel.com> Signed-off-by: Roland Dreier <roland@purestorage.com>
| * | RDMA/cma: Add support for AF_IB to cma_get_service_id()Sean Hefty2013-06-201-0/+3
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | cma_get_service_id() forms the service ID based on the port space and port number of the rdma_cm_id. Extend the call to support AF_IB, which contains the service ID directly. This will be needed to support any arbitrary SID.

| | | | | | | | | | | | | | | | | | | | | | | | Allow rdma_resolve_route() to handle the case where the user specified the source and destination addresses using AF_IB. Signed-off-by: Sean Hefty <sean.hefty@intel.com> Signed-off-by: Roland Dreier <roland@purestorage.com>
| * | RDMA/cma: Add support for AF_IB to rdma_resolve_addr()Sean Hefty2013-06-201-6/+100
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Allow the user to specify the remote address using AF_IB format. When AF_IB is used, the remote address simply needs to be recorded, and no resolution using ARP is done. The local address may still need to be matched with a local IB device.

| * | RDMA/cma: Do not modify sa_family when setting loopback addressSean Hefty2013-06-201-13/+18
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | cma_resolve_loopback is called after an rdma_cm_id has been bound to a specific sa_family and port. Once the source sa_family for the id has been set, do not modify it. Only the actual IP address portion of the source address needs to be set. As part of this fix, we can simplify setting the source address by moving the loopback address assignment from cma_resolve_loopback to cma_bind_loopback. cma_bind_loopback is only invoked when the source address is the loopback address. Finally, add loopback support for AF_IB as part of the change. Signed-off-by: Sean Hefty <sean.hefty@intel.com> Signed-off-by: Roland Dreier <roland@purestorage.com>

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Modify rdma_bind_addr to allow the user to specify AF_IB when binding to a device. AF_IB indicates that the user is not mapping an IP address to the native IB addressing.

| * | RDMA/cma: Update port reservation to support AF_IBSean Hefty2013-06-201-21/+86
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The AF_IB uses a 64-bit service id (SID), which the user can control through the use of a mask. The rdma_cm will assign values to the unmasked portions of the SID based on the selected port space and port number. Because the IB spec divides the SID range into several regions, a SID/mask combination may fall into one of the existing port space ranges as defined by the RDMA CM IP Annex. Map the AF_IB SID to the correct RDMA port space. Signed-off-by: Sean Hefty <sean.hefty@intel.com> Signed-off-by: Roland Dreier <roland@purestorage.com>

The only difference from the one I made the other day is that this has Eliezer's interface renames and the timeout handling changes made based upon your feedback, as well as a few bug fixes that have trickeled in. Highlights: 1) Low latency device polling, eliminating the cost of interrupt handling and context switches. Allows direct polling of a network device from socket operations, such as recvmsg() and poll(). Currently ixgbe, mlx4, and bnx2x support this feature. Full high level description, performance numbers, and design in commit 0a4db187a999 ("Merge branch 'll_poll'") From Eliezer Tamir. 2) With the routing cache removed, ip_check_mc_rcu() gets exercised more than ever before in the case where we have lots of multicast addresses. Use a hash table instead of a simple linked list, from Eric Dumazet. 3) Add driver for Atheros CQA98xx 802.11ac wireless devices, from Bartosz Markowski, Janusz Dziedzic, Kalle Valo, Marek Kwaczynski, Marek Puzyniak, Michal Kazior, and Sujith Manoharan. 4) Support reporting the TUN device persist flag to userspace, from Pavel Emelyanov. 5) Allow controlling network device VF link state using netlink, from Rony Efraim. 6) Support GRE tunneling in openvswitch, from Pravin B Shelar. 7) Adjust SOCK_MIN_RCVBUF and SOCK_MIN_SNDBUF for modern times, from Daniel Borkmann and Eric Dumazet. 8) Allow controlling of TCP quickack behavior on a per-route basis, from Cong Wang. 9) Several bug fixes and improvements to vxlan from Stephen Hemminger, Pravin B Shelar, and Mike Rapoport. In particular, support receiving on multiple UDP ports. 10) Major cleanups, particular in the area of debugging and cookie lifetime handline, to the SCTP protocol code. From Daniel Borkmann. 11) Allow packets to cross network namespaces when traversing tunnel devices. From Nicolas Dichtel. 12) Allow monitoring netlink traffic via AF_PACKET sockets, in a manner akin to how we monitor real network traffic via ptype_all. From Daniel Borkmann. 13) Several bug fixes and improvements for the new alx device driver, from Johannes Berg. 14) Fix scalability issues in the netem packet scheduler's time queue, by using an rbtree. From Eric Dumazet. 15) Several bug fixes in TCP loss recovery handling, from Yuchung Cheng. 16) Add support for GSO segmentation of MPLS packets, from Simon Horman. 17) Make network notifiers have a real data type for the opaque pointer that's passed into them. Use this to properly handle network device flag changes in arp_netdev_event(). From Jiri Pirko and Timo Teräs. 18) Convert several drivers over to module_pci_driver(), from Peter Huewe. 19) tcp_fixup_rcvbuf() can loop 500 times over loopback, just use a O(1) calculation instead. From Eric Dumazet. 20) Support setting of explicit tunnel peer addresses in ipv6, just like ipv4. From Nicolas Dichtel. 21) Protect x86 BPF JIT against spraying attacks, from Eric Dumazet. 22) Prevent a single high rate flow from overruning an individual cpu during RX packet processing via selective flow shedding. From Willem de Bruijn. 23) Don't use spinlocks in TCP md5 signing fast paths, from Eric Dumazet. 24) Don't just drop GSO packets which are above the TBF scheduler's burst limit, chop them up so they are in-bounds instead. Also from Eric Dumazet. 25) VLAN offloads are missed when configured on top of a bridge, fix from Vlad Yasevich. 26) Support IPV6 in ping sockets. From Lorenzo Colitti. 27) Receive flow steering targets should be updated at poll() time too, from David Majnemer. 28) Fix several corner case regressions in PMTU/redirect handling due to the routing cache removal, from Timo Teräs. 29) We have to be mindful of ipv4 mapped ipv6 sockets in upd_v6_push_pending_frames(). From Hannes Frederic Sowa. 30) Fix L2TP sequence number handling bugs, from James Chapman." * git://git.kernel.org/pub/scm/linux/kernel/git/davem/net-next: (1214 commits) drivers/net: caif: fix wrong rtnl_is_locked() usage drivers/net: enic: release rtnl_lock on error-path vhost-net: fix use-after-free in vhost_net_flush net: mv643xx_eth: do not use port number as platform device id net: sctp: confirm route during forward progress virtio_net: fix race in RX VQ processing virtio: support unlocked queue poll net/cadence/macb: fix bug/typo in extracting gem_irq_read_clear bit Documentation: Fix references to defunct linux-net@vger.kernel.org net/fs: change busy poll time accounting net: rename low latency sockets functions to busy poll bridge: fix some kernel warning in multicast timer sfc: Fix memory leak when discarding scattered packets sit: fix tunnel update via netlink dt:net:stmmac: Add dt specific phy reset callback support. dt:net:stmmac: Add support to dwmac version 3.610 and 3.710 dt:net:stmmac: Allocate platform data only if its NULL. net:stmmac: fix memleak in the open method ipv6: rt6_check_neigh should successfully verify neigh if no NUD information are available net: ipv6: fix wrong ping_v6_sendmsg return value ...

In 'net' we added a dynamic memory allocation to nl80211_dump_wiphy() to fix a race that Linus reported. Meanwhile in 'net-next' the handlers were converted to use pre and post doit handlers which use a flag to determine whether to hold the RTNL mutex around the operation. However, the dump handlers to not use this logic. Instead they have to explicitly do the locking. There were apparent bugs in the conversion of nl80211_dump_wiphy() in that we were not dropping the RTNL mutex in all the return paths, and it seems we very much should be doing so. So I fixed that whilst handling the overlapping changes. To simplify the initial returns, I take the RTNL mutex after we try to allocate 'tb'. Signed-off-by: David S. Miller <davem@davemloft.net>

When this isn't done, the low level driver that created this device can be unloaded before iser has a chance to free all the objects and a such a call may invoke code segment which isn't valid any more and crash.
