IB/core: Create QP1 using the pkey index which contains the default pkey

2013-07-31T21:15:17+00:00

Currently, QP1 is created using pkey index 0. This patch simply looks for the index containing the default pkey, rather than hard-coding pkey index 0. This change will have no effect in native mode, since QP0 and QP1 are created before the SM configures the port, so pkey table will still be the default table defined by the IB Spec, in C10-123: "If non-volatile storage is not used to hold P_Key Table contents, then if a PM (Partition Manager) is not present, and prior to PM initialization of the P_Key Table, the P_Key Table must act as if it contains a single valid entry, at P_Key_ix = 0, containing the default partition key. All other entries in the P_Key Table must be invalid." Thus, in the native mode case, the driver will find the default pkey at index 0 (so it will be no different than the hard-coding). However, in SR-IOV mode, for VFs, the pkey table may be paravirtualized, so that the VF's pkey index zero may not necessarily be mapped to the real pkey index 0. For VFs, therefore, it is important to find the virtual index which maps to the real default pkey. This commit does the following for QP1 creation: 1. Find the pkey index containing the default pkey, and use that index if found. ib_find_pkey() returns the index of the limited-membership default pkey (0x7FFF) if the full-member default pkey is not in the table. 2. If neither form of the default pkey is found, use pkey index 0 (previous behavior). Signed-off-by: Jack Morgenstein Signed-off-by: Or Gerlitz Reviewed-by: Sean Hefty Signed-off-by: Roland Dreier

RDMA/cma: Fix accessing invalid private data for UD

2013-07-31T07:50:40+00:00

If a application is using AF_IB with a UD QP, but does not provide any private data, we will end up accessing invalid memory. Check for this case and handle it appropriately. Signed-off-by: Sean Hefty Signed-off-by: Roland Dreier

RDMA/cma: Fix gcc warning

2013-07-30T23:11:22+00:00

Building cma.o triggers this gcc warning: drivers/infiniband/core/cma.c: In function ‘rdma_resolve_addr’: drivers/infiniband/core/cma.c:465:23: warning: ‘port’ may be used uninitialized in this function [-Wmaybe-uninitialized] drivers/infiniband/core/cma.c:426:5: note: ‘port’ was declared here This is a false positive, as "port" will always be initialized if we're at "found". But if we assign to "id_priv->id.port_num" directly, we can drop "port". That will, obviously, silence gcc. Signed-off-by: Paul Bolle Signed-off-by: Sean Hefty Signed-off-by: Roland Dreier

Pull networking updates from David Miller: "This is a re-do of the net-next pull request for the current merge window. 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 ...

IB/uverbs: Use get_unused_fd_flags(O_CLOEXEC) instead of get_unused_fd()

2013-07-08T18:15:45+00:00

The macro get_unused_fd() is used to allocate a file descriptor with default flags. Those default flags (0) can be "unsafe": O_CLOEXEC must be used by default to not leak file descriptor across exec(). Replace calls to get_unused_fd() in uverbs with calls to get_unused_fd_flags(O_CLOEXEC). Inheriting uverbs fds across exec() cannot be used to do anything useful.

drivers: avoid format string in dev_set_name

2013-07-03T23:07:41+00:00

Calling dev_set_name with a single paramter causes it to be handled as a format string. Many callers are passing potentially dynamic string content, so use "%s" in those cases to avoid any potential accidents, including wrappers like device_create*() and bdi_register().
