Pull networking fixes from David Miller: 1) sunhme driver lacks DMA mapping error checks, based upon a report by Meelis Roos. 2) Fix memory leak in mvpp2 driver, from Sudip Mukherjee. 3) DMA memory allocation sizes are wrong in systemport ethernet driver, fix from Florian Fainelli. 4) Fix use after free in mac80211 defragmentation code, from Johannes Berg. 5) Some networking uapi headers missing from Kbuild file, from Stephen Hemminger. 6) TUN driver gets csum_start offset wrong when VLAN accel is enabled, and macvtap has a similar bug, from Herbert Xu. 7) Adjust several tunneling drivers to set dev->iflink after registry, because registry sets that to -1 overwriting whatever we did. From Steffen Klassert. 8) Geneve forgets to set inner tunneling type, causing GSO segmentation to fail on some NICs. From Jesse Gross. 9) Fix several locking bugs in stmmac driver, from Fabrice Gasnier and Giuseppe CAVALLARO. 10) Fix spurious timeouts with NewReno on low traffic connections, from Marcelo Leitner. 11) Fix descriptor updates in enic driver, from Govindarajulu Varadarajan. 12) PPP calls bpf_prog_create() with locks held, which isn't kosher. Fix from Takashi Iwai. 13) Fix NULL deref in SCTP with malformed INIT packets, from Daniel Borkmann. 14) psock_fanout selftest accesses past the end of the mmap ring, fix from Shuah Khan. 15) Fix PTP timestamping for VLAN packets, from Richard Cochran. 16) netlink_unbind() calls in netlink pass wrong initial argument, from Hiroaki SHIMODA. 17) vxlan socket reuse accidently reuses a socket when the address family is different, so we have to explicitly check this, from Marcelo Lietner. 18) Fix missing include in nft_reject_bridge.c breaking the build on ppc and other architectures, from Guenter Roeck. * git://git.kernel.org/pub/scm/linux/kernel/git/davem/net: (75 commits) vxlan: Do not reuse sockets for a different address family smsc911x: power-up phydev before doing a software reset. lib: rhashtable - Remove weird non-ASCII characters from comments net/smsc911x: Fix delays in the PHY enable/disable routines net/smsc911x: Fix rare soft reset timeout issue due to PHY power-down mode netlink: Properly unbind in error conditions. net: ptp: fix time stamp matching logic for VLAN packets. cxgb4 : dcb open-lldp interop fixes selftests/net: psock_fanout seg faults in sock_fanout_read_ring() net: bcmgenet: apply MII configuration in bcmgenet_open() net: bcmgenet: connect and disconnect from the PHY state machine net: qualcomm: Fix dependency ixgbe: phy: fix uninitialized status in ixgbe_setup_phy_link_tnx net: phy: Correctly handle MII ioctl which changes autonegotiation. ipv6: fix IPV6_PKTINFO with v4 mapped net: sctp: fix memory leak in auth key management net: sctp: fix NULL pointer dereference in af->from_addr_param on malformed packet net: ppp: Don't call bpf_prog_create() in ppp_lock net/mlx4_en: Advertize encapsulation offloads features only when VXLAN tunnel is set cxgb4 : Fix bug in DCB app deletion ...

selftests/net: psock_fanout seg faults in sock_fanout_read_ring()

2014-11-12T02:43:34Z

The while loop in sock_fanout_read_ring() checks mmap region bounds after access, causing it to segfault. Fix it to check count before accessing header->tp_status. This problem can be reproduced consistently when the test in run as follows: make -C tools/testing/selftests TARGETS=net run_tests or make run_tests from tools/testing/selftests or make run_test from tools/testing/selftests/net Signed-off-by: Shuah Khan Signed-off-by: David S.

2014-11-04T19:12:25Z

Pull ftracetest fix from Steven Rostedt: "Running the ftracetests on a machine that had the debugfs file system mounted in two locations caused the ftracetests to fail. This is because the ftracetests script does a grep of the /proc/mounts file to find where the debugfs file system is mounted. If it is mounted twice, then the grep returns two lines instead of just one. This causes the ftracetests to get confused and fail. Use "head -1" to only return the first mount point for debugfs" * tag 'ftracetest-3.18-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/rostedt/linux-trace: ftracetest: Take the first debugfs mount found

ftracetest: Take the first debugfs mount found

2014-11-03T18:42:49Z

Running ftracetests on a box that mounted debugfs in two locations made the ftracetests fail. This is because the tests uses a grep of debugfs from the /proc/mounts file to find the debugfs mount point, and then appends "/tracing" to that string to get the tracing directory. If the debugfs directory is mounted twice, then that grep will return two answers and appending "/tracing" to a string with two lines will not work. Use "head -1" to only take the first mount point found. Acked-by: Masami Hiramatsu Signed-off-by: Steven Rostedt

perf probe: Trivial typo fix for --demangle

2014-10-29T12:30:18Z

Replace "Disable" with "Enable", since --demangle option enables symbol demangling, not disable it. perf probe has --demangle and --no-demangle options, but the command-line help (--help) shows only --demangle option. So it should explain about --demangle.

perf tools: Fix report -F dso_from for data without branch info
